New energy vehicle power battery as the power source of the vehicle，The heat generated during charging and discharging will always exist.。The performance of power batteries is closely related to battery temperature。In order to extend the service life of the power battery as much as possible and obtain maximum power，Batteries need to be used within the specified temperature range。In principle-40°Cto+55°Cwithin range（actual battery temperature）The power battery unit is in an operational state。Therefore, current new energy power battery units are equipped with cooling devices.。

The popularity of new energy vehicles has madeElectric vehicle wadingSecurity has also become the focus of everyone's attention.Since electric vehicles rely on high-voltage output to drive the vehicle forward, water is conductive, especially rainwater, which contains more impurities and other components, which means stronger conductivity. Once the electric vehicle leaks electricity, the consequences will be disastrous.The waterproof performance requirements for new energy battery cooling mechanisms are also higher. Currently, new energy battery cooling mechanisms are required to meetIP68Waterproof rating.
Product to be tested: New energy vehicle battery cooling mechanism
According to the customer's needs, Hiraysi Technology uses the following equipment and solutions:
Equipment used:Hai RuisiHCClassic Series Air Tightness and Waterproof Testing Equipment
Solution: Use direct testing method to test pressure250KPA, inflation time5S, stabilization time15S, test time5S, upper limit of leakage value0.05KPA.Design the test fixture and tooling according to the structure of the battery cooling mechanism, place the battery cooling mechanism on the test fixture as required, press the start button at both ends to press down the upper mold to fix the product, and seal the air inlets. The instrument inflates, stabilizes and tests the inner cavity of the battery cooling mechanism from the four air inlets at both ends.The mold is equipped with a dotting device. When the test result isOK, the green dotting pen will mark the product.When the test result isNGIt is red.
