Putting aside the obvious fixes for things not currently working, some ideas wot I thinked of
- Max charge on timer; e.g. weekdays charge to 80%, weekends stick a full charge on.
- Location based timers; e.g. if I'm at home use the Go tariff times. If I'm out and about, at tesco taking advantage of a free top-up, do an immediate charge.
- Charge rate visible.
