Liquid Cooling MCU and Motor 

The Electric Vehicle Driveline package requires a liquid-cooling system. The recommended liquid-cooling setup 
is shown in 

Figure 4.1 

below. 

 

Figure 4.1: Recommended Liquid Cooling Setup 

4.1

 

Coolant Loop Requirements 

 

CAUTION 

The coolant should never run in parallel paths. The coolant hoses between the 
controller and the motor should be in series, as the thermal algorithms used in the 
software depend upon the coolant flowing at the same rate through both 
components. 

 

 

CAUTION 

The coolant loop for the transmission MUST be on a SEPARATE coolant loop than the 
MCU and Motor.
