Power battery: active equalization: adjacent pressure difference method: buck-boost.Abstract
For the electric vehicle power battery in the continuous use of the process due to inconsistency caused by the shortening of the life of the problem, put forward a hierarchical through the inductive control of the equalization method, topology using buck-boost equalization circuit hierarchical treatment of the battery pack, through the neighboring average pressure difference method of the control strategy for the overall logic of the operation, after the experimental simulation, the different state of the battery simultaneously After the experimental simulation, the equalization control within and between the battery packs for different states of batteries simultaneously, and finally can realize the power consistency relatively well, which proves that the method is feasible, can effectively improve the inconsistency of battery packs, and is more economical and reliable compared with other control methods.
