Level 1 vs Level 2 — Which Do You Need?
Level 1 (standard 10A/2.4kW wall socket): - Free to use — already in your garage - Charges ~15km of range per hour - Suitable for low-mileage drivers or plug-in hybrids - Not recommended for full EVs driven daily
Level 2 (7kW dedicated circuit): - Charges ~50km of range per hour - Full EV (60–80kWh battery) charged overnight - Requires a dedicated 32A circuit installed by a licensed electrician - Recommended for most EV owners — peace of mind, full charge every morning
Three-phase (22kW): - Charges ~150km per hour - Primarily useful for commercial/fleet or drivers with very high mileage - Requires three-phase power supply (many NZ homes are single-phase only)
Smart Chargers
Smart / Wi-Fi chargers allow: - Off-peak scheduling — charge overnight when electricity is cheapest - Load balancing — reduce charge rate if household power demand is high - App monitoring — track kWh charged and cost - Solar integration — some models can prioritise charging from solar generation
Popular brands in NZ: Wallbox, EVNEX, Schneider Electric EVlink, Ohme.
