I had a 3KW dumb Polar charger fitted back in 2015 for a Mitsubishi PHEV (13kw battery) which would charge in 3.5 hours. I suppose I could have managed with a 3 pin plug, but getting the cable out of the boot and plugging into a three-pin in doors would have been a PITA (I’ve been doing that at work recently and for a wheelchair user its problematic to say the least). The convenience of a wall charger (if you have off-road parking) is great but with no grants anymore it doesn’t make financial sense (unless you want my old 3kw dumb charger that I’ve deinstalled).
Good point. I’m fortunate that I can charge our PHEV inside our garage (where I always park the car), so I can see that a charger would be easier for those who can’t do that even though, as you say, it’s more about convenience than making financial sense. The charging cables are a bit of a faff and I’m able bodied!
