how to model an electric vehicle and its charge discharge

Want to model electric vehicle (30kW battery capacity) and charge by 1C/2C/3C rates with 3kW/5kW/10kW charger and consumption 150Wh/km.

How can I model it in simulink to charge it from transformer and after discharge in certain time period then again charge. First need to model one EV then I will go throgh multiple EVs with different battery capacity and their charge discharge caracteristics.

Please also provide any reference for study for simulation

Thanks

[MUKESH KUMAR]

Can I write the script for it in .m file rather than simulink model design of full EV, how to write code for this ??

Hi Mukesh,

Please take a look at this content that was presented in a MOOC.

Dont need to go in detailed modeling, i need only consumption of EVs in kW in a regular time interval like 15 0r 30 min with a 30kW battery capacity ,charging with charger of 3kW or 5kW ? then modeling large numbers of EVs

Hi Mukesh,

From your question, it seems like you are focusing on Charger performance and interaction with Battery, but care less about detailed model of Electric Vehicle.

If that is true, examples in Simscape Electrical can help you create a system level model. Here are some examples that you can refer to.

Not going in details with EV modeling and charger, just taken an EV and its charging behaviour with any charger type then want to model similar more number of EVs in 1000 times to see the impact on Grid.

i want to study EV charger (LEVEL 2) model with improved power quality.

can anyone provide simulation reference or anyother reference?

[Hakan Kaya]

Hi, Did you find anything about EV charger(LEVEL 2) model? I try to find this simulation in everywhere but ı couldn't find anything. :(

i want deterministic model to develop a charging/discharging strategy for EVs located in a parking lot integrated with a photovoltaic system to ensure optimal operation in the day ahead. The time-of-use (ToU) price is used to minimize the day-ahead operation cost of energy trading to the charging station.

The modeling of electric vehicles and their charge-discharge behavior is crucial for understanding their performance and optimizing their operation. This process involves accurately representing the vehicle's battery, powertrain, and control systems within a computational framework. By considering factors such as battery capacity, efficiency, and power demand, a comprehensive model can simulate various driving conditions and predict the vehicle's range, energy consumption, and charging requirements. This enables engineers and researchers to assess the impact of different factors on electric vehicle performance and develop strategies for efficient charging and discharging. Accurate modeling plays a vital role in advancing electric vehicle technology and promoting their widespread adoption. You must also check out Dormitxelectric.com it has some great insights too.

I'm coming back to this older thread because it still gets a lot of views. Since the question was originally asked, we've created some new shipping examples that demonstrate the EV / EVSE communication.

I need help

I am working on the sizing and energy management system with vehicle to grid so i did some coding for EMS and sizing and used PSO but still not finished yet i need to put many condition for EV for example

my working during one yeas (8760 h)

1. i need used 1000 cars

2. need check SOC for each car

3. need check the time for departure and travel and how long will take time to charge or discharge

4. need check the plug in

5. availability cars

6. price for buy and sell

for for sure not all will be charge or discharge will be depend or conditions that will be put

So i need your help to do this modeling during (8760 h)

There are lots of ways to run your analysis, depending on what kind of detail you want to include. For one, you can use a Monte Carlo study to look at a statistical distribution of responses based on changes to the parameters. For example, check out this article on doing something like that. You can vary the R, C parameters in the battery model to show the impact of different charge / discharge rates.
