Does the charging station for household new energy vehicles use 7kw or 3.5kw? Firstly, let me take a look at the characteristics of these two types of charging stations:

7kw and 3.5kw are usually AC slow charging, but their rated currents are different. The 3.5kw charging station has a rated current of 16A, while the 7kw charging station has a rated current of 32A. Therefore, the 7kw charging station will definitely charge faster than the 3.5, and the charging speed will be faster. If the battery capacity of a private new energy car is 60 degrees, the 7kw charging station can be fully charged in eight or nine hours at night, but the 3.5kw charging station usually takes more than ten hours. The other two types of charging stations also have different requirements for input power connection. The editor suggests that if you use it at home, you should choose a 7kw charging station, as charging for more than ten hours is too long. A 3.5kw charging station is suitable for frequent changes in charging station locations or temporary power replenishment.
