AI Technical Summary

Technical Problem

In existing technologies, when electric vehicles upgrade with cloud servers via long-term connections, there are issues such as insufficient communication protocol flexibility, excessive resource consumption, and susceptibility to network fluctuations, resulting in low upgrade efficiency.

Method used

The system uses a long connection link to receive and verify upgrade commands. Once the conditions are met, it switches to a short connection link to receive and decrypt upgrade packets. It then combines differential packet and streaming technologies to perform the upgrade, supporting breakpoint resumption and upgrade log synchronization.

Benefits of technology

It improves upgrade efficiency, reduces long-term connection resource consumption, enhances communication protocol flexibility, reduces the impact of weak network environments on the upgrade process, and improves security and user experience.

Abstract

This application provides an electric vehicle upgrade method and an electric vehicle. The method involves receiving an upgrade command from a cloud server via a long-lived connection between the electric vehicle and the cloud server. In response to the upgrade command, the method verifies the upgrade conditions of the electric vehicle based on verification information, obtains a verification result, and sends the result to the cloud server. When the verification result indicates that the electric vehicle meets the upgrade conditions, the method receives an upgrade packet from the cloud server via a short-lived connection between the electric vehicle and the cloud server, and performs the upgrade based on the upgrade packet. This application supports both long-lived and short-lived connections between the electric vehicle and the cloud server, ensuring real-time and reliable reception of upgrade commands while reducing the resource overhead of continuous long-lived connections and improving the flexibility of the communication protocol. Furthermore, this application uses a short-lived connection to receive the upgrade packet, reducing the impact of weak network environments on the upgrade process and improving upgrade efficiency.
