Abstract: A buck-boost converter includes a converter, for converting an input voltage into an output voltage, the converter including a plurality of switches and an inductor, and a controller for controlling the plurality of switches. The operation of the controller is driven by a finite state machine configured to receive as input state change signals and to provide as output state signals for driving the controller. The state change signals are generated by a comparator based on a comparison of a replica signal and an error signal, wherein the error signal is computed on the basis of a signal representative of a difference between a characteristic of the converter and a predetermined reference signal, and wherein the replica signal is representative of the current flowing through the inductor.

Abstract: Embodiments of the present disclosure includes an apparatus for estimating the state of charge of a battery, comprising: a first coulomb counter (STCC) for sampling a first charge variation (ΔQ) on the battery in a time comprising a number of predetermined periods, by adding up a battery current Im in each of the predetermined periods; a compensator for calculating a second charge variation (ΔQ_comp) by compensating for the first charge variation (ΔQ); a second coulomb counter (CCE) for calculating a first predicted charge amount (Qe) by adding up the second charge variation (ΔQ_comp); and a state of charge estimator for estimating the state of charge of the battery on the basis of the first predicted charge amount (Qe). The technique increases the accuracy of a state of charge estimation by compensating for characteristics according to battery temperature and aging.
