Hi everyone,
I am a newbie, in the process of buying my first electric car. I have been reading your forum for a few weeks, trying to learn and understand the ins an outs of owning an e-car.
One question that worries me a little, and for which I have not found an answer is :
What happens to the battery charge if I leave my car in a long-stay car park at the airport, for 1 week or even 3 weeks?
I saw comments that it is important not to leave the car 100% charged for a long time, and the same for 10-20% charge. What is "a long time" ? A couple of days? A couple of weeks?
I am guessing that for airport parking I should make sure the battery is 50-80% charge. After 3 weeks, will I need to rush to charge it before driving home?
TIA,
Steve

Welcome!
In terms of the traction battery it will be fine. Some EVs have vampire drains such as a Tesla M3 in Sentry mode where they'll lose up to 1% a day at most, but left at say 80% it'll still be at 60% after 3 weeks.
In common with other modern cars but to a lesser extent the 12v will run down, but unlike ICE most modern EVs will recharge it automatically.
So in summary it is less likely to be a problem than an ICE. Next time you go to a long term airport carpark look at the issue with JLR ICEs. :eek:

Thanks for the information. That sort of figure is quite acceptable. I live about 50 miles from Heathrow, so the return trip home should not required recharging. (looking at e-208 and zoe for the moment)

You won't have a problem with either of those. In some cases the SOC can go up after you've left it parked.

An increasing number of parking firms have fast charging points and will stick it on charge for when you are due home for a reasonable fee so that you can be fully charged to go home. You risk the car being left at a high SoC if you are significantly delayed but that's no big issue in the scheme of things.

In Ampera I got Gatwick valet to charge, but didn't with Zoe as charging flap is a bit fragile and had visions of them breaking. We used 22kW post at Gatwick short stay to top up (to around 90%) and then drove to valet section. We were away over 3 weeks and all was fine on returning. The car stopped reporting charge level after about a week, probably to preserve 12V battery.

I forgot that. Ditto with the LEAF but I got a text when it was moved (presumably to be charged) which was reassuring even if meaningless (it could equally have been twoc'd, but who'd steal a LEAF24 given the choice of other cars - unlike a previous Subaru that went for a Saturday night out before fortunately returning).
