Take charge, without a smart meter

You don’t need to have a smart meter to help National Grid ESO protect the energy grid this winter and beyond.

By switching on Smart Charging, you can reduce your impact on the energy grid and earn rewards for your contribution. For those on a multi-rate tariff, we’ll even optimise your charging to get the lowest price.

Watch our video on Smart Charging to learn more.

Why turn on Smart Charging?

Earn rewards

You will earn a £5 reward for every smart charge that you complete (over 7kWh) which you can redeem on the following rewards:

Get the cheapest charge

If you’re on a time-of-use tariff, Smart Charging will always ensure your car is charged at the cheapest possible time according to your rates. ev.energy drivers can save £412 annually on their energy bills through smart charging.

Help to reduce strain on the grid & prevent blackouts:

Every time you smart charge you are helping to reduce energy demand on the grid at peak times. You also reduce your own carbon footprint by charging at times when the carbon intensity of electricity is lower. As a thank you for charging the greener way, we give you rewards in the ev.energy app!

Get started

Go to the ‘Smart’ tab in the ev.energy app, turn on Smart Charging and set your ready-by times. You can always boost on the ‘Dashboard’ tab if you want an instant charge!

Frequently asked questions

How does ev.energy calculate the best times to charge?

Our algorithm has five objectives – in order of priority, they are:

1. Getting your EV charged by your selected “ready by time”
2. Using solar energy from your solar panels when it is the cheapest option
3. Using electricity from the grid at the cheapest times according to your energy tariff (make sure you select the right tariff in the app!)
4. Using electricity from the grid when there is the least demand on the grid, and
5. Using electricity from the grid when the lowest carbon electricity is being generated

When you turn on Smart Charging, you therefore allow us to charge you with the cheapest, greenest energy available.
You’re always in full control of your “ready by” time and can “Boost” charge whenever you need to.
Remember though, Boosting may utilise high-carbon energy at peak prices!

How is Smart Charging better for the environment?

Using your country’s carbon intensity forecasts, we will align the times at which we charge your EV with periods where there is an excess energy supply from renewable sources such as wind and solar. One year of Smart Charging saves 140kg of carbon – the equivalent to the carbon sequestered in seven 10-year-old trees.

And if you have solar panels, our Solar Smart Charging feature allows you to charge your car with your own, free, 100% renewable solar energy, no matter what car or charger you own.

Why do I need to enter my energy tariff/rate?

It’s important you select the correct energy supply to make sure we know when your off-peak periods are. This allows us to save you money by taking your cheapest energy available to you into account (it also means the charging costs/savings we display in the app will be more accurate).

You can let us know your details in the ev.energy app by heading ‘Account’ > ‘Your energy supply’. If you can’t find your supplier or tariff listed, let us know and we’ll get it added to our system! If you don’t select an energy tariff, you won’t see any prices or savings in the app, but you’ll still be able to smart charge (we’ll base your charging on a combination of your ready by time and the carbon intensity of the grid for your region).

Will I actually save any money?

Charging in off-peak hours when the demand for energy is low helps you save money.

If you are on a variable rate energy tariff, enabling Smart Charging allows our platform to schedule your charge during the hours when your energy supplier charges you the least. This is especially useful for tariffs like the Octopus Agile Tariff, which varies every half-hour according to wholesale market prices.

And if you have solar panels, our Solar Smart Charging feature allows you to smart charge with free energy from your own solar panels.

We found that the average EV driver on an Octopus Go tariff who drives 9,400 miles is saving £412 and earning £33 in Rewards per year with the free ev.energy app at today’s prices.

In our Solar Charging Beta, we found that the average EV driver on an Octopus Go tariff who drives 9,400 miles is saving £771 and earning £33 in Rewards per year at today’s prices. Find out how we used real data to calculate the energy savings for our drivers.

I’m on a flat rate tariff, can I still save any money?

You can still save money by claiming one of our smart rewards. You can earn reward points when you smart charge, and then redeem these points on money off vouchers, and more!
