Coolant - Electric Drive



HYBRID/EV BATTERY PACK COOLING SYSTEM, POWER ELECTRONICS COOLING SYSTEM

The hybrid/EV battery pack cooling and electronics cooling systems circulate a pre-mixed DEX-COOL which is a 50/50 mixture of DEX-COOL and de-ionized water. De-ionized water is required for high voltage isolation and to prevent corrosion from effecting heat sink performance. Always use pre-mixed coolant and never use tap water in the battery and electronics cooling systems.
