  • Method for using a stand-alone system connected to a battery
    Patent number: 8816642
    Abstract: A method for using a stand-alone system, provided with an actuator connected to a battery, comprises during a discharging phase of the battery at a predetermined current the measurement of a temperature representative of the battery temperature and the determination of a first voltage threshold depending upon the measured temperature. Then, a voltage is measured at the battery terminals. An operating mode, selected at least between a normal and deteriorated mode, is determined, said stand-alone system being in the normal operating mode when the measured voltage is higher than the first voltage threshold, and in the deteriorated operating mode when the measured voltage is lower that the first voltage threshold, the current provided by the battery during an actuation being reduced when going from the normal mode to the deteriorated mode.
