Description

Method for transmitting BMIC data and apparatus therefor The present disclosure relates to a technology for transmitting data from a BMIC, and more specifically, to a BMIC data transmission method and apparatus for minimizing the amount of communication of a BMIC based on the resolution of data monitored by a BMIC (Battery Monitoring IC). Batteries are used in various fields, including portable electronic devices such as smartphones, laptop computers, and tablet PCs, as well as electric scooters, electric vehicles, and energy storage capacitors. These batteries are equipped with a Battery Management System (BMS), which is an electronic system designed to monitor the battery's condition and manage it. Meanwhile, when the Battery Management System (BMS) performs an Analog to Digital Converter (ADC) on voltage, current, temperature, etc. through the GPIO pins of the Battery Monitoring IC (BMIC) or Micro Control Unit (MCU) configured within it, it applies an RC filter to reduce frequency noise. Figure 1 shows an example diagram for explaining a conventional BMIC data transmission method. FIG. 2 shows an operation flowchart of a BMIC data transmission method according to one embodiment of the present disclosure. FIG. 3 is an exemplary diagram illustrating a BMIC data transmission method according to one embodiment of the present disclosure. FIG. 4 shows the configuration of a BMIC data transmission device according to another embodiment of the present disclosure. FIG. 5 is a block diagram of a computing system for executing a BMIC data transmission method according to one embodiment of the present disclosure. Hereinafter, embodiments of the present disclosure are described in detail with reference to the attached drawings so that those skilled in the art can easily implement them. However, the present disclosure may be embodied in various different forms and is not limited to the embodiments described herein. In describing the embodiments of the present disclosure, if it is determined that a detailed description of known configurations or functions could obscure the essence of the present disclosure, such detailed description is omitted. Additionally, parts of the drawings unrelated to the description of the present disclosure have been omitted, and similar parts are denoted by similar reference numerals. In the present disclosure, when a component is described as being "connected," "combined," or "joined" with another component, this may include not only a direct connection but also an indirect connection in which another component exists in between. Furthermore, when a component is described as "comprising" or "having" another component, this means that, unless specifically stated otherwise, it does not exclude the other component but may include an additional component. In the present disclosure, terms such as first, second, etc. are used solely for the purpose of distinguishing one component from another component and do not limit the order or importance of the components unless specifically stated otherwise. Accordingly, within the scope of the present disclosure, a first component in one embodiment may be referred to as a second component in another embodiment, and likewise, a second component in one embodiment may be referred to as a first component in another embodiment. In the present disclosure, distinct components are intended merely to clearly explain their respective features and do not imply that the components are separate. That is, multiple components may be integrated to form a single hardware or software unit, or a single component may be distributed to form multiple hardware or software units. Accordingly, such integrated or distributed embodiments are included within the scope of the present disclosure, even if not otherwise mentioned. In the present disclosure, the components described in various embodiments do not necessarily mean essential components, and some may be optional components. Accordingly, embodiments consisting of a subset of the components described in one embodiment are also included within the scope of the present disclosure.
