1.1 Electricity Prices

The cost of electricity is the most significant factor in determining your EV charging costs. Electricity prices vary widely depending on your location, time of day, and energy provider.

• Location: Electricity rates can differ significantly from state to state and even within different regions of the same state. States with abundant renewable energy sources or lower demand often have cheaper electricity.
• Time of Use (TOU) Rates: Many utility companies offer Time of Use (TOU) rates, where electricity is cheaper during off-peak hours (typically overnight) and more expensive during peak hours (usually during the day).
• Energy Provider: Different energy providers may offer different rates and plans. Comparing options from various providers can help you find the most cost-effective solution for your EV charging needs.

Example:

According to the U.S. Energy Information Administration (EIA), the average residential electricity price in the United States was about 16 cents per kilowatt-hour (kWh) in 2024. However, this average can vary significantly. For instance, states like Louisiana may have rates as low as 10 cents per kWh, while states like Hawaii can have rates exceeding 40 cents per kWh.

1.2 Battery Capacity and Efficiency

The size of your EV’s battery and its efficiency also play a crucial role in determining charging costs. Larger batteries require more electricity to charge, but they also offer a longer driving range. Efficiency refers to how well your EV converts electricity into miles driven.

• Battery Capacity: Measured in kWh, battery capacity indicates how much energy the battery can store. An EV with a 75 kWh battery will require more electricity to fully charge than one with a 40 kWh battery.
• Efficiency (Miles per kWh): This metric tells you how many miles you can drive on one kWh of electricity. A more efficient EV will travel farther on the same amount of electricity, reducing your overall charging costs.

Example:

Let’s compare two popular EVs:

• Tesla Model 3: With a battery capacity of around 75 kWh and an efficiency of about 4 miles per kWh, a full charge would require 75 kWh and provide a range of approximately 300 miles.
• Nissan LEAF: With a battery capacity of 40 kWh and an efficiency of about 3.5 miles per kWh, a full charge would require 40 kWh and provide a range of approximately 140 miles.

1.3 Charging Levels

The type of charging equipment you use also affects the cost and speed of charging. There are three main charging levels:

• Level 1 Charging: Uses a standard 120V household outlet. It’s the slowest charging method, adding about 3-5 miles of range per hour.
• Level 2 Charging: Requires a 240V outlet (like those used for appliances). It’s faster than Level 1, adding about 20-30 miles of range per hour.
• DC Fast Charging (Level 3): Uses high-voltage direct current (DC) and is the fastest charging method, adding 60-80 miles of range in about 20 minutes.

Charging Level Comparison

Charging Level	Voltage	Charging Speed	Typical Use Case
Level 1	120V	3-5 miles of range per hour	Home charging (overnight)
Level 2	240V	20-30 miles of range per hour	Home or public charging stations
DC Fast	400-800V	60-80 miles in 20 minutes	Public charging stations (travel)

Level 1 charging is usually the cheapest because it uses existing household electricity. Level 2 charging may require installing a dedicated circuit, but it’s more efficient for daily use. DC Fast Charging is the most expensive due to the high power demand and infrastructure costs.

1.4. Public vs. Home Charging

Where you charge your EV also significantly impacts the cost. Home charging is typically cheaper than using public charging stations.
