Bidirectional 6.6 kW OBC with 3.3 kW V2L output
The GC-BID-6.6KW-2KW is a liquid-cooled two-in-one power unit combining a 6.6 kW bidirectional on-board charger and a 2.0 kW DC/DC converter. In charging mode it converts 85–265 VAC single-phase grid power into 240–450 VDC for the traction battery. In discharge mode it inverts battery power into 220 VAC at up to 3.3 kW, so the vehicle can power tools, appliances and emergency equipment (vehicle-to-load). The integrated DC/DC supplies the 14 V low-voltage system with up to 2.0 kW.
