Vehicle-to-grid (V2G) concept in Power Electronics - Mini Project: Build & Apply

Understanding Vehicle-to-Grid (V2G) Concept

📖 Scenario: You are learning about how electric vehicles (EVs) can interact with the power grid to help balance electricity supply and demand.This is called Vehicle-to-Grid or V2G technology.

🎯 Goal: Build a simple step-by-step explanation of the Vehicle-to-Grid (V2G) concept using a structured data approach.You will create data representing EVs, set a threshold for battery charge, identify which vehicles can supply power back to the grid, and finalize the concept with a summary.

📋 What You'll Learn

Create a dictionary named ev_batteries with exact EV IDs and their battery charge percentages

Create a variable named charge_threshold set to 50

Use a dictionary comprehension named v2g_ready to select EVs with battery charge above charge_threshold

Add a final summary string variable named summary explaining the V2G readiness

💡 Why This Matters

🌍 Real World

Vehicle-to-Grid technology helps electric vehicles support the power grid by supplying stored energy when needed, improving energy efficiency and grid stability.

💼 Career

Understanding V2G concepts is important for careers in renewable energy, electric vehicle technology, and smart grid engineering.

1

Create EV battery charge data

Create a dictionary called ev_batteries with these exact entries: 'EV1': 80, 'EV2': 45, 'EV3': 60, 'EV4': 30, 'EV5': 90

Power Electronics

# Create the dictionary ev_batteries with EV IDs and their battery charge percentages
# Your code here

Need a hint?

Use curly braces to create a dictionary with keys as EV IDs and values as battery percentages.

2

Set the battery charge threshold

Create a variable called charge_threshold and set it to 50 to represent the minimum battery charge percentage for V2G participation.

Power Electronics

ev_batteries = {'EV1': 80, 'EV2': 45, 'EV3': 60, 'EV4': 30, 'EV5': 90}
# Create the charge_threshold variable and set it to 50
# Your code here

Need a hint?

Just assign the number 50 to the variable named charge_threshold.

3

Identify EVs ready for V2G

Use a dictionary comprehension named v2g_ready to select EVs from ev_batteries whose battery charge is greater than charge_threshold.

Power Electronics

ev_batteries = {'EV1': 80, 'EV2': 45, 'EV3': 60, 'EV4': 30, 'EV5': 90}
charge_threshold = 50
# Create v2g_ready dictionary with EVs having charge > charge_threshold
# Your code here

Need a hint?

Use a dictionary comprehension with for ev, charge in ev_batteries.items() and an if condition.

4

Add a summary of V2G readiness

Create a string variable called summary that explains: "EVs ready for Vehicle-to-Grid (V2G) are those with battery charge above 50%."

Power Electronics

ev_batteries = {'EV1': 80, 'EV2': 45, 'EV3': 60, 'EV4': 30, 'EV5': 90}
charge_threshold = 50
v2g_ready = {ev: charge for ev, charge in ev_batteries.items() if charge > charge_threshold}
# Create summary string explaining V2G readiness
# Your code here

Need a hint?

Assign the exact sentence as a string to the variable named summary.
