Continental unveils AllCharge charging system; using the EV powertrain as a universal charger; up to 800V and 350 kW and all types of stations

Green Car Congress

Continental has developed innovative charging technology called “AllCharge” that uses the electric powertrain of an EV as a universal charger supporting all types of cable-based charging stations. AllCharge can always use the maximum output rate—up to 800V and 350 kW—at all types of stations: single-phase and three-phase AC or high-speed DC. In the case of DC current, the current from the charging station flows directly through the inverter to the battery.
