Well there are a couple of ways you can come with that number. You can ask your dealer or you can just google it yourself.

I'm sure this is not your first rodeo owning a vehicle or buying parts. The price of parts have never had a linear correlation to the actual price or value of the vehicle they represent, so I am not sure why you are particularly doubtful in this case.
Exactly. I could not find anyone who would tell me what they paid for a new battery replacement in the e-Golf. I heard second hand it was about $25000, or more than twice what I paid for the whole car (used). I suspect that the scarcity of batteries and relative rarity of the need (fly out a special team to make switch?) accounts for the unusually high cost. This lead to my rather dumbfounded conclusion that an entirely perfect car, battery aside, could be a complete financial write-off if the battery goes bad out of warranty.
