The Combo Unit combines the functionality of an on-board charger (OBC) with that of a DC/DC converter. This allows the vehicle battery to be charged from an AC building/grid power source at a 6.6kW rate and the DC/DC portion provides a 14V output converted at up to a 1.2kW nominal (1.4kW max) rate from the high voltage battery. This keeps the vehicle’s low-voltage battery charged. The Combo Unit is water cooled by the vehicle’s coolant loop. This product is available in 400Vdc and 800Vdc versions.
The EVSE cable is a J1772 Type-1 Level-2 stationary charger that plugs into home or workplace 208-240VAC single-phase receptacles. This unit is equipped with a NEMA 14-50 plug, draws up to 32A and provides up to 7.5kW of charging power which is plenty to supply our Combo Unit.
NOTE: See “More Info” page for detail about J1772 charger communications.
