  • Publication number: 20230402687
    Abstract: A battery cell includes an anode, a cathode, a liquid electrolyte, and a battery cell case. The battery cell case is configured to house the anode, the cathode, and the liquid electrolyte and includes a case interior wall arranged proximate one of the anode and the cathode, a battery case ceiling, and a battery case floor catching and collecting the liquid electrolyte due to force of gravity. The case interior wall defines a pattern of surface tension varying between hydrophobic and hydrophilic along the case interior wall between the battery case floor and the battery cell ceiling. The pattern of surface tension thereby facilitates self-propulsion of the liquid electrolyte in opposition to the force of gravity and a predetermined distribution of the liquid electrolyte along the battery cell wall.

  • Publication number: 20230398872
    Abstract: Presented are smart vehicle systems and control logic for battery thermal event detection and severity assessment, methods for making/using such systems, and vehicles equipped with such systems. A method of operating a vehicle includes a resident or remote vehicle controller detecting a thermal event in at least one battery cell in the vehicle's battery system and, upon detection, monitoring the vehicle's surrounding area to detect target objects near the vehicle. Responsive to detecting any target objects near the vehicle, the controller aggregates target object data, including a total number of detected target objects and respective proximities of the detected target objects to the vehicle. Using this target object data, a situational severity level is estimated for the thermal event; the controller determines if the severity level exceeds a maximum allowable severity level. If so, the controller responsively commands a vehicle subsystem to execute a control operation to mitigate the event.

    Abstract: A vehicular communication controller includes a microcontroller (MCU) located within a vehicle to publish a newly defined protocol data unit (PDU) including a header and a payload portion to a destination device. The destination device may utilize a first protocol or a second protocol. If the destination device utilizes the first protocol that includes an automotive/embedded communication protocol then the MCU serializes the payload portion of the PDU and binds the PDU to the first protocol. The destination device may then receive the PDU using the first protocol, deserialize the payload portion, and remove the header leaving the payload portion unchanged and recreate, based on the deserialized payload portion, the PDU.
