The German company, world leader in transmissions, has developed two units that can be easily integrated with platforms and electric motors in circulation to eliminate refueling anxiety
The second youth of Range Extender. Ended up in the forgetary downstream of the pioneering age of electric carthey are returning to fashion to offer a remedy to what continues to be also one of the main brakes in 2025 to the spread of zero emissions mobility: autonomy anxiety. If Mazda He chose to dust off the Wankel to increase the maximum travel of the MX-30 R-EV, the German company Zf will propose two solutions that starting from 2026 they will offer their contribution to increase the range of electric action. A return to the scene son of technological progress of the last 15 years, which today allows the creation of more compact, powerful and efficient units than the solutions, then futuristic, sported by models such as BMW i3 or Chevrolet Volt. The growing demand for electric vehicles with Range Extender – the so -called Reev, Range Extended Electric Vehicles – does not come from European countries with infrastructure deficiencies for charging, but from the homeland of electric mobility: the China. Despite being very widespread in large centers and main road arteries, in fact, the distribution of the Chinese charging network is not homogeneous. Which makes the supply to millions of people complicated, distributed in one of the largest countries in the world.

The two devices developed by ZF are called era and era+. The first, consisting of an electric motor with an integrated inverter, a planetary reducer and dedicated software, delivers from 95 to 150 HP (from 70 to 110 kW) depending on the configuration. THE’era+ it reaches up to 203 hp (150 kW) and adds a clutch with differential, which allows use both as a current generator and as a driving unit. Both are compatible and easily integrated on 400V or 800V architecture and with most electric motors today around. “Although the autonomy of electric cars is growing and has reached the average of 500 kilometers – so Otmar Scharrervice -president senior Research & Development by ZF Electrified PowerTrain Technology -, autonomy anxiety still influences one wide range of potential buyers in choosing the vehicle. Range extenders represent a real alternative to larger batteries, and therefore more expensive, or to plug-in hybrids “.
