What is the difference between Tesla v3 and v2?

The differences between Tesla v3 and v2 are as follows: 1. Faster charging speed: In May 219, Tesla increased the peak power of V2 super-charged piles from 12kW to 145kW to meet the market demand, which further improved the charging speed. However, compared with the V2 super-charged pile with the highest peak power of 25kW, the charging speed of the V2 super-charged pile for electric vehicles is obviously much slower. 2. Lighter and more flexible: For the convenience of female car owners with less strength, the charging gun is newly designed by using Tesla V3 super-charged piles. By using liquid-cooled wires, the diameter of the wires is reduced from V2' s 36.3mm to 23.87mm, which makes it easier for car owners to plug and plug the charging gun. 3. Add new functions: V3 super-charged pile has the new function of "battery preheating on the road". On the way to V3 super-charged pile charging by car navigation, the car will automatically preheat the battery to ensure that the battery can reach the ideal charging temperature at the initial stage of charging. According to Tesla's calculation, the superposition preheating function of V3 super charging pile will eventually reduce the average charging time of users by 5%.
