My Kelly HSE 14801 for SepEx (kostov 9'' 120v). Blown up from the inside...
what could it be?
It was programmed at 25% and regen. It was taking 120 Amps maximum.
I made a test whit the car, and after arriving to the garage, turned it off. Gone to my living room left the things over the sofa, came back to the car to put in the garage. Turned it back on, the car slided back a bit (i live on a hill), pressed the throttle and the circuit breaker turned off. Something wrong appened, so I followed all the cables and terminals to see if something was wrong, found nothing. Turned the circuit breaker back on. After turned the key on, the controller made an explosion and a lot of black smoke came from its inside.
Before that test it was at 20% of it's power and also I tested it more than one time.
I see people complaining about his controllers. Or it was my fault?
I was thinking about many possibilities to have caused this:
- Because the regen function was activated, and the car was sliding back, pressing the throttle might have shorted something?
- Bad insulation from kelly assembly to the chassis of the car, I mounted the kelly assembly (comes in a metal plate) directly to the structure I made.
- I live on the top of a hill, it was taking 120 amps continuously to climb during 3 minutes before arriving home. Turning back on with the controller hot maybe have caused any problem.
- Opening the controller by myself and trying to fix it, because I lose the contact from kelly.
- Buy a new controller that is rated for my battery pack 120v 100AH HiPower.
- Or send it back to Kostov to wire it in series... more easy to find controllers.
I read somewhere that if F1 and F2 where disconnected it can send all the power to the motor, is it true? The F1 and F2 are connected but if it disconnected for an instace? Does the controller motorize it?
