SUMMARY OF THE INVENTION The embodiments disclosed herein relate to a battery management device and method of operation. [Background technology]

[0002] In recent years, research and development into secondary batteries has been actively pursued. Here, secondary batteries are batteries that can be charged and discharged, and include both conventional Ni / Cd batteries, Ni / MH batteries, and more recent lithium-ion batteries. Among secondary batteries, lithium-ion batteries have the advantage of having a much higher energy density than conventional Ni / Cd batteries, Ni / MH batteries, and other batteries. Furthermore, because lithium-ion batteries can be manufactured to be compact and lightweight, they are used as power sources for mobile devices. In recent years, their range of use has expanded to include power sources for electric vehicles, and they are attracting attention as a next-generation energy storage medium.

[0003] Furthermore, the secondary battery can generally be used as a battery pack including a battery module in which a plurality of battery cells are connected in series and / or parallel, and can also be used as a battery rack including a plurality of battery modules and a rack frame for accommodating such battery modules.

[0004] Such batteries can be managed and controlled in status and operation by a battery management system (BMS), which can be included with the batteries in a device, or can manage and control the batteries remotely from the device containing the batteries.

[0005] In order to properly manage and control batteries, it is necessary to match the identification information of a specific battery with the identification information of a battery management system that manages and controls the specific battery. For this reason, for example, in a configuration in which battery management systems are included in batteries, it is important to know which battery each battery management system is included in.
