The Auxiliary 4-in-1 Integrated Controller is a compact and highly integrated control platform designed for modern commercial electric vehicles. It consolidates multiple auxiliary power and drive control functions into a single unit, simplifying system architecture while improving reliability, efficiency, and overall vehicle integration.
In traditional commercial EV architectures, auxiliary systems such as compressors, pumps, and low-voltage power supplies are typically managed by separate controllers. This increases wiring complexity, installation space requirements, and system coordination challenges. The 4-in-1 controller addresses these issues by integrating key auxiliary functions into a unified control module, allowing vehicle manufacturers and integrators to streamline electrical system design and reduce component count.
The controller includes a high-efficiency high-voltage to low-voltage DC/DC converter, which converts the vehicle’s high-voltage battery power into stable low-voltage electricity required by auxiliary equipment and vehicle electronics. This ensures reliable power supply for control units, sensors, lighting systems, and other onboard components.
In addition to power conversion, the system provides dedicated drive control for auxiliary devices commonly used in commercial vehicles. The integrated electric air compressor drive control manages compressor operation for braking systems, suspension systems, or other pneumatic applications. Meanwhile, the electric oil pump drive control supports lubrication and cooling functions within electric drivetrains or other vehicle subsystems, ensuring stable operation under varying load conditions.
The platform also features integrated auxiliary power distribution and control logic. This centralized management allows multiple auxiliary components to be coordinated through a single controller, improving communication efficiency between subsystems and enabling more precise operational control. By reducing the number of separate controllers and wiring harnesses, the system helps lower vehicle weight and simplify assembly.
Designed with flexibility in mind, the Auxiliary 4-in-1 Integrated Controller is compatible with a range of external compressor and pump systems from different manufacturers. This allows vehicle developers to select auxiliary components that best match their application requirements while maintaining a standardized control interface.
The solution is particularly suitable for electric buses, electric trucks, logistics vehicles, sanitation vehicles, and other special-purpose commercial EV platforms. By integrating several auxiliary functions into one reliable module, the controller helps improve system efficiency, reduce installation complexity, and enhance long-term operational stability for commercial vehicle programs.
