コンデンサに加えられる所定の電力に反比例する。2. Description of the Related Art In recent years, electric double layer capacitors have been regarded as promising as a power source for electric vehicles. In order to fully use the electric capacity, it is essential to know the remaining capacity. The amount of electricity of the capacitor is theoretically calculated by the following formula. That is, the amount of electricity is W (watt hour),
Capacitance C (farad), when the terminal voltage is V (volt), is expressed by W = (1/2) × C × V 2/3600. Therefore, the remaining capacity of the capacitor can be known from the above formula based on the measured terminal voltage V of the capacitor. Further, from the above equation, it can be seen that the electric quantity W of the capacitor is proportional to the square of the terminal voltage V. Therefore,
When a predetermined voltage is applied to the capacitor, the terminal voltage V increases corresponding to the amount of electricity W charged in the capacitor. At this time, the time required for the capacitor to reach the desired terminal voltage V is inversely proportional to the predetermined power applied to the capacitor.

Therefore, according to the predicted travel route information, only when the overvoltage state of the capacitor-type power storage device does not continue, the power storage device can be charged in the overvoltage state, and as a result, the overcharge time that adversely affects the life of the power storage device is reduced. In addition, the traveling distance per charge for overcharging can be extended.
