Detailed Description
The present application will be described in further detail below with reference to the drawings and examples in order to make the objects, technical solutions, and advantages of the present application more apparent. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other technical solutions obtained by a person skilled in the art based on the embodiments of the present application fall within the scope of protection of the present application.
In the specific embodiment of the present application, the present application is explained by taking a lithium ion battery as an example of an electrochemical device, but the electrochemical device of the present application is not limited to a lithium ion battery.
The embodiment of the application provides an electrochemical device management method, as shown in fig. 1, comprising the following steps:
S101: and judging whether the communication information is sent in the period.
The execution subject of the embodiment of the present application may be a BMS (Battery MANAGEMENT SYSTEM). In the operation process of the electrochemical device, the BMS may manage the electrochemical device, for example, manage the state of the electrochemical device, and the BMS may manage one electrochemical device or may manage a plurality of electrochemical devices. The BMS may be integrated in the electrochemical device.
The electrochemical device may periodically transmit communication information to the external apparatus so that the external apparatus maintains communication with the electrochemical device, but communication between the electrochemical device and the external apparatus may be interrupted. It is understood that the communication information can be used to instruct the electrochemical device to be in communication with the external device, based on which the BMS can determine whether the communication information is transmitted during the period of the electrochemical device, for example, the BMS can detect whether a signal including the communication information is transmitted during the period of the electrochemical device to determine whether the electrochemical device successfully communicates with the external device.
The period of the embodiment of the present application may be set in advance, for example, one period may be any value between 0.1s and 5s, and specifically, one period may be 0.1s, 0.5s, 1s, 2s, 3s or 5s. The communication method between the electrochemical device and the external device is not particularly limited, and may be, for example, a communication method based on a CAN (Controller Area Network ) protocol or a communication method based on an RS485 bus protocol, and embodiments of the present application are not particularly limited. The external device may include a host computer or other server having data processing capability, and the host computer may have data storage capability, for example, may acquire and store information of the electrochemical device based on communication with the electrochemical device, so as to store communication data. The host computer may also have a display function, for example, the host computer may display the number of electrochemical devices currently establishing communication connection in its display interface for the user to view.
S102: in response to the successful transmission of the communication information, it is determined that the electrochemical device is in a communication state, and related data of the electrochemical device that has been successfully communicated is transmitted, so that the external device stores the related data.
In an embodiment of the present application, the related data of the electrochemical device may include data related to an operation State of the electrochemical device, and the operation State may include, but is not limited to, a charging voltage, a charging current, a discharging voltage, a discharging current, an SOC (State of Charge), an internal resistance, a temperature, and the like of the electrochemical device.
If the BMS determines that the electrochemical device successfully transmits the communication information, the BMS may determine that the electrochemical device is in a communication state, i.e., the electrochemical device has successfully communicated. Based on this, the electrochemical device may transmit the related data of the electrochemical device to the external apparatus, thereby causing the external apparatus to store the related data of the electrochemical device.
S103: in response to the unsuccessful transmission of the communication, continuing to determine whether to transmit the communication in the next cycle.
Because the electrochemical device can periodically send communication information to the external device, if the BMS determines that the electrochemical device does not successfully send communication information, which indicates that the electrochemical device is disconnected from the external device in the present period, the BMS can continuously determine whether to send communication information in the next period.
In one example, one period is 3s, if the electrochemical device does not successfully transmit communication information in the first period (0 s to 3 s), the BMS may continue to determine whether the electrochemical device transmits communication information in the second period (3 s to 6 s), and so on.
According to the management method for the electrochemical device, provided by the embodiment of the application, the BMS of the electrochemical device determines that the electrochemical device is in a communication state by judging whether communication information is sent in a period or not and responding to the successful sending of the communication information, and sends the related data of the electrochemical device which is successfully communicated, so that the external equipment stores and manages the related data. The embodiment of the application solves the problem of abnormal management data of the external equipment caused by the fact that the number of manual input connections is inconsistent with the actual number of parallel operation, and reduces the risk of data storage deficiency of the external equipment.
The present application also provides an electrochemical device management method, as shown in fig. 2, comprising:
S201: and judging whether the first communication information is reported in the period.
In the embodiment of the application, the electrochemical device may report communication information to the external device at intervals, where the communication information is first communication information, and the first communication information includes an identifier of the electrochemical device. In an exemplary embodiment, the plurality of electrochemical devices may report the first communication information to the host computer at intervals via the CAN bus, where the first communication information carries a unique ID (identity) of the electrochemical device, and when the host computer receives the first communication information and obtains the ID of the electrochemical device from the first communication information, the electrochemical device may be identified. The embodiment of the application has no special limitation on the form of the mark, and can be a character string, a serial number, a two-dimensional code or the like.
In one example, the electrochemical device may transmit communication information to the external apparatus every 500ms for one period of 3s, and the electrochemical device may transmit communication information to the external apparatus at most 6 times in one period, so long as the BMS determines that the electrochemical device successfully transmits communication information at least once within 3s, and the BMS may determine that the electrochemical device is in a communication state.
S202: determining that the electrochemical device which successfully reports the first communication information is in a communication state;
s203: and transmitting the related data of the electrochemical device which has successfully communicated.
If the electrochemical device successfully reports the first communication information, the BMS determines that the electrochemical device is in a communication state, i.e., the electrochemical device has successfully communicated. Based on this, the BMS may transmit the related data of the electrochemical device to the external device, thereby causing the external device to store the related data of the electrochemical device. The related data includes at least one of a voltage, a temperature, a current, alarm information or a switching state of the electrochemical device, wherein the alarm information may be alarm prompt information generated by the electrochemical device against abnormal conditions such as an over-high temperature condition, an under-low voltage condition, etc. during operation, and the switching state may be a state in which the electrochemical device charges or supplies power to a load. According to the embodiment of the application, the communication information is actively reported to the external equipment based on the period of the electrochemical device, the user does not need to manually input the information, the intelligent degree of the management of the electrochemical device is improved, the external equipment is enabled to store and manage the related data of the electrochemical device in time, and the risk of data storage deficiency of the external equipment is further reduced.
The present application also provides an electrochemical device management method, as shown in fig. 3, comprising:
S301: and judging whether the second communication information is successfully transmitted in the period.
In the embodiment of the application, the external device may send a response request to the electrochemical device, and after receiving the response request, the electrochemical device replies to the response request, that is, sends second communication information to the external device in a period, where the second communication information includes information replied to the response request sent by the external device. For example, the external device may send a response request to each electrochemical device one by one in a traversal manner based on the RS485 bus protocol, and each electrochemical device sends the second communication information to the external device in a period.
In one example, one cycle is 3s, the external device transmits a response request to one electrochemical device every 100ms, and 10 electrochemical devices in total transmit the response request, and the electrochemical devices need to return the second communication information within 3 s.
S302: determining that the electrochemical device that successfully transmits the second communication information is in a communication state;
S303: and transmitting the related data of the electrochemical device which has successfully communicated.
If the electrochemical device successfully transmits the second communication information, the BMS may determine that the electrochemical device is in a communication state, i.e., the electrochemical device has successfully communicated. Based on this, the BMS may transmit the related data of the electrochemical device to the external device, thereby causing the external device to store the related data of the electrochemical device. According to the embodiment of the application, the communication information of the electrochemical device is acquired based on the response request, and the BMS can realize finer management of the electrochemical device because the electrochemical device needs to respond to the response request. In addition, the external equipment stores and manages the related data of the electrochemical device in time, so that the risk of data storage deficiency of the external equipment is further reduced.
The present application also provides an electrochemical device management method, as shown in fig. 4, comprising:
s401: the main electrochemical device determines whether the third communication information is successfully transmitted within the period.
In an embodiment of the present application, the electrochemical device includes a master electrochemical device and a slave electrochemical device connected to the master electrochemical device, and the plurality of electrochemical devices may have a master-slave relationship, specifically, one master electrochemical device may have a communication capability with at least one slave electrochemical device, and the master electrochemical device may have a communication capability with an external device. The BMS of the master electrochemical device may acquire fourth communication information generated in the cycle of the slave electrochemical device, the external apparatus may transmit a response request to the master electrochemical device, and after the master electrochemical device receives the response request, the external apparatus may transmit third communication information including at least one fourth communication information generated in the cycle of the slave electrochemical device, based on which the external apparatus may acquire the fourth communication information of the slave electrochemical device.
S402: the main electrochemical device determines that the electrochemical device transmitting the fourth communication information is in a communication state;
s403: the primary electrochemical device transmits data regarding the electrochemical device that has successfully communicated.
If the slave electrochemical device successfully transmits the fourth communication message, the BMS of the master electrochemical device determines that the slave electrochemical device is in a communication state, i.e., the slave electrochemical device has successfully communicated. The BMS of the master electrochemical device may transmit the related data of the slave electrochemical device to the external device, thereby causing the external device to store the related data of the slave electrochemical device. According to the embodiment of the application, based on the master-slave structure of the electrochemical device, the master electrochemical device transmits communication information to the external equipment, and other slave electrochemical devices do not need to transmit communication information to the external equipment, so that the data transmission pressure between the electrochemical device and the communication link of the external equipment is reduced. In addition, the external equipment stores and manages the related data of the electrochemical device in time, so that the risk of data storage deficiency of the external equipment is further reduced. It should be noted that, for simplicity of description, it is sometimes described that the main electrochemical device performs a certain action, but it should be understood that the action is actually performed by the BMS of the main electrochemical device, that is, the execution subject of the embodiment of the present application may be the BMS of the main electrochemical device.
In one embodiment of the present application, before the main electrochemical device determines whether the third communication information is successfully transmitted in the period, the method further includes:
The method comprises the steps that a master electrochemical device acquires identification information reported by a plurality of slave electrochemical devices in a first period; the main electrochemical device transmits third communication information in the second period.
In the embodiment of the application, the slave electrochemical device can report the identification information to the master electrochemical device at intervals in the first period. In one example, the slave electrochemical device may report identification information to the master electrochemical device over the CAN bus at intervals during the first period, the identification information carrying a unique identification of the electrochemical device, such as a unique ID. After receiving the identification information reported from the slave electrochemical device, the master electrochemical device may send third communication information to the external apparatus in the second period, and when the external apparatus receives the third communication information and obtains the ID of the slave electrochemical device therefrom, the slave electrochemical device may be identified.
In one example, after the master electrochemical device receives the plurality of identification information reported from the slave electrochemical devices, the plurality of identification information may be aggregated, packaged into third communication information, and then the third communication information is transmitted. It is understood that the third communication information includes identification information of a plurality of slave electrochemical devices. The specific manner of information summarizing and packaging is known in the art, and the embodiment of the present application is not specifically limited. In addition, the lengths of the first period and the second period in the embodiment of the application are set according to actual needs and can be the same or different. According to the embodiment of the application, based on the master-slave structure of the electrochemical device, the master electrochemical device sends communication information to the external equipment, and other slave electrochemical devices do not need to report to the external equipment, so that the data transmission pressure between the electrochemical device and the communication link of the external equipment is reduced. And the communication information is reported to the main electrochemical device from the electrochemical device, so that the intelligent degree of the management of the electrochemical device is improved. In addition, the external equipment stores and manages the related data of the electrochemical device in time, so that the risk of data storage deficiency of the external equipment is further reduced.
In one embodiment of the present application, before the main electrochemical device determines whether the third communication information is successfully transmitted in the period, the method further includes:
The master electrochemical device forwards the response request to each slave electrochemical device; the master electrochemical device receives the response information replied to the response request by each slave electrochemical device in the first period, and transmits the third communication information in the second period.
In the embodiment of the application, the master electrochemical device may receive the response request sent by the external device, and forward the response request to the slave electrochemical device, where the slave electrochemical device may reply to the response request, send response information to the master electrochemical device in a first period, and after receiving the response information sent by the slave electrochemical device, the master electrochemical device may send third communication information to the external device in a second period. It is understood that the identification information may be included in the response information transmitted from the slave electrochemical device to the master electrochemical device as well, and thus the slave electrochemical device may be identified when the external apparatus receives the third communication information and obtains the ID of the slave electrochemical device therefrom.
In one example, after the master electrochemical device receives the response information sent by the plurality of slave electrochemical devices, the identification information of each slave electrochemical device may be obtained from the response information, the plurality of identification information may be summarized, packed into the third communication information, and then the third communication information may be sent. In addition, the lengths of the first period and the second period in the embodiment of the application are set according to actual needs and can be the same or different. According to the embodiment of the application, based on the master-slave structure of the electrochemical device, the master electrochemical device transmits communication information to the external equipment, and other slave electrochemical devices do not need to transmit communication information to the external equipment, so that the data transmission pressure between the electrochemical device and the communication link of the external equipment is reduced. Further, since the slave electrochemical device needs to respond to the response request, the BMS can implement more detailed management of the slave electrochemical device. In addition, the external equipment stores and manages the related data of the electrochemical device in time, so that the risk of data storage deficiency of the external equipment is further reduced.
In one embodiment of the application, the method further comprises: based on a change in the electrochemical device communicatively coupled to the external device, the external device is triggered to update and store the associated data.
This step may be located after step S102. It will be appreciated that the electrochemical device in communication with the external device is not stationary. In one example, there are originally 10 electrochemical devices communicatively connected to the external device, and after a while, if a batch of electrochemical devices is newly added, the number of electrochemical devices communicatively connected to the external device may exceed 10; in another example, if a part of the electrochemical devices communicatively connected to the external device is disconnected, the number of electrochemical devices communicatively connected to the external device may be less than 10. It can be seen that the electrochemical device in communication with the external device is in dynamic change. Based on the above, the embodiment of the application can trigger the external device to update and store the related data of the electrochemical devices when the electrochemical devices in communication connection with the external device are changed, for example, the number of the electrochemical devices is changed, so as to delete the data of the electrochemical devices which are disconnected in time, and save the storage space of the external storage device.
In one example, the external device may also update the number of electrochemical devices that have successfully communicated in its display interface, so that the user may view the status of the electrochemical devices that have successfully communicated in time, improving the user experience.
In one embodiment of the application, the method further comprises: the external equipment judges whether the electrochemical device which is successfully communicated has a management file, and responds to the management file, and the external equipment updates the related data of the electrochemical device in the management file; or, in response to the absence of the management file, the external device creates a management file of the electrochemical device and stores management data of the electrochemical device in the created management file.
The external device may set a management file for each electrochemical device, the management file storing data related to the electrochemical device. Since the electrochemical device in communication with the external device is in dynamic change, the electrochemical device which has previously established a communication connection with the external device will have a corresponding management file in the external device, whereas the electrochemical device which has not previously established a communication connection with the external device will not have a corresponding management file in the external device. On the other hand, the electrochemical device, which has previously established a communication connection with an external device, may have its related data changed, for example, its voltage, current, etc.
Based on the above, after receiving the related data of the electrochemical device, if the electrochemical device already has a corresponding management file, the external device can update the related data of the electrochemical device in the management file, which is beneficial to improving the real-time performance of data storage and is convenient for managing the electrochemical device in time; if the electrochemical device does not have a corresponding management file, the external device can newly establish a corresponding management file for the electrochemical device and store the related data of the electrochemical device therein, so that the electrochemical device can be managed in time.
