[0002] Sodium ion battery is a secondary battery. Its working principle is mainly based on the movement of sodium ions between the positive and negative electrodes. During the charging and discharging process of sodium ion battery, sodium ions will be embedded and released back and forth between the two electrodes. The car starting battery is mainly used to start the vehicle's engine. It can provide large current in a short time to ensure smooth ignition and start of the engine. In addition, the car starting battery is also responsible for powering other electronic equipment of the vehicle, such as lights, audio and other systems.

[0003] Currently, the starting battery power control of fuel vehicles usually relies on the output power of the vehicle engine and the actual speed of the vehicle for regulation. However, when the vehicle is not in use, it is easy to cause the starting battery to be insufficient, resulting in a significant drop in the battery discharge power.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a sodium ion automobile starting battery high rate discharge system, including: a collection monitoring module, an analysis module, a power control module, a mode control module and an early warning module.

[0007] The data acquisition module is used to collect physical parameter information of different cycles of the car's starting battery, engine information and user's daily vehicle usage habits, and then transmit the information to the analysis module after pre-processing.

[0008] The analysis module receives the data packets transmitted by the collection and monitoring module, uses the abnormal analysis unit to analyze the physical parameters of the starting battery in different cycles, transmits the obtained battery risk value F and power value S to the early warning module and the power control module, and sends the engine information to the power control module. The user analysis unit analyzes the user habit information, obtains the starting basic value H1, the remaining usage average H2, the entertainment media usage average H3, and then transmits the obtained user energy consumption average C to the battery control module.

[0009] The battery control module generates control signals and transmits these signals to the mode control module continuously.

[0010] The mode control module is responsible for dynamically adjusting the engine power according to dynamic signals.

The preprocessed data will be packaged into information packets in a standard format, and the above information will be transmitted to the analysis module through a high-speed data transmission interface.

[0014] Preferably, the analysis module includes an abnormality analysis unit and a user analysis unit;

[0015] The abnormality analysis unit performs periodic analysis on various physical parameters of the battery according to a preset time period, and compares the physical parameters of the battery with the normal working range. When a parameter deviates from the normal range, the abnormal parameter value is obtained according to the formula, and the voltage abnormal value, current abnormal value, temperature abnormal value, and internal impedance abnormal value distribution are marked as O, P, I, and N. The abnormal value range is 0 to 1. The battery risk value is obtained through the formula, and the abnormal value is compared with two thresholds to generate a safety signal, and the serious warning signal and the emergency warning signal are transmitted to the early warning module.

[0029] Preferably, the mode control module is responsible for dynamically adjusting the engine power output. When a hold signal is received, the engine power output is not changed. When the mode control module receives a power failure signal, the fuel injection amount and the engine speed are increased to improve the engine power output.

[0030] Preferably, after receiving the battery status signal, the early warning module only saves the safety signal. When receiving a serious warning signal and an emergency alarm signal, the driver is notified through the display and voice system to make an emergency stop. Based on the long-term battery usage data and abnormal value data, a battery health report is generated and pushed to the driver from time to time.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1:

[0043] See also Figure 1 The present application provides a sodium ion automobile starting battery high-rate discharge system, including a collection and monitoring module, an analysis module, a power control module, a mode control module and an early warning module.

[0044] The data acquisition module is used to collect physical parameter information of different cycles of the car's starting battery, engine information and user's daily vehicle usage habits, and then transmit the information to the analysis module after pre-processing.

[0045] The analysis module receives the data packets transmitted by the collection and monitoring module, uses the abnormal analysis unit to analyze the physical parameters of the starting battery in different cycles, transmits the obtained battery risk value F and power value S to the early warning module and the power control module, and sends the engine information to the power control module.

[0046] The battery control module generates control signals and transmits these signals to the mode control module continuously.

[0047] The mode control module is responsible for dynamically adjusting the engine power according to dynamic signals.

[0048] The early warning module is responsible for receiving battery status signals, retaining safety signals according to signal classification, notifying the driver of serious warnings and emergency alarm signals through display and voice, and generating battery health reports and sending them to the driver from time to time.

[0049] The data acquisition module includes a battery acquisition unit, an engine acquisition unit, a user habit acquisition unit and a preprocessing unit. The battery acquisition unit continuously monitors the physical parameter information of the car's starting battery in different cycles. The engine acquisition unit intermittently collects engine information. The user habit acquisition unit collects user's daily vehicle usage habits, usage cycle and time, and then transmits the above information to the preprocessing unit.

[0050] The main monitored physical parameters include:

[0051] Voltage: Usually should be kept within a certain range (such as 12V to 14V).

[0052] Current: The battery's charge and discharge current should also be kept within a set range (e.g. -10A to +10A).

[0053] Temperature: The temperature of the battery needs to be within a safe range, usually between 0°C and 45°C.

[0054] Internal impedance: The internal impedance of a battery can reflect its health. High impedance may mean that the battery is old or damaged.

[0055] The preprocessing unit will filter the noise of the battery information and then correct the data to eliminate data deviations caused by equipment errors, environmental changes, etc. It will compress and aggregate high-frequency data such as battery current and voltage, and convert them into smaller information packets that are easier to transmit. The preprocessed data will be packaged into information packets in a standard format, and the above information will be transmitted to the analysis module through a high-speed data transmission interface.

[0056] The analysis module includes an abnormality analysis unit and a user analysis unit;

[0057] The user analysis unit analyzes the user's habits, obtains the average power consumed by the lights and other electrical equipment during vehicle driving, marks it as the remaining usage average H2, and calculates the user's entertainment media usage energy consumption average H3 according to the formula, and obtains the user's energy consumption average C according to the formula, and transmits the above information and engine information to the power control module;

[0058] The user analysis unit calculates the average energy consumption H2 of entertainment media use through the following formula. The specific calculation formula is as follows:

[0059]

[0060] The user analysis unit calculates the user's average energy consumption C through the following formula. The specific calculation formula is as follows:

[0061] C=H1+H2×M1+H3×M2

[0062] Among them, the starting basic value H1 refers to the minimum power required for engine starting and vehicle electronic system initialization, which is preset and fixed. M1 represents the weight coefficient of the remaining usage averages, and M2 represents the weight coefficient of the average energy consumption of entertainment media usage.

[0063] The battery control module performs a subtraction operation on the battery charge value S and the user's energy consumption average C to calculate the charging difference J. When the charging difference J is less than the evaluation threshold, a power shortage signal is generated. When the charging difference J is greater than or equal to the evaluation threshold, a hold signal is generated and these signals are continuously transmitted to the mode control module.

[0064] The mode control module is responsible for dynamically adjusting the engine power output. When a hold signal is received, the engine power output is not changed. When a power failure signal is received, the mode control module increases the fuel injection amount and engine speed to improve the engine power output.

[0065] After receiving the battery status signal, the early warning module only saves the safety signal. When receiving serious warning signals and emergency alarm signals, it notifies the driver to make an emergency stop through the display and voice system. Based on the long-term battery usage data and abnormal value data, it generates a battery health report and pushes it to the driver from time to time.

[0066] Specific workflow:

[0067] The acquisition and monitoring module collects battery physical information from the car's starting battery, collects engine information from the car's engine and collects user usage information, and transmits the battery physical information, user usage information and engine information to the analysis module for analysis, obtains the user's energy consumption average C and battery power value S and transmits them to the power control module, obtains the engine speed information and transmits it to the mode control module, the power control module calculates the charging difference J and generates a corresponding control signal based on the charging difference J and transmits it to the mode control module, and the mode control module dynamically adjusts the engine power according to these signals.

[0068] The analysis module includes an abnormality analysis unit and a user analysis unit;

[0069] Furthermore, the present invention calculates the difference charging difference J between the battery power value S and the user energy consumption average C through the battery control module, and generates a corresponding control signal according to the charging difference J and transmits it to the mode control module, thereby regulating the engine power so that the battery power value S is always higher than the user energy consumption average C, and the battery can maintain sufficient power, ensuring that the starting battery has enough electrical energy for high-rate discharge, and ensuring that the vehicle has stable and reliable battery support during startup and operation.

[0070] Embodiment 2:

[0071] The abnormality analysis unit performs periodic analysis on various physical parameters of the battery according to a preset time period, and compares the physical parameters of the battery with the normal working range. When a parameter deviates from the normal range, the abnormal parameter value is obtained according to the formula, and the abnormal voltage value, abnormal current value, abnormal temperature value, and abnormal internal impedance value distribution are marked as O, P, I, and N. The abnormal value range is 0 to 1. The battery risk value is obtained through the formula, and the abnormal value is compared with the two thresholds to generate a safety signal. The serious warning signal and the emergency warning signal are transmitted to the early warning module.

[0072] The abnormal analysis module obtains the calculation formulas for abnormal voltage values, abnormal current values, abnormal temperature values, and abnormal internal impedance values ​​as follows: where P represents the value of each parameter.

[0073]

[0074] The abnormal analysis module calculates the battery risk value F according to the formula. The specific formula is as follows:

[0075] F=O×X1+P×X2+I×X3+N×X4

[0076] Among them, O represents the voltage abnormal value, P represents the current abnormal value, I represents the temperature abnormal value, N represents the internal impedance abnormal value, X1 represents the weight coefficient of the voltage abnormal value, X2 represents the weight coefficient of the current abnormal value, X3 represents the weight coefficient of the temperature abnormal value, and X4 represents the weight coefficient of the internal impedance abnormal value.

[0077] The abnormal analysis unit compares the battery risk value with the warning threshold. When the battery risk value is less than warning threshold 1, a safety signal is generated. When the battery risk value is greater than warning threshold 1 and less than warning threshold 2, a serious warning signal is generated. When the battery risk value is greater than warning threshold 2, an emergency alarm signal is generated. The above signal is marked as a battery status signal and transmitted to the early warning module.

[0078] Warning threshold 1: This threshold is usually set at 0.5. When the abnormal value is close to 0.5, it means that a parameter of the battery begins to deviate from the normal range. The system believes that the battery may face certain risks, but this deviation will not immediately affect its function.

[0079] Warning threshold 2: This threshold is usually set at 0.8. When the abnormal value is close to 0.8, it means that a parameter of the battery is significantly deviated from the normal range, and the battery may face more serious risks, such as performance degradation or potential failure.

[0080] The specific method of the automobile starting battery discharge system is as follows:

[0081] S1. The acquisition monitoring module is responsible for collecting information about the car's starting battery, engine operation and user usage habits, and transmits it to the analysis module after preprocessing.

The user analysis unit analyzes the user's habits to obtain the user's average energy consumption C. According to the battery risk value F, the corresponding battery status signal is generated and transmitted to the early warning module, and the user's average energy consumption C is transmitted to the battery control module.

[0085] S5. The early warning module notifies the driver of emergency stop through display and voice of serious warning and emergency alarm signals in the battery status signal, and generates a battery health report and pushes it to the driver.

[0086] Specific workflow:

[0087] The acquisition monitoring module collects battery physical information from the car's starting battery, and transmits the battery physical information to the analysis module after being processed by the preprocessing unit. The analysis module analyzes and processes the battery physical information to obtain abnormal values ​​of various parameters and the battery risk value F, and transmits the abnormal values ​​of various parameters and the battery risk value F to the early warning module to produce a battery health report, and generates a battery status signal based on the battery risk value F and transmits it to the early warning module.

[0088] Furthermore, the present invention analyzes the physical parameters of the starting battery in different cycles through an abnormal analysis unit, thereby monitoring the working status of the battery. When these parameters deviate from the normal range, the abnormal analysis unit calculates the battery risk value F and determines whether the starting battery is in an abnormal state according to the change of the battery risk value F, and sends different battery status signals to the driver. The monitoring and abnormal judgment mechanism can effectively improve the safety of battery use, thereby improving the safety of the vehicle and reducing the risk of accidents caused by battery failure.
