ABSTRACT:
Disclosed are a battery package and a method for charging and discharging secondary batteries including nickel hydrogen batteries by refreshing and suppressing inactivity of the batteries. More concretely, battery package (101) comprises a group of batteries having a plurality of connected secondary batteries, each forming a unit battery, a plurality of sensors for detecting a temperature and a voltage, a display device for displaying a condition of the group of batteries, a switch for controlling charge and discharge of the group of batteries, and an operational control circuit (4) for generating a signal based on signals input from the plurality of sensors to make the display device display the condition of the group of batteries and to activate the switch, wherein the battery package (101) is provided with refreshing demand display device (13) for displaying a need to initiate a refreshing charge and discharge, and it uses the method of carrying out the refreshing charge and discharge automatically when a recovery voltage of the secondary batteries does not exceed a predetermined voltage after a lapse of a predetermined time from a moment when the secondary batteries come to a final discharge voltage. This invention can thus carry out the refreshing charge and discharge even for secondary batteries that become inactive after having been left unused for a long time.
