Analog Devices achieves top automotive cybersecurity qualification


management. ISO/SAE 21434 is the new standard for cybersecurity risk management throughout the lifecycle of the vehicle from concept, product development and production, to operation, maintenance, and decommissioning of electrical and electronic systems. TÜV NORD Mobilität, the assessor for this qualification, affirmed that ADI’s wBMS


A


is the first automotive system that it has certified for ISO/SAE 21434. The assessment confirmed that ADI performed appropriate assurance measures within the product development to fulfil the CAL 4 requirements. Since announcing the industry’s first wBMS with General Motors in 2020, ADI has


brought this technology to mass production as a turnkey solution for vehicle manufacturers with security designed in at every level.


The transition of


battery packs from wired to wireless connectivity enables automotive manufacturers to scale their electric vehicle fleets into volume production across a wide range of vehicle classes, and wBMS provides the modularity, flexibility, and scalability to streamline the design and assembly processes with connector-free batteries. With this reliance


on wireless communication, ensuring transparency,


security, and ease of deployment for the system are critical. Roger Keen, general manager of Battery Management Systems at Analog Devices,


said: “Improving the security and accuracy of EV batteries removes roadblocks in end-users’ buying considerations and advances OEMs’ decisions to expand their EV offerings.”

LIA underwrites Knightsbridge with quality accreditation


K


nightsbridge, one of the UK’s leading manufacturers of wiring devices, accessories and lighting, has become a


Lighting Industry Association Quality Assurance (LIAQA) assured company for domestic luminaires, commercial luminaries and emergency luminaires. Similar to the ISO 9001 standard for quality management, the


LIAQA scheme is a lighting-focussed QA mark which assesses a member’s quality systems and its compliance to regulatory requirements. The LIA’s stated mission is to “develop the quality, safety and


performance of the UK Lighting Industry”, and the LIAQA assured company mark means that Knightsbridge has successfully demonstrated that its systems guarantee quality and product compliance with all relevant legislative requirements. Scott Brewer, head of technical at Knightsbridge, said:


“Quality and service is at the heart of everything we do, and we have robust systems in place to ensure compliance with the regulations that underwrite the UKCA product marking scheme. “The LIAQA QA mark gives our customers even greater


grounds for confidence in our products and is testament to the strength and breadth of our lighting ranges.”


Harmonised standards are not sufficient for EMC compliance E


MC Standards has highlighted the relevant harmonised standards are no longer sufficient


for EMC compliance and said businesses probably need to apply IEC 61000-4-16 too. Since the new EMC Directive came into force in


2016, EMC experts likely find themselves having to apply test standards they are not familiar with, and which might not be harmonised by being listed in the Official Journal of the EU (OJEU). Keith Armstrong, global EMC expert at EMC


Standards, said: “If you are still declaring EMC compliance by choosing the most relevant test standards listed under the EMC Directive in the OJEU – then passing those tests and listing them on your Declarations of EMC Conformity — you are five years out of date. This means your products might suffer costly delays in EU and UK customs as a direct result. “Since the EMC Directive 2014/30/EU, and the equivalent UK EMC Regulations, came into force

in 2016, we have been required to perform, and document, an “adequate analysis and assessment of the risks” of our products’ complying with the Directive’s Essential Requirements.” Mr Armstrong explained that the purpose of


these EMC risk assessments is to specify the EMC standards, specifications and guidelines that apply to our products to help ensure their EMC compliance in real life. To help industry better understand these


requirements, EMC Standards has published a free guide on its website. These new assessments are particularly needed


for frequencies below 150 kHz. Mr Armstrong said: “One of the standards that


has been developed to help deal with EMI from DC to 150kHz is IEC 61000-4-16, an immunity test standard that addresses the Common-Mode (CM) noise on cables carrying power, signals, data and even earths/grounds.”
