Automotive decommissioned battery energy storage policy document

Can decommissioned power batteries be used in echelon?

When capacity reaches less than 80%, decommissioned power batteries can be used in echelon, that is, in other energy storage fields or equipment with low requirements for battery capacity .

What is detection & evaluation of decommissioned power batteries?

Detection and evaluation are used to judge whether the health state of decommissioned power batteries can meet the requirements of continuous use, including the detection of parameters, such as residual energy, life, and safety.

What is the UL standard for repurposing batteries?

UL. Standard 1974 for Evaluation of Repurposing Batteries. 2018. United Nations Economic Commission for Europe. Manual of Tests and Criteria: Seventh Revised Edition. 2019. Accessed April 20, 2020. U.S. Department of Energy. “U.S. Department of Energy Launches Energy Storage Grand Challenge.” January 8, 2020. Accessed April 20, 2020.

When are batteries disposed as waste?

Where recycling facilities are unavailable or the recovered materials are uneconomic, batteries are disposed as waste.

What is the echelon utilization of waste power batteries?

Attention should be given to matching between basic policy instruments and the industrial chain of echelon utilization. The echelon utilization of waste power batteries has six stages: collection, storage, transportation, detection and evaluation, sorting and disassembly, and echelon utilization.

How are hazard and operability analyses used in automotive rechargeable energy storage systems?

Two approaches, Hazard and Operability Analysis (HAZOP) and System Theoretic Process Analysis (STPA), were used to evaluate hazards associated with automotive rechargeable energy storage systems (RESSs). The analyses began with the construction of an appropriate block diagram of RESS functions and the identification of potential malfunctions.
