According to the present invention, there is provided a secondary battery
control circuit which can perform a reliable charge/discharge control without activating
Positive Temperature Coefficient element. The secondary battery control circuit
includes a temperature detection section for detecting a temperature of the secondary
battery and a system logic for controlling charging/discharging of the secondary
battery based on the temperature detected by the temperature detection section.
The system logic interrupts the charging of the secondary battery in a case where
the temperature detected by the temperature detection section is out of a predetermined
first temperature range, and interrupts the discharging of the secondary battery
in a case where the temperature detected by the temperature detection section is
out of a predetermined second temperature range.
