Choice of home EV chargers

Charging your electric vehicle at home instead of public charging stations has several benefits. You do not need to wait in a queue and can get a more personalised charging experience. The two main charger streams for charging an EV at home are portable home EV chargers and dedicated home EV chargers.

Portable home EV chargers (Level 1)

You need to plug these chargers into your regular household socket simply. However, your electrician may still need to inspect the circuit to ensure it is dedicated to EV charging and does not cause overload.

Portable EV chargers can deliver 10A, 15A, and 32A. You may need to upgrade your socket to 15A if it is a 10A unit to use the 15A, 3.6kW models. Meanwhile, the 32A, 22kW model uses 3-phase power and has significantly faster charging times.

Here, electricians may need to install 3-phase socket outlets to go along with 2-phase electricity supplies before you can use the charger. You should note that the maximum charge limit on your car also affects charging times.

Dedicated home EV chargers (Level 2)

Level 2 chargers are dedicated and permanently installed charging units with a dedicated electrical circuit or device. The dedicated device or circuit, such as RCBO and RCD/MCB, helps protect the charging station. You need the services of a licensed electrician to install these chargers.

How to choose home EV chargers

A typical Level 2 EV charger installed for home EV charging can last up to 10 years. As such, you should choose a reliable and efficient EV charger for your home or business to get the maximum benefits.

Here are some factors to consider when choosing this type of charger:

Networked vs. non-networked EV chargers

Networked EV chargers have smart features that allow for more than simple charges at set power rates of non-networked EV chargers. For instance, you monitor the charger wirelessly, and the manufacturer can troubleshoot it remotely.

Pre-installed vs. no pre-installed charging cables

A tethered charger (one with a pre-installed cable) has a cable connector. As such, you do not need to buy a separate one. On the other hand, untethered chargers can charge EVs with different connector types. They do not have fixed, integrated charging cables that allow for good cable length.

Consider the EV charging load management feature

An essential feature of EV charging that you need to consider is the EV charger load management. This is applicable to meet your workplace or apartment EV charging needs optimally.

The loads that Electric vehicles (EVs) bring to bear, the power required to charge them, and the demand for EV charging stations are serious considerations that potential EV drivers make.

Understand your electric vehicle home charging rate

The battery charging rate of your EV can depend on the EV's onboard charger and the rate of the charging station. You must consider this when choosing the right EV charging station.

Your vehicle's charging rate or speed indicates the highest amount of power your charger transfers to your EV battery during the charging process. Regular charging rates in the EV market are 3.6 kW, 7.2 kW, 11kW, 16.5kW or 22kW.

If your EV only has 3.6KW as the maximum charging rate, you cannot use a faster AC charger to boost your charging time even if you plug the car in a 22kW charger.

Keep your EV's charging requirements in mind

EV owners must understand their electric car's charging requirements before buying an EV charger. You may choose a 240-volt Level 2 charger for a faster charging rate than the charging time when using a standard 120-volt outlet.

Choose compatible connector types

Your choice of charger should have a connector that is compatible with your electric vehicle. For instance, you need a Tesla connector for Tesla charger installations. Other connector types include CCS and CHAdeMO.

Choose a charger with intelligent or smart features

Doing this can give you a more convenient and optimal vehicle charging experience. Consider using smart EV chargers with Wi-Fi connectivity, flexible charging session scheduling, and load-balancing features.

Note that EV plug types may either be AC or DC charging. You can choose from the four main EV plug types: Type 1 (J1772 or SAE J1772), Type 2 (IEC 62196 or Mennekes plug), CHAdeMo, and CCS/CCS2.

Choose your EV charger type

There are several levels or types of EV chargers. You must choose the right one, depending on your EV battery.

Supplied Level 1 EV chargers

Your new electric car may come with its own Level 1 EV charger. You can plug it into standard electrical outlets. It supplies a maximum power rate of 2.4kW. Level 1 AC charging has slow charging speeds and low charging power. This option is likely inadequate if you want to charge your EV battery overnight. It is, therefore, less ideal for many drivers.

Level 2 EV chargers – AC fast charging

This is the most popular type of EV charger for home use. It can supply between 3.6kW to 9.6kW using a dedicated AC single-phase connection. Using a three-phase connection, the supply can get up to 22kW. The charging time for Level 2 EV chargers is between 5 to 8 hours for full charges.

Apart from being faster than Level 1 EV chargers, level 2 EV charging stations are more efficient and offer better technological features that increase control over the charging process.

Level 3 EV chargers - DC fast charging

This EV charger type is ideal for those who frequently drive their EVs (over 40km daily). You can conveniently plug your EV into DC fast chargers to recharge your EV quickly. DC fast EV chargers can charge your electric car within minutes, making them the fastest type of EV charger. Remember that certain EVs, like plugin hybrids and PHEVs, may have a lower acceptance rate and be unsuitable for Level 3 charging.

EV charging infrastructure within Australia

There are over 3,000 public charging EV stations. The number of standard EV charging stations is around 1,500. Australia also has over 450 DC fast charging stations. However, these numbers are quickly changing.

This is because public charging has practical limitations. It may be too time-consuming and costly for you. Many EV drivers find it more convenient to use home EV charging solutions. You may compare EV chargers and stations to decide your best option.
