Abstract

[0002] In the battery system, the battery pack is the main component. The battery pack is composed of multiple battery modules, each battery module is composed of multiple battery cells, and the battery modules or battery cells are connected by conductive connectors. Common conductive connectors include copper busbars (also known as copper busbars or copper busbars), aluminum busbars, etc., which are used to transmit current. When the battery system is controlled to discharge the battery pack at high power, the current on the conductive connector increases, and the temperature will also rise accordingly. The resistivity and resistance of the conductive connector increase, and the temperature rise phenomenon is further aggravated.

[0035] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0036] Reference Figure 1 , shows a flow chart of a data processing method based on a conductive connector provided by an embodiment of the present invention, which may specifically include the following steps:
[0037] Step 101, in response to the need to determine the target temperature value of the conductive connecting component, obtain a temperature drop characteristic parameter value and a temperature rise characteristic parameter value of the conductive connecting component; wherein the temperature drop characteristic parameter value represents a mapping relationship between the temperature value of the conductive connecting component changing with time when it decreases, and the temperature rise characteristic parameter value represents a mapping relationship between the temperature value of the conductive connecting component changing with time when it increases;
[0038] In this embodiment, the conductive connector may be a conductive connector in a battery pack, and specifically may be a copper busbar, an aluminum busbar, or other components.
[0039] The cooling characteristic parameter value represents the mapping relationship of the temperature value of the conductive connector changing with time when it decreases, that is, the cooling characteristic parameter value can reflect a certain law of cooling of the conductive connector in a natural state. After determining the temperature value of the conductive connector at a certain moment, the temperature value of the conductive connector after cooling down at the next moment can be predicted through the cooling characteristic parameter value; similarly, the heating characteristic parameter value represents the mapping relationship of the temperature value of the conductive connector changing with time when it increases. After determining the temperature value of the conductive connector at a certain moment, the temperature value of the conductive connector after heating up at the next moment can be predicted through the heating characteristic parameter value.
[0040] In the specific implementation, the cooling characteristic parameter value and the heating characteristic parameter value are mainly related to the specific design of the conductive connector, such as the material and shape design used. The cooling characteristic and the heating characteristic of the conductive connector are not easy to change. Therefore, the cooling characteristic parameter value and the heating characteristic parameter value can be fixed values, which can be obtained by experimentally testing the conductive connector, and the cooling characteristic parameter value and the heating characteristic parameter value obtained by the experimental test are saved in storage media such as flash memory and hard disk for use.
[0041] In some embodiments of the present invention, the method for determining the cooling characteristic parameter value includes:
[0042] In the process of producing the conductive connecting member, detecting a plurality of first temperature values of the conductive connecting member and a plurality of second ambient temperature values of the environment where the conductive connecting member is located during the cooling process of the conductive connecting member; wherein each first temperature value and each second ambient temperature value corresponds to a first time value;
[0043] The temperature reduction characteristic parameter value is determined according to the first time value, the first temperature value and the second ambient temperature value.
[0044] In a specific implementation, the temperature reduction characteristic parameter value can be determined through experimental testing during the production stage before the conductive connector is put into practical use.
[0045] As an example, during the test, the use scenario of the conductive connector under high power can be simulated, such as the scenario of the battery pack being discharged at high power, and the conductive connector is first energized to increase its temperature, and then the power is removed to allow it to cool down naturally. At this time, the temperature of the conductive connector is higher than the ambient temperature (such as the ambient temperature of the laboratory), and the conductive connector mainly relies on air convection to dissipate heat.
[0046] Furthermore, from the moment when the conductive connector starts to cool down after the power is removed to the moment when the temperature of the conductive connector drops to the specified temperature value, during this cooling process, the first temperature value of the conductive connector and the second ambient temperature value of the environment where the conductive connector is located are detected once every unit time, and multiple first temperature values and multiple second ambient temperature values are obtained, and the corresponding first time value is recorded. For example, assuming that the unit time is seconds, the first time value at the start of detection is 0 seconds, and the first time value at the end of detection is 300 seconds, and detection is performed once per second, 301 sets of data of the first temperature value, the second ambient temperature value, and the first time value can be obtained.
[0047] Furthermore, after obtaining multiple sets of experimental data, the cooling characteristic parameter values can be determined through data analysis, machine learning, etc., for example, by inputting the experimental data into a pre-trained model, or processing the experimental data through a preset algorithm.
[0048] In some embodiments of the present invention, determining the cooling characteristic parameter value according to the first time value, the first temperature value and the second ambient temperature value includes:
[0049] Determine a functional relationship between a difference between the first temperature value and the second ambient temperature value and the first time value; wherein the functional relationship includes a cooling characteristic parameter;
[0050] According to the functional relationship, a fitting process is performed on the first temperature value, the second ambient temperature value, and the first time value to determine a cooling characteristic parameter value corresponding to the cooling characteristic parameter.
[0051] In a specific implementation, the functional relationship between the difference between the first temperature value and the second ambient temperature value and the first time value can be determined as the following formula (1):
[0052]
[0053] Wherein, k1 is a temperature reduction characteristic parameter, T is a first temperature value, Te is a second ambient temperature value, and t is a first time value corresponding to the first temperature value and the second ambient temperature value.
[0054] Furthermore, according to the functional relationship between the first temperature value and the first time value in formula (1), all the first temperature values, the second ambient temperature values, and the first time values are fitted, and the cooling characteristic parameter k1 is solved to obtain the cooling characteristic parameter value corresponding to the temperature characteristic parameter.
[0055] In some embodiments of the present invention, the functional relationship includes an exponential functional relationship, and the fitting process includes a curve fitting process.
[0056] In a specific implementation, if the first temperature value, the second ambient temperature value, and the first time value satisfy an exponential function relationship as shown in formula (1), curve fitting processing can be performed on the first temperature value, the second ambient temperature value, and the first time value according to the exponential function relationship to solve the cooling characteristic parameter in formula (1) to obtain the cooling characteristic parameter value.
[0057] As an example, the first temperature value, the second ambient temperature value, and the first time value can be subjected to curve fitting processing through the np.polyfit(x,y,n) function in the Python language. All first time values are input as independent variable data points (i.e., parameter x in np.polyfit(x,y,n)). The first temperature value is T, and the second ambient temperature value is Te. The first temperature value and the second ambient temperature value corresponding to each first time value are subjected to the ln(T-Te) operation and then input as dependent variable data points (i.e., parameter y in np.polyfit(x,y,n)). Then, a first-order curve fitting is performed, and 1 is input as parameter n in np.polyfit(x,y,n). The value of parameter k1 in formula (1), i.e., the cooling characteristic parameter value, can be obtained. The curve generated after curve fitting processing is as follows: Figure 2 As shown. Figure 2 In the figure, the ordinate represents the first temperature value, in degrees Celsius; the abscissa represents the first time value, in seconds.
[0058] In some embodiments of the present invention, the method for determining the temperature rise characteristic parameter value includes:
[0059] In the process of producing the conductive connecting member, the conductive connecting member is energized with a preset current value so that the temperature value of the conductive connecting member increases from an initial temperature value to a preset temperature threshold value;
[0060] In the process of the temperature value of the conductive connecting member rising from the initial temperature value to the preset temperature threshold, detecting a plurality of second temperature values of the conductive connecting member and a plurality of third ambient temperature values of the environment where the conductive connecting member is located; wherein each second temperature value and third ambient temperature value corresponds to a second time value;
[0061] The temperature reduction characteristic parameter value is obtained, and the temperature increase characteristic parameter value is determined according to the preset current value, the second time value, the second temperature value, the third ambient temperature value, and the temperature reduction characteristic parameter value.
[0062] In a specific implementation, the temperature rise characteristic parameter value can be determined through experimental testing during the production stage before the conductive connector is put into practical use.
[0063] As an example, when the temperature value of the conductive connection is close to the temperature value of the environment in which it is located, a preset current value is used to energize it to simulate the temperature rise during operation.
[0064] When power is first supplied, the conductive connector has an initial temperature value, and power is stopped when the temperature value of the conductive connector reaches a preset temperature threshold. During this heating process, the second temperature value of the conductive connector and the third ambient temperature value of the environment in which the conductive connector is located are detected once per unit time, and multiple second temperature values and multiple third ambient temperature values are obtained, and the corresponding second time values are recorded, thereby obtaining multiple sets of experimental data.
[0065] Furthermore, after obtaining multiple sets of experimental data, the temperature rise characteristic parameter values can be determined through data analysis, machine learning, etc., for example, by inputting the experimental data into a pre-trained model, or processing the experimental data through a preset algorithm.
[0066] Specifically, the preset current value, the cooling characteristic parameter value, the second temperature value, the third ambient temperature value, the second time value, and the functional relationship satisfying the following formula (2) are assumed:
[0067]
[0068] Wherein, k2 is the temperature rise characteristic parameter, I is the preset current value, T is the second temperature value, Te is the third ambient temperature value, t is the second time value, and k1 is the temperature drop characteristic parameter value; It can be obtained by dividing the difference between the second temperature value at the current moment and the second temperature value at the previous moment by the difference between the current moment and the previous moment. For example, if the second time value at the current moment is the 10th second, the corresponding second temperature value is 25°C, and the second time value at the previous moment is the 9th second, the corresponding second temperature value is 23, then
[0069] Thus, for each t, I, T, Te, If they are all known values, k2 can be solved to get the value of k2 corresponding to each t, and then the value of k2 corresponding to each t can be averaged to determine the temperature rise characteristic parameter value.
[0070] In some embodiments of the present invention, the preset current value is determined according to a maximum current value allowed to pass through the conductive connecting member.
[0071] In a specific implementation, assuming that the maximum current value allowed to pass through the conductive connector is Imax, the preset current value may be any current value less than or equal to Imax, such as a current value that is a certain proportion of Imax.
[0072] In some embodiments of the present invention, the method for determining the temperature rise characteristic parameter value further includes:
[0073] Determining a plurality of different preset current values, and determining a plurality of initial temperature rise characteristic parameter values based on the plurality of different preset current values;
[0074] An average value of the plurality of initial temperature rise characteristic parameter values is determined as the temperature rise characteristic parameter value.
[0075] In a specific implementation, different preset current values may be used to perform multiple tests on the temperature rise characteristic parameter values to obtain multiple initial temperature rise characteristic parameter values. As an example, assuming that the number of tests is N, and the maximum current value allowed to pass through the conductive connector is Imax, then the different preset current values may be i / N*Imax, where i is a positive integer from 1 to N.
[0076] Furthermore, different preset currents are used for measurement to obtain different initial temperature rise characteristic parameter values, and all initial temperature rise characteristic parameter values are averaged to determine the temperature rise characteristic parameter value. For example, for N tests, a total of N initial temperature rise characteristic parameter values are obtained, and the average value obtained by summing the N initial temperature rise characteristic parameter values and dividing by N can be determined as the temperature rise characteristic parameter value.
[0077] Step 102, detecting a first current value of the conductive connecting member, and detecting a first ambient temperature value of an environment where the conductive connecting member is located;
[0078] In a specific implementation, the first current value may be a real-time current value of the conductive connector at the current moment, and the first ambient temperature value may be a real-time ambient temperature value of the environment where the conductive connector is located at the current moment.
[0079] Step 103 : determining the target temperature value according to the first current value, the first ambient temperature value, the temperature reduction characteristic parameter value, and the temperature increase characteristic parameter value.
[0080] In a specific implementation, the target temperature value can be determined by the following formula (3):
[0081] T i+1 =T i +k2*I 2 +k1*(T i -Te) (3)
[0082] Among them, T i+1 That is the target temperature value of the conductive connection at the next moment, T i is the temperature value of the conductive connector at the current moment. When the conductive connector starts working, the first ambient temperature value can be used as the initial T i ; k2 is the temperature rise characteristic parameter value, I is the first current value, and k1 is the temperature drop characteristic parameter value.
[0083] In this way, the target temperature value at any moment in the operation of the conductive connector can be determined. In practical applications, the battery system can be controlled based on the target temperature value, for example, the discharge power of the battery pack can be controlled. When it is determined by the above method that the target temperature value of the conductive connector is too high, the discharge power of the battery pack is reduced to achieve intelligent dynamic regulation of the discharge power of the battery pack without the need to use sensors to monitor the temperature value of the conductive connector in real time.
[0084] It should be noted that, for the sake of simplicity, the method embodiments are described as a series of action combinations, but those skilled in the art should be aware that the embodiments of the present invention are not limited by the order of the actions described, because according to the embodiments of the present invention, certain steps can be performed in other orders or simultaneously.
