Assessing European BESS Regulations to Enable Second-Life Deployment

Overview & Impact:

A renowned leader in electric mobility and energy storage engaged us to examine the regulatory and compliance landscape for BESS deployment across key European markets. Our deep industry expertise and strategic guidance helped the client develop a clear compliance roadmap for deploying new and second-life battery systems in Europe.

Stronger Regulatory Readiness

Clear view of EU battery regulations and safety standards for confident BESS deployment.

Better Second-Life Opportunities

Identified incentives and proven use cases to support repurposed EV battery projects

Client Background:

The client is a global leader in electric mobility and advanced energy storage solutions, driving innovation through cutting-edge technology, sustainable transportation initiatives, and next-generation research.

Challenges:

  • Assessing European BESS regulations across grid, safety, cybersecurity, and repurposed EV battery compliance.
  • Evaluating CE marking and safety certification requirements for both new and repurposed batteries.
  • Analyzing incentive programs and real-world second-life battery project case studies.

Engagement Objective:

The client sought a comprehensive assessment of the regulatory and compliance framework governing BESS deployment across key European markets, along with an evaluation of incentives for new and second-life battery systems and an analysis of real-world repurposed EV battery projects.

Approach:

The team at Stellarix engaged in:

  • Identification of the latest European regulations for batteries, controllers, and BESS systems.
  • Assessment of adjacent regulations (building codes, grid connection, cybersecurity) impacting BESS.
  • Evaluation of repurposed EV battery requirements (SoH validation, re-certification, battery passport).
  • Mapping of fire safety regulations and approval processes for BESS installations.
  • Identification of compliance markings (e.g., CE) and additional testing for reused battery packs.
  • Review of subsidies and incentive schemes for new and second-life BESS projects.

The final outputs include a PPT and an Excel dataset covering regulatory and compliance frameworks, certifications, subsidies, and EV battery reuse cases in Europe, along with expert-validated insights.

Solutions Offered:

Regulatory & Compliance Assessments
Evaluated key EU regulations for batteries, controllers, and BESS, including the EU Battery Regulation (EU 2023/1542), which applies to portable, SLI (starting, lighting & ignition), light means of transport, electric vehicle, industrial, and stationary BESS batteries. The assessment also covered requirements for testing and evaluating second-life batteries, including Battery Passport requirements and State of Health (SoH) validation.
Safety Standards & Certification Assessments
Reviewed certifications and safety standards such as EN IEC 62933-5-2:2020 for overall BESS safety, covering fire, thermal runaway, explosion, electrical risks, and emergency conditions. The assessment considered requirements applicable to both new and repurposed batteries.
Subsidy and Use Cases Assessments
Analyzed subsidy and incentive programs, such as Spain’s Energy Storage Program supporting new non-vehicle battery packs. Also reviewed European second-life BESS deployments, including Connected Energy and Forsee Power’s modular grid-scale storage system using second-life ZEN 35 and ZEN 42 electric bus batteries.

Client Impact:

The client gained clarity regarding EU regulations, safety standards, and second-life battery requirements like the Battery Passport and State of Health validation. Also, Insights into incentive programs and real-world second-life deployments supported informed BESS deployment decisions across European markets.
