20100231173 | BI-DIRECTIONAL INVERTER-CHARGER - A bi-directional inverter-charger including a bridge rectifier and DC-to-DC conversion components. The inverter-charger may be connected between an alternating current source, e.g., an AC line, and a direct current source, e.g., a battery pack. The DC-to-DC conversion components may include boost and buck circuits that are switchably configured between a charge mode and an inverter mode such that common components are used in both charge and inverter configurations. In the charge configuration, a full wave rectified signal from the H-bridge is up converted by the boost circuit, and the buck circuit controls charge current to the direct current source. In the inverter configuration, the boost circuit up converts the direct current voltage source, and the buck circuit controls the current and its form to the bridge circuit so that the bridge circuit may be connected directly with the AC source. | 09-16-2010 |

20120223582 | CELL MODULES FOR DETECTING TEMPERATURE AND VOLTAGE OF CELLS - Disclosed is a distributed battery management system that uses cell modules that are attached to cell terminals. A connector tab extends from the cell modules that provides a solid thermal and electrical connection to a cell terminal, as well as structural support for the cell module. A single wire is used to connect the cell modules that carries power, a voltage sample level, a serial data stream, indicating the temperature at a cell terminal to which the cell module is connected, and voltage level of each of the cells, as well as discharge current to equalize the charge of each of the cells. Various adapters can be used for different cell formats, which provide structural support for the cell modules. Reverse connection protection circuitry is also provided that protects the circuitry in the cell modules from accidental reverse connection. | 09-06-2012 |
