Abstract
A temperature management apparatus for managing the temperature of cells, which includes an air intake duct, a fan unit, a first temperature detector (temperature sensors, a temperature detecting part) for detecting temperature Tb of the cells, a second temperature detector (a temperature sensor, a temperature detecting part) for detecting ambient temperature Ta, and a control device. The fan unithas a fanand a motor. The control devicehas a storage partand a deciding part. The storage partstores a cooling-necessitating temperature Tc and a heating-necessitating temperature Th. The deciding partdirects the fan unitto drive the fanin a case where the temperature Tb of the cells becomes equal to or higher than both the temperature Ta of the air and the cooling-necessitating temperature Tc, or in a case where the temperature Tb of the cells becomes equal to or lower than both the temperature Ta of the air and the heating-necessitating temperature Th.
