Electricity isn't just expensive

[harm_less]

I read somewhere meridian? are going to start charging 50c kwh at their charging stations, does that seem reasonable given domestic charges are around 30c kwh?

Cheap compared to Chargenet's facilities, but in most cases slower. Someone has to pay for all that investment in infrastructure, IT and admin. Around 90% of EV owners in NZ charge at home at offpeak rates or from solar so public charging isn't as important for most except when we go on a road trip. At 50c/kWh it still equates to ~10c/km so still way cheaper than putting petrol in your car.
