  • Patent number: 11616277
    Abstract: A battery that includes collectors with tabs that are wide with respect to the area of the collector. The wide tabs present a low electrical and thermal resistance to improve the flow of current and/or heat to and from the collector thereby improving electrical and thermal performance of the battery. The battery further includes terminals with a channel that supports the flow of medium (e.g., liquid) to heat and/or cool the battery. The terminals may include fins or pins to increase the surface area of the terminal to improve thermal transfer to and from the battery and collectors of the battery. The batteries may be formed into a battery module that includes a system for monitoring and regulating the temperature of the batteries of the module.

  • Patent number: 11611118
    Abstract: A method for assembling a traction battery for an electrically operated vehicle, in which at least one battery module is inserted into a battery housing in a module setting process, with the formation of an air gap between the battery module and a housing base of the battery housing, which is filled with a highly viscous thermal paste, which builds up a viscosity force due to internal friction when it is distributed in the air gap, which acts on the housing base until the thermal paste is distributed in the air gap by the flow of material and the accompanying reduction in the viscosity force. The housing base is supported on its housing base lower side by a counter holder in order to limit a deflection of the housing base due to the viscosity force of the thermal paste.
