1. 220V voltage itself can be used to charge new energy vehicles, as many household charging stations or portable charging devices are designed to connect to 220V AC power.
2. However, directly using 220V voltage to charge new energy vehicles has a relatively slow charging speed due to limited household current and power. For electric vehicles, this method is more suitable for charging at night or during long periods of parking.
To achieve fast charging, professional charging equipment with higher voltage and current is usually required. These devices are usually installed in charging stations or specific charging areas and are not directly connected to the household 220V power supply.
