EV ⮕ Electric Vehicle
- EV ⮕ “battery electric vehicle”. Synonymous with EV, but specific to all-electric cars with a battery. No hybrids, no petrol, no hydrogen.
- PHEV ⮕ “plug-in hybrid electric vehicle”. As the name suggests, these cars accept combustion fuel and an electric plug. Not the same as regular hybrids, which only take fuel.
- (kW) ⮕ “Kilowatt” measurement of electrical power (how fast a car is charging).
- (kWh) ⮕ “Kilowatt Hour” measurement of energy (how full a car battery is); equal to one kilowatt of power delivered for one hour.
- EVSE ⮕ “electric vehicle supply equipment”. Term for all kinds of charging equipment: stations, cables, leads, adapters, etc.
Types of Charging
- Trickle Charging ⮕ a slow charge, usually overnight, when the battery is close to full or the charger can only supply a small amount of power.
- Fast Charging ⮕ typical charging from home or public charging stations.
- Rapid Charging ⮕ public stations that use DC power to charge your vehicle extremely quickly. Generally upwards of 50 kW.
- Mobile Charging ⮕ charging from a domestic power outlet using a portable charging cable.
- AC Charger ⮕ a charger that outputs alternating current (AC) power. Used in home chargers or smaller public stations where drivers are likely to park for longer.
- DC Charger ⮕ a charger that outputs direct current which flows directly into the battery. This is more efficient than AC charging; often found on highways or locations where speed is a priority.
- RFID ⮕ a radio frequency card-based ID technology used to access public charging stations.
- Type 1 ⮕ the first plug-type to appear in New Zealand; these have been replaced by Type 2 as the standard for New Zealand EVs. Use an adapter to access public chargers with these plugs.
- Type 2 ⮕ the New Zealand standard EV plug design, used by charging networks nationwide. Older EVs with Type 1 plugs will need an adapter to use these.
- CCS ⮕ “Combined Charging System”. A plug design that allows regular AC charging and fast DC charging with the same plug.
- CHAdeMO ⮕ abbreviation of the French “CHArge de MOve”; a DC-specific fast charging plug used primarily by Japanese manufacturers.
- GPO ⮕ “general purpose outlet”. An abbreviation for the standard 3-prong power plugs used throughout New Zealand.
EV charging is divided into three easy-to-understand levels.
Level 1 ⮕ charging from a GPO using a portable charging cable.
Level 2 ⮕ charging from an AC charging station at home or in public. This method uses EV-specific plugs and stations and is usually at least 3x faster than level 1 charging.
Level 3 ⮕ charging from a DC charger. Stations of this size and speed are generally only available on select public networks or for commercial use. DC charging is incredibly powerful, delivering full charges in as little as 15 minutes.
Single Phase Power ⮕ The most common type of power, used in most residential households.
Three Phase Power ⮕ More common in industrial areas but can also be found in some residential areas. It is capable of transferring more power to certain compatible EVs.
