1. A control device controlling an electric compressor included in a refrigeration cycle for circulating a secondary refrigerant for cooling of cooling water that exchanges heat with a battery, the control device comprising:
an acquiring part that acquires a temperature of a battery cell of the battery;
an identifying part that identifies a charge amount of the battery; and
a cooling control part that determines a cooling-onset battery cell temperature on a basis of the charge amount identified by the identifying part, and operates the electric compressor to begin cooling the cooling water with the secondary refrigerant, on condition that the temperature acquired by the acquiring part is higher than the determined, cooling-onset battery cell temperature, wherein
when the identifying part identifies a first charge amount, the cooling control part determines the cooling-onset battery cell temperature that is higher than in a case where the identifying part identifies a second charge amount that is higher than the first charge amount.
