58 Chapter 5 be robust enough to achieve these life targets. A design life of 15 years may be required to meet the California ZEV requirement, which requires a 10-year warranty and 15-year design life for all emissions-related components. Industrial and grid based applications may require much longer life periods from 15 to 20 years or more in some cases. Design Guidelines and Best Practices Design for Reliability and Design for Service are engineering processes that are critical for ensuring the longevity and life of the energy storage system.
Organizations such as the Automotive Industry Action Group (AIAG) and the American Society for Quality (ASQ) offer both training and templates that can assist an organization in implementing quality programs. The FMEA is an important process that should be conducted in parallel with the core engineering and design processes and should be conducted over a period of time. Lack of history and energy storage systems in the field demand the expertise of the engineering team in evaluating potential failure modes.
