The invention belongs to the technical field of lithium battery health management, and provides a charging health management method and system for a vehicle lithium battery and charging equipment, and the method comprises the steps: determining the internal temperature of a battery pack and the internal temperature rise rate of the battery pack through a three-dimensional thermal imaging technology, and if the detected environment temperature is higher than a preset value, stopping the charging of the vehicle lithium battery; a preset battery pack protection bottom plate cooling strategy is used for cooling the battery pack protection bottom plate, and the situation that the judgment precision of the thermal imaging technology on the battery temperature is affected due to the fact that the temperature of the protection bottom plate is too high is avoided; meanwhile, if the internal temperature of the battery pack exceeds a preset temperature value or the temperature rise rate exceeds a preset rate value, charging health management is carried out by utilizing preset charging management, and natural problems of the battery pack caused by too high temperature are avoided by judging the internal temperature and the temperature rise rate of the battery pack; meanwhile, the problem that the charging time is prolonged when the temperature of the battery pack is excessively reduced is avoided.

    本发明属于锂电池健康管理技术领域,提供了一种车用锂电池的充电健康管理方法、系统及充电设备,利用三维热成像技术确定电池包内部温度,以及电池包内部的升温速率,同时如果检测的环境温度高于预设值时,利用预设的电池包护底板降温策略,对电池包护底板进行降温,避免了护底板温度过高而影响热成像技术对电池温度的判断精度;与此同时,如果电池包内部温度超过预设温度值,或所述升温速率超过预设速率值,则利用预设的充电管理进行充电健康管理,通过对电池包内部温度和升温速率的判断,避免了温度过高引起的电池包自然问题,同时避免了过度降低电池包温度时延长充电时间的问题。
