A tracked vehicle has a power control apparatus for controlling charging and discharging of a plurality of storage devices. A voltage measuring device measures voltages of the respective storage devices, and a current measuring device measures currents flowing through the respective storage devices. A status detecting device detects the operating status of each storage device based on values measured by the voltage and current measuring devices; and a charging/discharging controlling device controls currents, voltages, or power according to the operating status of each storage device detected by the status detecting device, to charge or discharge the storage devices.
