What is Voltage Threshold-Based Cell Balancing in Battery BMS?
Voltage threshold-based cell balancing in Battery BMS involves balancing individual cells within a battery pack using voltage thresholds. By setting the termination voltage for each cell lower than the overall pack-based threshold divided by the number of cells, voltage differences are created to enable cell balancing. This method ensures that the cells operate within safe voltage limits and maximizes the performance and lifespan of the battery pack.
Voltage Threshold-Based Cell Balancing is a smart technique used in Battery Management Systems (BMS) to ensure that each cell within a battery pack operates efficiently. By constantly monitoring the voltage levels of individual cells, this method aims to equalize their charge states.
When one or more cells reach a predetermined voltage threshold, the BMS kicks into action. It initiates a balancing process by diverting excess energy from higher-voltage cells to lower-voltage ones. This helps maintain uniformity among all cells and prevents overcharging or undercharging.
In essence, Voltage Threshold-Based Cell Balancing acts as a vigilant guardian, ensuring that no cell in the battery pack is left behind or pushed beyond its limits. It plays a crucial role in optimizing battery performance and extending its overall lifespan.
