The invention provides a battery pack health detection method and device, and the method comprises the steps: reading battery pack self-detection data of a target vehicle when a battery pack of the target vehicle is charged and is in a battery pack health self-detection mode; judging whether the self-inspection data accords with a first preset threshold range or not; if yes, requesting a battery management system of the target vehicle to charge the battery pack according to a preset charging current scheme; after the charging process of the battery pack is finished, acquiring health data of the battery pack in the charging process; uploading the health data of the battery pack to a big data center for battery health diagnosis; and when a feedback result fed back by the big data center is received, updating the charging current scheme according to the feedback result. Therefore, the method can accurately detect the health state of the battery, is suitable for real vehicle testing, and is short in testing time and high in accuracy.

    本申请提供一种电池包健康检测方法及装置,该方法包括:当目标车辆的电池包在充电且处于电池包健康自检模式时,读取目标车辆的电池包自检数据;判断自检数据是否符合第一预设阈值范围;如果是,则请求目标车辆的电池管理系统按照预设的充电电流方案对电池包进行充电;当电池包结束充电过程后,获取充电过程的电池包健康数据;将电池包健康数据上传至大数据中心进行电池健康诊断;当接收到大数据中心反馈的反馈结果时,根据反馈结果对充电电流方案进行更新。可见,该方法能够精确检测电池健康状态,适用于实车测试,测试时间短,精度高。
