Proterra Inc. has expanded its partnership with Lightning eMotors to power its Class 4 and Class 5 electric commercial vehicles with Proterra’s battery technology. Under a new multi-year supply agreement, Proterra contracted to supply battery systems totaling more than 900 megawatt-hours in battery storage capacity to Lightning eMotors to power up to 10,000 electric commercial vehicles between 2022 and 2025. This includes supplying Lightning eMotors with Proterra H Series battery systems for its strategic partnership with Forest River to co-produce and deploy Class 4 and Class 5 zero-emission, battery-electric shuttle buses.

The expansion builds on Proterra’s previously announced collaboration with Lightning eMotors to power the Class 3 Lightning Electric Transit commercial van using Proterra battery technology. Proterra will now also supply its battery technology to Lightning eMotors for the Lightning Electric E-450 and Lightning Electric F-550 electric commercial vehicles.

The Lightning Electric Transit van is a purpose-built Class 3 commercial electric vehicle that is available in several configurations including last-mile cargo vans, passenger vans, ambulances, school buses, and work vans.

The Lightning Electric E-450 and F-550 commercial electric vehicles are available in a shuttle bus configuration utilizing the various Forest River bus body options, and as a truck including middle mile/last mile delivery trucks, ambulances, and work trucks. Both platforms are planned to have 80kWh-160kWh of Proterra battery packs.

Designed and manufactured in the United States, Proterra battery systems leverages industry-leading energy density and a customizable design to fit within a variety of vehicles. Proterra’s best-in-class battery systems have been proven through more than 20 million service miles driven by Proterra transit vehicles and selected by world-class commercial vehicle manufacturers to power construction equipment, delivery trucks, school buses, coach buses, and low-floor cutaway shuttles.
