The invention relates to a battery cell equalization method and device, a battery cell equalization circuit, a battery management system, a vehicle and a readable medium. The battery cell equalization method comprises the following steps: determining whether to execute equalization operation for a target battery cell of a battery module or not according to working conditions of the battery module and each battery cell of the battery module; if it is determined that the equalization operation for the target battery cell is executed, the intensity of the equalization operation is determined according to the voltage difference value of the voltage of the target battery cell relative to the voltage difference value of other battery cells in the battery module, and the intensity of the equalization operation comprises the number of channels for executing the equalization operation; the channel comprises a resistor for dissipating the energy of the target battery cell; and executing the equalization operation according to the determined intensity of the equalization operation. According to the battery cell equalization method provided by the invention, equalization of the target battery cell in the battery pack can be realized in an elastic manner.
