The embodiment of the invention provides an active equalization method and system and a computer readable storage medium, and belongs to the technical field of equalization units. The active equalization method comprises the following steps: establishing a mathematical model based on inductance energy transfer equalization topology according to an equalization circuit; determining the current state quantity of each single battery of the battery pack according to the mathematical model; determining the theoretical state quantity of each single battery when the current system normally operates; judging whether the battery pack needs to be balanced or not according to the current state quantity and the theoretical state quantity of each single battery; and balancing the battery pack until the battery pack does not need to be balanced under the condition that the battery pack needs to be balanced. The active equalization method is high in equalization efficiency. 本发明实施例提供一种主动均衡方法、系统及计算机可读存储介质，属于均衡单元技术领域。所述主动均衡方法包
