The invention discloses a vehicle battery charging monitoring method and device and a cloud battery management platform, and relates to the technical field of battery management. The charging monitoring method comprises the steps that in the process of charging a vehicle, whether a battery management system for managing a battery pack fails or not is determined based on the current maximum charging and discharging amount, a fixed current value and the actual charging duration; when the failure of the battery management system is determined, determining the standard charging duration for charging the battery pack based on the current maximum charge and discharge quantity, the fixed current value and the actual charge electric quantity of the battery pack in the charging process; and on the basis of the standard charging duration and the fault charging time node when the battery management system fails, determining the overcharge threshold time corresponding to the battery pack. According to the invention, overcharging of the battery pack can be stopped when the battery management system fails, so that the safety of the battery pack in the charging process is improved.
本申请公开一种车辆电池的充电监测方法、装置及云端电池管理平台,涉及电池管理技术领域。充电监测方法包括:在对车辆进行充电的过程中,基于当前的最大充放电量、固定电流值以及实际充电时长,确定管理电池包的电池管理系统是否失效;在确定电池管理系统失效时,基于当前的最大充放电量、固定电流值以及电池包在充电过程中的实际荷电电量,确定对电池包进行充电的标准充电时长;基于标准充电时长和电池管理系统在失效时的故障充电时间节点,确定电池包对应的过充阈值时间。本申请能够在电池管理系统失效时,停止对电池包的过充电,提升了电池包在充电过程中的安全性。
