Detailed Description
The vehicle battery aging control system and the vehicle according to the present invention will be described in further detail with reference to the accompanying drawings and the specific embodiments. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the invention.
As described in the background art, since the vehicle storage battery is in an unsaturated and undercharged state for a long period of time during use, the battery aging speed is increased. This can result in an economic and time-consuming increase in the cost of replacing the battery due to the high cost of replacing the battery. The vehicle storage battery aging control system is provided for timely obtaining the aging state of the vehicle storage battery and reducing the aging speed in the use process of the vehicle storage battery.
Specifically, the vehicle storage battery aging control system of the embodiment of the application calculates aging values of related vehicle storage batteries under different charge states by using a battery aging model, and judges whether the vehicle storage batteries need to be charged according to the aging values, wherein when the aging values are larger than a first aging protection threshold, an instruction for executing full-load charging on the vehicle storage batteries is output. Therefore, the aging control system of the vehicle storage battery can obtain the aging values of the related vehicle storage battery under different charge states, is convenient for analyzing the influence of the charge states on the battery activity, judges whether the vehicle storage battery needs to be charged according to the aging values, timely charges the vehicle storage battery under full load, avoids the adverse influence of the long-term under-charge state, can reduce the aging speed of the vehicle storage battery, prolongs the service life, and realizes the purpose of preventing the battery aging. The vehicle battery aging control system according to the embodiment of the application is further described below.
Fig. 1 is a block diagram of a vehicle battery aging control system according to an embodiment of the present invention. Referring to fig. 1, in an embodiment, the vehicle battery aging control system 100 includes a data extraction module 110, an aging analysis module 120, and a charging control module 130, where the data extraction module 110 is configured to obtain a current charge percentage and output information of a related vehicle battery; the aging analysis module 120 is configured to obtain a current aging value of the vehicle storage battery by using the battery aging model when the current charge percentage and the output information of the vehicle storage battery meet a set condition; and the charging control module 130 is configured to output an instruction to perform full-load charging on the vehicle storage battery to a charging component when the aging value is greater than a first aging protection threshold.
Taking a 12V battery applied to an automobile as an auxiliary battery as an example, the data extraction module 110 may collect information about whether the automobile is in an operating state from an Engine Management System (EMS) of the automobile to which the 12V battery belongs, and may collect output information such as an actual charge percentage and an output current of the 12V battery from a battery sensor system (EBS). Since the 12V battery is operated only when the engine of the automobile is in an operating state, in order to improve the control efficiency, it may be provided that the aging value is calculated only when the engine is in an operating state by the aging analysis module 120, and the calculation state may be exited when the engine is stopped.
In one embodiment, the state of charge (or actual electric quantity, denoted as SOC) of the vehicle battery obtained by the data extraction module 110 may be expressed as a percentage, and the SOC may take a value ranging from 0% to 100%, where soc=0 indicates that the battery is completely discharged, and soc=100% indicates that the battery is full capacity. The data extraction module 110 may collect the real-time percentage of charge and output information of the vehicle battery according to a direct input instruction of a user, an instruction sent by the aging analysis module 120, or according to a set time interval.
The aging analysis module 120 is connected to the data extraction module 110, and can obtain the actual SOC and the output current of the 12V battery from the data extraction module 110, and after the determination, the actual SOC and the output current can be input to the battery aging model, and the calculated aging value can be obtained.
As an example, the aging analysis module 120 may include the following functional units: the device comprises a judging unit 121, a calculating unit 122 and a storage unit 123, wherein the judging unit 121 is used for judging whether the vehicle storage battery is in a working state or not, judging whether the current charge percentage of the vehicle storage battery is smaller than a charge aging threshold value or not, and when the current charge percentage of the vehicle storage battery is smaller than the charge aging threshold value, the judging unit 121 outputs an instruction for calculating the aging value; the calculating unit 122 is configured to receive the instruction for calculating the aging value output by the judging unit 121, input the current charge percentage of the vehicle storage battery into the battery aging model, and output the aging value calculated by the battery aging model; the storage unit 123 is configured to store the aging value calculated by the calculation unit 122. By storing the calculated aging value, subsequent calculation and analysis are facilitated. The charge aging threshold value can be specifically determined according to the structure and the output performance of the corresponding vehicle storage battery.
In one embodiment, the determining unit 121 may determine from three conditions that 1) the engine state is "running" 2) the EBS battery state is "reliable" and 3) the actual SOC of the 12V battery is less than the charge aging threshold, to obtain information about whether to start the calculating unit 122 to calculate the aging value. Only when these three conditions are satisfied simultaneously, an instruction to calculate the aging value may be output to the calculation unit 122. If any one of the conditions is not satisfied, the aging value calculation operation is not started, and when the updated input condition is received, the aging value calculation operation is judged to be started or not. For the corresponding device, "running" means that the vehicle battery is in an operating state, and "trusted" means that the battery state obtained from the EBS is accurate.
The calculation unit 122, upon receiving an instruction to calculate an aging value, inputs the received current charge percentage (SOC) into the battery aging model, and outputs the calculated aging value, which may be stored in the storage unit 123. The storage unit 123 may also store information such as the current time, the number of times, etc. processed by the calculation unit 122. In one embodiment, the aging values stored in the storage unit 123 include only the last calculated aging value, and when a new aging value is obtained by using the current charge percentage, the last calculated aging value is replaced with the new aging value. In one embodiment, the storage unit 123 may store the aging value obtained by each calculation and the corresponding percentage of charge, so as to analyze the association between the battery state of charge and the battery activity according to the data.
In one embodiment, the battery aging model adopted by the calculating unit 122 obtains the aging value corresponding to the current state of charge of the vehicle battery by accumulating the value of an integral function on the basis of the last aging value, wherein the value of the integral function is related to the current percentage of charge and the output current of the vehicle battery, and the initial value of the aging value is zero (i.e. the last aging value referred to in the first calculation is zero).
As an example, the battery aging model may calculate an aging value corresponding to the current percent charge of the vehicle battery by:
wherein, aging value_new is an Aging Value corresponding to the current charge percentage of the vehicle battery, aging value_old is the last (or last) Aging Value stored in the storage unit 123, Δsoc is a difference between the charge percentage (for example, 100%) of the battery in saturated state and the current charge percentage, K p is a proportionality coefficient representing the Aging influence degree, K I is an integral factor (integral factor) related to the current output current of the vehicle battery, and t is the time elapsed from the time when the Aging Value is zero to the current Aging Value.
The above-described proportional coefficient K p and integral coefficient K I may be obtained by experiment according to the output characteristics of the vehicle storage battery to which they are directed, and each of the proportional coefficient K p and integral coefficient K I may include a plurality of values corresponding to different states of charge of the battery, and may also be stored in the storage unit 123. For example, the scaling factor K p may be calculated from a time-varying curve of the battery SOC, and in the case of obtaining the current percentage of charge, K p corresponding thereto may be obtained from the time-varying curve of the battery SOC, with a larger SOC being larger K p. The integral coefficient K I can be calculated by a PID module, and can also be obtained by directly fitting MAP (SOC, I) which is a MAP set of the charge percentage SOC and the output current (I).
It can be seen that by using the battery aging model, the aging value of the vehicle storage battery in the working state is calculated by sequentially accumulating, and the calculated aging value is increased more than once without charging. Since the risk of permanent aging of the vehicle battery increases with the extension of the service time, in order to adjust the activity of the battery in time and reduce the risk of permanent aging without affecting normal use, the vehicle battery aging control system 100 according to the embodiment of the present invention further includes a charging control module 130, where the charging control module 130 may obtain the output information of the aging analysis module 120, and when the aging value calculated based on the current charge percentage is greater than the first aging protection threshold, an instruction for executing one full-load charging on the vehicle battery is output to the charging component. In one embodiment, the charge control module 130 sends a higher target voltage signal to the charging assembly via a control line (e.g., CAN or LIN) when the calculated aging value is greater than the first aging protection threshold. By full-load charging, the activity of the battery can be sufficiently activated, and the aging speed of the vehicular storage battery can be greatly reduced, compared with the case of a long-time under-powered state, thereby prolonging the life thereof.
The charging assembly may be an intelligent generator or a dc converter in a vehicle to which the vehicle battery belongs. The intelligent power generator can charge the vehicle storage battery according to the received target power generation voltage. The direct current converter can convert high-voltage electricity into low-voltage electricity according to the received target low-voltage to charge the vehicle storage battery. For example, the charge control module 130 may send the target voltage 12V to a dc converter, which after obtaining the signal, converts the high voltage to 12V and charges the 12V battery. The smart generator and the dc converter may be configured as disclosed.
Further, the charging control module 130 may be further configured to output an instruction to the charging component to perform a partial load charging on the vehicle battery when the aging value output by the aging analysis module 120 is greater than a second aging protection threshold, where the second aging protection threshold is less than the first aging protection threshold. The first aging protection threshold and the second aging protection threshold can be specifically set according to the structure and aging characteristics of the corresponding vehicle storage battery. When the partial load charging is executed, the charging control module 130 sends a balance target voltage signal lower than the full load charging to the charging assembly through the control line, so that the charging assembly performs the partial load charging on the vehicle storage battery, the purpose is to avoid that the aging value is larger than the first aging protection threshold value due to the fact that the load percentage of the vehicle storage battery is reduced too fast, the frequency of the full load charging of the charging assembly is reduced, the influence on other work of the charging assembly is small, and the permanent aging risk of the vehicle storage battery is reduced.
After completing the full-load charging, the SOC at this time may be set to 100% (an SOC value corresponding to the full capacity may be defined by user), and then the aging value is calculated to determine that a logic cycle of the full-load charging is completed, in order to continuously monitor the aging state of the battery during the subsequent battery operation and continuously determine whether the vehicle battery needs to be charged according to the aging value, referring to fig. 1, the aging analysis module 120 of an embodiment further includes a resetting unit 124, where the resetting unit 124 is configured to return the last aging value stored in the storage unit 123 to zero after executing the full-load charging on the vehicle battery. After the reset, in the subsequent operation of the same vehicle battery, the data extraction module 110, the aging analysis module 120 and the charging control module 130 may be used again to obtain the aging values of the same vehicle battery in different states of charge, and determine whether the vehicle battery needs to be charged according to the aging values (the full load charging and the partial load charging may be performed). In an embodiment, the reset unit 124 may also wait for the vehicle battery to operate for a period of time after completing one full-load charging, and then reset the vehicle battery, where the aging value is smaller during the period of time, and may not enter the calculation state. For example, when the current charge percentage of the vehicle storage battery is not less than a set value, resetting the latest aging value in the storage unit to zero, then sequentially performing integral accumulation calculation of the aging value by using the battery aging model, and judging whether the vehicle storage battery needs to be charged according to the aging value. In addition, in one embodiment, since the state of charge of the vehicle storage battery is provided by the battery sensor system (EBS), when the state of the battery sensor system is "unreliable" (there is a period of inaccurate output data when the EBS does not enter the steady operation state), the last aging value in the storage unit 123 is reset to zero, so that the determination of the aging value is performed again when the state of the battery sensor system is changed to "trusted".
Fig. 2 is a schematic flow chart of a vehicle battery aging control system according to an embodiment of the present invention. Referring to fig. 2, taking a 12V battery as an example, a process of calculating an aging value and judging and executing charging of the vehicle battery according to the aging value by using the vehicle battery aging control system according to an embodiment of the present invention is as follows:
First, acquiring actual condition information (engine state, 12V battery, SOC, output current of 12V battery, etc.) about the 12V battery provided by the engine management system and the battery sensor system may be performed by the above-described data extraction module 110;
next, judging whether the condition of the battery aging integration model is satisfied may be performed by the judging unit 121 in the aging analysis module 120 described above;
Then, after the calculation conditions are met, the battery aging value is calculated, and the aging values of the 12V battery with different histories can be accumulated based on the last aging value, specifically, the aging values can be executed by the calculation unit 122 in the aging analysis module 120 and stored in the storage unit 123, and the data stored in the storage unit 123 can be always kept and cannot be erased even after flameout and power failure;
then, after determining that the aging value of the 12V battery is greater than the first aging protection threshold, entering a full charge mode (full charge) may be performed by the charge control module 130;
then, when the SOC of the 12V battery is fully charged by full-load power generation, the aging value is reset to 0 after the actual SOC of the 12V battery is greater than the threshold value related to the aging value reset request, so that the next calculation can be performed by the above-described reset unit 124;
then, when it is determined that the aging value of the 12V battery is less than the second aging protection threshold, the partial load charging mode (PART CHARGE) is entered, which may be executed by the charging control module 130.
Therefore, through the process, an aging value calculation process of the aging influence of the 12V battery under different charge states can be established, and the calculation process fully considers the influence of the different charge states on the activity of the vehicle storage battery and finally reflects the aging value. According to the aging value, the charging mode of the battery is decided, the battery activity is activated, the aging speed is reduced, the aging protection of the vehicle storage battery is realized, and the service life of the vehicle storage battery can be prolonged.
It is to be understood that the vehicle battery aging control system of the embodiment of the present invention may include a plurality of computers, hardware, devices, etc. interconnected through a communication unit such as a network, or include a single computer, hardware, device, etc. having processes for implementing the present invention. The computer may include a Central Processing Unit (CPU), memory, and input and output components such as a keyboard, mouse, touch screen, display, etc. The modules and units (data extraction module, aging analysis module, charging control module, judgment unit, calculation unit, storage unit, and reset unit) in the vehicle battery aging control system may be combined in one module, or any one of the units may be split into a plurality of sub-units, or at least part of the functions of one or more of the units may be combined with at least part of the functions of other units and implemented in one module. According to an embodiment of the present invention, at least one of the respective units in the vehicle battery aging control system may be at least partially implemented as a hardware circuit, or may be implemented in hardware or firmware in any other reasonable manner of integrating or packaging the circuits, or at least one of the respective units in the vehicle battery aging control system may be at least partially implemented as a program code module which, when executed by a computer controlling the vehicle battery aging control system, may perform the functions of the respective module.
