Smart charging is an umbrella term that defines all technologies that can control when and how quickly vehicles charge their batteries or discharge their energy back to the private or public network they’re connected to. Vehicle to grid (V2G) charging technology allows participating customers to save or earn money by allowing their EV batteries to store energy and discharge it back to the national grid, or their own buildings, when it’s most needed – for instance at peak demand during the day when usage and costs across the UK are at their highest. This way V2G also increases the positive impact electric vehicles already have in reducing carbon emissions, by supporting the introduction of renewable energy sources to the grid.
