ABSTRACT:
A protection circuit controls charging/discharging of a battery pack in both a high temperature region and a low temperature region. The battery pack is protected from the risk of firing, burning or explosion which occurs in a high temperature region, to secure its safety. Furthermore, the charging and discharging of the battery pack is controlled in a low temperature region, to prevent incomplete charging and to increase the battery capacity efficiency.
