description The embodiment of the invention discloses a battery parameter updating method, a battery management platform and a vehicle, belongs to the technical field of vehicle-mounted batteries, and aims to solve the problem that a calculation result has a large error due to the fact that the calculation capability of a BMS and test parameters in an equivalent circuit model are limited. The method comprises the steps that: a battery management platform obtains the voltage of at least one battery cell in a battery of a target vehicle; when the battery event of the battery is a fast charge event, the battery management platform determines target performance evaluation parameters of the battery according to the voltage of the at least one battery cell, wherein the target performance evaluation parameters comprise ohmic internal resistance of the at least one battery cell and/or polarization degree of the at least one battery cell; and the battery management platform sends the target performance evaluation parameters to th
