In this thesis, a fast charging balancing circuit for LiFePO4 battery is proposed to tackle the voltage imbalance problem among lithium battery string. During the lithium battery charging process, the occurrence of voltage imbalance will activate the fast balancing mechanism. The expected balancing circuit includes the following features:(1) handling the maximum voltage difference between the odd-numbered and even-numbered battery string without extra energy storage device, thus promoting the working efficiency; (2) requiring only one converter to complete the energy transfer for voltage balance, thus making the circuit structure simple; (3) bi-directional energy flow and electrical isolation; (4) using active power switches to complete the balance control switching, thus free from mechanic switching limitation and shrinking the circuit size; (5) applying single chip control technology and measuring the voltage of every single battery, to achieve the maximal effectiveness resulting from balanced charging. Finally, the practical application of fast balancing experiments on LiFePO4 battery pack 28.8V/2.5Ah, the experimental results verification of the balancing circuit attached fast balancing function.
