Abstract

The invention provides a method and a system for evaluating the health state of a lithium battery. The method comprises steps: open circuit voltage of the lithium battery is measured; according to theopen circuit voltage and in combination of upper and lower limit values of working voltage of different types of batteries and constant current charging / discharging time, the remaining capacity of the battery is calculated; and finally, according to the ratio of the remaining capacity of the battery to a nominal capacity, the health state of the battery is determined, and the larger the ratio is,the better the health state is. According to the method and the system for evaluating the health state of the lithium battery, the operation is simple and convenient, the speed is fast, scientific basis is provided for screening and grading combination of batteries in service, the service life of the lithium battery can be effectively prolonged, the whole life cycle cost of the lithium battery isreduced, and the effectiveness and the rationality of resource utilization are improved.

Description

technical field [0001] The present invention relates to the field of cascaded utilization of lithium batteries, and more particularly, to a method and system for evaluating the health status of lithium batteries. Background technique [0002] In the field of cascade utilization of decommissioned lithium batteries, the following two problems need to be solved: first, whether decommissioned lithium batteries can be used in cascade utilization; to evaluate. At present, a large number of lithium batteries in China are facing decommissioning. The huge pressure on environmental protection and asset disposal makes the cascade utilization of decommissioned lithium batteries an urgent technical problem that needs to be solved. From the perspective of application, the most important thing to solve is the adaptability of lithium battery status and application scenarios. By selecting suitable application scenarios for lithium batteries in different states, the stress in the cascade uti...
