Hey i was thinking if there is any setup on vesc (or external idk) that when the battery is low it will stop the acceleration but keep the vesc on only for breaking ?? and so if you ran low battery you can push to home but still have to breaking if needed or if you get a hill to regen some battery?
Also i saw some posts but im still not sure about this. What will happened if my board is turned off and i kick push it ? Or if i go down a hill or something ? The current produced by the motor would damage the vesc or not ? And if the vesc is turned on and i kick push the board would this be any different ??
Or all the current will go back to the battery even if i dont break ??
true that but if i give my board to a friend or something cant tell him hey if you drop that much dont use the throttle. I would like to make it safe for anyone and make sure no one can (unintentional) damage the board
Hahaha they wont be friends with me if i dont let them play with this new TOY.
Maybe i dont really understand the cutoff settings. but when it gets to cutoff start it will only reduce the power when accelerating and cutoff stop will stop the board when it gets to that value right ?
How do i detect when it gets to cutoff start ?
If you ride your board till the throttle cut-off engages from low voltage you will still be able to use your brakes on a hill, let me explain.
If we take our boards and coast down a hill the VESC will allow the motors to raise the voltage through power generation and you will have use of your brakes. The motors generate power anytime they are spinning and connected.
The main problem with this scenario is the act of running your battery low on regular basis. It isn’t good for battery health and you could lose control of your brakes due to unpredictable operation.
Alright but when my battery is low as cutoff end the vesc is powering off (or maybe is from bms not sure did not try with higher cutoff from vesc)
SO you are saying that if i set the cutoff end to 3.2V when the battery gets there the vesc will cut all acceleration but wont turn off ? I will have to test this out. When i got my battery low my vesc turned off but that might be the bms.
The VESC never turns off unless it has no power source, the cut-off is only for throttle function. When we coast the voltage will rise if we are going fast enough. I don’t recommend relying on this function but it is how the VESC will behave.
