U.S. electric commercial vehicle maker Xos has expanded its mobile charging portfolio, introducing three higher-capacity configurations of its Xos Hub energy storage and charging system aimed at accelerating electrification across commercial vehicle fleets.
The Los Angeles-based company said on Jan. 26 that it will offer the Xos Hub in 210 kilowatt-hour, 420 kWh and 630 kWh versions, with prices starting at $158,000. Customer deliveries are expected to begin in the first quarter of 2026.

The new lineup is designed to serve a broad range of fleet applications, from Class 1 and 2 delivery vehicles to medium- and heavy-duty electric trucks. Xos said the modular systems can be deployed as temporary or permanent charging infrastructure, offering an alternative to fixed fast-charging installations that often require lengthy utility interconnection timelines.
“We are expanding charging access, supporting diverse fleet types, and making it more flexible to rapidly deploy charging infrastructure as the demand for electric vehicles continues to grow every year,” said Aldan Shank, director of mobile charging products at Xos.

The entry-level 210 kWh Hub is aimed at light-duty commercial fleets such as delivery vans and service vehicles and is equipped with two CCS1 charging heads, with compatibility for the North American Charging Standard available. The 420 kWh version, which replaces Xos’ previous 280 kWh model, offers four CCS1 charging heads and can recharge 15 to 20 commercial vehicles per cycle, while remaining under 10,000 pounds to allow towing by a standard three-quarter-ton pickup truck without a commercial driver’s licence.
The flagship 630 kWh configuration targets medium- and heavy-duty electric trucks. Xos said engineers were able to increase energy capacity while retaining the same physical footprint as the lower-capacity models. Multiple units can be connected, allowing up to 10 Hubs to operate together for a combined capacity exceeding 6 megawatt-hours using a single grid connection.

All three configurations are expected to carry UL 9540 A certification in 2026, enabling their use as both mobile and fixed energy storage systems. According to Xos, basic installations can be completed in days, compared with the six to 18 months often required for conventional utility-connected charging infrastructure.
The Xos Hub has already been deployed in the field with customers including SparkCharge, California’s Department of Transportation and Xcel Energy, supporting use cases ranging from roadside charging to grid resilience and utility fleet operations.
The company has also partnered with Windrose to deploy mobile charging for Class 8 electric trucks and said last year that the Xos Hub qualified for incentives under California’s Clean Off-Road Equipment Voucher Incentive Project, reducing effective costs for some fleet customers.
Xos said the expanded Hub lineup is intended to help fleet operators scale charging capacity in line with vehicle adoption while avoiding delays linked to permanent infrastructure buildouts.
