Over the timespan in which you'd have to replace it, and given future cost reductions in battery production, it's probably the same as the total cost of maintenance for a petrol car. The cost of getting a petrol car to 100k or the 10 year mark isn't cheap. Even a Toyota is going to run you like $5k. A BMW or Benz, probably closer to $15k. If you buy a used BMW 3 series for $20k today and keep it for 10 years the cost of maintenance + gas will be well over $20k. A lot of people greatly underestimate the total cost of ownership for a petrol vehicle. Best case scenario is you have to replace every moving part that isn't the engine itself. Worst case scenario is you have the replace the engine too.
