The invention provides an efficient waste heat utilization heat pump system and a control method thereof. The efficient waste heat utilization heat pump system comprises an electric compressor, a water cooling condenser, an outdoor heat exchanger, a check valve, a battery cooling plate heat exchanger and a gas-liquid separator which are sequentially and circularly connected through a pipeline. The pipeline between the outdoor heat exchanger and the water cooling condenser is connected with the pipeline between the check valve and the battery cooling plate heat exchanger through a parallel pipeline, and the pipeline between the outdoor heat exchanger and the check valve is connected with the gas-liquid separator through a pipeline; the heat pump air conditioning system has the following beneficial effects that the defects that an existing heat pump air conditioning system is narrow in operation boundary and low in low-temperature energy efficiency ratio are overcome; the invention also solves the problems of low-efficiency heat exchange only through temperature difference, limited operation condition and use scene limitation of battery heating only through motor heat in the current waste heat utilization mode, and also solves the problem of system design redundancy of the current waste heat recovery heat pump, the number of parts of the system is reduced on the whole, and the cost is reduced. And the weight and the cost are reduced.
