Abstract

The invention discloses a storage battery power shortage early warning method, device and system, and relates to the technical field of automobiles, and the method comprises the steps: extracting fault feature data from monitored vehicle state data; according to the fault feature data, determining low-voltage power-lack fault factors; and outputting prompt information according to the low-voltage power-lack fault factors. According to the scheme, the potential low-voltage power shortage risk of the vehicle is monitored in real time, the user is guided to operate correctly, the phenomenon that travel of the user is blocked due to low-voltage power shortage of the vehicle is avoided, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of automobiles, and in particular, to a method, device and system for early warning of battery power loss. Background technique [0002] In recent years, the state has vigorously supported new energy vehicles, and electric vehicles have entered thousands of households. With the widespread use of electric vehicles, the problems of electric vehicles have also become prominent. One of the more common types of faults is low-voltage and under-voltage faults, that is, the whole vehicle After a period of time after the electric vehicle is locked, the battery will be depleted, which will cause the vehicle to fail to start. In general, the vehicle needs to be started by connecting the 12V low-voltage power supply to the outside of the electric vehicle. However, this method wastes time and costs. question. SUMMARY OF THE INVENTION [0003] The purpose of the present application is to provide a battery pow...
