Description

technical field

[0001] The present invention relates to a safety evaluation testing device for performing a predetermined safety evaluation test on modules or modules of an electrical storage device (hereinafter referred to as "electrical storage device group"). Here, a module refers to a member that combines a plurality of power storage devices of unit cells to form an integral body. In addition, a module refers to a component formed by combining a plurality of modules. Background technique

[0002] For example, a lithium (Li) ion battery as an electrical storage device has a higher energy density than other secondary batteries and can obtain a high output, so it has been widely developed.

[0003] However, the current status quo is that when an internal short circuit occurs in a Li-ion battery, due to rapid heat generation, the internal electrolyte (especially the solvent and electrolyte) decomposes and evaporates, producing harmful gases, or causing an explosion or eject...
