The invention relates to the technical field of battery detection, and provides a temperature detection method and device for a power battery. The method comprises the following steps: acquiring a current vehicle state parameter of a target vehicle; determining a temperature index corresponding to the current vehicle state parameter based on a preset mapping relation between the vehicle state parameter and the temperature index of the power battery; acquiring the current battery temperature of the power battery; and judging whether the current battery temperature meets various temperature indexes or not, and generating a temperature detection result according to all judgment results. According to the method, the more reliable and meticulous temperature index is determined through the current vehicle state parameter to detect the current battery temperature, the temperature index is correspondingly adjusted along with the vehicle state parameter and is not kept constant, whether the current battery temperature is normal or not can be sensitively fed back, and the temperature detection result with more reference value is generated; and temperature abnormity can be prompted in time.

    本申请涉及电池检测技术领域,提供了一种动力电池的温度检测方法及装置。该方法包括:获取目标车辆的当前车辆状态参数;基于车辆状态参数与动力电池的温度指标之间的预设映射关系,确定当前车辆状态参数对应的温度指标;获取动力电池的当前电池温度;判断当前电池温度是否满足各项温度指标,并根据所有判断结果生成温度检测结果。本申请通过当前车辆状态参数确定更为可靠细致的温度指标用于检测当前电池温度,温度指标随着车辆状态参数相应调整,不再保持恒定不变,能够灵敏地反馈当前电池温度是否正常,并生成更有参考价值的温度检测结果,以便及时提醒温度异常。
