추천 예제
HV 배터리 충전/방전
이 예제에서는 하이브리드 전기차에 사용되는 것과 같은 고전압 배터리를 보여줍니다. 이 모델은 동적 구동 사이클에서 비롯되는 실제 DC 링크 전류 프로파일을 사용합니다. 총 시뮬레이션 시간은 3,600초입니다.
Battery Pack Cell Balancing
Implement a passive cell balancing for a Lithium-ion battery pack. Cell-to-cell differences in the module create imbalance in cell state of charge and hence voltages. In this example, the balancing algorithm starts when the battery pack is idle and the difference in the cell state of charge is above a certain predefined value.
Battery Pack Thermal Management
Model an automotive battery pack for thermal management tasks. The battery pack consists of several battery modules, which are combinations of cells in series and parallel. Each battery cell is modeled using the Battery (Table-Based) Simscape™ Electrical™ block. In this example, the initial temperature and the state of charge are the same for all cells. Four battery modules, three similar and one differing from the other three, are connected in series to simulate a battery pack. The results in this example assume an initial ambient temperature equal to 25 degree Celsius. The Coolant Controls subsystem defines the logic used to determine the battery pack coolant flow rate.
Battery Pack DC Fast Charging
Model an automotive battery pack for DC fast charging tasks. The battery pack consists of several battery modules, which are combinations of cells in series and parallel. Each battery cell is modeled using the Battery (Table-Based) Simscape Electrical block. In this example, the initial temperature and the state of charge are the same for all cells. The cell capacity varies according to the manufacturing tolerances or uncertainties. Three battery modules, two similar and one differing from the other two, are connected in series to simulate a battery pack. The results in this example assume an initial ambient temperature equal to zero degree Celsius. The Controls subsystem defines the logic to determine the battery pack charging time and current.
Battery Pack Short Circuit
Model a short-circuit in a lithium-ion battery module. The battery module consists of 30 cells with a string of three parallel cells connected in a series of ten strings. Each battery cell is modeled using the Battery (Table-Based) Simscape Electrical block. In this example, the initial temperature and the state of charge are the same for all cells. There is no coolant flow modeled in this example. The battery module is shorted with a 0.1mOhm resistor. There is an inrush current followed by cell quick discharge and heating up. Once the cell reaches the trigger temperature for thermal runaway and cell venting, the electrical circuit is disconnected to stop the electrical simulation.
영구 자석 동기 발전기 배터리 충전
이 예제에서는 배터리를 충전하기 위해 영구 자석 동기 발전기(PMSG)를 사용하는 방법을 보여줍니다. 이상적 각속도 소스는 회전자 속도를 일정하게 유지하는 데 사용됩니다. Control 서브시스템은 자속 기준 제어를 사용하여 PMSG의 토크를 조정합니다. 토크 기준은 dc 링크 전압의 함수로 얻어집니다. 초기 배터리 충전 상태는 25%입니다. Scopes 서브시스템은 시뮬레이션 결과를 확인할 수 있는 스코프를 포함합니다.
슈퍼커패시터 충전 및 방전 동작
이 예제에서는 충전된 다음 방전될 때 Supercapacitor 블록에서 출력하는 전압을 보여줍니다. 슈퍼커패시터를 충전하기 위해 100mA의 전류가 100초 동안 슈퍼커패시터에 입력됩니다. 그런 다음, 슈퍼커패시터는 1분 동안 휴지 상태에 있습니다. 다음 1시간 동안, 슈퍼커패시터를 방전하기 위해 50초마다 1초간 50mA의 부하가 걸립니다. 그런 다음, 슈퍼커패시터는 시뮬레이션이 끝날 때까지 휴지 상태에 있습니다. 스코프에 슈퍼커패시터 충전/방전 전류 및 전압이 표시됩니다.
Ultracapacitor with Converter
Use a DC-DC converter to maintain a constant load voltage when drawing power from an ultracapacitor. The converter supplies power to the load and the capacitor voltage drops. The protection circuit disconnects the load when the capacitor voltage drops below a threshold value of 4V. At 10 seconds, the generator turns on, supplies power to the load and charges back the capacitor.
스마트폰 배터리 충전
이 예제에서는 스마트폰의 전형적인 배터리에 정전류(CC) 충전과 정전압(CV) 충전을 설정하는 방법을 보여줍니다. 정전류가 배터리 충전을 시작합니다. 배터리 전압이 특정 값에 도달하면 정전압 충전 과정이 시작됩니다.
Battery Pack Fault Protection
Model fault and fault protection using a fuse in an automotive battery pack. The battery pack consists of several battery modules, which are combinations of cells in series and parallel. Each battery cell is modeled using the Battery (Table-Based) Simscape Electrical block. In this example, the initial temperature and the state of charge are the same for all cells. Four battery modules, three similar and one differing from the other three, are connected in series to simulate a battery pack. The results in this example assume an initial ambient temperature equal to 25 degree Celsius. The Control subsystem defines the logic used to determine the battery pack coolant flow rate. A fuse is placed inline to battery pack as a measure of fault protection.
Peak Shaving with Battery Energy Storage System
Model a battery energy storage system (BESS) controller and a battery management system (BMS) with all the necessary functions for the peak shaving. The peak shaving and BESS operation follow the IEEE Std 1547-2018 and IEEE 2030.2.1-2019 standards.
