Best EV Chargers in Australia (2026)

Which EV Charger Should You Install? (Complete Compatibility Guide)

Introduction

Choosing the right EV charger is one of the most common questions for EV owners in Australia.

However, most people make decisions based on charger specifications alone - without understanding how their vehicle, electrical supply, and property setup actually determine charging performance.

This often leads to:

• Overspending on oversized chargers
• Incorrect installations
• Underperforming charging systems

This guide provides a clear, practical framework to help you choose the right EV charger based on real-world Australian conditions.

Quick Answer: What Charger Do You Actually Need?

• If your car is 7kW → install a 7kW charger
• If your car is 11kW + you have 3-phase → install 11kW
• If you only have single phase → install 7kW
• Most homes do NOT need 22kW

🗲 The right charger depends on your vehicle and electrical setup - not the charger size.

The Core Rule (Most Important Concept)

All EVs in Australia use Type 2 connectors for AC charging.

However:

🗲 Charging speed is limited by the vehicle’s onboard AC charger - NOT the wall charger.

This means:

• A 22kW charger does NOT guarantee 22kW charging
• Installing larger chargers without understanding the vehicle often results in wasted spend

What Actually Determines EV Charging Performance

When selecting an EV charger, most people focus on the charger itself - but in reality, charging performance is determined by a combination of factors working together.

There are three key variables that define how fast your EV will charge:

1. Vehicle AC Charging Limit (Onboard Charger)

Every electric vehicle has a built-in onboard charger that controls how much AC power it can accept.

Common limits in Australia:

• 7kW (single-phase vehicles)
• 11kW (three-phase capable vehicles)
• 22kW (rare in Australian market)

🗲 This is the most important limitation.

Even if a charger is capable of delivering 22kW, the vehicle will only draw what it is designed to accept.

Example:
Installing a 22kW charger for a vehicle limited to 7kW will not increase charging speed - it will still charge at 7kW.

2. Property Power Supply (Single vs Three Phase)

The electrical supply available at the property determines what type of charger can be installed.

• Single phase (most homes in Melbourne)
→ Supports up to ~7kW charging

• Three phase (larger homes and commercial sites)
→ Supports 11kW or 22kW charging

🗲 Without three-phase power, higher charging speeds are not possible - regardless of charger type.

3. Electrical Capacity & Infrastructure

Even if your vehicle and power supply support higher charging speeds, the installation must still be designed correctly.

Key factors include:

• Switchboard capacity
• Available electrical load
• Distance from switchboard to charger
• Cable sizing and routing
• Circuit protection (RCBO)

🗲 This is where most installations fail.

A poorly designed electrical setup can:

• Limit charging performance
• Cause nuisance tripping
• Require expensive upgrades later

The Key Principle

The correct EV charger is not the biggest or most expensive option.

🗲 It is the charger that matches:

• Your vehicle
• Your electrical supply
• Your property’s capacity

EV Compatibility Overview (Australia)

How to Use This Guide

The information below outlines the maximum AC charging capability of common EVs in Australia.

However:

• These are maximum values
• Your property setup may limit performance
• Most homes operate at 7kW or 11kW

Tesla

Model 3 / Model Y
• Max AC: 11kW
• Recommended Charger: 11kW

🗲 Ideal for three-phase homes.
🗲 Still works perfectly on 7kW for overnight charging.

BYD

Atto 3 / Dolphin
• Max AC: 7kW
• Recommended Charger: 7kW

Seal
• Max AC: 11kW
• Recommended Charger: 11kW

🗲 Most BYD setups are single-phase.

MG

MG4 / ZS EV
• Max AC: 7kW
• Recommended Charger: 7kW

Hyundai

Kona Electric → 7kW
Ioniq 5 / 6 → 11kW

Kia

EV6 → 11kW
Niro EV → 7kW

Polestar / BMW / Volvo / Audi / VW / Mercedes

Most models:
• Max AC: 11kW
• Recommended Charger: 11kW

Nissan Leaf

• Max AC: 6.6kW
• Recommended Charger: 7kW
• DC: CHAdeMO

What This Means for Most EV Owners

In practical terms:

• Most homes → 7kW charging
• Three-phase homes → 11kW

🗲 22kW is rarely needed.

Charger Selection Logic (Real-World Application)

Selecting the right EV charger should be based on how your vehicle and property interact.

If Your Vehicle is 7kW Limited

🗲 Install a 7kW charger

• No performance loss
• Lower cost
• Simpler install

If Your Vehicle Supports 11kW

🗲 Install 11kW (if 3-phase available)

• Faster charging
• Better future-proofing

If You Only Have Single Phase

🗲 Install 7kW regardless of vehicle

22kW Chargers - Reality Check

• Rarely utilised
• Requires large electrical capacity
• Not needed for most homes

Infrastructure vs Charger (Most Important Distinction)

Most people focus on the charger.

🗲 In reality, the charger is the easiest part.

The real factors are:

• Electrical capacity
• Switchboard design
• Cable routing
• Load management

🗲 A poor setup limits performance regardless of charger.
