\n\tThe normal working temperature
\nrange of power batteries for electric vehicles is -30 ~ 52 \u00b0 C, and the working
\ntemperature range is -46 ~ 66 \u00b0 C, which is difficult to achieve with existing
\npower batteries. Although local warming measures can be used for battery packs,
\nthey increase costs. Each type of battery has an optimum operating temperature
\nrange, beyond which battery performance will be reduced or impaired. Therefore,
\nbefore the production of power batteries, manufacturers need to perform related
\ntemperature tests or inspection agencies to perform similar tests.<\/span><\/p>\n

\n\tThe cooling and heating
\nsystem components of electric vehicles must be tested at different pressure
\nlevels and temperatures. The performance and power consumption of these systems
\nmust be tested to ensure that they do not significantly reduce the mileage of
\nthe vehicle. In a typical test, a complete auxiliary heater or component, such
\nas a valve, hose, and other hollow valve, is inserted into a test slot on a
\npressure cycle table.<\/span><\/p>\n

\n\tA cooling circuit is
\nusually tested in a temperature range of minus 40 to 20 degrees, while a
\nheating circuit is tested in a temperature range of 20 to 140 degrees. Power
\nconsumption and performance are usually tested at alternating temperatures.
\nLow-voltage or high-voltage power sources can be selected, and operation can be
\nsimulated with on-board batteries and generators or traction accumulators. In
\nmany electric vehicles today, heating and cooling systems can drain the
\nbattery, negatively affecting the mileage of the car. By comparing the test
\nresults before and after the load test on the pressure cycle test bench, we can
\nsee how the change in battery power consumption and performance affects the
\nservice life of the vehicle.<\/span><\/p>\n

\n\tA comprehensive
\nlong-term test usually takes 20 to 30 days, depending on how often the load
\nchanges. The temperature and volume flow of the test medium and the ambient
\ntemperature (if the test takes place in a climatic chamber) vary according to
\nthe test specifications. The temperature and flow rate, pressure, and pressure
\ndrop of the inlet and outlet of the test object circuit are continuously
\nmeasured. The test here focuses on the thermal and electrical performance of
\nthe heating and cooling device under different environmental conditions.<\/span>\n<\/p>\n

\n\t Lneya’s new energy battery cooling
\nand heating system KRY series is widely used in production lines or testing
\ndepartments of related companies in China. The temperature control precision is
\nhigh, and the single fluid medium temperature control saves resources and
\ncosts.<\/span><\/p>\n
