Vehicle caravan of electric vehicles configured for coordinated movement and airflow control and method of using

A method of airflow control for a vehicle caravan of electric vehicles, comprising:

• forming a vehicle caravan comprising a plurality of electric vehicles configured for coordinated movement and airflow control, the vehicle caravan comprising:
• a lead electric vehicle and chase electric vehicle, the lead electric vehicle configured for disposition at a front of the vehicle caravan and configured to lead the vehicle caravan when the vehicle caravan is moving, the chase electric vehicle configured for disposition rearward of the lead electric vehicle in a chase pattern to follow the lead electric vehicle when the vehicle caravan is moving, each lead electric vehicle and chase electric vehicle comprising:
• a vehicle chassis extending along a longitudinal axis and a rotatable vehicle drive axle disposed along a transverse axis as a front axle and having opposed axle ends that are configured for attachment of a pair of opposed drive wheels;
• and
• a selectively movable electric propulsion motor comprising a rotatable motor shaft rotatable about a motor axis, the selectively movable electric propulsion motor configured to be mounted within the vehicle chassis and operatively coupled to a rotatable vehicle drive axle and opposed drive wheels, the selectively movable electric propulsion motor and the motor axis configured to be oriented in a substantially vertical direction and movable with reference to the rotatable vehicle drive axle from a first position comprising a first direction of the motor axis to a second position comprising a second direction of the motor axis, the second position being separated from the first position by an angle (α), the selectively movable electric propulsion motor configured for air cooling from an airflow received from a vehicle front of the electric vehicle;
• an air duct disposed within the vehicle chassis that extends from a front end proximate the vehicle front to a motor end proximate the selectively movable electric propulsion motor and configured to direct the airflow to the selectively movable electric propulsion motor;
• a selectively openable and closable airflow shutter disposed proximate to and in fluid communication with the front end of the air duct and is configured to selectively control the airflow within the air duct;
• and
• a vehicle controller that is configured for coordinated control of a motor position and a motor axis direction of the selectively movable electric propulsion motor and an open or closed position of the selectively openable and closable airflow shutter with each other electric vehicle in the vehicle caravan;
• the vehicle caravan and chase pattern configured for coordination of the motor position and motor axis direction of the selectively movable electric propulsion motor and the open or closed position of the selectively openable and closable airflow shutter of the lead electric vehicle and the motor position and motor axis direction of the selectively movable electric propulsion motor and the open or closed position of the selectively openable and closable airflow shutter of the chase electric vehicle while the vehicle caravan is moving;
• and
• controlling the airflow of the vehicle caravan while the lead electric vehicle and the chase electric vehicle are moving.
