People will charge their Ampera away from home much less often than a Nissan Leaf owner but you will occasionally want to do it.EDIT:
POLAR have now changed their charging structure and are moving towards a PAYG model so please read this thread with that in mind
However, all charging stations are not the same. Some are free to use, provided free to customers of the establishment such as hotels, B&Bs etc. These are great when statying away from home as you can often travel to your destination and then potter about locally in electric mode.
Of course, if you visiting friends or family just plug in to the 13A socket but be careful to us 6A rather than 10A if it is an old socket or circuit.
Most charging in the UK right now requires some kind of membership. I hate these. You have to join the scheme in advance, usually with some monthy or yearly commitment, and then you get a card or tag. This has a chip inside that allows you to open the flap on the charging station to charge up. No card... no charge!
The whole idea of a membership like this is rediculous. You have to pay for charging you don't know you will need in advance and it is often quite a heafty fee... POLAR for instance wants £29.50 per month plus 95p per charge. Now, given that the Ampera can only charge to about 11KWh and given it can only charge at the rate of 16A max (10A if using the supplied cable), you won't get much per charge. It is an exhorbident cost just to get access to charging.
I don't join a club and pay in advance for my petrol, why should it be any different for electricity?
Please, I urge you all, do not sign up to POLAR or any other charging membership scheme without giving it very careful thought. It could cost you a fortune.
PS POLAR seems the worst but there are many of them cropping up all over the country. It seems that almost every town is getting its own scheme requiring a membership fee and a card. It is simply rediculous and unsustainable.
