Demonstration of a hybrid battery storage system
November 2024


We are happy to share that AENEAS partner Flanders Make successfully designed and implemented a hybrid energy storage system in an electric vehicle. By combining energy storage technologies with complementary features, they achieved a significantly extended driving range without sacrificing acceleration performance.
The semi-solid-state battery uses a semi-solid electrolyte, offering higher energy density and improved safety compared to conventional batteries. The kart packs 6 kWh of energy in a compartment the size of a backpack, achieving an impressive energy density of 750 Wh/L or 350 Wh/kg.
The supercapacitor module developed has an energy capacity comparable to that of a smartphone, but can charge and discharge at a massive 24 kilowatts of continuous power. This fast power delivery is ideal for rapid acceleration.
Hybrid energy storage systems like these can play a pivotal role in advancing the electrification of high-demand sectors like construction, agriculture, and maritime.
