A leading US manufacturer of electric vehicles contacted Valence for battery solutions to power their battery electric vehicles (BEV) for multiple applications with a  diverse range of transportation options.

Battery electric walk-in delivery truckBattery Electric walk-in delivery trucks

The manufacturer’s class 5 and class 6 all-electric walk-in vans and medium-duty commercial trucks required a battery solution that would deliver up to 90-mile  range between recharging, top speeds of 65 miles per hour, and excellent hill performance.
Valence delivered a 360 V, 99-kWh modular system based on the U27-12XP U-Charge battery modules and the BMS-HV Battery Management technology.

Range Extended Electric Vehicles (REEV)

Range Extended Electric VehicleIn order to unveil the utility industry’s first electric hybrid drivetrain Class 5 trucks, the same manufacturer looked to Valence to provide the power and energy to achieve all-electric range of 45 miles and fuel savings of up to 30 percent when the units are operating in hybrid mode. Additionally, the end user, one of the largest combined natural gas and electric utilities in the US, required that the trucks (bucket trucks, flat beds, and other service trucks) offer up to 75 kW of exportable power that could be used to provide power to the grid during planned or unplanned outages.

Once again, Valence delivered with a 350V, 54-kWh modular system based on a specially designed Valence battery module using our high power cell.
