The invention discloses a high-voltage connector loosening fault detection method and device and an automobile. The method is applied to a battery management system BMS, the BMS is connected with a high-voltage load through a high-voltage connector, the first connecting end of the high-voltage connector is connected with the BMS, and the second connecting end of the high-voltage connector is connected with the high-voltage load. The method comprises the steps of acquiring a first voltage value of the first connecting end of the high-voltage connector and a second voltage value of the second connecting end of the high-voltage connector; and performing loosening fault detection of the high-voltage connector according to the first voltage value and the second voltage value. According to the high-voltage connector loosening fault detection method, the connection reliability of the high-voltage connector is accurately detected in real time, and the thermal accident risk caused by looseningof the high-voltage connector of a battery is avoided.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a detection method and device for a high-voltage connector loose fault and an automobile. Background technique [0002] The battery that provides the power source for the vehicle in the new energy vehicle is called the power battery. The power battery is the core component of electric vehicles. Its function is to receive and store high-voltage direct current provided by on-board chargers, generators, braking energy recovery devices or external charging devices, and to provide high-voltage direct current for electric vehicles. [0003] The high-voltage and high-power connection terminal (high-voltage connector) output by the power battery may become loose after the vehicle runs for a long time or the battery output terminal is hit by an external force, resulting in an increase in the resistance of the connection position. If the battery pack continues to use a large current D...
