  • Method for pulse charging in voltage control mode with steps of variable amplitude
    Patent number: 11784505
    Abstract: The present invention relates to a method for charging an electrochemical cell of a rechargeable battery with charging pulse control (PL), the pulses (PL) being driven in voltage control mode in the form of voltage steps (Pt) of variable amplitude. According to the invention, the method consists in calculating the value (Ut+1) of each voltage step (Pt+1) with respect to the value (Ut) of the preceding voltage step (Pt) and according to a progression variable representative of the variation in the internal resistance of the cell (d(R)/dt), for a period ending on the preceding step (Pt), with respect to a predetermined tolerated variation threshold (?), where Var=d(R)/dt??. The method applies to high-voltage electric battery charging protocols for electromobility or stationary applications, or portable device batteries, for example.
