Maximum Range, Strategic Charging
The GMC Hummer EV SUV packs an exceptional 170 kWh battery — one of the largest in the EV market. This delivers outstanding range for even the most demanding journeys, but also means charging strategy becomes critically important for time management.
With a 7.4kW home wallbox, a full 10–80% charge takes approximately 17h 52m. For practical daily use, overnight charging is essential. On the road, DC rapid chargers (50kW) deliver 10–80% in around 2h 39m, while ultra-rapid chargers (150kW) cut this to roughly 53 min.
Charging Tip
With the GMC Hummer EV SUV's large battery, a 22kW AC charger or DC fast charger access is strongly recommended. Plan charging stops at 150kW+ stations for road trips to minimise waiting time.
