PROTECTION MANAGEMENT OF SUPER CAPACITATORS

A method for protecting a super capacitor includes monitoring a charge level of the capacitor, monitoring a temperature of the capacitor, discharging the capacitor when the temperature is above a predetermined level, or discharging the capacitor down to a predetermined level when the capacitor has s...

Beschreibung
Zusammenfassung:	A method for protecting a super capacitor includes monitoring a charge level of the capacitor, monitoring a temperature of the capacitor, discharging the capacitor when the temperature is above a predetermined level, or discharging the capacitor down to a predetermined level when the capacitor has stayed charged over said level longer than a predetermined period, and directing the discharged power from the capacitor to a cooling device for cooling the capacitor. Also, a super capacitor system includes at least one super capacitor, a control unit and sensor for monitoring the temperature and the charge level of the capacitor. The system further includes a cooling device connected to the super capacitor for cooling the capacitor.
