| description | A battery array equalization circuit comprises a controller, an energy storage component, a first bus, a second bus, and at least two battery equalization modules. The layout and connection relation of the multiple battery equalization modules are as follows: the vertically arranged battery equalization modules are sequentially connected in series into battery equalization module groups, the laterally arranged battery equalization module groups are connected in parallel with the two ends of the energy storage component. The controller is connected with the control ends of the battery equalization modules. Each battery equalization module comprises four switch tubes, a storage battery and a voltage sensor. The invention further provides a battery equalization method, which specifically includes a same-branch battery equalization method and a cross-branch battery equalization method. Equalization of any two batteries in a battery array is realized, and positive-negative adjustment of theoutput voltage of the ba |
