Thermal Management

The hybrid/EV battery is cooled and heated with pre-mixed DEX-COOL®, which is a 50/50 mixture of DEX-COOL® and de-ionized water. A refrigerant/coolant heat exchanger (chiller) and the G1 A/C compressor cools down the high voltage hybrid/EV battery. A high voltage heater can also heat the coolant entering the hybrid/EV battery when needed. Thermal transfer occurs between the bottom of the Hybrid/EV Battery Modules and coolant plates that circulate the heated or cooled coolant.
