I think what might actually work would be have part of the price of selling the charged battery price-in an insurance policy for its operation. Fuel stations would take on battery failure risk and have a replacement delivery service, with a rating of how often it gets used. Battery verification using a proof of work or physically unique function (PUF) could be interesting, but subject to the same problems of attestation and verification existing systems have today. If we solved it for batteries, we'd have solved it for everything, so I don't see that happening.
