Not surprising given the drastically reduced number of moving parts in an EV Powertrain vs an IC Powertrain.
Interestingly though I suspect the high percentage of battery related issues will in turn manage to keep the average maintenance bill at about the same. Granted that's a problem likely to be fixed with improved battery technologies and the reduced frequency of problems is worth something in itself.
I want one billionair who has enough of this bullshit and starts a company that builds stuff to last. It would be a goldmine, I'm sure. Because if people build trust in this brand they will gladly pay a good price for cars, dishwashers or printers that are durable and easy to repair.
Or do we have to do this by ourselfs somehow?
The 44.1% battery failure figure is regarding the "starter" battery (12V) and is combined from all vehicles in the study (EV and ICE).
The HV Battery for the traction drive is grouped together with any kind of motor failure and comes in at 22.8 %. But this figure also includes ICE vehicles ejecting piston rods etc.
The only EV vs ICE numbers stated directly are the total breakdowns per 1000 vehicles at 1.9 (EV) and 3.6 (ICE).
I'd be really interested in a chart showing the failure categories separated by EV and ICE.
