The invention discloses an energy storage device. The energy storage device comprises a container, a plurality of battery modules and at least one waste discharge explosion-proof assembly, a bracket for placing a battery module is arranged in the container; the battery module comprises a battery box and a plurality of single batteries; wherein the battery box is provided with an accommodating space for accommodating a plurality of single batteries and a waste discharge space isolated from the accommodating space; one end of each single battery is provided with an explosion-proof valve communicated with the waste discharge space, the waste discharge explosion-proof assembly comprises a waste discharge pipe and a waste discharge box communicated with the waste discharge pipe, and the waste discharge pipe is installed on the support and communicated with the waste discharge space of each battery box. The beneficial effects of the invention are that: an explosion-proof joint is arranged ona single battery, and the waste discharge space communicated with the explosion-proof joint is arranged on a battery box; and meanwhile, the waste discharge explosion-proof assembly communicating with the waste discharge space is arranged to collect waste gas and waste liquid, and fire disasters caused by the waste gas and the waste liquid can be effectively eradicated.
Description
[Technical field] [0001] The present invention relates to the field of battery technology, and more particularly to an energy storage device. 【Background technique】 [0002] Lithium-ion batteries have been widely used in various fields such as medical, communication, transportation, and storage due to large capacity, cycle performance and green environmental protection. In particular, the storage capacity has been greatly developed in recent years, especially container type. The energy storage device is widely used due to the convenience of mobile. In the prior art, when an abnormal monomer battery occurs in a container storage device, it can only be reduced by power failure. At this time, the energy storage device not only cannot be used, but an abnormal monomer battery is likely to leak some high-pressure high temperatures. The gaseous or liquid electrolyte, which is easy to cause the energy storage device to appear. [0003] In view of this, it is necessary to provide an energ...
