I’m using a flipsky 75100 for an 6000w e scooter build (I’ve only got one of 2 controllers at the moment), but I’m weirdly getting readings of 45 amps, and only 200w. It’s weird, because that would mean that the voltage to the motor is 5v, even when the battery im using is at 68v. I’ve been screwing around with the settings in vesc tool for most of the day, and I can’t seem to get past 200w on my 3000w motor.
its a 16S 8P 38AH battery. peak voltage is 67.2.
I’ve just set them to the calculated 16S limits, and nothing has changed. It’s weird, because there is no way that it’s drawing 45amps and only that powerful.
Electric motors don’t produce power at zero speed (neither do gas engines for that matter).
Power is speed * torque.
That 200W is being dissipated as heat inside the motor.
Motor controller steps down the voltage and regulates current through the motor, so yes, the motor is only seeing 5V because if it saw the full 68V it would melt and catch fire.
I suspect you also have sluggish acceleration, but that a completely different can of worms.
My motor is set to 45A and so is my battery. the weird part is that there is no way that is is drawing 45 amps and I can hold it back with my hand. The battery voltage was at 68v, so it should be able to deliver 3000w, but somehow its stuck at 200w, but still draws 45amps??
Not sure what’s up with these units. They were designed by some guy as a hobby project and then copied by flipsky… till very recently flipsky didn’t even have acess to the firmware sources. It was the community that somehow organised the source files, so that firmwares can be compiled.
