Not even close to the same amount of work. Replacing the battery pack in my PHEV, should it ever need replacing, which I doubt, involves removing 20 bolts and unplugging it. It drops right out the bottom of the car.
Ok, so stories like the guy who blew up his Model S because he was told a new battery would be $22,000 leave me not knowing what to think.[0]
Our official car dealer would happily try and charge $50 to refill the windscreen washer fluid during a routine service :) so maybe the actual cost of the battery unit is only part of the story here.
$22k for a Model S battery doesn't sound very wrong to me, but it's going to be almost all materials and not a lot of labor. The battery I mentioned lists for $5500 from Honda, and it is only 17 kW-h. A Tesla has a 50-100 kW-h pack, so I would expect the cost to be proportionately larger, with a slight discount given Tesla's large battery purchasing power.
