Abstract
The state of charging and discharging of a secondary cell circuit varies with battery deterioration and with the margin for charging and discharging. The state of charging and discharging is detected accurately without coming into contact with any unit cells, and maintenance and inspection can be performed efficiently. Charging and discharging characteristics of the battery are held in a memory, and charging current and discharging current are controlled by comparing measured voltage and current values with the charging and discharging characteristics held in the memory. Furthermore, battery information relating to each unit cell is transmitted by radio signals and the substance of this information is displayed at the driver's seat.
