Patent Images
1. An apparatus for managing a battery unit having a plurality of storage batteries, comprising:
- a plurality of first voltage detecting means for detecting voltages of the storage batteries, respectively;
second voltage detecting means for detecting a total voltage of the battery unit;
defect detecting means for detecting defects in the storage batteries on the basis of the voltages detected by the first voltage detecting means;
abnormality detecting means for detecting an abnormal voltage in the battery unit on the basis of the voltage detected by the second voltage detecting means;
temperature detecting means for detecting temperature in the battery unit;
battery life determining means for determining a life of each of the storage batteries has dead, on the basis of the temperature detected by the temperature detecting means; and
information means for informing results of the detection performed by the defect detecting means and abnormality detecting means and results of the determination made by the battery life determining means.

Abstract
The voltages V of storage batteries Sa, Sb, . . . Sn are detected, and the voltage E of the battery unit 10 is detected. A defect in each storage battery is detected in accordance with the voltage V detected. An abnormal voltage of the battery unit 10 is detected in accordance with the voltage E detected. Further, the temperature T of the battery unit 10 is detected, on the basis of which the expiration of each storage battery is determined. The defect detected, the abnormal voltage detected, and the expiration determined are informed.
