If you're a consumer in the UK, and thinking about an EV, consider Octopus Energy's Go tariff: https://octopus.energy/go/. They also offer a salary sacrifice scheme to buy EVs: https://octopusev.com/, because this grid-supplementing storage is part of their offering, I think.

Concerns such as, "will my car be charged in the morning -- or for that emergency hospital run?" are considered, I believe, and you can set things like a "minimum charge" with smart chargers.
