The invention relates to the technical field of automobile heat circulation, in particular to an air conditioning system with battery heating and cooling functions. The system comprises a cooling circulation pipeline, a heating circulation pipeline, a battery water circulation pipeline, an HVAC device, a first heat exchanger and a second heat exchanger. The battery water circulation pipeline is used for heating or cooling a battery; the battery water circulation pipeline is connected with the heating circulation pipeline through the first heat exchanger; the battery water circulation pipelineis connected with the cooling circulation pipeline through the second heat exchanger, the cooling circulation pipeline is connected with an evaporator of the HAVC device through an electromagnetic valve, the heating circulation pipeline is connected with a warm air core body of the HAVC device, and an electronic expansion valve is arranged between the second heat exchanger and the cooling circulation pipeline. In the charging state or in the driving process, the battery heating and cooling functions can be achieved, and the passenger compartment heating and cooling functions can also be achieved.
