The EV was not charging, not running, when it self-detonated.
Mercedes, so was high end, well manufactured and expensive. And it still went KA-BOOM!
My ebike battery is fairly small, about two hours worth of riding. So, that might be part of it.
Mercedes cuts corners as bad as others - maybe worse...when I get rid of mine it won’t be replaced by another....
I had read a story awhile back about some of the EVs (don’t know the brand) in China which said it was a premium brand there, but also involved with the most problems. I don’t think it stated what all the problems were, but apparently many of them were just hauled away & not repaired.
