I have just collected my 2012 Electron with only 11,000 miles on the clock.

As my house has economy 7 I would prefer to charge it after 1 o'clock but when i go to set the charge start time, the off time is adjustable but the start time is always greyed out.

Can anyone explain how to set the start time later than 00.00?

Hi Russ if you do a search I've posted about this before. The key is to set 3 periods peak from 00:00 to 01:00 off peak to 07:00 and peak again to midnight.

Thanks @derekb,

Just in time for me to go out and set it up. Why did they make it so complicated?

Mine's a grey one too.
Cheers

If I recall correctly you can set different weekend schedules too for what, in the UK at least, used to be known colloquially as a pubs and churches tariff. I guess having to program from midnight to midnight each day allows for an easier transition between days on different schedules.

I had to resort to the book to set up my Ampera.

I did wonder want happens when the clocks go forward or back as my cheap tariff window doesn't change with the clocks. In the end, given that the vehicle charges in 4 hours but the cheap window is 7 hours, I programmed for 5 hours and then I don't need to change it when the clocks change.

I am looking to get E7 at my house. From what I understand the clock on the meter does not change for summer/winter so I was going to try and set the car to charge 1 - 5 am GMT which. I think but correct me if I am wrong, will become 2 - 6 am BST.

It depends on the region in which you live and the way the meter was set up. The only way to know for sure is to watch the meter and see when it changes rate. (I'm with Ecotricity, and they had no idea and their best guess was wrong.)

To be honest, it sucks.

No, please don't believe the sticker or the DNO information! Check what your own meter does.

The sticker, the information provided by Ecotricity and the information from the DNO were *all* wrong compared to what our meter actually did and the only answer I could get out of anyone was to stay up all night and watch your own meter to figure it out. If you don't do that, expect your bill to be badly wrong.

Like I said, it sucks. No company seems to own the responsibility for the time range - it's up to the customer to know what their own meter does. They will all point the finger at eachother, but nobody actually knows apart from you.

Hopefully @Mark J Constable can explain why this system is so broken, but there appear to be people replacing meters who don't pay any attention to time ranges.

The best way to understand the on and off time for economy seven is as mentioned above and listen for the click from the time switch as they can vary widely.
Mine changes over to normal rate at 8:30am which I guess means it starts at 1:30am summer time.

BTW, I understood that it charged at 16A when on a wall charge point but I measured mine today with a clip on amp meter at the meter as only drawing 13.5A.

Any ideas why?

Hi Paul,

I know the CC/CV charge profile that LiFePo4 cells require but mine were about an hour from completion and it just seemed to take longer than my other EV's to charge considering it is only a 10kW pack and I was only topping up from 50%.

That damned horn beeping is an annoyance as it beeps twice when the plug is inserted, then when it is withdrawn and re-inserted to start charging immediately, it beeps again.
I know there is a way of stopping it but can't be bothered to muck about powering the charge point up separately.
Just a pity more user choices were not made available.
Fab car though and really fun to drive.
