[0048] Exemplary Methods

[0049] See also Figure 1 In an exemplary embodiment, a method for controlling a vehicle discharge system is provided, comprising:

[0050] Step 101: Obtain operating parameters of a vehicle load and battery status information of a vehicle battery.

[0051] In some embodiments, a vehicle load is a device on a vehicle that requires electricity, and operating parameters include but are not limited to the load power fluctuation rate, voltage fluctuation rate, and current change rate of the vehicle load. The load power fluctuation rate can be determined by obtaining the change in voltage per unit time, the voltage fluctuation rate can be determined by obtaining the change in load power per unit time, and the current change rate can be determined by obtaining the change in current per unit time. Battery status information includes but is not limited to the remaining battery capacity (SOC).

[0052] The above-mentioned change in load power is the difference between the power at the current moment and the previous moment, the change in voltage is the difference between the voltage at the current moment and the previous moment, and the change in current is the difference between the current at the current moment and the previous moment.

[0053] Step 102: Determine load status information of the vehicle load according to the operating parameters.

[0054] In some embodiments, the load status information indicates changes in the vehicle load, including a load surge state, a load drop state, and a load stable state. In an optional embodiment, the operating parameters include load power fluctuation rate, voltage fluctuation rate, and current change rate, and determining the load status information based on the operating parameters includes:

[0055] When the load power fluctuation rate is greater than a first preset fluctuation rate threshold, or the current change rate is greater than a first dynamic threshold, determining that the load state information is a load surge state;

[0056] When the load power fluctuation rate is less than a second preset fluctuation rate threshold, or the current change rate is less than a second dynamic threshold, determining that the load state information is a load dump state; the second preset fluctuation rate threshold is less than the first preset fluctuation rate threshold, and the second dynamic threshold is less than the first dynamic threshold;

[0057] When the load power fluctuation rate is greater than or equal to a second preset fluctuation rate threshold, and the voltage fluctuation rate is within a preset range, the load state information is determined to be a load stable state.

[0058] In some embodiments, if the load power fluctuation rate exceeds a first preset fluctuation rate threshold (for example, the power increase in a short period of time exceeds 10% of the current power, for example, the first preset fluctuation rate threshold can be set to +10%), or the current change rate exceeds a first dynamic threshold (for example, the first dynamic threshold can be +10%), it is determined to be a load surge scenario.

[0059] If the load power fluctuation rate is less than the second preset fluctuation rate threshold (for example, the power drop in a short period of time exceeds 10% of the current power, for example, the first preset fluctuation rate threshold can be set to -10%), or the current change rate is lower than the second dynamic threshold (for example, the first dynamic threshold can be -10%), it is determined to be a load dump scenario.

[0060] If the load power fluctuation rate is greater than or equal to the second preset fluctuation rate threshold, and the voltage fluctuation rate is within a safe range, it is determined to be a load stable scenario.

[0061] Step 103: Determine a discharge start / stop delay strategy based on the battery status information and the load status information. The discharge start / stop delay strategy is used to instruct a delay control mechanism for starting or stopping a discharge process when the vehicle discharge system performs a discharge operation.

[0062] In some embodiments, the discharge start and stop delay is adaptively adjusted by real-time analysis of load power fluctuation characteristics (such as load power fluctuation rate, voltage fluctuation rate, and current change rate) and battery status information (such as SOC and temperature).

[0063] Among them, related technologies use a fixed delay strategy control method. When the load suddenly increases, the fixed delay may cause the battery to over-discharge due to continuous high power output, shortening the battery life. When the load is stable or suddenly drops, the fixed delay may cause energy waste due to delayed adjustment, reducing discharge efficiency. In this embodiment, the load status information includes load sudden increase status and load sudden decrease status. In the load sudden increase status, the delay is shortened to prioritize response to demand and can also simultaneously limit the discharge rate to avoid battery over-discharge. In the load stable / sudden drop status, the delay is extended to reduce unnecessary start-stop losses and optimize battery cycle efficiency.

[0064] In an optional embodiment, the load state information includes a load sudden increase state, a load sudden decrease state, and a load stable state. Determining a discharge start / stop delay strategy based on the battery state information and the load state information includes:

[0065] Determining an extension amount of the discharge start / stop delay time based on the battery status information;

[0066] When the load state information indicates a sudden load increase, shortening the discharge start / stop delay time according to the extension amount;

[0067] When the load state information is a load dump state or a load stable state, the discharge start and stop delay time is extended according to the extension amount.

[0068] In some embodiments, the battery status information includes the battery temperature, and the battery stability is positively correlated with the extension of the delay time, that is, the higher the battery stability, the longer the delay, and the lower the discharge rate.

[0069] In the case of a sudden increase in load, the discharge start and stop delay is shortened to quickly respond to load demand and simultaneously limit the maximum discharge current to avoid over-discharge of the battery. In the case of a stable load or a sudden drop in load, the discharge start and stop delay is extended to reduce energy loss from frequent starts and stops.

[0070] Furthermore, if the battery temperature exceeds a safety threshold (e.g., 50°C), even if the vehicle is under stable load, the delay is extended and power output is reduced to improve discharge safety. If the voltage fluctuation rate exceeds a threshold (e.g., the voltage fluctuation amplitude exceeds ±10%), the delay is shortened and power is limited to prevent overcurrent risks.

[0071] After obtaining the above-mentioned discharge start-stop delay strategy, the discharge start-stop delay duration of the vehicle discharge system can be shortened or extended according to the discharge start-stop delay strategy.

[0072] In some embodiments, by shortening or extending the discharge start and stop delay duration of the vehicle discharge system according to the discharge start and stop delay strategy, a discharge start and stop delay strategy that matches the vehicle's load status information and battery status information can be dynamically determined, and load power fluctuations can be responded to in real time, thereby avoiding the risk of over-discharge and energy waste, improving discharge efficiency, and reducing battery loss.

[0073] After determining the discharge start / stop delay strategy, the vehicle's discharge system circuit is closed according to the calculated delay time, initiating discharge. During discharge, the system continuously monitors battery status information (such as SOC and temperature). If the SOC falls below a preset safety threshold (e.g., 20%), discharge is immediately terminated and protection is triggered. If the temperature exceeds a dynamic threshold (e.g., a rapid temperature rise), the system dynamically increases the delay and reduces power.

[0074] During the discharge process, the vehicle load's operating parameters and battery status information can also be verified in real time. If a sudden increase in load causes the voltage fluctuation rate to exceed the standard, the delay will be adjusted immediately and the current will be limited. If the battery temperature continues to rise, it will be forced to enter a degraded discharge mode (extending the delay and reducing the power).

[0075] In an optional embodiment, the control method of the vehicle discharge system of the present application further includes:

[0076] In the case where an interruption of the vehicle discharge system is detected, determining a target interruption type according to the operating parameters and the battery status information;

[0077] Determining a target recovery strategy corresponding to the target interruption type;

[0078] When the vehicle discharge system meets a recovery condition, discharging is restored according to the target recovery strategy, where the recovery condition represents a condition that enables the vehicle discharge system to discharge normally.

[0079] In related technologies, when faced with a system interruption, the recovery mechanism relies on a single condition (such as a scheduled restart or manual intervention) and is unable to distinguish the type of fault (such as a momentary short circuit or continuous over-discharge). After the fault is eliminated, secondary damage may occur due to failure to verify environmental parameters (such as temperature failure to recover).

[0080] In this embodiment, the target interruption type can be determined based on the operating parameters and the battery status information, and then a recovery strategy corresponding to the interruption type is selected, thereby improving the recovery effect of the vehicle discharge system.

[0081] In an optional embodiment, the operating parameters include circuit parameters, the circuit parameters include voltage and / or current, and the battery status information includes the remaining power of the vehicle battery;

[0082] Determining a target interruption type according to the operating parameters and the battery status information includes:

[0083] Within a first preset time period, a change in the circuit parameter is greater than a preset parameter change, and the circuit parameter recovers within a second preset time period, determining that the target interruption type is a transient fault, and the first preset time period is less than the second preset time period;

[0084] At least one of the following first and second conditions is met to determine that the target interruption type is a continuous fault, wherein the first condition includes that the change in the circuit parameter is greater than the preset circuit parameter change, and the circuit parameter has not recovered within a second preset time period, and the second condition includes that the remaining power has not returned to the preset power threshold.

[0085] In some embodiments, when determining a transient fault, it is possible to detect whether the voltage / current undergoes a sudden change (e.g., after a short circuit, both the voltage and current drop to 0), but returns to stability within a second preset time period (e.g., 5 seconds), indicating that the fault only occurred for a short period of time. The load operating parameters and battery status information at the time of the fault can be recorded and marked as a transient fault. When determining a persistent fault, the duration of the fault can be detected. If it exceeds the second preset time period (e.g., 5 seconds) and has not recovered, or the SOC has not returned to a safe threshold, it will be marked as a persistent fault (e.g., battery over-discharge, persistently high temperature).

[0086] In an optional embodiment, the target interruption type includes a transient fault and a persistent fault, and determining a target recovery strategy corresponding to the target interruption type includes:

[0087] When the target interruption type is a transient fault, determining the target recovery strategy includes: configuring a delayed discharge parameter to be an initial delay parameter, a discharge power to be a first preset percentage of a preset discharge power, and adjusting the discharge power to be a preset discharge power after verifying the battery status information a first preset number of times;

[0088] When the target interruption type is a continuous fault, determining the target recovery strategy includes: configuring the delayed discharge parameter to be a preset multiple of the initial delay parameter, the discharge power to be a second preset percentage of the preset discharge power, and, after the battery status information is verified for a second preset number of times, adjusting the discharge power to the preset discharge power.

[0089] In some embodiments, after determining the target interruption type, the vehicle discharge system may configure corresponding recovery conditions according to the interruption type, and resume discharging after the recovery conditions are met.

[0090] Among them, primary recovery conditions can be configured for transient faults, including: the load voltage returns to a normal range (such as within ±5% of the nominal voltage) and the battery temperature drops below a safety threshold (such as 45°C).

[0091] For persistent faults, degradation recovery conditions can be configured, including: SOC returns to the recovery threshold (such as 25%); the temperature drop rate meets the drop requirement (such as 2°C per minute).

[0092] Then, after the recovery conditions are met, the corresponding recovery process is initiated. For transient faults, the primary recovery process is initiated, including: restarting discharge according to the initial delay parameters; initially limiting the discharge power to 80% of the normal value and continuously monitoring stability; if three consecutive checks pass (SOC is stable and the temperature is normal), gradually restoring to normal power. For persistent faults, the degraded recovery process is initiated, including: extending the discharge start and stop delay to 1.5 times the initial value; limiting the discharge power to 50% of the normal value and gradually increasing the power (10% each time, with an interval of 30 seconds); if five consecutive checks pass, the degraded mode is released and the initial parameters are restored.

[0093] In an optional embodiment, after obtaining the operating parameters of the vehicle load and the battery status information of the vehicle battery, the method further includes:

[0094] determining whether the operating parameter and / or the battery status information satisfies a circuit protection condition; the circuit protection condition indicating that the vehicle battery is in a high-risk state;

[0095] If the circuit protection conditions are met, the circuit of the vehicle discharge system is disconnected and an alarm is issued;

[0096] After the vehicle discharge system resumes discharging, a safety check is performed on the operating parameters and / or the battery status information.

[0097] In some embodiments, the circuit protection conditions include at least one of the following: SOC less than a power safety threshold (e.g., 20%), battery temperature greater than a temperature safety threshold (e.g., 50°C), voltage fluctuation greater than a dynamic threshold (e.g., ±15%), or current change greater than a limit threshold (20A / ms). If the operating parameters and battery status information meet at least one of the above conditions, the vehicle discharge system circuit is disconnected and an audible and visual alarm is triggered to notify the user of the fault and detect it in a timely manner.

[0098] After the user eliminates the fault, if the vehicle discharge system resumes discharging, it must meet the safety conditions of all parameters during the recovery phase before resuming discharge to improve system discharge safety. Safety conditions are used to indicate the conditions that enable the vehicle discharge system to operate safely.

[0099] Among them, safety conditions include: SOC is greater than or equal to the recovery threshold (such as 25%); battery temperature is less than or equal to the temperature safety threshold (such as 45°C); voltage fluctuation rate is less than the voltage fluctuation safety threshold (such as ±10%).

[0100] Furthermore, the control method of the vehicle discharge system of the present application can also obtain historical discharge data, and based on the historical discharge data and real-time load operating parameters, predict the future SOC and temperature change path (such as predicting the parameter trend in the next 5 minutes through a sliding window algorithm). If the prediction result is close to the risk threshold, the degraded discharge or alarm is triggered in advance to avoid passive protection lag.

[0101] Through cross-checking and predictive control of multi-dimensional parameters (operating parameters of the vehicle load and battery status information of the vehicle battery), safety in extreme scenarios (such as high temperature and highly fluctuating loads) can be significantly improved.

[0102] The control method of the vehicle discharge system of the present application can realize dynamic delay adjustment, and adaptively adjust the discharge start and stop delay by real-time analysis of the fluctuation characteristics of the load power (such as fluctuation rate, trend change rate) and battery status (such as SOC, temperature). When the load suddenly increases, the delay is shortened to respond to the demand first, but the discharge rate is simultaneously limited to avoid over-discharge of the battery. The delay is dynamically shortened to ensure power supply. However, if a short-circuit fault occurs subsequently, the hierarchical recovery mechanism can quickly isolate the fault and restart to avoid long-term stagnation of the system. When the load is stable / suddenly dropped, the delay is extended to reduce unnecessary start-stop losses and optimize battery cycle efficiency.

[0103] Through multi-parameter linkage verification, dynamic parameters such as temperature and voltage fluctuation are introduced into the delay calculation (for example, extending the delay at high temperatures to reduce discharge intensity), avoiding misjudgments caused by relying solely on SOC and ensuring the conservatism of the discharge strategy. By dynamically adapting to the load and battery status, discharge efficiency and battery life are balanced, avoiding the conflict between efficiency and safety in traditional solutions.

[0104] Different hierarchical recovery strategies are adopted for different fault types. For instantaneous faults (such as automatic elimination of short circuits), discharge is immediately restarted by quickly detecting the fault elimination conditions (such as voltage restoration and stability). For persistent faults (such as SOC not recovered or temperature is too high), the battery is forced to enter low-power mode and the delay is extended, gradually transitioning to normal discharge to avoid hardware damage caused by forced restart.

[0105] During the recovery phase, parameters such as SOC, temperature, and voltage fluctuation must be verified simultaneously to verify multi-parameter safety conditions. This prevents restarts with potential hazards and ensures that both the environment and battery status meet safety requirements. This avoids the risk of secondary failures caused by a single condition triggering recovery in traditional solutions, improving the system's fault tolerance in complex scenarios.

[0106] Configure multi-dimensional safety verification methods and set complex protection conditions (such as "SOC is too low, temperature is too high, or voltage fluctuates violently"). Triggering any of these conditions triggers protection mode; all parameter safety conditions must be met simultaneously during the recovery phase. Active risk prediction can be performed, combining real-time load trends with historical data to predict future parameter change paths (such as a continued downward trend in SOC), triggering degraded discharge or alarms in advance to avoid delayed passive protection. In extreme scenarios (such as continuous discharge in high-temperature environments), it proactively avoids safety hazards such as overheating and overcurrent, improving system robustness.

[0107] Through the synergistic effect of dynamic adjustment, hierarchical recovery and active pre-control, the system is significantly superior to traditional solutions in discharge efficiency, abnormal fault tolerance and safety protection, and can achieve better adaptability and reliability without relying on specific data.

[0114] The functions implemented by each unit in the above vehicle discharge system control device can be implemented by the same or different processors, which is not limited in the embodiment of the present application.

[0115] It should be understood that each unit in the above device can be implemented in the form of a processor calling software. For example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions. The processor calls the instructions stored in the memory to implement any of the above methods or realize the functions of each unit of the device. The processor can be a general-purpose processor, such as a CPU or a microprocessor, and the memory can be a memory within the device or a memory outside the device. Alternatively, the units in the device can be implemented in the form of hardware circuits. The functions of some or all units can be realized by designing the hardware circuits. The hardware circuit can be understood as one or more processors. For example, in one implementation, the hardware circuit is an ASIC, and the functions of some or all of the above units can be realized by designing the logical relationships between the components within the circuit. For another example, the hardware circuit can be implemented by a PLD. For example, an FPGA can include a large number of logic gate circuits.

All units of the above device can be implemented entirely in the form of a processor calling software, or entirely in the form of hardware circuits, or partially in the form of a processor calling software, with the remaining parts implemented in the form of hardware circuits.

[0116] In an embodiment of the present application, a processor is a circuit with the ability to process signals. In one implementation, the processor may be a circuit with the ability to read and execute instructions, such as a CPU, a microprocessor, a GPU, or a DSP. In another implementation, the processor may implement certain functions through the logical relationship of a hardware circuit, and the logical relationship of the hardware circuit may be fixed or reconfigurable, such as a hardware circuit implemented by an ASIC or PLD, such as an FPGA.

The at least one processor may be of different types, such as a CPU and an FPGA, a CPU and an artificial intelligence processor, a CPU and a GPU, etc.

[0119] Exemplary electronic devices

[0120] Another embodiment of the present application also proposes a vehicle discharge system, including: a load monitoring module, an adaptive delay control module, a battery status monitoring module, a safety protection module and a power switching module. The modules are connected through a communication bus to achieve data interaction between modules and synchronize vehicle status information (such as whether the vehicle is in driving mode).

[0121] The load monitoring module collects real-time data on external load parameters such as power, voltage, and current, and analyzes the load's operating parameters (such as power fluctuation rate, voltage fluctuation rate, and current variation trends) based on these parameters. The module then determines the vehicle's load status (e.g., "load surge" or "load stability") based on these operating parameters and transmits this information to the adaptive delay control module.

[0122] The adaptive delay control module dynamically calculates discharge start and stop delay parameters based on load and battery status, and outputs control instructions to the power switching module. During sudden load increases, the delay is shortened to prioritize power supply while simultaneously limiting the discharge rate. During stable loads, the delay is extended to reduce start-stop losses. The delay strategy is adjusted based on dynamic parameters such as battery temperature and voltage fluctuation.

[0123] The battery status monitoring module monitors the battery's SOC, temperature, voltage fluctuation rate, and state of health (SOH) in real time and outputs safety status signals. Battery safety status signals (such as "SOC is too low" and "temperature is too high") are transmitted to the safety protection module.

[0124] The safety protection module sets multi-dimensional protection rules (such as SOC threshold, temperature threshold, and voltage fluctuation threshold), triggers protection actions and notifies the power switching module to cut off the circuit.

[0125] Composite protection conditions (SOC is too low, temperature is too high, or voltage fluctuates violently), any one of which triggers the protection mechanism. During the recovery phase, multi-parameter safety conditions are forcibly checked, and all conditions must be met at the same time for the check to be considered passed.

[0126] The power switching module controls the main circuit on / off (closing / opening the discharge circuit) according to control instructions and protection signals. During normal discharge, the circuit is closed according to the delay parameters; upon receiving a protection signal, the circuit is immediately opened and the recovery process begins.

[0127] The collaboration process between the above modules of the vehicle discharge system includes:

[0128] The load monitoring module collects load parameters in real time and determines the load status;

[0129] The adaptive delay control module calculates the delay parameters according to the load status and battery status and sends a control instruction to the power switching module;

[0130] The battery status monitoring module continuously monitors the battery safety status and notifies the safety protection module if protection is triggered;

[0131] After the safety protection module triggers the protection, it forcibly cuts off the circuit and notifies the adaptive delay control module to start the recovery process;

[0132] In the recovery phase, the adaptive delay control module executes the recovery strategy according to the fault type classification and gradually restores the discharge.
