A power source has a battery pack housing a plurality of interconnected battery modules wherein a plurality of single cells are connected serially. A blower is provided which forces air through the battery pack to maintain the battery modules at a correct temperature. A controller controls the blower in accordance with data provided by sensors which detect voltage, current and temperature. The controller outputs the data and a state of charge. A charging/discharging current circuit includes a relay for interrupting charging and discharging of the battery modules in the event of failure and also includes a rush current prevention resistor and a current sensor. The controller permits the power source to be maintained in a correct operating condition wherein neither overcharging nor undercharging occurs.
