Abstract

An energy storage container and a heat dissipation system for the same are provided. The heat dissipation system for the energy storage container includes a container body, and a battery module assembly and multiple air conditioning modules both located in the container body. In a length direction or a width direction of the container body, each of two side ends of the battery module assembly is provided with at least one air conditioning module. The heat dissipation system further includes an air supply duct and an air return duct, a partition plate is arranged in the air supply duct, to divide the air supply duct into a first air supply duct and a second air supply duct which are mutually independent. The above arrangement avoids increasing a height of the energy storage container, thereby effectively facilitating the transportation and installation of the energy storage container.

First claim
