Patent ID: 8049470

Claim:
A method for charging a super capacitor bank without monitoring of a operating temperature of the super capacitor bank, the method comprising: providing a super capacitor charging circuit having a presettable charging voltage limit and a presettable charging current limit; setting the presettable charging voltage limit to a predetermined charging voltage level less than the maximum level associated with the worst case temperature within the super capacitor bank operating temperature range; setting the presettable charging current limit to a predetermined charging current level less than the maximum level associated with the worst case temperature within the super capacitor bank operating temperature range; providing a charging voltage and current to the super capacitor bank via the super capacitor charging circuit; limiting the charging current from the charging circuit to the predetermined charging current level during the charging; limiting the charging voltage from the charging circuit to the predetermined charging voltage level during the charging; sensing the charge voltage of the super capacitor bank; and turning off the charging voltage and current in response to a determination via the sensing step that the super capacitor bank has been charged to a desired charge voltage, whereby the super capacitor bank is charged at the limited charging voltage and limited charging current irrespective of operating temperature and without varying the charging with temperature.
