That is my understanding too. I may not have explained well but yesterday only one of the two plugs were being used at any one time. The CCS/Chademo charger did have 2 cars plugged in but only one car was able to charge at any one point. I anticipate this will change following the software update. I was impressed by the length and flexibility of the cables at the new Gridserve chargers, but in many cases it will not be physically possible to park in such a way as to use all available plugs.Hi,
I was under the impression that for now only 1 charger per Machine can charge at any one time. They are awaiting a software update, who k kws when, that will then properly balance the charges according to each car needs.
I agree it does not explain why they all went down, but might explain why you could not charge at the same time on same machine.
