Therefore, in order to change the identification code of the battery pack later, it is necessary to use a corresponding recording device to change the identification code stored in the non-volatile memory. In this way, it will cause inconvenience to the operation of changing the identification code.

The microcontroller 44 generates a corresponding identification code according to the encoding configuration of the encoder 30 , and outputs a status signal according to the identification code and the state of the battery cell pack 20 , which is converted into a corresponding bus signal through the communication interface 46 and then output. In addition, the battery pack monitoring unit 40 can further control the switch element 262 to turn off, so that the battery cell pack 20 stops outputting power to the positive terminal 12 and the negative terminal 14 , so as to cut off the power output from the battery pack 100 .

藉此，电池包100所输出的状态信号中包含了对应编码器30的编码组态的识别码及电池芯组20的状态。人员可以手动从编码器30的操作部34改变编码组态，进而改变电池包100的识别码，使本实施例的电池包100成为通用型电池包，亦即，在生产电池包100时无需针对电池包100设定唯一的识别码。Therefore, the status signal output by the battery pack 100 includes the identification code corresponding to the coding configuration of the encoder 30 and the status of the battery cell pack 20 . Personnel can manually change the coding configuration from the operation part 34 of the encoder 30, and then change the identification code of the battery pack 100, so that the battery pack 100 of this embodiment becomes a general-purpose battery pack, that is, when producing the battery pack 100, there is no need to target the battery pack 100. The battery pack 100 is set with a unique identification code.

图3所示为使用多个本实施例的电池包100的电力系统1，电力系统1的电池管理装置200通过总线连接到每一个电池包100的套接端子16，藉以与电池包监控单元40通信。用户在组装电力系统1时，可以直接于各个电池包100的编码器30设定编码组态，且通过位在壳体10外的操作部可以达到方便用户调整编码组态的功效。将每个电池包100的编码组态设成不同(即图3中的1～16)之后，即可让每个电池包100将状态信号传送至电池管理装置200，电池管理装置200解析所收到的状态信号后，即可判断状态信号是由哪个电池包100发送。FIG. 3 shows a power system 1 using a plurality of battery packs 100 of the present embodiment. The battery management device 200 of the power system 1 is connected to the socket terminal 16 of each battery pack 100 through a bus, so as to communicate with the battery pack monitoring unit 40 communication. When assembling the power system 1 , the user can directly set the coding configuration on the encoder 30 of each battery pack 100 , and the user can easily adjust the coding configuration through the operation part located outside the casing 10 . After setting the coding configuration of each battery pack 100 to be different (ie, 1 to 16 in FIG. 3 ), each battery pack 100 can transmit a status signal to the battery management device 200 , and the battery management device 200 can analyze the received After receiving the status signal, it can be determined which battery pack 100 the status signal is sent from.

更值得一提的是，当有任一电池包100需替换时，只要将原本的电池包100取下，再将新的电池包100换上，同时将新的电池包100的编码器30的编码组态设定成与原本电池包的编码组态相同即可，有效改善常用的电池包需要重新刻录识别码的缺失。What is more worth mentioning is that when any battery pack 100 needs to be replaced, just remove the original battery pack 100 and replace it with a new battery pack 100. The coding configuration can be set to be the same as the coding configuration of the original battery pack, which effectively improves the lack of identification codes that need to be re-recorded for commonly used battery packs.

以上所述仅为本发明优选可行实施例而已，举凡应用本发明说明书及权利要求书所为的等效变化，理应包含在本发明的专利范围内。The above descriptions are only preferred and feasible embodiments of the present invention, and all equivalent changes made by applying the description and claims of the present invention should be included in the patent scope of the present invention.
