The horizontal axis of the estimated battery cell temperature rise curve may be time information, and the vertical axis may be battery cell temperature information.
When the estimated battery core temperature rise curve is named, naming can be carried out according to the battery core initial temperature and the environmental information.
The process of generating the predicted cell temperature rise curve may be:
calling a matched historical temperature-rising curve from a historical battery cell temperature-rising curve library according to the current battery cell temperature and the current environment information, and then modifying the historical temperature-rising curve to generate the estimated battery cell temperature-rising curve; for example: selecting a historical temperature-increasing curve with the current cell temperature and the current environment information from a historical cell temperature-increasing curve library, or selecting the historical temperature-increasing curve with the minimum difference value between the current cell temperature and the current environment information as the matched historical temperature-increasing curve if all the historical temperature-increasing curves in the historical cell temperature-increasing curve library have no current cell temperature and no current environment information.

Or alternatively
If each historical battery cell temperature-increasing curve is named according to the initial temperature of the battery cell and the environmental information, the current temperature of the battery cell and the current environmental information can be matched with the names of the historical battery cell temperature-increasing curves, and therefore the matched historical temperature-increasing curves can be obtained.
Or alternatively
The current cell temperature and the current environment information can be input into a cell temperature-rising curve training model, so that the estimated cell temperature-rising curve is output through the training model.
