Novel battery water cooling structure

Technical Field

The utility model relates to a novel battery water-cooling structure.

Background

At present, the stored electricity of a large energy storage system is often higher than tens of kilowatt hours or even several megawatt hours, the whole system is in the form of a large box/cabinet or a container, the total weight of the system is from hundreds of kilograms to several tons, and the system is often structured in a module type for installation feasibility and safety.

In a module type structure, in order to ensure that a battery system is always within a safe temperature range, a cooling system is particularly important, the cooling system which is commonly used at present is a combination of an air conditioner and a water cooling scheme, wherein in order to ensure the temperature uniformity of each group of battery modules, a water inlet and a water outlet are always required to be configured on each battery module.

Taking a megawatt energy storage container as an example, the number of battery modules exceeds 100 and even reaches more than 250, so that a megawatt energy storage container will contain 200 or even more than 500 water pipe interfaces. So many battery modules and water connections will cause the following two problems:

firstly, water leakage risk of a water pipe interface; secondly, the water inlet and the water outlet have higher temperature difference, so that the temperature of the system is controlled unevenly.
