Proterra, an electric vehicle technology manufacturer, and Komatsu, a construction equipment manufacturer, have entered into an agreement to leverage Proterra’s battery technology for the development of Komatsu’s first battery-electric middle class hydraulic excavator.
Komatsu will utilize Proterra’s battery systems for the development of a proof-of-concept electric excavator in 2021 before expected commercial production in 2023 to 2024. The Proterra battery system powering the electric excavator will feature high energy density and fast charging technology.
Engineered and manufactured in the U.S., Proterra battery packs leverage industry-leading energy density and a customizable design to fit within a variety of vehicles. The packaging flexibility of Proterra’s battery platform will further enable the optimal placement of the batteries within the middle class excavator and replace the need for a normal counterweight used to balance the excavator’s hydraulic arm movements.
“Proterra’s best-in-class battery technology has been proven in 16 million miles driven by our fleet of transit vehicles. What’s working in our battery-electric transit vehicles on roads across North America can work off-road, too,” said Proterra CEO Jack Allen.
Proterra battery systems are used by OEMs to introduce 100% battery-electric vehicles, including electric school buses, coach buses, delivery vans, and low-floor cutaway shuttle buses.
