Abstract

The present application provides an energy storage system, including a first shell, a battery pack, a sealing member, a first explosion-proof valve and a second explosion-proof valve. The battery pack is arranged inside the first shell and includes a second shell and a battery. The sealing member is arranged between the first shell and the second shell, and a space between the first shell and the second shell is fluidly isolated from an inner space of the sealing member. The first explosion-proof valve is mounted on the second shell to communicate with an inner space of the second shell and the inner space of the sealing member when the first explosion-proof valve is opened. The second explosion-proof valve is mounted on the first shell to communicate with the inner space of the sealing member and an outer space of the first shell when the second explosion-proof valve is opened.
