Smart charging for electric vehicles

Smart charging empowers electric vehicle (EV) owners to take control of their energy consumption, reduce costs, and actively support the National Grid. It transforms charging from a simple necessity into a strategic advantage, optimising when and how your EV draws power. This is a power play, shifting the balance of energy control into your hands.

What is smart charging for electric vehicles?

Smart charging is an intelligent approach to powering your electric vehicle. Instead of simply plugging in and drawing electricity immediately, a smart system communicates with your EV, home charger, and the wider energy grid. This allows it to make informed decisions about the best time to charge.

Beyond basic charging

A basic EV charger delivers power as soon as it is plugged in, regardless of electricity prices or grid demand. A smart charger, however, goes further. It considers factors like the availability of renewable energy, current grid demand, and your personal preferences to schedule charging sessions. This means your car could charge when electricity is typically cheaper and greener, without you needing to constantly monitor it.

How smart charging works

Smart charging systems work by integrating several key components: your smart EV charger, your electric vehicle, and often a dedicated energy tariff. The charger communicates with your energy provider's system or a third-party app (like the Fuse app) to access real-time data on electricity prices, grid demand, and renewable energy generation. Based on this information and your set preferences (e.g., when you need your car fully charged), the system automatically adjusts the charging schedule. This allows it to shift EV charging to off-peak hours when electricity is typically cheaper and greener.

The benefits of smart charging for EV owners

Smart charging offers several advantages for EV owners, extending beyond just convenience. It provides a strategic edge in managing household energy.

Reducing your energy bills

By automatically charging your EV during off-peak hours, when electricity rates are lower, smart charging can significantly reduce your running costs. Many energy suppliers offer time-of-use tariffs specifically designed to reward customers for shifting their electricity consumption to these periods. For example, charging your EV overnight when demand is low could be considerably cheaper than during peak daytime hours. This helps you capitalise on periods of abundant, cheaper energy.

Supporting the National Grid

The UK's electricity grid faces fluctuating demand. Smart charging helps balance this by drawing power when the grid has surplus capacity, often from renewable sources. This reduces strain on the infrastructure during peak times, contributing to a more stable and efficient energy system. It aligns with Fuse's mission to build a future with abundant, clean energy.

Environmental advantages

Charging your EV when renewable energy generation is high (e.g., windy nights) means you are powering your vehicle with a lower carbon footprint. Smart charging helps maximise the use of clean energy, supporting the UK's transition away from fossil fuels and contributing to a more sustainable future.

UK regulations and smart charge points

The UK government has implemented regulations to ensure smart charge points contribute positively to the energy system and protect consumers.

Government mandates for smart functionality

New domestic EV charge points installed in the UK are required to have smart functionality. These regulations ensure that chargers can be remotely accessed, controlled, and updated, allowing them to respond to signals from the grid. This mandate supports grid stability and helps manage the increasing demand from EVs.

The importance of smart meters

To fully benefit from smart charging and access time-of-use tariffs, a smart meter is highly recommended, though some off-peak tariffs can be accessed with compatible multi-register meters. These meters accurately record electricity consumption at different times of the day, enabling precise billing based on variable rates. The Radio Teleswitch Service (RTS) for legacy meters is being phased out, with the signal switched off from 30 June 2025. If you have an RTS meter, your current supplier will replace it with a smart meter, usually at no cost. Once you have a smart meter, you can then switch to a supplier like Fuse to take advantage of modern energy management.

Choosing the right smart charger and energy tariff

Making the most of smart charging involves selecting the right equipment and energy plan for your home.

Key features to look for in a smart charger

When choosing a smart charger, consider features such as:

• Connectivity: Ensure it connects to your home Wi-Fi for remote control and updates.
• App integration: A user-friendly app allows you to set schedules, monitor charging, and view energy consumption.
• Compatibility: Check that the charger is compatible with your EV model and your home's electrical system.
• Load balancing: This feature prevents overloading your home's electrical supply by dynamically adjusting charging power.
• Future-proofing: Look for chargers that can integrate with other home energy management systems, such as solar panels or battery storage.

Pairing with time-of-use tariffs

Smart charging truly shines when paired with a time-of-use (ToU) energy tariff. These tariffs offer different electricity prices throughout the day, with lower rates during off-peak periods. By scheduling your EV to charge during these cheaper windows, you could significantly reduce your electricity bills. While Fuse does not offer an active EV-specific tariff from 1 July 2026, general time-of-use tariffs remain a powerful way to maximise savings with smart charging.

Integrating smart charging into your home energy system

Smart charging is not just about your EV; it is a core component of a modern, efficient home energy system.

Maximising savings with solar and battery storage

If you have solar panels, smart charging can be configured to prioritise charging your EV using surplus solar energy generated during the day. This further reduces reliance on grid electricity and maximises the return on your solar investment. Adding home battery storage allows you to store excess solar power or cheap off-peak electricity to use later, including for your EV, creating a more self-sufficient and cost-effective energy ecosystem.

Real-time control with energy apps

Energy apps, like the Fuse app, provide real-time visibility into your energy consumption and pricing. This empowers you to schedule EV charging during the most advantageous periods, track your usage, and understand your savings. This transparent control gives you the capability to manage when and how your EV charges, optimising for cost and grid benefit.

Is smart charging right for you?

Smart charging offers a strategic advantage for UK homeowners with EVs, providing control over energy costs and contributing to a more sustainable grid.

Taking control of your EV charging

The average UK home uses around 2,700 kWh of electricity per year, according to Ofgem. With an EV, this consumption can increase significantly, making smart management crucial. By adopting smart charging, you move from being a passive energy consumer to an active participant in your home's energy strategy. This approach allows you to manage your home energy more effectively without constant manual intervention, turning your EV into an asset for household savings.

The future of home energy

Smart charging is a foundational element of a modern, optimised home energy system. It aligns with a future where energy is abundant and managed intelligently, giving you more power to play with. By embracing smart charging, you are not just saving money; you are contributing to a more stable and efficient grid, aligning with the vision of a future with abundant, clean energy.

Managing your energy bills should be clear and easy to understand. Fuse Energy focuses on straightforward pricing, so you can see exactly what you are paying without unnecessary complexity. If you have a smart meter, you can view detailed usage data through the app or website, helping you understand how you can lower your bills.
