Fast Chargers - Fast chargers are characteristically rated at either 7 kW or 22 kW. Most of the fast chargers deliver AC charging, though some networks have been installing 25 kW DC chargers with CCS or CHAdeMO connectors.
Slow Chargers - Most slow charging units have been rated at up to 3 kW with some lamp-post chargers being rated at 6 kW. Charging times differ based on the charging unit and the EV that is being charged.
