The controller is one of the more expensive bits of an EV. It looks like building this yourself would save gobs of money (a good thing).
The project is still getting off the ground, but a few prototypes have been put together and it looks like it's working well. I'm excited because this hits on all the cylinders of my interest in building EV's:
- It's DIY so I have the pride of building it and I know how to fix it if it goes wrong
- It's cheap
- Did I mention it's cheap?
Once I get the bike to a rolling chassis, I plan on putting one of these together. The idea is that I'll testbed the controller in the bike and either re-use or make another one for my eventual car conversion.
Head on over to Paul and Sabrina's EV Stuff for more information on the controller and some videos of their conversion in motion.
