電気二重層キャパシタのための急速充電器の開発

Development of the quick charger for an electric double layer capacitor

Creators Okanouchi Satoru

We are trying to use electric double layer capacitor as the robots'power supply, to do the robot contest with the condition that electric quantity is almost constant. Developnent of a quick charger for electric double layer capacitor becomes a necessity to charge some capacitors in a short time before every game of robot contest. The quick charger that we developed this time charges a capacitor from a power supply device, monitoring the voltage of a capacitor to do not exceed the rating voltage usine the PIC microcontroller equipped with A/D transformation. Charging situation is displayed in LCD and charging is completed in about 20 seconds. Average of charging current is 10[A] and a contest robot can be driven about one　minute with one time charging.
