Comparison of active and passive battery balancing

The presented BMS is universal and can be used for most applications using a combination of 15 LiFePo4 type accumulators, which are the most often accumulator type in home battery storage systems. Therefore, the presented system is intended for home battery storage by default. This paper focuses on comparison of two most common balancers for equalizing accumulated charge in cells. The systems are compared with each other in terms of efficiency, complexity and the time required to balance the accumulator.
