SeriousElectrics & ElectronicsThe all-electric e-2008 incorporates an AC on-board charger (single-phase 7.4 kW or three-phase 11 kW) manufactured by Mahle. Internal electronics and isolation circuitry within early units are susceptible to failure, causing charging to abort immediately or tripping domestic electricity supplies. When the OBC fails, the car cannot be charged via AC wallboxes, showing high-voltage electrical warnings.
