    摘要: A method and system for providing pulsed power and data from a main control unit (420) to slave units (415) via a first bus (430). The main control unit comprises an AC signal generator (414) for providing a plurality of first pulses (P1) on the bus for providing the power to the slave units (415). Each slave unit is AC-coupled to the bus via a first series capacitor (419) arranged for converting the first pulses (P1) into second pulses (P2). Data communication from the main control unit to the slave units is established by modulating the first pulses (P1), and by demodulating the second pulses (P2). The modulation may be based on Pulse Position Modulation. Zero, one or more bits may be communicated per first pulse. Optionally the slave units may communicate to the main control unit via a second bus (440).

    摘要: The present invention relates to a method and a corresponding device, for monitoring a charge of a battery. The method comprises obtaining (12) a battery current measurement value (I L ) and a battery voltage measurement value (V L ), and applying (14) a current integration method to update a primary charge estimate value representative of the charge stored in the battery by taking into account the battery current measurement value (I L ). The method further comprises determining (16) an ancillary charge estimate value representative of the charge stored in the battery using a battery model taking into account the battery voltage measurement value (V L ), and determining (18) an error value for said ancillary charge estimate value, in which the error value expresses the reliability of the battery model taking the battery voltage measurement value (V L ) into account. The method also comprises applying (20) a correction to the primary charge estimate value as function of the ancillary charge estimate value and the error value. Interpretation of the correction applied in this manner allows determination of current sensor offset and battery capacity change.
