Abstract

The invention discloses a fine spray type cooling battery energy storage system, and belongs to the technical field of energy storage batteries. The system comprises a battery management system, a DC-AC module, DC-DC modules, battery modules and a spray type cooling system; each battery module comprises a plurality of battery monomers and has waterproof leakproofness; each battery module is connected with one DC-DC module, all the DC-DC modules are connected with the battery management system, the battery management system is connected with the DC-AC module, and the DC-AC module is connected to an external power grid; a plurality of temperature sensors are arranged in each battery module and are connected with the battery management system; the spray-type cooling system comprises a water pipe and spray-type nozzles, the water pipe is connected to the water supply system, the spray-type nozzles are arranged around the battery module, and all the spray-type nozzles are communicated with the water pipe and can be independently opened and closed. The cooling performance of the energy storage system can be greatly improved, and the problem that the local temperature of the energy storage system is too high is solved.

Description

technical field [0001] The invention belongs to the technical field of energy storage batteries, and in particular relates to a fine spray cooling battery energy storage system. Background technique [0002] With the rapid development of the electrochemical energy storage system market, the safety of energy storage systems has gradually received attention. The energy storage system will release a large amount of heat during the charging and discharging process, and excessively high temperature will greatly affect the operation of the energy storage system and cause safety hazards. In addition, during the long-term operation of the energy storage system, the consistency of the battery will deteriorate, which will cause the temperature of the local battery to be much higher than that of the surrounding batteries, forming a high temperature point. If the high temperature point in the energy storage system is not timely Disposal may cause the battery to burn or even explode. T...
