Extreme Temperature Validation: EV Bronco’s Battery and Cabin Cooling

The EV Bronco’s thermal management system performed effectively in extreme hot-weather testing in Death Valley. Using a water-to-refrigerant heat exchanger (chiller) for battery cooling and an air-to-refrigerant heat exchanger for cabin cooling, the system maintained safe uniform battery temperatures even during charging and a rigorous 16-mile drive with a 5,000-foot elevation gain at 40°C. This testing validated the thermal management system's mechanical components, including several in-house designs, and provided insights for future control system improvements.
