EV charging glossary

Every EV charging term you're likely to meet, in one sentence each.

The short answer

The handful of terms that matter most: Type 2 is the plug every new EV in Australia uses; a Mode 2 charger (granny charger) is a portable charger for a power point; kW is charging speed and kWh is battery size; RCM is the mark that shows a charger is legal to sell here.

  • Plug: Type 2 for AC, CCS2 for DC fast charging.
  • Speed: kW. A power point gives about 2.3 kW.
  • Size: kWh. Most EVs have 50–100 kWh.
  • Legal: look for the RCM and an EESS registration.
A to Z

27 terms, explained

AC charging
Charging with alternating current from the grid. The car's onboard charger converts it to DC for the battery. Portable chargers and wall chargers are AC.
DC fast charging
Charging with direct current from a public station that converts power itself, bypassing the onboard charger. Typically 50–350 kW.
Type 2
The AC charging connector (also called Mennekes) used by every EV sold new in Australia today. Seven pins, flat top edge.
Type 1 (J1772)
An older AC connector with five pins and a latch, used by some older EVs such as the 2012–2018 Nissan Leaf and pre-2022 Outlander PHEV.
CCS2
The DC fast-charging connector used by most current EVs in Australia: a Type 2 inlet with two large DC pins below it.
CHAdeMO
An older DC fast-charging standard used by some earlier Japanese EVs, including the Nissan Leaf.
Mode 2
Charging from a standard socket through a portable charger with a control and protection box in the cable.
Mode 3
Charging from a dedicated charger, usually a wall box, permanently wired to its own circuit.
EVSE
Electric vehicle supply equipment: the charger hardware between the outlet and the car. A portable charger is a portable EVSE.
Granny charger
Nickname for a portable Mode 2 charger that plugs into a standard power point.
kW (kilowatt)
A rate of power. A 10 A Australian power point supplies about 2.3 kW.
kWh (kilowatt-hour)
An amount of energy. Battery sizes and electricity bills are in kWh.
Amps (A)
Electric current. Australian power points are 10 A; heavier-duty outlets are 15 A or 20 A.
Dedicated circuit
A circuit that supplies only one outlet or appliance, so the EV doesn't share capacity with the fridge or heater.
RCD
Residual current device, or safety switch. Cuts power when current leaks to earth. Many EV chargers include one.
RCM
Regulatory Compliance Mark. Shows electrical equipment meets Australian requirements and is registered by an Australian responsible supplier.
EESS
The Electrical Equipment Safety System, the national scheme and database that registers electrical equipment and responsible suppliers.
IP66
An ingress protection rating: dust tight and protected against powerful water jets.
IK10
An impact protection rating; IK10 is the highest on the scale.
Onboard charger
The car's built-in AC-to-DC converter. It caps how fast the car can AC charge, typically 7–11 kW.
State of charge (SoC)
How full the battery is, as a percentage.
LFP
Lithium iron phosphate battery chemistry, common in entry-level EVs; often fine to charge to 100% regularly.
NMC
Nickel manganese cobalt battery chemistry, common in long-range EVs; often charged to 80–90% for daily use.
PHEV
Plug-in hybrid electric vehicle: a petrol engine plus a small battery you charge from the grid.
BEV
Battery electric vehicle: fully electric, no petrol engine.
V2L
Vehicle-to-load: using the car's battery to power appliances through an adaptor in the charging inlet.
Off-peak
Hours when electricity is cheaper on a time-of-use plan, usually overnight or, on solar-soak plans, the middle of the day.
