The embodiment of the invention discloses a battery safety management control method and an electric vehicle, and the method comprises the steps: collecting a battery state parameter of a power battery of target equipment through a battery management system, and transmitting the battery state parameter to a central domain integrated control unit; the central domain integrated control unit performs a first type of fault diagnosis based on the battery state parameter; the battery management system performs a second type of fault diagnosis based on the battery state parameter to respectively obtain a first diagnosis result and a second diagnosis result; and the central domain integrated control unit responds to the first diagnosis result to carry out first response operation on the target equipment, or the battery management system responds to the second diagnosis result to carry out second response operation on the target equipment. According to the scheme, the function responsibilities of the battery management system and the central domain integrated control unit are divided, so that the battery management system reserves a data acquisition function and a partial fault logic judgment function, and the problem that a power battery cannot be quickly responded and protected when an emergency fault occurs is avoided.
本申请实施例公开了一种电池安全管理控制方法及电动车辆,方法包括利用电池管理系统采集目标设备的动力电池的电池状态参数,并将电池状态参数发送至中央域集成控制单元;中央域集成控制单元基于电池状态参数进行第一类型故障诊断电池管理系统基于电池状态参数进行第二类型故障诊断,分别获取第一诊断结果和第二诊断结果;中央域集成控制单元响应于第一诊断结果对目标设备进行第一应对操作,或,电池管理系统响应于第二诊断结果对目标设备进行第二应对操作。本申请方案,通过对电池管理系统和中央域集成控制单元的功能职责进行划分,使得电池管理系统保留数据采集功能和部分故障逻辑判断功能,避免出现紧急故障时无法迅速响应保护动力电池的问题。
