The embodiment of the invention provides a battery pack safety state scoring method, device and equipment and a readable storage medium, and belongs to the technical field of battery safety. The method comprises the steps that a vehicle-mounted battery management system collects battery pack state data at a certain moment within a preset time and uploads the battery pack state data to a vehicle-mounted terminal, and the vehicle-mounted terminal uploads the battery pack state data to a cloud platform; the cloud platform receives the battery pack state data and preprocesses the battery pack state data; extracting characteristic factors according to the preprocessed battery pack state data; constructing a first feature matrix according to the feature factors corresponding to the battery pack state data at different moments, and performing dimension reduction processing on the first feature matrix to obtain a second feature matrix; and according to the second feature matrix, constructing a differential feature model, and according to all the battery pack state data within the preset time, outputting a battery pack safety state score by the differential feature model. Through the provided scheme, the change state of the battery pack is quantified, and the safety coefficient of the battery is improved.

    本申请实施例提供了一种电池组安全状态评分方法、装置、设备及可读存储介质,属于电池安全技术领域。其中方法包括:车载电池管理系统采集预设时间内某一时刻的电池组状态数据,并将其上传至车载终端,车载终端将其上传至云端平台;云端平台接收电池组状态数据,并将其进行预处理;根据预处理后的电池组状态数据,提取特征因子;根据不同时刻的电池组状态数据对应的特征因子,构建第一特征矩阵,并对第一特征矩阵进行降维处理得到第二特征矩阵;根据第二特征矩阵构建差异化特征模型,差异化特征模型根据预设时间内的所有电池组状态数据,输出电池组安全状态评分。通过所提供的方案,对电池组的变化状态进行量化,提高电池安全系数。
