While on the surface that sounds like a lot of money, its important to remember that current model Teslas are premium products and are priced accordingly. More modest EVs, with their smaller packs, will be much more economical.
For example Chevy has said they've gotten the pack price for their upcoming Chevy Bolt down to around $145/kWh, since they're planning on a 60kWh pack that works out to about $8,700 for the pack - after "profits" they'll probably sell replacements for 10k. That sounds like quite a bit, but when you consider that the pack should provide a usable lifetime range between 6-8 years its not that bad.
* At 6 years that's about $1,666 annually, or $32/week.
* At 8 years that's about $1,250 annually, or $24/week.
Granted your experience will differ, for me its about $1 daily to fill up my 2015 Nissan Leaf since I don't drain the battery to empty. I'd expect a similar experience even if the pack size were larger than the current 24kWh pack I have. I've owned the Leaf two years now and I've spent perhaps, at most, $600 to fuel my car - or about $300 annually or $5.75 weekly. So using the examples above that takes the "fuel" costs up to:
* 6 years = $1,666 + $300 = $1,966 or $37.80/week
* 8 years = $1,250 + $300 = $1,550 or $29.80/week
When I drove gas I spent upward of $40/week, about $2,080 annually, in fuel. When I consider the maintenance I'm no longer doing - oil changes, spark plugs, various belts, transmission, etc... - along with the cheaper insurance, my rates actually went down and I'm now paying about $75 monthly on a brand new car!, it works out to be cheaper overall. All in, without digging out my old receipts and doing the math, I was easily at least $50-$60 weekly ($15k-$25k total over 6/8 years) keeping my gas car running.
However unlike a gas car which has these charges spread over the 6 to 8 years, making it easy to not notice them, when the time comes to replace the pack in an EV you pay it all out at once and this makes it looks like an expensive vehicle to maintain. Granted it is a lot of money to spend at one time on a car, but Total Cost of Ownership between EVs and Gas over time have no contest - EVs are far cheaper over the long term to maintain and run than a gas car. The biggest expense on EVs are tires, brakes, suspension, air conditioning, and the battery pack. Brakes seldom need to be replaced due to regenerative braking, tires are tires - everyone replaces those, and suspension and AC are just parts of the standard vehicle maintenance. But all the rest that comes with owning an ICE engine you just don't have that and you couldn't pay me to go back, I've got better things to spend my money on.
And this, of course, assumes that you're going to replace the pack after 6-8 years. If the degraded pack still meets your needs, you can continue to drive on it until it doesn't. Additionally the battery tech is getting better all the time, so as the technology improves replacements will get cheaper and existing packs in newer vehicles will maintain their usable life for longer periods - the TCO will just get lower.
