Abstract
A system for overcooling a drive motor and a method for controlling the same may include a first cooling loop in which a first coolant circulate, the first coolant being in a heat exchange with a power electronics (PE) part and a drive motor cooler mounted in the first cooling line and configured to cool cooling oil supplied to the drive motor fluidically connected to the drive motor cooler; a second cooling loop disposed independently from the first cooling loop, wherein a second coolant circulates in the second cooling loop, the second coolant being in a heat exchange with a battery module and a battery chiller mounted in the second cooling loop; and a switch unit configured to selectively shift a flow path of the second coolant such that the second coolant is in a heat exchange with the drive motor cooler.
