1. A safety monitoring method for a vehicle, wherein the safety monitoring method comprises:
when a vehicle is in a parked state, a battery management controller waking up itself from a hibernation state to a non-hibernation state at specific time intervals, and obtaining status data of a battery by means of the battery management controller;
determining, based on the status data, whether the battery is in an anomalous state; and
when the battery is not in the anomalous state, controlling the battery management controller to enter the hibernation state again; or
when the battery is in the anomalous state, further waking up a wireless communications network from the hibernation state, and uploading the status data and/or an alarm signal to a remote monitoring platform by means of the wireless communications network;
wherein the battery management controller is always in a power-supplied state, and controls itself to switch from the hibernation state to the non-hibernation state, the battery management controller is a controller running a battery management system.
