Ohme Brand Guidelines: The London Smart-Charging Firm That Began With a Cable

From renewable investment to home charging.

Ohme is a London company that makes smart chargers for electric cars and the software that schedules them. The company gives 2017 as its year of founding and names David Watson as its co-founder; he has been its chief executive in press coverage since its first product launch in 2019. Before Ohme, the company says, Watson co-founded Temporis Capital.

Watson described the starting point in an interview with EV Powered in April 2024. He said he had run Temporis Capital as an investment firm focused on renewable energy, and that as more wind and solar reached the grid he grew concerned about volatile energy prices. Looking at batteries as a way to smooth out the peaks and troughs, he concluded that electric cars, parked most of the time at home or at work, could help balance the grid.

The first product followed from that. Watson told EV Powered that the team’s first step was a smart cable with a 4G chip that could talk to the company’s cloud: plugged into the car and into a home charge point, it would find the cheapest times to charge and send that schedule to the charger. The company says the first working prototype was made in 2018, and that Octopus Energy was the first supplier to take the final production version in 2019, built around Octopus’s Agile overnight tariffs.

The name is short and plain, and the company uses it on its own, without a descriptor, across its products, its app and its website.

Octopus Agile, Home Pro and ePod.

The partnership with Octopus Energy was the launch. Zap-Map reported on 29 March 2019 that Octopus Energy and Ohme had joined forces to offer smart charging with Octopus’s time-of-use tariff: the customer set a requirement, such as a full battery by seven in the morning on weekdays, and Ohme used the supplier’s data to charge when electricity was cheapest. The cable, the report said, could turn any home or public untethered charge point into a smart unit.

A wall-mounted charger came the same year. Auto Express reported on 25 June 2019 that Ohme Technologies Ltd had launched an intelligent home charger controlled through a smartphone app with voice recognition, which worked out how much power the next journey needed and drew most of it at off-peak times, and that shipments to customers who had pre-ordered had begun. The same report said the app let drivers choose to charge only when more of the grid’s electricity came from renewable sources than from carbon-based ones, and that the charger could also be bought through Octopus Energy, with which Ohme had a deal.

The range today is two home chargers. The company’s website lists the Home Pro, a tethered unit with a built-in screen and buttons, and the ePod, an untethered unit controlled by the app and its buttons; both connect through a 4G multi-network SIM card, and the company says both are compatible with solar charging through a feature it calls Solar Boost.

The audience widened from early adopters. Watson told EV Powered that Ohme first served drivers who already understood smart tariffs, then began working with Motability, the scheme that leases cars on behalf of disabled people, and refocused on easier installation, the app and simpler language about cheaper energy. Companies House lists Ohme Operations UK Limited, incorporated in April 2019, with a registered office in London.

Design and documentation.

Makers of electric-vehicle chargers sell a box that most people only notice when they need it. Their pictures therefore tend to put the hardware where it lives: a wallbox on a garage wall beside a parked car, a row of rapid chargers under a canopy at a motorway service area, a cable plugged into a car at dusk with the screen lit. The setting tells the buyer which kind of charging the company means, from overnight at home to a short stop on a long trip.

The second set of images is about the system rather than the plug. App screens show a charging session, a schedule or a fleet of chargers on a map, and diagrams show how power cabinets, posts and software connect. For makers that sell mainly to charging operators, depots and retailers, these pictures often matter more than the car, because the customer is buying a network that has to be installed, monitored and serviced.

Factories are the third theme. Many charger makers show their own production lines, with cabinets moving between stations, technicians testing power electronics and finished units waiting to be shipped, as a way of making engineering visible. Trade fairs play a similar part: events such as Power2Drive in Munich and the international EVS electric-vehicle symposium are where new chargers are unveiled, photographed and compared.

Many of these chargers spend their working lives in someone else’s colours. A rapid charger may carry the livery of the operator, the supermarket or the fuel company whose forecourt it stands on, so a maker’s identity often rests on form: the shape of the cabinet, the placement of screen and cable holders, and a name that may appear only in small type. Reading these brands means looking at the hardware as closely as at the logo.

Car makers, suppliers and new markets.

Much of Ohme’s reach now comes through car makers and their dealers. In September 2026 the company announced that Changan UK had chosen it as its preferred home-charging partner, with Ohme chargers on view in Changan dealerships and Ohme providing installation and dealer training. The same month it announced that it had become the exclusive home-charging partner for Suzuki Australia, adding to its existing partnerships with Suzuki in the UK and Ireland.

The company describes itself in those announcements as a leading UK home EV charging company that is growing quickly in Europe; both are its own claims. Watson remains chief executive and was quoted in the company’s own news in late September 2026.

International growth was the plan he set out in 2024. He told EV Powered that Ohme’s focus for the following twelve months was expansion into Europe and Australia, partly by working with Octopus as the supplier launched tariffs in other countries. The company’s website now runs country sites for the UK, Ireland, Australia, Argentina and much of Western Europe, including Germany, France, Spain, Italy, the Netherlands, Belgium, Austria, Switzerland and Portugal.

The brand vocabulary follows the product: the company speaks of smart charging, energy tariffs, off-peak hours and cheaper, greener times to charge, and its mission statement talks of speeding up the transition to clean energy with affordable, easy-to-use technology.

For a design guide, Ohme shows how a charging brand can be built around time and tariffs rather than hardware alone. Compare Pod Point, another British home-charging brand, and myenergi, the Lincolnshire maker of the zappi. For this guide we use night navy, cool grey and off-peak teal with a geometric sans, an unofficial interpretation; no product or logo is reproduced.
