SAFETY MONITORING METHOD AND SYSTEM FOR VEHICLE, AND DEVICE

The invention relates to the technical field of battery safety, and in particular to a safety monitoring method and system for a vehicle. The invention is intended to solve the problem that a battery cannot be continuously and safely monitored when a new energy vehicle is parked. To this end, the safety monitoring method in the invention includes: when a vehicle is in a parked state, waking up a battery management controller at specific time intervals, and obtaining status data of the battery by means of a 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 hibernation state again; or when the battery is in the anomalous state, further waking up a wireless communications network, and uploading the status data and/or an alarm signal to a remote monitoring platform by means of the wireless communications network. According to the present application, a status of a traction battery in a parked state can be continuously monitored, and in addition, data can be remotely uploaded purposefully to reduce energy consumption.
