[0030] In the above operating environment, the embodiment of the present application provides a method for determining the type of temperature sensor. Figure 2 is a flow chart of a method for determining the type of a temperature sensor according to an embodiment of the present application. Figure 2 As shown, the method includes the following steps:

[0031] Step S202: Acquire multiple first temperature values ​​predicted by multiple simulation models at a first moment, wherein the multiple simulation models are respectively established based on the initial temperatures of multiple temperature sensors set in the energy storage system, and the first moment is any moment when the energy storage system is in a charging state or a discharging state.

[0032] The method for determining the type of temperature sensor provided in the embodiment of the present application is applicable to energy storage systems and products that apply or include energy storage systems. In step S202, when the energy storage system or the product that applies or includes the energy storage system is in a charging state or a discharging state, the temperature of the same energy storage system or the same product that applies or includes the energy storage system at any time (i.e., the first time) is predicted using multiple different established simulation models to obtain a predicted temperature value (i.e., the first temperature value).

[0033] Step S204 : determining a plurality of second temperature values ​​of the plurality of temperature sensors at the first moment according to attribute information corresponding to the plurality of temperature sensors, wherein the attribute information is used to indicate a relationship between a temperature sensing temperature and a resistance value of the temperature sensor.

[0034] In step S204, a reference temperature value (i.e., a second temperature value) is obtained at the same moment (i.e., the first moment) when the temperature of the energy storage system or a product that applies or includes the energy storage system is predicted using the prediction model. The reference temperature value is a temperature value calculated by the battery management unit (BMU) based on the relationship between the temperature sensing temperature and the resistance value of the temperature sensor, combined with other factors that affect the temperature sensing temperature of the temperature sensor. Since the relationship between the temperature sensing temperature and the resistance value (i.e., attribute information) of different types of temperature sensors is different, the reference temperature values ​​(i.e., second temperature values) of different types of temperature sensors are also different.

[0035] Step S206 : Compare the first temperature value and the second temperature value corresponding to each temperature sensor respectively to obtain a first comparison result.

[0036] In step S206, the multiple predicted temperature values ​​(i.e., multiple first temperature values) obtained by predicting the same energy storage system or the same product by multiple simulation models in step S202 are compared with the reference temperature values ​​(i.e., second temperature values) of each type of temperature sensor to obtain a comparison result; wherein the comparison result is used to indicate whether the same predicted temperature value (i.e., first temperature value) and reference temperature value (i.e., second temperature value) exist.

[0037] Step S208: Determine the type of the temperature sensor in the energy storage system according to the first comparison result.

[0038] In step S208 , the type of the temperature sensor in the energy storage system or in the product that applies or includes the energy storage system is determined according to the result obtained in step S206 .

[0039] According to an optional embodiment of the present application, multiple simulation models are established by the following method: obtaining multiple initial temperatures of multiple temperature sensors included in the energy storage system before charging or discharging, and multiple sets of correspondences between the operating time of the energy storage system and the heat dissipation; and establishing multiple simulation models based on the multiple initial temperatures and the multiple sets of correspondences.

[0040] In this embodiment, the simulation model mentioned in step S202 is established by the following method: before the energy storage system or the product that applies or includes the energy storage system is charged or discharged, the temperature value of the temperature sensor in the energy storage system or the product that applies or includes the energy storage system is obtained as the initial temperature; and the operating time of the energy storage system recorded in the historical data, as well as the heat dissipation of the energy storage system or the product that applies or includes the energy storage system under different operating times, are obtained to determine the relationship between the operating time and heat dissipation of the energy storage system or the product that applies or includes the energy storage system; based on the initial temperatures of multiple different energy storage systems (or products) and the relationship between the operating time and heat dissipation of multiple groups of energy storage systems (or products), multiple different simulation models corresponding to energy storage systems (or products) using different types of temperature sensors are established. Among them, an energy storage system uses only one type of temperature sensor, and the simulation models corresponding to energy storage systems (or products) using the same type of temperature sensor are the same, while the simulation models corresponding to energy storage systems (or products) using different types of temperature sensors are different.

[0041] Determining the type of the temperature sensor in the energy storage system based on the first comparison result mentioned in step S208 includes the following steps: if the first comparison result indicates that there are multiple temperature sensors whose corresponding first temperature values ​​and second temperature values ​​are equal, determining the type of the temperature sensor in the energy storage system according to a first determination strategy; if the first comparison result indicates that there is no temperature sensor whose corresponding first temperature value and second temperature value are equal, determining the type of the temperature sensor in the energy storage system according to a second determination strategy.

[0042] In this embodiment, if the comparison result obtained by comparing multiple predicted values ​​(i.e., first temperature values) and multiple reference temperature values ​​(i.e., second temperature values) is that there are multiple groups of corresponding equal predicted values ​​(i.e., first temperature values) and reference temperature values ​​(i.e., second temperature values), the type of temperature sensor used in the energy storage system (or product) is determined by an iterative screening method (i.e., a first determination strategy); if the comparison result obtained by comparing multiple predicted values ​​(i.e., first temperature values) and multiple reference temperature values ​​(i.e., second temperature values) is that there are no equal predicted values ​​(i.e., first temperature values) and reference temperature values ​​(i.e., second temperature values), the type of temperature sensor in the energy storage system is determined by a second determination strategy.

[0043] According to some optional embodiments of the present application, the type of temperature sensor in the energy storage system is determined according to a first determination strategy, including: determining a first temperature value and a second temperature value that are equal in numerical value, and determining a simulation model corresponding to the first temperature value and a temperature sensor corresponding to the second temperature value; obtaining a third temperature value predicted by the simulation model corresponding to the first temperature value at a second moment, and determining a fourth temperature value of the temperature sensor corresponding to the second temperature value at a second moment based on attribute information of the temperature sensor corresponding to the second temperature value, wherein the second moment is any moment different from the first moment when the energy storage system is in a charging state or a discharging state; comparing multiple third temperature values ​​with multiple fourth temperature values ​​to obtain a second comparison result, and determining the type of temperature sensor in the energy storage system based on the second comparison result.

[0044] In some optional embodiments, when there are multiple groups of corresponding equal predicted values ​​(i.e., first temperature values) and reference temperature values ​​(i.e., second temperature values), the type of temperature sensor used in the energy storage system (or product) is determined by an iterative screening method (i.e., a first determination strategy). Specifically, a group of equal predicted values ​​(i.e., first temperature values) and reference temperature values ​​(i.e., second temperature values) are first determined, and the simulation model corresponding to the predicted value (i.e., first temperature value) and the temperature sensor corresponding to the reference temperature value (i.e., second temperature value) are determined; then a second group of equal predicted values ​​(i.e., first temperature values) and reference temperature values ​​(i.e., second temperature values) are determined, as well as the simulation model corresponding to the predicted value (i.e., first temperature value) in the second group and the temperature sensor corresponding to the reference temperature value (i.e., second temperature value) in the second group. After determining multiple groups of corresponding equal predicted values ​​(i.e., first temperature values) and reference temperature values ​​(i.e., second temperature values), corresponding multiple simulation models and multiple temperature sensors according to the above method, after the energy storage system (or product) continues to operate in a charging state or a discharging state for a preset time (such as ten minutes, thirty minutes, one hour, etc., which can be customized), obtain the predicted temperature value (i.e., third temperature value) of the energy storage system (or product) by the simulation model at the moment (i.e., second moment) after the energy storage system (or product) has operated for the preset time, and obtain multiple different temperature-sensing temperature values ​​(i.e., fourth temperature values) calculated by the BMU at the same moment (second moment) based on the relationship between the temperature-sensing temperature and the resistance value (i.e., attribute information) of multiple different temperature sensors; compare the predicted temperature values ​​(i.e., third temperature values) and the temperature-sensing temperature values ​​(i.e., fourth temperature values) of the multiple simulation models at the second moment to obtain another comparison result (i.e., second comparison result) to determine whether there are equal predicted temperature values ​​(i.e., third temperature values) and temperature-sensing temperature values ​​(i.e., fourth temperature values).

[0045] According to some other optional embodiments of the present application, the type of the temperature sensor in the energy storage system is determined according to the second comparison result, including the following method: if the second comparison result indicates that there are equal third temperature values ​​and fourth temperature values, repeatedly execute the first determination strategy until only a set of equal predicted values ​​and reference values ​​remains, and determine the type of the temperature sensor in the energy storage system as the type of the temperature sensor corresponding to the reference value, wherein the predicted value is the temperature value of the energy storage system at the next moment predicted by the simulation model, and the reference value is the temperature value of the temperature sensor at the next moment determined according to the attribute information of the temperature sensor.

[0046] In other optional embodiments, if after comparing the predicted temperature value of the simulation model at the moment after the energy storage system (or product) has run for a preset period of time and the temperature sensing temperature value calculated by BMU based on the relationship between the resistance value of the temperature sensor and the temperature sensing temperature (i.e., attribute information), there is only one set of corresponding equal predicted temperature values ​​and temperature sensing temperature values ​​of the simulation model, then the simulation model is determined to be a simulation model of an energy storage system (or product) that uses a temperature sensor of the type corresponding to the temperature sensing temperature value; otherwise, if there are still multiple sets of corresponding equal predicted temperature values ​​and temperature sensing temperature values ​​of the simulation model, the above-mentioned iterative screening steps are repeated until there is only one set of corresponding equal predicted temperature values ​​(i.e., predicted values) and temperature sensing temperature values ​​(i.e., reference values) of the simulation model.

[0047] According to an optional embodiment of the present application, determining the type of temperature sensor in the energy storage system according to the second determination strategy also includes the following method: determining that a temperature sensor in the energy storage system has failed; or, again obtaining multiple first temperature values ​​predicted by multiple simulation models at the first moment, and multiple second temperature values ​​at the same moment, and again comparing the first temperature value and the second temperature value corresponding to each temperature sensor to obtain a third comparison result; if the third comparison result indicates that the first temperature value and the second temperature value corresponding to multiple temperature sensors are equal, determining the type of temperature sensor in the energy storage system according to the first determination strategy; if the third comparison result indicates that the first temperature value and the second temperature value corresponding to no temperature sensor are equal, determining that a temperature sensor in the energy storage system has failed.

[0048] In this embodiment, when the comparison result obtained by comparing multiple predicted values ​​(i.e., the first temperature value) and multiple reference temperature values ​​(i.e., the second temperature value) is that there are no equal predicted values ​​(i.e., the first temperature value) and reference temperature values ​​(i.e., the second temperature value), the second determination strategy includes the following two methods: the first method: directly determining that the temperature sensor in the energy storage system (or product) is damaged, and issuing an alarm signal or returning a prompt message to prompt the replacement of the temperature sensor in the energy storage system (or product); the second method: re-obtaining the predicted temperature values ​​(i.e., the third temperature value) of the energy storage system (or product) by multiple simulation models at the moment, and the temperature sensing temperature of the multiple temperature sensors and the temperature sensor of the energy storage system (or product) at the same time. The plurality of temperature-sensing temperature values ​​(i.e., the fourth temperature value) obtained by calculating the relationship of the organization (i.e., the attribute information) are compared. If the result of this comparison (i.e., the third comparison result) indicates that there are corresponding equal predicted temperature values ​​(i.e., the third temperature value) and temperature-sensing temperature values ​​(i.e., the fourth temperature value), the above-mentioned iterative update method (i.e., the first determination strategy) is repeated; otherwise, if the result of this comparison (i.e., the third comparison result) still indicates that there are no corresponding equal predicted temperature values ​​(i.e., the third temperature value) and temperature-sensing temperature values ​​(i.e., the fourth temperature value), it is determined that the temperature sensor in the energy storage system (or product) is damaged, and an alarm signal is issued or a prompt message is returned to prompt the replacement of the temperature sensor in the energy storage system (or product).

[0049] It should be noted that, in actual application, it is possible to select to execute the first method or the second method in the second determination strategy in a customized manner.

[0050] According to some preferred embodiments of the present application, after determining the type of the temperature sensor in the energy storage system, the method for determining the type of the temperature sensor further includes: switching the software version running in the energy storage system to a software version corresponding to the type of the temperature sensor in the energy storage system.

[0051] In some preferred embodiments, after the type of temperature sensor used in the energy storage system (or product) is determined, if the energy storage system (or product) simultaneously downloads and runs multiple versions of software, the software version used to control the temperature sensor or related to the temperature sensor in the energy storage system (or product) is switched to the software version corresponding to the type of temperature sensor; wherein the energy storage system (or product) can send a control signal to the temperature sensor through the wiring harness connected to the temperature sensor.

[0052] Figure 3 is a structural diagram of a device for determining the type of a temperature sensor provided according to an embodiment of the present application, such as Figure 3As shown, the device includes: an acquisition module 30, used to obtain multiple first temperature values ​​predicted by multiple simulation models at a first moment, wherein the multiple simulation models are respectively established according to the initial temperatures of multiple temperature sensors set in the energy storage system, and the first moment is any moment when the energy storage system is in a charging state or a discharging state; a first determination module 32, used to determine multiple second temperature values ​​of the multiple temperature sensors at the first moment according to the attribute information corresponding to the multiple temperature sensors, wherein the attribute information is used to indicate the relationship between the temperature sensing temperature and the resistance of the temperature sensor; a comparison module 34, used to compare the first temperature value and the second temperature value corresponding to each temperature sensor respectively to obtain a first comparison result; a second determination module 36, used to determine the type of temperature sensor in the energy storage system according to the first comparison result.

[0053] Figure 4 is a flowchart of a device for determining the type of temperature sensor, such as Figure 4 As shown, before the device starts working, it first establishes a simulation model, obtains the temperature sense temperature measured by the temperature sensor in the energy storage system (or product) before the energy storage system (or product) is charged or discharged as the initial temperature, obtains the historical operation data of the energy storage system (or product) (including operation time and heat dissipation), and the relationship between the operation time and heat dissipation of the energy storage system (or product) obtained by analyzing the operation data, and establishes different simulation models corresponding to different energy storage systems (or products) based on the different initial temperatures of different energy storage systems (or products) using different types of sensors and the corresponding relationship between the operation time and heat dissipation of different energy storage systems (or products). When the device starts running, the above-established simulation model is used, as shown in FIG. Figure 4As shown, the method of using the simulation model is as follows: first, confirm whether the battery pack is in a charging or discharging state. When the battery pack is in a charging state or a discharging state, obtain the predicted temperature value of the energy storage system (or product) at the next charging or discharging moment predicted by the simulation model through the acquisition module 30; at the same time, obtain the temperature value of the temperature sensor at the next charging or discharging moment according to the relationship between the temperature value and the resistance value of different types of temperature sensors (i.e., attribute information) through the first determination module 32; next, compare the above-mentioned multiple predicted temperature values ​​with the multiple temperature values ​​through the comparison module 34, and determine the temperature value of the energy storage system (or product) used in the next charging or discharging moment through the second determination module 36. Specifically, if the comparison result output by the comparison module 34 indicates that there are multiple sets of corresponding equal predicted values ​​and temperature-sensing temperature values, iterative screening is continuously performed until only one set of corresponding equal predicted values ​​and temperature-sensing temperature values ​​remains. If the temperature sensor corresponding to the temperature-sensing temperature value is a temperature sensor of type X, the simulation model is confirmed to be a simulation model corresponding to an energy storage system (or product) using a temperature sensor of type X, i.e., it is simultaneously determined that the energy storage system (or product) being tested uses a sensor of type X. Otherwise, if the predicted values ​​and temperature-sensing temperature values ​​do not match, the temperature sensor is deemed to be damaged, or the above steps are repeated for iterative comparison.

[0054] It should be noted that Figure 3 The preferred implementation of the embodiment shown can be found in Figure 2 The relevant description of the illustrated embodiment will not be repeated here.
