Systems and methods for ensuring drivability for battery electric vehicles during extreme cold weather conditions
16 Jan 24
A battery control system for a battery electric vehicle is configured to detect that a driver door of the vehicle has been opened and connect the battery system to an electrical system of the vehicle to power at least a cabin heater and defroster of the vehicle, detect a driver start request, determine whether a set of battery parameters satisfy a threshold indicative of the battery system being sufficiently conditioned for driving of the vehicle, and when the set of battery parameters satisfy the threshold, display, via the user interface, a first message indicating that the vehicle is ready to drive and allow the driver to drive the vehicle and driving is prevented.
