锂离子电池荷电性能检测及健康状况分析
The lithium battery based on the voltage change rate will detect SOH
In order to get a convenient and fast method for lithium battery health status detection, 18650 type lithium-ion battery was chosen as the experimental object, aging test was performed, and the change of charge performance during aging process was recorded. After removing the effect of self heating of the battery discharge, the lithium battery comparison of different aging degree under the charge performance, found that with the change of the health status of the lithium battery, the voltage change rate will also change, so as to obtain a new method by detecting the charged performance testing on the health status of lithium battery. The experimental results show that the method is fast and accurate, and can be used as an effective method to detect the health state of lithium batteries, and is suitable for the detection of lithium batteries in batch.
