Voith to show latest electric drive and H2 storage systems at IAA Transportation


Voith will present two products at IAA Transportation 2022 in September that promote an economical and sustainable mobility shift for heavy-duty trucks and buses: the latest Voith Electrical Drive System (VEDS) and the Plug & Drive H2 storage system.

VEDS. Since introducing it in 2019, Voith has continued to develop its electric drive system, gaining a footing in 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 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 VEDS concept supports battery systems from a wide range of manufacturers and is also enabled for use in fuel-cell-electric vehicle drivetrains. Due 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, innercity 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.

Plug & Drive H2 storage system. Customers receive everything from a single source, from the tank nozzle to the fuel cell inlet, including a patented installation system to accommodate the hydrogen tanks. Voith uses pre-impregnated fibers, so-called TowPregs, as material for the tanks, which Voith manufactures itself.


The production utilizes a special winding process that enables optimized winding layers. This enables higher storage amounts of H2 without any compromises in terms of safety, even with high pressures in the tank. Here Voith focuses on 700 bar technology to ensure long ranges even with limited installation spaces. Combined with short refueling times—it takes about ten minutes for full refueling—this results in greater economic efficiency for the operator, compared to conventional systems.

The Plug & Drive H2 storage system is primarily designed for heavy-duty commercial vehicles, construction vehicles and similar applications, where the use of battery-electric concepts does not make sense from an economical or technical perspective. Voith also ensures sustainability and recyclability throughout the entire lifecycle.
