Abstract
Systems and methods are disclosed to store electrical energy in, for example, a vehicle. In an example system, a storage module is provided including one or more capacitors, a sensor to measure the temperature of the capacitor(s), and a control device that controls the voltage at the capacitor(s) so that the maximum voltage at the storage module and/or the individual capacitor(s) increases as the temperature decreases. The aging of the capacitor(s) and in particular electrochemical capacitors strongly depends on the temperature in addition to the operating voltage. Controlling the capacitor voltage based on temperature can, therefore, substantially reduce the aging of the capacitor(s).
