A successful first installation of a 30 kW hybrid storage system for Polytech Nantes.
Hybrid storage is based on supercapacitors (electrostatic) and lithium titanate. Although more expensive to purchase than conventional lithium-ion storage, the total cost of ownership (TCO) is lower and the advantages are numerous:
- A very long lifespan, exceeding 20,000 cycles compared to 6,000 for the best lithium batteries.
- Electrical and physical stability without risk of runaway acceleration
- A discharge depth of 90%
- A simplified loading algorithm
- A wide operating temperature range
This pilot installation is not a laboratory installation, but rather an industrial installation, coupled with 220 kWp of photovoltaic panels and a 25 kW wind turbine.
The combination of “Victron” systems is perfectly suited to managing “SUPRO” batteries and allows for the optimization of renewable energies on site
