20080284380 | BATTERY CHARGING APPARATUS - A battery charging apparatus connects secondary batteries of the battery pack, plurality of charge terminals and two discharge terminals to form plurality charge paths and a discharge path, which has a main switch provided on the discharge path, a main controller connecting the battery pack and the main switch, plurality of sub switches provided on the charge paths, plurality of sub controllers connecting secondary batteries of the battery pack and corresponding sub switches, a thermal controller connecting the main controller and a temperature switch. The temperature switch connects the sub switches. The main controller and sub controllers monitor charge state and discharge state of the battery pack to set the main switch and sub switches cut off the discharge path and the charge paths. The thermal controller monitors temperature of the battery pack and main switch to set the main switch and the sub switches cut off the discharge path and the charge paths. | 11-20-2008 |
20100244772 | Battery module - A battery module adapted for supplying power to an electric equipment includes an energy battery device, a power battery device and a charging device. The energy battery device includes a plurality of parallel conductive plates and energy battery groups each connected between the neighboring two conductive plates and including a plurality of parallel-connected energy cells. The power battery device is adapted to be connected with the supplied electric equipment and includes a power battery group formed by a series-connection of a plurality of power cells. The charging device has two input terminals connecting the energy battery device therebetween and two output terminals connecting the power battery device therebetween so that the power battery group can be charged by the energy battery device, the two output terminals connected with the electric equipment for supplying power to the electric equipment by the energy cells. | 09-30-2010 |
20100246084 | Control circuit - A control circuit includes a voltage-dividing resistor connected to a voltage input terminal, at least one thermal breaker series-connected between the voltage-dividing resistor and the ground and disposed near one corresponding battery, and an output terminal drawn forth from a connection location of the thermal breaker and the voltage-dividing resistor and adapted to be connected with a protective circuit. The thermal breaker breaks according to the temperature of the corresponding battery, and then the output terminal transmits different protective signals to the protective circuit according to the working state of the thermal breaker so as to make the protective circuit protect the battery based on the protective signals. Therefore, the control circuit of the present invention is relatively simpler and occupies a relatively smaller space so that can meet the demand of both miniaturization and low cost of electronic products. | 09-30-2010 |
