BACKGROUND

[0002] With energy conservation and environmental protection and global policy support for electric vehicles, the current number of electric vehicles has increased significantly, and the number of electric vehicles (EV and PHEV) reached 3.5 million in 2021, accounting for 18% of narrow-sense passenger cars. The cumulative sales of electric vehicles accounted for 25% in 2020. The fire of electric vehicles has attracted widespread attention from consumers, and collision fire is one of the main factors of electric vehicle fire.

[0003] The current domestic C_NCAP introduces a 32kmph side column impact condition in the 2021 version to investigate the electrical safety of electric vehicles. The current mainstream collision electrical safety protection measures are to increase the energy absorption structure at the threshold and to strengthen the mechanical structure of the battery pack frame to reduce the extrusion of the battery cell. However, this method is prone to increase the cost and weight. In addition, some methods arrange battery cells with lower energy density and less prone to fire on the outside of the battery cell that is prone to extrusion, and arrange battery cells with high energy density in the area that is not prone to extrusion. However, this method will reduce the energy density of the battery pack and reduce the range. SUMMARY

[0011] In combination with the first aspect, in some optional embodiments, the simulation component determines the deformation data of the battery pack in the working condition through simulation analysis, and sets the basic SOC of the battery cell at different positions according to the deformation data.

[0012] In combination with the first aspect, in some optional embodiments, the monitoring component receives the basic SOC set by the simulation component and monitors the battery cell. When the SOC state of the battery cell with a smaller basic SOC reaches the basic SOC during charging of the battery pack, the monitoring component controls the adjustment component to charge the battery cell with a higher basic SOC to the battery cell with a smaller basic SOC.

[0013] In combination with the first aspect, in some optional embodiments, when the battery pack is charging, the SOC state of the battery cell with a higher basic SOC reaches the basic SOC, and the monitoring component controls the adjustment component to reversely excite the power of the battery cell with a higher basic SOC to the battery cell with a lower basic SOC whose SOC state reaches the basic SOC.

[0014] In combination with the first aspect, in some optional embodiments, when the battery is discharging, the adjustment component transmits a part of the discharging current of the battery cell in the area with a smaller basic SOC to the battery cell in the area with a larger basic SOC.

[0015] Secondly, the application provides a non-uniform charging and discharging control device, which is applied to a control equipment. The control equipment includes a battery pack, a monitoring component, an adjustment component, and a simulation component. The battery pack includes a plurality of battery cells. The monitoring component and the adjustment component are respectively electrically connected with the battery cells. The monitoring component and the adjustment component are in communication connection. The simulation component is electrically connected with the monitoring component. The control device includes:

[0016] A preset unit sets the basic SOC of the battery cell at different positions of the battery pack based on the simulation component.

When charging and discharging, the peripheral electric cores are preferentially charged and discharged to a relatively safe SOC state. In the case of collision and extrusion of the external electric cores, the application is less likely to catch fire. The method does not reduce the energy density of RESS. The vehicle collision electrical safety is improved without increasing the cost of the mechanical structure of the vehicle body. Compared with reducing the size of the electric core or strengthening the strength of the vehicle body, which brings cost and weight increase and reduces the endurance mileage, the application only needs to be controlled by software to achieve the purpose of reducing the risk of collision and fire.

[0034] The application will be described in detail below in combination with the drawings and specific embodiments. It should be noted that similar or identical parts are denoted by the same reference numerals in the drawings or description, and the implementation not shown or described in the drawings is in the form known to those skilled in the art. In addition, the direction terms mentioned in the embodiments, such as "up", "down", "top", "bottom", "left", "right", "front", "back", etc., are only the direction of the drawings and are not intended to limit the protection scope of the application.

[0035] As shown in Figure 6 The control device of the application includes a battery pack 100, a monitoring assembly 200, an adjusting assembly 300, a simulation simulation assembly 400 and a storage module. The battery pack 100 includes a plurality of battery cells 110. The monitoring assembly 200 and the adjusting assembly 300 are electrically connected with the battery cells 110 respectively. The monitoring assembly 200 and the adjusting assembly 300 are communicatively connected. The simulation simulation assembly 400 is electrically connected with the monitoring assembly 200.

[0036] In this embodiment, the battery pack 100 is formed by an array of a plurality of battery cells 110 and is mainly used for driving an electric vehicle. When the battery pack on the existing electric vehicle is impacted by external forces such as a car accident, the battery diaphragm is easily damaged, thereby causing a short circuit of the battery. When the battery is short-circuited, the heat generated by the battery will cause the battery to lose control and cause the entire battery pack 110 to gradually damage and burn.

[0037] The monitoring assembly 200 can be a BCM system (power control system) of a vehicle and can realize monitoring and data recording of each battery cell 110 in the battery pack 100. Specifically, the monitoring assembly 200 can monitor the SOC (state of charge) and SOH (State Of Health) of the battery cell 110 in real time and send the corresponding SOC state and SOH data of the battery cell 110 to the adjusting assembly 300.

[0038] The adjustment assembly 300 can be a reverse excitation circuit for adjusting the current direction of the battery cell 110 in a preset manner, so that the battery pack 100 is charged and discharged in a non-uniform manner. Unlike existing active balancing technology, which can balance the SOC of the battery cell, prolonging the life of the battery cell. The main purpose of the present application is to use the reverse excitation circuit to achieve that the external battery cell is in a lower SOC state most of the time during driving, thereby reducing the risk of collision and fire.

[0039] The control device further comprises a simulation assembly 400 for setting the basic SOC of the battery cell 110 at different positions on the battery pack 100. As Figure 1 In order to simulate the deformation of the battery pack 100 after the collision in a certain working condition using the simulation assembly 400, based on the simulation analysis results, the battery cell 110 with more serious deformation is defined as the external battery cell and set to a lower basic SOC, for example 60%; The basic SOC of some external battery cells 110 with slightly smaller deformation is set to 70; The battery cell 110 not easily deformed by collision is defined as the internal battery cell and set to a higher SOC, for example 100%; That is, the battery cell 110 on the battery pack 100 is from the outside to the inside, and the deformation data generated by the collision is gradually lower, and the basic SOC value of the corresponding battery cell 110 is also gradually increased. It is worth noting that the basic SOC is only a parameter information for triggering the reverse excitation circuit when the battery cell 110 reaches the preset value, and does not mean that the SOC state of the battery cell 110 can only be maintained at the basic SOC. The monitoring assembly 200 receives the basic SOC of each battery cell 110 set by the simulation assembly 400, and monitors the SOC state of each battery cell 110. Among them, the monitoring process will accurately collect the voltage, current and temperature of each battery cell, and adopt a modular price that can be expanded and reduced. In the present application, the BMS (Battery Management System) uses extended Kalman filtering and ampere-hour metering method to monitor the SOC of the single battery cell.

[0040] The storage module stores a computer program, which, when executed by the monitoring assembly 110 or the adjustment assembly 300, enables the control device to perform the corresponding steps in the following brake control method.

[0041] Please refer to Figure 2 and Figure 6 The present application also provides a non-uniform charging and discharging control method. The non-uniform charging and discharging control method can include the following steps:

[0042] S1: setting the basic SOC of the battery cell 110 at different positions on the battery pack 100 based on the simulation assembly 100;

[0043] S2: monitoring the SOC state of the battery cell 110 at different positions on the battery pack 100 based on the monitoring assembly 200;

[0044] S3: using the adjusting assembly 300 to unbalancedly adjust the power of the battery cell 110 based on the SOC state and the basic SOC.

[0045] In this embodiment, the adjusting assembly needs to realize 10A large current active balancing, and uses a peripheral reverse excitation circuit for active balancing, and realizes reverse charging and discharging between the internal battery cell and the external battery cell: in a high power state (such as greater than 50%), the charging speed of the internal battery cell is higher than that of the external battery cell; the discharge speed of the internal battery cell is lower than that of the external battery cell. In a low power state, balance discharge or balance battery cycle number according to battery life. The main purpose is to achieve that the external battery cell is in a lower SOC level most of the time during driving, and to reduce the risk of collision and fire.

[0046] The control method of unbalanced charging and discharging will be described in detail below:

[0047] In step S1, the basic SOC of the battery cell 110 at different positions on the battery pack 100 is set based on the simulation assembly 100. Based on the simulation results, when the battery pack 100 collides, the battery cell 110 at the edge is easy to deform due to direct collision and contact, and the deformation data is high, and the corresponding fire risk is also high; the battery cell 110 in the middle is not easy to deform due to the buffering of multiple battery cells 110 between the edge and the middle, and the corresponding deformation data is low, and the corresponding fire risk is also low. The deformation data can be a parameter reflecting the deformation degree of the battery cell 110. In this application, the basic SOC of the battery cell 110 with large deformation is set to a lower value, and the basic SOC of the battery cell 110 with low deformation is set to a higher value. That is, the corresponding basic SOC of the battery cell 110 gradually decreases from inside to outside. Preferably, the corresponding basic SOC of the battery cell 110 linearly decreases from inside to outside.

[0048] In step S2, the SOC state of the battery cell 110 at different positions on the battery pack 100 is monitored based on the monitoring assembly 200. The detection assembly 200 is used to monitor and store the voltage, current, temperature and SOC state of each battery cell 110 on the battery pack 100 and the basic value of each battery cell 110 set by the simulation assembly 400. When the SOC state of the battery cell 110 reaches the corresponding basic value, the adjusting assembly 300 is controlled to adjust the power of the battery cell.

[0049] In step S3, the SOC state and the base SOC control adjustment assembly 300 to regulate the power of the cell 110 based on the non-uniform. Specifically, in the battery pack 100 charging phase, all the power of the cell 110 will increase with the charging time, if all the SOC state of the cell 110 is lower than the base SOC, the adjustment assembly 300 does not act. During charging, the outer cell 110 at the edge due to the lower base SOC, the SOC state will first reach the base SOC, at this time the adjustment assembly 300 starts to work, using the reverse excitation circuit of LTC paving to actively unbalanced charging, charging changes as shown in Figure 3 The SOC state of the outer cell 110 reaching the base SOC will charge the inner cell whose SOC state has not reached the base SOC, that is, at this time most of the charging power of the outer cell 110 will be transferred to the inner cell 110. The transfer direction is from the cell 110 whose SOC state reaches the base SOC to the cell whose SOC state does not reach the base SOC. As Figure 4 The SOC state of the outer cell 110 reaching the base SOC will charge the inner cell whose SOC state has not reached the base SOC, that is, at this time most of the charging power of the outer cell 110 will be transferred to the inner cell 110. The transfer direction is from the cell 110 whose SOC state reaches the base SOC to the cell whose SOC state does not reach the base SOC. As

[0050] In the discharge phase of the battery pack 100, the power of all the cells will decrease with the discharge time, if all the SOC state of the cell is lower than the base SOC, the adjustment assembly 300 does not act. During discharging, the cell 110 at the middle position due to the lower base SOC, the SOC state will first be lower than the base SOC, at this time the adjustment assembly 300 starts to work, using the reverse excitation circuit of LTC paving to actively unbalanced charging, charging changes as shown in Figure 5 The SOC state of the outer cell 110 reaching the base SOC will charge the inner cell whose SOC state has not reached the base SOC, that is, at this time most of the charging power of the outer cell 110 will be transferred to the inner cell 110. The transfer direction is from the cell 110 whose SOC state reaches the base SOC to the cell whose SOC state does not reach the base SOC. As

[0051] The control method for unbalanced charge and discharge also includes active cycling of the number of cycles. When the number of unbalanced cycles of the power of some battery cells 110 (for example, external battery cells 110) is low, the adjustment component 300 will increase the number of cycles of the external battery cells 110 when the SOC state of the battery cells 110 has not reached the basic SOC, thereby increasing the number of cycles of the battery cells 110 with better SOH state (health state).

[0052] The present application also provides a control device for non-balanced charging and discharging. The braking control device 200 includes at least one software function module that can be stored in a storage module in the form of software or firmware, or embedded in the operating system (OS) of the control device. The monitoring component 200 and the adjustment component 300 are configured to execute the executable modules stored in the storage module, such as the software function modules and computer programs included in the control device.

[0053] The control device includes a preset unit 500, a monitoring unit 600, and an adjustment unit 700. The preset unit 500 is coupled to the simulation component 400. The monitoring unit 600 is coupled to the monitoring component 200. The adjustment unit 700 is coupled to the adjustment component. The functions of each unit may be as follows:

[0054] The preset unit 500 sets the basic SOC of the battery cells 110 at different positions on the battery pack 100 based on the simulation component 100;

[0055] The monitoring unit 600 monitors the SOC status of the battery cells 110 at different positions on the battery pack 100 based on the monitoring component 200;

[0056] The regulating unit 700 controls the regulating component 300 to perform non-balanced regulation on the power of the battery cell 110 based on the SOC state and the basic SOC.
