New: Technical Guide to Determining the Failure Rates of Automotive Electrical System Components
With increasing electrification and growing requirements for functional safety, the automotive electrical system is becoming an ever-greater focus of attention. This is precisely where the guide “Failure Rates for Automotive Electrical System Components” comes in. Following the first edition in 2021, the second edition was published in June 2026 to provide companies with practical guidance on determining and evaluating failure rates.
The guide was developed in collaboration with the ZVEI as part of the AK ASIL – FIT Rates in the Automotive Electrical System working group, which Bayern Innovativ has been coordinating since 2016 with companies from the automotive value chain—including OEMs, in-vehicle electrical system assemblers, cable manufacturers, connector manufacturers, component manufacturers, machine manufacturers, plant engineers, development service providers, and research institutions.
Comprehensive Expansions to the First Edition
The new edition has been extensively expanded and includes, among other things, additional content on data lines, power connectors, screw connections, and splice connections with larger cross-sections. In addition, field data analyses, laboratory tests, and application and calculation examples have been further elaborated.
As a result, the guide helps evaluate failure rates of passive in-vehicle electrical system components in a more methodologically consistent and traceable manner. The content is based on collaboration among approximately 40 companies.
Further Development Planned
Further development of the guide for a third edition is already planned. Companies and experts are invited to contribute their expertise and practical experience to the next edition.
