A method, a device and equipment for detecting the connection reliability of a power battery system and a vehicle, and the method comprises the steps: determining a resistance value of an electrical loop and a potential difference of a power battery in a vehicle driving process or a charging process; judging whether the connection of the power battery system is reliable or not according to the resistance value and the potential difference; and if the connection of the power battery system is not reliable, outputting information that the connection of the power battery system is not reliable. According to the information that the connection of the power battery system is unreliable, a driver can timely carry out self-inspection on the vehicle or send the vehicle to a repair factory for maintenance, so that the situation that under the condition that the connection of the power battery system is unreliable,the driver continues to drive the vehicle for a long time or charges the power battery system for a long time so that the temperature of the power battery system is raised to cause spontaneous combustion of the vehicle is avoided. Therefore, reliable technical guarantee is provided for safe driving of the vehicle, and the safety performance of the vehicle is improved.

    一种动力电池系统连接可靠性的检测方法、装置、车辆及设备,其中所述方法包括:在车辆行驶过程或充电过程中,确定所述电气回路的电阻值及所述动力电池的电位差;根据所述电阻值及所述电位差,判断所述动力电池系统连接是否可靠;若所述动力电池系统连接不可靠,则输出动力电池系统连接不可靠的信息。驾驶员可以根据所述动力电池系统连接不可靠的信息,及时对车辆进行自检或者将车辆送至修理厂进行检修,避免了车辆在动力电池系统连接不可靠的情况下,驾驶员继续驾驶车辆长时间行驶或者长时间对所述动力电池系统进行充电,导致动力电池系统温度升高,进而引起车辆发生自燃,为车辆的安全行驶提供可靠地技术保障,提升了车辆的安全性能。
