In my quest to study as much as I can about electric car conversion, I have started looking at the available DIY electric car conversion guides out there, starting with the ‘Premium Electric Car’ guide by Samuel Watson (available online in electronic form). This e-book bears several useful information for the beginner electric car builder or the person who wishes to start a car build from the ground up. The e-book bears a strong overview of how an electric car actually works (like, for instance, what a controller really is) and good techniques to source the batteries, components, and so forth that you’ll require to complete your project. The book is too short to be completely step-by-step in-depth from the ground up, but most DIY’ers will not require that level of detail anyway. It gives you the hard information you require without becoming a canned recipe for car building. Some great extra information is included, though, that probably makes this book worth the money spent. Building a frame from scratch, for instance, or a custom motor mount for your new drive train. The use of deep cycle batteries (instead of less long-lived lead acid or much more expensive li-ion) is covered, which rarely gets mentioned in electric vehicle building.
