If the cost of electric cars, the popularitywhich is growing by leaps and bounds, has faded into the background, then a long time, charging still remains their significant problem. Without waiting for a breakthrough in the battery industry, Tesla, the head of which is Ilon Musk, earlier this year announced its intention to reduce the charging time of electric vehicles to 5 minutes. And she succeeded!
Recall that in March this year the company Teslaintroduced a network of stations for recharging cars called Supercharger V3, designed specifically for charging the batteries of Tesla Model 3 electric vehicles. However, such charges can only be found in California - the Supercharger of the first version and Supercharger V2 are more common in the world.

Quick charge Tesla
Fast charge power supercharger firstgeneration is limited to 120 kW, the Supercharger V2 is already capable of delivering power up to 150 kW, only this value is greatly reduced if several cars are connected to one charge. The third iteration allows the use of a current up to 250 kW: an almost twofold increase in power was achieved thanks to a new cable design, which now uses liquid cooling. But the main advantage compared to the Supercharger V2 - such stations do not need to distribute energy between several cars, so customers can always get the maximum charging power.

How much does Tesla charge?
Tesla charging time can be clearly seen on the example of the Model S car:
- Normal charging Mobile Connector (full-time) - 29 hours
- Mobile Connector using a special adapter, a NEMA 14-50 standard outlet and electrical outlet modifications - 9 hours
- High Power Wall Connector + Twin Chargers (Charging Accelerator) - 4.5 hours
- Supercharger V1 / V2 (up to 120 kW) - 1.5 hours
- Supercharger V3 - 50 minutes
Mobile Connector - essentially charging from normalso that is the longest way, and you lose access to the car for more than a day. It’s the most affordable: for example, Model 3 owners must pay for charging with the Supercharger - $ 0.28 per 1 kW (about $ 20 for a “full tank”), while the average cost of 1 kW in the US is $ 0.08. For Model S and Model X drivers, fast charging is free, but for the rest, it turns out it's cheaper to charge your electric car at home. But it will be noticeable longer.
However, when compared with refueling petrolor diesel fuel, 50 minutes for charging is also very long. It is not clear what the owner will do all this time, given that many fast charges are set away from shopping centers, cafes or restaurants.

The main chip charging stations Supercharger V3 -They are able to provide peak charging power up to 250 kW. Thanks to this, in just 5 minutes you can increase the range of the electric vehicle by 120 kilometers. Subsequently, charging will occur no longer at peak power, but at 150-200 kW.
How to charge Tesla at home
In homes most often installed either MobileConnector using a special adapter, a NEMA 14-50 standard outlet and electrical outlet modifications, or the Wall Connector, introduced earlier this year. The latter offers a faster charging time than the Mobile Connector - up to 40 amps for most Tesla vehicles, while the Mobile Connector gives a maximum of 32 amps.
How to charge Tesla in the mall
It all depends on the location, butIt is often possible to find the maximum High Power Wall Connector in shopping centers, less often Supercharger V1 or V2. Therefore, it is possible to fully charge Tesla only if you look at the director's version of Avatar. And then you have to go to the restaurant.
Somewhere you can still find fast charging - although it is often limited to 120 kW (V1).
Conventional charging for electromobiles (50 kW). With such a Tesla will be charged for a long time.
How do the batteries in Tesla
Tesla is rightly considered the leader and the mainan innovator in the development of electric vehicles and battery charging technologies. For example, the company even offers the service of a complete replacement of the Tesla Model S power subsystem in case of its damage. At special stations it takes just 90 seconds to replace the battery pack. A specially developed platform for lifting the car is used, under which the equipment for removing and installing the battery is located. Using clips and wrenches, the battery is removed from under the machine and then retracted under the platform for further recharging. And in its place is a fresh battery.
Not Tesla single?
Other manufacturers are trying to catch up with the company.from California, but they are not good at it. Now the most popular charging stations use technologies that are based on the Japanese standard CHAdeMO and offer a current of 50 kW. Even the new standard SAE J1772, the development of which was completed not so long ago, offers no more than 100 kW. Recall that BMW and General Motors are developing new charging systems based on the SAE J1772 standard. Yes, there are exceptions - for example, Volkswagen's Electrify America stations provide 350 kW of power, but they have problems with cables, so it was reported at the beginning of the year that these charging stations had to be temporarily closed.
By the way, Volkswagen has just scored an alarmcable supplier: according to him, the problem lies in liquid-cooled cables and is described as a “safety problem”. In other words, VW recognized such a charging method as unsafe. But Tesla did not stop.
Tesla battery packs are superior in capacityanalogues installed in competitive electric vehicles more than three times. That is why Tesla is promoting its technology so aggressively, ”said Arindam Maitra, senior manager of the Institute for Electrical Power Engineering Research.
According to him, the key to success is thatTesla develops and manufactures all the necessary components independently. That is what will allow the company in the shortest possible time to improve the performance of charging stations and batteries.
Is it even faster?
The main problem of fast charging at thisThe moment is overheating of the batteries. In order to prevent overheating, the external charger analyzes the state of the battery every millisecond and monitors the main indicators (voltage and temperature).
The work of the charging station and the battery should resemble the coordinated work of the clock mechanism. That's when everything will work out.
To achieve this goal will require nonot only a significant improvement in recharging stations, but also improving the interaction with the electrical network. Tesla also plans to circumvent the problem of price increases at charging stations, which will arise as a result of modernization, by installing solar panels. The company opened the first Supercharger fast charging station in September 2012. Since then, 12,888 points of fast charging have been opened in the United States and another 1,441 worldwide — including the Supercharger V1 / V2.
By the way, Tesla is now buying more than Chrysler, Land Rover, Volvo and many others.
Already in the next 2-3 years, Tesla can alsorelease the first charging stations with a capacity of 350 kW (as they will be called? V3s?). And 5 minutes of charging will not be enough for 120 kilometers, but all 200 kilometers (now Model 3 is fully charged from V3 in 37 minutes). The only problem is that such installations will be too expensive: now you will not see the usual Supercharger everywhere, not to mention the V3. Nevertheless, it is a big stone in the garden of gasoline and diesel cars. Would you switch to electric cars if they charged while you were in the supermarket? Write in our Telegram-chat.
