DejaBlue launched DejaSense

DejaSense is a name that expresses the necessary interaction between renewable energy sources and battery packs for the storage and release of the generated energy.

DejaSense: System Details

Produced by DejaBlue, a very young start-up based in Paris, founded just two years ago, DejaSense integrates seamlessly with OCPP-compliant chargers and all solar installations. Installed near the site’s electrical panel, the system continuously measures both solar production and site consumption. A proprietary AI engine coordinates charging across all EV stations, intelligently shifting demand to coincide with solar peaks, typically around midday.

Sites can easily see a 20-30 percent increase in self-consumption and measurable monthly savings. For a typical SME charging 10 vehicles per day, this can represent over €600 in avoided energy costs each month, with the potential savings for large sites measuring thousands of euros per month.

Optimizing the charge rate

The DejaSense kit optimizes the charge rate so that it coincides with peaks in solar energy production, instead of immediately drawing electricity from the public grid right in the morning before the sun fully out. This helps maximize the use of the solar energy produced on the site while still ensuring that all vehicles receive a full charge by the time the vehicle leaves the charging station.

Site managers can manage charging operations, while users can choose between two settings:

●        Eco: Charging will optimize for utilize solar energy while still ensuring the vehicle is charged within the communicated time 

●        Priority: The vehicle will begin charging immediately, irrespective of the solar energy available.

In overcast conditions, the system switches to the public electricity grid to ensure uninterrupted supply.
