化学ID匹配过程中报告显示,DOD error 大于 3%
如下图所示
充放电容量不准确会出现0%到100%突跳现象。
请问如何获取更准确的化学ID？
Star Xu：
您好，如果是用pack 做的充放电得到CHEM ID, 建议您用单个cell跑充放电试一下。

qingchen zhu：
你好 上面的测试数据是用单个电芯充放电得出的数据

Star Xu：
您好，一般计算CHEM ID 是用pack 跑数据计算ID, 如果计算的ID 误差过大，建议用单个cell 试一下。
您整个pack的是否做过充放电计算CHEM ID。
The bq78350 uses the chemistry of the cells to estimate the state of charge of the pack after a reset. Chemistry information is not loaded to the device as a Data Memory parameter but by using the Chemistry view. Loading the chemistry is not required for simple operation of the EVM but will be desired for setup of the board or a part for operation with cells, particularly if the chemistry differs from the default.
