It can be simply understood as charging speed, the higher the power, the faster the charging.

• 7KW represents charging 7 kWh of electricity in 1 hour, which is approximately equivalent to 40 kilometers.

• 1kw represents charging 11 kWh in 1 hour, which is approximately equivalent to 60 kilometers.

• 22kW represents charging 22 kWh of electricity in one hour, which is approximately equivalent to 120 kilometers.

A 7KW household charging station only needs to be equipped with a 220V electricity meter when applying for installation, while installing 11KW and 22KW charging stations requires applying for a 380V electricity meter. Compared to this, purchasing a 7KW charging station is more convenient.
