I-PEX offers a variety of connectors that are ideal for the automotive industry. Below are some use case examples for typical automotive applications such as PCU and BMS/CMU.

What is PCU? (Power Control Unit )

This is used to receive signals from vehicle and controlling IGBT module for power control.

 

What is CMU? (Cell Management Unit )

This is used for measuring and monitoring battery status. Lithium-Ion batteries need to be strictly controlled – this system/unit will shut-off power transmission for any abnormal status.

 

The ISH^® series is the best choice for these various automotive modules. I-PEX's unique spring-structured terminals provide high long-term contact reliability. The connectors also excel in high temperature resistance and vibration resistance and are available in a variety of pole numbers.
