Hello Lyes,

The SOC value cannot be forced. The bq34z100 must always be powered from the battery for best performance.

to restore the emitter it is necessary to charge absully to the max voltage. is there any other solution if we can't reach the max and min voltage?

RSOC can not be forced to a value, it can achieve accurate by charging it to Full or discharge to empty, the error is caused by the rush current when the system is repowered, if there could be no burst current for charge or discharge to the battery and the battery voltage is stabilized, then the SOC at power up can also be at a relatively better accuracy when you see the RDIS is clear and REST bit is set.
