The invention relates to a heat pump comprehensive waste heat utilization control method based on energy balance, which comprises the following steps of: constructing a refrigerant loop and a heating loop, and designing a pure water source heat pump balance mode, a pure air source heat pump balance mode and a double heat source heat pump balance mode by combining total heat demand, battery heat demand and calculation of available heat of a system; when the double-heat-source heat pump is in a heating state, air heat is absorbed through external exchange, and battery loop heat is absorbed through the battery cooling plate type heat exchanger; when the motor waste heat is in a heat pump state, the motor waste heat is used for heating the passenger compartment; when the air source heat pump is in a heating state, the passenger compartment and the battery are heated in the heat pump mode. According to the method, a unified centralized energy control strategy is adopted, energy requirements and balance of various mode working conditions are considered, and energy balance of all working conditions is achieved by planning a response waste heat utilization scheme in a heating requirement interval; the waste heat utilization function is high in full-scene self-adaptability, the waste heat utilization boundary is widened, the full-working-condition waste heat efficiency is high, and a self-adaptive algorithm is adopted.
