Pros and Cons of Active Balancing and Passive Balancing - Pete_UZ - 12-22-2022

Passive balancing results in all battery cells having a similar SoC by simply dissipating excess charge in a bleed resistor; it does not, however, extend system run time. Active cell balancing is a more complex balancing technique that redistributes charge between battery cells during the charge and discharge cycles, thereby increasing system run time by increasing the total useable charge in the battery stack, decreasing charge time compared with passive balancing, and decreasing heat generated while balancing. Generally for low power application (RESS and small C&I ESS Application) the Passive Balancing BMS is good with its low cost, small size and very simple control. Click for more
