[0033] Please refer to Figure 1 , Figure 1 A flowchart of a method for generating production files of a power management system according to an embodiment of the present application is provided. The method for generating production files of the power management system according to the embodiment of the present application is applied to an electronic device, and is executed by application software installed in the electronic device. The electronic device can be a desktop computer, a notebook computer, a tablet computer, a mobile phone, etc.

[0034] It should be noted that the application scenarios described in the following embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. A person of ordinary skill in the art can know that the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems as new application scenarios appear.

[0035] The method for generating production files of the power management system will be described in detail below.

[0036] As shown in Figure 1 , the method comprises the following steps S110-S140.

[0037] S110, acquire a battery chemistry ID in a power management system; wherein the power management system comprises a power management chip and a battery, and the power management chip is used for monitoring the battery.

[0038] Specifically, the battery chemistry ID is an identity number of the chemical characteristics of the battery, and the battery chemistry ID includes information such as chemical capacity, open-circuit voltage curve, and impedance curve. The power management chip can monitor the battery voltage, current, and temperature in real time, and through the battery chemistry ID, the battery capacity and health degree can be accurately predicted, and thus the power management system can effectively manage the battery. Since the chemical capacity, open-circuit voltage curve, and impedance curve of different models of batteries are different, the battery chemistry ID needs to be acquired in advance before generating a mass production file.

[0039] In other embodiments of the application, as shown in Figure 2 S110 includes steps S111 and S112.

[0040] S111, test the battery and acquire data information of the voltage, current, and temperature of the battery changing with time during the test;

[0041] S112, acquire the battery chemistry ID according to the data information.

[0042] Specifically, the battery is tested by charging and discharging, and at the same time, the data information of the voltage, current, and temperature of the battery changing with time during the charging and discharging test is collected in real time. Through the data information, the battery chemistry ID can be obtained.

[0043] In the process of acquiring the battery chemistry ID through the data information, the data information is usually matched with the official database of the power management chip to obtain the battery chemistry ID. The error between the battery chemistry ID obtained by this method and the actual battery chemistry ID is usually large.

[0044] In this embodiment, in order to reduce the above error, the collected data information is preferably processed to obtain information such as chemical capacity, open-circuit voltage curve, and impedance curve of the battery, and thus the customization of the battery chemistry ID is realized.

[0045] In other embodiments of the application, as shown in Figure 3 S101 and S102 are further included before step S111.

[0046] S101, acquire the storage temperature of the battery before the test;

[0047] S102, determine whether to test the battery according to the storage temperature.

[0048] In the embodiment, the battery needs to be tested at normal temperature to ensure the accuracy of the test. Therefore, before the battery is tested, the storage temperature of the battery before testing is obtained in advance, and it is determined whether the battery needs to be tested immediately by judging whether the storage temperature is normal temperature. When the storage temperature is greater or less than the normal temperature, the battery needs to be placed in a normal temperature environment for a period of time before the charge and discharge test can be performed; if the storage temperature is normal temperature, the battery can be directly tested for charge and discharge.

[0049] In other embodiments of the application, as shown in Figure 4 Step S111 includes steps S1111, S1112, S1113 and S1114.

[0050] S1111, charging the battery until the battery reaches a first target state of charge;

[0051] S1112, resting the battery for a preset first time;

[0052] S1113, discharging the rested battery until the battery reaches a first target voltage;

[0053] S1114, resting the battery again for a preset second time to complete the test of the battery.

[0054] In the embodiment, the battery is tested by charging in advance to make the state of charge (SOC) of the battery reach a first target state of charge, and then the battery is rested for a period of time, that is, it is rested for a preset first time. After the resting is completed, the battery is tested by discharging until the voltage of the battery reaches a first target voltage. After the voltage of the battery reaches the first target voltage, the battery needs to be rested again for a period of time, that is, the battery is rested for a preset second time, and then the charge and discharge test of the battery is completed.

[0055] The first target state of charge can be the state of charge when the battery is fully charged, or a pre-set state of charge. The pre-set state of charge can be determined by the current during the charging process, such as 0.01C. It should be noted that the specific method of setting the first target state of charge can be selected according to actual application. The first target state of charge is preferably 100%, the first target voltage is preferably 3.0V, the preset first time is preferably 2h, and the preset second time is preferably 5h.

[0056] In other embodiments of the application, as shown in Figure 5 Step S1111 includes steps S111a and S111b.

[0057] S111a, constant current charging is performed on the battery until the battery reaches a second target voltage;

[0058] S111b, constant voltage charging is performed on the battery based on the target voltage until the battery reaches a first target state of charge.

[0059] In this embodiment, the charging test of the battery can include two stages of constant current charging and constant voltage charging. The battery can be charged at a current intensity of 0.2C until the voltage of the battery reaches the second target voltage. After completing the constant current charging, the battery can be charged at the second target voltage in the form of constant voltage charging. During the constant voltage charging, the charging current of the battery gradually decreases, and the state of charge of the battery increases until the first target state of charge is reached, and then the charging test of the battery is ended.

[0060] S120, constructing a battery model according to the battery chemical ID.

[0061] Specifically, the battery model is a simulation model of a battery pack formed by a plurality of same model batteries in series and parallel, which is used to describe the external characteristics of the battery operation, and can reflect the dynamic and static characteristics of the battery pack. The parameters of the battery model constructed by the application include battery chemical capacity, open circuit voltage curve, impedance curve and other parameter information. After obtaining the battery chemical ID, the corresponding model of the battery can be constructed according to the battery chemical ID.

[0062] S130, parameter configuration is performed on the power management chip, and the power management chip is calibrated to obtain a calibrated power management chip.

[0063] Specifically, by performing parameter configuration on the power management chip, the accuracy of the power management chip in monitoring the battery can be improved. After completing the parameter configuration, the power management chip needs to be calibrated so that the power management chip can accurately collect the voltage, current and temperature of the battery. Among them, the voltage calibration of the power management chip needs to be performed under the condition of stable voltage and no load; the current calibration of the power management chip needs to be performed under the condition of no load calibration and load calibration. The no load calibration is also called zero current calibration, which is the calibration under the condition of no load and no current. The load calibration is generally calibration under the condition of 1A or 2A. The temperature calibration of the power management chip is usually performed under the condition of stable temperature. The model of the power management chip can be BQ27542-G1, BQ27Z561-R2, BQ27742-G1, BQ28Z610-R1, BQ40Z50-R3, etc. The model of the power management chip mentioned in the application is preferably BQ40Z50-R3.

[0064] In other embodiments of the application, as Figure 6As shown, step S130 includes steps S131 and S132.

[0065] S131, obtaining parameter information of the power management chip;

[0066] S132, burning the power management chip, and performing parameter configuration on the power management chip according to the parameter information, to obtain the parameter-configured power management chip.

[0067] In the embodiment, the parameter information is data information obtained by modifying the basic parameter information of the power management chip. The parameter information can be obtained by modifying the basic parameter information of the power management chip in advance. After obtaining the parameter information of the power management chip, the power management chip can be burned by using the basic parameter information of the power management chip, and then the power management chip can be modified according to the parameter information, so as to realize the parameter configuration of the power management chip. In the parameter modification of the power management chip by using the parameter information, some registers in the power management chip which are defined more complex and irrelevant to the protection board in the power management system are closed, and the register bits of the protection bits in the power management chip are opened as much as possible. The registers of over-charge capacity and the registers of low-temperature protection can be selected to be closed or opened according to whether there is a discharge at-40℃.

[0068] S140, performing charge-discharge cycle on the battery, and updating the battery model according to the calibrated power management chip, to generate the production file of the power management system.

[0069] Specifically, the battery chemical ID mentioned in the present application includes open-circuit voltage curve, maximum chemical capacity, impedance curve and other information, and the battery chemical ID is based on a new single battery. When the battery is assembled into a battery pack, the capacity and impedance of the battery pack are easily different from the recorded data of the ID due to the factors such as the number of parallel-connected batteries, the protection board and the individual difference of the battery cells. Therefore, it is necessary to perform charge-discharge cycle on the battery, and update the battery model by using the calibrated power management chip, so that the power management chip can more accurately monitor the battery. After updating the battery model by using the calibrated power management chip, the production file of the power management system can be generated according to the corresponding updated data, so as to realize the batch production of the battery.

[0070] Specifically, each charge-discharge cycle of the battery includes: emptying the battery, then standing for more than 5 hours, then charging the battery to make the state of charge of the battery reach 100%, and standing again for more than 5 hours, then emptying the battery again, standing and charging, so as to realize the charge-discharge cycle of the battery.

[0071] In addition, in order to ensure the health degree of the battery, the number of charge-discharge cycles of the battery is preferably 3-4 charge-discharge cycles.

[0072] In other embodiments, as shown in FIG. 1, step S140 includes steps S141 and S142. Figure 7

[0073] S141, generating the open-circuit voltage curve, the maximum chemical capacity and the impedance curve of the battery in the charge-discharge cycle of the battery according to the calibrated power management chip;

[0074] S142, updating the battery model according to the open-circuit voltage curve, the maximum chemical capacity and the impedance curve.

[0075] In this embodiment, the calibrated power management chip can obtain the open-circuit voltage, the maximum chemical capacity and the impedance of the battery at each moment by collecting the voltage, current and temperature of the battery in real time and then performing corresponding calculation, and then the open-circuit voltage curve, the maximum chemical capacity and the impedance curve of the battery in the charge-discharge cycle of the battery can be obtained, so that the parameter updating of the battery model can be realized.
