摘要： A method and system for charging a rechargeable battery, such as a Lithium based battery, by applying a voltage charge signal, and monitoring a battery charging current and a varying internal resistance of the rechargeable battery and changes in open circuit voltage of the rechargeable battery. The voltage charge signal is dynamically established as a function of the varying internal resistance of the rechargeable battery during charging and the changes in open circuit voltage of the rechargeable battery. The voltage charge signal is a function of a state of charge (SOC) of the rechargeable battery.

摘要： To prevent deterioration of a battery or reduce the degree of deterioration of a battery and to maximize charge and discharge performance of the battery and maintain charge and discharge performance of the battery for a long time. A reaction product formed on an electrode surface causes various malfunctions and deterioration of a battery typified by a lithium-ion secondary battery. The present inventors have found a breakthrough technological idea that a reaction product is prevented from being deposited on an electrode in charging or discharging or a formed reaction product is dissolved by application of an electrical stimulus to an electrochemical device that operates utilizing an electrochemical reaction, typified by a lithium-ion secondary battery. Specifically, the reaction product is dissolved by supplying a signal (inversion pulse current) with which a current flows in the reverse direction of a current with which a reaction product is formed.

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： Circuitry useable to protect and reliably charge a rechargeable battery, even from a zero-volt state, is disclosed, and is particularly useful when employed in an implantable medical device. The circuit includes two charging paths, a first path for trickle charging the battery at a relatively low current when the battery voltage is below a threshold, and a second path for charging the battery at relatively higher currents that the battery voltage is above a certain threshold. A passive diode is used in the first trickle-charging path which allows trickle charging even when the battery voltage is too low for reliable gating, while a gateable switch (preferably a PMOS transistor) is used in the second higher-current charging path when the voltage is higher and the switch can therefore be gated more reliably. A second diode between the two paths ensures no leakage to the substrate through the gateable switch during trickle charging. The load couples to the battery through the switch, and preferably through a second switch specifically used for decoupling the load.
