The invention relates to a battery pack insulation performance monitoring method and device and a vehicle, and the method comprises the steps: receiving message data sent by a BMS in a vehicle from the power-on of the vehicle, wherein the message data comprises charging state information and insulation resistance of a battery pack; determining target message data from the received message data according to the charging state information; counting a first quantity corresponding to the target message data; under the condition that it is determined that the first number is larger than or equal toa preset number threshold value, determining the second number of specified message data from the first number of target message data according to the insulation resistance value in each piece of target message data, wherein the specified message data is message data with the insulation resistance value smaller than or equal to a preset resistance value threshold value; and determining the insulation performance of the battery pack according to the second quantity. The insulation performance of the battery pack can be determined according to the second quantity, and the insulation performanceof the battery pack can be timely and accurately monitored, so that the safety performance of a vehicle can be effectively improved.
本公开涉及一种电池包绝缘性能监测方法、装置及车辆,该方法通过从车辆上电开始接收车辆中BMS发送的报文数据,该报文数据包括电池包的充电状态信息和绝缘阻值;根据充电状态信息从接收到的报文数据中确定目标报文数据;统计目标报文数据对应的第一数量;在确定第一数量大于或者等于预设数量阈值的情况下,根据每个目标报文数据中的该绝缘阻值,从该第一数量的该目标报文数据中确定指定报文数据的第二数量,该指定报文数据为该绝缘阻值小于或者等于预设阻值阈值的报文数据;根据该第二数量确定该电池包的绝缘性能。能够根据该第二数量确定该电池包的绝缘性能,能够及时准确地监测电池包的绝缘性能,从而能够有效提升车辆的安全性能。
