The present invention provides a battery electric vehicle and method to a cool high voltage powertrain component of a battery electric vehicle. The battery electric vehicle includes a passenger cabin,a refrigerant circuit adapted to cool the passenger cabin, a powertrain including a high voltage powertrain component, a coolant circuit adapted to cool the high voltage powertrain component and a control module. The refrigerant circuit includes a condenser and an evaporator. The coolant circuit includes a radiator downstream from the condenser. The control module is configured to recirculate cabin air to the passenger cabin in response to data indicating temperature of the high voltage powertrain component exceeds a predetermined threshold temperature in order to reduce the air outlet temperature at the condenser and the air inlet temperature at the radiator. A related method to cool a high voltage powertrain component of a battery electric vehicle is also disclosed.
