"So much for electric cars from a NZ mechanic!"
Had to work on a "Nissan Leaf" last week. A $30,000 car with a crook battery.
No-one in town would work on it and as he had done a course it was given to him.
He got the tutor up from Dunedin polytech to help.
One crook module in the battery was shorting to the case.
A secondhand module is able to be fitted, but they need to be in exactly the same condition as the remaining ones (85.2%) or the entire battery fails.
So the owner was left with the option of a secondhand battery out of a wreck that has no guarantee at $14,000 or a new battery at $20,000.
Then there is the problem of disposing of the old battery or part battery.
Nothing available and No-one willing to transport a damaged battery.
Specialist transport is available, and the cost to have one module (out of 24) transported to Australia and disposed of is around $5,000.
On top of all that, the tutor went through some of the legislation around EV's with him. So if one is involved in a crash, and people are trapped inside, the fire brigade have to isolate the battery before they cut into the car.
In a “Leaf", the isolation plug is under a bolted cover on the floor between the front and back seats.
Once the cover is removed, the 3 pairs of gloves required by law are to be fitted, cotton, rubber, and leather.
Then with hands resembling lamb roasts they can try and disconnect the 3 stage electrical plug.
Then they can cut into the car.
So the problem with crashing any electric vehicle is that if you are trapped, you're dead, as it is impossible to remove victims.
