Cell Sampling Harnesses
The Cell Sampling Harness is used to collect real-time individual cell voltage and temperature signals from a multi-series lithium battery pack and transmit them to the Battery Management System (BMS).
Communication, Control and Auxiliary Harnesses
The internal flat ribbon cable is used for signal transmission between the main BMS control board and the interface or adapter board. It enables coordinated operation of internal functional modules and ensures reliable communication within the BMS system. This cable is for internal system integration and is not intended for external user connection.
