Is that where the voltage spike comes that kills?
Basically all sudden power shifts will cause transients
Seems like vesc transforms the voltage in anything a step higher than the current battery voltage. I can brake with a full pack and i see voltage go to 53v in vesc tool.
Cheap components or a battery that can’t absorb this energy, or long battery wires, or not enough capacitors will make that regen voltage shoot though the roof for a few moments. Sometimes just enough to blow stuff up.
Truth is vedder can make a 500V esc, we’re still going to find a way to use it at 490V and cry when a voltage spike physically blows it up
If the battery isn’t fully charged…
Transient energy is proportional to the square of current from parasitic inductance.
This causes a massive voltage overshoot that blows up the high voltage well on the MOSFET driver.
well that certainly cleared up any brain-clouds i had…
thanks , Kai!!!
