Super High Efficiency Fast EV charger with energy storage and Grid support functionality: a heart of the future green transport

HEART will develop and commercialize world’s most advanced electric vehicle fast charger based on the cutting-edge silicon-carbide (SiC) technology. With capability to support faster switching frequencies and having improved thermal performance compared to current silicon-based chargers, new SiC-based charger will have much higher power density and higher efficiency, while at the same time at least 15% lower cost per kW compared to today's best fast chargers in the market. Moreover, several innovative smart charging functions (plug and play of supplementary storage, grid support), not available in existing competitor products, will be developed and integrated into the new charger.

Project partners span full value chain; two universities, each highly specialized in the technology they will develop, Danfoss who will commercialize the charger hardware, Hamag who takes the role of original equipment manufacturer and will sell the product, and OK who will field test and buy the product. With several added values, project partners expect that the charger will be the best in class worldwide, thereby enabling tapping into significant EV charging market share. Commercial 2025 target for Danfoss is to sell around 1000 units of the new charger power conversion equipment globally and have at least 40 new permanent employees to support the manufacturing / rollout process, while Hamag expects to secure 20-30% of the national market over a 5 year period following the end of the project.
