UL and Hyundai team up to make safer second-life lithium-ion ESSs

Wed, 08/18/2021 - 11:21 -- paul Crompton

Battery safety firm Underwriters Laboratory (UL) and vehicle OEM Hyundai Motor Company have signed a deal to help enhance the safe deployment and use of second-life battery energy storage systems (ESS).

The firms will work together on ESS’ using second-life batteries (including safety testing and assessment), a North America demonstration project and an evaluation process development. 

A memorandum of understanding (MoU) was signed on 23 July at a ceremony at UL’s offices in Seoul, South Korea. 

Sajeev Jesudas, executive vice president and chief commercial officer at UL, said: “Reusing batteries in secondary applications is a promising strategy to help combat climate change and carbon emissions.

“We are joining together to consider second-life battery applications as well as their safety and performance potential.”

The batteries from electric vehicles (EV) are deemed ready for second-life use when they “no longer meet the requirements of automotive applications”, but can be used on less demanding grid-connected energy storage applications. 

Anticipating the deployment of second-life automotive batteries for ESSs, UL participated in the development of UL 1974, the Standard for Evaluation for Repurposing Batteries.

The standard, to address the safety and reliability of repurposing batteries, was published in 2018 by UL’s non profit parent, Underwriters Laboratories, as a bi-national Standard of the United States and Canada.

China on verge of banning large-scale ESSs using second-life lithium-ion batteries

China large-scale ESS lithium-ion batteries

Is China on the verge of banning the use of second-life lithium-ion batteries in large-scale energy storage systems (ESS) amid a spate of fires this year?

The halt will continue until a “breakthrough in battery consistency management technology and a sound power battery performance testing and evaluation system” is developed, according to reports from China media group Caixing.

The ceasing of secondary battery use follows the National Energy Administration issued a draft report ‘Regulations for the Management of New Energy Storage Projects’ on June 22.

What capacity constitutes “large-scale” is not clear.

The Caixing report stated: “According to industry sources, there are few energy storage projects that can be called cascade utilization of large-scale power batteries. In addition, the document does not specify the criteria for defining "large-scale" projects.”

The draft also proposes that completed and operating projects should be regularly evaluated and monitored, and supervision should be strengthened.

Cascade utilisation generally refers to using a battery with less than 80% capacity in EESs for commercial and residential, and telecom base station applications.

In January, an explosion at a China recycling plant owned by lithium-ion battery giant Contemporary Amperex Technology (CATL) killed one person and injured 19 more.

In April, two firefighters died when they were putting out a fire in an energy storage power station in Fengtai District of Beijing, according to the China Daily news outlet.
