Abstract: A battery assembly is provided. The battery assembly includes a first module having a first plurality of cells and a first voltage measurement device. The battery module includes a sense wire, coupled to a voltage measurement input of the first voltage measurement device and resistively coupled to a terminal of the first plurality of cells. The battery assembly includes a second module having a second plurality of cells and being configured to couple to the first module with the terminal of the first plurality of cells coupling to a terminal of the second plurality of cells via a connector and with the sense wire coupling to the terminal of the second plurality of cells via the connector.

Abstract: The invention relates to a battery assembly with high thermal conductivity. The battery assembly comprises a metal case having a hollow accommodation cavity formed therein, a plurality of battery cores installed parallel to one another within the metal case, and a common electrode for connection to the other electrode in each of the battery cores. Each of the battery cores has two electrodes, with one of the electrodes that corresponds to those of the rest of the battery cores being connected in a thermally conductive manner to the metal case. The invention takes advantage of high thermal conductivity of metallic material and dissipates heat by connecting the metal case to the battery electrodes. The invention further comprises fixation troughs formed on the metal case, thereby reducing the size of the assembly.

Abstract: In a battery pack having multiple battery cells distributed, for example, between multiple interconnected battery modules, a run-time cooling system is provided to cool (and/or heat) the battery cells during routine charging and discharging of the cells (e.g., powering a load such as a motor within an electric or hybrid-electric vehicle), and an emergency cooling system to cool the battery cells in response to a signal indicating detection of one or more conditions indicating possible thermal runaway within the battery cells or battery modules. The run-time cooling system, which may include a fan, HVAC unit or other fluid pumping device, induces continuous coolant flow within the battery pack (e.g., flow of air or other gaseous or liquid coolant). The emergency cooling system, by contrast, includes a mechanical interface or is otherwise adapted to receive a receptacle containing pressurized coolant or other flash-cooling device.
