Claim 7:
8. A battery control method for a battery electric vehicle, the battery control method comprising:
communicating, by a controller of the vehicle, with a set of sensors configured to monitor a set of battery parameters of a battery system of the vehicle, the set of battery parameters including at least a state of charge and a temperature of the battery system;
detecting, by the controller, 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;
detecting, by the controller, a driver start request and powered propulsion systems and enable driver control of the cabin heater and defroster of the vehicle;
determining, by the controller, whether the set of battery parameters satisfy a threshold indicative of the battery system being sufficiently conditioned for driving of the vehicle;
when the set of battery parameters satisfy the threshold, displaying, by the controller via a user interface configured to receive inputs from a driver of the vehicle and display messages to the driver, a first message indicating that the vehicle is ready to drive and allow the driver to drive the vehicle;
when the set of battery parameters does not satisfy the threshold, displaying, by the controller via the user interface, a second message that the vehicle is not ready to drive and should be plugged-in to an external charging system for conditioning of the battery system;
in response to the vehicle being plugged-in to the external charging system, allowing, by the controller, driver control of the cabin heater and defroster until the battery system is sufficiently conditioned; and
displaying, by the controller via the user interface, a third message indicating that a drive request maneuver is not allowed and a drive start disablement state.
