Description

Technical Field

[0001] This application relates to the field of vehicle control technology, and in particular to charging control methods, devices, equipment and storage media. Background Technology

[0002] When a vehicle battery is charged at high charge (SOC) or at low temperature, the battery can only allow a small charging current. Charging stations that use high current can easily cause overcurrent, and prolonged overcurrent can cause irreversible damage to the battery cells, reduce their lifespan, and in severe cases, even lead to thermal runaway.

[0003] The relevant technology reports a fault and stops charging as soon as it detects overcurrent charging, without making any adjustments or handling. This "one-size-fits-all" strategy, while ensuring safety, seriously reduces the user's actual experience. Summary of the Invention

[0004] The main purpose of this application is to provide a charging control method, device, equipment and storage medium, which aims to solve the technical problem that the related technology does not adjust or handle overcurrent charging, resulting in a poor user experience.

[0005] To achieve the above objectives, this application proposes a charging control method, the method comprising: The vehicle requests charging from the charging pile based on the vehicle's requested current and obtains the charging pile's output current or the battery's inflow current. The vehicle's requested current is constructed based on the charging current demanded by the vehicle's battery and the power consumption current of the in-vehicle equipment. The overcurrent amount is determined based on the output current of the charging pile or the inflow current of the battery. If the overcurrent duration is less than or equal to the preprocessing duration threshold, the vehicle's requested current is adjusted based on the overcurrent amount, and the process returns to the step of requesting charging from the charging pile based on the vehicle's requested current and obtaining the charging pile's output current.

[0006] Optionally, after determining the overcurrent based on the output current of the charging pile or the inflow current of the battery, the method further includes: If the overcurrent duration is greater than the preprocessing duration threshold and less than or equal to the fault determination duration threshold, then the power to be consumed is determined based on the overcurrent amount. The motor operating power is determined based on the power to be consumed. The motor is controlled to operate based on its operating power, and the actual operating power of the motor is obtained. If the actual operating power is consistent with the power to be consumed, then return to the step of determining the overcurrent based on the output current of the charging pile or the inflow current of the battery.

[0007] Optionally, after controlling the motor operation based on the motor operating power and obtaining the actual operating power of the motor, the method further includes: If the actual operating power is inconsistent with the power to be consumed, then the power difference is determined based on the actual operating power and the power to be consumed. The motor operating power is corrected based on the power difference to generate a new motor operating power, and the process returns to the step of controlling the motor operation based on the motor operating power.

[0008] Optionally, controlling the motor operation based on the motor's operating power and obtaining the motor's actual operating power includes: The motor operation is controlled based on the motor operating power, and the motor temperature is obtained; If the motor temperature is less than or equal to the over-temperature warning threshold, then the actual operating power of the motor is obtained.

[0009] Optionally, after controlling the motor operation based on the motor operating power and obtaining the motor temperature, the method further includes: If the motor temperature is greater than the over-temperature warning threshold but less than the over-temperature fault threshold, the motor operating power is reduced to generate a new motor operating power, and the process returns to the steps of controlling the motor operation based on the motor operating power and obtaining the motor temperature.

[0010] Optionally, determining the motor operating power based on the power to be consumed includes: Determine if the sign prohibiting compensation exists; If not, the motor operating power is determined based on the power to be consumed; Accordingly, after controlling the motor operation based on the motor operating power and obtaining the motor temperature, the method further includes: If the motor temperature is greater than or equal to the over-temperature fault threshold, the motor is controlled to stop running, a compensation prohibition flag is set, and the process returns to the step of determining whether the compensation prohibition flag exists.

[0011] Optionally, determining the overcurrent based on the output current of the charging pile or the inflow current of the battery further includes: If the output current of the charging pile is greater than the requested current of the vehicle, or if the inflow current of the battery is greater than the charging demand current, then the overcurrent amount is determined based on the output current of the charging pile or the inflow current of the battery.

[0012] Furthermore, to achieve the above objectives, this application also proposes a charging control device, which includes: The request module is used to request charging from the charging pile based on the vehicle's requested current, and to obtain the charging pile's output current or the battery's inflow current. The vehicle's requested current is constructed based on the charging demand current of the vehicle's battery and the power consumption current of the in-vehicle equipment. The determination module is used to determine the overcurrent based on the output current of the charging pile or the inflow current of the battery. The control module is used to adjust the vehicle's requested current based on the overcurrent amount if the overcurrent duration is less than or equal to the preprocessing duration threshold, and then return to the steps of requesting charging from the charging pile based on the vehicle's requested current and obtaining the charging pile's output current.

[0013] In addition, to achieve the above objectives, this application also proposes a charging control device, the device comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, the computer program being configured to implement the steps of the charging control method as described above.

[0014] In addition, to achieve the above objectives, this application also proposes a storage medium, which is a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, it implements the steps of the charging control method described above.

[0015] In addition, to achieve the above objectives, this application also provides a computer program product, which includes a computer program that, when executed by a processor, implements the steps of the charging control method described above.

[0016] One or more technical solutions proposed in this application have at least the following technical effects: When overcurrent charging is detected during the charging process, instead of directly reporting a fault, it first attempts to adjust the vehicle's requested current based on the amount of overcurrent to try to reduce the charging pile's output current, thereby eliminating the overcurrent charging situation and ensuring that charging is not directly interrupted due to overcurrent charging, thus improving the user's actual experience.

[0020] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0021] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0022] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Based on this, embodiments of this application provide a charging control method, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the charging control method of this application.

[0024] In this embodiment, the charging control method includes steps S10 to S30: Step S10: Request charging from the charging pile based on the vehicle's requested current, and obtain the charging pile's output current or the battery's inflow current. The vehicle's requested current is constructed based on the vehicle battery's charging demand current and the device's power consumption current in the vehicle.

[0025] It should be noted that the executing entity in this embodiment can be the vehicle itself or the charging control device. The charging control device can be a controller installed in the vehicle, such as an ECU controller, or other controllers that can achieve the same or similar functions. This embodiment does not limit this. In this embodiment and the following embodiments, the charging control device is used as an example to describe the charging control method of this application.

[0026] It should be noted that the vehicle requested current is constructed based on the charging current demanded by the vehicle battery and the device power consumption current of the in-vehicle equipment. For example, the sum of the charging current demanded by the vehicle battery and the device power consumption current of the in-vehicle equipment can be used as the vehicle requested current.

[0027] The charging current requirement of a vehicle battery can be the current allowed to flow into the battery during the current charging process. This can be obtained from a charging map based on the battery's remaining charge (SOC) and battery temperature. The charging map can be preset by the charging control equipment administrator or the vehicle manufacturer. The device current consumption of in-vehicle equipment can be the current value of the currently operating electrical devices in the vehicle.

[0028] The charging pile output current can be the amount of current that the charging pile outputs to the vehicle when charging is requested; the battery inflow current can be the amount of current that actually flows into the vehicle battery when the vehicle is charging.

[0029] Step S20: Determine the overcurrent amount based on the output current of the charging pile or the inflow current of the battery.

[0030] In practical applications, the absolute value of the difference between the charging pile's output current and the vehicle's requested current can be used as the overcurrent. Alternatively, the absolute value of the difference between the battery's inflow current and the vehicle's battery's charging demand current can be used as the overcurrent.

[0031] It is understandable that, since current has direction, and during charging, the current direction is from the outside into the battery, the current value is negative. Therefore, when calculating the overcurrent, the absolute value of the difference can be used as the overcurrent.

[0032] The specific calculation method to be used can be selected based on the current sensor settings in the vehicle. For example, if the current sensor in the vehicle can only collect the output current of the charging pile, the overcurrent can be determined based on the output current of the charging pile. If the current sensor in the vehicle can only collect the current flowing into the battery, the overcurrent can be determined based on the current flowing into the battery. If the current sensor in the vehicle can simultaneously collect the battery inflow current and the charging pile output current, then either one can be selected to determine the overcurrent amount according to the requirements.

[0033] In a specific implementation, to ensure that processing is only performed during actual overcurrent events, step S20 in this embodiment may include: If the output current of the charging pile is greater than the requested current of the vehicle, or if the inflow current of the battery is greater than the charging demand current, then the overcurrent amount is determined based on the output current of the charging pile or the inflow current of the battery.

[0034] It should be noted that, in order to reduce unnecessary processing, when there is no overcurrent charging, there is no need to calculate the overcurrent value and you can charge directly under normal conditions. The overcurrent value is only calculated when there is an overcurrent charging situation.

[0035] In reality, whether overcurrent charging exists can be determined by comparing the output current of the charging pile with the current requested by the vehicle, or by comparing the current flowing into the battery with the current required for charging.

[0036] In practical use, since the current is generally negative during charging, in order to make a reasonable judgment, when determining the magnitude of the charging pile output current and the vehicle's requested current, as well as the magnitude of the battery's inflow current and the charging demand current, the absolute values ​​of the two can be compared. For example, if the absolute value of the charging pile output current is greater than the absolute value of the vehicle's requested current, then it is determined that the charging pile output current is greater than the vehicle's requested current.

[0037] It is understandable that if the charging pile output current is greater than the vehicle's requested current, it means that the current output by the charging pile is greater than the actual current requested by the vehicle. Therefore, it can be determined that there is overcurrent charging, and thus the amount of overcurrent can be determined. If the battery current flowing into the battery is greater than the charging current required, it means that the actual current flowing into the vehicle battery is greater than the actual required current. Therefore, it can be determined that there is overcurrent charging, and the amount of overcurrent can be determined.

[0038] Similarly, whether to choose to compare the charging pile output current with the vehicle's requested current or to compare the battery's inflow current with the charging demand current can be selected based on the current sensor settings in the vehicle. The principle is similar to the method of selecting which data to calculate the overcurrent, so it will not be elaborated here.

[0039] Step S30: If the overcurrent duration is less than or equal to the preprocessing duration threshold, adjust the vehicle request current based on the overcurrent amount, and return to the step of requesting charging from the charging pile based on the vehicle request current and obtaining the charging pile output current.

[0040] It should be noted that the overcurrent duration can be the duration during which the overcurrent charging state is maintained. The preprocessing duration threshold can be the difference between the fault determination duration threshold and the current dynamic adjustment filtering duration.

[0041] The fault determination time threshold can be a maximum value representing the duration for which the battery can maintain overcurrent charging without damage, while the current dynamic adjustment filtering time can be a value representing the balance between the battery system's response speed to current signals and its anti-interference capability. Both the fault determination time threshold and the current dynamic adjustment filtering time can be preset or calibrated by the administrator of the charging control equipment.

[0042] In practical use, if the duration of overcurrent is less than or equal to the preprocessing duration threshold, it means that the duration of overcurrent charging is still relatively short. A relatively conservative strategy can be adopted to try to process it. Therefore, the vehicle request current can be adjusted based on the overcurrent amount to generate a new vehicle request current. Then, return to step S10 to perform negative feedback adjustment on the vehicle request current through the overcurrent amount, try to reduce the vehicle request current, and try to reduce the output current of the charging pile to ensure that overcurrent charging no longer occurs. This process is repeated until charging is complete.

[0043] In practical applications, the overcurrent can be multiplied by a preset adjustment coefficient to generate a current adjustment amount. Then, the difference between the vehicle's requested current and the current adjustment amount is used as the new vehicle's requested current.

[0044] The preset adjustment coefficient can be set in advance by the administrator of the charging control equipment, for example, the preset adjustment coefficient can be set to 1 or 0.8.

[0045] In addition, the preset adjustment coefficient may not be a fixed value, but may be dynamically adjusted according to the value of the overcurrent. For example, the administrator of the charging control equipment may preset multiple overcurrent ranges. Different overcurrent ranges correspond to different preset adjustment coefficients, and the larger the value of the overcurrent range, the larger the corresponding preset adjustment coefficient.

[0046] This embodiment provides a charging control method that, when overcurrent charging is detected during the charging process, does not directly report a fault. Instead, it first attempts to adjust the vehicle's requested current based on the amount of overcurrent to try to reduce the charging pile's output current, thereby eliminating the overcurrent charging situation. This ensures that charging will not be directly interrupted due to overcurrent charging, improving the user's actual experience.

[0047] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in Embodiment 1 above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 After step S20, the charging control method further includes steps S30'~S60': Step S30': If the overcurrent duration is greater than the preprocessing duration threshold and less than or equal to the fault determination duration threshold, then determine the power to be consumed based on the overcurrent amount.

[0048] It should be noted that if the duration of overcurrent is greater than the preprocessing duration threshold but less than or equal to the fault determination duration threshold, it indicates that the duration of overcurrent charging is already quite long, and adjusting the request current cannot eliminate the overcurrent charging situation. This may be because the minimum output current of the charging pile is already large, which will cause the vehicle to overcurrent charge. Based on this, we can try to consume part of the overcurrent current by running the motor in the vehicle. Therefore, the power to be consumed can be determined based on the amount of overcurrent.

[0049] If the duration of overcurrent exceeds the fault determination time threshold, it means that the duration of overcurrent charging has been too long and the overcurrent cannot be consumed by the motor operation. At this time, a fault can be reported and charging can be terminated.

[0050] The power to be consumed can be obtained by multiplying the overcurrent by the current voltage of the motor in the vehicle. For example, assuming the current time is t, the battery current is A', the charging current is A, and the current voltage of the motor is V(t), then the power to be consumed P1 = |A' - A| V(t).

[0051] In practical implementation, to ensure safety, redundant judgments can be added. For example, when the overcurrent duration is greater than the preprocessing duration threshold but less than or equal to the fault determination duration threshold, the vehicle's gear is first checked to see if it is in park (P). Only when it is in park is the power to be consumed determined based on the overcurrent.

[0052] In addition, the duration of overcurrent can be further detected. For example, if the duration of overcurrent is greater than the preprocessing duration threshold but less than or equal to the fault determination duration threshold, the duration of overcurrent can be further detected to see if it is greater than the filtering duration threshold. If it is, the power to be consumed can be determined based on the overcurrent current.

[0053] Among them, the filtering time threshold can be the difference between the fault judgment time threshold and the motor dynamic shunt filtering time. The motor dynamic shunt filtering time can be the dynamically adjusted time window or algorithm response period used by the motor controller (MCU) when performing digital filtering processing on the current sampling signal.

[0054] The two redundant verification actions mentioned above (i.e., parking gear verification and further verification of overcurrent duration) can be selected for inclusion or exclusion based on actual needs (either not included, one or both can be included), and this embodiment does not impose any restrictions on this.

[0055] Step S40': Determine the motor operating power based on the power to be consumed.

[0056] In actual use, if the motor in the vehicle is not running at this time, the power to be consumed can be directly used as the motor's operating power. If the motor in the vehicle is already running, the sum of the current operating power of the motor and the power to be consumed can be used as the operating power of the motor.

[0057] Step S50': Control the motor operation according to the motor operating power and obtain the actual operating power of the motor.

[0058] It should be noted that the motor controller can be a controller that controls the operation of the motor in the vehicle. In this case, the motor operating power can be input into the motor controller, and the motor controller will then cause the motor to stall, and make the actual operating power of the motor when stalled as close as possible to the motor operating power.

[0059] However, in actual control, there will be certain control errors. In order to ensure that the motor can consume the overcurrent, it is necessary to ensure that the actual operating power of the motor is consistent with the power to be consumed as much as possible. Therefore, the actual operating power of the motor can be obtained.

[0060] The actual operating power of the motor can be calculated based on the current and voltage collected in the motor in real time.

[0061] Step S60': If the actual operating power is consistent with the power to be consumed, then return to the step of determining the overcurrent based on the output current of the charging pile or the inflow current of the battery.

[0062] In actual use, if the actual operating power is consistent with the power to be consumed, it means that the overcurrent can be consumed by the operation of the motor. At this time, no further adjustments are needed. Therefore, we can return to step S20 and continue to monitor the overcurrent.

[0063] In a specific implementation, in order to ensure that the motor can dissipate the overcurrent as much as possible, the following step S50' in this embodiment may also include: If the actual operating power is inconsistent with the power to be consumed, then the power difference is determined based on the actual operating power and the power to be consumed. The motor operating power is corrected based on the power difference to generate a new motor operating power, and the process returns to the step of controlling the motor operation based on the motor operating power.

[0064] It should be noted that if the actual operating power is inconsistent with the power to be consumed, it means that due to control error, the actual current consumed by the motor is greater than or less than the overcurrent. In this case, the difference between the actual operating power and the power to be consumed can be used as the power difference. Then, the motor operating power is corrected based on the power difference to generate a new motor operating power. After that, the process returns to step S50' to realize negative feedback adjustment of the motor operating power based on the power difference, so as to ensure that the actual operating power of the motor is consistent with the power to be consumed.

[0065] Specifically, the power difference can be multiplied by a preset adjustment coefficient to obtain the power adjustment value, and the difference between the motor operating power and the power adjustment value can be used as the new motor operating power.

[0066] The preset adjustment coefficient can be set in advance by the administrator of the charging control equipment, for example, the preset adjustment coefficient can be set to 1 or 0.8.

[0067] In addition, the preset adjustment coefficient may not be a fixed value, but may be dynamically adjusted according to the power difference. The setting method is similar to that of the preset adjustment coefficient, and will not be described in detail here.

[0068] This embodiment provides a charging control method. When it is determined that adjusting the vehicle's requested current based on the overcurrent amount cannot eliminate the overcurrent charging, this embodiment determines the power to be consumed based on the overcurrent amount and controls the motor to operate based on the power to be consumed in order to attempt to consume the overcurrent. This avoids excessive current flowing into the battery and causing damage to the battery without interrupting the charging process.

[0069] Based on the first embodiment of this application, in the third embodiment of this application, the same or similar content as the above embodiment can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 3 Step S50' includes steps S501'~S502': S501': Control the motor operation according to the motor operating power and obtain the motor temperature.

[0070] It should be noted that while it is possible to use the motor to dissipate the excess current, it is also necessary to avoid overheating the motor and damaging it. Therefore, the motor temperature can be obtained when controlling the motor operation based on its operating power.

[0071] The motor temperature can be the current temperature value of the motor, which can be obtained through the motor's temperature control system or a temperature sensor installed in the motor.

[0072] Specifically, the motor temperature can be the motor oil temperature, the motor controller temperature, or the motor controller coolant inlet / outlet temperature, or a combination of one or more of these values ​​(such as average, maximum, or minimum values). This embodiment does not limit this.

[0073] S502': If the motor temperature is less than or equal to the over-temperature warning threshold, then obtain the actual operating power of the motor.

[0074] It should be noted that if the motor temperature is less than or equal to the over-temperature warning threshold, it means that the motor temperature is still low. In this case, no additional processing is required, and the actual operating power of the motor can be directly obtained for subsequent judgment.

[0075] Among them, the over-temperature warning threshold can be the difference between the over-temperature fault threshold and the motor pre-over-temperature filter temperature. The over-temperature fault threshold can be the critical temperature at which the motor is prone to damage. The motor pre-over-temperature filter threshold can be the threshold to prevent overcurrent caused by motor pre-over-temperature during the control process.

[0076] Both the over-temperature fault threshold and the motor pre-over-temperature filter temperature can be preset or calibrated by the administrator of the charging control equipment.

[0077] In a specific implementation, to avoid damage to the motor, after step S501' described in this embodiment, the following may also be included: If the motor temperature is greater than the over-temperature warning threshold but less than the over-temperature fault threshold, the motor operating power is reduced to generate a new motor operating power, and the process returns to the steps of controlling the motor operation based on the motor operating power and obtaining the motor temperature.

[0078] It should be noted that if the motor temperature is greater than the over-temperature warning threshold but less than the over-temperature fault threshold, it means that the motor temperature is already high, but has not yet reached the critical point. Therefore, it is possible to try to reduce the motor power to prevent the temperature from continuing to rise. Thus, the motor operating power can be reduced to generate new motor operating power.

[0079] Specifically, the motor operating power can be multiplied by a preset attenuation coefficient, and the product can be used as the new motor operating power.

[0080] The preset attenuation coefficient can be set in advance by the administrator of the charging control equipment, for example, the preset attenuation coefficient can be set to 0.8.

[0081] Of course, the preset attenuation coefficient can also be calculated based on the motor operating power at the previous adjustment and the motor operating power at the current moment. For example, calculate the difference between the motor operating power at the previous adjustment and the motor operating power at the current moment, and use the ratio of this difference to the motor operating power at the current moment as the preset attenuation coefficient.

[0082] In a specific implementation, to avoid damage to the motor, step S40' in this embodiment may include: Determine if the sign prohibiting compensation exists; If not, the motor operating power is determined based on the power to be consumed; Accordingly, after step S501', the following may also be included: If the motor temperature is greater than or equal to the over-temperature fault threshold, the motor is controlled to stop running, a compensation prohibition flag is set, and the process returns to the step of determining whether the compensation prohibition flag exists.

[0083] It should be noted that if the motor temperature is greater than or equal to the over-temperature fault threshold, it means that the motor temperature is already extremely high, and continued operation may pose a risk of damage. It also indicates that the overcurrent may be too large, and the normal operation of the motor cannot consume the overcurrent. Therefore, the motor can be stopped, a compensation prohibition flag can be set, and the process can be returned to the step of checking whether the compensation prohibition flag exists to ensure that the motor is not started again in an attempt to consume the overcurrent.

[0084] This embodiment provides a charging control method. When determining the amount of overcurrent consumed by the motor during operation, this embodiment monitors the motor temperature to avoid damage to the motor due to excessive overcurrent, thereby further improving safety and reliability.

[0085] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the charging control method of this application. Any simple modifications based on this technical concept are within the protection scope of this application.

[0086] This application also provides a charging control device, please refer to...

The determining module 20 is used to determine the overcurrent amount based on the output current of the charging pile or the inflow current of the battery; The control module 30 is used to adjust the vehicle's requested current based on the overcurrent amount if the overcurrent duration is less than or equal to the preprocessing duration threshold, and then return to the steps of requesting charging from the charging pile based on the vehicle's requested current and obtaining the charging pile's output current.
