How to benefit from Vehicle-To-Home charging

While there are many benefits to driving an electric vehicle, a lesser-known but very useful one is Vehicle-To-Home Charging, or V2H.

As EVs come with an onboard high-voltage battery, the latest advances in EV technology means that they can be used for far more than just transportation…


What is Vehicle-to-Home charging?

Vehicle-to-Home charging allows you to use your EV’s battery as an energy storage system, working hand-in-hand with a home solar power system to store excess electricity.

This means that your car’s battery can operate as a home battery system, just like the Tesla Powerwall, allowing solar energy from a solar panel system to be captured during daylight hours and used throughout the evening. 

Estimates suggest that our cars are parked up for around 95% of the time, so V2H charging allows EV drivers to capitalise on this by using their cars as an energy storage battery to power their home.

What are the benefits of Vehicle-to-Home charging?

In addition to storing excess energy generated from solar panels, V2H can help you to save money on your energy bills, and reduce reliance on the grid.

You don’t have to own a solar PV system to benefit from V2H. The system also allows you to capture cheaper power when tariffs from the grid are lower, and then release it when tariffs are higher - for example, charging up your EV at night when electricity prices are cheaper, and using that stored energy to power your home at peak hours.

The average UK household could run off the energy stored in an average 60 kWh EV battery for up to five days, making it a great solution for emergencies and power outages, as well as to power your home day-to-day.

Will Vehicle-to-Home charging become more common?

As more and more people make the switch to electric vehicles and solar power, V2H is something that we expect to see becoming far more popular, as a practical way to support your home energy use.

Trials are currently underway in the UK to see how V2H could benefit people who own both an EV and solar panels, and it’s looking positive - the pilot trial by EV charging station manufacturer Indra “has proven that V2H technology can help you save up to £200 a month on your energy bills”, as well as reducing our carbon footprint. 

According to the International Energy Agency, the Net Zero Emissions by 2050 goal would see 300?million electric cars on our roads by 2030, with EVs accounting for 60% of new car sales. That’s 300 million EV batteries available to use for V2H!

Generating and storing our own renewable energy, whether that’s from solar panels or a wind turbine, allows each of us to reduce the use of fossil fuels, lower our carbon footprint, save money on energy bills and reduce our reliance on the grid. 

As the number of electric cars on our roads increase, the role of EV batteries in energy storage will become more important to our day-to-day lives in easing the burden of increased electricity demand from the national grid.
