Electric vehicle batteries are the power source of electric vehicles，Most electric vehicles today are equipped with lead-acid batteries.，Lead-acid batteries are low cost，Great value for money.There are always so many rainy days throughout the year, so consumers who ride electric bikes will have a question？Will water enter the electric vehicle battery?？Are there any good measures to solve this problem?？

Product to be tested: Electric bicycle battery

Batteries are widely used as an energy source. The positive and negative electrodes of batteries are usually metal terminals with good conductivity. If used in rain or humid environment, the battery will short-circuit itself due to the conductivity of water, which not only consumes energy in vain, but also causes safety issues.Therefore, when the battery needs to be used in a rainy or humid environment, the battery must be waterproofed. The usual sealing body will cause difficulty in heat dissipation when the battery is working, and may even cause safety issues.Let’s take a look belowWaterproof test of electric vehicle batteriesWhat to do.

Electric bicycle battery waterproof test mold

According to customer requirements, electric bicycle batteries need to reachIP67For waterproof level, Hirays Technology uses the following equipment and solutions:

Equipment used:Hai RuisiHCClassic Series Air Tightness and Waterproof Testing Equipment

Solution: Use indirect testing method to test pressure15KPA, inflation time15S, stabilization time30S, test time30S, upper limit of leakage value0.05KPA.The test fixture is designed according to the shape of the battery to seal the entire battery, and the test tooling is customized according to the customer's requirements.Put the battery into the jig, press the start button and press down the upper mold and close the lower mold to seal the whole battery. The instrument inflates, stabilizes and tests the inner cavity of the jig. It detects the leakage value of the battery by monitoring the changes in the internal air pressure of the jig. Finally, the system automatically determines based on the set parameters.OKorNG。
