Sustainability Practicing -- Vilion's Cascade Battery Energy Storage Application Case

2023-11-24

Our goal of “green energy to flow with demand”can only be achieved if our C&I battery energy storage solutions are environmentally friendly and sustainable enough.

That's true, Vilion kept carrying the leading technology in cascade utilization of the power battery in energy storage.

What is power battery cascade utilization?
· The battery attenuation is gradually slowing down, after long-term use, the battery cannot continue to be used in the EV as it cannot meet the vehicle driving range, but it is still valuable for energy storage; Under the premise of ensuring other performance requirements, there is still available space between "vehicle battery life" and "battery life", therefore, the "retired" battery is screened and recycled, and then re-applied to applications such as peak-load shifting, power backup, capacity expansion and new energy consumption so as to achieve the cascade utilization of batteries.

Why do we promote the cascade utilization of retaired power battery?
Sustainability and safety are paramount in today's business landscape.
· The real retired battery has passed the enough EV mileage test with its safety and reliability been fully verified.
· The total CO2 emissions from the production of the new battery is about 80kg/kWh, while new carbon emissions are minimal when the cascade battery is manufactured. (Source: Carbon Neutral Governor)

When is it time to join in the cascade utilization of retaired power battery?
Don't hesitate to start now!
· In June 2023, the U.S. Department of Energy announced that it would provide more than $192 million (about ￥1.399 billion) to promote the battery recycling technology research and development and create an Advanced Battery R&D Alliance.
· In August 2023, the 'Regulation Concerning Batteries and Waste Batteries (EU) 2023/1542' came into force, and the latest battery regulation will ensure batteries to reduce the carbon footprint in the future and become highly collected, reused and recycled in Europe.
· On January 20, 2023, the Ministry of Industry and Information Technology of the General Administration of Market Supervision issued the Announcement on 'The Implementation of Product Certification for Cascade Utilization of New Energy Vehicle Power Batteries', encouraging qualified enterprises that produce certified cascade products to apply for recognition as "Little giant" enterprises; Encouraging qualified regionals to speed up the construction of resource recycling systems, and use certified cascade utilization products in government investment projects, key projects, and municipal public projects.

How did Vilion do in cascade utilization of the power battery in energy storage?
>20MWh of Vilion’s cascaded BESS are in steady operating and among them, a 3MWh BESS in Indonesia has served safely for 2 years with 0 accident and the latest project in China showed a battery attenuation rate only 0.38% after 7 months+ operating and 428 charging/discharging cycles.
