AutoBeta(AutoBeta.net)03/07 Report--

Tesla put the world's first V3 super-charging pile into use in the United States on Wednesday night local time. According to the V3 details released by Tesla, the V3 has a maximum power of 250kW. Tesla's most efficient vehicles, such as the long-range Model 3, can be recharged with a range of 75 miles in five minutes and up to 1000 mph (about 1610 km / h). Tesla said that compared with the V2 version, the V3 charging pile can save users 50 per cent of the charging time, which takes the average user only 15 minutes.

The new pile adopts a new liquid-cooled cable design, which is lighter, more flexible and more efficient. Tesla said that the first beta supercharging station has been opened in the San Francisco Bay area and will expand nationwide in the second and third quarters, and to Europe and the Asia-Pacific region in the fourth quarter.

Compared with V2, V3 charging pile not only doubles the charging efficiency, but also does not affect the power of multiple cars in the same charging station, that is, the maximum charge of one car is 250 kilowatts and the maximum charging time of two cars is 250 kilowatts. In addition, when the vehicle navigates to the supercharging station, the battery will automatically enter the charging state and be heated in advance to ensure that the charging gun is plugged into the fast charging state directly, which is said to increase the theoretical charging speed by 25%.

Tesla has begun to push updates to Model 3 owners in the United States, and the V3 super charger will be available for more Model 3, while the physical key of Model 3 also adds a summoning function. Due to the battery specifications, the V3 overcharge efficiency is only applicable to the software updated Model 3, while Tesla will upgrade the 120kW V2 charging post to 145kW peak power, and updates for Model S and Model X will be pushed in the next few months.

After the official release of the V3 super charging pile, netizen @ PrivaterBOK concluded that when Model 3 uses the V3 super charging pile to charge, the actual charging power can reach 245kW, and the previous high-speed charging state can be stable at 220kW, which is much higher than the current V2 version of 120kW.

As can be seen from the two pictures made by netizens, it only takes 15 minutes for the battery to charge from 15% to 67%. After the battery charge exceeds 50%, the charging power is stable to 135kW, and after 67%, the charging power drops back to 91kW.

According to the feedback after @ PrivaterBOK measurement, the Model Shopper X with 18650 battery can not reach the charging power of 21700 battery (higher energy density) Model 3 under the V3 charging pile, but it can still be raised to the maximum 150kW, and the newer the battery, the greater the improvement. At the same time, the whole charging process is very quiet, and there is no sound of battery heating or cooling at all.

The short duration and long charging time has always been the hard wound of electric vehicles, and the power battery technology has been unable to break through for a long time. Most electric vehicles have a range of only 300 to 500 kilometers, but the charging power has been developing all the time. Tesla V3 super charging pile can now charge 5 minutes to increase the mileage by 120km, which is a big increase, but it is not clear whether the battery life will be affected in this mode.

Unlike Tesla, NIO has always been keen on power exchange mode. In November last year, the power exchange network of the NIO Beijing-Hong Kong-Macao Expressway was officially completed. The total length of the Beijing-Hong Kong-Macao Expressway is about 2285 km. A total of 18 NIO power stations are located in 14 service areas around Shijiazhuang, Zhengzhou, Wuhan, Changsha, Guangzhou and other key cities. According to NIO's plan, more than 1100 exchange stations will be built across the country by 2020, putting in more than 1200 mobile charging cars.

Tesla V3 super charging pile greatly shortens the charging time, after the measured vehicle from 10% electricity to 80% lighting can basically be controlled within half an hour, this efficiency has almost caught up with the power change mode.
