Abstract: A battery pack simulation device includes an input unit that receives voltage values, current values, temperature, and initial impedance values, an output value generation unit that generates an output value based on the input voltage value, current value, temperature, and initial impedance value, an output unit that transmits the generated output value to the battery management unit, and a monitoring unit that monitors the operation of the battery management unit.

Abstract: 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.

Abstract: A battery pack that is mounted to a laptop computer, wherein two or more battery cells that can be charged and discharged are housed in a pack case; the battery cells are cylindrical battery cells having a circular vertical cross-section; the pack case is configured with a lower case in which battery cells are received and an upper case that is coupled to the lower case in order to close and seal the battery cells; in the upper case, a thickness of an upper contact point portion that contacts an upper end external circumferential surface of the battery cells is 70% or less of that of the remaining portions of the upper case, and a first sheet is attached to an outer surface of the upper case corresponding to the upper contact point portion; and in the lower case, a thickness of a lower contact point portion that contacts a lower end external circumferential surface of the battery cells is 70% or less of that of the remaining portions of the lower case, and a second sheet is attached to an outer surface of the
