The upper computer 1 is also used for counting the number N of the received second response messages after waiting for 5 seconds, acquiring the preset ID of the slave controller 2 with the position N, and then sending the preset ID to the slave controller 2 to be configured; the slave controller 2 to be configured is further configured to update its internal packet ID to a preset ID.
Fig. 2 is a flowchart of a configuration method of a slave controller of the battery management system according to the present embodiment, where the configuration method includes the following steps:
step 101, the upper computer 1 broadcasts and sends a first command to all the slave controllers 2 through the CAN bus;

Then, in the next step 105, the slave controller 2 corresponding to the single battery 3 is selected as the slave controller 2 to be configured, because the random number corresponding to the single battery is the smallest. In step 106, the upper computer 1 sends a second command message by using the message ID value 0x02 as a message data field, only the slave controller 2 corresponding to the single battery 3 responds to the message, and the received second command message is ignored by the other three slave controllers 2 because the message IDs analyzed to be inconsistent in the data field. The slave controller 2 corresponding to the single battery 3 receives the second command message and then sends a second response message to the upper computer 1, and simultaneously drives the OUT interface to output a high level, so that the slave controller 2 corresponding to the single battery 2 detects that the IN interface has a rising edge trigger signal, so that the slave controller 2 corresponding to the single battery 2 also sends the second response message to the upper computer 1, and simultaneously drives the OUT interface to output a high level, so that the slave controller 2 corresponding to the single battery 1 detects that the IN interface has a rising edge trigger signal, and the slave controller 2 corresponding to the single battery 1 receives the trigger signal and then sends the second response message to the upper computer 1, and simultaneously drives the OUT interface to output a high level, but because the slave controller 2 corresponding to the single battery 1 is the last stage, no slave controller of the next stage continues to respond to the trigger action. From this, it can be known that the upper computer 1 has received three second response messages altogether, N in step 108 is 3, that is, the position code of the battery cell 3 is 3, the preset ID of the battery is stored in the upper computer 1 in advance, the upper computer 1 can acquire the preset ID corresponding to the battery cell 3 only according to the serial number 3, the upper computer 1 sends the preset ID to the slave controller 2 corresponding to the battery cell 3, the slave controller 2 updates the message ID therein by using the preset ID, and thus automatic configuration of the message ID corresponding to the battery cell 3 and corresponding to the slave controller 2 is completed.
The automatic configuration of the message IDs of the single batteries 2, 4 and 1 can be sequentially completed in the same manner subsequently, thereby realizing the automatic configuration of the message IDs of all the slave controllers 2.
