Key takeaway
A dedicated home charger charges your car far faster and more safely than a plug socket, and a smart charger charges when it is cheapest.
Why a home charger beats a plug socket
You can charge an electric car from an ordinary three-pin plug, but it is slow and not designed for daily use. A dedicated home charger delivers power far faster and safely, so your car is ready when you are — usually fully charged overnight while you sleep.
What you should know
- Much faster than a normal plug socket
- Designed and certified for daily charging
- A full battery every morning
How a smart charger works
A home charger connects to your electricity supply and to your car with a single cable. Most modern chargers are “smart”, which means they can charge when electricity is cheapest, and some can even top up your car using spare energy from your solar panels — all managed automatically through an app.
What a smart charger adds
- Fast, safe charging
- Charge when it is cheapest
- Charge from your own solar
A typical day with a home charger
When you get home, you simply plug in your car. A smart charger then waits for the cheapest overnight electricity — or uses spare solar energy during the day — and tops the battery up ready for the morning. There is nothing to remember and nothing to switch on; you just unplug and drive.
Frequently asked questions
Can I not just use a normal plug?
You can, but it is very slow and a standard socket is not designed for the demands of daily car charging. A dedicated home charger is far faster and built specifically for the job, which is why it is the safer, more convenient choice.
What is a smart charger?
A smart charger can be scheduled and controlled through an app. It can charge your car when electricity is cheapest and, in many cases, use spare energy from your solar panels — saving you money automatically.
Do I need to do anything each night?
No. You simply plug in when you get home. The charger takes care of the rest, topping up your car overnight or from spare solar during the day, ready for you to unplug and drive.
