Mode 2 vs Mode 3 EV charging: what's the difference?

Charging 'modes' come from the international standard for EV charging. You only need to know two of them.

The short answer

Mode 2 is a portable charger: a cable that plugs into an ordinary socket, with a control and protection box built into the cable. Mode 3 is a dedicated charger (a wall box) permanently wired to its own circuit. Both deliver AC power to the car's onboard charger. Mode 4 is DC fast charging at public stations; Mode 1, a plain cable with no protection, isn't used for EVs in Australia.

  • Mode 2 (portable): plugs into a power point or 15 A outlet. For example, the SEVR 10A portable charger.
  • Mode 3 (wall charger): hard-wired by a licensed electrician, usually 7 kW single-phase or 22 kW three-phase.
  • Mode 4 (DC fast): public chargers, 50–350 kW.
  • Same car inlet: Modes 2 and 3 both use the car's Type 2 AC inlet.

Modes are defined in the international standard for conductive EV charging (IEC 61851).
What the box does

Inside a Mode 2 control box

  • Talks to the car over the control pilot signal, telling it how much current it may draw.
  • Checks the earth and supply before switching power on.
  • Protects against faults such as over-current, over-temperature and earth leakage, depending on the model.
  • Switches off if the connection or supply isn't safe.

Questions

Frequently asked

What is a Mode 2 EV charger?

A portable charger that plugs into a standard socket and has a control and protection box built into the cable. It's often called a granny charger or portable EVSE.

What is Mode 3 charging?

Charging from a dedicated EV charger, usually a wall box, that's permanently wired to its own circuit by a licensed electrician.

Is Mode 2 charging safe?

Yes, with an RCM-registered charger plugged straight into a suitable outlet. The in-cable box checks the supply and stops charging if something's wrong.

Is Mode 3 faster than Mode 2?

Usually, because a dedicated circuit can carry more current: 7.4 kW single-phase versus 2.3–3.45 kW for a portable charger on Australian outlets.
