How Do You Build A Science-Project Electric Car?
The main key for building an electric car for a science project is the weight to power ratio. A vehicle will need to be light enough so as to be able to be moved by a relatively small electric motor. The smaller the motor the less power required to the electric motor, and subsequently, the fewer batteries needed. Step 1 When building an electric car you don’t need to reinvent the wheel so try to use an existing vehicle and simply do a conversion. Find a light aerodynamic gasoline car and take out the engine assemblies. This on its own will significantly reduce the weight. Step 2 There are conversion kits available online and since the cost of these is upwards of a few dollars, then for a high school project it is best to stick to the cheapest ways possible. Surplus aircraft starter motors are 24 volt motors and these are becoming popular to use in small car conversions. Step 3 Remove the combustion motor and replace it with a 24 volt motor. These are available at any aircraft junk yard
