METHOD FOR UPDATING SOFTWARE BY CONFIRMING HARDWARE VERSION INFORMATION

The present invention is to identify a hardware version capable of performing a software update and does not store the version information in the hardware in the code, but inputs the version information to the microcontroller through the hardware version identification unit that stores the BMS hardware version information. Also, in order to compensate for the low channel utilization of the microcontroller when one microcontroller is used for software update, it is a device and method for operating in both the application mode and the boot mode.
