摘要： A supply topology comprising an AC to DC or DC to DC adapter and an electronic device with an active system, a battery, and an adapter controller implements closed-loop control of adapter output voltage to limit power consumption by the electronic device to a value related to maximum adapter power. The adapter couples a signal representing maximum adapter power to a control line connected to the electronic device and the electronic device couples an error signal representing the difference between instantaneous power consumption and adapter maximum power onto the same control line. The adapter adjusts its output voltage in response to the magnitude of the error signal. An adapter controller in the electronic device sets a limit for allocating current to battery charging from the signal representing maximum adapter power, with battery charging current approaching zero as instantaneous power consumption approaches maximum adapter power. The adapter controller adjusts the limit for allocating current to battery charging in response to new values of adapter maximum power associated with alternate adapters connected to the electronic device.

摘要： A cell balancing system includes comparators coupled to battery cells. The Kth comparator of the comparators compares a cell voltage for the Kth battery cell of the battery cells with a reference threshold. A result of the comparison includes information useful for identifying a subset of the battery cells that have reached the reference threshold. The cell balancing system also includes a controlling logic circuit, coupled to the comparators, that selects a battery cell from the subset of the battery cells and turns on a corresponding switch to discharge the selected battery cell.

摘要： In a power converter, a primary winding receives an input power. In addition, multiple secondary windings transform the input power into multiple charging currents to charge a set of cells via a set of paths. The multiple secondary windings further balance the set of cells based on the charging currents. A ratio between a first turn number of a first secondary winding of the secondary windings and a second turn number of a second secondary winding of the secondary windings is determined by a nominal voltage ratio between two corresponding cells of the set of cells.

摘要： A battery monitoring system for a battery including multiple battery cells is disclosed. The battery monitoring system includes multiple first switch sets coupled across the battery cells respectively, an energy storage element, and a comparator coupled to the energy storage element via a second switch set. The energy storage element samples cell voltages of the battery cells via the first switch sets respectively. The comparator compares a respective cell voltage with a first reference signal to determine whether a fault condition occurs on a respective battery cell. The second switch set and one of the first switch sets are turned on alternately.
