Dejablue has developed a plug-and-play energy management system that increases self-consumption and increases the costs for PV-driven EV charging sites.
Dejable, a company that specializes in smart charging solutions for electric vehicles, announced the launch of a plug-and-play solar optimization module that has been designed to manage EV-plails intelligently on sites equipped with photovoltaic panels.
Dejablue-founded in 2023 by a Franco-American team of technology, energy and mobility experts introduces the first plug-and-play solar optimization module on the French market for EV-chargers on sites with solar energy.
The Dejasense Energy Management System enables companies to increase their self-consumption by 20% to 30%, depending on the number of chargers used, the amount of solar energy produced and their self-consumption speed.
The savings vary with the number of charging stations in operation. With an average electricity price of € 0.17 ($ 0.19)/kWh and a load of 25 kWh, compared to a feed-in rate of € 0.0886/kWh, a French site with 10 charging from 10 vehicles up to € 600 per month can save. The more cars charge, the greater the savings.
Dejablue makes charging smart by taking automatic use according to the company ensures an SME equipped with charging stations, according to the company a return on investment in 3 to 6 months after installation.
Vehicles remain parked for a few hours or days on most EV-Uitueste sites, such as parking spaces for companies and airports or university campuses. Charging does not have to start immediately in this context. Demasense makes it possible to be postponed to coincide with the production peaks of solar production, rather than drawing grid power in the morning. Flexibility maximizes excess solar energy during the day without endangering load levels on departure.
The system adjusts charging sessions dynamically to maximize efficiency and to ensure that each vehicle is charged on time. Easy to implement, the module is installed next to the electrical panel. It is compatible with all open loading point protocollaads and solar stations.
The module measures solar production and consumption in real time and then adjusts charging with an AI algorithm. Managers receive live monitoring, while users can choose between two modes: Eco, which prioritizes solar energy-based load with possible delays or priority for fast charging. In bad weather, the system switches to the grid to guarantee fully charging.
Comepa Industries, a manufacturer of advanced equipment, was one of the first to test the system. With 10 charging terminals on a 140 kVA site in combination with a 120 KW sun factory, the company has reduced the schedule dependence by a third and its self-consumption percentage of the sun raised by 23%.
