Weilai, change the electricity, follow the car or follow the account?

Hello, do you want to change the electricity or the account number with the car? The answer is to recognize cars but not people. In other words, Weilai can provide car owners with the right to exchange electricity for free, but it only supports the replacement of batteries with the same battery capacity, and it is impossible to replace batteries with larger capacity for free. Weilai's power exchange process is also quite fast, and the whole process is fully intelligent. The driver only needs to sit in the car and can successfully change the electricity in 5 minutes. However, at present, Weilai's power exchange station has not been popularized everywhere, so in addition to power exchange station, Weilai also supports DC fast charging and AC slow charging.
