Detailed description of the invention
Fig. 1 show a kind of battery pack data communication system schematic diagram based on the embodiment of the present invention.
Specific embodiment
The present invention will be described with reference to embodiments.
Embodiment based on invention, a kind of battery pack data communication system as shown in Figure 1, data processing terminal, cell tube
Manage module, CAN bus unit and normal traffic unit, wherein the battery management module is used to obtain the operation information of battery,
The CAN bus unit is for connecting battery management module and data processing terminal, and the normal traffic unit is for obtaining electricity
The operation information in pond is simultaneously uploaded to data processing terminal；The battery management module is also used to mark critical data and non-key number
According to based on annotation management data transmission channel, the critical data is normality transmission, and non-critical data is interval transmission；It is described
Operation information of the data processing terminal based on pattern recognition process battery simultaneously exports process instruction.
Now, as the BCMS of rain of electrons/battery pack management system (battery cluster management system, i.e., the described battery management
Module) it have been relatively mature, the various parameters of single battery, while BAMS (battery heap manager are measured by various sensors
System, i.e. data processing terminal) as the level for receiving BCMS, also it is widely available application；Battery management module is used in this programme
In such as voltage, temperature, presence and the equilibrium state that obtain battery cell by various sensors, and entire battery cluster
The state of total voltage, total current, total SOC and alarm protective breaker etc.；In these data, a part of data are more important
Data because in battery system, single battery it is large number of, if whole single batteries is monitored, cost pole
Greatly, inefficient, therefore managed the data of whole (cluster battery) as crucial data, and will not be critical data
Part, one by one extract or selective extraction, by mark critical data, so that critical data is uploaded in time, make crucial number
(i.e. interrupted transmission) is transmitted according to for normality, non-critical data is interval transmission, meanwhile, by by critical data and threshold comparison
To judge the state (whether normal, the average data of generally preset threshold value or each battery cluster) of critical data, root
According to the state output process instruction of data, instruct for controlling battery pack and the battery pack data communication system.
The data processing terminal passes through the configuration of broadcast polling battery management module, and the configuration includes battery cluster
The address CAN and battery cell number.
The every 2s of data processing terminal removes the critical data and a battery management module of all battery management modules of linchpin
Non-critical data.Data processing terminal one powers on the configuration that will go broadcast polling battery management module, i.e., each cell tube
The address CAN of module is managed, how many packet has been hung below each cluster, how many a monomers has been hung below each packet, have received broadcast polling
Battery management module can respond immediately to, and such data processing terminal, which just can know that, has hung how many below present data processing terminal
Battery management module, the address CAN of each battery management module are how many.Broadcast issues when critical data is sent every time, non-
Critical data is intended for the battery management module of the known address CAN.Then according to frequency access evidence, pass is ensured that in this way
It is bound to get once in the every 2s of key data, if there is failure, is bound to protect in 2s.
The CAN bus unit is based on preset read access time, the critical data of acquisition all batteries cluster and wherein cluster
The non-critical data of battery cluster, marking the cluster battery cluster is to have read cluster, in next read access time, obtains all batteries cluster
The non-critical data of critical data and the non-battery cluster for having read cluster of cluster.
The frequency that critical data and non-critical data are read is different, and the data volume of critical data is fewer, and crucial number
According to extremely important, therefore critical data requires once get all clusters, i.e. the key of all clusters is first got in first 2s
Then data take the non-critical data of cluster, then first get the critical data of all clusters in second 2s, then remove cluster
Non-critical data will get the critical data of all clusters in that is, each 2s, but non-critical data is that poll takes.
The critical data includes total voltage, total current, total SOC and the operation shape for alerting protective breaker of battery cluster
State.
Operation data is divided into critical data and non-critical data, and critical data refers to the total voltage of this cluster, total current, total
The state of SOC and alarm protective breaker etc., these statistics indicate that the operation of battery cluster health status, as long as there is these data,
It may determine that whether system has exception, corresponding protection act is made in time, guarantees security of system.Non-critical data refers to pass
The unexpected battery data of key data, these data include voltage, temperature, presence and the equilibrium state of monomer, these information
The state of each battery core is characterized in more detail, can further judge the health status of system, is made accordingly more preferable
Each battery core of tactical management, guarantee whole system health operation.
The normal traffic unit is based on Ethernet and transmits data.
When the network interruption of normal traffic unit, since CAN communication is also being run, because two kinds communicate while failing general
Rate is extremely low, usually impossible, therefore critical data and non-critical data still can be got by upper layer, and system still is able to
It is carried out protecting accordingly in time according to the critical data got and other movements, guarantee operates normally.
Operation information of the data processing terminal based on pattern recognition process battery and packet the step of export process instruction
It includes: receiving the upload data of normal traffic unit, and mark it for normality data；The continued case of normality data is detected, if
There is exception in the transmission of normality data, then starts risk and exclude mode, which is used to be based on preset sets of threshold values and CAN bus
The operation information that unit uploads is compared and exports fault mode；It is read based on fault mode and exports process instruction.
System, generally can be with one of them for main data source, when this data source goes out to ask when handling data
When topic, it is rapidly switched to other spare data sources；This programme receives two data sources of processing simultaneously, is based on Ethernet
The normal traffic unit of transmission is main data source, persistently judges the abnormal feelings of normality data by detection data stream
Condition, when certain cluster battery cluster data or a certain partial data transmission quantity exception when, then simultaneously with CAN bus upload
Data are judgement basis to check that the battery of that a part goes wrong, and battery-based parameter judges it compared with threshold value
Then the type of affiliated failure reads solution according to fault type, solution includes some process instructions, such as defeated
It is out of order the position of battery and type, some measures taken such as terminates the use of certain section of battery.
The above, only presently preferred embodiments of the present invention, the invention is not limited to above embodiment, as long as
It reaches technical effect of the invention with identical means, all should belong to protection scope of the present invention.In protection model of the invention
Its technical solution and/or embodiment can have a variety of different modifications and variations in enclosing.
