Figure 1: BMS Architecture One of the most important parameters for a BMS is the accuracy of its state-of-charge (SOC) estimation. Errors in. .
The battery monitor and protector is the IC responsible for sensing the battery’s voltage, current, and temperature. These measurements are. .
The fuel gauge is the IC tasked with calculating the battery’s estimated SOC. Fuel gauge algorithms can be deployed in the main MCU, but a dedicated fuel gauge IC has many advantages, including: Efficiency: Fuel gauges reduce the MCU’s computation. .
In conclusion, accurate estimation of a battery’s SOC is key for any battery-powered application, and it is the BMS designers’ task to optimize the tradeoff between SOC. [pdf]
