  • 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.

  • Publication number: 20230314358
    Abstract: Methods, apparatuses and systems for radio frequency identification (RFID)-enabled information collection are disclosed, including an enclosure, a collector coupled to the enclosure, an interrogator, a processor, and one or more RFID field sensors, each having an individual identification, disposed within the enclosure. In operation, the interrogator transmits an incident signal to the collector, causing the collector to generate an electromagnetic field within the enclosure. The electromagnetic field is affected by one or more influences. RFID sensors respond to the electromagnetic field by transmitting reflected signals containing the individual identifications of the responding RFID sensors to the interrogator. The interrogator receives the reflected signals, measures one or more returned signal strength indications (“RSSI”) of the reflected signals and sends the RSSI measurements and identification of the responding RFID sensors to the processor to determine one or more facts about the influences.

  • Patent number: 11725626
    Abstract: The present invention relates to a method of controlling a wind turbine by automatic online selection of a controller that minimizes the wind turbine fatigue. The method therefore relies on an (offline constructed) database (BDD) of simulations of a list (LIST) of controllers, and on an online machine learning step for determining the optimal controller in terms of wind turbine (EOL) fatigue. Thus, the method allows automatic selection of controllers online, based on a fatigue criterion, and switching between the controllers according to the measured evolution of wind condition.
