[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0044] In related technologies, the high-voltage loads in hybrid vehicles include the motor, a DC-DC converter (DC-to-DC converter) that converts high-voltage DC to low-voltage DC to power in-vehicle electrical equipment, and the air conditioning management system. Currently, hybrid vehicles are equipped with bidirectional chargers. These chargers can charge the battery when the charging gun is plugged in and discharge externally when the discharging gun is plugged in, converting the high-voltage DC power from the battery into approximately 220V AC power for use by external devices (i.e., the vehicle is in external discharge mode, V2L function is activated, and the battery charges other loads; this process is called third-party discharge). Currently, the management of external discharge in hybrid vehicles, when V2L function is activated, only ensures the hybrid vehicle continuously supplies power to external devices; there is no solution for when the power required by external devices is insufficient. Furthermore, it does not consider how to rationally allocate power to various electrical devices when the vehicle's high-voltage load, air conditioning system, and external devices are all using power simultaneously, to ensure that users can use various electrical devices at the same time.

[0045] To address the aforementioned problems, this application proposes a vehicle energy management method. In an embodiment of this application, the vehicle controller acquires the engine operating status, the current state of charge of the power battery, first operating data of the vehicle's high-voltage load, and second operating data of the external discharge gun. Based on the engine operating status, the current state of charge of the power battery, the first operating data, and the second operating data, the available power of the air conditioner is rationally allocated. While ensuring the normal use of the external load, the available power of the air conditioner is allocated to determine the allocated power. The vehicle controller sends the allocated power to the air conditioner controller, so that the air conditioner controller controls the power of the air conditioner during operation to not exceed the allocated power, thus balancing the power distribution among various electrical devices.

[0046] The embodiments of this application are described in detail below with reference to the accompanying drawings.

[0047] Reference Figure 1 A vehicle energy management method, applied to a vehicle controller, the method comprising:

[0048] Step S100: When the vehicle is in the external discharge condition, in response to the determination that the air conditioning is turned on, the engine operating status, the current state of charge of the power battery, the first operating data of the high voltage load of the vehicle, and the second operating data of the external discharge gun are obtained.

[0049] In this step, when the vehicle is in external discharge mode, it is parked and the discharge gun is plugged in to supply power to external loads (e.g., rice cookers, lights, etc.). After receiving the air conditioning start command, the vehicle controller acquires the engine operating status, the current state of charge (SOC) of the power battery, the first operating data of the vehicle's high-voltage loads (motors, DC-DC converters, etc.), and the second operating data of the external discharge gun. The external discharge gun can be connected to external loads, such as rice cookers, electric grills, etc. Since the air conditioning, high-voltage loads, and external discharge gun all require power from the vehicle, the above data is needed to determine the power allocation for the air conditioning to ensure a balanced power distribution among the various electrical devices.

[0050] Step S200: Determine the air conditioning power allocation based on the engine operating status, the current state of charge of the power battery, the first operating data, and the second operating data.

[0051] In this step, the vehicle controller allocates the available power of the air conditioner based on the generator operating status (e.g., engine started, engine not started), the current state of charge of the power battery, first operating data (e.g., the current output torque of the motor, the current speed of the motor, the output voltage of the DC-DC converter, the output current of the DC-DC converter, etc.) and second operating data (e.g., the current current of the discharge gun, the current voltage of the discharge gun, etc.), while ensuring the normal use of the external load, and determines the air conditioner power allocation.

[0052] Step S300: Send the allocated power of the air conditioner to the air conditioner controller so that the air conditioner controller controls the power of the air conditioner during operation to not exceed the allocated power of the air conditioner.

[0053] In this step, the vehicle controller sends the air conditioning power allocation to the air conditioning controller, which then controls the air conditioning operation based on the allocated power to ensure that the power consumption of the air conditioning during operation does not exceed the allocated power; thus balancing the power distribution among various electrical devices.

[0054] Specifically, through steps S100-S300, the vehicle controller allocates the available power of the air conditioner based on the engine operating status, the current state of charge of the power battery, the first operating data of the vehicle's high-voltage load, and the second operating data of the discharge gun. Under the condition of ensuring the normal use of the external load, the available power of the air conditioner is allocated and the allocated power of the air conditioner is determined. This solves the problem that when the vehicle is in the external discharge condition, the external load cannot be used normally after the user turns on the air conditioner.

[0055] In some embodiments, refer to Figure 2 In step S200, the engine operating state includes engine started and engine not started; the air conditioning power distribution includes a first power distribution and a second power distribution.

[0056] The step of determining the air conditioning power allocation based on the engine operating status, the current state of charge of the power battery, the first operating data, and the second operating data includes:

[0057] Step S210: In response to the engine operating state, start the engine and determine the first allocated power based on the preset target state of charge, the current state of charge, the first operating data, and the second operating data; or

[0058] Step S220: In response to the engine operating state being that the engine is not started, the first preset power is used as the second allocated power.

[0059] Specifically, when the engine is running (engine start), it indicates that the battery charge is low and the battery's discharge capacity is limited. Only after meeting the vehicle's high-voltage load and external load requirements is available power allocated to the air conditioner. The first allocated power for the air conditioner is determined based on the preset target state of charge, the current state of charge, the first operating data, and the second operating data.

[0060] When the engine is not running, it indicates that the power battery has a high charge and strong discharge capacity, which can meet the high voltage load of the vehicle and the use of external loads. Therefore, a higher power can be allocated to the air conditioner, and the first preset power can be used as the second power allocation for the air conditioner. The first preset power can be 5 kW for example.

[0061] In some embodiments, in step S210, determining the first allocated power based on a preset target state of charge, the current state of charge, the first operating data, and the second operating data includes:

[0062] In response to the current state of charge being higher than the target state of charge, the first allocated power is determined based on the first operating data and the second operating data.

[0063] Specifically, when the vehicle is in an external discharge condition, it is in a parked state. Compared to the vehicle in a normal driving condition, there is no need to rely on the power battery to ensure the vehicle's power performance. Therefore, when setting the target state of charge (SOC), the SOC value of the power battery can be appropriately reduced. For example, the target SOC under normal driving conditions is 50%, while the target SOC under external discharge conditions can be reduced to 30%. For example, if the current SOC is 50% and the target SOC is 45%, the current SOC is higher than the target SOC, indicating that the power battery has a good discharge capacity. In this case, the available power of the air conditioner is allocated based on the vehicle's high-voltage load and the actual output power of the discharge gun. The first allocated power of the air conditioner only needs to be determined based on the first operating data and the second operating data.

[0064] In some embodiments, in step S210, the method further includes:

[0065] In response to the current state of charge being lower than the target state of charge, the first allocated power is determined based on the first operating data, the second operating data, and the second preset power.

[0066] Specifically, for example, if the current state of charge (SOC) is 40% and the target SOC is 45%, the current SOC is lower than the target SOC, indicating that the power battery's discharge capacity is weak. Therefore, a lower power allocation needs to be made to the air conditioner to ensure the normal operation of other electrical equipment. Based on the vehicle's high-voltage load and the actual output power of the discharge gun, the available power for the air conditioner is allocated. The first allocated power for the available air conditioner power is determined based on the first operating data, the second operating data, and the second preset power.

[0067] When the engine is running and the current state of charge is lower than the target state of charge, it indicates that the power battery is discharging at a low level. Since the engine is running and charging the power battery at the same time, it is necessary to ensure that the power battery does not continue to lose power and to maintain the target state of charge as much as possible. At the same time, it is also necessary to supply power to the external load. In order to ensure the normal operation of the external load, it is necessary to further limit the upper limit of the available power of the air conditioner, that is, to set the maximum available power of the air conditioner to the second preset power.

[0068] In some embodiments, the high-voltage load includes a motor and a DC-DC converter; the first operating data includes: the current output torque of the motor, the current speed of the motor, the output voltage of the DC-DC converter, and the output current of the DC-DC converter; the second operating data includes the current current of the discharge gun and the current voltage of the discharge gun.

[0069] Determining the first allocated power based on the first operating data and the second operating data includes:

[0070] The current output power of the motor is calculated based on the current output torque and the current speed of the motor.

[0071] The current output power of the DC-DC converter is calculated based on its output voltage and output current.

[0072] The current output power of the discharge gun is calculated based on the current current and current voltage of the discharge gun.

[0073] The first allocated power is calculated based on the current output power of the motor, the current output power of the DC converter, the current output power of the discharge gun, and the reserved power.

[0074] Specifically, the vehicle controller acquires the current output torque of the motor, the current speed of the motor, the output voltage and current of the DC-DC converter, the current current of the discharge gun, and the current voltage of the discharge gun. Then, using the formula relating torque, speed, and power: Output power (P) = 2π × Speed ​​(n) × Torque (T), the current output power of the motor is calculated based on its current output torque and current speed.

[0075] Using the power calculation formula: Power (P) = Voltage (U) × Current (I), the current output power of the DC-DC converter can be calculated based on its output voltage and output current.

[0076] Using the power calculation formula: Power (P) = Voltage (U) × Current (I), the output power of the discharge gun is calculated based on the current current and voltage of the discharge gun.

[0077] The first allocated power is obtained by inputting the current output power of the motor, the current output power of the DC converter, the current output power of the discharge gun, and the reserved power into the air conditioner allocation power calculation formula (1).

[0078] Equation (1) is: Air conditioner power allocation = current output power of motor - current output power of DC converter - output power of discharge gun - reserved power.

[0079] The reserved power is to prevent the power battery from discharging beyond the specified discharge amount, which could damage the power battery. Therefore, the reserved power is set to ensure that the discharge amount of the power battery is within the specified range.

[0080] In some embodiments, the high-voltage load includes a motor and a converter; the first operating data includes: the current output torque of the motor, the current speed of the motor, the output voltage of the DC-DC converter, and the output current of the DC-DC converter; the second operating data includes the current current of the discharge gun and the current voltage of the discharge gun.

[0081] The step of determining the first allocated power based on the first operating data, the second operating data, and the second preset power includes:

[0082] The current output power of the motor is calculated based on the current output torque and the current speed of the motor.

[0083] The current output power of the DC-DC converter is calculated based on its output voltage and output current.

[0084] The current output power of the discharge gun is calculated based on the current current and current voltage of the discharge gun.

[0085] The actual available power is calculated based on the current output power of the motor, the current output power of the DC converter, the current output power of the discharge gun, and the reserved power.

[0086] The smaller of the actual available power and the second preset power is used as the first allocated power.

[0087] Specifically, the vehicle controller acquires the current output torque of the motor, the current speed of the motor, the output voltage and current of the DC-DC converter, the current current of the discharge gun, and the current voltage of the discharge gun. Then, using the formula relating torque, speed, and power: Output power (P) = 2π × Speed ​​(n) × Torque (T), the current output power of the motor is calculated based on its current output torque and current speed.

[0088] Using the power calculation formula: Power (P) = Voltage (U) × Current (I), the current output power of the DC-DC converter can be calculated based on its output voltage and output current.

[0089] Using the power calculation formula: Power (P) = Voltage (U) × Current (I), the output power of the discharge gun is calculated based on the current current and voltage of the discharge gun.

[0090] The first power allocation is obtained by inputting the current output power of the motor, the current output power of the DC converter, the current output power of the discharge gun, and the reserved power into the air conditioner power allocation calculation formula (2).

[0091] Equation (2) is: Air conditioner power allocation = min (current output power of motor - current output power of DC converter - output power of discharge gun - reserved power, second preset power).

[0092] The reserved power is to prevent the power battery from discharging beyond the specified discharge amount, which could damage the power battery. Therefore, the reserved power is set to ensure that the discharge amount of the power battery is within the specified range.

[0093] The second preset power is the highest power available for the air conditioner when the engine is running and the current state of charge is lower than the target state of charge. For example, the second preset power can be 2kW.

[0094] It should be noted that the embodiments of this application can also be further described in the following ways:

[0095] When the vehicle is in external discharge mode, the vehicle is stationary, and the discharge gun is inserted into the discharge port. The other end of the discharge gun is equipped with a socket, on which an electric barbecue grill (500W) and a light (160W) are plugged. The vehicle controller receives the air conditioning start command and acquires the engine operating status, the current state of charge of the power battery, the first operating data of the vehicle's high-voltage load, and the second operating data of the external discharge gun.

[0096] The current engine operating status is engine started. It is then determined whether the current state of charge (SOC) is lower than the target SOC. If the current SOC (for example, 50%) is higher than the target SOC (for example, 45%), the current output power of the motor is calculated based on its current output torque and current speed (for example, 7kW). The current output power of the DC-DC converter is calculated based on its output voltage and current (for example, 2kW). The output power of the discharge gun is calculated based on its current current and current voltage (for example, 660W). The air conditioning power allocation is calculated as follows: Current output power of the motor (7kW) - Current output power of the DC-DC converter (2kW) - Output power of the discharge gun (660W) - Reserved power (1kW); therefore, the available power of the air conditioner is 3.44kW.

[0097] If the current state of charge (SOC) (for example, 40%) is lower than the target SOC (for example, 45%), the current output power of the motor is calculated based on its current output torque and current speed (for example, 5kW). The current output power of the DC-DC converter is calculated based on its output voltage and current (for example, 2kW). The output power of the discharge gun is calculated based on its current current and current voltage (for example, 660W). The air conditioner's allocated power is calculated as: min(current output power of the motor (7kW) - current output power of the DC-DC converter (2kW) - output power of the discharge gun (660W) - reserved power (1kW), 2kW); therefore, the available power of the air conditioner is 2kW.

[0098] When the engine is not running, it means that the power battery has a high charge and strong discharge capacity, which can meet the high voltage load of the vehicle and the use of external loads. Therefore, the available power of the air conditioner is allocated to 5kw.

[0099] It should be noted that the method in this embodiment can be executed by a single device, such as a computer or server. The method can also be applied in a distributed scenario, where multiple devices cooperate to complete the task. In such a distributed scenario, one of these devices may execute only one or more steps of the method in this embodiment, and the multiple devices will interact with each other to complete the method described.
