Abstract Increasing demand of Electric and Hybrid vehicles questions more about Reliability and Lifetime of electronic circuits associated with them. It is very important for a hardware circuit designer to evaluate if module will last the expected lifetime. This paper elaborates the methods and steps to find the expected lifetime of critical components; and to decide whether Hybrid Power Electronics Unit (PEU) will meet the OEM requirements on lifetime. Accelerated thermal stress method is used to determine the required High Temperature Operational Life (HTOL) hours for given thermal profile of Hybrid vehicle passenger car in driving (8,000Hrs), charging(30,000Hrs) and total lifetime (38000Hrs ≈ 15Years). Example calculation of required HTOL hours against expected lifetime for critical component from Hybrid ECUs is explained in this paper. Also inclusions and exclusions of this method in evaluating lifetime assessment are also discussed here.

This document covers the process to be applied to Key Characteristics (KC’s) - as defined in AS9103 - on parts, part families or processes as defined by the purchaser or producer. These requirements apply to any product feature, process, or key process input that influences tha ability of the producer to meet or exceed the customer variation management requirements. KC’s include product and process features that benefit from variation management and have a positive impact on Quality, Cost, Delivery and performance of the finished product by the purchaser or their suppliers.. Design characteristics not included within the scope include those on commercially standard parts (for which the customer does not hold design authority) Suppliers who outsource parts with customer key characteristics are responsible for the flow-down of this standard.….

In the development of a motorcycle frame, the balance between high performance and reliability and a short development period are important. In this study, a fatigue durability evaluation technique for a motorcycle frame was developed to enable highly accurate development within a short period of time. Furthermore, we developed a shaking table excitation system as a means to supplement the road test.
