Publication number: 20080191665Abstract: A charging circuit is provided. In the present invention, a capacitor and a resistor are added to the circuit near the charging switch. Due to the electrical charges stored in the capacitor, the rising and decreasing rate of the battery voltage of a rechargeable battery can be diminished during the pulse charge stage. Thereby, the probability of battery cell damage is reduced, and the safety of using the rechargeable battery is guaranteed.Type: ApplicationFiled: June 28, 2007Publication date: August 14, 2008Applicant: COMPAL ELECTRONICS, INC.Inventors: Kung Shao-Tsu, Chuang Chih Tarng, Chen Chia Chang

Publication number: 20080169786Abstract: A method for charging a battery module including a plurality of parallel-connected battery core sets is provided. In the present method, a constant charging current is provided for charging the battery module first. Then, the voltage of each parallel-connected battery core set in the battery module is determined whether reaches a nominal voltage. If it reaches the nominal voltage, the charging current or charging voltage applied to the battery module is adjusted for charging the parallel-connected battery core set having the maximum voltage with a constant voltage. Finally, it is determined whether the electric power of the battery module is fulfilled. If not yet fulfilled, a constant voltage is continuously supplied to the battery module for charging until the electric power of the battery module is full. Accordingly, the present invention can charge the battery more quickly with taking the safety of the battery into account.Type: ApplicationFiled: July 31, 2007Publication date: July 17, 2008Applicant: COMPAL ELECTRONICS, INC.Inventors: Chen Chia Chang, Chuang Chih Tarng
