This research aims to evaluate and present the aerodynamics of future electric cars. There are a number of design challenges associated with creating electric vehicles but continuous research and development has the potential of solving these problems with the added use of innovative design techniques…
The researcher states that changes in global demand patterns, market forces, environmental concerns and the ever present danger of fleeting fossil fuel reserves are forcing automobile manufacturers and research scientists to look for alternative means to fuel automobiles. One facet of these developments has been electric vehicles that are powered exclusively through electric batteries. The emergence of electric vehicles has put in motion a number of new design challenges such as the aerodynamics of such vehicles because aerodynamics represent a large loss during normal functioning of all kinds of automobiles. Drag created by a moving vehicle represents one of the largest losses of energy created by an automobile’s engine. Conventional automobiles may lose as much as 40% of the total power to air drag. As with other conventional bodies, the aerodynamic drag exerted by air on a vehicle is directly proportional to the square of the velocity of the vehicle. For typically aerodynamic automobiles the coefficient of drag and the accompanying area need to be as small as possible in terms of design considerations in order to minimize the drag encountered. There has been an ongoing struggle to create vehicles with as low a coefficient of drag as possible. Typically well designed vehicles display coefficients of drag of the order of 0.13 while a coefficient of drag of 0.1 is achievable through special design considerations. ...
