Application of High and Low Temperature Test System in New Energy Battery Test

The new energy test battery constant temperature cooling system is a high and low temperature test device used in the new energy vehicle industry. It can be applied to the performance test of new energy battery packs, motors, controllers, gearboxes, generators, inverters and other devices.

The temperature environment in the battery pack has a great influence on the reliability, life and performance of the battery cells. Therefore, it is especially important to keep the temperature inside the battery pack within the normal range. This is mainly achieved by cooling and heating of the temperature-controlled test system. The test object is connected to a test platform adapter. The part is cooled and heated by an aqueous glycol solution inside the test part. The test part needs to undergo a specific temperature change curve and the temperature change is recorded. The temperature variation usually ranges from -40°C to 100°C (expandable to 150°C). While controlling the temperature, you can also choose to control the flow or pressure.

The dynamic temperature control system can effectively test the environmental adaptability of the battery pack, improve the safety and reliability of the whole vehicle, and ensure the good operation of the vehicle in a variety of complex environments. The LNEYA new energy test cooling system currently adopts liquid cooling and direct cooling. Liquid cooling is heat exchange through liquid convection to take away the heat generated by the battery pack, thereby reducing the temperature of the battery pack and achieving the purpose of cooling. Direct cooling is to use refrigerant for cooling, and the refrigerant evaporates in the evaporator to quickly take away the heat of the battery pack to achieve the purpose of cooling the battery pack.

For these two cooling methods, liquid cooling is the preferred solution for many new energy vehicle battery packs. The liquid medium has high heat transfer coefficient and large heat capacity, so the cooling speed of the new energy test battery constant temperature cooling system is more. , for reducing the temperature of the battery pack and improving the performance effect of the battery pack at high and low temperature. The liquid-cooled system is more flexible in comparison, and the cooling channels of the battery modules can be set.

The configuration of the new energy battery test system of different manufacturers is different. When you choose, you should choose according to the characteristics of the equipment and your own working conditions.
