About 6 months ago I picked up a used 2020 Kia Niro EV as an extra car, mostly to see if I was ready to go all‑in on an EV for my main driver. I started out with a 240 V, 20 A setup that an electrician installed, and I found out pretty quickly I wasn’t happy with it – it was taking on the order of 18 hours to get a full charge at that rate.
I ended up having the wiring redone and put in a dedicated 240 V, 50 A circuit along with a proper Level 2 wall charger (ChargePoint). The new unit looks cleaner on the wall, makes it easier to manage the cable, and of course charges much faster, so the whole setup is a lot more convenient now.
Early on I also had some issues with the “check EV” warning light coming on intermittently. That led to several trips back and forth to the dealer, but since the car still had a 12‑month warranty they eventually tracked it down to a bad wiring harness and replaced it. It was frustrating, and I suspect the previous owner knew something was up, but at least it’s sorted now.
With the charging upgrade and the harness fixed, the car drives like a dream and has been a really nice introduction to living with an EV.
