Abstract

The invention discloses a method and a device for determining structural parameters of a battery pack and electronic equipment, and aims to at least solve the problem that the durability of the designed battery pack cannot be ensured by an existing battery pack structural design method. The method comprises the steps that dynamic frequency simulation is conducted on a pre-established structure model of the battery pack based on first preset parameters, frequency response curve data of the structure model in the preset direction are obtained, and the first preset parameters comprise curve data of acceleration loads changing along with frequency in the preset direction; the method further includes performing fatigue simulation on the structural model based on a preset frequency vibration working condition parameter, a preset random vibration working condition parameter and the frequency response curve data to obtain total life damage data of the structural model under the combination of a fixed frequency vibration working condition and a random vibration working condition; and determining a target structure of the battery pack based on the total life damage data and the structure model.

Description

technical field [0001] The present application relates to the technical field of batteries, in particular to a method, device and electronic equipment for determining structural parameters of a battery pack. Background technique [0002] According to the requirements of the latest specifications for vehicle battery packs, the vibration durability of the battery pack in various road conditions needs to be considered during the development of the battery pack. Therefore, it is necessary to evaluate the vibration conditions of the battery pack during the development of the battery pack. Under the condition of life damage, the structural design of the battery pack is carried out according to the evaluation results. [0003] At present, it is usually to evaluate the life damage of the battery pack under random vibration conditions in the X, Y, and Z directions separately, and then design the structure of the battery pack according to the evaluation results corresponding to each d...
