It is much cheaper and quicker to charge your vehicle at home compared to a public rapid charger. This is dependent on location, tariff, battery capacity, charging speed and charging level, but charging an Electric Vehicle is far less than petrol or diesel.
Once the battery is charged, the charging stops so go back to sleep, there’s nothing for you to do.
If you subscribe to an octopus energy off peak tariff you can set your batteries to charge at night between 12-5am at a much cheaper rate (currently 12 pence per kwh).
On those cloudy days when the solar is not producing at its best still run your home efficiently and have a 70% saving against the current average daytime energy rate of 45 pence per kwh.
