Smart EV chargers
Smart EV chargers are an important part of making your home more energy-efficient and sustainable. In this section, we explain what smart ev chargers are, how they work, and what to consider if you're thinking about using them at home. Whether you're just curious or ready to take the next step, you'll find clear, practical answers without the jargon.
What's a smart EV charger and how's it different from a regular one?
A smart EV charger can communicate with the electric grid, your car, and smart meters to optimise charging times and speeds. Unlike regular chargers that just provide power, smart chargers adjust based on electricity demand, price, and renewable energy use. They also require Wi-Fi or mobile data for these features and come with scheduled charging and energy balancing capabilities.
Why should I get a smart EV charger for my home or business?
Getting a smart EV charger for your home or business can save money by taking advantage of cheaper electricity during off-peak hours. It also helps by using more renewable energy when available, and they're convenient by automating the charging process and prolonging battery life. Installing one might cost a bit more upfront, but the long-term savings and benefits often make it worthwhile.
How do smart EV chargers use less energy than regular ones?
Smart EV chargers help save energy by adjusting when they charge your car. They wait for times when electricity is cheaper or more eco-friendly, like at night or when there's extra power from sources like solar. They can also use your home solar panels to charge up, and some even send power back to the grid when it's busy. Regular chargers just power up your car whenever they're connected, using more energy.
Can using a smart EV charger actually lower my electricity bills?
Yes, a smart EV charger can help lower your electricity bills. It does this by charging your electric vehicle during off-peak times when electricity is cheaper. You just need to make sure your energy tariff supports different rates at different times of the day. This way, your car charges when energy is less expensive, cutting down your costs.
How does a smart EV charger work with my home electric system?
A smart electric vehicle (EV) charger is installed into your home's electrical system like an appliance. It connects with your car and the grid through Wi-Fi or mobile networks, managing when charging happens to save on electricity costs and avoid grid strain. It schedules charging for cheaper, off-peak times and uses security features to protect your data.
Are smart chargers good for every electric vehicle?
Smart EV chargers usually work with most electric cars, but not all. It mainly depends on the type of connector your car needs and the charger's power level. Most UK cars use a Type 2 connector for slower charging, but other types like CCS2 or CHAdeMO are for faster charging. If you have a different connector type, you might need an adapter.
What should I look for in a smart EV charger?
When choosing a smart EV charger, look for ones with remote control through an app and the ability to schedule charging during off-peak times, which can save money on energy bills. Fast charging speeds can be handy if you’re often in a rush. Make sure the charger meets UK safety standards and check if it’s eligible for grants to help with costs. Also, ensure it’s compatible with your energy tariff to get the most out of it.
How long does an EV take to charge with a smart charger?
Charging time with a smart charger varies depending on the charger's power and the EV.
