ABSTRACT:
A system and process of properly controlling the charging and discharging a smart battery of an electronic equipment even if data information of the smart battery is not exact. The process is comprised of receiving data information from the smart battery and then detecting a charged level of the smart battery; checking, through analog/digital converting terminals a power terminal of the smart battery and directly detecting a battery voltage of the smart battery; determining whether the charged level is at a low-charged level; determining whether the battery voltage is lower than a first predetermined voltage; outputting the low battery state to the system if the charged level is at the low-charged level and the battery voltage is lower than the first predetermined voltage; determining whether the charged level is at a shut-down level; and determining whether the battery voltage is lower than a second predetermined voltage, and turning off the system, if the battery voltage is lower than the second predetermined voltage.
