AI Technical Summary
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.
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.
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.
