  • Publication number: 20240128782
    Abstract: A method for charging a battery pack via an offboard energy source uses an interleaved boost converter and closed-loop control. The energy source outputs a charging current via a DC charge port during a direct current fast-charging (DCFC) process. A controller detects a voltage disparity condition in which a voltage capability of the battery pack exceeds a voltage capability of the energy source. In response to this condition, a rise of the charging current over time is recorded as a current trajectory and an open-loop equivalent time constant is extracted from the current trajectory. A time constant of the PI control block is set substantially equal to the equivalent time constant. The PIM is controlled in closed-loop using proportional-integral control. The charging current is controlled in a continuous current conduction mode during the DCFC process.

    Abstract: Presented are intelligent vehicle systems for thermal event mitigation for enclosed vehicles, methods for making/using such systems, and vehicles equipped with such intelligent control systems. A method of operating a host vehicle includes a resident or remote vehicle controller verifying the host vehicle is stationary; if stationary, the controller detects a predicted onset or occurrence of a thermal event in at least one cell in the vehicle's battery system. Responsive to the detected thermal event, the controller calculates a vehicle parked in enclosed space (VPES) confidence value predictive of the host vehicle being at least partially enclosed, and determines if this VPES confidence value is greater than a preset minimum confidence level. Responsive to the detected thermal event and the VPES confidence value exceeding the minimum confidence level, the controller transmits a command signal to a resident vehicle subsystem to execute a vehicle control operation that mitigates the thermal event.
