<p>A method, a system, and a control unit for adjusting a charge voltage of a capacitor which is used as a power backup in a system having a required energy level. The method includes adjusting the charge voltage of the capacitor based on a received capacitance value and a received value of the required energy level. The energy level stored in the capacitor is kept essentially constant. The method and system are advantageous in that they extends the lifetime of the capacitor</p> |
