Voith Expands E-Mobility Portfolio at IAA Transportation 2022

Voith is further expanding its expertise in the e-mobility sector for commercial vehicles. With the Voith Electrical Drive System (VEDS) and the Plug and Drive H2 storage system, the technology group is presenting two concepts at IAA Transportation 2022 that promote an economical and sustainable mobility shift for heavy-duty trucks and buses. “Alternative, sustainable drives are defining the discourse of the present and the technologies of the future. Even today, the result is an unprecedented variety of drive solutions. We are fulfilling these customer demands with a portfolio geared towards alternative drives,” says Martin Wawra, executive vice president and CEO Voith Turbo Mobility.

VEDS: E-mobility for buses and heavy-duty trucks

Since its introduction in 2019, Voith has continued to develop this electric drive concept, gaining a footing in ever more commercial vehicle segments. For buses, the portfolio consists of the HD (heavy duty) variant, which is particularly suitable for double-decker and articulated buses with its 340 kW IPMS motor. In addition, Voith offers an MD (medium duty) variant with an output of 260 kW, which is optimized specifically for solo buses and exclusively inner-city uses. Customers worldwide appreciate the outstanding efficiency of this system, which was recently confirmed by the independent UTAC institute. With an efficiency level of 0.69 kWh/km, the Wrightbus StreetDeck Electroliner is the most efficient e-double-decker in the world. The VEDS plays a significant role in this success.

The concept supports battery systems from a wide range of manufacturers and is also enabled for use in fuel cell electric vehicle drivetrains. Thanks to its compact design, the VEDS requires no additional installation space in chassis designed for combustion engines. It is therefore very easy to convert existing vehicle fleets with conventional diesel, hybrid or gas drives.

With the VEDS HD+, the company is also introducing its first drive concept for heavy-duty trucks. Special configurations for waste collection vehicles, inner-city logistics or long-distance transport applications ensure efficient driving with every use. The core of the system is a new innovative automated four-gear electric transmission. This makes optimal traction available for every driving situation and under any load condition. At the same time, it ensures that the electric motor is always operated at optimum efficiency. For the drive system of the VEDS HD+, customers can choose between two Evo-named electric motors with top outputs of 330 and 390 kW respectively. 

The VEDS HD, VEDS MD and VEDS HD+ meet the requirements of ISO 26262 (Automotive Functional Safety) and the new requirements of Automotive Cyber Security (ISO 21434). This internationally applicable standard protects the vehicle against external manipulations and ensures its functionality – by preventing unauthorized access to electronically controlled driving and braking systems, for example.
