Fuuse provides the link between EVs, buildings and electricity grids

When it comes to electric vehicles (EVs), the electricity to charge them is often part of the power supply for a building. No matter how smart the vehicle itself is, or the charging infrastructure for that matter, additional monitoring or metering, and sometimes remote switching is required to integrate the EV charging with energy and carbon management for the whole site. That’s where Wattwatchers comes in!


When Wattwatchers’ first UK-based software partner Envisij was acquired in 2022 by fast-scaling Fuuse, a flexible chargepoint management software (CPMS) for electric vehicles (EVs), our energy IoT devices went along for the ride. 

Recently, Envisij has been rebranded by Fuuse, with Wattwatchers inside the suite of tools to help its customers to manage, monitor and monetise on-site energy, enabling them to transition to EVs efficiently.  

The business understood from early on that EV charging needed to operate in the context of whole-of-site electricity use. Especially for the relationship between commercial and industrial sites and the grid, such as supply capacity and restrictions, and demand limits and charges. 

Converging transitions 

Fuuse, founded in 2021, put this interrelationship between the EVs, the sites and the grid at the data-enabled heart of its solutions for the convergence of two transitions

The first of these is internal combustion engine (ICE) vehicles to electric-powered ones, and the second is fossil-fuel energy to renewables. 

EVs can be very smart, and so can EV chargers, but without further intervention they can be operating in isolation from their host sites, effectively blind to the bigger picture for electricity supply and demand management. 

That’s where Wattwatchers’ monitoring and control solutions come into play, integrating with the Fuuse EMS, and subsequently with their CPMS – which describes itself as ‘the flexible back office for EV chargers’. 

Maximise value 

The ultimate aim is to maximise the value of EV charging for host sites, with Fuuse EMS providing the toolkit – including Wattwatchers inside – to monitor, manage and monetise EV charging infrastructure at customer sites. 

The business rationale for Fuuse EMS has a straightforward context for operations at customer sites, which is explained thus: ‘Understanding the relationship between your site energy and your EV charging infrastructure is essential for smooth operations. Fuuse EMS offers a suite of tools to enable data-backed decisions through comprehensive energy usage data, maximise fuel savings with Multi Level Dynamic Load Balancing, and generate revenue responding to grid demand.’ 

In October 2022, ahead of the launch of the Fuuse EMS toolkit, Fuuse became the first software provider in the UK, working exclusively with aggregator Flexitricity, to announce participation in the National Grid’s Demand Flexibility Service for commercial EV charging infrastructure. 

Envisij founder Gary Highton, now Head of Energy Services at Fuuse, told the Electricity Times that: As a business with the innovative solutions and tools in place to facilitate demand response needed for the new Demand Flexibility Service, it is our responsibility to get as many organisations on board as possible.’ 

About Fuuse: Launched in 2021, Fuuse is the flexible back office system for EV chargers, powering hardware to cater for the evolving needs of organisations and their EV drivers. Through its intuitive features, Fuuse helps both private and public sectors to get what they need from their EV charging infrastructure, breaking down barriers to EV transition. Every part of the Fuuse business is committed to helping reduce CO2 emissions in transport. Fuuse EMS links EVs, buildings and the energy grid. With increasingly limited electrical capacity, there is a greater need to optimise how energy is used. Fuuse EMS is a suite of tools to help users to manage, monitor and monetise site energy, enabling them to transition to EVs efficiently.
