The bay is clearly marked out with carriageway text stating "Electric Vehicles Only". Fair enough, but the sign doesn't say that, it just says 8.30am to 9pm Permit Holders Only, with nothing about EVs. If you parked in that bay outside those hours. So it is a complete Dog's Breakfast for a start !!
However, your PCN is for parking outside the bay marking. It is only when one looks closer at the bay that one sees "blips" for presumably indicating individual vehicle bays. This is quite wrong, I think. If the council want to divide up the bay into individual vehicle bays they must make it entirely clear the boundaries of the bays; here they don't. Certainly I think it would fail the definition of a bay marking in:-
Provisions applying to road markings in Part 4. Sign table — Schedule 7, Part 2 the The Traffic Signs Regulations and General Directions 2016 Item 6 Diagram 1028.4. In PART 5 Required or permitted variants 2(4) : -
"(4) The bay may be divided into individual spaces by—
(a)the application of a white line marking (either broken or continuous), with a minimum width of 50 mm; or
(b)contrasting pattern or colour."
If you can obtain and post their photos of the alleged contravention, it would help, but I suspect your photo showing your car with one of those "blips about midway on the car is why the PCN was served, and wrongly in my opinion. However, if you want to win this, you must stand your ground, forego the discount temptation, and be prepared to take them to London Tribunals. Councils in London are venal and rapacious, and they game the system ruthlessly to get the money in.
