8. A method for charging a secondary battery, comprising:
-
a step of precharging the secondary battery;
a step of measuring a secondary battery voltage Vba1 after performing the precharging;
a step of terminating a charging for the secondary battery if the secondary battery voltage Vba1 is lower than a minimum prescribed voltage; and
a step of charging the secondary battery if the secondary battery voltage Vba1 is at least equal to the minimum prescribed voltage, wherein charging the secondary battery comprises one of a first charging in a first charge mode, a second charging in a second charge mode, and an active charging.
