The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
First, a structure of a power battery system based on the present application will be explained:
the contactor data management method and device, the electronic device and the storage medium are suitable for managing the consumed life information of the contactor in the power battery system of the new energy automobile. As shown in fig. 1, which is a schematic structural diagram of a power battery system based on the embodiment of the present application, the power battery system mainly includes a contactor connected to a power battery, and a battery management system, where the battery management system includes a data storage module and a contactor data management device, and an RTE layer is disposed between the data storage module and the contactor data management device, and is used for performing data conversion in a communication process between the data storage module and the contactor data management device. The contactor data management device is located on a software application layer of the AUTOSAR framework, and the RTE is an intermediate layer in the AUTOSAR framework and is responsible for data interaction between the basic software layer and the software application layer. Specifically, the contactor data management device is used for acquiring the consumed life information of the contactor, writing the consumed life information into the data storage module, and simultaneously verifying the reliability of the data storage module in terms of data reading and data writing.
The embodiment of the application provides a contactor data management method, which is applied to a vehicle-mounted electric energy management system, wherein the vehicle-mounted electric energy management system comprises a data storage module and is used for managing the consumed life information of a contactor in a power battery system of a new energy automobile. The execution main body of the embodiment of the application is an electronic device, such as a server, a desktop computer, a notebook computer, a tablet computer, a single chip microcomputer and other electronic devices which can be used for managing the consumed life information of a contactor in a power battery system of a new energy automobile.
As shown in fig. 2, a schematic flowchart of a contactor data management method provided in an embodiment of the present application is shown, where the method includes:
The data storage module may be an NVM module in the vehicle-mounted power management system.
It should be noted that the current of the new energy automobile power battery needs to be output through the contactor, where the contactor plays a role of a switch. At present, the service life of a contactor is generally 100000 times, and the service life consumption times of the contactor are different due to different current value ranges. When monitoring the service life of the contactor, the initial information of the contactor is determined first, and the subsequent service life monitoring is performed on the contactor on the basis of the initial information, so that how to manage the initial information of the contactor is a non-negligible problem,
specifically, when the vehicle is started, initial information of the contactor is firstly read from the data storage module, and the initial information is the contactor life consumption information written after the vehicle is driven last time.
And step 203, judging whether the initial information is normally stored in the data storage module according to the checking result.
The contactor comprises a high-side contactor and a low-side contactor, initial information of the contactor comprises initial information of a main positive contactor and initial information of a main negative contactor of the high-side contactor, and initial information of a main positive contactor and initial information of a main negative contactor of the low-side contactor.
In order to adapt to the initialization process provided by the embodiment of the present application, the initial information and the reverse verification data in the data storage module may be stored in association in advance. Wherein, the reverse check data is obtained by performing reverse check on the initial information.
In both the high-side contactor and the low-side contactor, if the reverse verification value is set to [500000,500000], the initial information of the main positive contactor is referred to as PosLife, the initial information of the main negative contactor is referred to as NegLife, the reverse verification data corresponding to the initial information of the main positive contactor is referred to as PosLife opposition, and the reverse verification data corresponding to the initial information of the main positive contactor is referred to as NegLife opposition, the PosLife + PosLife opposition is referred to as 500000, and the NegLife + NegLife opposition is referred to as 500000.
Specifically, taking the high-side contactor as an example, the PosLife, NegLife, PosLife opposition and NegLife opposition of the high-side contactor are read from the data storage module, and the initial information and the reverse verification data of the main positive contactor and the main negative contactor are verified based on the reverse verification value to determine whether the currently read initial information and the reverse verification data are matched, so as to obtain a corresponding verification result. When the PosLife + PosLifeOpposition is not equal to 500000 or the NegLife + NegLifeOpposition is not equal to 500000, the initial information of the high-side contactor is determined to be abnormally stored in the data storage module, and an initialization abnormal fault of the data storage module can be reported.
In contrast, when PosLife + poslifeopposition is 500000 and NegLife + neglifeopposition is 500000, it is determined that the initial information of the high-side contactor is normally stored in the data storage module, and the subsequent process may be performed.
Further, when it is determined that the initial information is normally stored in the data storage module, the read initial information of the high-side contactor and the low-side contactor may be logically compared to obtain a maximum value, and the maximum value is stored in the data storage module to be used as the initial information representing the initial life consumption of the contactor.
And step 204, when the initial information is determined to be normally stored in the data storage module, acquiring the consumed life information of the contactor.
Wherein the consumed life information of the contactor is the number of times that the contactor is consumed currently. In practical applications, the contactor includes a high-side contactor and a low-side contactor, and the consumed life information of the contactor includes consumed life information of the high-side contactor and consumed life information of the low-side contactor.
Specifically, each contactor includes a main positive contactor and a main negative contactor; the consumed life information of the contactor includes consumed life information of a main positive contactor and consumed life information of a main negative contactor of the high-side contactor, and consumed life information of a main positive contactor and consumed life information of a main negative contactor of the high-side contactor.
The read latest written consumed life information is the consumed life information obtained in step 204.
And step 206, judging whether the writing process of the data storage module is normal or not according to the comparison condition between the reading result of the consumed life information and the recently written consumed life information.
Specifically, whether the read result and the written data are consistent may be determined according to a comparison result between the currently read consumed life information and the recently written consumed life information. If the data storage module is consistent with the data management module, determining that the writing process of the data storage module is normal, namely the reliability of the data management module in the aspect of data writing is higher; otherwise, it is determined that the writing process of the data storage module is abnormal, that is, the reliability of the data management module in terms of data writing is low. Meanwhile, the read data and the written data are checked in real time, so that the accuracy and the reliability of data management are ensured, and the problem of data writing faults is reduced.
Further, in an embodiment, when the writing process of the data storage module is abnormal, alarm information is generated to prompt a driver and other related personnel that the data storage module is abnormal in writing, and a writing fault exists.
On the basis of the foregoing embodiment, as an implementable manner, in an embodiment, the acquiring of the used life information of the contactor includes:
step 2011, obtaining current data of the contactor;
step 2012, determining the consumed life information of the contactor according to the current data of the contactor.
The current data is the current magnitude at the moment when the battery management system is powered off and the contactor is electrically disconnected.
It should be noted that, when the contactor is cut off with load, arcing, sticking, and the like of the contactor occur, and the service life of the contactor is shortened. Therefore, the service life condition of the contactor is calculated by detecting the current magnitude represented by the current data at the moment of opening the contactor.
Specifically, the number of consumed life times of the contactor may be calculated based on a preset detection model according to current data when the contactor is opened and attribute information of the contactor.
The attribute information of the contactor comprises the influence of different value ranges of current/voltage given by a contactor manufacturer on the service life times of the contactor.
Similarly, the elapsed life information of the contactor may also be directly detected based on the USD tool.
Accordingly, in an embodiment, before acquiring the information of the consumed life of the contactor, that is, before acquiring the current data of the contactor, the state of the contactor may be detected according to a preset detection period; when the state of the contactor is changed from the closed state to the open state, the step of acquiring the consumed life information of the contactor is performed.
Here, the detection period may be preset to 5ms, 10ms, or the like.
Specifically, when the state of the contactor is detected to be a closed state in the last detection period and the state of the contactor detected in the current detection period is an open state, that is, the state of the contactor is converted from the closed state to the open state, the current data of the contactor is acquired, and the information of the consumed life of the contactor is determined.
On the basis of the above embodiment, since the used lifetime of the contactor does not change when the contactor does not operate, in order to avoid wasting the storage space of the data storage module due to the repeated writing of the same information, as an implementable manner, in an embodiment, the method further includes:
step 301, judging whether the currently acquired consumed life information changes relative to the initial information;
and 302, if yes, writing the currently acquired consumed life information into the data storage module.
The last acquired consumed life information is the initial information.
On the contrary, if the currently acquired consumed life information is not changed from the initial information, the currently acquired consumed life information is not written into the data storage module, and the subsequent management process is not performed.
Exemplarily, as shown in fig. 3, a schematic overall flow chart of a contactor data management method provided in an embodiment of the present application is shown, where an NVM in fig. 3 is an NVM module and represents a data storage module, and the method shown in fig. 3 is an exemplary implementation manner of the method shown in fig. 2, and implementation principles of the two methods are the same and are not repeated.

According to the method provided by the scheme, the read initial information and the written consumed life information later are correspondingly verified, so that the data reading and data writing reliability of the data storage module is verified, and the accuracy of the initial information read by the battery management system and the accuracy of the written current consumed life information of the contactor are ensured.
