Free Traffic Legal Advice

Hello,
This is a case of ridiculously bad timing and luck for me. I was in Kingston today to pick up my wife and my son from his music school for some shopping and also intended to charge my EV. When I parked in the designated EV charging bay, I realised my wife had my Electroverse EV charging card, so I popped out of the car to go in and find her. When I came back about 10 minutes later I already had a PCN as I started to charge my car! I am wondering now if I had been watched by the Warden before he decided to pounce.
I attach:

Proof of EV charging (invoice), I charged the car while were out and about: https://ibb.co/0VDtsLY

“Challenge grounds” that the Council provides: https://ibb.co/gPwxq8Y

I would like your view if I have grounds for appeal given that I was only momentarily gone to pick up my charging card? Yes I could have phoned her to come to me with the charging card, but my son is only 4 and they want at least one parent on site to supervise.
Also, some of the ‘challenge grounds’ seem a bit loose and were picked up on by @Hippocrates in two other posts from September here https://www.ftla.uk/civil-penalty-charge-notices-(councils-tfl-and-so-on)/new-malden-code-73-parked-without-payment-of-the-parking-charge-malden-centre-ca/ and here https://www.ftla.uk/civil-penalty-charge-notices-(councils-tfl-and-so-on)/kingston-code-232-parked-in-a-loading-bay-canbury-park-road/msg38370/#msg38370 .
“The order was invalid” – this won’t mean anything to a lay person, what order? “The penalty charge exceeded the amount”, what amount are they talking about? How am I supposed to know what this means without spending plenty of time researching?

Did the CEO take any photos?

Did you connect the car and charger before you realised?

On the electroverse app you can start charging without needing the card.

Hello,
Yes the CEO took photos with time stamps of 14:14 and 14:15. No photos
from the start of the observation which the PCN alleges was at 14:04.
I started my charge at 14:18 as shown in the earlier invoice so just missed him.
I parked and I did not plug the car in to ‘pretend’ I was charging (that would surely deserve a fine!), as I was in a rush to go in and get the card.
I normally charge at home, I haven’t used a public charger in almost a year so I was logged out of the app and didn’t want to waste time with password resets (not least because phone 4G reception with O2 in that part of Kingston is horrendous).
And yes I am the registered keeper of the vehicle.
£55 just seems harsh given I did charge for the rest of the afternoon, I had just left the car momentarily to retrieve the physical card from my wife who couldn’t come to meet me

Where are the council's pics? You've blanked the PCN details.

I charged for 4 hours, just got there 3 minutes late hence why I feel a £55 fine is a bit of an over-reach

Why are you continuing with this line here?

You did not start charging until after the PCN was issued. I suggest you make a challenge but remember your points - I won't call them arguments in case you argue, which would be the wrong tone- go to mitigation.

If you don't like London parking penalties..then tango sierra I'm afraid.

Are you the registered keeper with current DVLA details?

or get the wife to park the car.

PM received. But, I need the VRM and PCN details to check their website. How dare they treat musicians like this?!  I will turn the volume up next time I play in the Market Square - when it is free from all the naff stuff on sale there at present.

Cannot access grounds unless you go to add further info.
