ABSTRACT:
A battery unit of a cartridge type for use as a power supply for electric motorcars, broadcasting apparatus and the like comprises a battery, a monitoring unit for monitoring the condition of the battery and storing information about the battery, a display for displaying data obtained by the monitoring unit, an I/O unit for sending out data representing the condition of the battery monitored by the monitoring unit to an external device, and a battery identification output unit for sending out a battery identification signal representing the type of the battery. The monitoring unit comprises a voltage measuring unit for measuring the supply voltage of the battery, a current measuring unit for measuring the current supplied from the battery, a temperature sensor for sensing the temperature of the battery, and a clock for indicating passage of time. The monitoring unit determines the quantity of residual electrical energy remaining in the battery when replacing the battery with a fully charged battery.
