EV-HEV Intake Generator and Braking System

EV-HEV Vehicles are designed to minimize drag and optimize energy consumption, increasing mileage.

To achieve this, the body has to be designed to have low air flow resistance and to recover most of the

energy in a brake event through regenerative brakes.

To improve energy usage in an EV-HEV vehicle it is possible to include an active flap system that can

minimize drag and maximize energy recovery in a braking event using the high velocity of the air flow.

Proposed Solution


While driving at high or low speed the flaps are closed providing a sharp front fascia improving

aerodynamics of the vehicle reducing the energy required to move. (Fig. 1)

When the gas pedal is released at high speed the regenerative brakes step into action, and the car

begins to slow down. If the brake pedal is applied, the flaps vary its angle to allow the air flow to enter at

the system. Once the air flow passes through the flaps it enters to a nozzle that increases its velocity.

Then a generator extracts the high energy of the moving air and recharges the batteries. Finally, the air is

released though a couple of pipes to the exterior of the car. This process increases the drag in the car,

helping the stop maneuver. (Fig. 2)


This solution would be good for high speed driving conditions, since it is the environment when the air

flow has a higher amount of energy due to the car’s velocity. Flap surface should be designed to work
