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

If you were to ask your parents or grandparents how they imagined the year 2025, many would have said we would have flying cars. Whilst humanity has not reached that level of development, we have accomplished something nearly as impressive.

The creation of electric vehicles has undoubtedly been one of the greatest advancements of this century. However, few people realise that these vehicles can do much more than simply transport you from point A to point B, especially in regions where power outages can occur due to various reasons, from weather phenomena to electrical grid maintenance.

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

Power outages or blackouts not only represent a significant inconvenience but also disrupt your daily life by depriving you of basic communication or climate control devices. These affect multiple communities simultaneously, necessitating rapid restoration of services. Imagine waking up in the morning to discover you cannot prepare your coffee due to a power outage. 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 reliable backup power source thanks to the use of bidirectional charging. 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 Vehicle-to-Load (V2L), Vehicle-to-Home (V2H), or Vehicle-to-Grid (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 takes it a step further, connecting your car directly to the electrical 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 will focus on V2L technology, as it offers reliability during emergencies. If you are trying to access your communication devices or simply want to turn on the air conditioning for a few hours during a particularly hot day in Singapore, V2L charging is essential. So keep reading, especially if you own an electric car or are considering purchasing one.

Bidirectional Charging Technology

Before delving into V2L, let us 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 enables 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 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.

• Hyundai Ioniq 5: a mid-range SUV that boasts impressive V2L capabilities, allowing it to power devices with a maximum charge of 3.6kW, making it one of the pioneers in V2L technology.

• Kia EV9: the EV9 takes a more elegant approach, providing a high-performance electric vehicle equipped with rear and interior outlets, making it a perfect companion for road trips.

• Tesla Cybertruck: when the Cybertruck was released, there was nothing like it on the market, and if you look at its V2L capabilities, there still isn’t, as it comes with a 9.6kW output.

• Chevrolet Silverado EV: the Silverado is not your typical cargo carrier, as it comes complete with a PowerBase charger, designed to maximise utility. This allows it to have 10 outlets capable of providing 7.2kW of V2L power. The Silverado’s charging port supports external devices, enhancing its utility.

• Cadillac Lyriq: built for people who enjoy the finer things in life, this luxury SUV has both V2L and V2H capabilities.

How V2L works

But why don’t all electric vehicles function 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 flowing in the car’s battery into usable AC electricity.

• V2L-compatible outlets: outlets are necessary to safely connect devices to your car without damaging them or the car’s 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

Setting aside 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 power outage can sometimes last, here is what you need to know:

• Reliability: often, power outages occur due to natural disasters, such as storms or earthquakes, phenomena that are not uncommon in various regions globally. The impact is far-reaching. That is why 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 charge management through stored energy. This is most evident during camping trips where you can have power backup wherever you go.

• Cost savings: having your car function as 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 operation 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 you should keep in mind when turning your car into a power bank. Let us 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 whilst you can power essential items like your routers and lights, you cannot 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.

Setting Up your Electric Vehicle for Home Power

Now that we have gone through all the considerations and you have decided to connect some of your appliances to your V2L just to check how it works, this is what you should do in case of a power outage:

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

• Be sure to verify the power limit before connecting your appliances and ensure it is compatible.

• Keep your garage well-ventilated to prevent batteries from overheating.

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

Step-by-step guide

Finally, you are ready to connect your devices. It is a very straightforward 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 to use in case of emergencies.

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

6. Disconnect appliances before using your car for transportation.

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

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 these difficult times, Kat Hickey, a resident of northern Brisbane, utilised her V2L-enabled electric vehicle to provide her home with essentials such as phone and laptop chargers, and refrigerator, essentially turning her house into a smart home.

Similarly, Matt McLaughlin from Gold Coast Hinterland used his family’s 3 electric vehicles as home power solutions during the cyclone. This demonstrates how much investing wisely in a multipurpose car can help you during unforeseen emergencies. It also offers an effective plan for energy management using the stored energy in your vehicle’s battery.

These experiences from abroad could be equally valuable in the Asian context, where phenomena such as typhoons, tropical storms, or even earthquakes can cause prolonged power outages in both urban and rural areas. In Singapore, whilst major power outages are rare, the increasingly unpredictable weather patterns due to climate change make preparation all the more prudent.
