The invention discloses a vehicle-mounted battery pack temperature adjusting system, which is provided with a wind driven generator, a semiconductor refrigerator and a DC/DC converter, and is characterized in that an output circuit of the wind driven generator is connected with a vehicle-mounted charger; the vehicle-mounted charger is connected with the DC/DC converter; the DC/DC converter is connected with the semiconductor refrigerator; and the semiconductor refrigerator is connected with the power battery system and is used for adjusting the temperature of the power battery system. The invention further discloses a control method of the temperature adjusting system. By adopting the vehicle-mounted battery pack temperature adjusting system, the problem that the power battery system cannot be normally used in high-temperature and low-temperature environments is solved by combining vehicle-mounted wind power generation and thermoelectric refrigeration, so that the power battery systemis in the optimal working environment, the service life of the power battery pack and the whole vehicle under the limit working condition is prolonged, and the safety of the power battery pack and thewhole vehicle under the limit working condition is improved.
