The invention relates to a vehicle power shortage monitoring method and system and a medium. The method comprises the steps that a main node of a vehicle-mounted controller monitors a unit quiescent current consumption value of a storage battery of a current vehicle when the current vehicle enters a dormant state; when the unit quiescent current consumption value is greater than or equal to a preset unit quiescent current consumption value, the main node sends an awakening signal to a slave node of a vehicle-mounted controller; after the main node awakens the slave node through the awakening signal, the slave node judges whether abnormal awakening exists or not before receiving the awakening signal; if so, the slave node acquires own abnormal wake-up time and abnormal wake-up reason; and the slave node creates a DID of the slave node, and records the identifier of the slave node with abnormal wake-up, the abnormal wake-up time, the abnormal wake-up reason and the vehicle state data during abnormal wake-up in the DID created by the slave node. By implementing the method provided by the invention, the problem that the reason of power shortage of the vehicle is difficult to check canbe solved.
Description
technical field [0001] The invention relates to the field of vehicle accumulators, in particular to a vehicle power loss monitoring method, system and medium. Background technique [0002] After the vehicle battery loses power, it will cause the electrical appliances on the vehicle to be unable to work normally. When the battery is severely depleted, it will even cause the vehicle to fail to start normally and the vehicle will break down. Therefore, it is very important to analyze the reasons that may cause the vehicle battery to lose power. important. [0003] The power loss of the vehicle battery is often related to the user's usage habits, for example, the user does not use the vehicle for a long time, starts or stops frequently, drives at low speed or idles for a long time, etc. The existing analysis of the cause of battery power loss mainly includes four steps: look, smell, ask, and cut. The first is to observe whether useful electrical appliances are still used after...
