Boosting all-electric truck performance
Managing power is central to the success of many of those represented at The Battery Show Europe, and visitors will be able to learn at the next show how the PD400 inverter from John Deere Electronic Solutions (JDES) is being used as a key component in the FUSO eCanter all-electric truck.
The JDES PD400 is a rugged, off-the-shelf inverter that has been proven in use at John Deere and in other off-road OEM applications. The flexible PD400 software provides a broad set of features and tunings that allow the eCanter electric drive system to optimise efficiency and performance.
The eCanter requirements demanded very high peak torque under difficult operating conditions. In response, JDES completed a detailed drive cycle analysis that incorporated the thermal characteristics of the inverter. The result was a software upgrade that increased boost currents to 50% above previously rated limits for short periods of time, all while maintaining reliability goals.
JDES resources were also used in the execution of ECE-R85 electric powertrain homologation testing. The traction motor, PD400 inverter, and the reference vehicle cooling system were assembled at JDES labs in Fargo, North Dakota, USA. The 30-minute power test and the net power test were witnessed by a third party to validate applicable torque and power claims for the eCanter.
“Working with FUSO on the global eCanter project is very exciting,” says David Gordon, Business Development Manager at JDES. “A cooperative nature and commitment to success is what we have in common.”
Lars Schroeter, Head of xEV Powertrain Systems for FUSO, commented: “We sought out John Deere as an inverter supplier from their reputation for quality and integrity. After working with JDES we certainly see they deliver to this promise.”
FUSO’s all-electric eCanter light-duty truck is produced at the company’s plants in Tramagal (Portugal) and Kawasaki (Japan). The eCanter has a range of 100 kilometres and a load capacity of two to three tons – depending on body and usage. The vehicle’s electric powertrain contains six high-voltage lithium ion battery packs with 420V and 13.8kWh each.
JDES is a company with a strong technological focus and extensive engineering design capabilities. It has engineers engaged in over 80 active projects. It also has extensive experience in product design, product test, manufacturing, and support services. This enables it to handle any and all aspects of providing solutions to industries that require quality electronics that operate in harsh or extreme environments.
