Description

Technical Field

[0001] The present disclosure relates to the field of vehicle technology, and in particular to a charging control method, system, extended-range vehicle, and program product. Background Art

[0002] The combination of a range-extended heavy-duty truck and a pure electric heavy-duty truck, known as a "mother-and-child" truck, is a green, low-carbon transportation solution. The mother truck and child truck can each carry cargo to their destination, with the mother truck loading the child truck upon return, saving energy and labor costs. Range-extended heavy-duty trucks can intelligently activate the range extender to recharge their power unit and battery. Pure electric heavy-duty trucks, on the other hand, have the disadvantages of a short single trip distance and the need for fixed charging stations.

[0003] With the rapid development of the new energy heavy-duty truck industry, extended-range and pure electric heavy-duty trucks are gaining increasing market recognition for their superior economic efficiency, with penetration rates increasing year by year. Extended-range heavy-duty trucks can replace traditional heavy-duty trucks in nearly all scenarios, eliminating range anxiety. Pure electric heavy-duty trucks, on the other hand, require fixed charging stations for recharging, and their operating range is often limited by the location of these stations, resulting in a limited operating range. Once a pure electric heavy-duty truck experiences a power outage, it is typically forced to wait for a tow truck, resulting in significant labor, material, and time costs. Summary of the Invention

[0028] Overview

[0029] A Range-Extended Electric Vehicle (REEV) is essentially an electric vehicle equipped with a fuel range extender. This range extender doesn't directly drive the wheels, but instead generates electricity to power the motor or battery when the battery is low, thus addressing the range anxiety of pure electric vehicles.

[0030] In the mother-and-child vehicle combination of an extended-range heavy-duty truck and a pure electric heavy-duty truck, the pure electric vehicle requires a fixed charging pile for energy replenishment. Due to the limited capacity of the power battery and the unpredictability of actual road conditions, the operating range of the pure electric vehicle in actual applications is often limited to the location of the charging pile, and has a limited operating range.

[0031] Based on this, an embodiment of the present disclosure provides a charging control method for an extended-range vehicle to solve the problem that pure electric vehicles are restricted by the location of charging piles and have a limited operating range.

[0032] Exemplary Methods

[0033] The charging control method for extended-range vehicles provided in the embodiments of the present disclosure can be applied to the controller of the extended-range vehicle, which can be a vehicle power domain controller (Power Management System, PMS), or can be applied to other terminals or servers that can communicate with the vehicle or vehicle sensors.

[0034] The present disclosure provides a charging control method for an extended-range vehicle. Figure 1 As shown, the method mainly includes the following steps:

[0035] In step 101, the extended-range vehicle obtains a charging demand power value of a target vehicle.

[0036] For example, in a parent-child vehicle scenario, the range-extended vehicle is the parent vehicle and the target vehicle is the child vehicle. For example, the range-extended vehicle is a range-extended heavy-duty truck parent vehicle, and the target vehicle is a pure electric heavy-duty truck child vehicle. When conditions permit, the range-extended heavy-duty truck parent vehicle charges the pure electric heavy-duty truck child vehicle.

[0037] In addition to being used in scenarios with shuttle buses, it can also be used in other scenarios where pure electric vehicles or other types of vehicles need to be charged.

[0038] It should be noted that the voltage platform of the extended-range vehicle and the target vehicle is the same, for example, both are 400V or 800V voltage platforms.

[0039] In some embodiments, the extended-range vehicle obtains the charging requirement power value of the target vehicle, including: the extended-range vehicle obtains the requested charging power value of the target vehicle; the extended-range vehicle obtains the adjusted power value, and determines the charging requirement power value based on the minimum value of the requested charging power value and the adjusted power value; the adjusted power value is the power value indicated by the power adjustment button.

[0040] In an exemplary embodiment, the minimum value between the requested charging power value and the adjusted power value is used as the required charging power value.

[0041] In an exemplary embodiment, a communication connection is established between the extended-range vehicle and the target vehicle, for example, via a CAN (Controller Area Network) bus. It should be noted that the specific method used to establish the communication connection between the extended-range vehicle and the target vehicle is not limited, and other communication connection methods, such as Bluetooth, may also be used.

[0042] Through the established communication connection, the extended-range vehicle obtains the requested charging power value of the target vehicle.

[0043] In an exemplary embodiment, a power adjustment button is provided in the extended-range vehicle. After obtaining the target vehicle's requested charging power, the extended-range vehicle can display the requested charging power value. Based on the displayed requested charging power value, a person operates the power adjustment button to adjust the power, obtaining the adjusted power value indicated by the power adjustment button. The power range allowed by the power adjustment button is pre-set based on the range extender's capabilities. The extended-range vehicle determines the required charging power value based on the adjusted power value indicated by the power adjustment button and the requested charging power. That is, the required charging power value = min{requested charging power value of the target vehicle, adjusted power value indicated by the power adjustment button of the extended-range vehicle}.

[0044] In some embodiments, the extended-range vehicle obtains the requested charging power value of the target vehicle, including: the target vehicle obtains a first charging power value allowed by the current state of charge (SOC), and obtains a second charging power value allowed by the current battery temperature, and determines the requested charging power value based on the minimum value of the first charging power value and the second charging power value; the extended-range vehicle obtains the requested charging power value from the target vehicle.

[0045] In an exemplary embodiment, the minimum value between the first charging power value and the second charging power value is used as the requested charging power value.

[0046] That is, the requested charging power value of the target vehicle=min{a first charging power value allowed by the current SOC of the target vehicle, a second charging power value allowed by the current battery temperature of the target vehicle}.

[0047] In an exemplary embodiment, a mapping relationship between the SOC and the allowed charging power value is stored in the target vehicle, and the first charging power value corresponding to the current SOC is searched from the mapping relationship.

[0048] In an exemplary embodiment, a mapping relationship between battery temperature and allowed charging power value is stored in the target vehicle, and the second charging power value corresponding to the current battery temperature is searched from the mapping relationship.

[0049] In an exemplary embodiment, the battery management system (BMS) controller of the target vehicle obtains a first charging power value allowed by the current SOC of the target vehicle and a second charging power value allowed by the current battery temperature of the target vehicle, and after determining the requested charging power value of the target vehicle, transmits it to the extended-range vehicle through a communication connection.

[0050] Step 102 : The range-extended vehicle determines a target power generation value based on the required charging power value and a power generation limit parameter of the range extender.

[0051] In some embodiments, the extended-range vehicle determines a target power generation power value based on the charging demand power value and the power generation limit parameter of the range extender, including: the extended-range vehicle determines an upper limit value of power generation power according to the power generation limit parameter of the range extender; the extended-range vehicle determines a target power generation power value based on the minimum value of the upper limit value of power generation power and the charging demand power value.

[0052] In an exemplary embodiment, the extended-range vehicle uses the minimum value of the upper limit of the generated power and the required charging power as the target generated power value.

[0053] In some embodiments, the power generation limit parameters include: a maximum power generation value of the range extender, a first power generation limit value corresponding to the temperature of each component of the range extender, and a second power generation limit value corresponding to the lubricating oil pressure of the range extender.

[0054] The range-extended vehicle determines the upper limit of generated power according to the power generation limit parameter of the range extender, including: the range-extended vehicle determines the upper limit of generated power based on the minimum power value among the maximum generated power value of the range extender, the first generated power limit value, and the second generated power limit value.

[0055] In an exemplary embodiment, the range-extended vehicle uses the minimum power value among the range extender maximum power generation value, the first power generation power limit value, and the second power generation power limit value as the power generation power upper limit value.

[0056] In an exemplary embodiment, the maximum power generation value of the range extender is a pre-calibrated value.

[0057] In an exemplary embodiment, the core components of the range extender include an engine, a permanent magnet synchronous generator, an inverter, etc. Each component is pre-configured with a corresponding power generation limit value at different temperatures. The first power generation limit value corresponding to the temperature of each component of the range extender is obtained based on the configuration.

[0058] In an exemplary embodiment, corresponding power generation limit values ​​are pre-configured when the range extender lubricating oil pressure is in different intervals, and a second power generation limit value corresponding to the range extender lubricating oil pressure is obtained according to the configuration.

[0059] Step 103 : The range-extended vehicle controls the range extender to charge the target vehicle at the target generated power value.

[0060] In some embodiments, before the extended-range vehicle obtains the charging demand power value of the target vehicle, the method further includes: the extended-range vehicle determining that current environmental parameters meet a range extender enabling condition.

[0061] In an exemplary embodiment, when the range extender enabling condition is determined to be met, the range extender enabling flag bit preset value is set to facilitate subsequent determination of whether to control the range extender to charge the target vehicle by reading the value of the range extender enabling flag bit.

[0062] In some embodiments, the range-extended vehicle determines that current environmental parameters satisfy the range-extender enabling condition, including: the range-extended vehicle determines whether the current environmental parameters satisfy the following charging preparatory conditions, and if so, determines that the current environmental parameters satisfy the range-extender enabling condition;

[0063] The charging preparatory conditions include:

[0064] No range extender fault is detected during a current power-on cycle of the range-extended vehicle;

[0065] The external charging function of the extended-range vehicle is in an on state;

[0066] The extended-range vehicle is in a parked state but not shut down;

[0067] The extended-range vehicle has been connected to a plug-in gun;

[0068] The target vehicle is in a charging-allowed state.

[0069] In an exemplary embodiment, the extended-range vehicle is in a parked but not shut-off state as shown in the following aspects: a. The handbrake of the extended-range vehicle is in the pulled-up state; b. The gear position of the extended-range vehicle is neutral; c. The current speed of the extended-range vehicle is ≤3 km / h.

[0070] In an exemplary embodiment, a range-extended vehicle is provided with an on / off button for the external charging function. By operating the on / off button, the external charging function is turned on, and by operating the on / off button again, the external charging function is turned off. The on / off button can be a virtual button displayed on the operation panel or a physical button, and the specific implementation of the button is not limited.

[0071] In an exemplary embodiment, one end of the power plug is inserted into the discharge port of the extended-range vehicle, and the other end is inserted into the charging port of the target vehicle. When the power plug is correctly inserted into the discharge port of the extended-range vehicle, the battery management system (BMS) controller of the extended-range vehicle receives a power plug connection signal. Upon receiving the power plug connection signal, the PMS system of the extended-range vehicle determines that the extended-range vehicle is connected to the power plug. Similarly, when the power plug is correctly inserted into the charging port of the target vehicle, the BMS controller of the target vehicle also receives the power plug connection signal.

[0072] In addition to the power transmission line, the plug also integrates a CAN line. The CAN line in the plug transmits information between the extended-range vehicle and the target vehicle, such as whether the target vehicle is in a charging state or the target vehicle's required charging power value.

[0073] In the exemplary embodiment, the target vehicle is in a charging-permitted state after the target vehicle performs a self-test and is transmitted to the extended-range vehicle. The specific method for generating the target vehicle's charging-permitted state is not limited herein. For example, the target vehicle initiates a self-test after the battery is connected, and after the self-test determines that the battery is fault-free, the target vehicle generates the charging-permitted state information.

[0074] In an exemplary embodiment, the range extender vehicle executes a range extender self-test program during each power-on cycle to detect whether the range extender is faulty. The specific logic of the range extender self-test program is not limited herein.

[0075] In a specific embodiment, Figure 2 The figure shows the process of charging the vehicle by the mother vehicle in the mother-child vehicle application scenario, which mainly includes:

[0076] The mother vehicle determines whether the following charging preparatory conditions are met at the same time: no range extender fault is detected during the current power-on cycle, the external charging function is turned on, the parking brake, gear and speed are determined to be in a parked state without shutting down the engine, the plug is connected, and the child vehicle is in a charging-allowed state; if these charging preparatory conditions are met at the same time, it is determined that the range extender enabling conditions are met.

[0077] The sub-vehicle takes the minimum value between a first charging power value allowed by the current SOC and a second charging power value allowed by the current battery temperature as the requested charging power value.

[0078] The mother vehicle obtains the power value indicated by the power adjustment button, that is, the adjustment power value, and takes the minimum value between the requested charging power value and the adjustment power value as the charging demand power value.

[0079] The mother vehicle takes the minimum value from the maximum power generation value of the range extender, the first power generation limit value corresponding to the temperature of each component of the range extender, and the second power generation limit value corresponding to the lubricating oil pressure of the range extender as the power generation upper limit value.

[0080] The mother vehicle takes the minimum value between the upper limit of the power generation and the required charging power as the target power generation value. The mother vehicle controls the range extender to charge the sub-vehicle at the target power generation value.

[0081] In the disclosed embodiment, the range-extended vehicle obtains the target vehicle's required charging power value; determines a target power generation value based on the required charging power value and the range extender's power generation limit parameters; and controls the range extender to charge the target vehicle at the target power generation value. This method enables the range-extended vehicle to charge the target vehicle using its own range extender, enabling the range-extended mother vehicle to charge a pure electric child vehicle in a parent-child vehicle scenario, resolving the issue of inconvenient child vehicle charging.

[0082] The charging control method implemented at the software level in the embodiment of the present disclosure can quickly generate control logic based on a combination of extended-range mother vehicles of different power and pure electric vehicles of different configurations. It has a wide adaptability, demonstrates high adaptability and a wide range of applications, and achieves significant expansion and optimization of technical applications.

[0083] In addition, the research and development of charging control methods based on PMS can quickly modify control-related parameters, support subjective and objective testing of extended-range mother vehicles of different power and pure electric vehicles of different configurations, improve test efficiency, and make test parameters quantified and controllable, with strong repeatability and high repetition rate, providing good support for the development of the entire vehicle system of mother and child vehicles.
