Hi all. New to this hobby and this forum -- thank you all for the great conversations I've lurked and read.
I'm looking to develop a small EV experimentation platform, with the goal of being able to support anywhere from one to four motors, in various go kart / buggy / moped / other configurations.
I've got big picture questions:
I'm looking to develop a small EV experimentation platform, with the goal of being able to support anywhere from one to four motors, in various go kart / buggy / moped / other configurations.
I've got big picture questions:
- Are there best practices for multi-motor configurations? Should I be looking for single batteries that have the amperage to drive all motors (perhaps one battery for 1/2 motors and another for 3/4, just to optimize for size and weight on smaller experiments)? Or is it cleaner to do one battery per motor? If one-per, is it wise or dumb to connect in parallel to share load/recharge?
- Is there such a thing as a multi-channel speed controller that can drive multiple motors at independent speeds (e.g. turn outside wheels faster on a corner)? I'm not turning them up in searches, but may not know the right terminology
- Are there off-the-shelf ECU type microcontrollers that provide Arduino/etc programmability with the hardware for canbus, hall type outputs, etc? Or is everyone doing homebrew for the microcontrollers?
