March 16, 2023 -- Coming soon to North America and featured in the Komatsu booth will be the 20-ton PC210LCE electric excavator, first displayed last fall at Bauma. Featuring Proterra’s lithium-ion battery technology, the excavator has 451 kWh of battery capacity, for up to 8 hours of operating time.*

For quiet and simpler operation without vibrations and zero emissions, the PC30E electric mini excavator fits the bill. Equipped with a 35-kWh battery and a 17.4 kW electric motor, its batteries can be fast-charged. This electric mini-excavator is suitable for a diverse range of workplaces including operating indoors, urban construction, and landscaping.

Komatsu will also feature its PC01E electric micro excavator powered by portable and swappable mobile batteries. Developed jointly with Honda, this new machine is designed for confined spaces in landscaping, agriculture and construction. Komatsu's vision for the swappable battery system is to scale up the technology for use in larger micro excavator models. 

The PC210LCE, PC30E and PC01E will be available in select markets in 2023.

Electric wheel loader concept

With a chassis based on the Komatsu WA70 wheel loader, the WA Electric wheel loader concept machine was developed in partnership with Moog Inc. Utilizing an "intelligent electrification system,” this wheel loader features an electric traction motor, lift, tilt and steering cylinders, power electronics, system control computer, battery and battery management system. 

Battery technology and charging station advancements

To provide flexible charging solutions for varying applications and customer needs, Komatsu is exploring high-power-charging solutions and developing multiple power source options including batteries. Three types of charging infrastructure options will be on display at the company’s booth.

Komatsu Generation 2 charger

The Komatsu Generation 2 charger is well-suited to adapt to varying site conditions, stepping voltage up or down to meet charging needs. With an input range from 400-1140V and an output of 300-900V, it features a universal CCS (AC/DC) charge plug and it too is transportable.

Developed in partnership with Proterra, the Proterra portable charging concept is designed for use in “off grid” locations or where site power is inaccessible or unreliable. 

The Komatsu energy container concept for mini-excavator

exhibited as a charging solution concept for environments without a power supply, is compactly designed for easy transportation. In addition to charging mini-excavators, it can also be used to charge other electric equipment on the work site.
