Virtual Validation of an Electric Coolant Pump for ICE and BEV Vehicles

Buehler Motor demonstrates how virtual prototypes validate HW and SW functions for its coolant pump technology which includes centrifugal and screw designs with custom software for protection and communication, enhancing performance and reliability.

Coolant pumps are essential components in both internal combustion engine (ICE) and electric vehicle (EV) cooling systems, maintaining optimal temperatures for various vehicle systems. In ICE vehicles, these pumps circulate coolant to regulate engine and charge air temperatures, preventing overheating and improving combustion efficiency to meet emission standards. In EVs, they manage the thermal conditions of batteries and power electronics, enhancing reliability and extending the lifespan of components. Buehler Motor's coolant pump technology features both centrifugal and screw pump designs, with power ranges from 20W to 450W.

These pumps include custom software functions for self-protection, vehicle communication, and emergency modes. A virtual prototype can serve as an executable spec to test and validate these various hardware and software functions and modes within system level applications. ROI of simulation also extends to examination of statistical variations of pump performance in face of what-if system disparities. Buehler pumps are precisely engineered to meet specific customer requirements, incorporating BLDC motors, sensors, control electronics, and software.
