Video Summary
Sure, here is the summary of the review.The first answer is:
- Charging a GM Ultium-powered pickup like the GMC Hummer EV and upcoming Silverado/Sierra EV can vary.
- Four charging scenarios are common for electric vehicles and are as follows: a 120-volt outlet will only add about 1 mile of range per hour; a 220-volt plug-in charger will charge the Hummer EV by nearly 5x and the unit can deliver up to 50 amps of power at 240 volts; DC fast chargers can add 9 miles of range per hour.
- To use the 220-volt charger, a NEMA 14-50 outlet must be installed.
- Charging with the 120-volt charger is not as effective because it adds about 1 mile of added range per hour.
- DC Fast charging can charge the Hummer from 20% to 80% in about 35 minutes but can have a fee.
