Description

Technical Field

[0001] The present invention relates to the technical field of energy storage battery performance testing, and in particular to a container energy storage battery performance comprehensive testing device. Background Art

[0002] MW-class containerized battery energy storage system (CBESS) is an important support for the future development of power grids, and can effectively improve the stability, reliability and power quality of power systems. MW-class containerized battery energy storage system uses lithium iron phosphate batteries as energy carriers, charges and discharges through PCS, realizes various energy exchanges with the power system, and can be connected to various power supply modes, such as photovoltaic arrays, wind power, diesel generators and power grids. The output of the energy storage system can be connected to the grid, supply various load equipment and electric vehicle chargers. In recent years, battery energy storage technology has developed rapidly at home and abroad. Containerized battery energy storage systems have the advantages of high capacity, high reliability, high flexibility, and strong environmental adaptability, and have broad application prospects in power grid systems.

[0003] Since lithium is a metal that is particularly prone to chemical reactions, it is easy to expand and burn.

The energy storage battery 34 that passes the second heating test is qualified. The high-temperature testing device 4 can first perform a high-temperature operation test on the energy storage battery 34 under normal conditions, and the impact testing device 5 can perform impact tests on the six end faces of the energy storage battery 34 in turn. After the comprehensive impact test, a second high-temperature operation test is performed, thereby ensuring that the energy storage battery 34 will not catch fire or explode at high temperature after multiple impacts, thereby improving the accuracy and comprehensiveness of the energy storage battery 34 test.

[0056] S4: When a defective energy storage battery 34 catches fire or explodes during the test, the explosion-proof glass 7 can be used to observe the internal situation of the explosion-proof box 51, the vacuum pump 8 can quickly extract smoke and air to achieve the effect of auxiliary fire extinguishing, and the pressure relief port 9 can release the explosion pressure inside the explosion-proof box 51, avoiding the occurrence of explosion accidents, which is conducive to the subsequent treatment of the discarded energy storage batteries 34 after the fire and explosion.
