Cummins has developed an electric mini excavator prototype powered by Cummins BM4.4E flexible battery modules (4.4 kWh each). The 3.5-ton excavator prototype is designed to support a full work shift and charge in under three hours.
The excavator contains eight BM4.4E modules connected in a series configuration to provide a total energy of 35 kWh. Mounted near the base of the excavator, the Cummins-designed and built battery modules utilize Li-ion technology to achieve a higher energy density and proprietary control technology to maintain the battery state-of-charge for a longer zero emission range. The modular design also allows for scalability to other applications and duty cycles.
“Our strategy is to develop diversified, dependable power solutions. We look forward to continuing to partner with companies to design and test the construction industry’s latest technologies,” said Julie Furber, vice president – electrified power, Cummins.
