ANOTHER LONG POST: This post describes 3 weeks of testing that was done with the newly built controller power board. This is the power board that I wrote about in this post. We are planning to use this (or at least try it) in the truck if all our testing works out. For the controller logic board, I am using the Stellaris microcontroller evaluation board for the brains, a partially built DIY controller (see this post) for the analog circuitry, and a plug board for a half-bridge low-side/high-side driver. So even though the power board is looking good, this whole system is still very much a prototype. I am working on a circuit design and board layout for the logic part of the controller, but it will be a while before that is finished.
Testing of the power board was done in 3 steps:
- tested on a bench with a bench supply and limited current
- tested on the Kart with the battery pack but with no load on the Kart
- tested using the new controller power board to drive the Kart
Bench testing the new power board with ADC motor
