About ev.energy

In 2018, co-founder Nick Woolley’s father wanted to charge his electric vehicle (EV) via solar panels, so he challenged his son to find a solution. Nick was working as a Strategy Manager for National Grid UK at the time, so he knew the significant pressure that EVs could place on the grid. Nick went to California to study how solar and battery storage was being used to feed the US grid and quickly realised EVs are effectively giant, connected batteries that could help balance grid demand and redistribute renewable energy. Integrated correctly, they could actually play a massive role in decarbonising the energy system.

It’s this ambition that underpins Nick and his co-founder Chris Darby’s idea for ev.energy. As 80% of EV charging takes place at home, providing a convenient and compelling experience for drivers to charge at home during grid-friendly times is essential to growing EV adoption sustainably. ev.energy‘s app makes EV charging cheaper, greener and easier – putting drivers in control.

After setting their preferences, drivers can simply plug in each time they get home. The ev.energy app will charge the vehicle by their preferred ready-by time and automatically schedule charging for the greenest and cheapest periods – saving money on drivers’ energy bills. Energy usage, cost and savings can be tracked in the app, and drivers can also integrate home solar generation, access award-winning customer support, and even get cash rewards for smart charging.

To date, over 100,000 users have benefitted from charging with ev.energy. By connecting millions of EVs and controlling the flow of energy, ev.energy has created a Virtual Power Plant where each EV consumes low-cost renewable energy at different off-peak times, freeing up capacity for the grid when demand is at its highest. This increases grid resilience, decreases dependence on fossil fuels, and reduces carbon emissions by up to 30% – all while rewarding drivers and reducing energy bills for all.

To quantify those savings, the average driver covers 10,000 miles a year and most EVs average 3.5 miles driven per kWh. With a variable rate tariff, the ev.energy app could save the driver £657 per year; £626 smart savings plus £30 value in cash rewards. When optimising for home solar – which provides about 40% of the energy needed to charge an EV on average – those savings increase to £734 per year; £376 smart savings, £328 solar savings, plus the £30 in cash rewards.

Since 2019, ev.energy’s B Corp certification has demonstrated its work to deliver broader social and environmental change. In fact, ev.energy has been a carbon-negative business for the past two years – with an estimated saving of 762 tonnes of carbon in 2022. To take its work further, ev.energy is expanding access to its carbon- and cost-cutting tech by working with utilities, vehicle OEMs, charger manufacturers and policymakers to enable a cleaner, more resilient grid through demand response and bi-directional EV charging programmes.
