In one embodiment, the detecting a cell temperature of a battery inserted into a battery replacing bin in the battery replacing cabinet includes:

A trades the electricity cabinet and can have a plurality of trades the electricity storehouse, like 9 or 4, correspondingly, but usable battery also has a plurality ofly in a trades the electricity cabinet, and for convenience of customers trades the electricity, only does not have the battery in 1 trades the electricity storehouse in every trades the electricity cabinet to make things convenient for the user to insert the battery of its used electric motor car in this vacant trades the electricity storehouse, like this, vacant trades the electricity storehouse and just retrieves user's male battery, meanwhile, trades the electricity cabinet and can pop out the battery that the electric quantity is the highest according to the electric quantity condition of each battery in other trades the electricity storehouse and trade the electricity for the user.

Because there are a plurality of batteries available in one power change cabinet, when detecting the cell temperature of the battery, the cell temperatures of the batteries respectively inserted into the plurality of power change bins in the power change cabinet can be automatically detected respectively, so as to determine the temperature of each battery cell.

In one embodiment, the acquiring the current environment information of the power change cabinet includes:

the temperature sensor of the electricity-changing cabinet can be positioned outside the electricity-changing cabinet or inside the electricity-changing cabinet, and can be 1 or more.

If the current environment temperature is lower than the preset environment temperature, the current environment temperature is too low, the battery temperature is possibly too low, the battery is not favorable for charging and use, and therefore the winter mode can be automatically entered;

the preset geographical area may be a location with a poor environment, such as a cold place, and the preset time range may also be a time in winter, a cold month, and the like, so that if the current location information is located in the preset geographical area and/or the current time information is located in the preset time range, it indicates that the environment where the electricity-exchanging cabinet is located is not ideal, and the current location information is relatively cold, and thus, the winter mode may be automatically entered to prepare for heating and charging the battery.

After the battery is heated, an estimated battery core temperature rise curve can be automatically generated, and then a key temperature point and/or a key time point which are suitable for controlling the stopping of heating the battery in the estimated battery core temperature rise curve are obtained, so that the heating is automatically stopped after the actual temperature point reaches the key temperature point and/or the actual time point reaches the key time point, and the influence on the service life of the battery due to the overheating of the battery is avoided.

In one embodiment, the generating an estimated cell temperature increase curve includes:

After the battery is heated based on the battery core temperature detection result, a pre-estimated battery core temperature rise curve can be automatically and accurately generated according to the current battery core temperature of the battery and the current environment information, so that the battery heating process can be accurately controlled.

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.

And modifying the historical temperature-rising curve is to modify the matched historical temperature-rising curve according to the difference so as to obtain the estimated battery core temperature-rising curve.

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.
