  • Publication number: 20130043841
    Abstract: The present invention provides a circuit and a method of measuring battery voltage. During the charging, the method adopts cycles of charging, stopping charging, discharging, stopping discharging, and measuring voltages. Within each cycle, between the discharging and the measuring voltage, multiple times of pulse discharging are conducted. After each pulse discharging, the battery voltage is immediately measured until the voltage returns to a stable voltage. Then, the next pulse discharging is conducted. By comparing the stable voltages obtained from successive pulse discharging, whether the virtual voltage is removed and whether the real voltage has been obtained is confirmed. Then the real voltage is further used to determine if the battery is fully charged.

  • Patent number: 8084995
    Abstract: An intelligent lithium-battery-activating charging device is connectable between a charging power source and an application electrical device and contains an internal circuit that builds up a charging/discharging mode to correspond the charging power source to a lithium battery accommodated in the application electrical device. After a short time period of charging, which is short enough that the voltage detection circuit inside the application electrical device cannot properly respond, a time period of discharging follows and then discharging is stopped, so that the detection performed by the voltage detection circuit is delayed until the cycles of short time period charging and discharging are completed. If the detection shows the battery is not fully charged, then the charging operation starts again. During the charging process, ions are moved in one direction in one moment and then reversed in the next moment so that built up of deposition on electrodes can be avoided.
