Description

Technical Field

[0001] The present invention relates to the technical field of range extender loaders, and in particular to a power generation control method and related equipment for a range extender loader. Background Art

[0002] The statements in this part merely provide the background art related to the present invention and do not necessarily constitute the prior art.

[0003] A range-extended electric loader is an electric loader that uses a range extender to replenish electrical energy when the battery power is insufficient. The energy management strategy in a range extender loader (or more generally, a range-extended electric vehicle) is the core of vehicle control and is directly related to the vehicle's fuel economy, power performance, and ability to adapt to complex working conditions. Among them, the fixed-point power generation strategy and the power following strategy are two main range extender energy management strategies.

[0004] Under the fixed-point power generation strategy, the engine outputs power at a constant power at a preset operating point and does not change with the working conditions, which can make the engine operating condition point stable and reliable. However, this may cause the power battery to need to perform high-power charge and discharge frequently to meet the vehicle's power demand, which will over-consume the electrical energy of the power battery and damage the service life of the power battery; under the power following strategy, as much of the vehicle's demand power as possible comes from the range extender, reducing the consumption of the electrical energy of the power battery and extending the service life of the power battery. However, the engine needs to adjust its output power according to the vehicle's real-time demand power, which may cause the engine to work at multiple different power points, and the efficiency of each power point may not be optimal. Especially in low-speed and high-speed working conditions, the efficiency of the engine may be significantly reduced, thus affecting the vehicle's fuel economy and emission performance.

[0005] For example, Chinese Patent CN118894092A discloses a range extender control method, control system, equipment and medium for a range-extended vehicle, which realizes that when the vehicle's power consumption demand changes, the power generation power of the range extender can follow the change by controlling the power generation power of the range extender to follow the vehicle's demand power, so as to keep the available power of the battery pack within a preset range. However, it only simply uses the power following power generation strategy from the perspective of energy management and does not effectively distinguish and control scenarios such as strong transient processes, excessive post-treatment carbon loading, and affecting engine reliability (such as low water temperature or low state of charge of the power battery). Summary of the Invention

[0006] To solve the deficiencies of the prior art, the present invention provides a power generation control method and related equipment for a range extender loader, which combines the advantages of fixed-point power generation and power following.

[0049] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0050] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0051] In the case of no conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0052] Embodiment 1:

[0053] This implementation proposes a power generation control method for a range extender loader. First, the technical terms and related concepts involved in this processing solution will be briefly introduced, where:

[0054] A range extender is a device used in electric vehicles or hybrid vehicles to extend the driving range. It is usually a small internal combustion engine (such as a gasoline engine or a diesel engine) combined with a generator. The main function of the range extender is to charge the battery by generating electricity when the battery power is exhausted, thereby extending the driving distance of the vehicle. The range extender can maintain low fuel consumption and emissions during vehicle operation, enhancing the convenience of using electric vehicles.

[0055] Fixed-point power generation is a power generation method in which the power generation power of the range extender does not change with the power demand of the whole vehicle. The engine operates at a fixed operating point, and the engine speed and torque are constant.

[0056] Power following is a power generation method in which the power generation power of the range extender changes with the power demand of the whole vehicle. The power generation power of the range extender follows the power demand of the whole vehicle, aiming to minimize the charge and discharge losses generated by the electric energy flowing through the power battery.

[0057] The weak power following strategy is a power generation strategy adopted when the external demand power changes relatively smoothly and the internal conditions of the range extender are not good. The characteristic of this strategy is that the response of the power generation amount to the external demand is relatively slow and gentle, and it will not completely follow every subtle change in the external demand. The purpose of doing this is to minimize the negative impact on the operating state of the range extender while ensuring power supply. The weak power following strategy is applicable to scenarios where the range extender is in an unfavorable working state or environmental performance needs to be prioritized.

[0058] The strong power following strategy is a power generation strategy adopted when the external demand power changes smoothly and the internal conditions of the range extender are good (such as low carbon load, moderate water temperature, and normal or high state of charge of the power battery). The characteristic of this strategy is that the power generation amount can closely follow the changes in external demand, quickly respond to the increase and decrease of power demand. The purpose of doing this is to make full use of the power generation potential of the range extender, improve power generation efficiency, and ensure the flexibility and reliability of power supply. The strong power following strategy is applicable to scenarios where the range extender is in the best working state and priority needs to be given to power generation efficiency and response speed.

[0059] Carbon Load refers to the total amount of carbon accumulated in the engine, exhaust system, or other related equipment. This carbon usually comes from incomplete combustion of fuel, evaporation of engine oil, or other chemical reactions. The increase in carbon load will lead to performance degradation, reduced fuel efficiency, increased emissions, and higher maintenance costs.

[0060] Such as Figure 1 And Figure 2 As shown in

[0061] S1: When the change rate of external demand power is greater than the set change rate threshold (i.e., strong transient process), perform fixed-point power generation at the average external demand power .

[0062] Specifically, when the change rate of external demand power is greater than the set change rate threshold , it indicates that the external power demand fluctuates sharply. In order to ensure the stability and response speed of power supply for the range extender loader, choose to perform fixed-point power generation at the average external demand power . By locking the average external demand power for power generation within a period of time, the violent power fluctuations can be effectively smoothed, the impact on the range extender loader caused by frequent adjustment of power generation amount can be reduced, and the stability and continuity of power generation can be ensured.

[0063] S2: When the change rate of external demand power is less than or equal to the set change rate threshold (i.e., weak transient process), if the carbon load is greater than or equal to the carbon load threshold , perform power generation according to the weak power following power generation strategy.

[0064] Specifically, when the external demand power changes relatively smoothly ( ) and the internal carbon load of the range extender is relatively high ( ), a weak power following power generation strategy is adopted to match the changes in external demand by moderately adjusting the power generation, while considering the impact of carbon load on combustion efficiency and emissions. The weak power following power generation strategy aims to balance power generation efficiency, fuel efficiency and environmental protection needs, ensuring that while meeting electricity demand, the emission of harmful substances is reduced.

[0065] S3: If the carbon load is less than the carbon load threshold , the water temperature is lower than the minimum water temperature , based on the external average power demand Implement fixed-point power generation.

[0066] Specifically, if the carbon loading is low ( ) and the water temperature is below the minimum , it is judged that the range extender is in an unfavorable working state. At this time, the average power required by the external Fixed-point power generation is designed to protect the range extender from possible damage caused by frequent adjustments in power generation. At the same time, stable power generation helps maintain the continuity of power supply and ensure the normal operation of the loader.

[0067] S4: If the carbon load is less than the carbon load threshold , the water temperature is higher than or equal to the minimum water temperature (ie water temperature is normal), charge state (State of Charge) value is less than the minimum state of charge , with the maximum external power requirement Perform fixed-point power generation.

[0068] Specifically, when the carbon loading is low and the water temperature is moderate but the state of charge of the power battery is Lower values ( ), select the maximum external power requirement Performing fixed-point power generation to quickly increase the state of charge value, ensuring that the energy storage equipment has sufficient backup capacity to cope with possible peaks in electricity demand. By maximizing power generation, the energy storage equipment can be quickly replenished to ensure the continuous operation of the loader.

[0069] S5: If the carbon load is less than the carbon load threshold , the water temperature is higher than or equal to the minimum water temperature , state of charge value Greater than or equal to the minimum state of charge (i.e. the state of charge is normal), and power generation is carried out according to the power generation strategy of strong power following.

[0070] Specifically, when carbon loading is low, water temperature is moderate, and SOC value is normal or high ( In the case of (), a power-following power generation strategy is adopted, and the power generation amount is adjusted by closely following the changes in external demand, aiming to make full use of the power generation potential of the range extender and improve the power generation efficiency. At the same time, the power-following power generation strategy can ensure the flexibility and response speed of power supply to meet the power demands of the loader under different working conditions.

[0071] In S2 of this implementation method, power generation is carried out according to the weak power-following power generation strategy. At this time, the power generation power is , including:

[0072] S2.1: When the external demand power is within , the power generation power is equal to the external demand power ; It should be noted that here can take the boundary values;

[0073] Specifically, when the external demand power is within , it is considered that the external demand is relatively stable and the range extender has the ability to directly meet these demands without additional adjustment. The power generation power can be directly equal to the external demand power Doing so can maintain the immediacy and accuracy of power supply and reduce unnecessary power generation adjustments at the same time.

[0074] S2.2: When the external demand power is less than , the power generation power is equal to ;

[0075] Specifically, when the external demand power is less than , it is necessary to maintain a certain power generation power to avoid the range extender running frequently in the low-power range, which helps to reduce wear and improve efficiency. By setting the power generation power at , a certain buffer space can be reserved for possible increased demand while ensuring a certain amount of power generation.

[0076] S2.3: When the external demand power is greater than , the power generation power is equal to ; Among them, is the average external demand power, is the minimum external demand power, is the maximum external demand power;

[0077] Specifically, when the external demand power Greater than When it is greater than, it is necessary to maintain a certain upper limit of the power generation power to avoid overloading the range extender. By setting the power generation power at , while meeting most of the requirements, it can prevent damage to the range extender caused by excessive power generation. In addition, this also provides a certain buffer for possible demand fluctuations and can respond more smoothly to changes in external demands.

[0078] In S5 of this implementation method, power generation is carried out according to the power generation strategy of strong power following, including: the power generation power is equal to the external demand power , and the power generation amount is adjusted by closely following the changes in external demands, aiming to make full use of the power generation potential of the range extender and improve the power generation efficiency.
