1. A battery temperature adjustment system comprising:
a battery configured to store electric power from an external power source, and supply electric power to a motor as a drive source of a vehicle;
a cooling device to which the electric power from the external power source and the electric power from the battery are selectively supplied and configured to cool the battery; and
a control device configured to control the cooling device to adjust a state of charge of the battery and a battery temperature, wherein:
the control device stores a deterioration sensitivity map in which a deterioration sensitivity is preset according to the state of charge and the battery temperature, or is configured to calculate a deterioration sensitivity according to the state of charge and the battery temperature; and
to operate the cooling device when the vehicle is connected to the external power source, the control device is configured to select between the electric power from the battery and the electric power from the external power source based on the deterioration sensitivity.
