Abstract :
Because of overcharge for Li-ion battery is forbidden, there is no natural mechanism to equalize the difference among the cells, so effective balancing method is required to improve the performance of battery and prolong its life time. There are two classifications of balancing methods: passive balancing and active balancing. In this paper, the advantages and disadvantages of these two methods are found out.
