배터리 팩 모델링
Simscape™ Battery™에는 Simscape 배터리 모델의 생성을 자동화하는 MATLAB® 객체와 메서드가 포함되어 있습니다. 이러한 MATLAB 객체를 사용하여 고유한 배터리 설계 사양을 정의하고, 3차원 공간에 배터리를 시각화하고, 시뮬레이션 중에 모델링 분해능을 사용자 지정하고, 사용자 지정하여 생성한 배터리 블록이 포함된 Simulink® 라이브러리를 생성할 수 있습니다. 이러한 배터리 블록을 사용하면 가상 배터리를 설계하고 검증하는 데 도움을 줄 수 있으며, Simulink를 사용하여 배터리 제어 알고리즘을 개발하고, 설계 민감도를 탐색하고, 열 관리 전략을 설계하는 데에도 도움이 됩니다.
Simscape Battery의 BMS(Battery Management System) 라이브러리에 있는 블록을 사용해 사용자 지정 배터리 블록을 시뮬레이션하여 배터리 제어 전략을 개발하고 테스트할 수 있습니다. 또한 Thermal Management System 라이브러리에 있는 블록을 사용해 Simulink에서 사용자 지정 배터리 모델을 열적으로 결합할 수 있습니다. 또는 사용자 지정 배터리 제어 및 냉각 시스템 블록을 자체적으로 정의할 수도 있습니다.

Build Battery Model from Custom Cell Component
Create and build a Simscape™ model of a battery parallel assembly from a custom cell component. To build a battery system, you can either use the cell blocks in the Simscape Battery™ library or use a custom cell component. This approach allows you to use a custom cell component tailored to your requirements to build a battery system.
Design Battery Module for Automotive Requirements
Design a battery module and a cooling plate from battery cell test data. Modular battery units are a good solution to decrease the cost of automotive battery packs. Battery modules can help meet requirements of different customers in similar industry domains. The battery cells are typically parameterized using pulse discharge and charge data. This example uses the hybrid pulse power characterization (HPPC) test [1] to estimate the battery ohmic resistance and other dynamic resistance values.
Inject Faults in Battery Models
Inject faults in battery models during simulations using Simscape™ Battery™ and Simulink® software. First, you explore the effect of disconnecting a battery cell from the other cells of a parallel assembly inside a battery module. A cell disconnection typically happens due to a weld failure or a failure in the cell current interruption device. Then, you add an internal short-circuit fault to a cell of a parallel assembly inside a battery module. The fault triggers a set of exothermic reactions, known as a thermal runaway. You activate both faults during the simulation by using a timed trigger at a simulation time of 30 seconds.
Apply Temperature-Dependent Cell Parameter Variations to Battery Module
Apply temperature-dependent parameter variations to the individual cell models in a battery module generated using Simscape™ Battery™ objects and functions. Modeling temperature-dependent parameter variation is essential for achieving accurate performance predictions, optimizing efficiency, and designing and developing advanced battery systems.
