[0001] Cross-reference

[0002] This disclosure claims priority to Chinese Patent Application No. 202410675231.6, filed on May 28, 2024, entitled "A method and system for controlling vehicle power consumption, and a vehicle", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of vehicle thermal runaway treatment technology, specifically to a vehicle power consumption control method and system, and a vehicle. Background Technology

[0004] In pure electric vehicles, the power battery pack is a high-voltage, high-density energy storage component. Thermal runaway can lead to spontaneous combustion and explosion of the battery pack within a short period. Therefore, when the cell temperature of the high-voltage battery reaches the set thermal runaway risk threshold, the battery cooling system will activate. At this time, the high-voltage battery cannot supply power, and the low-voltage battery must support the cooling system and the vehicle's basic power consumption. During this process, it is necessary to consider whether the vehicle's low-voltage battery can meet the power consumption requirements of the cooling system. If it cannot, the cooling system will not be able to operate continuously for an extended period, preventing the cell temperature from dropping to a safe threshold and potentially causing the battery pack to spontaneously combust and explode. Summary of the Invention

[0005] The purpose of this disclosure is to propose a vehicle power consumption control method and system, and a computer-readable storage medium, so as to avoid the vehicle's low-voltage battery failing to meet the power consumption requirements of the battery cooling system after thermal runaway.

[0006] To achieve the above objectives, embodiments of this disclosure provide a method for controlling vehicle energy consumption, the method comprising:

[0007] When a high-voltage battery thermal runaway fault occurs, the power supply to the high-voltage battery is cut off;

[0008] Turn on the battery cooling function;

[0009] Initiate an arbitration to cut off power; if the arbitration is successful, cut off the vehicle's power.

[0010] When the vehicle speed is less than or equal to the preset speed threshold, the vehicle gear will be switched to park.

[0011] When the vehicle power is cut off, the vehicle speed is less than or equal to the preset speed threshold, and the vehicle gear is in park, the vehicle mode will be switched to standby mode, and the vehicle mode switching function will be disabled.

[0012] Embodiments of this disclosure also provide a vehicle energy consumption control system, characterized in that it includes:

[0013] The high-voltage battery management system is set to monitor whether the high-voltage battery has experienced a thermal runaway fault. If so, it will cut off the power supply to the high-voltage battery and send a thermal runaway alarm signal to the battery cooling system, power control system and usage mode management system.

[0014] The battery cooling system is configured to activate the battery cooling function in response to the thermal runaway alarm signal.

[0015] The power control system is configured to respond to the thermal runaway alarm signal, perform a power cut-off arbitration, and if the arbitration is successful, cut off the vehicle power and send a shift request to the gear control system to request the vehicle gear to be switched to parking gear.

[0016] The gear control system is configured to respond to the gear shift request by shifting the vehicle gear to parking when the vehicle speed is less than or equal to a preset speed threshold.

[0017] The mode management system is configured to respond to the thermal runaway alarm signal by switching the vehicle mode to standby mode and disabling the vehicle mode switching function when the vehicle power is cut off, the vehicle speed is less than or equal to a preset speed threshold, and the vehicle gear is in park.

[0018] Embodiments of this disclosure also provide a vehicle including the above-described vehicle power consumption control system.

[0019] This disclosure provides a vehicle power consumption control method and system, as well as a vehicle, which can effectively control vehicle power consumption when the high-voltage battery of a vehicle experiences thermal runaway. This is achieved by cutting off vehicle power, switching the vehicle gear to parking, switching the vehicle mode to standby mode, and disabling the vehicle mode switching function. This ensures that the low-voltage battery has sufficient power to support the operation of the battery cooling system, thereby preventing the thermal runaway fault from worsening and ensuring the safety of the vehicle and passengers.

[0025] The detailed description of the accompanying drawings is intended to illustrate some present embodiments of this disclosure and is not intended to represent only the forms in which this disclosure can be implemented. It should be understood that the same or equivalent functionality may be performed by different embodiments intended to be included within the scope of this disclosure.

[0026] One embodiment of this disclosure provides a method for controlling vehicle energy consumption. Referring to Figure 1, the method includes the following steps:

[0027] Step S10: When a high-voltage battery thermal runaway fault occurs, the power supply to the high-voltage battery is cut off.

[0028] Specifically, battery cells are the basic building blocks of high-voltage batteries. They are combined in series or parallel to form a high-voltage battery to provide sufficient voltage and capacity for electric vehicles. Each battery cell generates heat during charging and discharging. Moreover, due to factors such as chemical reactions of internal battery materials and resistance loss, the temperature of the battery cell will change with use. During vehicle operation, the temperature of the high-voltage battery cells is monitored. When the cell temperature reaches the set thermal runaway risk threshold, a high-voltage battery thermal runaway fault is determined to have occurred.

[0029] Step S20: Activate the battery cooling function.

[0030] Specifically, electric vehicles are equipped with a battery cooling system designed to manage the temperature of the high-voltage battery. Since batteries generate heat during charging and discharging, especially under high load or rapid charging, a battery cooling system is needed to control the temperature of the high-voltage battery, keeping it within its optimal operating range, preventing overheating and thermal runaway, and extending its lifespan. In this embodiment, when a high-voltage battery thermal runaway fault occurs, the battery cooling function of the battery cooling system is activated to cool the high-voltage battery.

[0031] Step S30: Perform a power cut-off arbitration. If the arbitration is successful, the vehicle power is cut off.

[0032] Specifically, power cut-off arbitration, which involves cutting off vehicle power if the arbitration is successful, is a safety protection measure for electric vehicles in the event of thermal runaway of the high-voltage battery. Power cut-off arbitration is a decision-making process aimed at determining whether the vehicle's power output should be cut off to prevent further deterioration of the thermal runaway fault. The decision-making process considers multiple factors, including but not limited to vehicle speed, vehicle position, vehicle status, and driver instructions. Specifically, if the vehicle is traveling at high speed, suddenly cutting off power may lead to loss of control or a rear-end collision. Vehicle position refers to whether the vehicle is in a safe location, such as on a highway, and whether there is sufficient space to park safely. Vehicle status refers to whether the vehicle is stable and whether there are other potential safety risks. Driver instructions refer to whether an emergency stop instruction has been received from the driver. If the assessment based on these factors indicates that cutting off power is safe, i.e., it will not lead to more serious risks or accidents, then the arbitration is successful. Once the arbitration is successful, the vehicle's power system will be cut off, which means that the electric motor will stop receiving power from the high-voltage battery, the vehicle will lose power, and begin to decelerate until it stops.

[0033] It should be understood that the purpose of step S30 is to find a balance between ensuring passenger safety and reducing the risk of thermal runaway. If cutting off power could lead to a more dangerous situation, such as a sudden stop on a busy road, the system may choose not to immediately cut off power, but instead allow the driver to move the vehicle to a safer location before cutting off power. Conversely, if it is determined that cutting off power is safe, the system will perform the cut-off operation to prevent further development of thermal runaway.

[0034] Step S40: When the vehicle speed is less than or equal to a preset speed threshold, switch the vehicle gear to parking gear.

[0035] Specifically, step S40 refers to an operation taken to ensure the vehicle can stop safely after a thermal runaway fault occurs in the electric vehicle's high-voltage battery. The preset speed threshold here is a safe speed limit set in the vehicle system to determine when it is safe to shift to parking (P) gear, typically set to 5 km / h. After power is cut off, the vehicle will gradually decelerate and eventually stop. In some cases, if the vehicle speed is very high, it may take a long time to come to a complete stop. Furthermore, if the driver applies emergency braking, the vehicle may decelerate even faster. When the vehicle speed drops to or below 5 km / h, the vehicle's gear is shifted from a driving gear (such as D or R) to P gear. P gear locks the wheels, preventing the vehicle from moving and ensuring it stops in a safe position.

[0036] It should be understood that step S40, which determines the power system status, vehicle speed, and gear, is to ensure that the mode switching action is performed only when the vehicle is absolutely stationary, thus ensuring functional safety.

[0037] Step S50: When the vehicle power is cut off, the vehicle speed is less than or equal to the preset speed threshold and the vehicle gear is in park, the vehicle mode is switched to standby mode and the vehicle mode switching function is disabled.

[0038] Specifically, "vehicle power cut off" indicates that the vehicle's power system is in a non-ready state (stopped working) to prevent further deterioration of battery thermal runaway; "vehicle speed less than or equal to a preset speed threshold" indicates that the vehicle has essentially stopped; "vehicle gear in P" indicates that the wheels are locked and the vehicle will not move unexpectedly; when the vehicle has not experienced battery thermal runaway, the vehicle mode is Comfort mode. When all the conditions of "vehicle power cut off," "vehicle speed less than or equal to a preset speed threshold," and "vehicle gear in Park" are met simultaneously, the vehicle mode is switched to Standby mode. This is to minimize vehicle energy consumption. Compared to Comfort mode, Standby mode only maintains the operation of necessary systems, such as the battery cooling system and other critical safety functions. In Standby mode, the functions and performance of Comfort mode are disabled, thereby limiting unnecessary power consumption and saving overall vehicle energy consumption. Disabling the vehicle mode switching function is to prevent the driver or vehicle system from mistakenly switching the vehicle mode in an emergency, which could lead to increased battery energy consumption or divert critical power resources used for the cooling system.

[0039] These measures ensure that the vehicle remains in the safest possible condition while ensuring that the low-voltage battery has sufficient charge to support critical safety functions, such as the battery cooling system, thereby preventing the escalation of thermal runaway failures and ensuring the safety of the vehicle and its passengers.

[0040] In some embodiments, the method further includes:

[0041] Step S60: When the vehicle mode is switched to standby mode, start the timer, cut off the power supply of unnecessary loads in standby mode, and disable the load power-on request function; when the timer duration is equal to the preset duration, cut off the power supply of necessary loads in standby mode.

[0042] Specifically, step S60 is an additional step implemented after the vehicle mode has been switched to standby mode in order to further manage power consumption and ensure battery safety. When the vehicle mode is switched to standby mode, a timer will start, and the power supply of non-essential loads in standby mode will be cut off. The non-essential loads refer to the power supply of electrical system components and equipment that do not affect the basic functions of the vehicle, such as the power supply of interior lighting, electric seat adjustment, electric folding rearview mirrors, electric windows and sunroof, etc. Standby power and constant load power, such as the battery cooling system and the warning system (instrument, voice playback device), will be maintained in standby mode to ensure that the battery cooling system can work normally to cool the battery. The warning system is set to alarm the occupants of the vehicle to indicate that the vehicle has experienced battery thermal runaway and that they need to leave the vehicle as soon as possible.

[0043] At the same time, the power-on request function of these unnecessary loads will be blocked to prevent them from automatically restarting after the power is cut off or being started by the driver by mistake, thereby ensuring that power resources are used for the most critical functions.

[0044] When the preset timer duration is reached, the standby power supply and constant power supply to the loads in standby mode will be cut off. It should be noted that the preset timer is designed to provide users with sufficient time to safely exit the vehicle. In the event of battery thermal runaway, passengers and the driver have enough time to recognize the danger and take action to protect their safety. This timer is designed based on an estimate of the rate of thermal runaway development, ensuring that users have enough time to leave the vehicle and avoid potential fire or explosion risks. This timer may be 5-10 minutes, for example, 6 minutes. When the timer expires, the standby power supply and constant power supply to the loads will be cut off to further reduce power consumption. Standby power refers to electronic systems or equipment that need to remain powered even after the engine is turned off. Constant power supply refers to electrical loads that remain powered regardless of whether the vehicle is running or not.

[0045] Therefore, the purpose of step S60 is to take a series of measures through the intelligent power distribution system to ensure the safety of the vehicle and passengers in the event of a high-voltage battery thermal runaway failure, while minimizing power consumption and extending the support time of the low-voltage battery. By cutting off the power to non-essential loads and starting a 6-minute timer, sufficient time can be ensured for the driver and passengers to become aware of the warning and take action to protect their safety.

[0046] In some embodiments, step S60 includes:

[0047] When the timeout period equals the preset period, the status information of the occupants inside the vehicle is obtained. Based on the status information, it is determined whether there are any occupants inside the vehicle. If not, the standby power supply and the constant power supply are cut off. If so, the cutoff of the standby power supply and the constant power supply is temporarily suspended. The standby power supply and the constant power supply are cut off again when there are no occupants inside the vehicle.

[0048] Specifically, the system uses seat sensors and in-vehicle cameras to obtain occupant status information. The vehicle is equipped with these sensors to detect the presence of occupants. The seat sensors detect weight (i.e., someone is sitting) on ​​the seats, while the cameras provide visual recognition to confirm occupant presence. By analyzing the occupant status information provided by the sensors and cameras, the system determines whether there are occupants inside. If no occupants are detected, the system will cut off standby power and constant power to conserve battery power, avoiding unnecessary energy consumption. If the system detects occupants, it will temporarily delay cutting off standby power and constant power, keeping certain vehicle systems in standby mode to alert the occupants and prompt them to open the doors and leave. Once the occupants have left the vehicle and the system detects no one inside again, it will cut off all non-essential power to protect the vehicle's battery.

[0049] In some embodiments, the method further includes:

[0050] Step S70: During the timing process, a thermal runaway alarm is triggered.

[0051] Specifically, step S70 refers to the vehicle control system continuously issuing thermal runaway warnings when a thermal runaway fault occurs in the high-voltage battery of an electric vehicle, in order to ensure that the driver and passengers are aware of the potential danger in a timely manner and take appropriate measures. These warnings include, but are not limited to, warning lights on the instrument panel, audible alerts, and text prompts. The warning lights on the instrument panel will illuminate to alert the driver of the potential risk of thermal runaway. The audible alerts will sound an alarm to attract the attention of the driver and passengers. The text prompts will display warning information related to thermal runaway on the information display screen if the vehicle is equipped with one. Upon receiving these warnings, the driver and passengers should immediately follow the emergency operating guidelines and evacuate the vehicle at a safe distance.

[0052] In some embodiments, the method further includes:

[0053] Step S80: When the high-voltage battery thermal runaway fault is eliminated, the vehicle mode switching function and the load power-on request function are unlocked.

[0054] Specifically, step S80 describes how to restore the vehicle to normal operating status after the high-voltage battery thermal runaway fault is resolved, and how to allow rescue personnel to perform further diagnosis and operation on the vehicle. Rescue personnel can use the diagnostic commands of the diagnostic tool to unlock the vehicle mode switching function, allowing the driver or rescue personnel to switch vehicle modes as needed. At the same time, the load power-on request function is also unlocked, allowing the driver or rescue personnel to restart unnecessary loads on the vehicle as needed, and the vehicle returns to normal operating status.

[0055] Figure 2 shows a flowchart of a specific embodiment of the method disclosed herein. In the embodiment of Figure 2, the timing duration is 6 minutes, and the changes in the vehicle current under the high-voltage battery thermal runaway fault are shown in Table 1 below:

[0056] Table 1

[0057] Based on the content of Table 1 above, it can be seen that after the vehicle power consumption control method of this embodiment is introduced, the vehicle current is reduced by 48%, and the corresponding battery cooling system working time can be increased by 48%.

[0058] It should be noted that the steps of the above-described embodiments can be executed by one or more controllers / actuators, such as the vehicle power consumption control system shown in Figure 3, which includes a high-voltage battery management system 1, a battery cooling system 2, a power control system 3, a gear control system 4, a usage mode management system 5, an intelligent power distribution system 6, and a prompting system 7, etc.

[0059] Corresponding to the method of the above embodiments, another embodiment of this disclosure provides a vehicle energy consumption control system. Referring to Figures 3-4, the system of this embodiment includes:

[0060] The high-voltage battery management system 1 is set to monitor the cell temperature of the high-voltage battery, and determine whether a thermal runaway fault has occurred based on the cell temperature. If so, it will conduct high-voltage power arbitration. If the arbitration is successful, it will cut off the power supply to the high-voltage battery and send a thermal runaway alarm signal to the battery cooling system 2, the power control system 3, and the usage mode management system 5.

[0061] Battery cooling system 2 is configured to activate the battery cooling function in response to the thermal runaway alarm signal, thereby cooling the high-voltage battery.

At the same time, a vehicle mode signal (at this time the vehicle mode is standby mode) is sent to the intelligent power distribution system 6.

[0067] In some embodiments, the system of this embodiment further includes a prompting system 7, to which the high-voltage battery management system 1 sends a thermal runaway alarm signal; the prompting system 7 responds to the thermal runaway alarm signal to provide a thermal runaway alarm prompt until the timer ends, at which point the thermal runaway alarm prompt stops, and the intelligent power distribution system 6 cuts off the power supply to the prompting system 7 to further save power consumption.
