E-Force One, a supplier of 18-ton e-trucks, will begin equipping its vehicles with batteries from Swiss manufacturer ecovolta.
The batteries are part of a concept E-Force One developed to individually tailor each vehicle to the route type and distance it must travel, as well as the charging technology available. The e-truck maker can outfit each semi-trailer with different battery sizes and drive mechanisms customized for different trip profiles. The individual components are assembled into a singular package for each vehicle.
For example, E-Force One’s EF18 SZM is equipped with permanent magnet synchronous motors capable of outputting 440 kW or 550 kW of power, with a battery capacity between 105 kWh and 630 kWh. This combination allows the vehicles to reach speeds of up to 85 km/h and climb inclines of up to 16%.
ecovolta’s evoTractionBattery models are available with voltages ranging from 24 to 96 volts and capacities of 2.5 kWh to 15 kWh. Vehicle makers can connect up to 16 batteries in series and create parallel connections of up to 32 strings, enabling potential battery voltages of 24 to 829 volts. ecovolta says its batteries can offer energy density of up to 480 Wh per liter.
ecovolta CEO Pirmin Reichmuth said, “Commercial electric vehicles often have typical trip profiles for which their drivetrains and batteries can be optimized. One given type of vehicle may therefore require a different battery than its twin. Manufacturers who would like to optimally customize their products to users’ needs typically require modular battery solutions. At the same time, batteries still need to reach a level of standardization which maintains efficient product development and production.”
