ZF, a leading global automotive parts supplier, recently released a new range-extending system, dedicated to providing innovative solutions for the field of electric mobility. The systems released this time include the electric drive range-extending system (eRE) and the electric drive range-extending drive system (eRE+). These two systems adopt a highly integrated design, integrating the motor, integrated inverter, adaptation software and planetary gear set. The eRE+ version further integrates the intelligent clutch and differential on this basis, which can not only serve as a power generation device, but also provide a second drive system.
Both the eRE and eRE+ systems support 400-volt and 800-volt voltage architectures to meet the needs of different models. The output power range of the eRE system is 70-110 kilowatts, while the eRE+ can reach 70-150 kilowatts and supports four-wheel drive. Compared with traditional plug-in hybrid systems, ZF's range-extending system has significant advantages in terms of cost, R&D cycle and platform development investment, and simplifies supply chain management, providing a more attractive solution for car companies that have just entered the field of electric vehicles.
The system can effectively solve the "range anxiety" of electric car owners. When the battery power is lower than a certain value, the internal combustion engine will start to generate electricity to charge the battery to ensure that the vehicle's endurance is not limited. Especially in areas with imperfect charging infrastructure, the range-extending system can provide a comprehensive endurance of more than 700 kilometers through the combination of batteries and range extenders.
ZF's range-extending system optimizes thermal efficiency through a dual-mode "power generation + drive" design. The internal combustion engine always works in the best fuel efficiency range, and carbon emissions are reduced by 15% compared to traditional plug-in hybrid systems. This system can not only save 30% of the powertrain development cost, but also shorten the R&D cycle by 6 months, which is particularly suitable for new forces car companies and areas with fewer charging facilities.
As the demand for extended-range electric vehicles in the Chinese market grows, ZF's all-new extended-range system will be put into mass production in 2026 and is expected to promote the development of this field. Currently, three Chinese automakers have entered the joint testing phase, and the first model equipped with the system is expected to debut in the third quarter of 2026.
