Publication number: 20080169784Abstract: A solar power system uses a solar panel to convert light energy to electricity for charging a battery through a photo sensor. The photo sensor uses a switching unit to control whether the battery can be charged or discharged. The battery further connects to a sensing and protecting circuit and an over-discharge protecting circuit. The sensing and protecting circuit protects the battery from being over-charged. The over-discharge protecting circuit stops the discharging of the battery when the output voltage of the battery is lower than a low threshold.Type: ApplicationFiled: May 10, 2007Publication date: July 17, 2008Applicant: Chen-Yuen FANInventors: Kan-Shiong Chung, Chen-Yueh Fan

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

Publication number: 20080169788Abstract: A battery pack features a shock-absorbing and sealed construction and an electronic control module that provides automatic recovery circuitry in the event of a short circuit in the load whereby the power is terminated and then restarted at a lower level so that removal of the short circuit may be detected. Full power is restored to the load when the short circuit is removed. In addition, the electronic control module of the battery pack uses the battery pack load, such as a cap lamp, to provide an indication of a low battery charge level. The electronic control module also provides a soft-start feature where the power provided to the bulb is ramped up to avoid current in-rush to the bulb during startup.Type: ApplicationFiled: January 14, 2008Publication date: July 17, 2008Inventors: Joseph Bobbin, Mark Dirsa
