The way my go-kart is setup now, i have the fuse on the +48v side of the battery, going to the load. I can move this to the - potential side and share a ground, i dont think that would be a problem.
But yes, currently it is being used high side how it is now. Goal is to measure the fuse on its own, however, to get v-drop across it, determin max v-drop as temp increases before failure, and develop a controls strategy to interrupt the pedal signal to the controller in such a way to run the system at max potential 100% of the time.
I’d like to push 100a or so through this fuse for short amounts of time for better accelerations while maintaining the integrity of the fuse. This is possible, but only for times 1s or less, and its easiest to determine by v-drop across the fuse, unless someone has a better idea
