    摘要: A circuit for charging a battery pack includes a power converter and a charger controller. The power converter is operable for receiving an input power, and for providing a charging power for charging the battery pack. The power converter provides galvanic isolation between input circuitry and output circuitry of the circuit. The input circuitry shares a first ground potential with the input power, and the output circuitry shares a second ground potential with the charging power. The charger controller in the input circuitry includes a modulator for generating a driving signal to drive the power converter and control the charging power.

    摘要: A circuit for charging a battery pack includes a transformer and a charger controller. The transformer is operable for receiving an input power and for providing a charging power according to a driving signal to charge the battery pack. The charger controller is operable for monitoring a status of the battery pack, for selecting a charging mode from multiple charging modes according to the status, and for generating the driving signal according to the charging mode to adjust the charging power. The charger controller further executes a state machine that stores data indicating predetermined battery statuses that cause saturation of the transformer, and that selects a protection mode in which said charging power is restricted if the status of the battery pack matches to one of the predetermined battery statuses.

    摘要: A battery management system includes a monitoring circuit and a charger. The monitoring circuit is operable for monitoring a battery pack that includes a plurality of cells, and for checking an unbalanced condition of the battery pack in each cycle of a plurality of cycles. The charger is operable for controlling a charging current to the battery pack and for receiving monitoring information from the monitoring circuit, and for adjusting the charging current from a first level in a previous cycle to a second level that is lower than the first level in response to a detection of the unbalanced condition in a current cycle.
