1. A battery temperature regulating apparatus to be applied to a vehicle, the battery temperature regulating apparatus comprising:
an onboard battery;
a temperature regulating plate configured to allow heat exchange between the onboard battery and a first heat medium flowing into the temperature regulating plate;
a heat exchanger;
a first passage configured to guide the first heat medium flowing out of the temperature regulating plate to the heat exchanger;
a second passage configured to guide the first heat medium flowing out of the heat exchanger to the temperature regulating plate;
a third passage configured to branch off the first passage at a branch point and join the second passage;
a radiator disposed in the third passage;
a valve capable of opening and closing the first passage on a side of the branch point closer to the heat exchanger and capable of opening and closing the third passage on another side of the branch point;
a first temperature sensor configured to detect a temperature of the first heat medium flowing through the first passage; and
a control device,
wherein the heat exchanger comprises
a container configured to accommodate a heat source that does not use a power supply for the vehicle, and
a first internal passage disposed around the container in such a way as to allow heat exchange, the first internal passage being configured to allow the first passage to communicate with the second passage;
the control device comprises
at least one memory, and
at least one processor coupled to the at least one memory and configured to execute a process in cooperation with a program included in the at least one memory; and
the process comprises
determining whether a temperature of the onboard battery is higher than an upper threshold of a proper temperature range,
determining whether the heat source is mounted in the container at least on a basis of the temperature of the first heat medium detected by the first temperature sensor, and
in a case where the temperature of the onboard battery is determined to be higher than the upper threshold and that the heat source is mounted in the container, controlling the valve in such a way as to allow the first heat medium to flow through the heat exchanger.
