Battery-backed dc fast charging expands for Colorado fleets

By Michelle Froese | August 31, 2026

Xos received a follow-on order from Xcel Energy for three additional Xos Hub mobile energy storage and charging systems to support electric vehicle (EV) charging in Colorado.

Two units will be deployed at Xcel Energy service centers in Arvada and Grand Junction to provide dc fast charging for fleet vehicles. A third unit will support temporary EV charging in the Denver area during transmission construction projects that interrupt access to residential charging.

The Xos Hub combines battery energy storage with dc fast charging in a mobile system that can be deployed without waiting for permanent charging infrastructure upgrades.

The platform is available with 210, 420, or 630 kWh of onboard battery capacity and supports up to 150 kW of charging power per CCS1 charge head.

The Hub can also recharge from several power sources, including three-phase ac utility power or an existing dc fast charger. This allows operators to charge the onboard battery when power is available and then use the stored energy to provide dc fast charging where grid capacity or permanent infrastructure is limited.

Xcel Energy first deployed two Xos Hub units in 2024. One Colorado unit has since delivered about 33,000 kWh of charging.
