When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.
It will be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, refer to an orientation or positional relationship illustrated in the drawings for convenience in describing the present application and to simplify description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present application.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.
The battery monitoring data storage method is mainly suitable for application scenarios of a battery management system for monitoring battery operation, and is particularly suitable for scenarios requiring operation monitoring and fault diagnosis of a battery, for example, scenarios requiring storage of charging and discharging data and fault data of the battery so as to provide effective and massive data for operation and fault analysis of the battery at any time.
Fig. 1 shows a specific flowchart of a battery monitoring data storage method provided in a first aspect of an embodiment of the present application, and for convenience of description, only the relevant portions of the embodiment are shown, which are detailed as follows:
the battery monitoring data storage method in the embodiment includes:
step S100: collecting current operation data of the battery, wherein the current operation data comprises at least one battery working parameter;
it is understood that the battery operating parameter includes at least one of voltage, current, temperature, and state of charge. The current operation data includes charge and discharge data and/or abnormal data, wherein battery operating parameters of the charge and discharge data include voltage, current, temperature, State of charge (SOC), and the like of the battery in a charge and discharge State. The battery working parameters of the abnormal data comprise voltage, current, temperature, state of charge and the like of the battery under the fault types of overvoltage, undervoltage, overcurrent, overtemperature and the like. The abnormal data may be determined by comparing the currently collected charge and discharge data with a standard threshold, for example, after collecting the actual voltage of the battery, comparing the actual voltage with the standard voltage threshold, and outputting the abnormal data representing that the battery is in overvoltage or undervoltage when the actual voltage is greater than or less than the standard voltage threshold. Further, the abnormal data also comprises an abnormal grade, and the abnormal grade is determined by the difference value of the actual charging and discharging data of the battery and a standard threshold value.
It will be appreciated that the battery may be a lithium battery or the like type of power battery, or other battery that requires monitoring.
Step S200: judging whether the difference value between at least one battery working parameter in the current operation data and a reference working parameter is out of a target range, wherein the reference working parameter is the battery working parameter written into the nonvolatile memory last time;
it is understood that the battery operating parameter includes at least one of voltage, current, temperature, and state of charge. Different battery operating parameters correspond to different reference operating parameters, i.e. voltage is compared with a reference voltage, current is compared with a reference current, temperature is compared with a reference temperature, and state of charge is compared with a reference state of charge. The reference operating parameter is a battery operating parameter last written into the nonvolatile memory, that is, a battery operating parameter carried in current operating data last written into the nonvolatile memory. In the method for storing battery monitoring data in this embodiment, when a difference between any one of the battery operating parameters of the current operating data and the reference operating parameter exceeds a target range, it is determined that the current operating data changes compared with the current operating data written last time. Optionally, in other embodiments, it may also be set whether a combination of any two or more battery operating parameters changes simultaneously according to requirements, so as to determine whether to write the current operating data.
It will be appreciated that the target range may be adjusted accordingly based on the capacity of the non-volatile memory, data granularity requirements. The target range for each different type of cell operating parameter and its reference operating parameter may be set differently, for example, the target range for voltage variation may be +/-100mV, the target range for current variation may be +/-200mA, and the target range for temperature variation may be +/-0.5 degrees.
It is understood that the nonvolatile Memory may be a Flash Memory (Flash Memory), a Read-only Memory (ROM), a Programmable Read-only Memory (PROM), an Electrically alterable Read-only Memory (ear ROM), an Erasable Programmable Read-only Memory (EPROM), or an Electrically Erasable Programmable Read-only Memory (EEPROM).
Step S300: and if the difference value between at least one battery working parameter in the current operation data and the reference working parameter is out of the target range, writing the current operation data serving as operation record data into a target position of the nonvolatile memory, and updating the reference working parameter.
It will be appreciated that the target location is a write address. The operation log data includes at least one of a time point, charge and discharge data or abnormal data associated with the time point, and a serial number associated with the operation log data written last time. The time point is the time when the data is acquired, and the time point comprises specific time information such as year, month, day, hour, minute, second and the like. The serial numbers of different types of operation record data can be sorted separately, namely the serial numbers carried by the charge and discharge data and the abnormal data are two different serial numbers, so that different data types are distinguished. When writing a piece of operation record data, the sequence number carried by the operation record data is added to the sequence number of the last operation record data.
It is to be understood that, after the current operation data is written as operation record data to the target location of the nonvolatile memory, the reference operation parameters are updated to the respective battery operation parameters included in the operation record data.
It is understood that when the difference between at least one battery operating parameter of the current operation data and the reference operating parameter is outside the target range, the current operation data is changed from the last written operation record data. The battery monitoring data storage method in the embodiment continuously collects the current operation data of the battery, and only writes in the current operation data of which the working parameter of a certain battery changes to a certain extent compared with the reference working parameter, so that the battery is continuously monitored in the whole time period, the redundant repeated operation data are prevented from being written in, unnecessary waste of the capacity of a storage is reduced, a large amount of effective operation data can be stored, and a large amount of effective data can be provided for analyzing the operation and fault diagnosis of the battery.
In one embodiment, when the storage address of the nonvolatile memory is full, the address of the running record data with the minimum sequence number in all the running record data stored in the nonvolatile memory is used as a target position, and the current running data to be written is written into the target position and covers the running record data with the minimum sequence number.
It will be appreciated that when the non-volatile memory is full, the newly written rollback to the start address of the non-volatile memory overwrites the oldest record with the new record, thereby causing the non-volatile memory to store valid recent operating data.
Referring to fig. 2, in an embodiment, the method for storing battery monitoring data further includes:
step S400: scanning all sectors of the non-volatile memory;
it is understood that all sectors of the nonvolatile memory in the present embodiment are used for storing the operation log data. In other embodiments, a portion of the sectors may be selected for storing the operation log data.
Step S500: counting the effective record quantity of each operation record data, and determining the address of the operation record data with the maximum serial number in each operation record data;
it will be appreciated that the running record data may be validated by being recorded with fixed format and verification data.
Step S600: dynamically constructing a file header according to the effective record number and the address of the running record data with the maximum serial number, and storing the file header in a Random Access Memory (RAM);
it will be appreciated that the header includes the number of active records, the write address of the next new run record data, and the sequence number of the next new run record data.
It is understood that the header is updated every time a new run record is written.
It is understood that each piece of the operation record data carries a sequence number, and the value of the sequence number is increased when one piece of the operation record data is added. And comparing the serial number size relationship of the operation record data to obtain the address of the operation record data with the maximum serial number, and calculating the next address behind the address as the position for writing the next operation record data.
Step S700: and writing the current running data as running record data into a target position of the nonvolatile memory according to the file header.
It is understood that the target location is the write address of the next new run record data.
It is appreciated that non-volatile memory has read and write lifetime limitations. The file header records key information such as the effective record number, the write address of the next new run record data, the serial number of the next new run record data, and the like, and the file header needs to be updated every time a new run record data is written. The file header is generally stored in the nonvolatile memory, so that the number of reading and writing times of the sector of the nonvolatile memory storing the file header is far greater than that of other ordinary sectors, and the reading and writing life of the sector is a short plate of the whole nonvolatile memory. In the method for storing battery monitoring data in this embodiment, only the operation record data is stored in the nonvolatile memory, and the file header is stored in the random access memory, so that the nonvolatile memory does not have the problem of the read-write life of a certain sector due to frequent reading, and the access speed of the random access memory is faster than that of the nonvolatile memory. And the file header is dynamically constructed by scanning the nonvolatile memory, so that the problem of volatile data of the random access memory due to power failure is solved.
It CAN be understood that the above-mentioned battery monitoring data storage method is applied to a battery management system, and an external host CAN obtain each operation record data stored in a nonvolatile memory of the battery management system through CAN communication, serial communication, LAN communication, and the like. For example:
the battery management system receives the synchronization time sent by the host computer to synchronize the internal time with the host computer;
acquiring a general condition command for acquiring the running record data sent by the host, and replying a data packet containing the effective record quantity, the starting record time and the ending record time of the running record data to the host;
and acquiring a command of the operation record data of the specified time point sent by the host, and replying the operation record data corresponding to the time point to the host.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
