Abstract

The invention discloses a battery pack sealing parameter determination method and device and electronic equipment, and relates to the technical field of electric vehicles. The method comprises the steps that on the basis of the same first preset parameter, parameter values corresponding to a second preset parameter are sequentially traversed according to a preset first stepping value, and the second preset parameter is the pre-tightening force of fasteners adopted for fixing an upper cover plate, a sealing material layer and a lower body when the battery pack is sealed, and the first preset parameter is the interval between the adjacent fasteners on the battery pack; in the traversing process, the parameter value meeting the first compression amount requirement serves as a target value ofthe second preset parameter, and traversing of the parameter value corresponding to the second preset parameter is stopped; and a fastener used for sealing the battery pack is determined according tothe target value of the second predetermined parameter.

Description

technical field

[0001] The present application relates to the technical field of electric vehicles, in particular to a method, device and electronic equipment for determining sealing parameters of a battery pack. Background technique

[0002] With the increasing maturity of new energy technology, new energy vehicles have gradually entered the public's field of vision. As a battery-powered vehicle, the stability and safety of the battery system directly affect the performance of the vehicle.

[0003] At present, the power battery pack is generally installed on the bottom of the vehicle body, and the working environment is relatively harsh. For this, in order to make the battery pack work in a relatively safe sealed structure, simple theoretical estimation and benchmarking are usually used to determine the sealing parameters, and then cooperate with samples Experiment to complete the sealed design of the battery pack.

[0004] However, in the aforementioned battery pack seali...
