  • Patent number: 11094991
    Abstract: In a battery pack for an electric vehicle, by fixing a lid member to plural fixing portions provided on a bottom wall of a battery case, a cooling medium jacket is formed between a lower face of the bottom wall and an upper face of the lid member. Thickness of the battery case in the fixing portion is formed larger than thickness thereof around the fixing portion. The fixing portion includes a bulge portion bulging upward toward a lower face of a battery module. The lower face thereof includes a recess portion recessed upward, and a projecting portion projecting downward. Since the bulge portion is disposed at a position opposing the recess portion. Accordingly, it is possible to form the cooling medium jacket by strongly fixing the lid member to the lower face of the bottom wall while avoiding increase in the vertical dimension of the battery pack.

  • Patent number: 9583796
    Abstract: A method for determining an operating state (e.g., state-of-charge or state-of-health) and/or generating management (charge/discharge) control information in a system including an electrochemical energy device (EED, e.g., a rechargeable Li-ion battery, supercapacitor or fuel cell) that uses optical sensors to detect the intercalation stage change events occurring in the EED. The externally or internally mounted optical sensors measure operating parameter (e.g., strain and/or temperature) changes of the EED during charge/recharge cycling, and transmit measured parameter data using light signals sent over optical fibers to a detector/converter. A processor then analyzes the measured parameter data, e.g., using a model-based estimation process, to detect intercalation stage changes (i.e., crystalline structure changes caused by migration of guest species, such as Li-ions, between the EED's anode and cathode), and generates the operating state and charge/discharge control information based the analysis.
