Document Type and Number:
Japanese Patent JP7295155
Kind Code:
B2
Abstract:
A battery cooling system includes: a battery cooling circuit in which a heating medium that cools a battery circulates and include a cooler path and a battery path; a cooler that cools the heating medium; the battery; a combined cooling circuit; a switching valve configured to selectively allow and cut off communication between at least two paths selected from the cooler path, the battery path, and the combined cooling circuit; a heating medium temperature sensor that detects a temperature of the heating medium; an environment temperature sensor that detects a temperature of the environment; a battery temperature sensor that acquires a temperature of the battery; and a control device. The control device determines whether there is an abnormality in the switching valve based on the heating medium temperature and a threshold temperature that is associated with a maximum temperature out of the environment temperature and the battery temperature.
