Continental supplies powertrain for Renault’s e-car Zoe
The externally excited synchronous motor delivers a continuous output of 43 kW (65 kW peak) and a torque of 220 Nm. Differential and transmission are integrated – which experts say is ideal for battery electric vehicles since it achieves high efficiency across the entire operating range and quickly delivers high power levels. The electric motor gets by without rare earth metals; instead, it uses copper coils in stator and rotor. As a result, it can be used either as a motor (for driving the vehicle), as a generator (for charging the battery while driving) or as a transformer (for external charging at the mains). The powertrain is provided as a modular system, enabling cost-effective solution.
Also the power electronics are implemented as a modular system. In the ZOE, Renault installs the second generation of Continental’s e-car power electronics unit, which features significantly lower size and higher power density than its predecessor.
Besides the power train, Renault also picked further electronic components from Continental. These include the airbag control unit, side and front sensors, wheel speed sensors, the audio system and the keyless access system.
