CAPACITOR (i-ELOOP) [i-ELOOP]

id131704502000

Purpose, Function

• The capacitor (i-ELOOP) is a storage battery which can be charged with/discharge large amounts of current instantaneously. In conjunction with the variable voltage type generator which can generate a maximum of 24.3 V, the capacitor (i-ELOOP) can also be charged efficiently with the generated power in a short period of time.

Construction

• The capacitor (i-ELOOP) is installed directly below the front combination light (LH).

• The capacitor (i-ELOOP) is equipped with service plug. A short circuit can be prevented by pulling out the service plug because 24.3 V related power is interrupted.

• A thermistor type temperature sensor is equipped inside the capacitor (i-ELOOP). The temperature sensor detects the temperature of the capacitor (i-ELOOP) and inputs the signal to the DC-DC converter (i-ELOOP).

• A discharge box is equipped in the capacitor (i-ELOOP). The discharge box serves the purpose of assuring safety when the capacitor (i-ELOOP) is discarded. By forcing the capacitor (i-ELOOP) to discharge using the resistor, the capacitor (i-ELOOP) will not ignite even when pressed.

• Although the battery generates chemical reactions to charge/discharge electricity, the capacitor (i-ELOOP) does not, and instead charges/discharges physically. As a result, the capacitor (i-ELOOP) is able to charge/discharge large amounts of electricity more rapidly than the battery, and deterioration of the electrodes is gradual with a long service life.

Charging

― Electrical charge adheres to surface of electrodes.
