Abstract

The invention discloses a thermal management system for a battery and a control method thereof, and an air-conditioning system of a vehicle. The thermal management system for the battery comprises a first heat storage device, which comprises a phase-change material packed in the first heat storage device and is internally provided with a battery pack; a circulation pipeline, which is internally provided with a heat exchange medium; a heating device, which is used for heating a heat exchange medium in the circulation pipeline; a heat dissipation device, which is used for heat dissipation of theheat exchange medium in the circulation pipeline; a heat exchange container, which is used for storing the heat exchange medium; and a circulation pump, which is arranged in the circulation pipeline,located between the heat exchange container and the first heat storage device, and used for circulating the heat exchange medium. According to the invention, the first heat storage device utilizes the phase-change material for heat storage; when the temperature of the heat exchange medium is too high or too low, heating and heat dissipation can be respectively performed by the heating device or the heat dissipation device, so the temperature of the battery pack is maintained constant, the service life of the battery pack is prolonged, and the thermal management efficiency of the battery packis improved.

Description

technical field [0001] The invention relates to the technical field of battery thermal management, in particular to a battery thermal management system, a control method thereof, and a vehicle air conditioning system. Background technique [0002] Batteries are one of the core components of electric vehicles or hybrid vehicles, and their performance directly affects the performance of electric vehicles or hybrid vehicles. For example, the power battery pack used in electric vehicles will generate heat during its charging and discharging process, which will increase the overall temperature of the battery pack, and if the temperature is too high, it will seriously affect the performance and life of the battery, and even directly cause the battery to fail. On the one hand, when charging and discharging, the heat dissipation or uneven heat release of each battery pack module will cause the battery to fail, and the battery with a local high temperature will age faster, and its lo...
