Australians have been slow to embrace electric vehicles (EVs) compared to drivers in the US, Europe and China. This is due to several factors, including the price of EVs, but also concerns about how practical they are for regular medium- to long-distance drives. This is known as 'range anxiety'.

Range anxiety is simply the fear that the car battery will be empty before you reach your destination or a charging station. In a country where many people like to drive a few hundred kilometres or more in a single trip, and where government support for EVs and charging stations has been slow to appear, this is a natural concern. 

Range anxiety is simply the fear that the car battery will be empty before you reach your destination or a charging station

EV ranges are in fact practical enough for most trips, and there are several charging options available, though it's not all good news. We take you through the options for charging available to an EV driver at home and while out and about, including the types of charger, how long they take to charge the car, typical costs and more.

Types of electric car

There are three types of vehicle that use electric motors. Of these, plug-in hybrid EVs and battery EVs can be charged directly by plugging into a charger, while standard hybrid vehicles charge themselves.

  • Hybrid vehicles have both an internal combustion engine (ICE) (i.e. a petrol or diesel engine) and an electric engine with a very small battery; the battery is charged only by the ICE and by energy captured while braking. It can't be charged directly by plugging the car into a power point. The combination of ICE and electric engines makes hybrid vehicles very fuel-efficient, but still dependent on petrol or diesel fuel.
  • Plug-in hybrid electric vehicles (PHEVs) are similar to regular hybrid vehicles, and the battery is charged in the same way, but it can also be charged directly by plugging the car into a power source. A PHEV battery is larger than in a regular hybrid, but smaller than those in pure battery electric vehicles. PHEVs can do short trips purely on battery power (up to 50km or so, depending on the car), meaning that short commutes and shopping runs can be done as an electric vehicle, with the petrol or diesel engine for backup and for longer journeys. PHEVs offer a lot of flexibility, but like regular hybrids, they come with the service and maintenance costs of an internal combustion engine, and are dependent on petrol or diesel fuel.
  • Battery electric vehicles (BEVs) are purely electric, and therefore need much larger batteries than a PHEV, but don't have any dependency of petrol or diesel fuel, and their electric engines are comparatively simple and inexpensive to maintain.

Driving ranges for electric cars

PHEVs generally have a longer driving range than most purely electric BEVs, thanks to the petrol or diesel engine; and if you're on a very long journey, refuelling a petrol car from empty to full is much faster than charging a BEV. But in electric-only mode, PHEVs have a much shorter range, because of the smaller battery and added weight of the internal combustion engine.

Typical ranges of BEVs

Battery size: The range, or driving distance, for a BEV is largely determined by the size (capacity) of its battery. The battery size is measured in kilowatt-hours (kWh). You may be used to seeing battery power measured in amp-hours (Ah), for instance with power tools, but useable battery capacity also depends on voltage. Kilowatt-hours are a more convenient unit because they factor in voltage as well, and give you one simple number to rate the battery size, much the same way that the size of the tank in a petrol car is a useful indicator of its range (assuming you also know its fuel efficiency).

As for any car, the driving range for a PHEV or EV will usually be reduced by long mountain climbs, carrying more passengers and luggage, headwinds, and driving at high speeds

WLTP driving range: You'll often see the driving range quoted as the "WLTP" range. WLTP stands for World harmonized Light-duty vehicles Test Procedure, and is a standardised set of tests designed to measure a car's fuel efficiency and exhaust emissions in realistic driving situations. It also measures the actual driving range of a BEV.

As for any car, the driving range for a PHEV or EV will usually be reduced by long mountain climbs, carrying more passengers and luggage, headwinds, and driving at high speeds. Very cold and hot temperatures also tend to reduce battery performance. Use the claimed driving ranges as a guide, not a guarantee.

Battery EVs and their ranges

Car model Battery size (kWh) Claimed driving range (km)
Mini Cooper SE Electric 32.6 234
Nissan Leaf (base model) 40 270
MG ZS EV 44.5 263
Tesla Model 3 Standard Range Plus 54 448
Volvo XC40 Recharge  78 418
Tesla Model 3 Long Range AWD 79.5 580

The above specifications are for 2021 models.

As you can see, the battery size isn't the only factor in the driving range; for example, a bigger heavier car may get less range from a given battery size than a smaller lighter car.

What EVs are available in Australia?

The Electric Vehicle Council lists the current EV models on the Australian market on its site.

For a more comprehensive look at the range of pure electric BEVs, PHEVs and hybrid cars on offer in Australia, go to the Government's Green Vehicle Guide and look for the Advanced vehicle search. Search by fuel type and find out the range, annual fuel costs and energy consumption for each model.

How do I charge an EV?

All plug-in EVs in Australia have a lithium-ion battery. The plugs and connectors can differ between makes of vehicle so not all types of charge points can be used with all vehicles. 

There are two things to know about the connection used between an EV and the EV charging station.

  1. How fast will it charge the car?
  2. What type of connection is the plug? 

EV charger levels: Slow, medium and fast

EV chargers are graded into three levels, based on how fast they can charge an EV's battery.

In this section, we use three types of cars as examples for charging times on the different levels of charger:

  • very small battery PHEV: such as a 2021 Mitsubishi Outlander, 13.8kWh battery
  • small to medium battery: such as a 2021 base model Nissan Leaf, 40kWh battery, or MG ZS EV, 44.5kWh battery
  • large battery: such as a 2021 Tesla Model 3 Long Range, 75kWh battery.
electric vehicle charger plug types

EV charger plug types: (L to R) CHAdeMo; CCS2; Type 2.

Types of EV charging plugs

The level of power that the charging point on the wall can deliver is only one part of the EV charging situation; the other is the type of charging port on the charger and the car itself. These plugs and ports have multiple pins; some are for transferring electricity, and others are data connections used by the car and charging station to manage the electricity flow in the best way. Some EVs have multiple connection type options. 

Type 1

This is a five-pin design, not so common in Australia these days. Also known as J1772 or SAE J1772, it's mainly found on older models of the Mitsubishi Outlander PHEV or Nissan Leaf.

Type 2

A seven-pin design, this is the standard type used in Australia and it's what you'll find on pretty much all current BEVs sold in Australia. It's also known as an IEC 62196 or Mennekes plug.

CHAdeMo

Short for "charge de move" ("move using charge" or "charge and go" in French) but also  "(o)cha de mo ikaga desuka" ("do you want some tea?" in Japanese, symbolising that the car can charge in the time it takes you to have a tea break). This is a fast charger connection used by several EV brands, mainly Japanese but including some European brands.

CCS

Another fast charger type of connection, CCS (Combined Charging System) has a set of small pins and two large pins below them. There are two types: CCS1 (compatible with Type 1 connections) and CCS2 (compatible with Type 2 connections). In Australia, many EV brands have a CCS2 port on the car, also known as a CCS Combo, meaning it can plug into either a Type 2 charger or a CCS fast charger. This is good because you can use a Type 2 charger at home, and a CCS fast charger when out and about. Cars featuring this CCS2 Combo port include the Tesla Model 3, Hyundai Ioniq and Porsche Taycan among many others.

Adaptors

There are many adaptors available to allow a car with one plug type to connect to a different type of charging station. There are limits of course; not all combinations are available, and while the right adaptor might allow a car to charge from a level 3 fast charger that would otherwise not be compatible, the car battery will still only charge at its own maximum rate. Adaptor connectors or cables usually cost a few hundred dollars, and can be a useful investment if there are conveniently located but otherwise incompatible chargers you'd like to use.

Charging at home

The easiest way for most people to charge their EV at home is with a level 1 charger; that is, using the charging cable supplied with the car, plugged into a regular power point in the garage. 

Installing a level 2 charger is a better long-term solution (albeit with costs involved) as it will deliver much faster charging, and can get most EVs to a full charge overnight. There are several companies specialising in installing EV chargers in homes. An online search for "home EV charger installation" will bring up several options. We recommend that you contact two or three for quotes.

For most freestanding homes with a garage, or at least with off-street parking, a level 1 or level 2 charger should be an option.

Cost of charging at home

  • This depends on whatever your electricity tariff is at the time of charging. For example, fully charging a Nissan Leaf with a 40kWh battery, on a tariff of 30c/kWh, from 10% charge to full, comes to about $12 (there is usually some power lost in the transfer from charger to battery).
  • If you've got solar panels, then charging your EV during daytime will be very cheap. Of course many EVs will be most often charged at night. 
  • You'll get the best charging efficiency if your parking area is at a moderate temperature. If it is freezing cold or boiling hot, the battery efficiency will reduce and you might not be able to charge it as fully.

But for apartments, homes with no off-street parking, and rented properties, there can be significant challenges to overcome in order to charge an EV at home.

Charging at a public charging station

When you're out on the road, or if you don't have the option of charging the EV at home, you'll need to be familiar with the network of public chargers in your area or on your route. Australia is lagging behind many countries when it comes to rolling out EV charging stations, but there are more available than you might think (especially in major cities and on major highways). It's estimated that we have about 2500 public chargers in Australia; a relatively tiny amount compared to many other countries, but the number is growing.

There are a few types of public chargers. Some are operated by particular companies such as Chargefox or Jolt, and you'll need to have an account with them. This is usually simple to set up, and you'll need to use their smartphone apps when charging your EV at their stations to manage payments and account details. Tesla chargers are often (but not always) for Tesla owners only. 

Motoring organisations are also working on EV charging solutions. The NRMA is rolling out a charger network for its members, RACQ has partnered with government and industry to set up chargers along the Queensland Electric Super Highway (QESH), and RACV partners with Chargefox to give its members discounted access to that network.

Some charger operators and EV brands have set up bundled deals, giving free or discounted access to particular charging networks with the car.

Nevertheless, any EV owner wanting to use chargers owned by different operators (and you almost certainly will need to) may need multiple apps and accounts. It's worth planning ahead before any long trip to make sure you're as ready as possible for your charging stops.

Some charging stations are fairly generic and as long as you have the right plug type (typically a Type 2 charger), you can use the station. Payment is usually by tapping your credit card or smartphone. These stations may be located in shopping centre car parks, council car parks, or roadside charging bays.

There are standard 10A power points to be found in some car parks, where you could plug in your level 1 charger, but check first that the car park owner permits this. 

There are a few websites for locating public charging stations: here are some examples.

Cost of public chargers

Typical fees for using a public charger are:

  • level 2 charger: about 25c per kWh
  • level 3 fast charger: about 40c per kWh.

These fees can vary depending on the operator of the charging station. Other fees may also apply, such as a penalty for leaving your car too long in the charging bay after it has finished charging (to encourage users to free up the bay for other EV drivers).

While EVs are still fairly new and rare, some charging stations are offering free usage. This helps them to attract EV drivers to their location and to gauge the demand for the service.
