BG-AUX-EHPS-HVC is an advanced Electric Hydraulic Power Steering Pump (EHPS) featuring an integrated high-voltage controller or ECU within a single compact unit. Designed specifically for commercial electric vehicles, including electric trucks, buses, shuttle vehicles, and specialty commercial platforms, the system eliminates the need for a separate steering controller, reducing wiring complexity and installation costs.

Supporting voltage ranges from 240VDC to 750VDC, BG-AUX-EHPS-HVC is compatible with both medium- and high-voltage commercial EV architectures. The integrated control system enables precise speed and pressure regulation, ensuring smooth steering performance across varying road conditions and vehicle loads.

With a compact design, wide operating temperature range from -40°C to +85°C, and optimized hydraulic efficiency, BG-AUX-EHPS-HVC helps OEMs simplify vehicle integration while improving system reliability and reducing total component count.
