Charging and discharging apparatus, method for controlling the same, and charging and discharging system including the same

A charging and discharging apparatus comprising:

• a charging and discharging channel part electrically connected to a plurality of battery cells;
• a plurality of jigs configured to support the plurality of battery cells;
• a temperature sensor part disposed at one side of the plurality of jigs to measure a temperature of an area adjacent to the plurality of battery cells;
• a controller configured to control the temperature sensor part, charge or discharge the plurality of battery cells through the charging and discharging channel part, and calculate a charging capacity of each battery cell;
• and
• a server configured to communicate with the controller,
• wherein the controller is configured to calculate a modified charging capacity of each battery cell using a preset equation on the basis of the temperature measured through the temperature sensor part and the calculated charging capacity of each battery cell when the plurality of battery cells are charged through the charging and discharging channel part so as to transmit the calculated modified charging capacity to the server.

A method for controlling a charging and discharging apparatus, the method comprising:

• a process of charging or discharging each of battery cells through a charging and discharging channel part electrically connected to the plurality of battery cells;
• a process of calculating a charging capacity of each battery cell during the charging of each battery cell through the charging and discharging channel part on the basis of the temperature measured by the temperature sensor part, which is disposed at one side of a plurality of jigs that support the plurality of battery cells to measure a temperature of an area adjacent to the plurality of battery cells;
• and
• a process of modifying the charging capacity of each battery cell using a preset equation on the basis of the temperature and the calculated charging capacity of each battery cell.
