A battery-effect analysis is a method for identifying and understanding potential failure modes in the internal system of a battery. But how do you perform this procedure? In Part 1 of this article series, the valuable work that creates in front of the ground work for the identification of potential problems. In the next part of the series we will learn how to measure to battery mode and severity occurring. As a reminder, we found that a mode and effects analysis includes fourStages or phases, including:
Fashion Pre-work - partly explains 1MOD SeverityMode OccurrenceMode Detection
Fashion Severity
Identify battery failure severity assessment and subsequent evaluation of the severity or score of all non-modes and their effects - includes both directly and indirectly. In order to assess all potential failure modes in a battery system, it is important to note the battery performance specifications designed. Good to know in advance how the battery should leaddeveloped specifications is proving extremely useful in determining any potential botched mode.
Possible interference mode could reduce, distort, are incompatible, misuse or abuse, faulty algorithms, excessive voltage, improper operating conditions, faulty or weak internal system hardware, etc. Furthermore, otherwise mode have a direct and indirect relationship with an effect. For example, the causality of a failure mode, an electrical short circuit couldCorrosion or deformation.
The causality is, therefore, is what has made in terms of severity. More to the point, every non-mode, a deficiency influences the function of the battery system. The effect is to use felt. If the battery is user experience, "x" failure effect then, the severity of the impact can be assessed 1 to 10 (severity of 10 is the most extreme and is usually for damages, which a user is reserved).
An indication of the severity ratings is that it could oneConsequential effect of the failed battery to power systems. In other words, a battery can not properly carry out or be included fully into its own system. Depending on the severity of the disorder, the effects can go beyond system boundaries of the battery. Conversely, failure, and just as important in determining the cause of the battery is the direct and indirect effects of the interface system - whereas the connection system may cause a disturbanceBattery.
Fashion occurrence
The next phase of the failure mode and effects analysis is the occurrence pattern of the battery. Quite simply - the emergence of patterns evaluated how often an error occurs. Since the batteries are not as weak design, it is important to know the type, the effect will be considered, and denied the frequency of a battery. In this way, can change a design to be made and money can be saved.
To measure a frequency of a defect mode, you can review similar productFailure events, processes or data (if previous examples are available) can be used. Or, if previous examples are not available, then a trial-and-error process could be conducted. Why this is important - because if a battery over time is not in the zone 8-10 then assesses a person can bet life is to lose, limb, property or somewhere. And of course you would not want a lot of entries at this level of severity.
