We are using the bq27200 fuel gauge in a battery operated product. One feature is that the circuit uses the battery capacity information to calculate when to force the sleep mode.
My problem is that in production, a relatively charged battery is being inserted in the product. On power up, the reported battery capacity is 0%. The circuit goes into sleep mode, meaning that the discharge current is very small. When a charger is connected, the battery does not charge much, because it is already full. Therfore, discharge/charge cycling is very difficult, and the reported available capacity dosn't reach the correct value.
All battery parameters are currently programmed in the EEPROM, and we have access to the ram registers, Is there a way to initialize the available battery capacity to have upon powerup, an initial value close to 100% instead of 0%?
