The invention discloses a thermal management system of a pure electric vehicle and the vehicle. The thermal management system comprises a refrigerant side and a liquid preparation agent side, the refrigerant side comprises a compressor, an IHX internal heat exchanger, an LCC heat exchanger, an OHX external heat exchanger and a gas-liquid separator; the IHX internal heat exchanger, the LCC heat exchanger, the OHX external heat exchanger and the gas-liquid separator are connected through a first valve group, so that a refrigerant side respectively works in a heating/refrigerating mode; when the refrigerant side works in a heating mode, the compressor, the IHX internal heat exchanger, the LCC heat exchanger, the OHX external heat exchanger and the gas-liquid separator are sequentially connected and then return to the compressor to form a heating loop, and when the refrigerant side works in a refrigerating mode, the compressor, the IHX internal heat exchanger and the OHX external heat exchanger are sequentially connected and then return to the compressor to form a refrigerating loop; the liquid preparation agent side comprises a battery loop, an electric drive and electric control loop, a chiller loop and a heat dissipation loop; and the battery loop, the electrically-driven and electrically-controlled loop, the chiller loop and the heat dissipation loop are connected through the second valve group to form different series-parallel connection structures.
