Abstract: Presented are active thermal management (ATM) systems with multi-purpose reservoirs for liquid-immersion cooled battery assemblies, methods for making/using such systems, and motor vehicles equipped with such systems. An ATM system for a battery assembly includes a coolant reservoir that stows a liquid immersion cooling (LIC) fluid, and an inlet manifold that fluidly connects the reservoir to the battery assembly's battery case to transfer LIC fluid into an immersion compartment within the battery case. An outlet manifold fluidly connects the battery case to the reservoir to transfer fluid out from the immersion compartment. An auxiliary vent manifold selectively fluidly connects the battery case to the reservoir responsive to a predefined thermal event to thereby transfer LIC fluid and battery cell vent gases from the immersion compartment to the reservoir. A gas valve, which is fluidly connected to the reservoir, selectively evacuates therefrom the vent gases at a predefined internal reservoir pressure.

Abstract: Presented are intelligent vehicle systems and control logic for adaptive vehicle sensing and automation for occupants with health conditions, 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 determining an existing health condition of an occupant in the vehicle's passenger compartment. The controller then retrieves, e.g., from a resident or remote memory device, predefined sets of calibration settings and condition symptoms customized to this existing health condition. A network of sensing devices is calibrated using the predefined calibration settings to detect one or more of the predefined condition symptoms. The calibrated sensing devices monitor the occupant to detect a health event based on the predefined condition symptoms. Upon detecting the health event, the controller commands one or more resident vehicle subsystems to execute one or more vehicle operations to mitigate the health event.

Abstract: A battery electric system includes a battery, sensor suite, and controller. The sensor suite includes a current sensor, voltage sensor, and temperature sensor. The controller is operable for determining an estimated open circuit voltage of the battery at different time points using a current signal and a voltage signal from the current and voltage sensors, and an equivalent circuit model (ECM). The controller determines an ECM-based state of charge (SOC) of the battery at the different time points, via a calibrated SOC map, using the open circuit voltage and temperature, and calculates a sensor gain value using the ECM-based SOC and a coulomb counting-based SOC, both at the different time points. A control action is executed with respect to the battery when the sensor gain value exceeds a predetermined gain fault threshold, including generating a fault notification signal indicative of a fault of the current sensor.
