Simulation of DC Fast Charging Station Connected With the Battery Pack of an Electric Vehicle

This example models a DC fast charging station connected with the battery pack of an Electric Vehicle (EV). The main components of the example are: Grid: Model the AC supply voltage as a three-phase constant voltage source. DC Fast Charging Station: Model the power electronic circuits to convert the AC supply voltage from the grid to the DC voltage level that the EV battery pack requires. EV battery pack : Model the battery pack as series of battery cells. Filter & AC Measurements to filter the harmonics in the line current and measure the three-phase supply voltage and line current. Unity Power Factor (UPF) Front End Converter (FEC) to control output DC voltage at 800 V. The converter circuit is modeled with three levels of fidelity: Average Inverter Fidelity Two Level Inverter Fidelity Three Level Inverter Fidelity Isolated DC-DC converter supply constant charging current to the EV battery. These are the main components of the isolated DC-DC Converter: 1) Inverter, 2) HF Isolation Transformer, 3) Diode-Bridge Rectifier The EV Battery Pack models the battery cells connected in series and the sensors to measure the battery terminal voltage and output current. The plot below shows the DC bus voltage and current, battery terminal voltage, and charging current.

Modeling and simulation of Vehicle Engine Braking System Using Matlab Si...

What is engine braking?
Engine braking is basically the process of slowing the car down by releasing the accelerator and shifting down through gears, rather than using the footbrake.

Why Should we use it?
Using the footbrake is the most common way to reduce your speed, both in an emergency and in normal conditions.
Depending on how hard you press the brake pedal, you control the speed at which you slow down, when you stop, and when you start again.
But using the footbrake isn’t the only way to slow down. Though less commonly used, engine braking is a great way to improve your vehicle’s efficiency and help your brakes last longer.

Benefits of Engine Braking
It reduces wear and tear on your brakes.
The brake system relies on friction to slow down your vehicle.
Engine braking is especially helpful on long descents on mountains or hills.
Riding the brakes down a long slope can cause them to overheat, which decreases braking ability and damages the braking system.

Modeling and Simulation of CAN based Model with Anti-lock Braking Sy...

This example shows how Stochastic Network Traffic causes timing Latency and Uncertainty in an anti-lock braking system (ABS) that uses Control Area Network (CAN) communications. This example shows an anti-lock braking system using CAN communications and highlights the negative effect that increased network utilization can produce on latency and response times. The model is representative of a real-world heavily-loaded network and also illustrates a domain-specific model of a distributed system. This example shows an anti-lock braking system using CAN communications and highlights the negative effect that increased network utilization can produce on latency and response times.

Simulation and Analysis of Solar PV System under Shading Condition using...

• To study the effects of shading and PV cell junction temperature in a large interconnected solar plant
• 
  
• To implement shading effects in a solar photovoltaics (PV) plant
• 
  
• To improve the maximum power and to protect the solar panel from overheating, the Solar Plant block comprises bypass and blocking diodes. 

This example shows how to implement shading effects in a solar photovoltaics (PV) plant or module.

To study the effects of shading and PV cell junction temperature in a large interconnected solar plant or a single PV module. There are a number of different approaches that can be applied in PV system design to reduce shading losses.

These include the use of Different Stringing Arrangements, Bypass Diodes, and Module-level Power Electronics (MLPEs). A blocking diode allows the flow of current from a solar panel to the battery but prevents/blocks the flow of current from battery to solar panel thereby preventing the battery from discharging. Bypass diodes are used in PV modules to prevent the application of high reverse voltage across the cells in the event of shading.
