E7 doesn't change with BST. It runs 11:30 - 6:30 GMT (ish) all year so you just leave the timer on GMT too.
My car does change time though, so I have to remember to change its idea of start time, and all my schedules (3rd party tool)

For schedules I have:

Drop limit 10% at start of E7
Re-raise limit back that 10% an hour before departure (that is before E7 ends )
Re-start charging at that time (in case stopped)
Stop charging at end of E7

Much simpler for me.
I don't tell the car to do anything - just leave it plugged in and if it detects power at the socket, it starts to charge if it needs to. GMT/BST is irrelevant.

The trouble with charger-controlled timing is that it doesn't support pre-conditioning of the car without manual intervention (to overide the timer on the charger)

On the other hand, if you've got solar (or other self-generation), setting a timer from the car won't allow the use of any surplus power at other times.

My charging regime will obviously adapt to PV and a Zappi. No point paying even night rate if the car can top up for free.

:)

Lots of variations ... I'm happy being an early adopter, but not everyone is of course, and there are loads of these sorts of snags. Software could take care of all of it, but no Vendor going that extra mile (that I know of ... yet).

Maybe WattCat is the answer ...

Rooting for you on that one.

Do you (or "will you") get any realistic EV charging in Winter?

I don't attempt to do that because car is at work during the day (Work is planning on putting a major PV installation in soon), but my Home PV generation is 10% in Winter of what I get in Summer (i.e. UK latitude)

Listed building, so having to jump through a few more hoops to get approvals. Probably be next Spring now as I'm not too keen on them removing the roof during the Winter. (Getting the garage re-roofed with in-roof PV)
