The invention discloses an integrated heat pump management system for a pure electric vehicle and the pure electric vehicle. The system comprises a compressor, a compartment exterior heat exchanger, acompartment inner heat exchanger, a battery cold plate, and a four-way valve which comprises four valve ports; the first valve port is communicated with an outlet of the compressor; the third valve port communicates with an inlet of the compressor; the compartment exterior heat exchanger, the compartment inner heat exchanger and the battery cold plate are arranged between the second valve port and the fourth valve port, the compartment inner heat exchanger and the battery cold plate are connected in parallel and then connected with the compartment exterior heat exchanger in series, and valvesfor controlling the opening and closing states of the corresponding connecting pipelines are arranged on the connecting pipelines for connecting all the elements. According to the system, switching of multiple heat management modes can be achieved according to the external environment and the working condition of the electric vehicle, the working condition coverage range is wide, the applicability is high, the heat management requirements of a passenger compartment and a battery pack of the whole vehicle under different working conditions can be met, the system efficiency is improved, and thepower consumption is reduced.
