Abstract:
1. A battery testing device that charges a chargeable secondary battery by using a charging module, comprising: an input control module that controls an input power that the charging module inputs to the secondary battery; an output control module that controls an output power that is output from the secondary battery and discharges the secondary battery; a temperature adjustment device configured to heat and cool the secondary battery, the temperature adjustment device configured to increase the temperature of the secondary battery from a first temperature of about 50° C. to a second temperature of about 150° C. for a period of about 3 hours when a battery capacity of the secondary battery falls below a threshold, wherein the temperature adjustment device judges whether the temperature of the secondary battery rises to 160° C. or more while performing adjustment to hold the temperature of the secondary battery at the second temperature, and displays a result of the judgment on an external device, wherein the input control module and the output control module are configured to cyclically perform a plurality of charge/discharge cycles, and each charge/discharge cycle includes:
