Car Breakdown company destroyed my electric car
Discussion
Presumably it is an i3 and was towed with the rear driven wheels on the road.
The permanent magnet motor would generate and if run above base speed could over volt the inverter, if the inverter was not properly powered and weak fielding, to correctly generate.
Just a guess, Max_Torque?

The important question here is what condition the car was in before it was recovered.
If it had already been in an accident things get tricky. The recovery company's insurance will only want to restore it to the condition it was in when they picked it up. I remember a situation a while ago where they dropped a guy's car off the ramp and trashed it and wanted to write it off, but only for the value of an already crashed and unrepaired car.

It needs to either be lifted by all 4 wheels (like those parking recovery ones do) or skates put on the rear wheels. There's no way to put the car in "neutral", so as above if the rear wheels are driven/dragged it could cause damage.
How do you go in those car washes that drag you through?ZesPak said:

Who said anything about a mechanical disconnection? Maybe a point of failure that's generally not needed?

No issues before recovery. (was recovered due to running out of charge).If it had already been in an accident things get tricky.

Yes a relay or contactor would be a sizable extra component to add between the motor and inverter. As would be a mechanical clutch.
Induction motors should be OK I would have thought as presumably they will not spontaneously self excite?
Most EVs with permanent magnet synchronous motors would be OK comfortably below base speed 30 - 40 mph. So OK at 20 mph say. Certainly OK to manually push at walking speed.
I guess the i3 had to be rear wheel drive because of the manufacturer's philosophy. Low to medium power EVs only need the one motor and still makes packaging sense to have it at the front. Then easy to tow with the front lifted.
What damage was actually done?
