Daimler Trucks will be using a globally uniform basic architecture for all-electric trucks: the ePowertrain. The ePowertrain will be the technological basis of all medium- and heavy-duty CO2-neutral, all-electric series-produced trucks from Daimler Trucks – whether powered purely by batteries or by hydrogen-based fuel cells.
The technological heart of the ePowertrain is the integrated electric drive, eDrive. This is used in the form of an e-carrier concept, i.e., an e-axle with one or two integrated e-motors including transmission.
The eDrive is an in-house development by Daimler experts and offers numerous advantages over concepts with one central motor. For example, the more compact design allows a larger space to install a larger battery with a higher capacity, which has a positive effect on range. The high battery capacity ensures high power transmission to the e-axle, thus allowing continuous power delivery. The recuperation potential increases due to the combination of a large battery with very powerful e-motors.
The eDrive is to be applied in various vehicles at Daimler Trucks in the medium- and heavy-duty segment worldwide – whether with purely battery-electric or hydrogen-powered fuel-cell drive. The eDrive is designed as a drive family consisting of different variants, the first of which will have its premiere in the series-produced version of the Mercedes-Benz eActros. Within a modular system, the eDrive can be tailored to suit the market, segment and vehicle type.
A modular ePowertrain will facilitate synergies with technology developments for different markets and segments, as well as economies of scale on account of the use of uniform components. This, in turn, results in competitive costing.
In addition, a high proportion of components will be taken from conventional powertrains, which is expected to contribute to competitive development and production costs.
