DC EV Charger Explained | Bluesky

1. What is a DC EV charger?

DC EV charger is used to charge electric vehicles.

DC EV charging equipment can be installed on the ground or the wall, installed in various public spaces, residential quarters, and charging stations, and then charged by various types of electric vehicles according to different voltage levels.

People can use RFID cards or activate them by mobile phone. Start on the 7-inch HIM  touch screen provided by the charging equipment, The display screen of the EV charger can display data such as charging amount, cost, and charging time.
