6 FAQs about [Battery pack high voltage connector failure]
What causes a battery pack contactor to fail?
There are a number of reasons for contactor failure: There are a number of companies that make contactors, some are electro-mechanical, solid state and a mix of both technologies. When the battery pack contactors are closed onto a motor and inverter there will be an inrush of current into the inverter capacitor.
What causes a battery pack to fail?
An analysis of battery pack functions, failure modes, causes, and effects concerning their severity, occurrences, and detection ranks. The most important causes of failure are sealing, BMS, structure design and assembly of mechanical components. Using fuzzy inference engine, the RPN values are modified to improve the FMEA.
What happens if a battery pack contactor is closed?
When the battery pack contactors are closed onto a motor and inverter there will be an inrush of current into the inverter capacitor. This very high current is at a minimum likely to age the contactors, it could permanently damage the contactors. Therefore, when we closed the contactors on the battery pack we do this in three steps:
How does the ICBP affect battery pack performance?
Signal and voltage inputs can affect battery pack performance. Clogs and failures in the water flow path can reduce the cell's life and increase the fire risk. The ICBP uses system inputs to function correctly, including CAN, KL30, and KL15 signals and external fluid from the chiller.
