I would hope this is just poor execution on the manufacturers behalf and will eventually realize that making the battery an upgradable module When does it ever work like this in the real world though? Planned obsolesce and all that. Even in this industry, replacement car parts cost far above the component price when the car was new.

Yes, it's against the interests of car manufacturers to do so. But i could see china encourage that open battery standard(among chinese companies only, behind closed doors) as a way to get market share of both cars and batteries.

Since Musk is not making electric cars just for the profits, maybe Tesla will produce replacement batteries with better specs at lower cost. Tesla cars are designed to have battery packs that can be easily replaced contra Apples recent devices. Tesla car batteries will be the first ones, at volume, that people with electric cars will want to replace. If Tesla sets the trend other car manufactures will be at a disadvantage if they don't follow.

  One of the overlooked cool benefits of EVs imo, is that you can repurpose old batteries, even if they aren't suitable for the EV market. As a battery ages and loses capacity, say it goes down to only 50% of it's capacity when new, it may no longer be acceptable for use in a car but it could still be perfectly adequate as a back up power source in a house.

    Right. So when you are calculating costs, you need to include how much you are going to get for your old battery at usedlionbatteries.com. Of course, the faster new batteries get cheaper and better, the less you old battery is going to be worth.

      That's certainly true but I was mostly meaning to highlight the fact that as these batteries age, and may no longer be suitable for their original purpose, they could still be useful for a whole range of alternative purposes. As the original battery owner I don't intend to get much for selling a used car battery, but it still seems quite cool to have it be repurposed for some other use.
