With a permissible gross weight of 26.0 t the Mercedes-Benz Electric Truck produces zero local emissions and runs silently, yet it is equal to a truck with an internal combustion engine in terms of load and performance, Mercedes says.
The features of the Mercedes-Benz Electric Truck include its drive with electrically powered rear axle and electric motors directly adjacent to the wheel hubs. Their maximum output is 2 x 125 kW, while torque is 2 x 500 Nm.
The battery capacity of the Mercedes-Benz Electric Truck has a modular design. The basic arrangement is a battery pack consisting of lithium-ion batteries with a total capacity of 212 kWh. This results in a range of up to 200 km which should normally be enough for a typical day’s delivery round, Mercedes says.
Interconnected system
The Mercedes-Benz Electric Truck uses the possibilities opened up by connectivity to create en interconnected system that incorporates range and load management, vehicle information and peripheral data. It starts with the scheduling: instead of the conventional fixed delivery runs there is a flexible system. It ensures that all the planned haulage work can be completed by the vehicle fleet without overextending or underutilising the range of the trucks.
Of course, when on the road there can always be unforeseen events, such as a road closure, which could bring the truck to the limits of its range. In this case the “Intelligent Range Management” Mercedes developed, immediately intervenes: It can either switch from the “auto” to the “eco” drive mode to maximize the range or schedule an additional battery charging at a delivery stop, Mercedes says. For the driver this provides certainty, because he or she will always reach his or her destination no matter what happens, according to Mercedes.
The power supply, the energy tariffs and the correct charging strategy are important factors for the overall economy of electric trucks, Mercedes says. Daimler ensures it determines the most economical solution for every application. For example, depending on individual circumstances, stationary battery storage units from Mercedes-Benz Energy GmbH can further improve economic efficiency and enable quick recharging without overloading the power supply, they say. The storage units consist of lithium-ion batteries, and the capacity can be adapted individually to the requirements of the fleet.
