Summary:The invention provides a monitoring method and system for a low-voltage power supply and a vehicle, and relates to the technical field of vehicle control. The method is applied to a controller, and comprises the following steps: when a starting condition of low-voltage power supply monitoring is met, controlling a storage battery sensor to monitor a charging current of a storage battery when a whole vehicle network is dormant; when a wake-up signal sent by the storage battery sensor is received, the storage battery is awakened; and when it is determined that the charging current is abnormal according to the detection result of the charging current sent by the storage battery sensor, the whole vehicle network is awakened. By utilizing the method provided by the invention, the charging current of the storage battery can be monitored when the whole vehicle network is dormant, and the whole vehicle network can be awakened when the charging current of the storage battery is abnormal, so that the storage battery ca
