I would suggest contacting them if unsure as there is no mention of the hub on that website, but parking at a purpose designed hub just for rapid charging and not using the park and ride IMO would not incur a parking fee, but the AC quite possibly.Never used this park & Ride but I suspect you always need a parking ticket even if you only stay for the free first hour.

Petrol can & box o matches?I will be dropping in next week to give the fast charger a go, question is what do I need to take with me if the fast charger issues strike?
