Octopus Energy and Ohme have collaborated to offer smart EV charging to customers, with the energy company’s time-of-use tariff and the new Ohme cable reducing charging costs.

The cable will manage a customer’s charging depending on requirements, and optimising the process to make the most of the Agile Octopus tariff. Customer’s open Octopus’ app, set their requirements – such as ‘On weekdays, charge my car battery to 100% by 7am’ – and Ohme then uses the energy company’s API to automatically draw the right amount of electricity when it is cheapest.

Estimated cost savings could see those using the Ohme cable and Agile Octopus tariff reduced by £300 per year, compared to charging on a typical standard energy tariff. This not only reduces costs for customers on the smart time-of-use tariff, but also reduces load on the grid.

The cable manages to turn any home or public untethered EV charge point effectively into a smart unit, and costs £399. The first 1,000 Octopus Energy customers will get a special launch price of £199.

The cable can feed back a Green Score to drivers, calculating CO2 consumption per mile, and also a cost per mile summary. It can manage an EV driver’s energy usage and sets charging preferences such as daily commutes or regular trips.
