Two types of typical risk modes and influencing factors of ESC of battery modules are analyzed and proposed. The effectiveness and limitations of weak links for protection in external short circuits of battery modules are verified.
In the case of a battery short-circuit, there may be such a drop of potential in the polymer that it will limit the short-circuit current. Thus, the polymer can be used as a promising short-circuit protection layer material for lithium-ion phosphate batteries, as it satisfies the theoretical requirements.
Two types of typical risk modes and influencing factors of ESC of battery modules are analyzed and proposed. The effectiveness and limitations of weak links for protection in external short circuits of battery modules are verified. A quantitative analysis method for the response time of the ESC protection device is proposed.
This study is the first to investigate the risk factors and protection design of battery modules with varying voltage levels in the context of external short circuit (ESC) faults. Three types of module ESC tests are carried out, including ESC without protection, ESC with weak links protection, and ESC with fuse protection.
Therefore, the arc extinguishing capacity of ESC protection device in the battery module should be matched with the module voltage level to ensure the safety of the breaking process. In conclusion, a fuse protection design is required for lithium-ion battery modules even if there is no fire or explosion during ESC of a single cell.
