RE: Fluence Rate Of Charge?
With Renault cars, you get the Type 2 (Mennekes) lead to either J1772, as you get with the Fluence and Kangoo, or to another Type 2 with the Zoe.
When you plug the J1772 into the Fluence and the other end into a Type 2 connector, the car and the charging station figure out what to charge the car to. So you can plug into a 3 phase 32A Type 2 with your lead, but it would only draw one phase 16A. Basically, if the plug fits, just plug it in.
The 3-pin domestic lead is extra with Renault cars. The ex-press fleet sold off have come with this extra lead, which is an additional £500 or so if it doesn't have it.
If you have to make a decision to buy a 3-pin lead because you can't haggle one out of them for gratis, then I would recommend you don't bother. Instead, find one of the companies fitting these domestic charging stations for 'free' (Government funded) before you actually get the car (else you'd have to wait to charge it up!) and you'll probably never want to use the 3-pin lead again.
Just get the charging station fitted now, if you are seriously thinking about it. Ask for one with a Type 2 socket rather than a flying lead and you can use the lead that comes with the car. Or if you prefer the flying lead then that is up to you, and you need to ask for one with a J1772 plug in that case.
Curiously, the Leafies come supplied with the 3-pin lead, and you have to buy the Type 2 lead. I don't know if that is a marketing plan or not, but ultimately you can do without the 3-pin lead, but not so well without the Type 2 lead. I suspect that means there is a ready market for Leaf owners looking for a Type 2 charging lead.
Just apply for the ecotricity card too. If you find yourself deciding to drive a car a long way, you may have wished to have it sooner. Took about 3 weeks for mine to arrive.
