The headline from a recent Transport Topics article reads, “Extreme Temps Affect Electric Truck Batteries.” Only one brand, FUSO, enters its third winter season with customers operating the all-electric FUSO eCanter trucks. What FUSO learns daily from its customers continues to shape the future of electric trucks, regardless of the weather.
With its eCanter, FUSO is the industry’s first OEM to offer series produced all-electric trucks. FUSO electric trucks are operating today in various climates in the U.S., Japan and multiple European cities. In fact, FUSO recently celebrated the 1 millionth kilometer (or over 620,000 miles) in customers operations. This actual customer driven operational success allows FUSO to understand the true impact of hot and cold weather as it may affect the truck’s range. The Daimler engineers are collecting this data and customer feedback on a daily basis and reviews vehicle operation, route profiles and charging characteristics. This information flows back to Daimler’s eMobility Development Team as they design the next generation FUSO eCanter and other electric truck products.
Already, FUSO has conducted multiple winter tests of the eCanter, with a series of evaluations having taken place last February in Michigan. The eCanter uses six high-voltage lithium-ion batteries. Two are centrally located in the frame right behind the cab and two more on each side of the frame. Each are water-cooled providing longer service life and higher efficiency. To minimize the impact of the driving range in colder temperatures, the eCanter uses a heated water circuit for each high-voltage battery that helps to maintain a consistent operating temperature, minimizing the impact on driving range.
Each battery provides 420 V and 13.8 kWh or 82.8 kWh total. The electric truck uses a permanent synchronous magnet electric motor that yields an impressive output of 1850 kW and torque of 380 Nm. Power is transferred to the rear axle by a standard single-speed transmission. During the winter testing, the FUSO engineering teams had no issues when operating the eCanters in cold weather with the exception of a slightly shorter range, which echoes the comments in the Transport Topics article. The eCanters’ typical range based on body, load and usage is around 60 to 80 miles.

FUSO is excited to learn more about real-world eCanter operation as customers continue to use these electric trucks in this winter’s cold, rain, and snow. This practical experience is helping us build the next generation eCanter that’s on the horizon. Customers interested in the eCanter should contact email@example.com for more information.
