Abstract

A battery cooling system includes: a cooling circuit; a power transmission device disposed in the cooling circuit, the power transmission device including a gear; a drivetrain oil having an electric insulating property and being used for lubrication of the gear, the drivetrain oil circulating in the cooling circuit; a battery unit disposed in the cooling circuit, the battery unit including a module case that houses a plurality of battery cells; a pump disposed in the cooling circuit; and a radiator disposed in the cooling circuit, the radiator releasing heat from the drivetrain oil flowing in the cooling circuit. The drivetrain oil performs direct heat exchange inside the power transmission device and flows through an inside of the module case and performs direct heat exchange with the battery cells.
