Abstract: A system, for use in evaluating operation of a vehicle, includes a hardware-based processing unit, and a non-transitory computer-readable storage component including various functioning modules. The modules in various embodiments include an input module that, when executed by the hardware-based processing unit, receives, from a vehicle-braking sensor, braking data indicting characteristics of a braking event at the vehicle. The system in some implementations includes an input unit receiving the braking data from the sensor and passing it to a braking-monitoring module. The braking-monitoring module, when executed by the hardware-based processing unit, determines, based on the braking data, whether the braking event is within an acceptable pre-established limit. The technology in various embodiments includes processes performed by the system and algorithms used therein.

Abstract: Presented are thermal management systems using coolant flow distribution plates for immersion cooling of battery cells, methods for making/using such systems, and vehicles equipped with such systems for cooling the vehicles' battery packs. A battery assembly includes multiple battery cells arranged in adjacent, mutually parallel cell rows. The battery cells are stored inside a protective battery housing that includes inlet and outlet fluid ports for receiving and evacuating therethrough dielectric coolant fluid. A pair of (first and second) separator plates is located between each neighboring pair of cell rows. Each plate includes coolant channels that are arranged in mutually parallel channel bands. The separator plates are in face-to-face contact with each other such that each channel band of the first separator plate is aligned with a respective channel band of the second plate so the coolant channels cooperatively distribute coolant fluid onto and vertically upward between the battery cells.

Abstract: A cooling system includes a housing including a base portion with sides and a bottom surface that define a cavity and a cover portion to enclose the base portion and including cooling members attached thereto. A shield is arranged in the cavity. A vertical member is arranged below the shield to define a first fluid chamber between one side of the vertical member and one side of the base portion and a second fluid chamber between an opposite side of the vertical member and another side of the base portion. The electronic components are arranged in the second fluid chamber. Cooling fluid is arranged in the cavity and has a fluid level below at least a portion of the shield. The housing is mounted at an inclined angle relative to horizontal or the housing is mounted parallel to horizontal and the shield is mounted at the inclined angle.

Abstract: A battery cell thermal conditioning system for a vehicle includes a battery pack having multiple battery cells. Multiple foam layers are individually positioned between first successive ones of the battery cells. A first carbon nanotube sheet is positioned in direct contact with one of the battery cells on a first side of the foam layers and a second carbon nanotube sheet is positioned in direct contact with a different one of the battery cells on a second side of the foam layers. A cooling plate is positioned between second successive ones of the battery cells. A controller directs current flow to the first carbon nanotube sheet and the second carbon nanotube sheet when a temperature of the one of the battery cells contacted by the carbon nanotube sheet drops below a predetermined threshold temperature.
