APPARATUS AND METHOD FOR CONTROLLING CHARGE CAPACITY BALANCING OPERATION OF SECONDARY BATTERY CELL
First Claim
1. A balancing control apparatus that controls charge capacity balancing of at least two secondary battery cells included in a battery pack, the balancing control apparatus comprising:
- a global positioning system (GPS) module to output current geographical location data of the battery pack using a signal received from a GPS satellite;
a real-time clock to store a present time; and
a control unit, for when the current geographical location data of the battery pack received from the GPS module matches any one geographical location information among at least one preset geographical location information and a battery management system (BMS) managing and controlling the battery pack is in a sleep mode, a real-time clock is used to calculate a sleep mode duration of the BMS, and when the calculated duration is more than or equal to a preset reference period, outputs a control signal for a charge capacity balancing operation of the secondary battery cells included in the battery pack.

Abstract
Provided is an apparatus and method for controlling a charge capacity balancing operation of a secondary battery cell. According to the present disclosure, the charge capacity balancing operation starts under the consideration of an environment condition suitable to perform the charge capacity balancing operation, so that sufficient time for the charge capacity balancing operation of the secondary battery cells may be ensured. Accordingly, this may reduce the possibility of the balancing operation being interrupted.

14. A balancing control method that controls charge capacity balancing of at least two secondary battery cells included in a battery pack, the balancing control method comprising:
-
(a) determining whether current geographical location data of the battery pack received from a global positioning system (GPS) module matches any one geographical location information among at least one preset geographical location information; (b) determining whether a battery management system (BMS) managing and controlling the battery pack is in a sleep mode when the geographical location data matches the geographical location information; (c) calculating a sleep mode duration of the BMS when the BMS is in the sleep mode, and determining whether the calculated sleep mode duration of the BMS is more than or equal to a preset reference period; and (d) outputting a control signal for a charge capacity balancing operation of the secondary battery cells when the sleep mode duration of the BMS is more than or equal to the preset reference period. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
