Abstract

The invention discloses a new energy electric vehicle thermal management system with an all-weather multi-mode switching function. The new energy electric vehicle thermal management system comprises arefrigerating/heating system with the all-weather multi-mode switching function and a battery pack. The refrigerating/heating system comprises an air compressor, a four-way reversing valve, a gas-liquid separator, an expansion valve, a heat exchanger, a circulating pump, an electromagnetic valve set, a three-way valve set and a fin heat exchanger set. The battery pack comprises a battery box body, a voltage-sharing and shunting recombiner, a voltage equalizer and a junction station; the battery box body comprises a plurality of single batteries internally, and a heat accumulating type active/passive combined liquid temperature control unit is arranged between every two single batteries. The new energy electric vehicle thermal management system has multiple working modes, switching can beconveniently conducted under different weather conditions such as hot weather and cold weather, the multiple advantages of single-phase forced convection heat exchange, solid-liquid phase change heatexchange and gas-liquid phase change heat exchange are reasonably combined, and the requirements for compartment internal temperature adjustment and power battery temperature control and temperature equalization are met.

Description

Technical field [0001] The invention relates to a thermal management system for a new energy electric vehicle, in particular to a new energy electric vehicle thermal management system with a full climate multi-mode switching function, and belongs to the technical field of new energy electric vehicles. Background technique [0002] With the energy crisis and environmental pollution becoming more serious, pure fuel vehicles are no longer the most ideal means of transportation, and countries have successively planned to ban the sale of fuel vehicles. New energy electric vehicles are driven by electricity. Electric energy can be derived from renewable and clean energy such as solar energy and wind energy, reducing the consumption of traditional fossil fuels. Therefore, the development of new energy electric vehicles is one of the important measures for the automotive industry to save energy, reduce emissions and achieve sustainable development. One. The further development of new en...
