You’ll find that BEV drivers don’t rely on 7kW AC charging posts as part of their journeying, if they are there at a stop then plugging in for an hour whilst you have lunch is great but not critical to a journey, the only time they matter that much is when all the faster chargers in the area have failed & they risk being stranded.
So, the 7kW AC chargers at the Aldi being blocked is perhaps rude but look back over the years & see how these posts were put in & then simply not used anyway as there were so few EVs around. My local Asda has teh same issue, two out of the 4 charging spaces always blocked by the same PHEVs that are never charging. Don’t rely on them being available.
With a PHEV, always leave home with a full charge, and always plug in at the destination if you can using AC posts or a domestic socket, don’t forget to unplug once charged. It’s the leaving home fully charged that will add up the electric miles the most.
Try to leave a 7kW post at overnight destinations for BEVs that will need to charge for around 7 hours.
