20090128094 | Alarm-including protection apparatus for lithium-ion battery and method thereof - An alarm-including protection apparatus and method thereof are used to protect a lithium-ion battery with a plurality of series cells. The protection apparatus includes a voltage balance controller for detecting the terminal voltage of each cell and correcting the terminal voltage of each cell. A protection unit and the lithium-ion battery are connected in series. A microprocessor connects to the voltage balance controller and the protection unit for receiving the terminal voltage of each cell and figuring out a voltage difference between the maximum terminal voltage and the minimum terminal voltage of the series cells. According to the comparison result of the voltage difference and a plurality of critical voltage differences, the microprocessor is used to correct the terminal voltage of each cell, generate an alarm signal or stop charging to the lithium-ion battery. | 05-21-2009 |
20090140696 | Apparatus and method for correcting residual capacity measurement of battery pack - A device and method of calibrating a residual capacity measurement for a battery pack uses the charging and discharging mechanism to reset the capacity to zero every time when the battery pack is completely discharged, so as to precisely measure and display the real capacity. The device includes a battery pack and a battery protection unit electrically connected to the battery pack. The battery protection unit resets the minimal capacity when the battery pack is completely discharged. The device further includes a charging switch used to control the timing of the charging unit to charge the battery pack; a discharging switch used to control the timing of the discharging unit to discharge the battery pack; a microcontroller used to detect whether the device is connected to the charging unit and capacity messages are generated; and a discharging switch used to control the battery pack to be completely discharged. | 06-04-2009 |
