Octopus Energy customers with an electric vehicle will be able to charge at low price periods using a ‘smart’ cable from Ohme.
Once the cable is connected, the driver uses an app to set charging instructions (eg “On weekdays, charge my car battery to 100% by 7am). Ohme then uses the Octopus Agile interface to charge when the power is cheapest.
The cable can be used with any electric vehicle and any existing charge socket, including public charge points. It manages EV drivers’ energy usage and sets charging preferences like daily commutes and weekend trips, and receives a summary of drivers’ cost per mile.
Octopus Energy and Ohme estimate that customers using Ohme with the Agile Octopus tariff could save around £300 per year, compared with a standard variable tariff.
The cable will cost £399, but the first 1,000 Octopus Energy customers will pay £199.
