In the embodiment of the invention, the state data packet comprises the battery combination type and the capacity. The battery combination type represents a battery type which is matched with an adaptive battery holder type, and the battery combination type can be represented by 2 bits or 4 bits, for example, when the battery combination type is 0001, the battery holder matched with the current battery combination type is a 3C battery holder, when the battery combination type is 0002, the battery holder matched with the current battery combination type is a 4C battery holder, and when the battery combination type is 0003, the battery holder matched with the current battery combination type is a 4F battery holder. In the embodiment of the invention, the battery capacity can be represented by 2 bytes, and the battery capacity range is represented as follows: 0-6535mAh. The 3C battery clamp is characterized in that the battery pack of the corresponding power supply device matched with the 3C battery clamp is formed by connecting 3 lithium cobalt oxide batteries in series, the voltage of a single battery is 3.7V, and the rated voltage of the combined battery pack is 11.1V. The 4C battery clamp means that the battery pack of the corresponding power supply device matched with the 4C battery clamp is formed by connecting 4 lithium cobalt oxide batteries in series, the voltage of a single battery is 3.7V, and the rated voltage of the combined battery pack is 14.8V. The 4F battery clamp is that the battery pack of the corresponding power supply device matched with the battery clamp is formed by connecting 4 lithium iron phosphate batteries in series, the voltage of a single battery is 3.2V, and the rated voltage of the combined battery pack is 12.8V.
Preferably, the status data packet further includes a battery status, and the battery status includes a voltage of a single battery and a battery temperature. The voltage of a single battery can be represented by 5 bits, the representation range is 0-15V, the voltage can be specifically set according to requirements, and the battery temperature can also be similarly represented. Meanwhile, the voltage and the temperature of the single battery can also be simply expressed by 1bit, namely 1 or 0, for example, when the voltage bit of the single battery is 1, the voltage is under-voltage, and when the voltage bit of the single battery is 0, the voltage is normal; when the battery temperature level is 1, the battery temperature level indicates over-temperature, and 0 indicates normal temperature.
Preferably, in an embodiment of the present invention, the status packet structure includes a first start bit, one or more first data bits, and a first end bit. The first start bit is used for synchronization, the first data bit is a data bit indicating the state of the power supply device, and is used for indicating the state of the power supply device, and specifically, one or more data bits are used for indicating the type, capacity and battery state of the battery combination.

Preferably, in the embodiment of the present invention, the format of the status data packet is shown in table 1.
TABLE 1 status packet format
| First start position | First data bit | First end position |
In the embodiment of the invention, because the state data packet is added into the battery combination type and the battery state information which are matched with the corresponding battery type of the power supply device in the communication, and the battery clamp is switched to the working mode matched with the battery combination type information after receiving the battery combination type information sent by the power supply device, the battery clamp can be universally used for different types of power supply devices.
