In the above operating environment, embodiments of the present application provide an embodiment of a method of increasing energy of an energy storage system, it being noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system, such as a set of computer executable instructions, and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order other than that illustrated herein.

Fig. 2 is a flow chart of a method of increasing energy of an energy storage system according to an embodiment of the present application. As shown in fig. 2, the method may include the steps of:

in step S202, in response to the slave successfully connecting to the host, a first target request is sent to the host.

In the solution provided in step S202 of the present application, the first target request may be used to request that the slave increases the energy stored in the host, for example, the slave may include a flash battery, and the first target request may be used to indicate an addressing application sent from the slave to the host, and request addressing from the host.

In this embodiment, in response to the slave successfully connecting to the host, a first target request is sent to the host, e.g., a determination is made as to whether the slave successfully connects to the host, and if the slave successfully connects to the host, an addressing request is sent by the slave to the host, thereby requesting an increase in energy stored by the host using the slave.

Alternatively, in the case where the slave includes a flash battery, if the flash battery is successfully connected to the master, an addressing request is sent by the flash battery to the master, thereby requesting an increase in the energy stored by the master using the flash battery.

Alternatively, the master sets the connection detection signal link_check to a high level, and if the slave detects that the link_check is a high level, it is determined that the slave has been connected to the master, thereby transmitting an address application to the master through communication.

Step S204, obtaining first identification information sent by the host in response to the first target request.

In the technical solution provided in the above step S204 of the present invention, the first identification information may be used to indicate that the energy stored in the host is allowed to be increased by using the slave, and is used to identify the slave in at least one slave, for example, the first identification information may be addressing information obtained after the slave is effectively addressed by the host, where effective addressing is orderly addressing.

In this embodiment, after the slave successfully connects to the host and sends a first target request to the host, first identification information sent by the host in response to the first target request is acquired, for example, if the slave has sent an address application to the host, after the host effectively addresses the slave, address information corresponding to the slave is sent, so that the slave can acquire the address information.

Step S206, the first interface of the energy adding device in the slave machine is controlled to be connected with the target interface of the host machine based on the first identification information, and the working mode of the second interface of the energy adding device is switched from the slave machine mode to the host machine mode.

In the technical solution provided in step S206 of the present invention, the slave energy adding device may be configured to add the energy stored in the host, for example, the slave energy adding device may be an external expansion battery, the first interface may be a B interface of the external expansion battery, the target interface may be an interface of the host, and the second interface may be an a interface of the external expansion battery.

In this embodiment, the first interface may operate in a slave mode, the target interface may operate in a master mode, and the first interface and the second interface may have the same structural information and may be disposed at positions on the slave that are symmetrical to each other, for example, the first interface and the second interface may be designed indiscriminately, so that random plug-in use and mutual blind plug-in between the expansion battery and the master may be realized, and fool-proof design is not required.

Optionally, after acquiring the first identification information sent by the host in response to the first target request, controlling the first interface of the energy adding device in the slave to establish a connection with the target interface of the host based on the first identification information, and switching the operation mode of the second interface of the energy adding device from the slave mode to the host mode, for example, controlling the B interface of the external expansion battery in the slave to establish a connection with the interface of the host according to addressing information corresponding to the slave, so that the operation mode of the B interface of the external expansion battery remains in the slave mode, and switching the operation mode of the a interface of the external expansion battery from the slave mode to the host mode after the B interface of the external expansion battery detects the interface connected to the host.

Optionally, when one of the two interfaces of the external expansion battery pack detects an interface connected to the host, the interface is a slave interface, and the other interface of the external expansion battery pack is set as the host interface, and so on, the battery pack can be continuously expanded.

Optionally, the interface of the host and the interface of the external expansion battery pack can operate in a host mode and a slave mode, wherein the interface of the host operates in the host mode by default and the interface of the external expansion battery pack operates in the slave mode by default.

Step S208, outputting the target energy to the host based on the second interface in the host mode, the first interface in the slave mode and the target interface in the host mode, which are successfully connected.

In the solution provided in the above step S208 of the present invention, the target energy may be used to represent the total electric energy to be expanded.

In this embodiment, after the first interface of the energy adding device in the slave machine is controlled to establish a connection with the target interface of the host machine based on the first identification information, and the operation mode of the second interface of the energy adding device is switched from the slave machine mode to the host machine mode, the target energy is output to the host machine based on the second interface in the host machine mode, and the first interface in the slave machine mode and the target interface in the host machine mode that are successfully connected, for example, according to the a interface of the expansion battery in the host machine mode, and the B interface of the expansion battery in the slave machine mode that are successfully connected and the interface of the host machine, the expansion of the total electric energy can be performed by using the expansion battery to output the target energy to the host machine, which is only exemplified herein and is not limited in detail.

In the related art, the master is usually fixedly connected to the output port of the slave, and the input port of the slave expands the output port of the other battery pack, and this serial connection manner results in that the wiring must be fixed. If the same input port and output port are used for the external expansion battery pack, the risk of damaging equipment due to misplacement exists, and the fool-proof design is performed by adopting two different connectors, so that the cost is increased. In addition, the host can also be directly connected with a plurality of battery packs, the connection mode is limited by the expansion number of the battery packs of the host, and the switch path of the battery management system in the host can also be increased along with the increase of the number of interfaces, so that the hardware cost of the host is further increased, and the technical problem of high energy increasing cost of the energy storage system exists. For example, fig. 3 (a) is a schematic diagram of a connection manner between a master and a slave according to the related art, as shown in fig. 3 (a), the master is fixedly connected to an output port of the slave, and an input port of the slave expands output ports of other battery packs, and this serial connection manner results in that wiring must be fixed, and if the expanded battery packs use the same input and output ports, there is a risk of damaging equipment due to misplacement. To solve such a problem, a fool-proof design may be performed using two different connectors, but the design causes an increase in cost and inconvenience in wiring.

Fig. 3 (b) is a schematic diagram of another connection method between a master and a slave according to the related art, as shown in fig. 3 (b), the master is directly connected to a plurality of Battery packs, the connection method is limited by the number of Battery pack extensions of the master, and the switch paths of a Battery Management System (BMS) in the master also increase with the increase of the number of interfaces, thereby causing the hardware cost of the master to increase.

However, in the solution implemented in steps S202 to S208 of the present application, it is determined whether the slave is successfully connected to the host, if the slave is successfully connected to the host, a first target request is sent to the host to request to increase energy stored in the host by using the slave, and first identification information sent by the host in response to the first target request is obtained, according to the first identification information, a connection between a first interface of an energy increasing device in the slave and a target interface of the host is controlled, and an operation mode of a second interface of the energy increasing device is switched from the slave mode to the host mode, and according to the second interface in the host mode and the first interface in the slave mode and the target interface in the host mode, which are successfully connected, target energy is output to the host.

The above-described method of this embodiment is further described below.

As an alternative embodiment, the first interface is any one of the interfaces in the energy adding device, the second interface is an interface other than the first interface in the interfaces, and the default operation mode of the interface is the slave mode and allows switching from the slave mode to the master mode.

Optionally, the first interface may be any one of a plurality of interfaces in the expansion battery, and the second interface may be an interface other than the first interface in the plurality of interfaces in the expansion battery, where the energy increasing device may be any one of the plurality of expansion batteries, so as to achieve a technical effect that duplex or half duplex differential communication may be used to increase energy for the energy storage system.

Optionally, the host includes an external expansion battery pack interface, the external expansion battery pack includes two external expansion battery pack interfaces, and the external expansion battery pack interfaces are all designed indiscriminately, and can be connected with the host or the slave.

Alternatively, if the energy adding device is the expansion battery 1, the B interface of the expansion battery 1 is a first interface of the energy adding device, and the a interface of the expansion battery 1 is a second interface of the energy adding device, which is only illustrated herein and not specifically limited.

In this embodiment, the power expansion of the host is required by connecting a plurality of external expansion batteries, and how to perform the power expansion of the host by connecting a plurality of external expansion batteries is further described below.

In this embodiment, the second target request may be used to request that the energy stored in the host be increased by the first slave, the second identification information may be used to indicate that the energy stored in the host is allowed to be increased by the first slave, and used to identify the first slave in at least one slave, the third interface may be the same as the structural information of the fourth interface and may be disposed at positions symmetrical to each other on the first slave, for example, as shown in fig. 5 (a), the first slave may include the external expansion battery 2, the first slave energy increasing device may be the external expansion battery 2, the third interface may be the a interface of the external expansion battery 2, and the fourth interface may be the B interface of the external expansion battery 2, which is merely illustrated herein, and is not limited in detail.

Optionally, after the a interface of the external expansion battery 2 detects that the a interface is connected to the external expansion battery 1, the working mode of the B interface of the external expansion battery 2 is switched from the slave mode to the host mode, and according to the B interface of the external expansion battery 2 in the host mode, and the a interface of the external expansion battery 1 in the host mode and the a interface of the external expansion battery 2 in the slave mode, which are successfully connected, the external expansion battery 2 can be used to output target energy to the host, so that the technical effect that the host can be subjected to electric energy capacity expansion by connecting a plurality of external expansion batteries is achieved.

In this embodiment, there is a need to continuously expand the battery pack in the energy storage system, and how to continuously expand the battery pack in the energy storage system is further described below.

In this embodiment, the first slave may comprise an upstream battery pack connected to the master, the second slave may comprise a downstream battery pack connected to the master, for example the second slave may comprise a scalable battery 3.

Optionally, after the operation mode of the fourth interface of the energy adding device in the first slave is switched from the slave mode to the master mode, it is determined whether the slave includes a next second slave corresponding to the first slave, if the slave includes a next second slave corresponding to the first slave, the second slave is determined as the first slave, the fourth interface is determined as the second interface, and then the following steps are performed: judging whether the first slave machine is successfully connected to the host machine or not, if the first slave machine is successfully connected to the host machine, sending an addressing application to the host machine by the first slave machine, and after the host machine effectively addresses the first slave machine, sending addressing information corresponding to the first slave machine until at least one slave machine is the last slave machine in at least one slave machine, thereby achieving the technical effect of continuously expanding battery packs in the energy storage system.
