Proterra和小松已达成协议，利用Proterra的电池技术开发小松的首款电池动力的中型液压挖掘机。

此次合作代表了Proterra进入越野车市场以及该公司的第一台电池动力的电动建筑设备。

小松将利用Proterra的高性能电池系统在2021年开发电动挖掘机，然后在2023年至2024年实现商业化生产。为电动挖掘机供电的Proterra电池系统将具有高能量密度和快速充电技术。

Proterra电池组在美国设计制造，利用业界领先的能量密度和可定制的设计来适合各种车辆。 Proterra电池平台的包装灵活性将进一步实现电池在中型挖掘机中的最佳位置，并取代用于平衡挖掘机液压臂运动的常规配重的需求。

Proterra首席执行官Jack Allen说：“Proterra很高兴与小松合作开发电池动力建筑设备。通过我们的运输车辆车队1600万英里行驶的测试，Proterra的一流电池技术得到了证明。我们期待着与小松公司合作，为全球更多社区提供零排放、安静的Proterra动力车辆。”

除了减少噪音和空气污染外，Proterra电池组的设计还为越野、安全和耐用性至关重要的建筑环境提供了理想的应用。 Proterra以安全为核心设计电池，所有Proterra电池组均经过严格的测试，以确保它们能够承受最严酷的条件，因此使其成为小松和越野车市场的理想选择。

Komatsu and Proterra collaborate to develop all-electric construction equipment

Proterra and Komatsu have made an agreement to leverage Proterra's battery technology for the development of Komatsu's first battery-electric mid-size hydraulic excavator.

The collaboration represents Proterra's entry into the off-road vehicle market and the company's first Proterra Powered battery-electric construction equipment.

Komatsu will utilize Proterra's high-performance 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.

"As more communities embrace a zero-emission future, Proterra is excited to partner with Komatsu to develop battery-electric construction equipment," said Proterra CEO Jack Allen. "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. We look forward to collaborating with Komatsu to deliver the benefits of emissions free, quiet Proterra Powered vehicles to more communities around the world."

In addition to reducing noise and air pollution, the design of Proterra battery packs offers an ideal appliCATion for an off-road, construction setting where safety and durability are of utmost importance. Proterra designs its batteries with safety as a core guiding principle and all Proterra battery packs undergo rigorous testing to ensure they can withstand the toughest conditions, making it an ideal choice for Komatsu and the off-road vehicle market.
