I think that's what this project does, and the headline is simply misleading. It's not really "blockchain-enabled", it just uses Ethereum for payment.
What else can be inferred from the headline? What would it mean to "put car charging on a blockchain"? Can you explain for the rest of us ?
> the blockchain verifies how much the driver owes
Maybe there's something here where it's pulling external data (e.g. set price/unit or a trusted source that says how much was taken) to decide the price?
