Abstract

The invention relates to a container special for a lithium ion energy storage system and a using method of the container. According to the special container for the lithium ion energy storage system and the using method of the container, cooling and isolating devices are arranged between every two adjacent battery clusters and on one side of the last battery cluster respectively; an electrically operated valve is arranged above each cooling and isolating device; a spray head and a detector are sequentially arranged above each battery cluster; one end of each electrically operated valve is connected with the spray head through a water pipe; the other end of each electrically operated valve is connected with the cooling coil of the corresponding cooling and isolating device through a water pipe; the cooling coils are connected in series; the water inlet ends of the cooling coils are connected with a circulating pump; the water return ends of the cooling coils are connected with the circulating pump through a medium storage tank; and a controller is connected with the circulating pump, the electrically operated valves and the detectors. When the container is in a normal working state, a medium in the medium storage tank is subjected to closed-loop circulation by the circulating pump through the cooling and isolating devices, so that a cooling function is realized; when the detector reaches an alarm threshold value, an alarm is started, the electric valve is opened, the medium in the circulating pipeline is sprayed out from the spray head, and the effects of extinguishing fire, reducing temperature and cooling are achieved.

Description

technical field [0001] The invention relates to a special container for a lithium ion energy storage system and a use method thereof, which are used for storing lithium ion batteries of the energy storage system, and provide a good cooling environment and fire extinguishing safety guarantee for the lithium ion batteries. Background technique [0002] Lithium-ion battery energy storage is an important part of the future power grid and energy system, a necessary link in smart grid and energy Internet, and an important technical means to achieve the goal of carbon peak and carbon neutrality. Research and engineering practice at home and abroad generally agree that lithium-ion battery energy storage, as an effective means to realize the flexible adjustment of power grid supply and demand balance, is an important basic support for the realization of new technologies such as smart grid, energy Internet and micro-grid, and is the foundation of the future energy system. An important...
