Smart charging: how to get cheaper EV power

Smart charging optimises when your electric vehicle (EV) charges, aligning it with periods of lower electricity demand or cheaper tariffs. This intelligent approach allows EV owners to significantly reduce their charging costs by utilising off-peak electricity rates, moving beyond simple plug-and-charge habits. It also plays a vital role in balancing the national energy grid, contributing to its stability and efficiency.

Smart charging your EV can lead to significant savings on your energy bills, especially when paired with a dual-rate tariff. Fuse Energy offers competitive tariffs designed to complement smart charging, helping you take control of your electricity costs. Click here to switch to Fuse Energy today.

What is smart charging for electric vehicles?

Understanding the basics of Intelligent EV charging

Intelligent EV charging, commonly known as smart charging, is a system that manages the charging of electric vehicles by optimising the charging schedule. Instead of charging immediately upon plugging in, a smart charger can communicate with the grid, your energy supplier, or a dedicated app to determine the best time to power up your vehicle. This typically means charging when electricity is cheaper and demand on the grid is lower. It is a fundamental shift from reactive charging to a proactive, cost-effective, and grid-friendly approach.

Key benefits for EV owners

For EV owners in the UK, smart charging offers several compelling benefits. Primarily, it leads to substantial cost savings on electricity bills by enabling charging during off-peak hours when tariffs are lower. Beyond financial advantages, smart charging enhances convenience by automating the charging process, allowing you to set preferences and let the system handle the rest. It also contributes to a more sustainable energy system by reducing strain on the grid during peak demand, helping to integrate more renewable energy sources.

How smart charging saves you money

Leveraging dual-rate energy tariffs

The most direct way smart charging saves you money is by leveraging dual-rate energy tariffs. These tariffs offer different electricity prices depending on the time of day, with significantly lower rates during off-peak periods, often overnight. By scheduling your EV to charge exclusively during these cheaper windows, you can drastically cut the cost of running your electric car. For instance, the average UK home uses around 2,500 kWh of electricity per year, according to Ofgem's Typical Domestic Consumption Values (TDCVs) effective from 1 July 2026. If a significant portion of your EV charging, which can add thousands of kWh to your annual consumption, occurs during off-peak times, the savings quickly add up.

Optimising for off-peak electricity prices

Optimising for off-peak electricity prices means more than just charging overnight; it involves understanding your energy tariff and setting your smart charger to operate when rates are at their lowest. For context, the Ofgem Price Cap default tariff for 1 July to 30 September 2026 sets electricity at 26.11p per kWh, inclusive of 5% VAT. During off-peak hours on a dual-rate tariff, this price can drop considerably, making smart charging an attractive option for cost-conscious EV owners. Energy suppliers like Fuse offer dual-rate tariffs specifically designed to complement smart charging, enabling significant cost reductions for those who charge during these advantageous periods.

Smart charging and the UK energy grid

Contributing to grid stability and efficiency

Smart charging plays a crucial role in maintaining the stability and efficiency of the UK's energy grid. By shifting large loads like EV charging away from peak demand times, it helps to prevent grid overload and reduces the need for expensive, carbon-intensive backup power generation. This distributed management of energy demand is essential as the number of EVs on the road continues to grow. It aligns with a vision of energy abundance, allowing EV owners to consume more energy when it is cheapest and most plentiful.

The role of demand-side response

Demand-side response (DSR) is a mechanism where electricity consumers are incentivised to adjust their energy usage in response to signals from the grid. Smart charging is a prime example of DSR in action. When the grid experiences high demand or low renewable generation, smart chargers can pause or slow down charging. Conversely, when there is an abundance of renewable energy (e.g., windy nights), charging can be ramped up. This flexibility helps balance supply and demand, making the grid more resilient and efficient, and contributing to a more stable national energy infrastructure.

UK regulations and smart charger requirements

The smart charge Point regulations explained

The UK's Smart Charge Point Regulations 2021 mandate specific functionalities for new home and workplace EV charge points installed in Great Britain. These regulations require charge points to have smart charging capabilities, enabling them to be remotely accessed, controlled, and to send and receive information. This ensures that new installations can contribute to grid balancing and that consumers have the tools to manage their charging effectively. These regulations are a key part of the UK's strategy to manage the transition to electric vehicles.

Choosing a compatible smart EV charger

When choosing a smart EV charger, compatibility with smart energy management systems and adherence to UK regulations are paramount. Many modern chargers, such as the Easee One EV charger, are designed with these requirements in mind. The Easee One, for example, has a 32A current rating and 7.4 kW power output, making it suitable for home charging while also being compatible with smart functionalities. It is important to ensure your chosen charger can connect to your energy supplier's app or a third-party smart charging platform to fully utilise dual-rate tariffs and optimise your charging schedule.

Getting started with smart EV charging

Connecting your charger to a smart energy app

Once you have a compatible smart EV charger, the next step is connecting it to a smart energy app. Many energy suppliers, including Fuse, offer dedicated apps that allow you to manage your charging schedules. These apps empower you with transparent control over your energy usage and costs. You can typically set your desired charge level, departure time, and let the app automatically charge your EV during the cheapest off-peak hours.

Monitoring and maximising your savings

To continuously optimise your smart charging strategy, it is crucial to monitor your energy usage and the savings you are making. Smart energy apps often provide detailed insights into your charging patterns, costs, and the environmental impact of your choices. By regularly reviewing this data, you can fine-tune your charging schedules, ensuring you are always taking advantage of the lowest electricity prices and maximising your financial benefits. This proactive approach ensures you are getting the most out of your smart charging setup.
