BYD & Octopus turbocharge EV revolution at Energy Tech Summit 2025

23-06-2025

●      Britain’s first vehicle-to-grid bundle hits the streets – with FREE EV charging!

●      Bundle includes a leased BYD car, a V2G charger and a smart EV tariff

●      Partnership aims to scale groundbreaking V2G tech and end fuel bills for drivers

London, 23rd June 2025 - Octopus Energy, the UK’s largest energy supplier, has joined forces with BYD, the world’s top electric car maker, to announce the launch of the Power Pack Bundle – the UK’s first vehicle-to-grid (V2G) bundle – and it’s a gamechanger for EV drivers.

Announced today at Octopus Energy’s Energy Tech Summit, the Power Pack Bundle will include a leased V2G-ready BYD Dolphin, a V2G Zaptec Pro charger and access to a smart tariff that offers completely FREE charging at home.

This means typical EV drivers can slash their bills by £620 a year compared to charging on a standard variable tariff – and save almost £1000 compared to fuelling up a gas-guzzler*.

V2G makes EVs work as a battery on wheels - both charging and sending power back to the grid at peak times, reducing the need for having to turn on dirty fossil fuel plants. 

The Power Pack Bundle uses Octopus Energy Group’s tech platform, Kraken, to unlock these savings for customers and make things as simple as possible.

All drivers need to do is plug in their car most nights and let the tech do the rest. The fully automated process leaves drivers with guaranteed free charging at home for all the miles in their lease**.

This is the first time V2G tech has gone commercial in the UK, thanks to the BYD Dolphin’s market-leading technology. With more V2G-ready cars coming soon, hundreds of thousands of EVs could soon act as mini power stations.

Octopus and BYD have also partnered with Motability Operations to make the V2G technology available to disabled people across the UK – ensuring low cost electric driving is accessible to all.

Greg Jackson, Founder of Octopus Energy Group, said: “V2G is the game-changer for drivers and the grid. For the first time ever, drivers can effortlessly power their homes and help the grid – and drive for free in return. V2G is here, available at scale, and ready to revolutionise our entire energy system.”

Stella Li, Executive Vice President of BYD, said: “We’re thrilled to officially launch our V2G project with Octopus Energy and Kraken.

“BYD is fully committed to making intelligent, innovative, sustainable technologies available to our customers, and this project will allow them to unlock the full potential of electric vehicles - not just as transport but as dynamic assets that can play a key role in supporting the grid.

“Together with Octopus Energy, we’re enabling EV owners to play an active role in the energy ecosystem, reducing costs and increasing the resilience of renewable power systems.”

Andrew Miller, Chief Executive of Motability Operations, said: “It’s great to see V2G technology becoming available at scale – effectively turning EVs into energy assets that can help power homes and support the grid. For our customers, this could mean significantly lower energy bills and an even more affordable route into electric driving.”

“We’re proud to be part of a pilot that’s not only breaking new ground in energy, but also ensuring the benefits are accessible to disabled people across the UK.”

The Power Pack Bundle will be available later this year. Interested customers can be the first to get their hands on the tech by placing a reservation on the list with Octopus EV.

What is V2G?

It’s a car + charger upgrade that allows you to both charge up your car from the grid, as well as export energy from your car battery back into it.  The Octopus Energy in-house technology platform, Kraken, “talks” to the car and automatically fills it up when energy is at its greenest and then exports back to the grid when it needs help (e.g. when there is a big spike in demand, like when everyone arrives home in the evenings).

What is exciting about the V2G developments in the Dolphin?

There are two primary methods of V2G, through: In-Vehicle Inverters or Off-Board Inverters (which means the tech is either; located within the car, or within the charging station itself). The BYD Dolphin V2G inverter is built into the car. This means the car handles the electricity conversion required between AC-DC and the charger is relatively passive - it just acts as a communication interface and safety gateway. This means: - The charger is ‘standard’ and can work with all EVs (but only the Dolphin can do V2G) - The charger is smaller, less visually obtrusive and easier to install

Where can I get a V2G Dolphin?

The V2G Dolphins are available via Octopus Electric Vehicles as part of the Power Pack Bundle. This includes a V2G Dolphin lease, a V2G-ready charger at one monthly price, unlocking access to the Power Pack tariff from Octopus Energy. You can find out more about the bundle and the tariff here

Where can I test drive a V2G Dolphin?

The V2G Dolphin won’t be any different from non-V2G Dolphins in terms of driving experience. Grab a test drive at your local BYD dealer to get a feel for the car.

What is included with the V2G Dolphin?

The Power Pack Bundle includes a V2G Dolphin lease, a V2G-ready Zaptec Pro charger at one monthly price, unlocking access to the Power Pack tariff from Octopus Energy. You can find out more about the bundle and the tariff here

What else will be available in the future?

The Dolphin is the first foray into Vehicle-to-Grid for BYD. In future V2G capabilities and other smart charging features will be available on a wider range of BYD models.

I already own a Dolphin, can I get V2G?

At the moment V2G is only available on a select group of new Dolphins cars.
