Description

Technical Field

[0001] This application relates to methods and systems for power control, and more particularly to a power system and energy-saving method. Background Technology

[0002] Currently, with the increasing number of new energy vehicles on the market, driving range has always been a key focus, especially control strategies when the battery is low. The lack of guidance on low battery warnings and control strategies to limit the power-saving mode of the vehicle's auxiliary drive system increases the likelihood of vehicles breaking down due to inability to charge in time. More seriously, a sudden power outage can cause the vehicle to be parked far from a charging station, resulting in unnecessary trouble or even accidents. Furthermore, the operation of other devices inside the car can significantly impact battery consumption; for example, in winter, using the heater can severely reduce the vehicle's driving range.

[0003] Currently, methods to improve driving range include developing an ECO (energy-saving) mode to reduce energy loss during vehicle operation, or developing an energy-saving mode for the air conditioning system to reduce energy loss during vehicle operation. However, only one energy-saving mode can be selected and applied during a vehicle's journey, and the energy-saving design is limited, resulting in limited energy-saving effects.

[0045] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0046] As mentioned earlier, methods to improve driving range include developing an ECO (energy-saving) mode to reduce energy loss during vehicle operation, or developing an energy-saving mode for the air conditioning system to reduce energy loss during vehicle operation. However, the inventors discovered that using only one energy-saving mode for a single driving period means the vehicle cannot automatically switch energy-saving modes when actual conditions change, such as battery depletion or air conditioning activation / deactivation. Such a single energy-saving design has limited energy-saving effectiveness.

[0047] To address this issue, embodiments of this application provide an energy-saving method and apparatus for a power system. When executing this method, the vehicle's operating mode, air conditioning status, and current battery level are acquired. Based on the air conditioning status, vehicle operating mode, whether the air conditioning is in energy-saving mode, and the vehicle's battery level, the vehicle's air conditioning energy-saving mode or operating energy-saving mode is adjusted. This achieves an interactive relationship between the power system's energy-saving mode and the air conditioning's energy-saving mode. When the vehicle's battery level or air conditioning operation changes, the appropriate energy-saving mode can be selected based on the vehicle's current situation. Compared to the existing rigid selection of a single energy-saving mode, this energy-saving selection method is more flexible and can more effectively achieve energy savings by considering the vehicle's operating conditions, thereby improving driving range.

[0048] The method provided in this application is executed by a controller, which can control various devices in the system, such as a vehicle operation module, an air conditioning operation module, a display, and a mode switching module. The controller can determine whether the vehicle's air conditioning is on, and then determine whether the air conditioning operation mode is heating or cooling, selecting different battery power thresholds based on the different air conditioning modes. Furthermore, during mode switching, a pop-up window can be displayed to the user terminal, such as the vehicle's display screen, asking whether to switch to air conditioning energy-saving mode or power-saving mode.

[0049] The following embodiment illustrates the energy-saving method for the power system provided in this application. Please refer to... Figure 1 , Figure 1 A flowchart illustrating a method for energy saving in a power system provided in this application embodiment includes:

[0050] S101: Obtain the vehicle's first operating mode, the vehicle's air conditioning status, and the first battery level.

[0051] The first operating mode is the current power mode of the vehicle. The controller can determine the current power mode of the vehicle, such as power-saving mode or normal operating mode.

[0052] The air conditioner status is used to indicate whether the air conditioner is on or off, and the controller determines whether the air conditioner is currently on or off.

[0053] The first charge level refers to the remaining charge in the vehicle's battery.

[0054] S102: Based on the air conditioning status, the first power level, and the first operating mode, adjust the vehicle to air conditioning energy-saving mode and / or power energy-saving mode.

[0055] Based on the information obtained in step S101, including whether the air conditioning is on, the remaining battery power, and the current vehicle operating status, the appropriate energy-saving mode for the vehicle is determined. This energy-saving mode can be either an air conditioning energy-saving mode or a power-saving mode. Detailed procedures for adjusting vehicle conditions and modes are not elaborated here; please refer to the embodiments described later.

[0056] The energy-saving method for the power system provided in the embodiments of this application will be described in detail below. See also Figure 2 As shown, Figure 2 Another schematic flowchart of the energy-saving method for the power system provided in this application embodiment is shown below. The specific process is as follows:

[0057] S201: Obtain the vehicle's first operating mode, the vehicle's air conditioning status, and the first battery level.

[0058] The first operating mode is the current power mode of the vehicle, the air conditioning status is used to indicate whether the air conditioning is on or off, and the first battery level is the remaining battery level in the vehicle.

[0059] S202: In response to the air conditioner being in a closed state, the first operating mode being a non-power energy-saving mode, and the first power consumption being less than a second limit, the first operating mode is adjusted to the power energy-saving mode.

[0060] Specifically, after the vehicle starts, the controller first checks whether the air conditioning is on. If it is not on, the controller checks whether the vehicle's power ECO mode is on. If it is on, the vehicle maintains its current power. If it is not on, the controller checks whether the current battery remaining charge SOC ≥ 30% (second limit). If it is not on, the controller assumes that the vehicle's battery is low and needs to enter energy-saving mode to improve the vehicle's range, so as to avoid the vehicle having to drive until it reaches a charging station or to ensure that there is still some battery remaining before the next charge.

[0061] In real-world applications, if the SOC ≥ 30% condition is not met, the controller will display a pop-up window on the HUT asking whether the vehicle's power mode should be switched to ECO mode. If the user selects no, the user's choice will be respected, and the vehicle will continue to operate in the current power mode. If the user selects yes, the default strategy is correct, and the power mode will be switched to ECO mode to ensure a longer driving range.

[0062] The energy-saving method for the power system provided in the embodiments of this application will be described in detail below. See also Figure 3 As shown, Figure 3 This is another schematic diagram illustrating the energy-saving process of the power system provided in this application embodiment. The specific process is as follows:

[0063] S301: Obtain the first operating mode of the first vehicle, the air conditioning status of the first vehicle, and the first battery level.

[0064] Obtain the current status of the vehicle.

[0065] S302: In response to the air conditioner being in an on state, the first operating mode being a non-power energy-saving mode, the air conditioner being in an air conditioner energy-saving mode, and the first power consumption being less than a second limit, the first operating mode is adjusted to the power energy-saving mode.

[0066] Specifically, the system obtains the current vehicle air conditioning status and determines whether the air conditioning is on. If the air conditioning is already on, it determines whether the current vehicle operating mode is in power-efficient ECO mode. If the current vehicle is not in power-efficient mode, it determines whether the air conditioning is in energy-efficient mode. If the air conditioning is in energy-efficient mode, it determines the relationship between the battery SOC value (first charge level) and a second limit. When the first charge level is less than the second limit, it switches the current vehicle operating mode to power-efficient ECO mode.

[0067] In practical applications, when the first battery level is less than the second limit, HUT will pop up a window asking whether to switch to the power ECO mode. If yes, it will switch to the power ECO mode; otherwise, the vehicle will remain in the current power mode (first operating mode).

[0068] The energy-saving method for the power system provided in the embodiments of this application will be described in detail below. See also Figure 3 As shown, Figure 4 This is another schematic diagram illustrating the energy-saving process of the power system provided in this application embodiment. The specific process is as follows:

[0069] S401: Obtain the vehicle's first operating mode, the vehicle's air conditioning status, and the first battery level.

[0070] Obtain the current status of the vehicle.

[0071] S402: In response to the air conditioner being in the on state, the first operating mode being the power-saving mode, the air conditioner not being in the air conditioner energy-saving mode, and the first power consumption being less than the first limit, the air conditioner mode is adjusted to the air conditioner energy-saving mode.

[0072] The first limit is the threshold for whether to adjust the air conditioner to energy-saving mode. When the vehicle's current remaining battery power is less than the first limit, it means that the current battery power is insufficient, and the air conditioner needs to be adjusted to energy-saving mode in order to ensure the driving range.

[0073] In practical applications, the first and second limits can be adjusted according to the air conditioner's operating mode. For example, after determining whether the air conditioner is on, the current operating mode can be identified, such as heating or cooling. Different first and second limits can be set for different modes. For instance, when the air conditioner is in heating mode, the first limit can be set to 40% and the second limit to 30%. When the air conditioner is in cooling mode, the corresponding first limit is 30% and the second limit is 20%. In practical scenarios, the limit values ​​can be adaptively adjusted according to the air conditioner mode and actual conditions.

[0074] Specifically, the controller obtains the vehicle's current operating mode and whether the air conditioning is currently on. When the air conditioning is currently on, it determines whether the current operating mode (first operating mode) is a power-saving mode and whether the air conditioning is in an air conditioning energy-saving mode. When the air conditioning is not in an energy-saving mode, it determines the relationship between the current battery SOC value and the first limit. When the first charge is less than the first limit, it adjusts the current air conditioning to switch to an air conditioning energy-saving mode.

[0075] In practical applications, a user-selectable mode can be added. The HUT pop-up window asks whether to switch to the air conditioning ECO mode. If yes, then switch to the air conditioning ECO mode. If no, then no reminder will be given before the current battery charging gun is plugged in and the charging level is ≥70%.

[0076] The first limit can be set to 40%, which is higher than the SOC determined when the air conditioner is in ECO mode. This is because the air conditioner should not consume too much energy when ECO mode is not enabled. This prioritizes power and saves some energy for extended driving range.

[0077] The energy-saving method for the power system provided in the embodiments of this application will be described in detail below. See also Figure 5 As shown, Figure 5 This is another schematic diagram of the energy-saving method for a power system provided in an embodiment of this application.

[0078] The specific process is as follows:

[0079] S501: Obtain the vehicle's first operating mode, the vehicle's air conditioning status, and the first battery level.

[0080] Obtain the current status of the vehicle.

[0081] S502: In response to the air conditioner being in an on state, the first operating mode being a non-power energy-saving mode, the air conditioner being in a non-air conditioner energy-saving mode, and the first power consumption being less than a second limit, a first user instruction is obtained, the first user instruction being used to indicate whether to switch to the air conditioner energy-saving mode.

[0082] After the vehicle starts, the controller first checks if the air conditioning is on. If it is, the controller checks if the vehicle's power ECO mode is on. If not, the controller checks if the air conditioning ECO mode is on. If not, the controller checks if the current battery's remaining SOC (State of Charge) is greater than or equal to a second limit. If not, the controller obtains a first user instruction. This first user instruction indicates whether to switch to the air conditioning energy-saving mode. This state indicates that the vehicle's battery is low and it needs to enter energy-saving mode to improve the vehicle's range, preventing the vehicle from running out of power before reaching a charging station or ensuring there is still some battery power remaining before the next charge.

[0083] S503: In response to the first user instruction indicating that no mode switching should be performed, obtain the second battery level at the first moment.

[0084] The second charge level is the vehicle's charge level at the current moment.

[0085] In practical applications, based on the obtained command to switch to the air conditioning ECO mode, if the current instruction does not switch modes, the charging amount of the battery charging gun in this round (second charge) is obtained.

[0086] S504: In response to the second power level being less than the third limit, stop acquiring the first user instruction.

[0087] When the second charge level is not less than the third limit, that is, when the charge level is ≥70% (third limit) before the current battery charging, the reminder will no longer be issued to the vehicle user.

[0088] S505: Obtain the third battery level of the vehicle.

[0089] The third charge level refers to the remaining charge in the vehicle's battery at the second moment, since the first moment is earlier than the second moment.

[0090] S506: Determine the magnitude of the numerical relationship between the third energy level and the second limit.

[0091] In response to the third charge being less than the second limit, step S507 is executed;

[0092] In response to the third electrical charge being not less than the second limit, step S508 is executed.

[0093] S507: Adjust the first operating mode to the power-saving mode.

[0094] In practical application, HUT will pop up a window asking whether to switch to Power ECO mode. If yes, it will switch to Power ECO mode; otherwise, the vehicle will remain in the current power mode (first operating mode). This process ends here and no further processes will proceed.

[0095] S508: The vehicle remains in the first operating mode.

[0096] The vehicle will maintain its current power mode without any adjustments or changes.
