The wireless communication system 12 is capable of receiving and transmitting wireless signals. The coding system 13 may address the battery management system 11. The external battery management system address information may be address information generated by other battery management modules, and when the wireless communication system 12 receives the external battery management system address information, the corresponding battery management system is addressed according to the received external battery management system address information, so as to form local battery management system address information different from the external battery management system address information, so that each battery management system corresponds to a different address. Alternatively, the encoding system may also self-encode the local battery management system address information when there is no external battery management system address information. The local battery management system address information may be, for example, external battery management system address information plus a logical 1, although other addressing schemes are possible. After the addressing of the local battery management system is completed, the address information of the local battery management system is sent to the outside through the wireless communication module and is used as the address information of the external battery management system of the subsequent battery management module. According to the analysis, the battery management module of the embodiment can automatically address, does not need to additionally configure a dial switch, does not need to additionally configure a BMS system, and has the advantages of being simple and efficient in addressing mode, simple in cost and the like.
According to the technical scheme of the embodiment, the adopted battery management module comprises a battery management system, a wireless communication system and a coding system; the coding system is electrically connected with the battery management system and the wireless communication system; the wireless communication system is used for receiving the address information of the external battery management system and sending the address information of the local battery management system; the coding system is used for coding the local battery management system address information according to the external battery management system address information or obtaining the local battery management system address information from the coding.

Illustratively, the encoding system may be a single chip microcomputer or an FPGA or the like.
Illustratively, the wireless communication system 12 includes a wireless transmitting unit and a wireless receiving unit for receiving external battery management system address information; the wireless transmitting unit is used for transmitting the local battery management system address information to the outside.
Specifically, each battery management module is provided with a wireless transmitting unit and a wireless receiving unit. The wireless transmitting unit of the battery management module is communicated with the wireless receiving units of other battery management modules; also, the wireless receiving unit of the battery management module communicates with the wireless transmitting units of other battery management modules. The wireless transmitting unit may be, for example, an infrared wireless transmitting unit, and the wireless receiving unit may be, for example, an infrared wireless receiving unit.
Optionally, fig. 2 is a schematic circuit diagram of another battery management module according to an embodiment of the present utility model, and referring to fig. 2, the battery management module further includes a self-coding unit 14, where the self-coding unit 14 is communicatively connected to the coding system 13; the self-encoding unit 14 is configured to transmit a self-encoded signal to the encoding system in response to an external instruction; the encoding system 13 is configured to self-encode the local battery management system address information in response to the self-encoded signal.
Specifically, when the battery management module does not receive the external battery management system address information, an external instruction may be sent to the self-encoding unit 14 in other manners, so that the self-encoding unit generates a self-encoding signal to the encoding system, and further, the encoding system is enabled to encode and form the local battery management system address information. The situation that the battery management module cannot generate the address information of the local battery management system is prevented. Illustratively, the self-encoding unit 14 may be a push-button switch and the local battery management system address information generated by the encoding system in response to the self-encoding signal may be a preset address. When the key switch 14 is preset, the corresponding coding system 13 may be reset, so that the coding system 13 assigns the address of the battery management system 11 to a preset address, which may be "000001", for example. It should be noted that, the number of bits of the preset address may be set according to the total number of battery management modules, which is not particularly limited in this embodiment. The preset operation may be, for example, a long press for a preset time or longer to prevent erroneous operation. The preset time is, for example, 5 seconds.
The embodiment of the utility model also provides a battery management device, as shown in fig. 3, fig. 3 is a schematic circuit structure diagram of the battery management device provided by the embodiment of the utility model, and the battery management device comprises the battery management module provided by any embodiment of the utility model. Because the battery management device provided by the embodiment of the utility model includes the battery management module provided by any embodiment of the utility model, the battery management device also has the same beneficial effects, and is not described herein again.
Optionally, with continued reference to fig. 3, the wireless communication system includes a wireless receiving unit 121 and a wireless transmitting unit 122; the wireless receiving unit 121 is used for receiving external battery management system address information; the wireless transmitting unit 122 is used for transmitting the local battery management system address information to the outside; the wireless receiving unit 121 of any one battery management module 1 corresponds to only the wireless transmitting unit 122 of one battery management module 1.
Specifically, in this embodiment, each battery management module 1 includes a wireless transmitting unit and a wireless receiving unit. When the wireless transmitting unit 121 receives the external battery management system address information, the encoding system addresses the local battery management system according to the external battery management system address information, and sets the address as the local battery management system address information, wherein the local battery management system address information may be the external battery management system address information plus logic 1. Then, the wireless transmitting unit sends the address information of the local battery management system to the wireless receiving unit of the next battery management module, so that the battery management modules in the battery management device can be addressed in sequence. And the address of each battery management module is different due to the adoption of an incremental addressing mode. In addition, as shown in the above analysis, if the wireless receiving unit in the battery management module receives the address information of a plurality of external battery management systems, the encoding system can address for a plurality of times, so that the address cannot be determined. Thus, the present embodiment sets each wireless receiving unit 121 to receive only the signal transmitted by one wireless transmitting unit 122, wherein the signal transmitted by the wireless transmitting unit 122 in the other battery management modules is received, so that each battery management module can be correctly addressed.
Illustratively, as shown in fig. 3, in two adjacent battery management modules 1, the wireless transmitting unit 122 of one battery management module is opposite to the wireless receiving unit 121 of the other battery management module 1. Wherein, the meaning of facing is that the signal transmitted by the wireless transmitting unit 122 can be directly incident on the wireless receiving unit 121. By the arrangement, on one hand, the wireless receiving unit 121 can receive stronger signals, and the occurrence of signal loss is prevented; on the other hand, it is also possible to avoid the wireless transmitting unit 122 from transmitting signals to other areas so that other wireless receiving units receive signals.
Illustratively, as shown in fig. 3, the wireless receiving unit 121 and the wireless transmitting unit 122 are disposed on both sides of the battery management system 11, respectively. By the arrangement, in the same battery management module, the wireless signal sent by the wireless transmitting unit 122 is blocked by the battery management system 11 and cannot be received by the wireless receiving unit 121 in the battery management module, so that the situation of incorrect addressing is further avoided.
Optionally, with continued reference to fig. 3, the battery management module 1 further includes

Specifically, when the battery management module does not receive the external battery management system address information, an external instruction may be sent to the self-encoding unit 14 in other manners, so that the self-encoding unit generates a self-encoding signal to the encoding system, and further, the encoding system is enabled to encode and form the local battery management system address information. The situation that the battery management module cannot generate the address information of the local battery management system is prevented. Illustratively, the self-encoding unit 14 may be a push-button switch and the local battery management system address information generated by the encoding system in response to the self-encoding signal may be a preset address.
Alternatively, as shown in fig. 3, the battery management device includes a first battery management module 101 and a second battery management module 102; the coding system of the first battery management module 101 is configured to obtain the address information of the local battery management system from the codes; the wireless communication system of the first battery management module 101 is configured to transmit local battery management system address information of the first battery management module; the encoding system of the second battery management module 102 is configured to obtain the local battery management system address information of the second battery management module 102 according to the local battery management system address information encoding of the first battery management module 101; the wireless communication system of the second battery management module 102 is configured to receive the local battery management system address information of the first battery management module 101 and transmit the local battery management system address information of the second battery management module 102.
Specifically, the first battery management module 101 may be understood as an addressed initial battery management module that cannot receive the external battery management system address information, and thus may control the corresponding coding system to self-encode to obtain the local battery management system address information. Then, the wireless communication system of the first battery management module sends the address information of the local battery management system to the outside. The wireless communication system of the second battery management module receives the address information of the local battery management system sent by the first battery management module. It should be noted that, for the second battery management module, the local battery management system address information of the first battery management module is external battery management system address information of the second battery management module. And then the second battery management module generates the local battery management system address information of the second battery management module according to the received external battery management system address information (namely the local battery management system address information of the first battery management module), and finally the local battery management system address information is sent to the outside by the wireless communication system of the second battery management module.
Optionally, as shown in fig. 3, the battery management device further includes a third battery module 103, and the coding system of the third battery module 103 is configured to obtain the local battery management system address information of the third battery module 103 according to the local battery management system address information code of the second battery management module 102; the wireless communication system of the third battery module 103 is configured to receive the local battery management system address information of the second battery management module 102 and transmit the local battery management system address information of the third battery module 103.
Specifically, the wireless communication system of the second battery management module sends the address information of the local battery management system to the outside. The wireless communication system of the third battery management module receives the address information of the local battery management system sent by the second battery management module. For the third battery management module, the local battery management system address information of the second battery management module is external battery management system address information of the third battery management module. And then the third battery management module generates the local battery management system address information of the third battery management module according to the received external battery management system address information (namely the local battery management system address information of the second battery management module), and finally the local battery management system address information is sent to the outside by the wireless communication system of the third battery management module.
In addition, all the battery management modules have the same structure. For the battery management module at the starting position, the external battery management system address information cannot be received. Therefore, when the battery management device is required to start addressing, for the battery management module at the initial position, the self-encoding unit 14 performs a preset operation, so that the address is set as a preset address, and the preset address is the address information of the local battery management system corresponding to the initial battery management module. And the subsequent battery management modules can all receive the external battery management system address information sent by the previous-stage battery management module. The battery management device of the embodiment can support any number of battery management modules for addressing, for example, a fourth battery management module 104 can be added, and the coding method of the fourth battery management module 104 is similar to the coding flow of the third battery module 103, which is not described herein.
With continued reference to fig. 3, the battery management device further includes a battery cluster frame 2, and the battery management module 1 is fixed to the battery cluster frame 2. Thereby preventing the battery management module 1 from moving to cause the problem of addressing errors, etc.

For example, the steps described in the present utility model may be performed in parallel, sequentially, or in a different order, so long as the desired results of the technical solution of the present utility model are achieved, and the present utility model is not limited herein.
The above embodiments do not limit the scope of the present utility model. It will be apparent to those skilled in the art that various modifications, combinations, sub-combinations and alternatives are possible, depending on design requirements and other factors.
