Ourelectronic control products stand out for their modular design, high compatibility, and advanced technological integration. The battery management systems (BMS) cover 12V, 48V, 400V, and 800V full-voltage platforms, supporting both traditional hybrid and pure electric vehicles with precise energy management and safety protection. The electric drive lever, a flagship HMI product under our Preh brand, enables integrated control of acceleration, deceleration, steering, and autonomous driving modes, replacing traditional steering wheels to simplify cockpit interaction and enhance operational efficiency.
Safety is at the core of our innovation. The Pyrotechnic High-Voltage Disconnector (PBD), a CLEPA Innovation Award-winning product, can cut off high-voltage circuits within milliseconds, protecting occupants and first responders during emergencies. Our electronic control units (ECUs) serve as the “brain” of vehicle systems, integrating seamlessly with ADAS, cockpit domain controllers, and V2X connectivity to support L2-L4 level autonomous driving functions.
Dowway’s electronic control solutions are trusted by global automakers including Volkswagen, BMW, Mercedes-Benz, BYD, NIO, and Xpeng. We combine hardware excellence with flexible software customization—supporting multiple chips, hypervisor virtualization, and various operating systems—to provide tailored solutions that accelerate the transformation of the automotive industry towards electrification, intelligence, and safety.
