定义
A Cell Monitoring IC is a precision analog-front-end integrated circuit designed for automotive Battery Management Systems (BMS) that continuously measures voltage, temperature, and other parameters of each lithium-ion battery cell. It ensures safe operation by detecting overvoltage, undervoltage, and thermal anomalies, and communicates data to the BMS controller via isolated communication interfaces like SPI or I2C.
工作原理
The IC uses high-precision analog-to-digital converters (ADCs) to sample cell voltages and temperature sensors. It employs balancing circuits to equalize cell charges through passive or active balancing. Data is transmitted digitally to the main BMS controller, enabling state-of-charge (SOC) and state-of-health (SOH) calculations while ensuring isolation for safety.
