Method for evaluating fire risk of lithium-ion battery

The invention relates to a method for evaluating the fire risk of a lithium-ion battery. The method for evaluating the fire risk of the lithium-ion battery provided in the embodiment of the inventioncan effectively calculate and evaluate the grade of the fire risk of the lithium-ion battery. The method for evaluating the fire risk of the lithium-ion battery can clearly obtain the safety state ofthe lithium-ion battery in the current state. When the fire risk of lithium-ion battery is high, the method can be chosen not to be used in engineering. The degree of the fire risk of the lithium ionbattery obtained by the method is conducive to solving the problem of safety judgment of the lithium ion battery, and is conducive to battery type selection and large-scale commercial application of the power supply industry. 本申请涉及种锂离子电池火灾危险性的评价方法。本申请实施例中提供的所述锂离子电池火灾危险性的评价方法，可以有效的计算并评价锂离子电池发生火灾危险性的等级。所述锂离子电池火灾危险性的评价方法，可以明确的得出当前状态下锂离子电池的安全状态。当锂离子电池火灾危险性较高时，可以选择不应用在工程中。本方法得出的所述锂离子电池发生火灾危险性的等级，有利于解决锂离子电池的安全性判断的问题，有利于电池选型及动力电源产
