Abstract
The present invention provides a battery temperature control system having a simple configuration and capable of immediately raising a battery temperature by actively using heat generated by an internal combustion engine. The battery temperature control system includes: an engine cooling circuit in which a coolant in an internal combustion engine is circulated between a coolant jacket and a radiator by a coolant pump; an exhaust heat recovery circuit in which a coolant in an EGR cooler that recovers exhaust heat of the internal combustion engine flows; a battery cooler-destined branch circuit that is branched from the engine cooling circuit and goes toward an upstream side of the battery cooler in the battery cooling circuit; and a channel switching mechanism that selectively connects a downstream side of at least one of the exhaust heat recovery circuit or the battery cooler-destined branch circuit to the upstream side of the battery cooler in the battery cooling circuit.
