Description

Technical Field

[0001] The present invention relates to the field of intelligent control technology, and particularly to a battery state warning control circuit and an electronic device applied to a battery clip. Background Art

[0002] Battery clips are usually used for temporarily connecting batteries, such as jump-starting a car, connecting external devices, etc., so that the battery can communicate with external devices, and then the application object corresponding to the battery can operate normally.

[0003] In the prior art, for the detection, warning and control of the battery state, it is usually realized by using a battery management system (BMS). However, for a battery clip, its design initially focuses more on the convenience and immediacy of the application, and it does not have the attribute of a BMS system itself.

The following will be described in detail respectively.

[0076] Embodiment 1

[0077] Please refer to Figure 1 , Figure 1 , which is a schematic structural diagram of a battery status warning control circuit applied to a battery clip disclosed in an embodiment of the present invention. Among them, Figure 1 The described battery status warning control circuit applied to a battery clip can be applied to battery clips, vehicles, other battery application devices, etc., and can also be applied to vehicle inspection / repair equipment, including but not limited to test clips, and can also be applied to intelligent devices having a connection relationship with the above devices. The intelligent devices include but are not limited to one or more of cloud devices, edge computing devices, intelligent networked devices, smart home devices, and urban management devices. The embodiments of the present invention do not make limitations. As Figure 1 shown, the circuit includes a detection module 10 and a control module 20, where:

[0078] The first end of the detection module 10 is electrically connected to the first end of the control module 20. The second end of the detection module 10 and the second end of the control module 20 are used to be electrically connected to the battery. The third end of the control module 20 is used to be electrically connected to the emergency start power supply. The fourth end of the control module 20 is used to be electrically connected to the target object corresponding to the battery;

[0079] The detection module 10 is used to convert the detected electrical signal parameters of the battery into detection feedback parameters;

[0080] The control module 20 is used to generate a module control parameter for the detection module 10 according to the detection feedback parameter. The module control parameter is used to control the detection module 10 to adjust its own first state parameter based on the electrical signal parameter, so that the control module 20 detects the feedback control parameter in the detection module 10, and the feedback control parameter is generated based on the first state parameter;

[0081] The control module 20 is further used to generate a detection warning parameter of the battery according to the feedback control parameter. The detection warning parameter is used to indicate the health status of the battery to the target object corresponding to the battery;

[0082] The control module 20 is further used to judge whether the battery meets the preset emergency control condition according to the obtained electrical state parameter of the emergency start power supply and the detection feedback parameter;

[0083] The control module 20 is further used to, when it is judged that the battery meets the preset emergency control condition, generate an emergency control parameter according to the electrical state parameter and the detection feedback parameter. The emergency control parameter is used to perform a corresponding emergency control operation on the battery, and the emergency control operation is an emergency power supply operation or a power-off protection operation.

[0084] In an embodiment of the present invention, optionally, the above detection module has positive and negative electrodes. The positive electrode is connected to the positive electrode of the battery, and the negative electrode is connected to the negative electrode of the battery. The battery type parameter, the rated cold start current parameter of the battery, and other battery parameters can be sent to the above control module at any time through the mobile terminal device and the wireless communication device. The control module can calculate and generate the above emergency control conditions based on the above battery parameters. At the same time, the above detection warning parameters of the battery can also be generated in combination with the above feedback control parameters.

[0085] Further optionally, the above target object can represent the above mobile terminal device, and can also represent the unit, department, etc. corresponding to the above mobile terminal device. The embodiments of the present invention do not make specific limitations in this regard.

[0086] Furthermore, it should be noted that the first end, the second end, etc. described in the embodiments of the present invention do not mean that each end only includes one branch / lead. It can be multiple branches / leads, as long as it does not affect the function description of each module / unit, and there is no contradiction in the connection relationship between the modules / units.

[0087] It can be seen that implementing the embodiments of the present invention can generate module control parameters for the detection module based on the detection feedback parameters converted by the detection module by the control module, so that the control module controls the detection module to adjust the first state parameter of the detection module itself based on the electrical signal parameters. Furthermore, the control module detects the feedback control parameters in the detection module, and the control module generates detection warning parameters for the battery to indicate the health status of the battery to the target object corresponding to the battery based on the feedback control parameters, so that the battery clip improves the accuracy and timeliness of the battery status warning by changing the first state parameter of its own detection module, improves the intelligence level of the battery clip, and further enables the target object corresponding to the battery to know the health status of the battery in a timely and accurate manner without relying on the power management system. At the same time, the control module also judges whether the battery meets the preset emergency control conditions according to the obtained electrical state parameters of the emergency start power supply and the detection feedback parameters; and when the judgment result is yes, according to the electrical state parameters and the detection feedback parameters, an emergency control operation for performing a corresponding emergency power supply operation or power-off protection operation on the battery is generated. On the basis of improving the emergency power supply control of the battery, it can further ensure the healthy emergency control of the battery, trigger the power-off protection mechanism in time, so as to improve the comprehensiveness and accuracy of the battery emergency control, which is beneficial to ensuring the service life of the battery and improving the application safety of the battery and the application safety of the battery clip.

[0088] In an embodiment of the present invention, as an optional implementation manner, the above electrical signal parameters include a first electrical signal sub-parameter and a second electrical signal sub-parameter, such as Figure 2 shown Figure 2A structural schematic diagram of a detection module is disclosed. The above detection module 10 includes a detection sub-module 101, a first control sub-module 102, an acting sub-module 103, and a first feedback sub-module 104, where:

[0089] The first end of the detection sub-module 101 is electrically connected to the first end of the control module 20. The second end of the detection sub-module 101 is used to be electrically connected to the battery. The first end of the first control sub-module 102 is electrically connected to the first end of the control module 20. The second end of the first control sub-module 102 is electrically connected to the first end of the acting sub-module 103. The second end of the acting sub-module 103 is used to be electrically connected to the battery. The third end of the acting sub-module 103 is electrically connected to the first end of the first feedback sub-module 104. The second end of the first feedback sub-module 104 is electrically connected to the first end of the control module 20. The third end of the first feedback sub-module 104 is used to be electrically connected to the battery;

[0090] The detection sub-module 101 is used to convert the detected electrical signal parameters of the battery into detection feedback parameters;

[0091] The first control sub-module 102 is used to adjust the second state parameter of the first control sub-module 102 itself according to the module control parameter, so that the acting sub-module 103 adjusts the third state parameter of the acting sub-module 103 itself based on the first electrical signal sub-parameter;

[0092] The first feedback sub-module 104 is used to generate a feedback control parameter according to the third state parameter and the second electrical signal sub-parameter, so that the control module 20 detects the feedback control parameter.

[0093] In the embodiments of the present invention, it should be noted that the above first state parameter cannot be regarded as the sum / stack of the second state parameter and the third state parameter. It can only be explained that since the first control sub-module adjusts its own second state parameter based on the module control parameter, so that the acting sub-module adjusts the third state parameter of the acting sub-module itself based on the first electrical signal sub-parameter, only then does the more upper-level module of the detection module show that it has adjusted its own first state parameter. In this process, the state parameter change effect brought by the detection module itself may be more obvious or more attenuated. The embodiments of the present invention do not make specific limitations on this, but it is clearly limited that the functions of the above parameters and the relationship between adjusting their own state parameters, and the associated relationship brought by the specific state parameters are also related to the changes of the internal components of the above modules. There is an embodiment below that can specifically illustrate the above phenomenon, but in the embodiments of the present invention, the above first state parameter cannot be regarded as the sum / stack of the second state parameter and the third state parameter.

[0094] It can be seen that implementing this optional embodiment can further divide the detection module into a detection sub-module, a first control sub-module, an action sub-module, and a first feedback sub-module. Specifically, the detection sub-module converts the detected electrical signal parameters of the battery into detection feedback parameters. The first control sub-module adjusts its own second state parameters according to the module control parameters, so that the action sub-module adjusts its own third state parameters based on the first electrical signal sub-parameters. Finally, the first feedback sub-module generates feedback control parameters based on the third state parameters and the second electrical signal sub-parameters, so that the control module detects the feedback control parameters, improving the generation accuracy and feasibility of the feedback control parameters, facilitating improving the accuracy and timeliness of the battery state warning of the battery clip, enhancing the intelligence level of the battery clip, and further enabling the target object corresponding to the battery to timely and accurately know the health status of the battery without relying on the power management system.

[0097] The second feedback sub-module 1041 is used to generate a first feedback control sub-parameter according to the third state parameter;

[0098] The third feedback sub-module 1042 is used to perform a filtering and amplification processing operation on the second electrical signal sub-parameter to obtain a target sub-component parameter of the second electrical signal sub-parameter, and the target sub-component parameter is the second feedback control sub-parameter.

[0099] It can be seen that in this alternative embodiment, the first feedback sub-module is further divided into a second feedback sub-module and a third feedback sub-module. The second feedback sub-module generates a first feedback control sub-parameter according to the above-mentioned third state parameter, and the third feedback sub-module performs a filtering and amplification operation on the second electrical signal sub-parameter to obtain the target component sub-parameter of the second electrical signal sub-parameter, where the target component sub-parameter is the second feedback control sub-parameter. This improves the richness of the feedback control parameters, facilitating the control module to better generate, based on the feedback control parameters, detection and warning parameters for the battery to indicate the health status of the battery to the corresponding target object of the battery, improving the accuracy and timeliness of the battery status warning of the battery clip and enhancing the intelligence level of the battery clip.

[0100] In this alternative embodiment, as another alternative implementation, the above-mentioned detection sub-module 101 includes a first detection sub-circuit 1011 and a second detection sub-circuit 1012.

The second end of the second resistor R2, the second end of the first capacitor C1, and the second end of the first diode D1 are used to be grounded;

[0103] The second detection sub-circuit 1012 includes a third resistor R3, a fourth resistor R4, a second capacitor C2, and a second diode D2, where:

[0104] The first end of the third resistor R3 is used to be electrically connected to the battery, and the second end of the third resistor R3 is electrically connected to the first end of the fourth resistor R4, the first end of the second capacitor C2, the first end of the second diode D2, and the first end of the control module 20. The second end of the fourth resistor R4, the second end of the second capacitor C2, and the second end of the second diode D2 are used to be grounded.

[0105] In this alternative embodiment, as Figure 4 、 Figure 5As shown, the control module obtains the voltages of power+ and BAT+ in the battery through the GET_VOT1 and GET_VOT2 pins in the figure respectively. The parameters output by the GET_VOT1 and GET_VOT2 pins are detection feedback parameters.

Specifically, it includes a first detection sub-circuit and a second detection sub-circuit. Through the above structure, the detection accuracy, comprehensiveness, and feasibility of the detection feedback parameters can be further improved, which is beneficial to improving the accuracy of battery status warning analysis and control of the battery clip.

[0111] In the embodiments of the present invention, it should be noted that the number and resistance value of the above-mentioned resistors included in the above-mentioned acting sub-module can be increased in combination with the actual application scenario. In the embodiments of the present invention, only one composition method is shown. For the resistance effect in the acting sub-module, it can also be achieved by limiting the respective different parameters of the seventh resistor R7, the eighth resistor R8, the ninth resistor R9, and the third diode D3. The embodiments of the present invention do not make specific limitations on this.

[0112] In the embodiments of the present invention, the above-mentioned module control parameters are generated through the CTR_TEST pin. The first MOS transistor Q1 is turned on or off under the control of the module control parameters of CTR_TEST, so that the second state parameter of the first control sub-module itself is adjusted. When the first MOS transistor Q1 is turned on or off, the first electrical signal sub-parameter passes through POWER+, prompting the first electrical signal sub-parameter to conduct or not conduct through the seventh resistor R7, the eighth resistor R8, the ninth resistor R9, and the third diode D3 in the above-mentioned acting sub-module. During this process, the third state parameter of the acting sub-module itself is adjusted.

[0113] It can be seen that implementing this optional embodiment discloses a specific structure of the first control sub-module and the acting sub-module. Through the above structure, the accuracy, comprehensiveness, and feasibility of generating feedback control parameters can be further improved, which is beneficial to further improving the accuracy of battery state warning analysis and control of the battery clip.

[0116] And, optionally, as Figure 9 shown, Figure 9 a structural schematic diagram of a third feedback sub-module is disclosed. As Figure 9 shown, the third feedback sub-module 1042 includes a filtering unit 10421, an amplifying unit 10422, and a converting unit 10423, where:

[0121] In an embodiment of the present invention, optionally, the above-mentioned filtering unit may be a capacitor, and other components may be additionally provided on this basis to further improve the functional effect of the filtering unit. Further optionally, the above-mentioned amplifying unit may include specific amplifying components and their supporting amplifying circuits. Among them, optionally, the above-mentioned amplifying component may be MCP6004, and the corresponding supporting amplifying circuit may be adaptively adjusted in combination with the specific expected amplification factor and the scale of the application scenario. The embodiments of the present invention do not make specific limitations on this.

[0122] Further optionally, for the above-mentioned converting unit, according to the actual application scenario requirements, resistors and capacitors with different resistance values and capacitance values are added and obtained by parallel connection. Further, the above-mentioned filtering unit, amplifying unit and converting unit may be integrated in the same chip device, specifically subject to the actual application scenario.

[0123] It can be seen that implementing this optional embodiment can handle the voltage fluctuations existing between the BAT+ pin and the BAT- pin of the battery due to load discharge during the generation of the above-mentioned first feedback control sub-parameter. The above-mentioned filtering unit can filter out the DC component to obtain the fluctuating AC component, the AC component is amplified by the amplifying unit according to the preset amplification, and then the target component sub-parameter is calculated by the converting unit to obtain the second feedback control sub-parameter, which can further improve the generation accuracy, comprehensiveness and feasibility of the second feedback control sub-parameter, and is beneficial to further improving the accuracy of the battery state early warning analysis and control of the battery clip.

[0124] In an optional embodiment, as Figure 10 shown Figure 10A structural schematic diagram of a control module is disclosed. The above-mentioned control module 20 includes a first parameter generation control unit 201, a first state analysis control unit 202, a second parameter generation control unit 203, and a second state analysis control unit 204, where:

[0125] The first end of the first parameter generation control unit 201 is electrically connected to the first end of the detection module 10. The second end of the first parameter generation control unit 201 is electrically connected to the first end of the first state analysis control unit 202. The third end of the first parameter generation control unit 201 is used to be electrically connected to the target object corresponding to the battery. The first end of the second state analysis control unit 204 is electrically connected to the first end of the detection module 10. The second end of the second state analysis control unit 204 is used to be electrically connected to the emergency start power supply. The third end of the second state analysis control unit 204 is electrically connected to the first end of the second parameter generation control unit 203. The second end of the second parameter generation control unit 203 is used to be electrically connected to the battery. The third end of the second parameter generation control unit 203 is used to be electrically connected to the emergency start power supply;

[0126] The first parameter generation control unit 201 is used to generate module control parameters for the detection module 10 according to the detection feedback parameters;

[0127] The first state analysis control unit 202 is used to calculate the first capacity state parameter and the first internal resistance state parameter of the battery according to the feedback control parameters;

[0128] The first state analysis control unit 202 is further used to match the second internal resistance state parameter of the battery according to the feedback control parameters and the first capacity state parameter;

[0129] The first state analysis control unit 202 is further used to determine whether the first internal resistance state parameter is within the preset parameter range of the second internal resistance state parameter to obtain a judgment result;

[0130] The first parameter generation control unit 201 is further used to generate detection warning parameters for the battery according to the judgment result. The detection warning parameters are used to indicate the health status of the battery to the target object corresponding to the battery;

[0131] The second state analysis control unit 204 is used to determine whether the battery meets the preset emergency control conditions according to the obtained electrical state parameters of the emergency start power supply and the detection feedback parameters;

[0132] The second parameter generation control unit 203 is used to generate emergency control parameters according to the electrical state parameters and the detection feedback parameters when the second state analysis control unit 204 determines that the battery meets the preset emergency control conditions. The emergency control parameters are used to perform corresponding emergency control operations on the battery. The emergency control operation is an emergency power supply operation or a power-off protection operation.

[0133] In an embodiment of the present invention, optionally, the specific method for calculating the first internal resistance state parameter may be:

[0134] R_internal1 = (VGET_D0 / N) / (VGET_D2 / Rload);

[0135] Wherein, R_internal1 is the first internal resistance state parameter, VGET_D0 corresponds to the second feedback control sub-parameter described above, N corresponds to a preset amplification factor, VGET_D2 corresponds to the first feedback control sub-parameter, and Rload corresponds to the load value parameter of the acting sub-module under the third state parameter;

[0136] For "judging whether the first internal resistance state parameter is within the preset parameter range of the second internal resistance state parameter to obtain a judgment result", for example, if the first internal resistance state parameter of a certain 12V, 120AH battery is calculated to be 8MΩ; but the matched first internal resistance state parameter is 4.5, then it can be judged that the battery needs to be replaced. Further, for the judgment result, the health state of the battery corresponding to the above can be analyzed by combining the position of the first internal resistance state parameter within the preset parameter range of the second internal resistance state parameter. For the above target object, it can be one or more of the terminal device, unit, family member, etc. corresponding to the battery user;

[0137] In an embodiment of the present invention, further optionally, the above-mentioned judging whether the battery meets the preset emergency control condition according to the obtained power state parameter and detection feedback parameter of the emergency starting power supply may be specifically: judging whether the power state parameter of the emergency starting power supply is greater than or equal to a preset first voltage threshold, and whether the comparison value between the corresponding power + pin and the preset second voltage threshold in the detection feedback parameter is greater than or equal to a preset third voltage threshold. If so, it is determined whether the battery meets the preset emergency control condition;

[0138] Further optionally, the above-mentioned determining whether the battery meets the preset emergency control condition can also be achieved by setting a conduction period for the relay, for example, conducting once every 100ms for a conduction time of 3s, which can be specifically adjusted according to the actual application scenario.

[0139] It can be seen that implementing this optional embodiment can further divide the control module into a first parameter generation control unit, a first state analysis control unit, a second parameter generation control unit, and a second state analysis control unit. Thus, the refined control module further determines whether the battery meets the preset emergency control conditions based on the obtained electrical state parameters and detection feedback parameters of the emergency start power supply. And when the judgment result is yes, it generates an emergency control operation for performing corresponding emergency power supply operations or power-off protection operations on the battery based on the electrical state parameters and detection feedback parameters, which can further improve the emergency power supply control of the battery and further ensure the healthy emergency control of the battery, timely trigger the power-off protection mechanism, so as to improve the comprehensiveness and accuracy of battery emergency control, which is beneficial to ensuring the service life of the battery and improving the application safety of the battery and the battery clip.

[0140] In this optional embodiment, as an optional implementation manner, the above-mentioned first state analysis control unit 202 is further configured to calculate the signal detection performance value of the detection module 10 based on the detection feedback parameters before the first parameter generation control unit 201 generates the module control parameters for the detection module 10 according to the detection feedback parameters. The signal detection performance value is used to represent the stability degree of the electrical signal detection connection between the detection module 10 and the battery.

[0141] The first state analysis control unit 202 is further configured to determine whether the signal detection performance value is greater than or equal to a preset signal detection performance threshold. When it is determined that the signal detection performance value is greater than or equal to the preset signal detection performance threshold, it triggers the first parameter generation control unit 201 to generate the module control parameters for the detection module 10 according to the detection feedback parameters.

[0142] In this optional embodiment, optionally, for the detection feedback parameters obtained from the above-mentioned GET_VOT1 and GET_VOT2 pins, a preset algorithm can be used to calculate the signal detection performance value representing the stability degree of the electrical signal detection connection between the detection module and the battery. Optionally, the absolute value of the difference between the detection feedback parameters obtained from the GET_VOT1 and GET_VOT2 pins can be calculated as the signal detection performance value. At this time, if the signal detection performance value is greater than or equal to the preset signal detection performance threshold, it can trigger the first parameter generation control unit to generate the module control parameters for the detection module according to the detection feedback parameters.

[0143] It can be seen that before the first parameter generation control unit generates module control parameters for the detection module according to the detection feedback parameters in implementing this optional embodiment, the first state analysis control unit calculates a signal detection performance value of the detection module for representing the stability of the electrical signal detection connection between the detection module and the battery according to the detection feedback parameters, which can further improve the stability and safety of the battery clip for battery state warning control, and is beneficial to further ensuring the use safety of the battery and the battery clip.

[0145] The second state analysis control unit 204 is further configured to determine whether the electrical state parameter of the acquired emergency start power supply is greater than or equal to a preset first state threshold parameter and whether the detection feedback parameter is less than or equal to a preset feedback threshold parameter;

[0146] And, optionally, as Figure 11 shown, Figure 11 A structural schematic diagram of a second parameter generation control unit is disclosed. The above-mentioned second parameter generation control unit 203 includes a third parameter generation control unit 2031, a relay 2032, and a multi-dimensional state detection unit 2033, where:

[0147] The first end of the third parameter generation control unit 2031 is electrically connected to the second end of the second state analysis control unit 204.

The second end of the relay 2032 is used to be electrically connected to the emergency start power supply. The third end of the relay 2032 is used to be electrically connected to the battery. The third end of the third parameter generation control unit 2031 is electrically connected to the first end of the multi-dimensional state detection unit 2033. The second end of the multi-dimensional state detection unit 2033 is electrically connected to the third end of the second state analysis control unit 204;

[0148] The third parameter generation control unit 2031 is configured to, when the judgment result of the second state analysis control unit 204 is yes, generate a first emergency control sub-parameter according to the electrical state parameter and the detection feedback parameter, so that the relay 2032 is closed and the emergency start power supply supplies power to the battery;

[0149] The multi-dimensional state detection unit 2033 is configured to detect multi-dimensional state parameters within a preset range of the battery;

[0150] The second state analysis control unit 204 is further configured to determine whether there is any state parameter in the multi-dimensional state parameters that is greater than or equal to a preset second state threshold parameter corresponding to the state parameter;

[0151] The third parameter generation control unit 2031 is further configured to generate a second emergency control sub-parameter when the second state analysis control unit 204 determines that any state parameter in the multi-dimensional state parameters is greater than or equal to the preset second state threshold parameter corresponding to the state parameter, so as to cause the relay 2032 to disconnect, and the emergency start power supply to suspend power supply to the battery;

[0152] Wherein, the multi-dimensional state parameters include at least one of a voltage state parameter, a current state parameter, a temperature state parameter, a humidity state parameter, a particulate matter distribution amount parameter, a charge operation state parameter, and a charge quantity state parameter.

[0153] In the embodiment of the present invention, specifically, the power-off protection operation may specifically include short-circuit protection: current protection during startup, when the current continuously exceeds 800 A for 20 ms, control the relay to disconnect; temperature protection: during startup, if the temperature continuously exceeds 60 °C for 30 s, control the relay to disconnect; backflow protection: during startup, if the voltage at the POWER+ terminal is greater than the voltage at the DC+ terminal pin corresponding to the emergency start power supply, control the relay to disconnect.

[0154] It can be seen that implementing this optional embodiment can further divide the second parameter generation control unit into a third parameter generation control unit, a relay, and a multi-dimensional state detection unit, so as to perform corresponding emergency control operations for emergency power supply or power-off protection operations on the battery. On the basis of improving the emergency power supply control of the battery, it can further ensure the healthy emergency control of the battery, timely trigger the power-off protection mechanism, so as to improve the comprehensiveness and accuracy of the battery emergency control, which is beneficial to ensuring the service life of the battery and improving the application safety of the battery and the battery clip.
