How to Use your Electric Vehicle as a Power Source During Blackouts

If you asked your parents or grandparents how they imagined the year 2025, many would say we’d have flying cars. While humanity hasn’t quite reached that level of development, we’ve achieved something almost equally impressive, especially for those of us living in Australia where extreme weather events can cause significant disruptions to our power grid.

The creation of electric vehicles has undoubtedly been one of the greatest advances of this century. However, few people know that these vehicles can do much more than simply take you from point A to point B, particularly in Australia where power outages can occur due to various reasons, from weather phenomena like cyclones and bushfires to scheduled maintenance of the electrical grid.

How to Use your Electric Vehicle to Power your Home During Blackouts

Blackouts or power outages not only represent a significant inconvenience but also disrupt your daily life by depriving you of basic communication or climate control devices. These outages often affect multiple communities simultaneously, which demands rapid restoration of services. Imagine waking up in the morning during a scorching Australian summer day and discovering you can’t prepare your coffee due to a blackout. For this reason, having an alternative power source is always a good idea, especially in an emergency. An available electric vehicle can provide backup power, and that source might already be in your garage.

Electric vehicles are an emerging source of reliable backup power thanks to bidirectional charging technology. This technology allows energy to flow from your electric vehicle to the power grid, home, or devices through bidirectional charging. Bidirectional chargers enable some electric vehicles to be equipped with V2L, V2H, or V2G capabilities.

• V2L: Vehicle-to-Load technology allows your vehicle to connect and supply power directly to devices and appliances of your choice.

• V2H: Vehicle-to-Home connects your vehicle directly to your house’s electrical system, distributing power through the connection.

• V2G: Vehicle-to-Grid goes a step further, connecting your car directly to the power grid, distributing it over a larger area and offering a solution for the main power grid during periods of high demand.

In this guide, we’ll focus on V2L technology, as it offers reliability during emergencies. If you’re trying to access your communication devices or simply want to turn on the air conditioning for a few hours on a particularly hot day in Sydney or Brisbane, V2L charging is essential. So keep reading, especially if you have an electric car or are considering buying one.

Bidirectional Charging Technology

Before diving into V2L, let’s take a quick look at what bidirectional charging for electric vehicles is and how it works. As the name suggests, this charging technology allows energy to move in both directions when connected to a power outlet. The bidirectional charger is a fundamental piece in this system, as it allows your vehicle to both send and receive energy, turning it into a power bank for your home. Bidirectional charging requires compatible systems.

Bidirectional charging priorities have made V2L, V2G, and V2H accessible to users. This technology is increasingly available and is provided by various manufacturers. Among these types, V2L is the most accessible form of charging and allows the everyday user to make the most of their investments.

Cars with V2L capabilities come equipped with a built-in inverter and power outlet, allowing users to connect appliances and devices, powering them directly from their car. Unfortunately, not all electric vehicles have this functionality. However, some high-end models do have it, provided by leading manufacturers. Car manufacturers are increasingly offering bidirectional charging features in their electric vehicles.

How Does V2L Work?

But why don’t all electric vehicles work as power banks? Isn’t it just about reversing the current flow? Well, to do that, your vehicle will need:

• Bidirectional inverter: This is necessary to convert the DC energy circulating in the car battery into usable AC electricity.

• V2L-compatible outlets: Outlets are necessary to safely connect devices to your car without damaging them or the car batteries.

• Battery capacity: Sufficient storage space in your car’s battery to be used for extended periods.

Benefits of Using your Electric Vehicle as a Power Source for your Home

Aside from the obvious convenience, the benefits of turning your car into a power source for your home are much more cost-effective and environmentally friendly for keeping your home running during emergencies. Especially considering how long a blackout can sometimes last, here’s what you need to know:

• Reliability: Often, blackouts occur due to natural disasters, such as storms or bushfires, phenomena that are not uncommon in various regions of Australia. The impact is far-reaching. Therefore, having an electric vehicle with V2L as a backup generator can keep all your essential devices running.

• Energy independence: With a V2L-enabled electric vehicle, the quality of your entertainment improves significantly, thanks to effective load management through stored energy. This is more evident during camping trips where you can have power backup wherever you go – perfect for exploring Australia’s vast outback or stunning coastal regions.

• Cost savings: Having your car function as a power backup for your home can reduce the costs of operating a noisy generator and can also help you save quite a bit of money on operating and maintenance costs that come with a fuel generator for the house.

Limitations and Considerations

But even with V2L, there are some limitations and considerations to keep in mind when converting your car into a power bank. Let’s look at some of them:

• Power capacity: Unlike dedicated generators, a V2L cannot power your entire house and has very strict output limits. This means that while you can power essential items like your routers and lights, you can’t run demanding appliances beyond a certain load.

• Risk of battery depletion: One of the most common uses of a V2L is as a backup source in case of emergencies. However, if your electric vehicle’s battery depletes during an emergency, you would be left without essential items and without transportation.

• Australia-specific considerations: Given Australia’s vast distances between population centres, ensuring you have enough charge to both power your home and maintain sufficient range for travel is particularly important.

Setting Up your Electric Vehicle for Home Power

Now that we’ve gone through all the considerations and you’ve decided to connect some of your appliances to your V2L just to check how it works, here’s what you need to do in case of a blackout:

Before starting with the setup, here are some precautions to keep in mind:

• Make sure to check the power limit before connecting your appliances and ensure it’s compatible.

• Keep your garage well-ventilated to prevent batteries from overheating – a crucial consideration during Australia’s hot summers.

• Make sure you have a surge protector installed to protect your car and your appliances.

Step-by-Step Guide

Finally, you’re ready to connect your devices. It’s a very simple process as all you have to do is:

1. Verify battery levels.

2. Locate the V2L adapter or outlet in your car.

3. Connect your devices or extension cords to the outlet.

4. Monitor battery usage to ensure you keep it above certain levels for use in emergencies.

5. Regular software updates ensure compatibility with new electrical appliances.

6. Disconnect appliances before using your car as transportation.

And that’s it! Now, you can finally return to your daily activities without worrying about the blackout.

Real-World Applications

No one wants to imagine themselves in the midst of a natural disaster. However, it’s always better to have something and not need it than to need it and not have it. During tough times, having an electric vehicle with V2L capability can make a significant difference.

In Australia, we’ve seen recent examples of how electric vehicles have become crucial during emergencies. During the 2022 floods in Queensland and New South Wales, some EV owners were able to provide power to essential appliances like refrigerators (to preserve food), phones, and laptops (to stay connected and informed) when traditional power sources failed.

Similarly, during bushfire seasons, when power infrastructure is often damaged or shut down as a precautionary measure, electric vehicles have provided mobile power solutions in evacuation centres and community hubs.

These real-world applications demonstrate how investing in a multi-purpose vehicle can help during unforeseen emergencies. It also offers an effective plan for energy management using the stored energy in your vehicle’s battery.
