  • Method of making a battery cell including clamping, tapering, trimming and ultrasonic welding of electrode foils
    Patent number: 12136747
    Abstract: A method for manufacturing a battery cell having electrode foils protruding from a cell pouch includes positioning the cell pouch in a fixture such that distal end sections of the foils extend outward from the fixture. The method includes clamping the distal end sections in a curvilinear guide clamp to cause the distal end sections to taper into an electrode foil stack, and then translating the clamp a predetermined distance toward the fixture to displace the distal end sections by the predetermined distance. The method also includes trimming the distal end sections using a trim tool, positioning a sonotrode and an anvil adjacent opposite surfaces of the stack, and ultrasonically welding the stack to a conductive lead tab using the sonotrode to thereby form a welded joint within the battery cell. The sonotrode may be multi-sided with different knurl patterns for performing different welding processes.

  • Hairpin conductor for an electric motor stator and method of forming the hairpin conductor
    Patent number: 12136856
    Abstract: A hairpin conductor includes two wire segments each having respective first and second ends and a respective middle region. The segments are disposed in a side-by-side orientation such that their first ends are proximate each other and their second ends are proximate each other. The first ends are welded to each other and the second ends are welded to each other, or the middle regions are welded to each other, thereby providing a welded wire assembly, which is bent such that the two wire segments are bent equally to form the hairpin conductor. The hairpin conductor has a primary bend in the middle regions to form an apex thereat and first and second secondary bends in the two wire segments nearer to the apex than to the first and second ends to form respective first and second shoulders thereat. A method of forming the hairpin conductor is also presented.

  • Protocol for discharging DC power from propulsion battery pack to offboard charging station
    Patent number: 12134332
    Abstract: A method for coordinating a discharge session in which direct current power is offloaded from a power supply, e.g., of an electric vehicle (EV), to a bidirectional offboard charging station includes, in response to connection of the power supply to the charging station via a charging cord set, exchanging charging data between the EV and charging station. This occurs over a low-voltage communication line, with charging data including power and current limits of the EV and charging station. In response to the limits being indicative of negative limits, with the negative limits representing a request for the discharge session, the method includes transmitting the EV power and current limits to the charging station to confirm the request. The discharge session is initiated in response to confirming the request through an exchange of a unique identifier indicating support for the discharge session.
