Battery Management ICs
Battery management system refers to the electronics that deliver information to the host system about status of the battery like state of charge and state of health information and perform the cell management.
Certain battery cell chemistries may become unstable in case of over voltage, charging after under voltage or overcurrent. Therefore, the Battery Management System is there to ensure that the cells in the system are always operated inside the SOA of the given chemistry. Infineon products contribute by providing voltage of each cell and temperature measurement through external resistor (NTC), the cell balancing as well as communicating the measurement results and diagnostic information to the main microcontroller.
Infineon´s Battery Management System devices family is designed and engineered for systems to support 800V and above. Infineon devices can be operated either directly from microcontroller by using UART or through iso UART interface by using the BMS transceiver IC which enables a galvanically isolated communication interface by inductive or capacitive coupling.
Yes, Infineon´s Battery Management System products have been designed fulfilling the highest quality standards and finally qualified according AEC Q100 qualification standard.
