<p>The charged and discharging states of a secondary battery circuit which fluctuate in accordance with the charging and discharging margins or deterioration of the battery are accurately detected without touching each unit cell so that the maintenance and inspection of the battery can be performed efficiently. The charging and discharging characteristics of the battery are stored in a memory and the charging current and discharge current of the battery are controlled by comparing measured voltage and current values of the battery with the charging and discharging characteristics stored in the memory. In addition, the battery information of each unit cell is transmitted by using radio signals and the content of the information is displayed at the driver's seat.</p> |
