Hummer EV Road Trip to Las Vegas: $85.20 Charging Stop, 142 kWh in One Hour, and What the 85% Station Cap Means

A GMC Hummer EV driver shared receipts from a Las Vegas road trip, including an $85.20 charging stop in Barstow that delivered 142 kWh in about an hour, taking the battery from 23% to 99%. The session averaged roughly 142 kW, almost identical to the average at a second stop in Las Vegas, even though that stop was much shorter. Peak rates hit 305 kW in Barstow and 180 kW in Vegas, but the receipts do not show the full charging curve. The article also explains Electrify America's Congestion Reduction Pilot, which automatically stops charging at 85% at selected high-demand stations. That policy matters for EV trip planning, especially for large battery vehicles like the Hummer EV. The driver's experience highlights why checking station rules, not just peak charging speeds, is part of real-world EV travel.

Good real world data point. 142 kWh in an hour at 60 cents a kWh is steep, but the average charge rate around 142 kW is what matters for travel planning. The 85% cap at busy stations makes sense if it keeps lines moving, though it is another thing to check before you plug in.

The Barstow receipt is useful because it shows a full stop from 23 to 99 percent. Most charging posts only quote peak rates. Average rate over the whole session is the number that actually tells you how long a road trip stop will take.

Two receipts, almost identical average rates around 140 kW. That is more telling than the 305 kW peak. Charging curves slow down near the top, so the 99 percent stop took an hour. The 85 percent pilot is a reasonable way to cut dwell time at crowded urban stations.

The Electrify America 85% cap is a congestion measure, not a technical limit. It trades a bit of convenience for throughput. Worth watching whether it spreads to highway corridors, because that would change trip planning for bigger battery EVs like the Hummer.

Article does a good job separating the $85 stop from total trip cost. Home charging and missing receipts matter. Public fast charging at 60 cents per kWh is close to gas money for a vehicle this heavy, so the efficiency side still needs work.
