Abstract

The invention provides a battery performance parameter determination method and device, equipment and a medium, and the method comprises the steps: obtaining the temperature of each unit battery based on a preset battery temperature distribution model; wherein the battery is formed by connecting all the unit batteries in parallel; determining a performance parameter of each unit battery corresponding to the temperature of each unit battery based on a preset corresponding relationship between the temperature of the battery and the performance parameter; and obtaining the performance parameter of the battery according to the performance parameter of each unit battery. By adopting the embodiment of the invention, the battery can be equivalent to a plurality of unit batteries with different temperatures, and the performance parameters of each unit battery are calculated, so that the performance parameters of the original battery are more accurately calculated, and the problem that the temperature inconsistency of the same battery at different positions is not considered in the prior art is solved; and more accurate battery performance parameters are obtained.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a method, device, equipment and medium for determining battery performance parameters. Background technique [0002] The battery is one of the main energy carriers and power sources of electric vehicles, and it is also one of the important components of the electric vehicle body. In order to use the battery effectively, reasonably and safely, it is necessary to accurately determine the battery during the use of the battery. performance parameters. [0003] However, the inventors found in the research of the prior art that at present, the relevant performance parameters of the battery are directly calculated according to the ambient temperature or the measured temperature of the battery, without considering the problem of inconsistency in the temperature of the same battery at different locations, and it is impossible to obtain a comparative Accurate performance parameters.
