Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a voltage regulation method, device, electronic device, and storage medium. Background Art

[0002] With the rapid growth of electric vehicle ownership, the lack of charging infrastructure and the long charging times are becoming increasingly apparent. As a result, electric vehicle range has become a key factor in consumer choice. Related technologies often employ low-voltage energy management. Specifically, when the high-voltage battery pack's SOC (State of Charge) falls below a preset lower limit, the charge information is transmitted to the vehicle control unit. The control unit then disconnects the comfort load control relay, limiting the power consumption of the comfort loads. This reduces vehicle energy consumption and extends vehicle range.

[0003] However, this will limit the normal use of some vehicle functions, bring inconvenience to users, and reduce their car-using experience. Summary of the Invention

[0004] The main purpose of this application is to provide a voltage regulation method, device, electronic device and storage medium, aiming to solve the technical problem in related technologies of improving the range of electric vehicles through low-voltage energy management, resulting in reduced convenience in using the vehicle.

[0005] To achieve the above objectives, the present application provides a voltage regulation method, which is applied to an electric vehicle and includes the following steps:

[0006] detecting a measured load voltage of at least one functional module on the electric vehicle;

[0007] Obtaining a set voltage corresponding to each of the functional modules;

[0008] The output voltage of the DC converter on the electric vehicle is adjusted according to each of the measured load voltages and each of the set voltages.

[0009] The present application also provides a voltage regulating device, which is applied to an electric vehicle and includes:

[0010] a detection module, configured to detect a measured load voltage of at least one functional module on the electric vehicle;

[0011] An acquisition module, used to acquire the set voltage corresponding to each of the functional modules;

[0012] The regulating module is used to regulate the output voltage of the DC converter on the electric vehicle according to each of the measured load voltages and each of the set voltages.

[0013] The present application also provides an electronic device, which is a physical device, and includes: a memory, a processor, and a program of the voltage regulation method stored in the memory and capable of running on the processor. When the program of the voltage regulation method is executed by the processor, the steps of the voltage regulation method as described above can be implemented.

[0014] The present application also provides a storage medium, which is a computer-readable storage medium. The computer-readable storage medium stores a program for implementing the voltage regulation method. When the program of the voltage regulation method is executed by a processor, the steps of the voltage regulation method as described above are implemented.

[0015] The present application provides a voltage regulation method, device, electronic device and storage medium. The voltage regulation method is applied to an electric vehicle. By detecting the measured load voltage of at least one functional module on the electric vehicle, the set voltage corresponding to each functional module is obtained, thereby determining the current actual voltage value and the set voltage value of each load on the electric vehicle. The set voltage can represent the voltage requirement of each load, and the measured load voltage can represent the voltage actually supplied to each functional module. Then, by adjusting the output voltage of the DC converter on the electric vehicle according to each measured load voltage and each set voltage, the output voltage of the DC converter is dynamically adjusted to adapt to the voltage requirements of each load, thereby realizing dynamic adjustment of the load voltage of each load on the electric vehicle based on the difference in voltage supply and demand of each functional module. In the case where supply exceeds demand, it will lead to waste of electric energy. In the case where demand exceeds supply, it may affect the normal use of functional modules or even damage the functional modules. Therefore, by dynamically adjusting the output voltage of the DC converter based on the difference in voltage supply and demand of each functional module, the load voltage of each load on the electric vehicle is dynamically adjusted to make the supply of each functional module closer to its demand. In this way, not only can the power consumption of the entire vehicle be reduced and the battery life be extended while meeting the needs of each functional module, but there is no need to restrict the functions of the vehicle, which has little impact on the user's use of the vehicle. It overcomes the technical defects of the related technology of improving the battery life of electric vehicles through low-voltage energy management, which limits the normal use of some vehicle functions, brings inconvenience to users, and reduces the user's car experience, and provides a more convenient method to improve the battery life of electric vehicles.

[0024] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0025] Example 1

[0026] The present application provides a voltage regulation method. In the first embodiment of the voltage regulation method of the present application, referring to Figure 1 , the voltage regulation method is applied to an electric vehicle, comprising the following steps:

[0027] Step S10, detecting a measured load voltage of at least one functional module on the electric vehicle;

[0028] The executor of the method of this embodiment can be a voltage regulating device, or a voltage regulating terminal device or server. This embodiment takes a voltage regulating device as an example. The voltage regulating device can be integrated into a terminal device such as a vehicle with data processing function, a vehicle controller, an on-board terminal, a smart phone, a tablet computer, etc.

[0029] In this embodiment, it should be noted that the voltage regulation method is applied to electric vehicles, which are vehicles that can be driven by electricity, including at least pure electric vehicles and hybrid electric vehicles. Current electric vehicles typically include a generator, a direct current (DC / DC) converter (DCDC), and at least one functional module. The generator charges the high-voltage battery system, and the DCDC converts the high-voltage direct current into the low-voltage power required by the low-voltage power supply circuit to power each of the functional modules.

[0030] Exemplarily, the step S10 includes: after the electric vehicle is powered on, continuously or periodically detecting the measured load voltage of at least one functional module on the electric vehicle.

[0031] In one practicable manner, the measured load voltage of at least one functional module on the electric vehicle may be detected by a chip in a smart fuse box.

[0032] Optionally, the step of detecting a measured load voltage of at least one functional module on the electric vehicle includes:

[0033] At every preset time period, the measured load voltage of at least one functional module on the electric vehicle is detected.

[0034] In this embodiment, to ensure that functional modules with higher voltage requirements can function normally, the DCDC output voltage needs to be set relatively high. However, if these functional modules are not in use, the higher output voltage will result in unnecessary energy waste. During vehicle driving, certain functional modules may be irregularly turned on or off depending on the circumstances encountered. Therefore, the measured load voltage of each functional module can be periodically detected to periodically monitor whether there is energy waste. The preset time period can be determined based on actual needs and actual vehicle test results, and this embodiment does not impose any restrictions on this.

[0035] Step S20, obtaining the set voltage corresponding to each of the functional modules;

[0036] In this embodiment, it should be noted that the set voltage refers to a pre-set minimum voltage that can ensure the normal operation of the functional module, and can be determined in advance based on at least one parameter of each functional module, such as the rated voltage, circuit connection condition, and loop voltage drop. Among them, the loop voltage drop includes at least one of the wiring harness voltage drop, terminal voltage drop, and solder point voltage drop. After the circuit corresponding to the DCDC is determined, the set voltage corresponding to each functional module in the circuit can be determined.

[0037] In an practicable manner, for each functional module, the sum of the load rated voltage of the functional module and the loop voltage drop corresponding to the functional module may be determined as the set voltage of the functional module.

[0038] In one feasible manner, after the set voltage is predetermined, the mapping relationship between each set voltage and each functional module can be made into a mapping relationship table and stored in the storage unit of the chip in the smart fuse box for direct call and query during subsequent voltage adjustment.

[0039] Exemplarily, the step S20 includes: determining the set voltage corresponding to each functional module according to a preset mapping relationship between the set voltage and the functional module.

[0040] Step S30 , adjusting the output voltage of the DC converter on the electric vehicle according to the measured load voltages and the set voltages.

[0041] In this embodiment, it should be noted that the measured load voltage can represent the voltage actually supplied to each functional module, and the set voltage can represent the voltage requirement of each functional module. The measured load voltage is usually determined by the output voltage of the DCDC. Since it is necessary to ensure the normal use of each functional module in the circuit, the output voltage of the DCDC is usually determined by the maximum set voltage in the circuit. Therefore, there may be a situation where the supplied voltage exceeds its actual demand. Therefore, based on the measured load voltage and the set voltage of each functional module, the supply and demand difference between the actual load voltage and the voltage requirement can be determined. When the supply exceeds the demand, it will lead to waste of electric energy. When the demand exceeds the supply, it may affect the normal use of the functional module or even damage the functional module. When a function module with a higher set voltage is turned on, in order to ensure the normal use of the function module with a higher set voltage, a higher DCDC output voltage needs to be set. When a function module with a higher set voltage is not turned on, for example, the set voltage of the air spring function module is higher, but the usage rate is lower. To ensure its normal use, the DCDC output voltage will be higher. However, during normal driving of the vehicle, when the air spring function module is not needed, other function modules do not need such a high voltage, which will result in unnecessary waste of electricity. For example, when the set voltage of the steering function module is higher, when the vehicle is driving on a highway with a lot of straight lines, the usage rate of the steering function module is lower, and other function modules do not need such a high voltage, which will also result in unnecessary waste of electricity. By dynamically adjusting the DCDC output voltage based on the difference in voltage supply and demand of each function module, and thus dynamically adjusting the load voltage of each load on the electric vehicle, the supply of each function module actually turned on can be closer to its demand, thereby reducing electricity consumption, reducing energy waste, and extending vehicle endurance.

[0042] Exemplarily, step S30 includes: first, determining the current supply and demand difference of each functional module based on the measured load voltage and set voltage corresponding to each functional module, wherein the smaller the supply and demand difference, the closer the voltage supplied by the functional module is to the required voltage, and the larger the supply and demand difference, the greater the difference between the voltage supplied by the functional module and the required voltage; and then, adjusting the output voltage of the DC converter on the electric vehicle to decrease or increase based on the supply and demand difference of one or more functional modules. The current supply and demand difference of each functional module can be represented by the difference, ratio, etc. between the measured load voltage and the set voltage corresponding to each functional module, and the magnitude relationship between the voltage supply and the voltage demand can be further determined based on the numerical value of the difference, ratio, etc.

[0043] In one practicable manner, the output voltage of the DC converter on the electric vehicle can be adjusted to decrease or increase based on the minimum supply-demand difference, the average supply-demand difference, or the supply-demand difference corresponding to the maximum measured load voltage. Although the adjustment range of the output voltage is small when adjusting the output voltage based on the minimum supply-demand difference, it can fully ensure the safety and stability of the output voltage after adjustment. Since the output voltage of the DCDC is generally determined by the set voltage of the functional module with the maximum voltage demand, if the supply-demand difference between the maximum measured load voltage and its corresponding set voltage is large, the supply-demand difference between other smaller measured load voltages and their corresponding set voltages will generally be even greater. In this case, it can be indicated that the functional module that may have a greater voltage demand is not currently turned on.

[0044] In one practicable manner, when the voltage supply is greater than the voltage demand, the excess voltage will cause waste of electric energy. Therefore, the output voltage of the DC converter may be reduced to reduce the consumption of electric energy.

[0045] In one practicable manner, when the voltage supply is less than the voltage demand, the output voltage of the DC converter may be increased and regulated to ensure normal use of the functional module and avoid low voltage damage to the functional module.

[0046] Optionally, the step of adjusting the output voltage of the DC converter on the electric vehicle according to each of the measured load voltages and each of the set voltages includes:

[0047] Step S31, determining a target functional module that meets a preset voltage condition according to each of the measured load voltages and each of the set voltages, and determining a first target measured load voltage and a target set voltage corresponding to the target functional module;

[0048] Step S32 : adjusting the output voltage of the DC converter on the electric vehicle according to the first target measured load voltage and the target set voltage.

[0049] In this embodiment, it should be noted that for electrical components, if the supplied voltage is significantly lower than the required voltage, there is a risk of malfunction or even damage. Therefore, the output voltage of the DCDC needs to be greater than the maximum set voltage in the circuit. Therefore, when adjusting the output voltage of the DCDC, the DCDC only needs to meet the voltage requirements of some functional modules to meet the voltage requirements of all functional modules, without having to analyze each functional module. This can effectively reduce the amount of calculation, improve voltage regulation efficiency, and reduce the waste of resources required for calculation. The preset voltage condition can be that the voltage difference between the measured load voltage and the set voltage corresponding to the same functional module is the smallest, or it can be that the measured load voltage is the largest, etc. The specific determination can be based on actual conditions and is not limited in this embodiment. The method of determining the functional module with the largest measured load voltage as the target functional module has a smaller amount of calculation, can improve the efficiency of voltage regulation, and reduce the waste of resources required for calculation.

[0050] Exemplarily, steps S31 to S32 include: determining whether the measured load voltage and the set voltage of each functional module meet the preset voltage condition, determining at least one functional module that meets the preset voltage condition as the target functional module, and determining the measured load voltage of the target functional module as the first target measured load voltage, and determining the set voltage of the target functional module as the target set voltage; and then, based on the supply and demand difference between the first target measured load voltage and the target set voltage, and in combination with a preset safety floating value, adjusting the output voltage of the DC converter on the electric vehicle, wherein the safety floating value refers to a value set to ensure the safe use of the functional module, which can be set specifically according to actual conditions, and this embodiment does not impose any restrictions on this.

[0051] In one illustrative embodiment, the output voltage of the DC converter on the electric vehicle can be adjusted based on the supply and demand difference between the first target measured load voltage and the target set voltage by calculating a ratio between the first target measured load voltage and the target set voltage, multiplying the current output voltage of the DC converter on the electric vehicle by the ratio, and further combining the ratio with a preset safety float value to obtain a target output voltage, and adjusting the output voltage of the DC converter on the electric vehicle to the target output voltage. For example, if the ratio between the first target measured load voltage and the target set voltage is 0.9 and the current output voltage of the DC converter is 13V, the output voltage of the DC converter can be adjusted to 13×0.9=11.7V. Alternatively, if the safety float value is 0.5V, the output voltage of the DC converter can be adjusted to 13×0.9+0.5=12.2V. If the safety float value is +5%, the output voltage of the DC converter can be adjusted to 13×0.9×105%=12.285V.

[0052] Optionally, the step of adjusting the output voltage of the DC converter on the electric vehicle according to the first target measured load voltage and the target set voltage includes:

[0053] Step S321, comparing the first target measured load voltage with the target set voltage;

[0054] Step S322 : When the first target measured load voltage is higher than the target set voltage, the output voltage of the DC converter on the electric vehicle is reduced and regulated according to the first target measured load voltage and the target set voltage.

[0055] In this embodiment, it should be noted that the output voltage of the DCDC is usually determined according to the maximum set voltage to ensure the normal use of each functional module. Therefore, when the functional module corresponding to the maximum set voltage is not turned on, reducing the output voltage of the DCDC can also ensure the normal use of each functional module in the turned-on state, save energy, and extend the battery life.

[0056] Exemplarily, steps S321 to S322 include: comparing the first target measured load voltage and the target set voltage; when the first target measured load voltage is higher than the target set voltage, reducing and adjusting the output voltage of the DC converter on the electric vehicle according to the first target measured load voltage and the target set voltage; when the first target measured load voltage is lower than the target set voltage, the vehicle may have a fault or a short-term fluctuation, and a fault prompt may be given, or the output voltage of the DC converter on the electric vehicle may be increased, or the process may return to executing the step of detecting the measured load voltage of at least one functional module on the electric vehicle for continuous monitoring.

[0057] Optionally, the step of adjusting the output voltage of the DC converter on the electric vehicle according to the first target measured load voltage and the target set voltage includes:

[0058] The output voltage of the DC converter on the electric vehicle is adjusted according to the difference between the first target measured load voltage and the target set voltage.

[0059] Exemplarily, the difference between the first target measured load voltage and the target set voltage is calculated, and the current output voltage of the DC converter on the electric vehicle is subtracted from the difference. The target output voltage can also be obtained by combining with a preset safety float value, and the output voltage of the DC converter on the electric vehicle is adjusted to the target output voltage. For example, if the difference between the first target measured load voltage and the target set voltage is 1.5V and the current output voltage of the DCDC is 16V, the output voltage of the DCDC can be adjusted to 16-1.5=14.5V. Alternatively, if the safety float value is 0.5V, the output voltage of the DCDC can be adjusted to 16-1.5+0.5=15V. If the safety float value is +5%, the output voltage of the DCDC can be adjusted to (16-1.5)×105%=15.225V.

[0060] In one practicable manner, referring to Figure 2The voltage regulation method includes the following steps: a central control unit sets a cycle period. When the cycle period is reached, the intelligent fuse box detects the measured load voltage of each functional module, obtains the set voltage of each functional module, and compares the measured load voltage of each functional module with the set voltage. If the measured load voltage of the target functional module is not greater than the set voltage, the method returns to wait for the next cycle period. If the measured load voltage of the target functional module is greater than the set voltage, the intelligent HSD (High-side Driver) chip in the intelligent fuse box calculates a voltage adjustment value, and feeds a signal back to the central control unit via the CAN (Controller Area Network) network. The central control unit determines whether the voltage adjustment value meets the safety load requirement based on the feedback signal. If it is determined that the voltage adjustment value does not meet the safety load requirement, the method returns to wait for the next cycle period. If it is determined that the voltage adjustment value meets the safety load requirement, the method requests the DC-DC converter to reduce the output voltage through the central control unit. After completing one voltage regulation cycle, the method waits for the next cycle period, thereby achieving periodic voltage regulation.

[0061] In this embodiment, the voltage regulation method is applied to an electric vehicle. By detecting the measured load voltage of at least one functional module on the electric vehicle, the set voltage corresponding to each functional module is obtained, thereby realizing the determination of the current actual voltage value and the set voltage value of each load on the electric vehicle. The set voltage can represent the voltage requirement of each load, and the measured load voltage can represent the voltage actually supplied to each functional module. Then, by adjusting the output voltage of the DC converter on the electric vehicle according to each measured load voltage and each set voltage, the output voltage of the DC converter is dynamically adjusted to adapt to the voltage requirements of each load, thereby realizing dynamic adjustment of the load voltage of each load on the electric vehicle based on the difference in voltage supply and demand of each functional module. In the case where supply exceeds demand, it will lead to waste of electric energy. In the case where demand exceeds supply, it may affect the normal use of functional modules or even damage the functional modules. Therefore, by dynamically adjusting the output voltage of the DC converter based on the difference in voltage supply and demand of each functional module, the load voltage of each load on the electric vehicle is dynamically adjusted to make the supply of each functional module closer to its demand. In this way, not only can the power consumption of the entire vehicle be reduced and the battery life be extended while meeting the needs of each functional module, but there is no need to restrict the functions of the vehicle, which has little impact on the user's use of the vehicle. It overcomes the technical defects of the related technology of improving the battery life of electric vehicles through low-voltage energy management, which limits the normal use of some vehicle functions, brings inconvenience to users, and reduces the user's car experience, and provides a more convenient method to improve the battery life of electric vehicles.

[0062] Example 2

[0063] Further, referring to FIG. 3 , based on the above embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above embodiment can be referred to above and will not be described in detail. On this basis, the step of reducing and adjusting the output voltage of the DC converter on the electric vehicle according to the first target measured load voltage and the target set voltage includes:

[0064] Step S3221, determining a voltage adjustment value according to the first target measured load voltage and the target set voltage;

[0065] In this embodiment, it should be noted that increasing the output voltage of the DCDC usually only results in a waste of electric energy, while reducing the output voltage of the DCDC may cause the functional modules to malfunction or even be damaged. Therefore, before reducing the output voltage of the DCDC, a safety test is required to ensure the safety of the vehicle.

[0066] Exemplarily, the step S3221 includes: determining a ratio, a difference, or other algorithm output value between the first target measured load voltage and the target set voltage as a voltage adjustment value.

[0067] Step S3222, detecting whether the voltage adjustment value meets the safety load requirement;

[0068] Exemplarily, step S3222 includes calculating the output voltage of the DCDC based on the voltage adjustment value, calculating an estimated value of the measured load voltage of at least one functional module on the electric vehicle based on a preset DCDC voltage distribution algorithm, and determining whether each of the estimated values ​​of the measured load voltage meets a safety load requirement. The safety load requirement may be no less than a set voltage. Since voltage may fluctuate, and minor fluctuations do not necessarily affect safety, a safety voltage threshold may be pre-set. The safety load requirement may be no less than the preset safety voltage threshold.

[0069] Optionally, the step of detecting whether the voltage adjustment value meets the safety load requirement includes:

[0070] Step S32221, determining an estimated voltage of each safety load according to a second target measured load voltage of at least one safety load on the electric vehicle and the voltage adjustment value;

[0071] Step S32222: When it is determined that each of the estimated voltages is higher than the corresponding preset safety voltage threshold, determine whether the voltage adjustment value meets the safety load requirement.

[0072] Exemplarily, steps S32221 to S32222 include: determining the second target measured load voltage corresponding to each of the safety loads from each of the measured load voltages according to a predetermined safety load, inputting the voltage adjustment value and each of the second target measured load voltages into a preset DCDC voltage distribution algorithm, calculating an estimated voltage for each of the safety loads, comparing the estimated voltage of each of the safety loads with the corresponding preset safety voltage threshold, and determining that the voltage adjustment value meets the safety load requirement when it is determined that each of the estimated voltages is higher than the corresponding preset safety voltage threshold; and determining that the voltage adjustment value meets the unsafe load requirement when it is determined that any one of the estimated voltages is not higher than the corresponding preset safety voltage threshold.

[0073] Step S3223: When it is determined that the voltage adjustment value meets the safety load requirement, the output voltage of the DC converter on the electric vehicle is reduced and adjusted according to the voltage adjustment value.

[0074] Exemplarily, the step S3223 includes: when it is determined that the voltage adjustment value meets the safety load requirements, reducing and adjusting the output voltage of the DC converter on the electric vehicle according to the voltage adjustment value; when it is determined that the voltage adjustment value does not meet the safety load requirements, the DCDC may not be adjusted, and the voltage adjustment may be performed in the next cycle.

[0075] In this embodiment, during the voice interaction process, if the user cannot obtain any response or feedback after outputting the voice, the user experience will be poor and the problem cannot be solved. For situations where the command cannot be executed, the voice interaction can flexibly provide feedback, allowing the user to clear the obstacle in time and complete the control of the back door in time, thereby improving the user experience.
