Abstract
Systems and methods are provided for charging a super capacitor bank. One method provides for determining a charge voltage for the super capacitor bank, providing a charging current, limiting the charging current according to a corresponding worst case temperature within the super capacitor bank operating temperature range, limiting the charge voltage according to the worst case temperature, and turning off the charging current once the super capacitor bank is charged. One system provides a super capacitor bank for storing energy providing specified power demand to a circuit, a current charger providing charging current to the super capacitor bank, the charging current limited in accordance with a corresponding worst case temperature within the super capacitor bank operating temperature range, a voltage sense circuit to detect the super capacitor bank voltage, and a control to disconnect the current charger from the super capacitor bank once the super capacitor bank is charged.
