How public EV charging works

Public EV chargers are installed at locations like shopping centres, service stations, car parks, rest stops and highway corridors. They are operated by charging networks — companies that install, maintain and manage the chargers and handle billing.

To use a public charger, you typically need the network's app on your phone. You plug in your vehicle, start the session through the app and pay per kilowatt hour (kWh) of electricity delivered. Some chargers also accept contactless card payments, though app-based payment is more common.

Unlike home charging, where you pay your residential electricity rate, public charging prices include the cost of the charging infrastructure, site leases, maintenance and network operations. This makes public charging more expensive per kWh than home charging, but it provides the speed and convenience needed for longer trips and top-ups away from home.

Types of public chargers

Public chargers fall into three broad categories based on their power output and charging speed.

Public AC chargers

AC chargers are the slowest public option, typically delivering 7 kW to 22 kW. They are commonly found at shopping centres, workplaces, hotels and car parks — locations where vehicles are parked for longer periods. AC charging is best suited for topping up over several hours rather than quick stops.

DC fast chargers

DC fast chargers deliver 50 kW to 150 kW and can add significant range in 20 to 40 minutes. They are the most common type of charger along highway routes and at dedicated charging stations. DC fast charging is the practical choice for long distance travel and quick top-ups.

Ultra rapid DC chargers

Ultra rapid chargers operate at 250 kW or more and can charge compatible vehicles significantly faster than standard DC fast chargers. They are typically found at high-traffic highway sites and major charging hubs. Not all vehicles can accept ultra rapid speeds — the actual charging rate is limited by the vehicle's maximum DC acceptance rate.

How public charging pricing works

Most public chargers in Australia price electricity per kilowatt hour (kWh). The price varies by network, charger type and location. DC fast and ultra rapid chargers are more expensive per kWh than AC chargers because of the higher infrastructure cost and the convenience of faster charging.

Some networks offer subscription or membership plans that reduce the per-kWh rate in exchange for a monthly fee. These plans can be worthwhile for drivers who use public charging regularly, but for occasional use the standard pay-as-you-go rate is usually simpler.

A few networks also apply idle fees — an additional charge per minute if your vehicle remains connected after charging is complete. This encourages drivers to move their vehicle promptly so others can use the charger.

Even at public DC fast charging prices, driving an EV is often still cheaper per kilometre than petrol. However, relying exclusively on public fast charging would significantly reduce the cost advantage that home charging provides. Most EV owners use public chargers for long distance travel and top-ups, doing the majority of their charging at home.

Getting started with public charging

If you are new to public charging, getting set up is straightforward.

Download the apps

Install the apps for the major networks before you need them. At a minimum, having the Chargefox and Evie apps covers most of the public fast charging network across Australia. You can add other network apps as needed. The EV Charging Apps page provides quick access to all major apps.

Check your connector

Most modern EVs sold in Australia use the CCS2 (Combined Charging System) connector for DC fast charging. This is compatible with the vast majority of public DC chargers. For AC public charging, the Type 2 connector is standard. Check your vehicle's manual to confirm which connectors it supports.

Plan your route

For longer trips, tools like A Better Route Planner (ABRP) and PlugShare can help you find chargers along your route and estimate charging stops. Most vehicle navigation systems also show nearby chargers, though a dedicated charger-finding app typically has more up-to-date information on availability and pricing.

Know your vehicle's limits

Your vehicle's maximum DC charging speed determines how fast it can actually charge, regardless of the charger's rated power. A 250 kW ultra rapid charger will not charge faster than a vehicle that accepts a maximum of 150 kW. Knowing your vehicle's DC limit helps you choose the most cost-effective charger — there is usually no benefit in paying ultra rapid prices if your vehicle cannot use the extra speed.

Frequently asked questions

Why is public charging more expensive than home charging?

Public charging prices include the cost of installing, maintaining and operating charging infrastructure, as well as site leases, payment systems and network operations. Home charging uses your existing residential electricity supply, so the only cost is the electricity itself. This makes home charging significantly cheaper per kWh in most cases.

Do I need a different app for each charging network?

In most cases, yes. Each network operates its own app for starting sessions and processing payments. Some chargers accept contactless card payments as an alternative, but having the relevant network app installed gives you the most reliable experience and access to membership pricing where available.

Can non-Tesla EVs use Tesla Superchargers in Australia?

Many Tesla Supercharger sites in Australia are now open to non-Tesla vehicles that use CCS2 connectors. Access and pricing for non-Tesla vehicles may differ from Tesla owners and can vary by site. Check the Tesla app or website for current availability at specific locations.

Is public fast charging bad for my EV battery?

Occasional DC fast charging is fine for most modern EVs. Battery management systems control the charging process to protect battery health. However, frequent reliance on fast charging — particularly charging to 100% at high power — can contribute to slightly faster battery degradation over time compared with slower home charging. For most drivers, a mix of home and occasional public fast charging is well within what the battery is designed to handle.
