A remote monitoring and alarm system of a vehicle traction battery fault of the invention includes an alarm data analysis and processing system, and the alarm data analysis and processing system includes a fault rule management module, a data parsing module, a data processing module, and a fault notification module. An operator can use the fault rule management module to adjust a determination rule in time so as to implement dynamic configuration of the determination rule, and the fault notification module sends a fault notification on the basis of alarm data obtained, by means of filtering, by the data processing module. In this way, a user and the operator can know detailed alarm data in time to perform corresponding maintenance on the vehicle traction battery in time, thereby greatly improving the safety performance of the vehicle traction battery.

This application relates to a method and an apparatus for determining a status of a battery temperature sensor, a medium, a vehicle, and a server. The method includes: receiving reading statistics of a temperature sensor that are collected at intervals of a predetermined time in a stable vehicle working condition, where the reading statistics include a highest temperature reading and a lowest temperature reading of the temperature sensor within each predetermined time; determining a highest temperature reading trend, a lowest temperature reading trend, and a largest temperature reading difference in the stable vehicle working condition based on the highest temperature reading and the lowest temperature reading; and determining a status of the temperature sensor based on the highest temperature reading trend, the lowest temperature reading trend, and the largest temperature reading difference. The method is capable of accurately determining whether a battery temperature sensor is anomalous.

The present application relates to a system and method for vehicle battery management, a storage medium, and a server system. The system for vehicle battery management includes: a communications subsystem configured to receive battery signal data in a distributed message queue; a metadata management subsystem configured to store battery information; and a distributed processing subsystem configured to parse the battery signal data based on the battery information, to obtain parsed data and alarm data. In this way, centralized battery management can be implemented, thereby overcoming disadvantages in terms of alarms/warnings generated by the batteries themselves.
