  text: For modern machines, factories and electric and autonomous vehicles, the importance
    of vreliable electrical connectors cannot be overstated. With an increasing number
    of connectors being used in machines, factories and vehicles, ensuring their reliability
    is crucial for comfort and safety alike. One of the key indicators of reliability
    is the lifetime of connectors. To evaluate the lifetime of electrical connectors,
    a testing method and a model for calculating their lifetime based on the test
    data were developed. The results from these tests were compared to failure analysis
    data from long-term field operations. The findings indicate that the laboratory
    tests can accurately reproduce the main failures observed in the field. However,
    such lifetime tests can be time- and labor-intensive. To address this challenge,
    a data-driven method is proposed that predicts the lifetime of electrical connectors
    using statistical analysis of electrical contact resistance data collected from
    short-term tests. The predictions from this method were compared to actual results
    obtained from long-term tests. A strong correlation was observed between the contact
    resistance development in short-term tests and the number of failures in later
    stages of testing. Thus, apart from predicting the lifetime of connectors, this
    method can also be applied for failure prognosis in real-time operations.

  text: The state of health and lifetime estimation process of electrical connectors
    via lifetime tests is a time and labor intensive process. In our previous work,
    a correlation between the contact resistance developments in the early stages
    of lifetime tests of electrical connectors with the final results was established
    using a data driven statistical process based on probability distribution. Also,
    state of health indicators for prognosis of lifetime were introduced. In this
    work, the state of health indicators have been optimized. The sensitivity analysis
    is performed with regards to the selection of the appropriate amount of test data
    based on test duration for the reliable prognosis of the state of health and the
    characteristic lifetime. Through this the possibility of further reduction of
    test duration required for the reliable prognosis of state of health is investigated.
    Based on the results of analysis, a guideline for the determination of the duration
    of lifetime tests which lead to a reliable prediction of lifetime of connectors
    can be provided. Also, an assessment of the state of art in the prognosis of the
    lifetime of electrical connectors has been presented.
