The new Hummers are electric, and GM says the necessary cord to let them charge other electric vehicles will be included on all Hummers equipped with the Power Station. So drivers of electric off-roaders will perhaps be rescued by a friendly Hummer. This is the future of the jump start.
GMC hasn’t specified the size of either model’s battery, but it said the largest Ultium battery would hold 200.0 kWh. We think the SUV’s will be about 167.0 kWh. In typical Level 1 (120 volt) or Level 2 (240 volt) charging, alternating current (AC) is converted to direct current (DC), and that energy is stored in the battery pack. The Power Station generator uses an inverter to convert the battery’s DC energy back to AC so it can power what is plugged into its standard J1772 charging port.
