Electric vehicle operation data recording method and device, electronic equipment and storage medium

The invention discloses an electric vehicle operation data recording method and a device thereof, electronic equipment and a storage medium. The method comprises the following steps: electric vehicle operation data is acquired; the running data of the electric vehicle is stored in a set partition of a memory of a BMS, a priority is set, and a storage time parameter of the running data of the electric vehicle is recorded; the cloud server sends a request command to the BMS, the BMS enters a set partition of the memory according to the priority to read the electric vehicle operation data and the storage time information after receiving the command, and when the time information stored in the cloud server is later than the storage time information read by the BMS, the BMS transmits the electric vehicle operation data stored in the memory to the cloud server. The electric vehicle operation data information stored in the memory is transmitted to the cloud server, so that classified storage and long-time storage of
