APPARATUS AND METHOD FOR CONTROLLING POWER FOR SECONDARY BATTERY
First Claim
1. A power control apparatus comprising:
- a sensing unit configured to measure a temperature of a battery cell, an outside air temperature around the battery cell and a load current;
an adjusting unit configured to adjust power supplied from the battery cell to a load; and
a control unit configured to estimate a future temperature change of the battery cell based on the temperature of the battery cell, the outside air temperature around the cell and the load current measured by the sensing unit, analyze the estimated future temperature change of the cell, and control the adjusting unit to reduce the power supplied from the battery cell to the load when the temperature of the battery cell is estimated to increase above a limit temperature for a preset reference time.

8. A power control method comprising:
-
measuring a temperature of a battery cell, an outside air temperature around the battery cell and a load current; estimating a future temperature change of the battery cell based on the measured temperature of the battery cell, outside air temperature around the cell and load current; determining whether the temperature of the battery cell increases above a limit temperature for a preset reference time, by analyzing the estimated future temperature change of the battery cell; and reducing output power of the battery cell when the temperature of the battery cell is determined to increase above the limit temperature for the reference time as a result of the determination. - View Dependent Claims (9, 10, 11, 12, 13, 14)
