How long does it take to charge a MG4 at home?
On a standard 7kW single-phase home charger, a MG4 charges from 20% to 100% in about 7.3 hours, adding roughly 39km of range per hour. The MG4 supports three-phase charging at up to 11kW, which reduces charge time to 4.7 hours (61km/hr). Overnight charging on either setup is more than enough for daily driving.
How much does it cost to charge a MG4 at home?
A full charge (20% to 100%) costs about $17-$19 of electricity depending on your region (NZ residential rates run roughly 33-38c/kWh; overnight EV plans can lower this). On top of electricity, light EVs pay Road User Charges of $76 per 1,000km, so the MG4's full running cost is around $13.1 per 100km. A comparable petrol car costs about $22 per 100km at an estimated $2.60/L, which works out to savings of up to $1,320 a year over 15,000km of driving.
What is the best home charger for a MG4?
The best home chargers for a MG4 are Evnex, Ohme, Wallbox. Since the MG4 supports three-phase AC charging, a three-phase charger (11kW or 22kW) will unlock faster charging speeds. All recommended chargers support smart scheduling, so they can follow the cheap overnight window if you are on an EV power plan.
Do I need three-phase power for a MG4?
The MG4 can take advantage of three-phase power with its 11kW onboard charger, charging about 56% faster than single-phase. However, a 7kW single-phase charger still adds 39km/hr, which is plenty for overnight charging. Three-phase is a nice-to-have, not a must-have.
Does the MG4 pay Road User Charges in New Zealand?
Yes. Like all light battery EVs in New Zealand, the MG4 has paid Road User Charges since 1 April 2024: $76 per 1,000km, bought in 1,000km blocks (an admin fee of about $12.44 applies per online purchase).
