  • Adaptive battery charging
    Patent number: 11095139
    Abstract: In an embodiment, adaptive charging of a battery is disclosed. In an embodiment, a device is disclosed comprising: a battery; at least one sensor configured to sense an outward pressure exerted by the battery; a monitoring module configured to monitor the outward pressure of the battery and at least one of a temperature, an age, a manufacturer, a state of charge, an impedance, and number of charging cycles of the battery; a control module configured to select a charging profile for the battery based on at least one of the sensed and/or monitored battery related variables; and a charging module configured to charge the battery according to a charging profile selected by the control module.

  • Impedance-based battery state estimation method
    Patent number: 9759782
    Abstract: The invention relates to a method, The method comprises measuring a first battery voltage of a battery of a device at and a first charging current after terminating a constant current charging mode and before initiating a constant voltage charging mode, producing a charging impulse on the battery, measuring a second battery voltage and a second charging current, and determining an impedance of the battery on the basis of a voltage difference between the first and the second battery voltage and a difference between the first and the second charging current. The invention further relates to an apparatus and a computer program product that perform the method.
