Abstract: A battery charging progress prediction method and apparatus are provided. One example method includes: receiving a request message from a first terminal or a second terminal, where the request message includes a battery model of a battery of the first terminal and a first state of charge (SOC); determining charging progress information of the battery of the first terminal based on the request message; and sending a response message to the first terminal or the second terminal, where the response message includes the charging progress information.

Abstract: Embodiments of this application provide a charging control method, apparatus, and system, a server, and a medium. In an example method, a generation sequence of a charging policy stored in a first terminal and a generation sequence of a charging policy stored in a second terminal are compared in the first terminal, to determine a relatively new charging policy in the first terminal and the second terminal as a target charging policy. The target charging policy may subsequently configure a charging parameter, so that the charging parameter configured in a charging process is adapted to a current performance status of a power battery of a vehicle.

Abstract: A fault root cause analysis method and apparatus are provided. The method includes: obtaining a first alarm event set, where the first alarm event set includes a plurality of alarm events; for a first alarm event in the first alarm event set, extracting a feature vector of the first alarm event, where a part of or all features of the feature vector are used to represent a relationship between the first alarm event and another alarm event in the first alarm event set; and determining, based on the feature vector of the first alarm event, whether the first alarm event is a root cause alarm event. In this application, whether the first alarm event is the root cause alarm event is determined based on a feature vector of the relationship between the first alarm event and the another alarm event, and the accuracy of fault root cause identification is improved.
