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 for a range extender loader and related equipment. Background Art

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

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

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

[0005] For example, Chinese patent CN118894092A discloses a range extender control method, control system, device and medium for an extended-range vehicle. The method controls the power generation power of the range extender to change in accordance with the power demand of the vehicle, thereby achieving the change in the power generation power of the range extender when the power demand of the vehicle changes, so as to keep the available power of the battery pack within a preset range. However, the method only uses the power-following power generation strategy from the perspective of energy management, and does not perform effective differentiated control for scenarios such as strong transient processes, excessive post-processing carbon load, and effects on engine reliability (for example, low water temperature or low power battery state of charge value). Summary of the invention

[0006] In order to solve the shortcomings of the prior art, the present invention provides a power generation control method and related equipment for a range extender loader, which integrates the advantages of fixed-point power generation and power following, and adopts fixed-point power generation in strong transient processes; in weak transient processes, when the carbon load is high, weak power following power generation is performed; in weak transient processes, when the carbon load and water temperature are both low, fixed-point power generation is performed; in weak transient processes, when the carbon load is low and the water temperature is normal, fixed-point power generation is performed; in weak transient processes, when the carbon load is low, the water temperature is normal, and the state of charge value is small, fixed-point power generation is performed; in weak transient processes, when the carbon load is low, the water temperature is normal, and the state of charge value is small, fixed-point power generation is performed; in weak transient processes, when the carbon load is low, the water temperature and the state of charge are normal, strong power following power generation is performed, thereby improving the power generation control accuracy of the range extender loader.

[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 descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0051] In the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0052] Embodiment 1:

[0053] This implementation proposes a method for controlling power generation of a range extender loader. The following is a brief introduction to the technical terms and related concepts involved in this solution, including:

[0054] A range extender is a device used to extend the mileage of an electric or hybrid vehicle. 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 is exhausted, thereby extending the vehicle's driving distance. 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 generated by the range extender does not change with the power demand of the vehicle. The engine runs 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 generated by the range extender changes with the power demand of the whole vehicle. The purpose is to minimize the charging and discharging losses caused by the flow of electricity 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 power generation responds relatively slowly and gently to external demand, and will not fully follow every slight change in external demand. The purpose of this is to minimize the negative impact on the operating status of the range extender while ensuring the power supply. The weak power following strategy is suitable for scenarios where the range extender is in an unfavorable working state or where environmental protection 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 loading, moderate water temperature, normal or high state of charge of the power battery). The characteristic of this strategy is that the power generation can closely follow the changes in external demand and quickly respond to the increase or decrease in power demand. The purpose of 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 suitable for scenarios where the range extender is in the best working state and power generation efficiency and response speed need to be prioritized.

[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. An increase in carbon load will lead to decreased performance, reduced fuel efficiency, increased emissions and higher maintenance costs.

[0060] like Figure 1 and Figure 2 As shown, the range extender loader power generation control method includes the following process:

[0061] S1: When the external power demand changes Greater than the set change rate threshold When (i.e. strong transient process), the average power required by the external Perform fixed-point power generation.

[0062] Specifically, when the external power demand change rate Greater than the set change rate threshold When the external power demand fluctuates sharply, in order to ensure the stability and response speed of the range extender loader power supply, the external demand average power is selected. Implement fixed-point power generation by locking in the average power demanded by the external system over a period of time Power generation can effectively smooth out drastic fluctuations in power, reduce the impact on the range extender loader caused by frequent adjustments in power generation, and ensure the stability and continuity of power generation.

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

[0064] Specifically, when the external power demand changes relatively smoothly ( ) and the range extender has a high carbon load ( ), 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 Perform 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 ( ), a strong power following power generation strategy is adopted to adjust the power generation 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 strong power following power generation strategy can ensure the flexibility and response speed of power supply and meet the power demand of the loader under different working conditions.

[0071] In S2 of this implementation, power generation is performed according to the weak power following power generation strategy. At this time, the power generation power is ,include:

[0072] S2.1: When the external power demand exist When within the range, the power generation Equal to external power demand ; It should be noted that here Can take boundary values;

[0073] Specifically, when external power is required lie in Within this range, it is considered that external demand is relatively stable, and the range extender is capable of directly meeting these demands without additional adjustments. Can be directly equal to the external required power Doing so maintains the immediacy and accuracy of power supply while reducing unnecessary generation adjustments.

[0074] S2.2: When the external power demand Less than When the power generation equal ;

[0075] Specifically, when external power is required Less than When the range extender is running at a low power level, it is necessary to maintain a certain power generation capacity to avoid frequent operation of the range extender in the low power range, which helps to reduce wear and improve efficiency. , while ensuring a certain amount of power generation, it also reserves a certain buffer space for possible increase in demand.

[0076] S2.3: When the external power demand Greater than , power generation equal ;in, is the average external power demand, is the minimum external power requirement, is the maximum external power requirement;

[0077] Specifically, when the external power demand Greater than When the power generation capacity is set to a certain level, a certain upper limit of power generation is required to avoid overloading of the range extender. , while meeting most of the demand, it can prevent damage to the range extender due to excessive power generation. In addition, this also provides a certain buffer for possible demand fluctuations and can respond more smoothly to changes in external demand.

[0078] In S5 of this implementation, power generation is performed according to the power generation strategy of strong power following, including: the power generation power is equal to the external demand power , by adjusting power generation closely following changes in external demand, it aims to fully utilize the power generation potential of the range extender and improve power generation efficiency.

[0086] In the weak power follower unit of this implementation, when the external power demand exist When within the range, the power generation Equal to external power demand ; It should be noted that here Can take boundary values;
