There are three relevant modes of EV chargers ranging from Mode 2 to Mode 4 (Mode 1 is not deemed a safe charging method in New Zealand).

  • Mode 2 (AC trickle charging):  This is the most basic home or destination charging option, where you plug the car into a standard 230V AC (alternating current) socket using specialised charging equipment (usually supplied free with EVs). This is the slowest method of charging, taking up to 48 hours to charge your car. In our view, they are best used as travel chargers or emergency back up chargers, rather than a main charger.
  • Mode 3 (AC fast charging):  When most people talk about ‘dedicated EV chargers’, this is the type of charger they’re usually referring to (and the type we normally install). These are the chargers that are typically installed in residential homes, in strata and commercial building car parks and at some businesses. A full charge takes between six and twelve hours (depending on your vehicle’s battery size). This makes it viable to charge your EV overnight at home or throughout a workday.

Mode 4 (DC rapid charging): Mode 4 chargers are the rapid chargers used at service stations, street side charging, for fleet vehicles and for certain commercial users. Mode 4 chargers will usually charge your battery to 80% within half an hour – perfect for long distance travel. However, these stations sometimes require more power than your entire house, cost upwards of $25,000, and require major panel and service upgrades – which is why they’re not feasible for home use.
