Gridserve in Peterborough, seems they have upgraded their chargers recently (have used this place a few times)
Wife tried hooking into the chademo unit which was trying to pump 100kW into the leaf which as you'd expect refused the charge, (I got a phonecall about it as she never uses reason when this happens

Suffice to say they got back fine with 7% but drove slowly to make sure.
What went wrong? (i'll have to report it to gridserve y'see) i'm obviously used to faulty chargers but not ones that try to "overjuice" you.
