Can Battery Packs Really Go Into the Water? Industry Standards and Practical Application Analysis

This paper analyzes the waterproof performance and industry standards of power batteries for new energy electric vehicles, pointing out that although the 2015 national standard requires batteries to undergo seawater immersion testing, the mandatory requirement has been removed in 2020. Nevertheless, battery companies still conduct watertightness tests to ensure safety. The article also discusses the waterproof ability of battery packs in practical applications, emphasizing that even if the battery passes multiple waterproof tests, the sealing may be reduced due to external factors such as cuts and scrapes, aging, corrosion, etc., thus affecting the performance of the battery.
