SELECTIVE THERMAL MECHANIZATION FOR RESS HEAT LOADS

A method is usable for cooling portions of a vehicle having a plurality of low temperature radiators (LTR), a rechargeable energy storage system (RESS), an i-condenser coolant circuit, and a RESS coolant circuit. Cooling the RESS occurs by comparing ambient temperature to target low and high temperatures. If the ambient temperature is below the target low temperature, coolant flow is routed through a first flow path placing the first and second LTR in the RESS coolant circuit. If the ambient temperature is between the target low and high temperatures, coolant flow is routed through a second flow path placing the first LTR in the RESS coolant circuit and the second LTR in the i-condenser coolant circuit. If the ambient temperature is above the target high temperature, coolant flow is routed through a third flow path placing the first and second LTR in the i-condenser coolant circuit.
