Description

It also protects and controls the battery charging process according to the battery characteristics to avoid damage to the battery due to improper charging. It is an important component of a car.

[0003] Currently, most car battery chargers are integrated with direct current (DC-DC) converters. However, the charger generates a lot of heat when charging the car battery, which causes overheating inside the DC-DC converter, which may cause the switching devices (such as MOS tubes) in the DC-DC topology to burn out, bringing adverse effects on the reliability of the charging process.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0018] Continue to collect the charging detection temperature of the DC conversion module in real time;

[0019] Determining whether the charging detection temperature is greater than or equal to the target threshold temperature and continues to rise;

[0020] If the charging detection temperature is greater than or equal to the target threshold temperature and continues to rise, the output control module stops outputting the charging current to the target battery.

[0021] In some embodiments, a step of determining whether the charging detection temperature is greater than or equal to the target threshold temperature and continues to rise is performed a preset number of times;

[0022] If the determination step for the preset number of times determines that the charging detection temperature is greater than or equal to the target threshold temperature and continues to rise, the output control module stops outputting the charging current to the target battery.

[0023] In some embodiments, after the charging detection temperature is less than the target threshold temperature, the charging control method further includes the following steps:

[0024] Continue to collect the charging detection temperature of the DC conversion module in real time, and determine whether the charging detection temperature is stable;

[0025] If the charging detection temperature is lower than the target threshold temperature and is stable, the output control module controls the charger to continuously output the current charging current to the target battery until charging is completed.

[0026] According to some embodiments, the present application also provides a charging control system for implementing the charging control method provided in the above embodiments to control the charging process of a charger, wherein the charger comprises a DC conversion module and an output control module connected to the DC conversion module, wherein the DC conversion module is used to convert an external voltage into a target charging voltage, and the output control module is used to adjust the charging current output by the charger to a target battery; the charger has at least a first charging gear and a second charging gear;

[0037] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application.

[0038] The embodiments of the present application may or at least have the following advantages:

According to the charging detection temperature of the DC conversion module, it is judged whether the charging detection temperature is greater than or equal to the target threshold temperature, and when the charging detection temperature is greater than or equal to the target threshold temperature, the current charging current is reduced until the charging detection temperature is less than the target threshold temperature. Since collecting the charging detection temperature of the DC conversion module can provide more accurate and timely temperature data, more efficient and accurate overheating protection is achieved, thereby avoiding the burning of the switching device in the DC conversion module, and effectively improving the safety and reliability of the charging process.

[0054] Currently, most car battery chargers are integrated with direct current (DC-DC) converters. However, the charger generates a lot of heat when charging the car battery, which causes overheating inside the DC-DC converter, which may cause the switching devices (such as MOS tubes) in the DC-DC topology to burn out, bringing adverse effects on the reliability of the charging process.

[0055] In view of the shortcomings of the related art, the present application provides a charging control method, system, electronic device and storage medium, which can prevent the switch device in the DC conversion module from being burned and effectively improve the safety and reliability of the charging process. The details will be described in the subsequent embodiments.

[0056] The charging control method provided in the present application can be used to control the charging process of the charger. It should be noted that the charger involved in the embodiment of the present application specifically includes a DC conversion module and an output control module connected to the DC conversion module. Among them, the DC conversion module is used to convert the external voltage into a target charging voltage, and the output control module is used to control the charging current output by the charger to the target battery. It can be understood that the charger can also include more other components known to those skilled in the art, and certain components can also be combined. This is not the focus of this application, so the specific structure and principle of the charger will not be repeated here.

[0057] It is particularly emphasized that the charger involved in the embodiment of the present application may have multiple different charging gears, and different charging gears may correspond to different charging voltages one by one. For example, the charger may have at least a first charging gear and a second charging gear.

[0058] The following uses the example of a charger having a first charging gear and a second charging gear to illustrate the charging control method provided in the embodiment of the present application. Figure 1 The charging control method provided in the embodiment of the present application may specifically include the following steps S100 to S400.

[0059] S100: Setting a first threshold temperature according to a first charging gear, and setting a second threshold temperature according to a second charging gear.

[0060] S200: In response to the selection of the charging gear, calling the target threshold temperature corresponding to the selected charging gear. For example, when the first charging gear is selected for charging, the first threshold temperature is called as the target threshold temperature; when the second charging gear is selected for charging, the second threshold temperature is called as the target threshold temperature.

[0061] S300: In the charging mode, the charging detection temperature of the DC conversion module is collected in real time, and it is determined whether the charging detection temperature is greater than or equal to the target threshold temperature.

[0062] S400: When it is determined that the charging detection temperature is greater than or equal to the target threshold temperature, the output control module reduces the current charging current until the charging detection temperature is less than the target threshold temperature.

[0063] The embodiment of the present application sets the first threshold temperature and the second threshold temperature one by one for different first charging gears and second charging gears, so that the corresponding threshold temperature can be called as the target threshold temperature according to the selection of the charging gear. The DC conversion module is a very important source of heat in the charging mode. By collecting the charging detection temperature of the DC conversion module in real time, the heating condition of the system can be accurately reflected, and the heat change inside the system can be captured more timely and accurately than monitoring the temperature of the housing or other remote parts of the system. According to the charging detection temperature of the DC conversion module, it is judged whether the charging detection temperature is greater than or equal to the target threshold temperature, and when the charging detection temperature is greater than or equal to the target threshold temperature, the current charging current is reduced until the charging detection temperature is less than the target threshold temperature. Since collecting the charging detection temperature of the DC conversion module can provide more accurate and timely temperature data, more efficient and accurate overheating protection is achieved, thereby avoiding the burning of the switching device in the DC conversion module, and effectively improving the safety and reliability of the charging process.

[0064] The execution subject of step S100 is a charging control system based on a computer program, which can be implemented using a microcontroller unit (MCU), but is not limited thereto.

[0065] It is particularly emphasized that the charger involved in the embodiment of the present application may also have more different charging gears, such as the third charging gear, the fourth charging gear, etc. Correspondingly, the threshold temperature may be set according to different charging gears; for example, the third threshold temperature is set according to the third charging gear, the fourth threshold temperature is set according to the fourth charging gear, etc., and so on.

[0066] As an example, the first threshold temperature may be set according to the first charging gear in the following manner, for example:

[0067] At the first charging gear, a first maximum charging current corresponding to the first charging gear is used to perform a charging test on the target battery, and a first test temperature of the DC conversion module during the charging test is collected as a first threshold temperature.

[0068] As an example, the second threshold temperature may be set according to the second charging gear in the following manner, for example:

[0069] At the second charging gear, a charging test is performed on the target battery using a second maximum charging current corresponding to the second charging gear, and a second test temperature of the DC conversion module during the charging test is collected as a second threshold temperature.

[0070] In the above embodiment, by performing charging tests at different charging gears and collecting the test temperature of the DC conversion module as the threshold temperature, the threshold temperature of each charging gear can be accurately set, effectively avoiding over-protection or under-protection, thereby improving the accuracy and safety of the charging process.

[0071] It can be understood that for more different charging gears, such as the third charging gear, the fourth charging gear, etc., the threshold temperature corresponding to each charging gear can be determined by using the maximum charging current corresponding to each charging gear to perform a charging test on the target battery and collecting the test temperature of the DC conversion module during the charging test.

[0072] In some embodiments, the first charging gear is defined as a charging gear with a smaller charging voltage (ie, the first charging voltage), and the second charging gear is defined as a charging gear with a larger charging voltage (ie, the second charging voltage).

[0073] It can be understood that when charging is performed with a lower charging voltage (i.e., the first charging voltage), the maximum charging current is also relatively large. At this time, the current passing through the rectifier tube is relatively large, and the heat generated by the rectifier tube needs to be radiated through the rear-stage radiator, resulting in the heating position being close to the rear stage, which refers to one side of the charging output terminal. When charging is performed with a higher charging voltage (i.e., the second charging voltage), the maximum charging current is relatively small. At this time, the switching device (such as the MOS tube) generates more heat, resulting in the heating position being close to the front stage, which refers to one side of the external power input terminal.

[0074] For example, a temperature sampling device (such as a negative temperature coefficient thermistor, also known as NTC) for collecting the charging detection temperature of the DC conversion module can be set close to the back stage. When charging with a higher charging voltage (i.e., the second charging voltage), the heating position is far away from the collection position, and the collected charging detection temperature of the DC conversion module will also be lower.

[0075] This embodiment takes into account the differences in heating positions at different charging gears and sets the second threshold temperature to be less than or equal to the first threshold temperature; that is, the first threshold temperature is greater than the second threshold temperature. In this way, even if the heating position is far away from the temperature collection position when the second charging gear is selected, the temperature abnormality can be accurately detected and the current charging current can be reduced in time, thereby protecting the switching device (especially the front-stage MOS tube) from overheating damage, further improving the safety and reliability of the system.

[0076] The charger may have more different charging gears. In the above embodiment, when the charging voltage corresponding to the charging gear is larger, a lower threshold temperature may be set accordingly.

[0077] In some embodiments, the charger may be a charger having a 12V charging gear and a 24V charging gear. In this embodiment, the first charging voltage is 12V and the second charging voltage is 24V, and the difference between the first threshold temperature and the second threshold temperature may be set to be greater than or equal to 40°C.

[0078] The charger involved in the above embodiment can be, for example, a car battery charger. In order to meet the needs of cars or other motor vehicles with different powers, a 12V charging gear and a 24V charging gear are set. The above embodiment further refines the temperature protection for different voltage gears by specifically setting the threshold temperature difference (≥40°C) between the 12V charging gear and the 24V charging gear, ensuring that the switch device will not be damaged due to heat accumulation at a higher voltage gear, further improving the safety of the charging process.

[0079] In some embodiments, after the output control module reduces the current charging current in step S400, the charging control method may further include: Figure 2 Steps S511 to S513 are shown.

[0080] S511: Continue to collect the charging detection temperature of the DC conversion module in real time.

[0081] S512: Determine whether the charging detection temperature is greater than or equal to the target threshold temperature and continues to rise.

[0082] S513: If the charging detection temperature is greater than or equal to the target threshold temperature and continues to rise, the output control module stops outputting the charging current to the target battery.

[0083] The above embodiment continues to monitor the charging detection temperature change of the DC conversion module after reducing the charging current. In this way, when the charging detection temperature is still greater than or equal to the target threshold temperature and continues to rise, charging can be stopped in time to prevent continuous overheating from damaging the charger and the target battery, thereby providing multiple safety guarantees for the charging process.

[0084] In some embodiments, step S512 is repeated a preset number of times, that is, the step of judging whether the charging detection temperature is greater than or equal to the target threshold temperature and continues to rise is repeated a preset number of times; if the judgment steps for the preset number of times all determine that the charging detection temperature is greater than or equal to the target threshold temperature and continues to rise, the output control module stops outputting the charging current to the target battery.

[0085] In the above embodiment, when judging whether the charging detection temperature is greater than or equal to the target threshold temperature and continues to rise, it is necessary to repeat the preset number of times. In this way, it can be ensured that charging is stopped only when it is confirmed multiple times that the charging detection temperature is greater than or equal to the target threshold temperature and continues to rise, avoiding unnecessary charging stops due to a single abnormal temperature fluctuation and maintaining the original charging efficiency.

[0086] The embodiment of the present application does not specifically limit the preset number of times the determination step is repeated, and can be adaptively set according to the needs of the actual application scenario.

[0087] In some embodiments, after the charging control method detects that the charging detection temperature is less than the target threshold temperature after executing step S400, it may also include the following steps: Figure 3 Steps S521 to S522 are shown.

[0088] S521: Continue to collect the charging detection temperature of the DC conversion module in real time, and determine whether the charging detection temperature is stable.

[0089] S522: If the charging detection temperature is lower than the target threshold temperature and is stable, the output control module controls the charger to continuously output the current charging current to the target battery until charging is completed.

[0090] After the charging detection temperature returns to normal, the above embodiment continues to monitor the charging detection temperature of the DC conversion module in real time and determines whether it is stable, ensuring that long-term continuous charging is performed within a safe temperature range, further improving the stability of the charging process.

[0091] It can be understood that stable charging detection temperature means that within a certain time range, the collected charging detection temperature fluctuates within a preset range without a significant upward or downward trend. This application does not specifically limit the standard for defining stable charging detection temperature, and can be adaptively set according to the thermal design characteristics of the system, the heat resistance of the internal components of the charger, and the safety protection requirements of the actual application scenario.

[0092] The following combination Figure 4 The charging control methods in some of the above embodiments are explained more clearly.

[0093] Use a charger with 12V and 24V charging gears to charge the target battery. First, connect an external power source, such as a mains, and select a charging gear. If the 12V charging gear is selected, the target battery is charged with a 12V charging voltage; if the 24V charging gear is selected, the target battery is charged with a 24V charging voltage.

[0094] The DC conversion module has many components, for example, it may include a switch device and a rectifier tube. The switch device may include but is not limited to a MOS tube.

[0095] When charging at 12V, the maximum charging current is 8A. At this time, the rectifier tube generates heat and radiates heat through the rear stage radiator, so the heating position is close to the rear stage. When charging at 24V, the maximum charging current is 4A. At this time, the front stage MOS tube generates more heat, so the heating position is close to the front stage.

[0096] When setting the threshold temperature in the embodiment of the present application, different threshold temperatures are set correspondingly to the heating positions of the 24V charging gear and the 12V charging gear, taking into account the difference between the heating positions of the 24V charging gear and the 12V charging gear.

[0097] When charging at the 12V charging gear, the charging detection temperature of the DC conversion module is collected in real time. When the collected charging detection temperature reaches the first threshold temperature, the output starts to slowly derate, such as reducing the current charging current, until the charging detection temperature stabilizes. Correspondingly, when charging at the 24V charging gear, the charging detection temperature of the DC conversion module is collected in real time. When the collected charging detection temperature reaches the second threshold temperature, the output starts to slowly derate, such as reducing the charging current, until the charging detection temperature drops below the target threshold temperature and remains stable, then the current charging current is continuously output until charging is completed.

[0098] During the derating output process, if the charging detection temperature is still greater than or equal to the target threshold temperature and continues to rise, the charging current output to the target battery is stopped.

[0099] Based on the same inventive concept, the embodiment of the present application also provides a charging control system for implementing the charging control method involved above. The implementation scheme for solving the problem provided by the charging control system is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more charging control system embodiments provided below can refer to the limitations on the charging control method above. The technical effects that can be achieved by the above charging control method can also be achieved by the charging control system, and no further details will be given here.

[0100] See also Figure 5The charging control system may specifically include a setting unit 10 , a calling unit 20 , a processing unit 30 and a control unit 40 .

[0101] The setting unit 10 is used to set a first threshold temperature according to a first charging gear, and to set a second threshold temperature according to a second charging gear; the calling unit 20 calls a target threshold temperature corresponding to the selected charging gear in response to the selection of the charging gear; the processing unit 30 is used to collect the charging detection temperature of the DC conversion module in real time in the charging mode, and to determine whether the charging detection temperature is greater than or equal to the target threshold temperature; when it is determined that the charging detection temperature is greater than or equal to the target threshold temperature, the control unit 40 sends a control instruction to the output control module to reduce the current charging current, and controls the output control module to reduce the current charging current until the charging detection temperature is less than the target threshold temperature.

[0102] It can be understood that each module in the above charging control system can be implemented in whole or in part by software, hardware, or a combination thereof. Each module can be embedded in or independent of a processor in a computer device in the form of hardware, or can be stored in a memory in a computer device in the form of software, so that the processor can call and execute operations corresponding to each module.
