About this project
Network vs Home is a small project that started wanting to understand a simple question, "how does public charging compare to an equivalent session at home?".
Enter details from a single network charging session and you can instantly see how it compares had you completed the equivalent session at home, using the same energy. It compares the cost, time, and cents per kilometre.
A few things you might find interesting:
NZ public DC charging often costs 3–4× the price of home off-peak power per kWh.
Idle fees can add up faster than energy costs on busy chargers — sometimes $1/minute after the session ends.
RUC (Road User Charges) on EVs is $76 per 1,000 km in NZ — about 7.6¢ per km, regardless of where you charge.
The cheapest "fast" option in this app's defaults is Thundergrid at 25¢/kWh — close to home off-peak rates.
A typical 30-minute DC fast charge at 50 kW adds about 25 kWh — roughly 160 km of range in this car.
