    Abstract: A method that includes performing a battery module functionality test on battery cell arrays within the battery module to obtain battery test data for each of the battery cell arrays. The battery test data is used to determine if a measured parameter for one of the battery cell arrays deviates from a predetermined threshold for the measured parameter. A focused secondary battery test is performed on each of the battery cell arrays having the measured parameter that deviates from the predetermined threshold. The battery module is then qualified based on at least one of the battery test data and the focused secondary battery test.

    Abstract: Aspects of the disclosure include systems and methods for manufacturing thermally stable nickel-rich cathodes. An exemplary method can include providing an active material including a plurality of active material particles. The plurality of active material particles include nickel. A nanoparticle slurry additive having a plurality of nanoparticles is provided. The plurality of nanoparticles include one or more of a thermally stable olivine type material, a thermally stable spinel type material, and a thermally stable manganese-nickel dioxide type material. The method includes forming a slurry by mixing the active material and the nanoparticle slurry additive. The plurality of nanoparticles form a thermal inhibitor layer on and in direct contact with a surface of the plurality of active material particles. A free-standing electrode film is formed by calendering the slurry and the free-standing electrode film is laminating to a current collector to define a thermally stable nickel-rich cathode.

    Abstract: Aspects of the disclosure include a roll press design for manufacturing tailored porosity electrodes. An exemplary roll press includes a top roller and a bottom roller separated from the top roller by a gap. At least one of the top roller and the bottom roller includes a raised region and an indented region. The raised region includes a first radius and the indented region includes a second radius less than the first radius. The gap includes a distance selected to accommodate a current collector. The current collector includes a bare portion and a coated portion having thereon an electrode material of a first thickness. A difference between the first radius and the second radius is selected, based on the first thickness, to evenly distribute stress across the bare portion and the coated portion of the current collector during a calendering process for forming a tailored porosity electrode.

    Abstract: A wireless communication system for a vehicle includes a wireless access point (AP), an ultra-wide band (UWB) system, a communication link, a controller, and a vehicle system. The UWB system is in communication with the wireless AP via a communication link. The wireless communication system is operable to detect, via the wireless AP, a request for localized wireless communication. The UWB system requests the wireless AP to generate a clear to send (CTS) transmission, which includes selecting an ultra-wide band (UWB) channel, mapping the UWB channel to a plurality of WiFi channels, and transmitting, by the wireless AP, the CTS transmission to each of the plurality of WiFi channels. The UWB system then transmits a UWB message.
