Description

Technical Field

[0001] This invention relates to the field of power generation control technology, and more specifically to a power generation control method, device, storage medium, and vehicle. Background Technology

[0002] In vehicles using small-capacity power batteries, the battery capacity is too small to support prolonged energy absorption or replenishment. When the generator cannot quickly follow changes in drive power, the charging and discharging capabilities of the power battery can be used to replenish and absorb electrical energy, ensuring the vehicle's driving response capability. Currently, generator power generation is generally controlled by following the average load power and adjusting the power generation based on the state of charge (SOC).

[0003] However, this method, which uses deep charging and discharging of the battery to smooth out peak loads, has a limited capacity for small-capacity power batteries, resulting in a limited amount of charge that can be compensated or absorbed. This makes it impossible to achieve long-term and significant peak shaving and valley filling for high-power devices. Furthermore, the power of the drive motor is calculated using DC voltage and DC current, but the current accuracy has a large margin of error. Additionally, the inconsistent message cycles and transmission times of various electrical components lead to low accuracy in the real-time power output of the drive motor. Therefore, with the above solution, the generated power cannot accurately follow the drive power, resulting in continuous discharging or charging of the power battery. For small-capacity batteries, the State of Charge (SOC) will change rapidly, making them more prone to overcharging or over-discharging, leading to shortened battery life or even direct damage.

[0004] Therefore, in the existing power generation control schemes for generators, the generator's power output is difficult to keep up with the vehicle's power consumption. The following effect of power output and power consumption is poor, making it difficult to adjust the SOC of the power battery within a reasonable range, and easily leading to overcharging or over-discharging of the battery. Summary of the Invention

[0005] The purpose of this invention is to provide a power generation control method, device, storage medium, and vehicle to solve the problem of poor tracking effect between the power generation of the generator and the power consumption of the vehicle in the prior art.

[0006] To achieve the above objectives, a first aspect of the present invention provides a power generation control method, comprising:

[0007] Obtain the real-time current value of the power battery;

[0008] The average current value within a preset time period prior to the current moment is determined based on the acquired real-time current value.

[0009] Obtain the current SOC value of the power battery;

[0010] Adjust the generator's output power based on the current SOC value and average current value.

[0011] In this embodiment of the invention, adjusting the generator's power output based on the current SOC value and average current value includes: determining the current power output level adjustment amount of the generator based on the current SOC value and average current value; determining the current power output of the generator based on the current power output level adjustment amount, a preset reference level power, and the generator's power output at the previous moment; and controlling the generator to operate at the current power output.

[0012] In this embodiment of the invention, determining the current power generation level adjustment amount of the generator based on the current SOC value and the average current value includes: determining the SOC interval and current interval where the current SOC value and the average current value are respectively located, wherein the current interval is one of the preset current intervals divided based on the maximum charging current value and the maximum discharging current value of the power battery; traversing the power generation level adjustment table to obtain a preset power generation level adjustment amount that matches the SOC interval and the current interval; and determining the matched preset power generation level adjustment amount as the current power generation level adjustment amount.

[0013] In this embodiment of the invention, the power generation level adjustment table is used to characterize the relationship between any preset current range and any preset SOC range and the preset power generation level adjustment amount. The preset current range includes at least one charging current value range, a zero current range, and at least one discharging current value range. The preset power generation level adjustment amount includes a preset power generation level increase and a preset power generation level decrease. The preset SOC range with a larger charging current value and a larger SOC corresponds to a larger preset power generation level decrease. The preset SOC range with a larger discharging current value and a smaller SOC corresponds to a larger preset power generation level increase. The preset SOC range with a smaller SOC under the zero current range corresponds to a larger preset power generation level increase.

[0014] In this embodiment of the invention, determining the generator's power generation at the current moment based on the current power generation level adjustment amount, the preset benchmark level power, and the generator's power generation at the previous moment includes: determining the adjustment power for the generator based on the current power generation level adjustment amount and the preset benchmark level power; and determining the generator's power generation at the current moment based on the adjustment power and the generator's power generation at the previous moment.

[0015] In this embodiment of the invention, determining the adjustment power for the generator based on the current power generation level adjustment amount and the preset benchmark level power includes: determining the adjustment power as the product between the current power generation level adjustment amount and the preset benchmark level power.

[0016] In this embodiment of the invention, determining the current power generation of the generator based on the adjusted power and the generator's power generation at the previous moment includes: determining the sum between the adjusted power and the generator's power generation at the previous moment as the current power generation.

[0017] A second aspect of the present invention provides a power generation control device, comprising:

[0018] The memory is configured to store instructions;

[0019] The controller is configured to retrieve instructions from memory and, when executing the instructions, to implement the aforementioned power generation control method.

[0020] A third aspect of the present invention provides a machine-readable storage medium storing instructions that, when executed by a processor, configure the processor to perform the power generation control method described above.

[0021] A fourth aspect of the present invention provides a vehicle comprising:

[0022] Power batteries are used to store electrical energy;

[0023] A current sensor is installed on the positive or negative terminal of a power battery to detect the charging and discharging current of the power battery.

[0025] A generator is used to provide electrical energy;

[0026] At least one drive motor is used to consume electrical energy;

[0027] The aforementioned power generation control device.

[0028] The above technical solution assesses the relationship between the generator's current power output and the vehicle's power consumption based on the real-time current of the power battery. It accurately identifies the deviation between the generator's power output and the vehicle's power consumption based on the power battery's current SOC value and average current value, and dynamically adjusts the generator's power output to better match the vehicle's power consumption. This keeps the power battery's SOC within a reasonable range and prevents overcharging and over-discharging of the power battery.

[0038] Figure 1 A schematic flowchart of a power generation control method according to an embodiment of the present invention is shown. Figure 1 As shown, in one embodiment of the present invention, a power generation control method is provided, comprising the following steps:

[0039] Step 101: Obtain the real-time current value of the power battery.

[0040] The vehicle may include a generator and a power battery. The generator converts mechanical energy into electrical energy to provide power. When the generator's output power exceeds the power consumption of the vehicle's drive motor, the generator can provide power to both the drive motor and the power battery, with the power battery charging and storing excess energy. When the generator's output power is less than the drive motor's power consumption, the generator provides power to the drive motor, while the power battery discharges to replenish the drive motor's power.

[0041] The vehicle may also include a current sensor. The current sensor can be installed at either the positive or negative terminal of the power battery. This current sensor can collect the real-time current value of the power battery. During power generation control, the controller can obtain the real-time current value of the power battery through this current sensor. Specifically, when the power battery is charging, the real-time current value can be the real-time charging current value. When the power battery is discharging, the real-time current value can be the real-time discharging current value.

[0042] In one embodiment, to improve the sampling accuracy of the current value, the current sensor installed on the power battery can be a high-precision DC current sensor.

[0043] In one embodiment, to improve the real-time sampling performance of the current value, the electrical signal of the current sensor can be connected to the I / O pin of the controller.

[0044] The vehicles in this embodiment include traditional vehicles as well as new energy vehicles applied in the new energy field, such as range-extended electric vehicles and hybrid vehicles. In addition, the vehicles in this embodiment are also intelligent connected vehicles, which may include sensing / perception systems, communication systems, etc. The in-vehicle sensing / perception system collects vehicle operation data and information about the vehicle's surrounding environment, and the communication system enables network connection with other vehicles and the cloud. The collected vehicle operation data and information about the vehicle's surrounding environment are shared with the cloud and other authorized vehicles to achieve data sharing, remote analysis, intelligent driving and other operations.

[0045] Step 102: Determine the average current value within the preset time period before the current moment based on the acquired real-time current value.

[0046] The processor can determine the average current value over a preset time period prior to the current moment based on the acquired real-time current value. Specifically, it can average all real-time current values ​​over the preset time period to obtain the average current value over the preset time period. The preset time period can be customized according to actual needs.

[0047] In one embodiment, the average current value over a preset time period is determined by the following formula:

[0048]

[0049] Where I refers to the average current value within a preset time period, I k It refers to the k-th real-time current value within a preset time period, and N refers to the total number of real-time current values ​​within the preset time period.

[0050] Step 103: Obtain the current SOC value of the power battery.

[0051] Step 104: Adjust the generator's power output based on the current SOC value and average current value.

[0052] The processor can obtain the current SOC value of the power battery. SOC refers to the state of charge. The processor can adjust the generator's output power based on the current SOC value and the average current value. For example, if the current SOC value is low, the power battery has a low charge level, and the average current value indicates a higher discharge rate; in this case, the generator's output power can be adjusted to be higher. Conversely, if the current SOC value is high, the power battery has a high charge level, and the average current value indicates a higher charge rate; in this case, the generator's output power can be adjusted to be lower.

[0053] In this embodiment of the invention, adjusting the generator's power output based on the current SOC value and average current value includes: determining the current power output level adjustment amount of the generator based on the current SOC value and average current value; determining the current power output of the generator based on the current power output level adjustment amount, a preset reference level power, and the generator's power output at the previous moment; and controlling the generator to operate at the current power output.

[0054] The controller can determine the current generation level adjustment of the generator based on the current SOC value and average current value. The current generation level adjustment refers to the number of levels that the generation level needs to be increased or decreased at the current moment.

[0055] In this embodiment of the invention, determining the current power generation level adjustment amount of the generator based on the current SOC value and the average current value includes: determining the SOC interval and current interval where the current SOC value and the average current value are respectively located, wherein the current interval is one of the preset current intervals divided based on the maximum charging current value and the maximum discharging current value of the power battery; traversing the power generation level adjustment table to obtain a preset power generation level adjustment amount that matches the SOC interval and the current interval; and determining the matched preset power generation level adjustment amount as the current power generation level adjustment amount.

[0056] The controller can acquire the maximum charging current and maximum discharging current of the power battery, and can divide the current range into multiple preset intervals, from the maximum charging current to the maximum discharging current. For example, the maximum charging current is -I.max Maximum discharge current +I max Multiple preset current ranges can be obtained, which can be specifically represented by X1 to X10. Among them, preset current range X1 to preset current range X4 is the charging segment, and the charging current gradually decreases. Preset current range X5 is the zero current segment. Preset current range X6 to preset current range X10 is the discharging segment, and the discharging current gradually increases.

[0057] The controller can obtain the SOC range of the power battery and divide the SOC range into multiple preset SOC intervals. For example, if the SOC range is 0 to 100, multiple preset SOC intervals can be obtained. These multiple preset SOC intervals can be specifically represented by Y1 to Y4. Among them, the SOC value of preset SOC interval Y1 is the lowest, and the SOC value of preset SOC interval Y4 is the highest. The SOC values ​​increase sequentially from preset SOC interval Y1 to preset SOC interval Y4.

[0058] After determining the current SOC value and average current value of the power battery, the controller can determine the SOC range corresponding to the current SOC value from multiple preset current ranges, and the current range corresponding to the average current value from multiple preset current ranges. The controller can then determine whether the current power generation is reasonable based on the SOC range and current range in which the current SOC value and average current value are located, and adjust the current power generation level accordingly.

[0059] Specifically, the controller can iterate through the power generation level adjustment table to obtain a preset SOC range that matches the SOC range and a preset current range that matches the current range, thereby matching a preset power generation level adjustment amount that matches the SOC range and the current range. The controller can then determine the matched preset power generation level adjustment amount as the current power generation level adjustment amount for the generator.

[0060] The above power generation level adjustment table can be constructed based on the following methods: (1) When the power battery is discharging, increase the power generation level. The larger the discharge current of the power battery, the greater the increase in the power generation level; the smaller the discharge current of the power battery, the smaller the increase in the power generation level; when the discharge current of the power battery is in the zero range or close to the zero range, no power generation level adjustment is made; (2) When the power battery is charging, decrease the power generation level. The larger the charging current of the power battery, the greater the decrease in the power generation level; the smaller the charging current of the power battery, the smaller the decrease in the power generation level; when the charging current of the power battery is in the zero range or close to the zero range, no power generation level adjustment is made; (3) When the current of the power batteries is the same but the SOC value of the power batteries is different, the power generation level is compensated according to the SOC state. When the SOC value of the power battery is low, the power generation level adjustment should be appropriately increased. When the SOC value of the power battery is high, the power generation level adjustment should be appropriately decreased.

[0061] In this embodiment of the invention, the power generation level adjustment table is used to characterize the relationship between any preset current range and any preset SOC range and the preset power generation level adjustment amount. The preset current range includes at least one charging current value range, a zero current range, and at least one discharging current value range. The preset power generation level adjustment amount includes a preset power generation level increase and a preset power generation level decrease. The preset SOC range with a larger charging current value and a larger SOC corresponds to a larger preset power generation level decrease. The preset SOC range with a larger discharging current value and a smaller SOC corresponds to a larger preset power generation level increase. The preset SOC range with a smaller SOC under the zero current range corresponds to a larger preset power generation level increase.

[0062] For example, Table 1 below illustrates a power generation level adjustment table. The positive (+) and negative (-) values ​​of the preset power generation level adjustment amount K represent the adjustment direction; a positive K value indicates an increase in the power generation level, and a negative K value indicates a decrease in the power generation level.

[0063] Table 1

[0064]

[0065] The controller can determine the current generating power of the generator based on the current generation level adjustment, the preset reference level power, and the generator's generating power at the previous moment. The preset reference level power refers to the reference power set for each increase or decrease in generation level. The controller can then control the generator to operate at the current generating power.

[0066] In this embodiment of the invention, determining the generator's power generation at the current moment based on the current power generation level adjustment amount, the preset benchmark level power, and the generator's power generation at the previous moment includes: determining the adjustment power for the generator based on the current power generation level adjustment amount and the preset benchmark level power; and determining the generator's power generation at the current moment based on the adjustment power and the generator's power generation at the previous moment.

[0067] The controller can determine the adjustment power for the generator based on the current power generation level adjustment amount and a preset reference level power. Specifically, in this embodiment of the invention, determining the adjustment power for the generator based on the current power generation level adjustment amount and the preset reference level power includes: determining the adjustment power as the product between the current power generation level adjustment amount and the preset reference level power. The controller can determine the product between the current power generation level adjustment amount and the preset reference level power, and determine this product as the adjustment power of the generator at the current moment.

[0068] In one embodiment, the adjusted power for the generator is determined by the following formula:

[0069] P deta =P0*K

[0070] Among them, P deta P0 is the adjusted power of the generator, P0 is the preset base level power, and K is the generator level adjustment amount at time t.

[0071] The controller can determine the generator's current power output based on the adjusted power and the generator's power output at the previous moment. Specifically, in this embodiment of the invention, determining the generator's current power output based on the adjusted power and the generator's power output at the previous moment includes: determining the sum of the adjusted power and the generator's power output at the previous moment as the current power output.

[0072] The controller can obtain the generator's power output at the previous moment, and sum the generator's adjusted power output with the generator's power output at the previous moment. The sum of the adjusted power output and the generator's power output at the previous moment is determined as the current power output.

[0073] In one embodiment, the generator's power output at the current moment is determined by the following formula:

[0074] P t =P deta +P t-1

[0075] Among them, P t P refers to the generator's output power at the current moment. t-1 P represents the generator's output power at the previous moment. deta This refers to the adjusted power of the generator.

[0076] like Figure 2 As shown, a flowchart of another power generation control method is provided.

[0077] During power generation control, the controller acquires real-time current and calculates its average value over a period of time. The controller also acquires the State of Charge (SOC) of the power battery and determines the power generation adjustment level based on the SOC and the average current. Subsequently, it determines the power generation adjustment power based on the adjustment level, determines the generator's power output at the current moment based on the adjustment power, and generates a corresponding power generation request to the generator so that the generator operates at the corresponding power output.

[0078] The above technical solution assesses the relationship between the generator's current power output and the vehicle's power consumption based on the real-time current of the power battery. It accurately identifies the deviation between the generator's power output and the vehicle's power consumption based on the power battery's current SOC value and average current value, and dynamically adjusts the generator's power output to better match the vehicle's power consumption. This keeps the power battery's SOC within a reasonable range and prevents overcharging and over-discharging of the power battery.

[0079] Figure 1 and 2 This is a flowchart illustrating a power generation control method in one embodiment. It should be understood that, although... Figure 1 and 2 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise explicitly stated herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 1 and 2 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

[0080] In one embodiment, a power generation control device is provided, comprising:

When the power battery is discharging, the real-time current value may be the real-time discharging current value.

[0093] The engine drives the generator to produce electricity. When the generator's output power exceeds the power consumption of the vehicle's drive motor, the generator provides electrical energy to both the drive motor and the battery, and the battery charges, absorbing and storing excess energy.

The energy management controller controls the generator's output power by regulating its torque. The drive motor, as an electrical device, responds to driving demands, drives the entire machine, and consumes electrical energy.

[0098] A high-precision current sensor can collect the current of the power battery. The energy management controller can obtain the current and SOC of the power battery, and adjust the power generation of the generator according to the current and SOC of the power battery. This controls the generator to operate at the adjusted power generation capacity, ensuring that the power generation capacity matches the power consumption, and regulating the battery SOC within a reasonable range to prevent overcharging and over-discharging of the battery.
