SEG Automotive Range Extender – Efficient power generation on demand powerful

As electromobility expands to a wider range of use cases, the limitations of pure battery-electric solutions become more apparent – especially in demanding applications like long-haul transport, off-highway machines or in markets with limited charging infrastructure. This is where range extenders offer a decisive advantage: using a compact internal combustion engine to generate electricity while driving, they recharge the high-voltage batteries on the go and significantly increase the vehicle’s reach and operational flexibility.

SEG Automotive offers customized, highly efficient and fully integrated motor-generators for range extender vehicles. Based on decades of experience of designing and industrializing hyper-efficient and reliable e-machines, our system delivers reliable performance in an ultra-compact design.

With SEG Automotive’s range extender solutions, you gain a robust and future-proof power generation solution that bridges the gap between zero-emission ambitions and real-world mobility needs.
