Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the present disclosure. One skilled in the relevant art will recognize, however, that the aspects of the disclosure may be practiced without one or more of the specific details, or with other methods, components, devices, steps, etc. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.

The flow diagrams depicted in the figures are exemplary only and not necessarily all steps are included. For example, some steps may be decomposed, and some steps may be combined or partially combined, so that the order of actual execution may be changed according to actual situations. In addition, all of the following terms "first," "second," "third," etc. are used for distinguishing purposes only and should not be taken as a limitation of the present disclosure.

Aiming at the energy storage equipment of the battery energy storage system, other equipment or systems cannot directly access under the condition that IO is exclusively used, and the connection can be established only by releasing the original resources. In addition, IO access must be through a local connection, remote data communication cannot be achieved, and in the case that internal energy storage devices need to be debugged, a debug engineer needs to arrive at the site.

Furthermore, the configuration of the parameters of the IO connection must be adjusted according to the actual IO attributes. When multiple drives are connected, the IO resources need to be opened or closed, consuming a lot of time and memory.

In summary, the problem of poor data communication performance of the energy storage device in the existing energy storage system generally exists, and the performance of the battery energy storage system is further affected.

To solve or at least alleviate the above-mentioned technical problem, the embodiments of the present disclosure provide a new data communication scheme applied to an energy storage system in which an internal energy storage device communicates with an external device.

Fig. 1 schematically illustrates a schematic diagram of an energy storage system according to an embodiment of the present disclosure. Referring to fig. 1, the energy storage system may include an external device, a proxy service unit, and a target energy storage device.

The energy storage device referred to in this disclosure may also be referred to as an internal energy storage device, which may be any device in a battery energy storage system, including, but not limited to, a battery management system (Battery Management System, BMS), an energy storage converter (Power Conversion System, PCS), an energy management system (Energy Management System, EMS), an air conditioner, and the like, for example. The target energy storage device may be any one of the energy storage devices included in the energy storage system.

The battery management system can also be called a battery nurse or a battery manager and mainly comprises a detection module, a control module, a communication module and the like. The main function of the system is to monitor and control the state of the battery in real time, including but not limited to the parameters of the battery such as voltage, current, temperature, SOC (state of charge) and the like. Meanwhile, the battery management system can also perform protection control on the battery, such as overcharge, overdischarge, overcurrent and the like, so that the safety and the service life of the battery are ensured.

The energy storage converter mainly comprises an inverter, a transformer, a controller and the like, and is equipment for converting electric energy stored by a battery into alternating current and supplying the alternating current to a power grid or a user side. The main functions of the energy storage converter include converting direct current into alternating current, controlling input and output of electric energy, and ensuring safety and stability of the system. The performance of the energy storage converter directly affects the operating efficiency and the service life of the battery energy storage system.

The energy management system is responsible for the control strategy of the battery energy storage system, and the control strategy can influence the decay rate and the cycle life of the battery in the system, so that the energy storage economy is determined. In addition, the energy management system can monitor faults in the running process of the system, and plays roles of protecting equipment in time and guaranteeing safety.

The target energy storage device of the present disclosure supports IO communication modes such as RS485, CAN, RS232, and the like.

The external device may be a device for commissioning and controlling the target energy storage device, that is, in embodiments of the present disclosure, a commissioner may monitor, control, etc. the target energy storage device by means of the external device. The present disclosure does not limit the device type of the external device, such as a server, a monitoring device, a personal computer, a smart phone, a tablet computer, and the like.

The proxy service element may be a software element for enabling data communication between the external device and the internal energy storage device. The proxy service unit may be configured, for example, in a server system of the energy storage cabinet, to which the present disclosure is not limited.

In the energy storage system of the present disclosure, the proxy service unit may be configured to perform data communication with an external device through a virtual network interface that is virtual in advance, and perform data communication with a target energy storage device through an IO communication manner.

Therefore, the external equipment does not need to know specific connection parameters of the energy storage equipment, the flexibility of data transmission and the expansibility of the equipment are improved, the problem of low data transmission efficiency caused by the exclusive characteristic of the IO communication mode is solved to a certain extent, and the data transmission performance of the energy storage equipment is improved. In addition, based on the configuration of the virtual network interface, data communication between the remote external equipment and the energy storage equipment can be realized, and no distance limitation exists between the external equipment and the energy storage equipment, so that the remote control of the energy storage equipment is facilitated.

In particular, the virtual network interface may be a network interface based on the TCP/UDP protocol.

TCP (Transmission Control Protocol ) and UDP (User Datagram Protocol, user datagram protocol) are the core of the TCP/IP protocol. TCP defines the format of data and acknowledgement information exchanged for reliable transmission between multiple computers, as well as the actions taken by the computers to ensure proper arrival of the data. The protocol specifies how TCP software recognizes how multiple destination processes on a given computer recover from packet repetition such errors. The protocol also specifies how two computers initialize a TCP data stream transmission and how to end this transmission. The biggest feature of TCP is to provide connection-oriented, reliable byte stream services. UDP is a simple datagram-oriented transport layer protocol. Non-connection-oriented, unreliable data streaming is provided. UDP does not provide reliability nor functions such as message arrival confirmation, sequencing, and flow control. It simply sends datagrams that the application passes to the IP layer, but there is no guarantee that they will reach the destination. The message may be lost, repeated, out of order, etc. However, UDP does not establish a connection between the client and the server before transmitting the datagram, and there is no mechanism such as timeout retransmission, so the transmission speed is fast.

It should be noted that the virtual network interface of the embodiments of the present disclosure is a TCP/UDP protocol based network interface, which is only an exemplary description, and may also be constructed based on other protocols, including, but not limited to, IPX/SPX protocols, netBEUI protocols, and the like.

The number of energy storage devices included in the energy storage system may be one or more. The following describes a data communication process of a target energy storage device in the energy storage device in connection with the energy storage system. The target energy storage device may be any one of the energy storage devices included in the energy storage system.

The proxy service unit may be configured to determine a current operating state of the target energy storage device in response to a target energy storage command sent by the external device. Transmitting a target energy storage command to the target energy storage device under the condition that the current working state of the target energy storage device is an idle state; under the condition that the current working state of the target energy storage equipment is an occupied state, if the target energy storage command does not exist in a target command pool uniquely corresponding to the target energy storage equipment, adding the target energy storage command into the target command pool; wherein, in the case that the energy storage system comprises a plurality of energy storage devices, each energy storage device is uniquely corresponding to a command pool; after the working state of the target energy storage equipment is switched from the occupied state to the idle state, if the target command pool contains a plurality of energy storage commands, the energy storage commands in the target command pool are sent to the target energy storage equipment one by one according to the order of the command priority from high to low.

The target energy storage device may be configured to receive an energy storage command and perform an operation corresponding to the energy storage command in a case where the current operating state is an idle state.

Referring to fig. 2, the external devices may include external devices 1, …, external device p, and the energy storage devices may include energy storage device 1, energy storage device 2, …, and energy storage device q. Wherein, p and q are positive integers, and p may be equal to q or not.

In the case of an energy storage system comprising a plurality of external devices, these external devices may be in data communication with the energy storage device simultaneously via the proxy service unit. For example, referring to fig. 2, the external device 1, …, the external device p may connect any one of the energy storage devices 1, 2, …, q simultaneously via the proxy service unit.

The process of an energy storage device comprising a plurality of external devices, each in data communication with the same target energy storage device, is described below in connection with an energy storage system.

Multiple external devices may be used to send the target energy storage commands separately. In some embodiments, these external devices may send the target energy storage command at the same time. Each target energy storage command is used for indicating the target energy storage device to execute the operation corresponding to each target energy storage command.

The proxy service unit may be configured to receive a plurality of target energy storage commands sent by a plurality of external devices, and add the plurality of target energy storage commands to a target command pool uniquely corresponding to the target energy storage devices; wherein, in the case that the energy storage system comprises a plurality of energy storage devices, each energy storage device is uniquely corresponding to a command pool; and under the condition that the working state of the target energy storage equipment is an idle state, the energy storage commands in the target command pool are sent to the target energy storage equipment one by one according to the order of the command priority from high to low.

The target energy storage device may be configured to receive an energy storage command sent by the proxy service unit and perform an operation corresponding to the energy storage command in a case where the working state is an idle state.

In addition to the proxy server element being configured independently of the external device and the energy storage device, in other embodiments, the proxy server element may be configured within the energy storage device, or referred to as nested within the energy storage device.

Referring to fig. 3, the proxy service units may be configured in internal energy storage devices, so that each energy storage device corresponds to an individual service, and the problem that when only one proxy service unit is configured in the system, the proxy service unit hangs up to affect data communication of other energy storage devices is avoided.

In addition, as can be seen from fig. 3, based on the data communication scheme of the embodiment of the disclosure, multiple external devices can be simultaneously connected with the same energy storage device, so that the problem that only single-wire connection is supported in the IO communication mode in the existing scheme to cause IO monopolization is avoided, and the data communication performance of the energy storage device is improved.

Based on the configuration of the energy storage system described above, a data communication method according to an embodiment of the present disclosure will be described below.

That is, in the case that the current working state of the target energy storage device is an idle state, the proxy service unit may send the target energy storage command to the target energy storage device through the manner of IO communication.

S46, under the condition that the current working state of the target energy storage equipment is an occupied state, if no target energy storage command exists in a target command pool uniquely corresponding to the target energy storage equipment, adding the target energy storage command into the target command pool; where the energy storage system includes a plurality of energy storage devices, each energy storage device uniquely corresponds to a command pool.

The proxy service unit maintains a command pool for each energy storage device, and when the energy storage command cannot be processed because the energy storage device is in an occupied state, the proxy service unit can temporarily store the received energy storage command into the command pool corresponding to the energy storage device. In the embodiment of the disclosure, the command pool uniquely corresponding to the target energy storage device is recorded as a target command pool.

For the stored energy commands in the command pool, command priorities may be preconfigured. That is, in the embodiment of the present disclosure, each energy storage command corresponds to an attribute of command priority, and the energy storage command with high priority is processed preferentially, and the energy storage command with low priority is processed later. The command priority level of one energy storage command may be manually set in advance, which is not limited by the present disclosure.

In the case that the current operating state of the target energy storage device is the occupied state, the proxy service unit may determine whether the target energy storage command exists in a target command pool uniquely corresponding to the target energy storage device.

According to some embodiments of the present disclosure, there are no target energy storage commands in the target command pool. In this case, the proxy service unit may add the target energy storage command to the target command pool.

According to further embodiments of the present disclosure, there are target energy storage commands in the target command pool. In this case, in order to avoid repeated execution of the same task or an error in the algorithm logic, the proxy service unit may discard the currently received target energy storage command and raise the command priority of the target energy storage command in the target command pool.

Specifically, the proxy service unit may determine the number of times the target energy storage command is received during the period that the target command pool includes the target energy storage command, and determine the priority lifting amplitude according to the number of times the target energy storage command is received. And then, the command priority of the target energy storage command in the target command pool is promoted according to the priority promotion amplitude.

It should be noted that, during the period that the target command pool contains the target energy storage command, the number of times of receiving the target energy storage command is in positive correlation with the priority lifting amplitude. That is, the more times the target energy storage command is received, the greater the current demand for the command is, the greater the priority lifting amplitude is; the fewer the number of times of the received target energy storage command, the smaller the current demand for the command, and the smaller the priority lifting amplitude.

In addition, after the target energy storage command is transmitted to the target energy storage device, if the target energy storage command is received again, the command priority of the target energy storage command is the originally set priority, not just the priority after the priority is raised by the amplitude.

S48, after the working state of the target energy storage equipment is switched from the occupied state to the idle state, if the target command pool contains a plurality of energy storage commands, the energy storage commands in the target command pool are sent to the target energy storage equipment one by one according to the order of the command priority from high to low.

And the target command pool comprises m energy storage commands which are ordered from high to low according to the command priority. After the working state of the target energy storage device is switched from the occupied state to the idle state, the proxy service unit can send the energy storage commands in the target command pool to the target energy storage device one by one according to the order of the command priority from high to low. That is, the energy storage command with high command priority is sent to the target energy storage device first, and the energy storage command with low command priority is sent to the target energy storage device after that.

Regarding the transmission manner, as described in step S44, the proxy service unit may transmit the energy storage command to the target energy storage device one by one through the manner of IO communication.

Specifically, the proxy service unit may switch from the occupied state to the idle state in response to the working state of the target energy storage device, and send an ith energy storage command of the m energy storage commands to the target energy storage device. And when the target energy storage equipment executes the operation corresponding to the ith energy storage command, the target energy storage equipment is in an occupied state.

The proxy service unit may transmit the (i+1) th energy storage command of the m energy storage commands to the target energy storage device in case that the target energy storage device is switched from the occupied state to the idle state after performing the operation corresponding to the (i) th energy storage command.

It is understood that the (i+1) th energy storage command is an energy storage command having a command priority next to the (i) th energy storage command among the m energy storage commands. Wherein, m and i are positive integers, and the value range of i is [1, m-1].

It will be appreciated that in the process of sending the commands in the target command pool to the target energy storage device one by one, if a new energy storage command is added to the target command pool, the above-described process may be re-executed, and the command priority order of the energy storage commands in the target command pool may be updated.

In addition, for the process that the proxy service unit determines the energy storage device corresponding to the received energy storage command according to the received energy storage command, the present disclosure may be implemented in the following manner.

In the case that the energy storage system of the embodiment of the disclosure includes a plurality of energy storage devices, the target energy storage command may include an identifier of the target energy storage device, so that the proxy service unit may determine, from the plurality of energy storage devices of the energy storage system, the target energy storage device corresponding to the target energy storage command according to the identifier, and send the target energy storage command to the target energy storage device through an IO communication manner. The present disclosure does not limit the type of the identifier, and may be a predefined character, a name of the energy storage device, etc.

In addition, in the case that the energy storage system of the embodiment of the disclosure includes a plurality of energy storage devices, the proxy service unit may determine, according to data characteristics of the target energy storage command, the target energy storage device from the plurality of energy storage devices, and send the target energy storage command to the target energy storage device through an IO communication manner.

Specifically, the proxy service unit may perform feature extraction on the target energy storage command, and determine the energy storage device as the target energy storage device under the condition that the extracted feature is matched with a feature corresponding to the energy storage device.

For example, in the case where the energy storage device includes a battery management system and an energy storage converter, if the feature extracted by the proxy service unit from the target energy storage command is "adjust charging power of the energy storage cabinet to XXX", the proxy service unit determines through semantic analysis that the feature corresponds to the energy storage converter, and thus the proxy service unit transmits the target energy storage command to the energy storage converter. The mapping relationship between the features and the energy storage devices may be pre-constructed, and after the feature is extracted by the proxy service unit, the mapping relationship may be analyzed to determine the energy storage device corresponding to the target energy storage command.

Referring to fig. 5, remote commands of the external device are issued to the proxy service unit, the proxy service unit acquires the commands by means of the virtual network interface, the commands form a task queue according to priority, and the proxy service unit issues the commands according to the order from high priority to low priority, wherein the commands are sequentially transmitted to the target energy storage device through the IO interface service.

After the target energy storage device executes the task corresponding to the command, the processing result is fed back to the external device through the IO interface service and the virtual network interface of the proxy service unit, and the feedback data is uploaded.

For example, during a predetermined period of time, the proxy service unit obtains 10 energy storage commands from the external device, the energy storage commands are reordered in the proxy service unit according to priority, and the energy storage command with high priority is delivered to the target energy storage device first.

By configuring the command priority, the processing mode of the task is optimized, so that the task with high priority can be processed in time.

After the target energy storage device processes the target energy storage command, the target energy storage device may generate feedback data, where the feedback data may be execution result data generated after the target energy storage device performs an operation corresponding to the target energy storage command. The proxy service unit can acquire the feedback data from the target energy storage device in an IO communication mode, and sends the feedback data to the external device through the virtual network interface. The external device may be an external device that transmits the target energy storage command, or may be another external device, for example, an external device that performs feedback result recording and/or statistics.

In addition, the external device can perform visual display on the received feedback data so as to be convenient for relevant personnel to check.

Referring to fig. 6, first, an external device may transmit a device parameter adjustment command, and a proxy service unit may acquire the device parameter adjustment command by means of a virtual network interface and transmit the device parameter adjustment command to a target energy storage device through an IO communication manner. The target energy storage device may then adjust its own parameters based on the device parameter adjustment command and generate a parameter adjustment result. And then, the target energy storage device feeds back a parameter adjustment result to the proxy service unit in an IO communication mode, and the proxy service unit feeds back the parameter adjustment result to the external device based on the virtual network interface.

Referring to fig. 7, first, an external device may transmit a device status monitoring command, and a proxy service unit may acquire the device status monitoring command by means of a virtual network interface and transmit the device status monitoring command to a target energy storage device through IO communication. Next, the target energy storage device may determine device status data based on the device status monitoring command. For example, the device status monitor command indicates that device status data of the last week is invoked, which may include, but is not limited to, device on/off information, temperature information, power information, exception information, and the like. And then, the target energy storage device feeds back device state data to the proxy service unit in an IO communication mode, and the proxy service unit feeds back the device state data to the external device based on the virtual network interface.

Fig. 8 illustrates a schematic diagram of upgrading a target energy storage device using a data communication scheme of an embodiment of the present disclosure.

Referring to fig. 8, first, an external device may transmit a device upgrade command, which may include upgrade-related instructions and an upgrade data packet. The proxy service unit can acquire the device upgrade command by means of the virtual network interface and send the device upgrade command to the target energy storage device in an IO communication mode. Next, the target energy storage device may upgrade its own system based on the device upgrade command and generate a device upgrade result. For example, the device upgrade result may include an upgraded system version number. And then, the target energy storage device feeds back a device upgrading result to the proxy service unit in an IO communication mode, and the proxy service unit feeds back the device upgrading result to the external device based on the virtual network interface.
