Abstract

See full text

The invention relates to the field of vehicle battery monitoring technologies, and in particular to a monitoring method, apparatus, and system for a low-voltage vehicle battery, a server, and a medium, to solve a technical problem that a capacity of an existing low-voltage vehicle battery drops too much, which causes a vehicle to fail to be started. For this purpose, the monitoring method according to embodiments of the invention includes the following steps: step S101: obtaining, in response to a received battery anomaly analysis request, an electric energy-related parameter of the low-voltage vehicle battery from the battery anomaly analysis request; and step S102: determining, based on a result of comparison between the electric energy-related parameter and a preset electric energy parameter threshold, whether a capacity of the low-voltage vehicle battery is anomalous, where the battery anomaly analysis request is request information output by a vehicle device during a vehicle standstill and when it is detected that a battery voltage of the low-voltage vehicle battery is less than or equal to a preset voltage threshold. Through the foregoing steps, the low-voltage vehicle battery whose capacity is anomalous can be identified in advance, so that a user can take measures in time.
