[0045] In order to make the objectives, technical solutions, and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0046] Range-extended electric vehicles combine a traditional fuel engine and an electric drive system. A small fuel engine is installed as an auxiliary energy source to convert fuel into electrical energy for driving or charging the battery pack.
[0047] Range-extended electric vehicles have a certain pure electric driving range, which is powered by the battery pack and can achieve a pure electric mode for short-distance driving. When parked, in addition to using a charging pile for charging, the range extender can also be used for charging. Therefore, range-extended electric vehicles have more flexible scenario applications compared to pure electric vehicles.
[0048] The charging of the range extender when parked has less dynamic impact compared to the charging of the range extender during driving. Therefore, a fixed power is generally used, but it ignores the needs of the user itself and cannot meet the power generation requirements of the user in different situations.
[0049] The control method for the power generation power of the range extender provided in this application can perform an upward adjustment control on the power generation power of the range extender in response to user control.
[0050] In one embodiment, the control method is as Figure 1 shown and includes the following steps:
[0051] Step 101, obtain a control instruction from the user, where the control instruction is used to indicate that the range extender jumps from a first power generation power to a second power generation power.
[0052] Exemplarily, the user can set to turn on and off the parked power generation mode through the central control large screen IVI (In-Vehicle Infotainment). After the user sets it, the central control large screen IVI will send a corresponding turn-on or turn-off command to the VCU (Vehicle Control Unit).
[0053] After receiving the parked power generation mode turn-on request sent by the IVI, the vehicle control unit VCU will determine whether the vehicle simultaneously meets the following conditions:
[0054] 1) The vehicle speed is less than a certain value (3 km / h, can be calibrated);
[0055] 2) The vehicle is in the parking gear P;
[0056] 3) The vehicle is not in a mode state where the range extender is prohibited from starting or a mode state where the range extender cannot start after setting (such as charging state, discharging state, refueling state, display vehicle state, etc.);
[0057] 4) The vehicle is in a high-voltage state;
[0058] 5) The battery pack power ≤ a certain value (80%, can be calibrated).
[0059] If the condition is met, the vehicle control unit controls the range extender to start and enter the default power generation state. At the same time, it feedbacks to the IVI that the parked power generation mode is turned on. After receiving it, the IVI displays that the parked power generation mode is in the on state; if not met, the vehicle control unit (VCU) continuously sends a trigger request for the failure to turn on the parked power generation mode to the IVI for 2 seconds. After receiving it, the IVI pops up a window to prompt "Failed to turn on the parked power generation mode".
[0060] It can be understood that under the consideration of conditions such as noise, vibration, and the battery pack's reception ability, the default power generation mode is generally the low-power power generation mode, and there is a fixed first power generation power corresponding to the low-power power generation mode.
[0061] The user can adjust the power generation power based on their own needs. Specifically, in this embodiment, after the vehicle turns on the parked power generation mode, the IVI displays a drop-down menu, and the user can select and switch the parked power generation mode state through the drop-down menu. The parked power generation mode state has at least two fixed modes: the default low-power power generation mode and the high-power power generation mode for selection. In the high-power power generation mode, the range extender generates electricity according to a preset fixed and higher second power generation power.
[0062] In some other embodiments, a more flexible setting method can be adopted, such as allowing the user to set the value of the power generation power by themselves. However, generally, the user doesn't have much understanding of the range extender's power generation power, and letting them set the power by themselves increases the user's burden, and it is difficult for the range extender to operate in the most efficient working state when operating according to the power set by the user.
[0063] For the above reasons, the designer can conduct experimental calibration on the second power generation power in the high-power power generation mode to determine the optimal power generation power.
[0064] After the user selects the high-power power generation mode, the central control large screen IVI sends a high-power power generation mode request to the VCU, and the VCU executes the next step.
[0065] Step 102, based on the user's control instruction, obtain the state before power jump, including obtaining the battery pack state and the range extender state.
[0066] The battery pack state includes the battery pack power and the battery pack temperature. According to the battery pack power and the battery pack temperature, determine the extreme value of the allowable charging power of the battery pack from the preset first corresponding relationship.
[0067] Exemplarily, the extreme value of the allowable charging power is the maximum charging power that the battery pack can accept in the current state. When the actual charging power is higher than the extreme value of the allowable charging power, it may have an adverse impact on the battery pack.
[0068] When the vehicle is in a stationary state, the extreme value of the allowable charging power of the battery pack is related to the temperature and the state of charge of the battery pack, and is a two-dimensional function of the state of charge and temperature of the battery pack. Within a certain range of the battery pack temperature, the influence on the extreme value of the allowable charging power of the battery pack is that as the battery pack temperature increases, the extreme value of the allowable charging power becomes larger. After the battery pack temperature exceeds a certain value, the extreme value of the allowable charging power of the battery pack decreases as the temperature increases. The influence of the state of charge of the battery pack on the allowable charging power is that as the state of charge of the battery pack increases, the extreme value of the allowable charging power decreases.
[0069] When conducting charging tests on the battery pack at different temperatures, the charging capabilities of the battery pack at different temperatures and different states of charge are obtained, and the first corresponding relationship between the extreme value of the allowable charging power and the temperature and the state of charge is obtained.
[0070] In some embodiments, the influencing factors of the extreme value of the allowable charging power further include the fault state of the battery pack. During the actual implementation process, a detailed fault diagnosis strategy is formulated for the battery pack to identify the voltage and resistance of each battery cell of the battery pack, as well as the temperature and pressure inside the battery pack. When a fault occurs in the battery pack, the fault level will be reported according to the fault state and the determined fault handling mechanism, and at the same time, the charge and discharge capabilities will be restricted. In case of a serious fault, the high voltage will be controlled to directly stop the charge and discharge. The above information will ultimately be sent out by the battery pack in the form of the extreme value of the charging power to the vehicle control unit VCU.
[0071] When the range extender generates electricity while parked, considering the influence of noise, vibration, etc., the power generation power needs to be restricted in different power modes. The power generation power during parked power generation is not too high, far lower than the rated power generation power of the range extender.
[0072] When the range extender generates electricity while parked, the main factors affecting the power generation ability of the range extender mainly include the temperature of the range extender. Generally, the coolant temperature of the range extender is selected to replace the temperature of the range extender to participate in the logic control. When the coolant temperature of the range extender is relatively high, the power generation power will be restricted. Based on this, power generation tests are conducted at different temperatures to determine the second corresponding relationship between the temperature of the range extender and the extreme value of the allowable power generation power. When needed, the extreme value of the allowable power generation power of the range extender is found and determined from the second corresponding relationship.
[0073] In addition, the extreme value of the power generation power of the range extender is also related to the fault state of the range extender. Similar to the battery pack state, when a fault occurs in the range extender, the fault level will be reported according to the fault state and the determined fault handling mechanism, and at the same time, the power generation ability will be restricted, which is ultimately reflected in the way of reducing the extreme value of the allowable power generation power.
[0074] After the VCU calculates and obtains the extreme value of the allowable charging power and the extreme value of the allowable power generation power, the next step is carried out.
[0075] Step 103, power judgment, and determining a first target power of the range extender according to the judgment result, including: when both the extreme value of the allowable charging power and the extreme value of the allowable power generation are greater than the second power generation power, determining the second power generation power as the first target power, and controlling the range extender to jump to the second power generation power.
[0076] In the above control method for the parked power generation power of the range extender, the range extender can respond to the user's control instruction and jump from a lower first power generation power to a higher second power generation power to meet the user's demand for a higher parked charging power. And when jumping, the capabilities of the battery pack and the range extender are judged, and the jump will only be executed when the capabilities of both meet the user's requirements. Therefore, safety guarantees for the battery pack and the range extender are provided.
[0077] Generally, when either the extreme value of the allowable charging power or the extreme value of the allowable power generation does not meet the jump condition, the power generation power will be maintained at the current level, that is, the first power generation power. On this basis, this application adds a judgment of the transition state. When the capabilities of the battery pack and the range extender meet the transition state, it jumps to the transition state, which to a certain extent meets the user's demand for increasing the power generation power.
[0078] Exemplarily, between the low-power power generation mode and the high-power power generation mode of this application, a medium-power power generation mode is set as a transition. The medium-power power generation mode generates power according to the transition power generation power, that is, the medium power, as Figure 2 shown. When the user issues a control instruction to jump to the high-power power generation mode, first, a judgment ① is made with the second power generation power. If the extreme value of the allowable charging power or the extreme value of the allowable power generation is less than or equal to the second power generation power, then a further judgment ② is made: judging whether both the extreme value of the allowable charging power and the extreme value of the allowable power generation are greater than a preset transition power generation power, where the transition power generation power is greater than the first power generation power and less than the second power generation power.
[0079] If both the extreme value of the allowable charging power and the extreme value of the allowable power generation are greater than the transition power generation power, then determining the transition power generation power as the first target power, and controlling the range extender to jump to the transition power generation power.
[0080] In an implementation manner of the above embodiment, after jumping to the transition mode, the monitoring of the power generation capacity of the range extender and the charging capacity of the battery pack is maintained, so that when the power generation capacity and the charging capacity are met, the power generation power can be continuously adjusted to the first power generation power expected by the user. Specifically:
[0081] As Figure 3As shown, the VCU monitors the battery pack power, battery pack temperature, and range extender status in real time, and also looks up and obtains the real-time value of the allowable charging power and the real-time value of the allowable power generation according to the first correspondence and the second correspondence, and makes a judgment ③ based on the real-time value of the allowable charging power and the real-time value of the allowable power generation to determine the second target power for the next jump of the range extender.
[0082] When both the real-time value of the allowable charging power and the real-time value of the allowable power generation are greater than the second power generation power, determine the second power generation power as the second target power, and control the range extender to jump to the second power generation power.
[0083] In addition, during the continuous monitoring process, it may also be due to the decrease in the power generation capacity or charging capacity that causes the power generation power to jump to a lower state, such as Figure 4 As shown, when the first target power is the transition power generation power, if either the real-time value of the allowable charging power or the real-time value of the allowable power generation is less than or equal to the transition power generation power, determine the first power generation power as the second target power.
[0084] Or as Figure 5 As shown, when the first target power is the second power generation power, if either the real-time value of the allowable charging power or the real-time value of the allowable power generation is less than or equal to the second power generation power and both are greater than the transition power generation power, determine the transition power generation power as the second target power.
[0085] The control method for the parked power generation power of the range extender provided by this application is a control method based on user feedback. When the power generation capacity of the range extender or the charging capacity of the battery pack does not meet the user's expectations and the desired state jump cannot be executed, a prompt strategy will be executed, and the corresponding state jump will be executed according to the user's feedback. For example:
[0086] When the VCU receives an IVI request to enter high-power power generation in low-power mode, it makes a comprehensive judgment based on the extreme values of the allowed charging power and the allowed power generation power. If both are higher than the power generation power of the high-power power generation mode, it directly responds to the IVI request, feedbacks the high-power power generation mode to the IVI, and controls the range extender to enter the high-power power generation mode. Otherwise, the VCU will maintain the current low-power power generation mode and determine whether both are higher than the power generation power of the medium-power power generation mode. If so, a pop-up window will prompt the notification that the current power generation capacity is unexpected: "The current maximum allowed charging power is medium power. Do you want to switch?" If the user selects "OK", it will feedback the medium-power power generation mode to the IVI and control the range extender to enter the medium-power power generation mode. If the user selects "NO" and still hopes to jump from the low-power power generation mode to the high-power power generation mode, it will feedback the medium-power power generation mode to the IVI, control the range extender to enter the medium-power power generation mode, and simultaneously pop up a window to prompt the user "The current power generation power is temporarily switched to medium power, waiting for switching". At the same time, the VCU will continuously monitor the allowed charging power and the maximum allowed power generation power of the range extender. After both powers are higher than the power generation power (high power) selected by the user, it will automatically switch to the high-power power generation mode, and simultaneously pop up a window to prompt the user "The current power generation mode has been switched to the high-power mode".
[0087] In some embodiments, the medium-power power generation mode is a mode that can be selected by the user. When the VCU receives an IVI request to enter medium-power power generation in low-power power generation mode, it makes a comprehensive judgment based on the battery pack capacity and the range extender capacity. If the extreme values of the allowed charging power and the allowed power generation power are both higher than the power generation power of the medium-power power generation mode, it directly responds to the IVI request, feedbacks the medium-power generation power mode to the IVI, and controls the range extender to enter the medium-power power generation mode. Otherwise, the VCU will maintain the current low-power power generation mode and send a power generation power status prompt as a request to the IVI. After receiving it, the IVI will pop up a window to prompt "The current maximum allowed charging power is low power. Do you want to maintain the current low-power mode?" If the user selects "OK", it will continue to maintain the current low-power power generation. If the user selects "NO", it will maintain the current low-power power generation mode, and simultaneously continuously judge the real-time value of the allowed charging power and the real-time value of the allowed power generation power. After both powers are higher than the power generation power (medium power) selected by the user, it will automatically switch to the medium-power power generation mode, and simultaneously pop up a window to prompt the user "The current power generation mode has been switched to the medium-power mode".
[0088] The user can select to turn off the parked vehicle power generation mode through the central control large screen IVI. The IVI will send a shutdown request to the VCU. After receiving it, the VCU will feedback that the parked vehicle power generation mode is turned off and control the range extender to stop.
[0089] In the parked vehicle power generation mode, if the vehicle control unit detects that any of the following conditions is met, it will send the parked vehicle power generation mode off status to the IVI and simultaneously control the engine to stop:
[0090] 1) The vehicle speed of the whole vehicle is greater than a certain value (3 km / h, which can be calibrated);
[0091] 2) The vehicle is in the driving gear D or R;
[0092] 3) The vehicle enters a mode state with a higher priority than the emission detection mode and prohibits the range extender from starting after entering (such as the charging state of the charging pile, the refueling state, the display vehicle state, etc.);
[0093] 4) The vehicle is in the high-voltage power-off state;
[0094] 5) The battery pack power is greater than a certain value, such as 82%.
[0095] After the parked power generation is ended, the user settings can be stored, and when the parked power generation mode is turned on again in the next power-on cycle, the power generation power mode set by the user before is maintained.
[0096] It should be understood that although Figure 1 each step in the flowchart of Figure 1 is shown in sequence according to the indication of the arrow, these steps are not necessarily executed in the order indicated by the arrow. Unless there is a clear description in this article, the execution of these steps has no strict order limit, and these steps can be executed in other orders. Moreover,
[0097] In one embodiment, as Figure 6 shown, a control device for the parked power generation power of the range extender is provided, including: an operation module 201, a state acquisition module 202, a judgment module 203, and an execution module 204, wherein:
[0098] The operation module 201 is used to obtain a control instruction of the user, and the control instruction is used to instruct the range extender to jump from the first power generation power to the second power generation power, and the second power generation power is greater than the first power generation power;
[0099] The state acquisition module 202 is used to determine the extreme value of the allowable charging power of the battery pack from a preset first correspondence according to the battery pack power and the battery pack temperature; and determine the extreme value of the allowable power generation power of the range extender from a preset second correspondence according to the range extender state, and the range extender state at least includes the range extender temperature;
[0100] A judgment module 203, configured to perform power judgment and determine a first target power of the range extender according to a judgment result, including: when both the extreme value of the allowable charging power and the extreme value of the allowable power generation are greater than the second power generation power, determining the second power generation power as the first target power;
[0101] An execution module 204, configured to control the range extender to jump to the second power generation power.
[0102] By using the above control device for the parked power generation power of the range extender, after receiving a control instruction for increasing the power generation power issued by the user, the power is judged, including judging based on the charging power of the battery pack and judging based on the power generation power of the range extender. When both meet the second power generation power expected by the user, the range extender can be controlled to operate at the second power generation power, achieving the purpose of the user increasing the power generation power to adapt to more scenarios.
[0103] In one embodiment, the judgment module 203 is further configured to, when the extreme value of the allowable charging power or the extreme value of the allowable power generation is less than or equal to the second power generation power, further judge whether both the extreme value of the allowable charging power and the extreme value of the allowable power generation are greater than a preset transition power generation power. If so, determining the transition power generation power as the first target power, and the execution module 204 controls the range extender to jump to the transition power generation power.
[0104] By using the transition power generation power method, when the user's needs cannot be fully met immediately, a part of the user's needs can be met as much as possible. And in some embodiments, the state acquisition module 202 also monitors the battery pack state and the range extender state in real time, obtains the real-time value of the allowable charging power and the real-time value of the allowable power generation. When the judgment module 203 judges that the real-time value of the allowable charging power and the real-time value of the allowable power generation are greater than the second power generation power again, the execution module 204 controls the range extender to jump to the second power generation power again to fully meet the user's needs.
[0105] When the state acquisition module 202 monitors the battery pack state and the range extender state in real time, if the judgment module 203 judges that any one of the real-time value of the allowable charging power and the real-time value of the allowable power generation is less than the power generation power required by the current state, the execution module 204 can jump the range extender to a state with a smaller power.
[0106] The operation module 201 includes a display unit, configured to perform a notification display of unexpected current power generation capacity when the power generation power expected by the user cannot be met, so as to obtain a first confirmation operation based on the notification display. The first confirmation operation is used to instruct the range extender to jump from the first power generation power to the transition power generation power. After obtaining the first confirmation operation, the execution module 204 can jump the power generation power to the transition power generation power.
