The waterproof rating of lithium batteries is mainly based on the IP (Ingress Protection) rating system, of which IP67 and IP65 are two common waterproof and dustproof rating standards.IP67 means that the device can be immersed in water for a short period of time under certain conditions, which usually refers to a 1-meter-deep immersion in water for 30 minutes without any effect, while IP65 means that the device is able to resist low-pressure water flow from any IP65 means that the device is resistant to low-pressure water coming from any direction, making it suitable for outdoor use or environments where there is a risk of water splashing. Both ratings are rated "6" for complete protection against dust, which means that it is protected against foreign objects and dust, and is the highest level of protection against dust. IP67 "7" means that the device can be immersed in water, while IP65 "5" means that it can resist low-pressure water flow.
Waterproof and Dustproof Test
The waterproof and dustproof test consists of two parts: the dustproof test and the waterproof test. The dustproof test evaluates the dustproof performance of the battery through a dust chamber test and a static cling test. The waterproof test includes a water spray test, which simulates rain or splashing water, and an immersion test, which verifies the waterproof sealing of the battery. In addition, there are air tightness tests and environmental reliability tests to ensure the stability of the battery in harsh environments.
Specifically for lithium batteries for battery cars, some advanced technologies and manufacturers have developed IP68-rated fully waterproof lithium batteries, which can maintain high performance regardless of typhoons, torrential rains or shallow depressions, showing high safety, long life and strong power. This shows that with the advancement of technology, the waterproof grade of lithium battery for battery car continues to improve to meet a wider range of usage requirements and environmental challenges.
