The invention relates to the technical field of battery safety, and in particular to a safety monitoring method and system for a vehicle. The safety monitoring method 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.

Safety monitoring method and system for vehicle, and device

An SOC estimation method for a battery system includes mapping an upper limit and a lower limit of the state of charge of the second-system battery to a state of charge interval of the battery system, to establish a mapping relationship between the upper limit and the lower limit of the state of charge of the second-system battery and the state of charge interval of the battery system. The method includes calculating the state of charge of the second-system battery and estimating a state of charge of the battery system according to the mapping relationship.
