ZF announces new central e-drive for commercial vehicles in China

The new electric central drive will be manufactured entirely in China

ZF has joined China’s efforts to electrify its public transport and distribution logistics by supplying a new electric central drive for buses and medium-duty trucks.

The new unit was developed in China by a local ZF development team to meet the specific requirements of the Chinese market in terms of safety, performance and cost-effectiveness. It is designed for city and shuttle buses with a length of 10-12 meters as well as medium-duty trucks up to 12 tonnes. In addition, the electric drive meets all the necessary standards for integration into established vehicle platforms.

The unit is driven by a permanent magnet synchronous motor (PSM). It is highly efficient at low speed range, making it particularly suitable for stop-go traffic typical of urban areas, while enabling greater range per battery charge. With an output of 170 kW, peak torque of 3000 Nm and a maximum climbing capacity of approximately 15% (bus) or 25% (truck), demanding topographies can be easily overcome with the new drive. Production is anticipated to commence in China in 2020.

In addition to the unit itself, ZF will also be able to supply inverters and control units including the appropriate software. This guarantees optimum efficiency between battery and drive and reduces testing and homologation costs for the manufacturer. The system is designed to fulfil international functional safety standard (ISO26262) with level at ASIL-C.
