EV Battery Motor Test Chiller -25℃~+100℃

EV Battery Motor Test Chiller -25℃~+100℃

The System Process Flow Is As Follows:

The liquid refrigerant in the evaporator of the unit is exchanged with the circulating air in the interior of the tank. The temperature rises from liquid to gas, and is sucked into the suction port of the compressor. The high-temperature and high-pressure refrigerant gas after compression by the compressor passes through The oil separator separates the refrigerating machine oil carried in the compression process, and then enters the condenser, and exchanges heat with ambient air or cooling water to change from high temperature and high pressure gas to high pressure normal temperature liquid. The high-pressure normal temperature refrigerant liquid is dried by a filter and then throttled and depressurized by an expansion valve, that is, from a high-pressure liquid to a low-pressure liquid. The low-pressure liquid (lower boiling point) enters the evaporator of the unit, and the cooling air is brought to the inside of the tank through the circulating air to achieve refrigeration.

The anti-freeze solution is injected into the 80L pressure vessel, and the fully closed circulation system is adopted. This avoids the opportunity for the antifreeze to contact with the outside air and ensures the condensation of the water. After the expansion tank is protected by nitrogen, the temperature range of the heat transfer liquid is also broadened because its boiling point is increased. In addition, oxidation of the thermally conductive liquid in contact with oxygen in the environment is also avoided, thereby extending the useful life of the thermally conductive liquid.


  • EV Battery Motor Test Chiller are widely used in extreme performance testing of motors and battery packs, rapid rise and fall thermal shock tests, and comprehensive environmental adaptability evaluation tests.
  • The product is suitable for a new generation of energy-type battery packs, which can effectively test the super environmental adaptability of the battery pack, improve the safety and reliability of the vehicle, and ensure the good operation of the vehicle in a variety of complex environments.
  • The test object is connected to a test platform adapter; the inside of the component is cooled and heated by the glycol aqueous solution; the test component needs to go through a specific temperature change curve and record the temperature change.
