"How to charge?"- this is probably the first question that arises in a person interested in electric vehicles. And in the conditions of Belarus - the question is doubly interesting. We will approach it on the example of the European Tesla Model S as the first decent electric car that is now on the market. We continue the promised cycle of publications.
Let's remember physics: volts, amperes and kilowatts
First, some basic information about electric current. If you did well in school and know how volts differ from amps and kilowatts, you can safely skip this information.
The battery capacity of a car is measured in kilowatt-hours, in our case the battery has a capacity of 85 kWh. This means that, theoretically, it can produce 85 kW of power for one hour or, respectively, 85 hours to produce 1 kW. To replenish the battery, you need to do the opposite - apply 85 kW to it for an hour, or apply 1 kW to it for 85 hours. Of course, in reality there are losses, and charging does not always go at the same speed, but the general idea is this.
A watt as a unit of power is a volt (voltage) multiplied by an ampere (current). To understand the difference between current and voltage, the water analogy is best. Voltage is, figuratively speaking, the pressure of water, and current strength is the diameter of the pipe. To pump the same volume of water (kilowatt-hours), you can, for example, pump water through a narrow pipe with a high head or a wide pipe with a low head.
If the pipe is wide and with high pressure, then the filling process is fast. Otherwise, slowly. For high voltage good conductor insulation is needed (thick pipe wall), for great strength current - sufficient cable cross-section (pipe thickness).
Now let's talk about sockets. A typical household euro socket has a nominal voltage of 220 V and a maximum current, usually 16 A or less. If we multiply the voltage by the current, or 220 V × 16 A, we get maximum power consumer at 3520 W, or about 3.5 kW.
Another common type of outlet is three-phase, with an interphase voltage of 380 V (the voltage of each phase is the same 220 V). It is less common in everyday life (electric stoves), but is ubiquitous in production, where powerful equipment is used. Most often, a three-phase socket has the same maximum current of 16 A, which, taking into account three phases, gives us 220 V × 16 A × 3 = 10.5 kW. This European-style socket has a red color and five contacts arranged in a circle. For convenience, we will call it a red rosette.
There are also single-phase sockets for 32 A ( of blue color), but they are extremely rare.
Since the power supply uses alternating current, and the battery is charged with constant current, it must be "straightened" using a charger. The same thing happens when you charge your laptop or mobile phone. Only in the case of Tesla charger the device is installed inside the vehicle. IN basic configuration The Model S comes with one 11kW charger, and you can optionally add a second one for a total charging power of 22kW.
Also included with the machine is the so-called Mobile Connector, which is similar in shape to a charger, although in fact it is just smart connection cable. For the German market, two adapters are included: one for a regular Euro socket, the other for a three-phase red socket. And that's just what we need! In the case of the American Model S, you will receive a set of single-phase American sockets different power and the inability to charge from a three-phase outlet in principle! This is the main and very significant limitation of "American women".
Mobile Connector
The car itself, destined for Europe, houses the Mennekes Type 2 charging connector. Introduced in 2009, it was adopted as a single European standard for electric vehicles. Today it is used in Renault Zoe and BMW i3. The main advantage of Type 2 is the ability to work with both direct and alternating current, with a single or three-phase network. In addition, it is much safer than conventional plug-in connections, since the transfer of energy begins only after the plug is fully connected and the car and the cable “agree” among themselves on the type electric current and charging power. In the case of the American Model S, the car will have a connector of its own unique design, more compact, but not supporting three-phase current.
First charge - at the car wash!
Now that we have dealt with the cables and sockets, you can start charging. For the first time in Belarus, our car was charged at the Peugeot car wash. The employees were sympathetic to the electric car and allowed to use their three-phase red socket. As it turns out, powerful professional sinks high pressure use just this type.
Open the trunk, take out the Mobile Connector, plug it into a power outlet. The indicator lights up green - everything is ready for charging. On the opposite side of the cable there is a handle with a button and a Type 2 connector. We press the button in the handle, and in taillight With driver's side the door opens. We insert the connector, three LEDs in the headlight start blinking green - charging has started!
On the screen in the Tesla cabin, you can see the mains voltage of 230 V (in our case, phase) and the current strength. The car gradually begins to increase the current and at the same time monitors the voltage. If suddenly a voltage drop is detected with an increase in power or its fluctuation, the current strength will be limited. This is how network overload protection works.
In our case, the wiring was quite new, so the car quickly reached the maximum for of this type 16 A sockets and started charging at a power of 11 kW. About a quarter of the battery needed to be charged to a "full tank" and the estimated charge time was 2 hours. Not fast, to say the least. Nevertheless, while the car was put in order, it was possible to charge almost completely. Good for a start. Full charge from the red socket will last about 8 hours.
If the car is closed during charging, the Mobile Connector is blocked in the connector and all illumination is turned off so as not to attract too much attention.
After driving around the city, it's time to check the charging speed in the garage from ordinary socket. And here came the bummer: the Mobile Connector blinked red four times, which is an indication of the lack of grounding. No "ground" - no charge. Very often, electricians are not serious about grounding, so you can find ungrounded or “zeroed” sockets everywhere. So the presence of a euro socket in the wall does not guarantee you the opportunity to recharge from it. Even if you are lucky and there is a ground, the charging speed will be four times slower than the red socket, since the maximum power in this case only 3 kW. A full charge will take over 33 hours!
If you want to charge at home faster than the red socket allows, you must optional equipment. One charger installed in the car, by default, allows you to charge at a power of 11 kW. The optional second one can be installed directly at the factory or added later, in which case the maximum charging power will be 22 kW. In addition, you will need to install the High Power Wall Connector (HPWC), which is almost a complete analogue of the Mobile Connector, only installed permanently and has a thicker cable.
If HPWC is the only alternative in America, in Europe you can buy a similar device with a Type 2 connector and the corresponding cable. But in the case of a cable from third party manufacturers you will not be able to open the charging hatch by pressing the button in the cable. You will have to open it from the central screen or from a mobile phone through the application, which is not very convenient. Power of 22 kW will allow you to fully charge in 4 hours.
But perhaps the biggest problem with 22 kW charging is allocating the appropriate power. If you can't get 22 kW at the car parking lot, it doesn't make sense to order a second charger in the car and HPWC. For convenience in the garage, it is best to purchase a second Mobile Connector and use it as a stationary one, permanently connected to a power outlet. And carry the original with you in the trunk, just in case you need to recharge on the road. Most likely, on the way you will be charged from a regular (if you are lucky with grounding) or a red outlet. Even if you suddenly find a Type 2 connector with a power of 22 kW at the Belarusian electric filling station of the future, then 4 hours is still too long for recharging during the day. In the case of charging at night, the difference of 4 or 8 hours does not matter.
Why cities don't need electric refueling
Now let's talk about electric stations. This is the most asked question to the owner of an electric car. Oddly enough, in the city, Tesla owners do not need electric stations in principle. Real stock travel is 300-350 km, in the worst case (when minus 20 Celsius and traffic jams) it drops to 200 km. In the evening you put the car on charge (just like a mobile phone), and in the morning you always " full tank» (if red outlet or HPWC). In the case of a conventional outlet, a “full tank” may not work, especially in winter. Therefore, the best electric refueling is a red outlet in your home.
Is it possible to operate a Tesla normally if you do not have a garage or parking space? Since the installation of the home red socket was delayed, and the euro socket in the garage did not have grounding, we drove the first thousand kilometers in the "parking near the house" mode. Thanks to the kind people at the Peugeot car wash, at Atlant-M Britannia and DAF Trucks, we used their red sockets every few days. In all cases, there were no problems, with the exception of two points - you have to wait a long time for charging to complete and wipe the cable from dust and dirt before putting it back in the trunk. Night charging is much more pleasant: you sleep - the car is charging. During the day it is very inconvenient.
The Model S can be charged at any time without having to wait until it is completely empty. The battery has no memory effect, will not recharge if you leave it plugged in for for a long time. The manufacturer generally recommends leaving it connected all the time until you drive. This is especially important in winter severe frost. You can remotely turn on the climate control and warm up both the interior and the car battery from the mains. Another handy feature is the automatic marking on the map of all the places where you have ever charged. Thus, after some time, own card"electric stations".
Is it possible to "reset the extension cord" from the apartment? Theoretically yes, practically no. Firstly, it will be unsafe in rain or snow, and secondly, charging from a regular outlet takes a catastrophically long time. Therefore, in order to use an electric car normally, installing a three-phase red socket next to permanent place parking at work or at home is priority which should be taken care of in advance.
To install a three-phase socket at home, you, in a good way, will need to make a project, go through the stages of approvals, mount sockets, lay cables and, it is possible, install an additional electricity meter. All this can be undertaken by a specialized organization that deals with electrics. In each case, the timing, cost, availability will vary electrical power. Therefore, before thinking about buying an electric car, you definitely need to understand for yourself how you will solve the issue of charging.
But what about the electric refueling on the A-100, you ask? After all, the slogan on a huge poster reads “Electric cars refuel here”, and on a special pedestal, like a monument, stands a lonely nissan leaf. As it turned out from a conversation with the gas station staff, they have no idea how it works: “The bosses are playing this electric car, and we don’t know anything.”
On the second attempt, with a request to clarify the situation, the employee went to his superiors, who did not even deign to leave the office and look at the first living customer of an electric refueling station in the country. "It is for official use», - said, as she cut off, the lady at the cash desk after a visit to the authorities.
We approached Nissan and found out that the “subcompact car” is charged by “slow” charging through the old Type 1 connector. In any case, without dancing with adapters that are not there, Model S will not be able to charge there, and it will take too much time. Thus, "electric refueling" on the "A-100" is simply not a completely correct marketing ploy.
If in the city of Tesla - this is almost an ideal option for everyday driving, That long journeys on an electric car in conditions of Eastern Europe currently represent big problem. You can still go to Vilnius by agreeing there with the owner of the red socket for the night, but to Moscow - no longer. This requires a network of fast chargers that would be on the tracks.
The main difference between fast charging and slow charging is that it immediately supplies direct current. high power directly to the battery, bypassing the charger built into the car. in the USA and Europe Tesla develops its own network of electric charging stations, which are called Supercharger. Depending on the version, they charge with direct current with a voltage of 400 V and a power of 90 to 135 kW. Moreover, stations with a capacity of 150 kW will be launched in the summer. For Tesla Model S owners, the use of these chargers is unlimited and free of charge. This charge allows you to replenish half the battery in 20 minutes.
It will take more time to fully charge the battery, because when charging after 80% of full capacity, the battery starts to heat up more and the power must be reduced. The company has very ambitious development plans Supercharger networks in Western Europe and the USA. As for Eastern Europe, no specific information has yet been announced.

The second, universal, fast charging option is the Chademo network. The idea is the same, but not free and with a maximum power of 50 kW. For Model S, there is a special adapter that allows you to charge from these stations. Chademo connector has enough big size and nowhere near as comfortable as the Type 2.
Tesla cars are only gaining their popularity in Russia when in the USA vehicle found almost as often as the "Zhiguli" in the CIS. The only thing that stops the popularization of electric cars in Russia is an insufficient amount stations for charging electric vehicles. Most gas stations are located within Moscow and St. Petersburg. Moving outside these cities, you can see that the number of gas stations is gradually decreasing, while in the US the number of stations for electric vehicles is almost equal to the number of conventional gas stations. In the article we will consider the lineup Tesla vehicles and the power reserve of these vehicles.
About company
Tesla is an American company that produces premium electric vehicles. Was founded in 2003. It is named after the famous physicist and electrical engineer Nikola Tesla. On this moment Elon Musk leads this company.
The company gained the greatest popularity after the release of the first generation Tesla Model S, which went on sale in 2012. The car had two modifications: one with a power of 60 kWh, the second - 85 kWh. The electric motor is located at the rear of the car. In 2015, a version with two engines per axle was introduced. After that, each car of the company is equipped with two engines. The Tesla S has a range of 442 to 502 kilometers.
In 2012, Tesla's Model S was awarded "Car of the Year" by the renowned Motor Trend magazine.
Technical features of model X
Specifications models depend on the configuration, which have this car three:
"Tesla" model X
Model X from Tesla is an SUV equipped with two electric motors. Most of the power is located in rear engine for technical reasons.
Externally, the car looks very futuristic, reminiscent of something extraterrestrial. Main Feature this model from the company "Tesla" are rear doors that open like the wings of a bird. This decision was applied by designers for more comfortable fit and disembarkation of second and third row passengers. It is also an advantage when parking, as it requires only 30 centimeters of free space on the sides of the car, which is significantly less than conventional vehicles.
Optionally, the buyer can purchase a five-, six- and seven-seater SUV. Also useful feature is the third row of seats, which is able to fold flush with the floor, which increases the volume luggage compartment three times.
Car prices start at $132,000 (8,683,000 rubles) for the base trim and $142,000 (9,339,000) for the top trim with an engine power of 772 horsepower. In this configuration maximum margin The Tesla X model travels 400 kilometers, which is 11 kilometers less than the 90D configuration.
Model X power reserve
Power reserve X depends on equipment. At minimum configuration this figure is 354 kilometers, and the maximum is 411 kilometers. The P90D version has a range of 400 kilometers, after which the car will need to be charged, which lasts from 4 to 12 hours depending on the current, charging method and plug.
Reviews about "Tesla" Х
The main advantage is that the car does not pollute environment. car battery consists of many small 18650 batteries. Therefore, after a cell fails, you can find a damaged cell and replace it without buying a whole assembly of batteries.
Also an important advantage is aluminum body, which is not susceptible to corrosion and weighs less than steel. Appearance car resembles many serial crossovers, but still has its own characteristics, for example, rear wing doors.
A huge tablet with which you can control all the functions of the car, including navigation system, watching videos, movies, listening to tracks and much more.
Tesla's power reserve directly depends on the temperature overboard. This is considered a disadvantage, since the built-in lithium-ion batteries very demanding on temperature and weather conditions.
As for the seasons, it also has its own characteristics:
Technical features of the S model
The base model S uses liquid cooling. The car is equipped with an electric motor alternating current capacity 362 horsepower. The car accelerates to hundreds in 2.7 seconds, which is faster than many serial sedans premium.
This car is considered the quietest serial electric car. The top-end equipment costs 140 thousand dollars (9,200,000 rubles), the basic one costs half as much. The range of the top-end Tesla S is 507 kilometers, which is almost 100 kilometers more than the SUV of this company.
Model S: description
Externally, the Tesla Model S is a bit like " Ford Mondeo". This is where their similarity ends. The first thing owners notice petrol cars mobile - the absence of a radiator grille, since it is simply not needed here. The front optics look very fresh, here it is fully LED, has the so-called cilia on the top and bottom of the headlight. The Tesla logo is located in a small opening between the bumper and the bonnet.
External door handles the same as in modern models"Lexus" and "Range Rover", namely, move forward when the car is unlocked from the key and retract when it is locked.
The roof of the car is panoramic, inside the cabin looks very attractive. Thanks to this, there is always enough light in the cabin. Since outwardly the car is not particularly remarkable, it is worth talking about its interior.
Inside the car looks quite minimalist, except for the large touch screen. He is at the same time on-board computer, and a multimedia center, and a navigation system.
The car became popular due to the introduction of not only lane keeping, but also full autopilot. To turn it on, there are special buttons on the steering wheel. But you can’t just break away from the steering wheel, since the car will require hands on the steering wheel once a minute, otherwise it will emergency stop and will not move until it switches from autopilot to manual control.
Since the car is fully electric, the presence of mechanical box gear is meaningless. Therefore, the car has a speedless gearbox. Gear shifting is not audible at all, as well as third-party noise, with the exception of the quietest hum of the electric motor.
This car will not go forever, so it needs to be charged. Many filling stations have at least one electric vehicle charging station that can fill up a car in a matter of hours.
Model S range
The range of the car in the basic configuration is 412 kilometers, in the top one, which is designated P100D - 507 kilometers. The charging time of this car will be the same hours as that of a Tesla SUV. The Tesla S battery assembly consists of 16 blocks, each of which must be replaced separately.
After testing the Tesla car, the Model S was named one of the most safe cars on the market, even considering the fact that it consists entirely of electrics. He received five stars from the "Euro NKAP" commission.
Impressions from Tesla operation winter in Russia
To bookmarks
Alexander Chachava, managing partner of the LETA Capital venture fund, shared his experience of operating a Tesla car in Moscow, and also gave some advice on using a car in winter.
For a year and a half I have been driving Tesla car and already dashed off 14 thousand km. Heard that consumer qualities fall in the second year of ownership, the batteries work worse, the car starts to have problems.
I did not notice anything, everything works like clockwork. I don’t know what will happen at 50 thousand km, but so far everything is fine. The lack of maintenance is a little annoying, Tesla told me that no action is needed with the machine, it will report a malfunction if something happens. I am so accustomed to the instantaneous response of the electric motor that I am surprised at first by the delay after gas on gas cars, even on BMWs.
But the sound of the engine is a bit lacking for completeness of sensations, although sometimes you like silence when you want to sit in silence, and not drive. In general, the engine roar option that can be ordered from an electric car tuning studio is not as idiotic as it seems at first glance.
Stumbled upon Adventure. I checked it with a search for Aftershock - it didn’t seem to exist yet. So
Company Tesla Motors starts charging for recharging its electric vehicles at Supercharger network stations.
So far the owners Tesla electric vehicles could recharge their car using the Supercharger installation for free. However, at the end of last year it became known that the future owners of the company's electric cars will have to pay for energy consumption. And now Tesla Motors has revealed its pricing policy.
So, it is reported that paid recharging is being introduced for Tesla Model S and Model X buyers who placed an order after January 15 this year. They will be able to receive 400 kWh of energy annually free of charge, which is enough to cover a distance of about 1,000 miles (about 1,600 km). After that, recharging will be paid.
In North America, the price is set separately for each state or each province, in other regions - separately for each country.
In most cases, the cost is indicated for one kWh. So, in California the price is $0.20 per kWh, and in Florida - $0.13 per kWh. But in some regions, the cost is calculated depending on the time of recharging. More details from pricing policy can be consulted.
It is noted that all funds received from the owners of electric vehicles for the consumed energy will be directed to further development Supercharger networks. By the way, today there are about 800 stations. Tesla charging, hosting a total of almost 5,100 Supercharger installations.
Each charge level provides different speed charge, and different configurations in Tesla have the maximum charge capacity they can accept.
The external charger is a wall-mounted charging port that provides power from the mains or another source such as solar panels.
The time it takes for a Tesla battery to be fully charged depends on the level of charge, the maximum power output of the station, and the maximum energy consumption of the electric car.
Tesla provides several types of adapters - J1772, Mennekes Type 2 and CHAdeMO - that allow you to charge your car battery from common types of public charging stations in different regions.
Tesla has 3 levels of chargers, each of which works in different levels voltage.
Trickle charging
Level 1 or "trickle charging" uses standard 120 volt outlets. Tesla can be charged from this outlet using a NEMA 5-15 adapter, which is supplied in standard equipment.
Power supply 1.4 kW, and 1 hour Charging Model S / X 100D will charge the battery for ~ 3.2 km of run. Power supply - 1.4 kW.
The advantage for Tesla owners is the ability to charge from a standard 120V outlet via a "trickle charging" adapter, and since a 110/120V adapter comes standard, it doesn't need to be purchased separately and the battery can be charged almost anywhere.
On the negative side, it is worth noting that charging is very slow and will take all night to charge the battery for ~50 km.
Charging-240V
Level 2 - from a 240V socket, as well as a wireless charger Tesla device"Connectors Plugless" and most public charging stations.
Different charging device draw varying amounts of electrical current through a 240 volt network. More current = more power= more fast charging. Level 2 chargers provide 3.3 to 17.2 kW of power, allowing you to charge from 15 to 80 km per hour with a NEMA 14-50 adapter.
The maximum power consumption is 11.5 or 17.2 kW, depending on the configuration of the Tesla Model , since the Model S comes standard with an 11.5-kW charger, which provides a charge for a run of ~50 km per hour in 1 hour. Modifications with the "High Ampage Charger" option can take up to 17.2 kW of power, and, accordingly, ~ 83 km per hour.
Fully charge Battery Model S maybe ~10 hours, Model X 12 hours.
Tesla also offers charging stations for connecting wall connectors at home. The wall connector can fully charge a Tesla Model S battery in 6 to 9 hours and a Model X battery in 6 to 10 hours.
The advantage of level 2 is perhaps faster charging compared to level 1 (~15 times), in the same home conditions.
Supercharging - 480V
Level 3 is fast chargers direct current(480 volts), which are available at public charging stations and Tesla's Supercharger.
Of the advantages of this type of charging, it is worth noting that 30 minutes is enough to charge the battery with a range of ~ 270 km.
Energy supply - 140 kW.
Despite the large number of charging stations in the United States, about 90% of Tesla electric car owners charge the battery at home from a household outlet.
Instruction
To charge the Tesla, you need to connect the charging cable to the socket, which is located under the cover built into the rear combination lamp on the driver's side.
After unlocking the vehicle or recognizing the key, press and hold the button on the Tesla charging cable. If your cable doesn't have this button, select Controls > Charge Port, or click the Charge Port icon. battery on the top panel touch screen, and then select Open Charge Port from the Charging menu.
If the cable is not connected for several minutes, then after opening the connector cover, the latch is blocked. In such a case, open the charging port cover using the touch screen and do not use excessive force to open the cover, which may damage the latch and prevent it from holding the cover in the closed position.
On charging station common use connect the adapter to the charging socket of the station. The car is equipped with the most common adapters for each region. Depending on the type of equipment used, it may be necessary to use the controls on the charging equipment to control the start/stop of charging.
When the connector is opened, a white light turns on, which subsequently goes out if the charging cable is not connected.
Connection
If necessary, use the touch screen to change the voltage and current limits.
When using a mobile charging cable, first connect it to the household outlet and then to the car.
Align the plug with the vehicle's charging socket and insert as far as it will go. If the plug is inserted correctly, charging will start automatically only if the charging cable plug lock is latched, the shift lever on the steering wheel is in the "P" park position and the battery is in the correct position. temperature regime(if the battery needs to be warmed up or cooled down, the charging process may be delayed).
If the vehicle is connected to the grid, but there is no active charging process, it will draw energy from the grid and not from the battery. For example, the touch screen of a parked and plugged in car will be powered from the mains rather than from the battery.
While charging
During the charging of the battery of the Tesla electric car, the backlight of the charging connector signals in green, and on dashboard displays the status of the process itself. The flashing frequency of the connector illumination decreases as the charge level increases. When completed, the lamp stops flashing and remains solid green. If the car is locked, the illumination of the connector and the display in the cabin does not work.
A red backlight indicates a malfunction. Check for a message describing the problem on the instrument cluster or touch screen. The cause of the malfunction may be such a banal factor as, for example, a power outage. In this case, charging will automatically resume after power is restored.
Possible extraneous noise, this is due to the fact that at high currents, a refrigerant compressor and a fan are connected to work to protect the battery from overheating.
You can stop charging at any time by disconnecting the charging cable or by pressing Stop Charging on the touch screen.
To disconnect the charging cable:
- Press and hold the button on the Tesla cable plug to release the latch;
- Disconnect the plug from the charging socket;
- Close the connector cover;
To prevent unauthorized disconnection of the charging cable, it can only be disconnected after unlocking the vehicle or recognizing the key.
When you double press the key key, the charging will be automatically stopped. If the charging cable is not disconnected within 60 seconds, the charging process will resume.
Tesla recommends leaving the electric car connected to a power source, in case the car is not going to be used for an extended period of time, this will prevent complete discharge and help maintain the optimal charge of the high-voltage battery.
Change settings
The settings window is displayed on the touch screen every time you open the charging port cover.
To display the charging settings at any time, press the battery icon on the top touch screen bar or select Controls > Charging (at the top right of the Controls window).
1. Condition; 2. Adjustment according to the needs of the power reserve; 3. Planning with reference to the charging point; 4. Button to open the cover of the charging connector; 5. Maximum current, which is available for the connected cable. It will be set automatically if the corresponding value has not been lowered previously. During charging from a three-phase network, the current value for one phase is displayed (up to 32 A), and on the right status indicator, the “Three-phase” symbol is displayed in front of the current value. If necessary, press the up or down arrow to change the amount of charging current;
Depending on the software version and region, the on-screen controls may differ.
State
The following illustration is for illustrative purposes only and may vary slightly depending on the version. software and region.
1. Hourly pace; 2. Total available estimated range and energy, but settings can be changed; 3. Supply current available from the connected power supply; 4. Calculation of power reserve/energy during the current session; 5. Status display; 6. Voltage supplied through the charging cable;
In case of detection of voltage drops at the time of battery recharging, the current is automatically reduced by 25%, for example, from 40 to 30 A. Automatic current reduction increases operational reliability network and provides security if household wiring, outlet, adapter or cable is not rated for the current. At the same time, the possibility of increasing the charging current manually remains, however Tesla recommends charging more than low current until surges are eliminated and a stable power supply is restored at the point of charge.
