| 20120112688 | Battery Module with Less Charging Time and Charging Method of the Same - The battery module comprises a main battery, a voltage converter, an auxiliary device, a battery management unit and a first set of switching devices and a second set of switching devices. The main battery provides the electric power. The auxiliary device is used to store the electric power. The battery management unit controls the main battery and the auxiliary device to charge or discharge through a first set of switching devices and a second set of switching devices, respectively. When the battery module is charged by an external charger, the auxiliary device and the main battery are charged simultaneously. When the external charger stops to charge the battery module, the battery management unit controls the auxiliary device through the second set of switching devices to continuously charge the main battery through the voltage converter. | 05-10-2012 |
| 20110193527 | Lithium Battery Module - A lithium battery module with multiple-cells connected in parallel is disclosed. The lithium battery module comprises a battery management unit, a power converter (optional) and each cell with an individual charging control switch and a discharging control switch in series connected with the cell and is independent controlled by the battery management unit so that a charger is capable of charging the designate cell or more or disable one among them. | 08-11-2011 |
| 20110037475 | Battery Capacity Estimation by DCIR - A method of battery capacity measurement is actualized by battery internal resistance. This method establishes a controlled discharge path inside the battery module. The battery discharge current is a constant value despite of the variation of system loading current. The internal resistance measured by establishing this constant battery current can be used to obtain the battery capacity precisely. | 02-17-2011 |
| 20100217552 | Battery Management System for Measuring Remaining Charges in a Battery Packet with Multi-Cells - A battery management system for measuring remaining charges in a battery packet with multi-cells is disclosed. The battery comprises electric property and non-electric property measuring modules, multi-cells, a slave communication protocol controller, and a battery protective circuit. The portable device comprises an embedded controller and a charge gauge module and a master communication protocol controller. The parameters demanded for calculating the remaining charges of the multi-cells are measured by the electric property and non-electric property measurement modules and transferred through the SMBus interface to the embedded controller and the charge gauge module. Therefore, the battery management system can manage the remaining charges of every cell in the multi-cells without a microprocessor in the battery packet. | 08-26-2010 |
