Esstalion Technologies Inc. was established in 2014 as a joint venture company between Sony Corporation and Hydro-Québec.(2)
We are the first corporate joint venture between battery manufacturer and utility.
Since then, we’ve developed utility friendly ESS based on lithium ion battery technology for grid scale utilization.
Since we put our importance on safety and long-life, our core technology is olivine based material which is patented by Hydro Québec and commercialise by Sony as Fortelion. (3)
We’ve started in field testing using 1.2 MWh ESS in 2016.
In Esstalion, we try to bring innovation by gathering “multi-wisdom” in ONE ESSTALION team, doing the new material research, BMS/EMS development and ROI calculation etc.
We propose a brief review of our technologies and we will show an example of our efforts to enhance the key properties of the Li-ion battery.
