The invention discloses a liquid cooling pipeline flow adjusting system and method for a power battery of a pure electric bus, relates to the technical field of electric automobiles, and solves the problems that in the prior art, when the temperature change rate is large, a branch cannot reach the required flow in time, so that the cooling effect of the battery is poor, and the service life of the battery is prolonged. And the efficiency of the liquid cooling pipeline flow adjusting system is low. The method comprises the steps of calculating instantaneous heat production of a plurality of batteries according to battery data; a main path cold liquid estimated flow is generated according to the instantaneous heat production amount; the main path valve body opening degree is generated according to the main path cold liquid estimated flow; according to the battery temperature, branch cold liquid flow is generated, and the branch valve body opening degree is calculated; the alarm signal is generated according to the instantaneous heat production amount and the battery temperature, the required total cold liquid flow amount is estimated according to the heat production amount of the battery, and the required total amount is introduced into each branch in advance, so that the battery can be cooled by the required flow in time when the branch calculates the flow, and the efficiency of the liquid cooling pipeline flow adjusting system is improved.
