Can I charge my electric car for free at home?
10 December 2020
If you choose the right charge point and electricity tariff, yes....
As Electric Vehicles become more popular the demand on the UK national grid is going to increase. To balance this demand many electricity providers are incentivising EV drivers to charge their cars at off peak times with special EV electricity tariffs.
What are the best electricity tariffs for charging an Electric car
Along with your typical standard energy tariff there are two additional types of tariff designed specifically for EV drivers:
Regular time of use tariffs for charging your EV
These tariffs have lower unit costs at certain times of the day (usually at night) when there is less demand on the national grid. You will know your off peak tariff electricity costs and schedule. This allows you to set a time based charging profile on your chargepoint. Time of use Tariffs are widely available. Economy 7 Tariffs with give you 7 hours of cheaper electricity where as EV specific tariffs usually provide 4-5 hours of cheaper electricity, comparison websites such as rightcharge can help you find the best tariffs in your area
Smart time of use charging for your EV
Innovative agile tariffs have recently been launched by electricity suppliers such as Octopus Energy. These tariffs track the wholesale price of electricity throughout the day, so when wholesale prices drop, so do your bills – and if you can shift your daily electricity use outside of peak times, you can save even more.
Across the UK, whenever more electricity is generated than consumed, energy prices fall – sometimes to the point where prices drop below zero, and suppliers are paid to take energy off the grid. This is when "plunge pricing" happens, which you can benefit from and charge your EV for free. In order to benefit from agile tariffs you will need a smart meter
How do I choose the right smart chargepoint
Intelligent chargers such as Ohme work with all electricity tariffs. However to get the most from your Ohme Intelligent wall charger it’s worth investing a little time exploring your personal EV charging profile before choosing the best electricity tariff for your charging needs.
Intelligent Electric Vehicle Chargers
One of the smartest chargepoints is the Ohme Intelligent charger. It's smart charging works perfectly with agile tariffs, allowing you to benefit from lower cost charging times. It even allows you take advantage of charging your EV during these plunge price moments while being paid to use up excess energy from the grid which can’t be stored.
The Ohme charger comes with the Ohme app which can be downloaded from the app store or google play. The Ohme EV charger can be set up via the app to charge at times when plunge pricing electricity is available, and therefore you could be paid to charge your EV.
Your personal incentive may be cost, greener charging, or a combination of both. Whichever you favour there is a tariff to best suit your needs. Once you have chosen your tariff you can transfer this into the Ohme app, plug in your EV and forget about it safe in the knowledge that when you need it, a fully charged Electric Vehicle awaits.
