BQ34110 State-Of-Health (SOH)

BQ34110这个健康状态检测（State-Of-Health (SOH)）是通过哪些参数判断电池是否健康的？电池是否健康是怎么定义的？电池健康状态可以直接从IC内读取吗？

SOH is a percentage and is expected to change very infrequently. It represents the health of the battery compared to when it was new. It will only update when Qmax or learned resistance (Ra) changes. It does not depend on whether your battery is full or empty nor on the present temperature. It also doesn't depend on how the battery is currently being loaded. The gauge calculates SOH by running an FCC simulation at a fixed temperature (25degC) and a fixed load (customizable in dataflash through the "SOH Load I" parameter from Table 11).
