An EVSE will provide an electrical supply with a safety earthing connection to the vehicle for charging. There are several layers of safety features to protect the user from potential electrical and fire hazards while connecting, disconnecting, and charging the vehicle. Once connected to the vehicle, the charging station informs the vehicle that power is available and at what level. The vehicle then takes over, initiates, and takes full control of the power transfer. During charging, the plug connector is locked to the vehicle socket until the user stops charging, or if charging is completed. If any electrical fault occurs, the station will also stop the power transfer immediately by de-energising the cable.

Charging is only safe with the right equipment The good news is, charging an EV is very safe and easy when done with properly with safety certified EVSE. The challenge is that not ALL charging stations on the market are independently safety tested and certified. To address this issue, a nationwide electric vehicle (EV) charging standard TR25:2022 has been established for the EV charging system in Singapore.
