  • Patent number: 6771042
    Abstract: A method and apparatus for implementing a smart management of a rechargeable battery provides the basic capabilities to measure the operating parameters of a rechargeable battery including voltage, temperature and current flow, used subsequently to control the flow of charge/discharge current and for determining the operation mode of the rechargeable battery. The control circuit includes a central processing unit to manage the charge/discharge operation and control the current flow; a trickle charger for slow charging; a cutoff switch to turn off the temperature detector; and an economizer switch to reduce power loss during normal charging of the battery. If the operating voltage of the battery is below a predetermined limit, the system automatically switches to a self-cutoff mode. Through a combination of the above control means, battery management for rechargeable batteries can be improved notably.
