- Patent Document 1 discloses an invention that can improve the traffic load of a CAN bus by improving the stability of data reception and improving the communication speed by changing the data frame structure for CAN (Controller Area Network) communication to increase the amount of data.
- CAN Controller Area Network
- Patent Document 1 only discloses a configuration in which the receiving side of this data changes the reception mode to high-speed mode or normal mode depending on whether the data length exceeds 8 bytes. Since Patent Document 1 improves the traffic load only by changing the reception mode, there is a problem in that it is difficult to apply to devices such as electric vehicles in which various information about battery cells must be provided in real time. That is, according to Patent Document 1, since the transmitting side must transmit a single piece of information about the battery cell, there is a problem in that a considerable amount of time may be required for data transmission.

Therefore, since all battery information for a plurality of battery cells must be received and only the desired battery information must be extracted, there is a problem that it may take a considerable amount of time to obtain the desired battery information.
