Description

Battery simulator with module recognition pattern and operation method of the same The present invention relates to a battery simulator having a module recognition pattern and a method of operation thereof, and more particularly to a battery simulator having a module recognition pattern that allows the size of the simulator to be reduced by vertically connecting a plurality of modules to the main board of the simulator, and does not require a separate ID for recognizing modules by electrically connecting a plurality of modules to a patterned module connection part of the main board. Generally, secondary batteries consist of a positive electrode, a negative electrode, an electrolyte, and a separator, and operate on the principle that ions move between the positive and negative electrodes to generate electrical energy. During discharge, ions move from the negative electrode to the positive electrode, and during charging, they move from the positive electrode to the negative electrode, storing and releasing energy. Commonly used rechargeable batteries include lead-acid batteries, nickel-cadmium batteries (NiCd), nickel-metal hydride batteries (Ni-MH), lithium-ion batteries (Li-ion), and lithium-ion polymer batteries (Li-ion polymer). Among these, lithium-ion batteries allow for free charging and discharging, have a very low self-discharge rate, and provide high energy density and a long cycle life. Furthermore, lithium-ion batteries can be manufactured in a compact and lightweight form factor, making them suitable for use as power sources for mobile devices. With their application expanding to electric vehicles, they are garnering widespread attention as a major energy storage medium. Meanwhile, when multiple battery cells are connected in series, they may be overcharged or undercharged compared to other battery cells, causing a difference in charge levels between the battery cells. Therefore, electric vehicles can adopt a battery management system (BMS) to manage the charge and discharge amounts of the battery cells. Since using actual batteries to evaluate such battery management systems can consume a significant amount of time and energy, battery simulators can be used to evaluate BMSs. These battery simulators mimic the electrical characteristics of batteries that output voltage and source current, and they have built-in functions for voltage and current display and monitoring. Recently, to meet the high voltage demands of electric vehicles and ESSs, multi-channel battery simulators with over 300 channels are required. Consequently, the size of the simulators is increasing, and because they have a very large volume with dimensions of W (600mm) / H (1000mm) / D (700mm) based on 96 channels, there are limitations on installation or development locations when developing high-voltage products of around 96 channels. An example of technology related to such battery simulators is disclosed in the following patent documents 1 and 2. For example, Patent Document 1 below discloses a power supply device for a battery simulator that can maximize space efficiency by minimizing the size of the transformer even as the number of voltage simulation cells increases, by including a primary coil section that is fixed at one number regardless of the increase in the number of voltage simulation cells of the battery simulator, and a secondary coil section that increases in number at the same rate proportional to the increase in the number of voltage simulation cells of the battery simulator. In addition, Patent Document 2 below discloses a battery simulation device capable of maximizing device output efficiency by minimizing the imbalance of input voltage, internal circulating current, and output terminal ripple current for the battery simulator circuit through balancing control and interleaved control.
