[0023] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0024] The battery pack information entry method described in this invention is applicable to intelligent devices such as power tools / electric equipment. As long as the aforementioned devices / tools can adopt the substantive content of the technical solutions disclosed below, they will fall within the protection scope of this invention.

[0025] Due to the rapid increase in the variety of battery packs, using different identification resistors or different software programs to distinguish battery packs can lead to problems such as ineffective identification resistor differentiation or inconsistent software files. To address these shortcomings, this invention aims to provide a method and intelligent device for inputting battery pack information. This method allows for the intuitive input of production and charge / discharge information during battery pack manufacturing. The input method is simple and can handle a large amount of information. Furthermore, this invention includes a verification function, enabling simple and direct verification of the accuracy of the stored battery pack information, ensuring the correctness of the input.

[0026] Please see Figure 4The present invention addresses the problems of existing technologies by employing the following technical solution: an intelligent device comprising a human-computer interaction module and an information conversion module. The intelligent device is used to input information into a battery pack; the human-computer interaction module is used to set the input information; the information conversion module is used to convert the input information into configuration information that meets the communication requirements of the battery pack, the configuration information including high and low level information. The input information includes battery pack production information and battery pack charging and discharging information. The battery pack production information includes production time, production location, production line identification, and production quantity. The battery pack charging and discharging information includes the number of battery cells, battery cell series and parallel arrangement information, battery cell performance, battery cell brand, maximum charging current per cell, and maximum discharging current per cell. The battery cell performance can include positive and negative electrode parameters, electrolyte composition, energy density, cycle life, conversion efficiency, etc.

[0027] The human-machine interaction module is a module with an operation display interface. The operator sets the input information of the battery pack on the human-machine interaction module. The information conversion module includes a data conversion serial port. The information conversion module converts the input information into configuration information that meets the communication requirements of the battery pack and sends it to the battery pack. The battery pack reads the configuration information and stores the configuration information in its memory.

[0028] The human-machine interaction module is equipped with multiple information windows, including a production information window and a charging and discharging information window. Operators can select an information window on the interface of the human-machine interaction module and fill in the relevant information according to the battery pack to be entered, thus setting the information of the battery pack in a simple and intuitive way.

[0029] The information conversion module stores various types of information in different formats. By converting these formats, the information can meet the communication requirements of the battery pack, thereby enabling the configuration of the battery pack.

[0030] The smart device obtains the communication requirements of the battery pack's communication protocol through interaction with the battery pack, and then feeds back the communication requirements to the information conversion module so that the module can convert the entered information into information that the battery pack can recognize according to the communication requirements.

[0031] The communication requirements include: transmitting configuration information using high and low level signals. In an optional embodiment, the communication requirements may further include: using a handshake protocol to transmit configuration information, wherein the specific settings of the handshake protocol are common in the art and will not be described in detail here.

[0032] The intelligent device can be used to send read commands to the battery pack and can also receive configuration information sent by the battery pack to perform verification steps. The verification steps include an automatic comparison verification process and a manual comparison verification process. The automatic comparison verification process includes the intelligent device automatically comparing the configuration information with the entered information to verify whether the configuration information entered into the battery pack is correct. The manual comparison verification process includes the intelligent device displaying the received configuration information on the human-computer interaction module, and the operator comparing and verifying whether the configuration information entered into the battery pack is consistent with the battery pack information.

[0033] When automatic comparison verification is used, no operator intervention is required; the consistency of information can be automatically identified and confirmed, improving the system's automation level. When manual comparison verification is used, the interaction between the system and the operator can be increased. The operator can set the fault tolerance rate through the human-computer interaction module. When the consistency level reaches a certain level, such as 95%, it is considered consistent, improving the controllability of the fault tolerance rate. The fault tolerance rate can be set according to the actual situation; the above scheme enables personalized verification settings.

[0034] Generally, after the battery pack configuration information is entered, consistency is confirmed through automatic comparison verification. Manual comparison verification is mainly used for product spot checks or quality inspection processes. Thus, through unified automatic verification and manual spot checks, the accuracy of configuration information is further improved.

[0035] Compared with existing technologies, the present invention provides an intelligent device through which operators can intuitively set and input battery pack production information and charging / discharging information into the battery pack. This effectively avoids the problem of easy errors in information input and allows for the input of a large amount of information, which can meet the needs of the rapidly growing number of battery pack types. At the same time, the intelligent device can read the configuration information stored in the battery pack to verify whether the input is correct and ensure that the input information is consistent with the battery pack.

[0037] The human-machine interaction module is equipped with multiple information windows, including a production information window and a charging and discharging information window. Operators can select an information window on the interface of the human-machine interaction module and fill in the relevant information according to the battery pack to be entered, thus setting the information of the battery pack in a simple and intuitive way.

[0038] The information conversion module internally stores various information formats and performs format conversions to meet the communication requirements of the battery pack, thereby enabling battery pack configuration. The smart device interacts with the battery pack to obtain its communication protocol requirements and then feeds these requirements back to the information conversion module, which converts the entered information into information that the battery pack can recognize.

[0039] The communication requirements include: transmitting configuration information using high and low level signals. In an optional embodiment, the communication requirements may further include: using a handshake protocol to transmit configuration information, wherein the specific settings of the handshake protocol are common in the art and will not be described in detail here.

[0043] When automatic comparison verification is used, no operator intervention is required; the consistency of information can be automatically identified and confirmed, improving the system's automation level. When manual comparison verification is used, the interaction between the system and the operator can be increased. The operator can set the fault tolerance rate through the human-computer interaction module. When the consistency level reaches a certain level, such as 95%, it is considered consistent, improving the controllability of fault tolerance. The above scheme can realize personalized verification settings.

[0044] Generally, after the battery pack configuration information is entered, consistency is confirmed through automatic comparison verification.

Interact with smart devices through these modules / interfaces to obtain the battery pack's configuration information.

[0048] For non-communicable battery packs, a separate read / write port is designed on the battery pack. This read / write port can communicate with the smart device to input battery pack information according to the information input method. A dedicated device is connected to the designated read / write port; the dedicated device can interact with the smart device to obtain the battery pack's configuration information.

[0049] Compared with existing technologies, the present invention provides a method for entering battery pack information, which intuitively enters battery pack production information and charge / discharge information during battery pack production.
