This is highly participative session, designed to engage and inspire participants to embrace the content and apply the principles of PAS 7061-2021 and recoup the benefits
What does the PAS cover?This PAS covers batteries for electrically propelled vehicles, including electric vehicles, hybrid electric vehicles, plug-in hybrid electric vehicles and fuel cell hybrid electric vehicles.

7061-2021 Activity Scenario• A company designing and producing battery modules and packs, using supplier sourced
cells had been in production for 3 years.• As part of the initial planning for the facility and monitoring, only production focused
systems were installed within the process to mitigate battery cell thermal runaway events, including fire suppression systems within the production areas and wider building.
• After 3 years of operation, a fire took hold overnight on the production line, spreading to completed battery packs stored in the end of line area. Internal fire suppression systems were triggered and automatically called a national control centre to alert a monitoring company of the incident. No staff were physically in the building and security staff were located at the entry to the industrial estate on which the facility was located. Local residents first alerted the emergency services due to visible smoke.
• As the local fire emergency services arrived, it became apparent they were not aware of the nature of the business.
Group Two: Product safety – Extracts from PAS 7061-2021 6.2.1 The product should be developed and tested in accordance with relevant standards to support the manufacturing, service, re-purposing and re-cycling processes. NOTE Standards that might be useful are BS ISO 6469, BS ISO 12405-4, SAE J2464 and UL 2580. 6.2.2 The battery control unit (BCU) should be developed in accordance with: a) For safety-related systems in electrical, electronic and programmable electronic safety systems, irrespective of where and how they are used, IEC 61508. b) For safety-related systems that include one or more electrical and/or electronic (E/E) systems and that are installed in series production road vehicles, excluding mopeds, ISO 26262 (but including motorcycles in ISO 26262-12). NOTE Developing and testing in this way will support the manufacturing, service re-purposing and re-cycling processes. Attention is also drawn to EC Directive 2001/95 [25] (“the General Product Safety Directive” [GPSD]), UNECE Recommendations on the Transport of Dangerous Goods Part III, Classification Procedures, Tests Methods and Criteria [1], section 38.3 and UNECE Regulation 100 [2]
The competency of staff is critical to the safe management of an environment and therefore any training and education should be based on courses and information used in the automotive industry. • Electricity at Work Regulations 1989 [20]; in particular in the
context of battery systems, Regulations 4, 7, 8, 12, 13, 14 and 16. • HSE has produced guidance to the Electricity at Work Regulations:
HSR25, 2015 and HSE’s publication “Electricity at work – Safe working practices” (HSG85)
• NFPA-70E also provides useful information relating to batteries, e.g. at Table 130.5(C), for arc flash PPE.
8.2.1 The organization should have a documented process to continually manage training for safe work on modules and battery packs.
8.2.2 The process should be structured to take account of the organization’s overall operation within batteries for vehicle propulsion electrification.
NOTE 1 This might be for the manufacture of modules and packs only or for whole life-cycle through to vehicle manufacture, sales, service and ultimate disposal.
