[0046] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0047] Figure 1 The flowchart of the automobile battery detection method according to the embodiment of the present invention is shown, and the method is executed by an electronic device. The memory of the electronic device is used to store at least one executable instruction, and the executable instruction enables the processor of the electronic device to execute the operation of the above-mentioned automobile battery detection method.

[0048] like Figure 1As shown, the method comprises the following steps:

[0049] Step 110: Determine the cold starting current and no-load voltage of the battery to be tested.

[0050] Among them, the battery to be tested is the battery that needs to be tested. The battery to be tested can be various types of automotive batteries, for example, it can be a lead-acid automotive battery. Cold cranking current (CCA) refers to the amount of current released by the battery for 30 consecutive seconds before the voltage drops to the limit feed voltage under a specified low temperature state (usually 0°F or -17.8°). If the cold cranking current of a battery with a rated voltage of 12V is 550, it means that the battery can provide 550A of current for 30 consecutive seconds when it is fully charged and under a specified low temperature state before the voltage reaches the limit feed voltage of 7.2V. No-load voltage refers to the open circuit voltage between the positive and negative terminals of the battery when no load is connected. When the automotive battery is not faulty and fully charged, the no-load voltage and cold cranking current are high. As the depth of discharge of the automotive battery continues to increase, the no-load voltage and cold cranking current both decrease to a certain extent. Furthermore, when determining the cold starting current of the battery to be tested, the internal resistance of the battery to be tested may be determined first, and the cold starting current of the battery to be tested may be determined according to the corresponding relationship between the internal resistance and the cold starting current.

[0051] Step 120: Determine a preset mapping relationship between the cold starting current and the no-load voltage according to the battery type of the battery to be tested.

[0052] Among them, automobile batteries produced by different battery manufacturers generally have different battery types, and the manufacturing materials and manufacturing processes used in automobile batteries of different battery types are different, so the battery parameters of automobile batteries of different battery types are also different. There are often different mapping relationships between the cold starting current and no-load voltage of automobile batteries of different battery types, so the battery type of the battery to be tested can be first determined, and then the preset mapping relationship between the cold starting current and the no-load voltage can be determined according to the battery type of the battery to be tested. Further, before determining the preset mapping relationship between the cold starting current and the no-load voltage according to the battery type of the battery to be tested, the mapping relationship between the cold starting current and the no-load voltage corresponding to each battery type can be pre-generated. The following is an example of pre-generating the preset mapping relationship between the cold starting current and the no-load voltage corresponding to the battery type of the battery to be tested.

[0053] Before determining the preset mapping relationship between the cold start current and the no-load voltage according to the battery type of the battery to be tested, the remaining battery capacity of the calibration battery can be determined first. The calibration battery is a battery of the same battery type as the battery to be tested. The remaining battery capacity (RC, Reserve Capacity) is also the remaining battery power or battery reserve capacity, which is used to characterize the ability of the automotive battery to continuously supply large current. Further, when determining the remaining battery capacity of the calibration battery, the charging device can be pre-controlled to charge the calibration battery. In the process of charging the calibration battery, the no-load voltage of the calibration battery continues to increase. When the no-load voltage of the calibration battery reaches the preset full voltage, the calibration battery that reaches the preset full voltage is controlled to discharge until the no-load voltage of the calibration battery reaches the preset cut-off voltage. When the calibration battery that reaches the preset full voltage is controlled to discharge, the current discharge current can be determined, and then the calibration battery that reaches the preset full voltage is controlled to discharge at a constant current with the current discharge current. The current discharge current can be set according to actual conditions, for example, it can be set to 20A, 25A or 30A. Before controlling the calibration battery to discharge after reaching the preset full voltage, the calibration battery can be allowed to stand for a period of time in advance. The standing time of the calibration battery can be set according to actual conditions, for example, it can be set to 12 hours. Further, the charging end time after the no-load voltage of the calibration battery reaches the preset full voltage can be counted. When the charging end time reaches the preset charging end time, the calibration battery to discharge after reaching the preset full voltage is controlled. The preset charging end time is the time the calibration battery needs to stand.

[0054] It should be noted that, during the discharge of the calibration battery, the no-load voltage of the calibration battery is continuously reduced, the preset full voltage is the no-load voltage of the calibration battery in the fully charged state, and the preset cut-off voltage is the no-load voltage when the calibration battery is discharged to the point where it is not suitable to continue discharging. When the no-load voltage of the calibration battery reaches the preset cut-off voltage, continued discharge may cause damage to the calibration battery. For example, for a calibration battery with a rated voltage of 12V, the preset full voltage may be 12.4V, and the preset cut-off voltage may be 10.5V. After the no-load voltage of the calibration battery reaches the preset cut-off voltage, the voltage drop time of the no-load voltage of the calibration battery from the preset full voltage to the preset cut-off voltage can be further determined, and the voltage drop time of the no-load voltage of the calibration battery from the preset full voltage to the preset cut-off voltage is determined as the battery remaining capacity of the calibration battery. The product of the battery remaining capacity and the corresponding discharge current of the calibration battery is the battery capacity of the calibration battery, in ampere hours (AH). Furthermore, since the battery capacity of the calibrated battery remains unchanged, if the discharge current of the calibrated battery corresponding to the remaining battery capacity T is I1, the calibrated battery can be fully charged and then discharged at a constant current of I2. The voltage drop time for the corresponding no-load voltage of the calibrated battery to drop from a preset full charge voltage to a preset cut-off voltage is determined as t, and the remaining battery capacity T is verified according to T×I1=t×I2.

[0055] After determining the remaining battery capacity of the calibration battery, the unit discharge duration of the calibration battery can be determined according to the remaining battery capacity, and the unit discharge duration is the duration of each discharge process of the calibration battery. When determining the unit discharge duration of the calibration battery according to the remaining battery capacity, the current discharge parameter can be determined first, and then the ratio of the remaining battery capacity to the current discharge parameter can be determined as the unit discharge duration of the calibration battery. For example, if the remaining battery capacity of the calibration battery is T and the current discharge parameter is 10, the unit discharge duration is T / 10, and the current discharge parameter can also be set to 20, 30, etc. After determining the unit discharge duration of the calibration battery, the charging device can continue to be controlled to charge the calibration battery until the calibration battery is fully charged. When the calibration battery is in a fully charged state, the calibration battery is controlled to perform cyclic discharge at a unit discharge time until the no-load voltage of the calibration battery reaches a preset cut-off voltage, and a mapping relationship between the cold starting current and the no-load voltage of the calibration battery is collected after each discharge, and a preset mapping relationship is determined based on the mapping relationship between the cold starting current and the no-load voltage of the calibration battery after each discharge.

[0056] For example, when the calibration battery is in a fully charged state, the calibration battery is first controlled to discharge at a constant current. When the discharge time reaches the unit discharge time, the first discharge of the cyclic discharge process is completed. Then, after a period of time, the calibration battery is controlled to discharge at a constant current again. When the discharge time reaches the unit discharge time again, the second discharge of the cyclic discharge process is completed. The cyclic discharge is performed in this way until the no-load voltage of the calibration battery reaches the preset cut-off voltage. Further, when the calibration battery is controlled to perform cyclic discharge at the unit discharge time, the discharge end time of the calibration battery can be counted after the last discharge of the calibration battery ends. When the discharge end time reaches the preset voltage recovery time, the calibration battery is controlled to start the next discharge. The preset voltage recovery time is the interval time of each discharge in the cyclic discharge process. The preset voltage recovery time can be set according to actual conditions, for example, it can be set to 30 minutes.

[0057] During the cyclic discharge process of the calibration battery, the mapping relationship between the cold start current and the no-load voltage of the calibration battery is recorded after each discharge, so as to generate a preset mapping relationship between the cold start current and the no-load voltage. It is understandable that there can be multiple calibration batteries, for example, 3 to 6, and the mapping relationship between the cold start current and the no-load voltage corresponding to each calibration battery can be fitted to generate a more accurate preset mapping relationship between the cold start current and the no-load voltage. In order to improve the referenceability of the preset mapping relationship, the current discharge parameter can be further increased to reduce the unit discharge time.

[0058] Step 130: Determine a test result of the battery to be tested according to the preset mapping relationship, the cold starting current and the no-load voltage.

[0059] Among them, the actual mapping relationship between the current cold starting current and the no-load voltage can be determined according to the cold starting current and the no-load voltage of the battery to be tested, and the detection result of the battery to be tested can be determined according to the actual mapping relationship and the preset mapping relationship. For example, if the target cold starting current of the battery to be tested is determined to be 300A according to the no-load voltage of the battery to be tested and the preset mapping relationship, and the actual cold starting current of the battery to be tested is 200A, since the difference between 200A and 300A is large, it can be determined that the battery to be tested has a fault and the detection result is unqualified; if the actual cold starting current of the battery to be tested is 298A, since the difference between 298A and 300A is small, it can be determined that the battery to be tested has not a fault and the detection result is qualified. Furthermore, the battery weight and electrolyte density of the battery to be tested can also be tested, and the test results can be compared with the standard values ​​to assist in determining the detection result of the battery to be tested.

[0060] When testing a car battery, the embodiment of the present invention first determines the cold starting current and no-load voltage of the battery to be tested, then determines the preset mapping relationship between the cold starting current and the no-load voltage according to the battery type of the battery to be tested, and finally determines the test result of the battery to be tested according to the preset mapping relationship, the cold starting current and the no-load voltage. It can be seen that the embodiment of the present invention can determine the actual mapping relationship between the cold starting current and the no-load voltage based on the cold starting current and the no-load voltage of the battery to be tested, and the actual mapping relationship can be compared with the preset mapping relationship to quickly determine the test result of the battery to be tested, and the detection process takes a short time and has a high detection efficiency.
