BATTERY, BATTERY ADJUSTMENT DEVICE, AND METHOD AND PROGRAM FOR ADJUSTING BATTERY

摘要

PROBLEM TO BE SOLVED: To bring out the performance of a battery pack better when replacing a secondary battery composing the battery pack.

SOLUTION: A battery module for replacement 30 comprises: battery rows 310 composed of serially connected cells; a switch 320 connected to the battery rows 310 that closes to build a circuit in which a plurality of battery rows 310 are connected in parallel; a variable resistor 330 serially connected with the circuit in which the plurality of battery rows 310 are connected in parallel; and CMU 340 that adjusts the inner resistance of the battery module for replacement 30 by adjusting the capacity of the battery module for replacement 30 through open/close control of the switch 320 and by adjusting the resistance value of the variable resistor 330. As the CMU340 adjusts the capacity and the inner resistance of the battery module for replacement 30 to match them with the capacity and the inner resistance of the remaining battery module equipped in the battery pack 10, the characteristics of the battery pack 10 can be brought out better when charging and discharging the battery pack 10 with the battery module for replacement 30 mounted.
