摘要
The present invention discloses a testing method and a testing system for a safe operating window of a lithium-ion battery in a squeezed state. The testing system includes a mechanical loading device, a heating device, a lithium-ion battery tester and a measuring device. By comparing the influence of a combined use of two or more of mechanical abuse with two different fixed variables, thermal abuse, and electrical abuse on critical conditions of thermal runaway of the lithium-ion battery, the influence of the different forms of abuse on the critical conditions of thermal runaway of the lithium-ion battery can be compared qualitatively and quantitatively, and these data can also be used to determine the safe operating windows of the lithium-ion battery under different abuse conditions.
