1.1. Electricity Rates and Time-of-Use (TOU) Pricing
Your local electricity rate is the foundation of your charging costs. Rates vary significantly depending on your location and electricity provider. Moreover, many utilities offer Time-of-Use (TOU) pricing, where electricity costs less during off-peak hours, typically overnight.
- Example: In California, electricity rates can range from $0.20/kWh to $0.40/kWh or more, depending on the time of day and provider. Charging during off-peak hours (e.g., after 9 PM) can significantly reduce your charging costs.
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 October 2024. However, this number can vary widely by state. You can find detailed information on electricity prices by state on the EIA website.
1.2. Charging Levels: Level 1, Level 2, and DC Fast Charging
Different charging levels offer varying speeds and, consequently, different costs.
- Level 1 Charging: Uses a standard 120V household outlet. It’s the slowest option, adding only 3-5 miles of range per hour. While convenient, it’s generally not practical for daily charging unless you drive very little.
- Level 2 Charging: Requires a 240V outlet and a dedicated charging station. It’s significantly faster, adding 12-80 miles of range per hour, depending on the car and charger. Level 2 charging is ideal for home use and is also commonly found at workplaces and public charging stations.
- DC Fast Charging (DCFC): The fastest charging option, using high-voltage direct current. It can add 60-200 miles of range in just 30 minutes. DCFC is primarily found at public charging stations and is best suited for long-distance travel.
- Note: DCFC is generally more expensive than Level 2 charging due to the higher power delivery and infrastructure costs.
1.3. Battery Capacity and Charging Efficiency
The size of your EV’s battery (measured in kWh) determines how much energy it needs to fully charge. Charging efficiency refers to how much of the electricity drawn from the grid actually makes it into the battery. Some energy is lost as heat during the charging process.
- Example: A Tesla Model 3 Long Range has a battery capacity of approximately 75 kWh. If you’re charging from near empty, you’ll need to supply at least 75 kWh of electricity to fully charge the battery.
- Note: Charging efficiency typically ranges from 85% to 95%. This means that for every 100 kWh you draw from the grid, 85-95 kWh will end up in your battery.
1.4. Public Charging Network Pricing Models
Public charging networks like Electrify America, ChargePoint, and EVgo employ different pricing models:
- Per-kWh Pricing: You pay for the actual amount of electricity you consume. This is the most common and transparent model.
- Per-Minute Pricing: You pay for the amount of time you’re connected to the charger. This model can be less predictable, as charging speeds can vary.
- Subscription Plans: Some networks offer monthly subscription plans that provide discounted charging rates. These plans can be cost-effective if you charge frequently at that network’s stations.
- Idle Fees: Many networks charge idle fees if you leave your car plugged in after it’s finished charging. This encourages drivers to free up chargers for others.
1.5. Location and Provider
The cost to charge an EV can also depend on where you are and which charging provider you choose. For instance, charging in urban areas or at stations located near highways might be more expensive due to higher demand and operational costs.

2.2. Estimating Your Charging Needs
Calculate how many kWh you typically need to add to your battery each day or week. This depends on your driving habits and the efficiency of your EV.
- Example: If you drive 50 miles per day and your EV gets 3 miles per kWh, you’ll need to add approximately 16.7 kWh per day (50 miles / 3 miles/kWh = 16.7 kWh).
2.3. Calculating the Cost Per Charge
Multiply your electricity rate by the number of kWh needed to charge.
- Using the off-peak rate: 16.7 kWh * $0.15/kWh = $2.51 per day.
- Using the peak rate: 16.7 kWh * $0.30/kWh = $5.01 per day.
2.4. Factoring in Charging Efficiency
Remember that some energy is lost during charging. To account for this, divide the kWh needed by your charging efficiency. Assuming 90% efficiency:
-
- 7 kWh / 0.90 = 18.56 kWh needed from the grid.
- Off-peak cost: 18.56 kWh * $0.15/kWh = $2.78 per day.
- Peak cost: 18.56 kWh * $0.30/kWh = $5.57 per day.
2.5. Annual Charging Cost Estimate
To estimate your annual charging cost, multiply your daily cost by 365 days.
- Off-peak annual cost: $2.78/day * 365 days = $1014.70 per year.
- Peak annual cost: $5.57/day * 365 days = $2033.05 per year.
