Motor Controller Burns EV Duster

Posted February 10, 2009 12:00 PM by CarDomain

I was just checking out Bruce's EV Duster blog and it looks like his motor controller blew up recently, causing a small fire under the hood. Luckily there was no real damage to the car or other components. Here's what Bruce had to say.

"I spoke with Jim, the owner of LogiSystems this afternoon and thoroughly discussed my controller issue. He did a post-mortem on my controller and found that it had a catastrophic failure. Duh! He said that it was the most badly damaged controller he has seen, even among the ones they have deliberately failed as test units.

My controller was too badly damaged to know exactly what went wrong, but he said it looked like a direct short of full battery voltage/amperage across the main busses - which should be impossible in the controller."

Yeah..my designs sometimes have those faults too
That's the problem with Electronics...it's easy peasy
...in theory.

A direct short on that lot! Lucky it didn't melt the whole car
