Cummins put Meritor’s 17Xe ePowertrain on truck (the one we saw in Hannover, last year), using a test truck to evaluate its performances. The test was carried out at Millbrook Proving Ground in Bedfordshire, England. The ePowertrain was developed by Meritor, now fully controlled by Cummins, with Advanced Propulsion Centre (APC) consortium partners Danfoss’ Editron division and Electra.

Cummins ePowertrain: some technical details

More into technical details, Danfoss’ Editron division developed and supplied the high-power electric motor and high-efficiency silicon carbide inverter powering the axle. The electric motor will be based on a patented architecture and thermal management methodology exceeding the APC’s 2035 Roadmap targets for power density. As a result, only one motor will be required in the electric powertrain design, marking a significant step forward for the industry, as current alternatives usually need two motors to meet this product segment’s power requirements.

Additionally, with output capabilities of 430 kW continuous power, the integrated 17Xe ePowertrain will power heavy-duty trucks and buses in 6×2 or 4×2 configurations. It is available in a range of ratios and with three-speed transmission capabilities.

We’re excited to showcase the capabilities of the 17Xe ePowertrain,” said John Bennett, General Manager – ePowertrain at Cummins. “The compact, integrated design and power density are ideal for OEMs interested in developing future-proof, sustainable heavy-duty equipment. We look forward to working with our customers to accelerate decarbonisation of the heavy-duty vehicle market.”
