In today's energy storage field, the reliability of container energy storage systems is crucial, and rain testing and waterproof testing are key links to ensure their performance. The following will delve into the key points of the relevant standard system.

1、 Experimental standard system

(one)Basic standard basis

1.GB/T 4208-2017The Protection Level of the Shell(IPcode)How to translate:This standard andIEC 60529:2013Equivalent, fully definedIPThe protection level is elaborated in detail fromIPX1to

IPX9KThe waterproof level testing method provides a basic framework for evaluating the waterproof performance of container energy storage systems.12.GB/T 5338.1-2023The Energy Storage Containerpart:General Technical Conditions

:For energy storage containers, this standard clearly specifies their adaptability and waterproof requirements in different environments, ensuring that the container can effectively resist rainwater invasion in various environments.3.GB/T 44026-2024Technical Specification for Prefabricated Cabin Lithium ion Battery Energy Storage System:Emphasize that the protection level of the battery compartment shall not be lower than

IP54.(two
