Is it Cheaper to Charge an EV at Home or at a Charging Station?

The Great EV Charging Debate

With the increase in electric vehicles, the question of where I should charge my car has become a common inquiry—at home or a public charging station. The answer often depends on your specific needs, driving habits, and local infrastructure. Let's weigh the pros and cons of both options.

Charging at Home: The Comfort and Convenience

• Cost-effective: In most cases, charging at home is the most economical option. Home electricity rates are generally lower than commercial rates at public charging stations. The average Colorado household pays approximately 14 cents per kilowatt-hour (kWh) for electricity. This means charging a large battery at home could cost around $15, compared to the average cost of $30 at a supercharger. However, the exact cost will depend on the battery's size and your specific electricity rate.
• Convenience: Waking up to a fully charged car is a perk. Home charging offers unmatched convenience, especially if you have a dedicated charging station installed.
• Time-efficient: While it may take longer to fully charge your EV at home, you can do it overnight while you sleep, ensuring your car is ready for your next adventure.

Public Charging Stations: Flexibility and On-the-Go Power

• Flexibility: Public charging stations provide flexibility, especially for long trips or when you're out and about. You don’t have to worry about if you’ll make it back home before you run out of juice.
• Faster charging: Many public charging stations offer faster charging speeds, which can be beneficial for long-distance travel or when you need a quick charge.
• Additional features: Some public charging stations offer amenities like Wi-Fi, restrooms, and food services, making your charging experience more enjoyable.

Factors to Consider

• Local infrastructure: The availability and speed of public charging stations in your area will significantly impact your decision. If there are few or no public stations nearby, or if sitting, waiting for your car to charge sounds dreadful, home charging is likely your best option.
• Driving habits: If you primarily use your EV for short commutes and errands, home charging is usually sufficient. However, if you frequently take long trips or drive for work, public charging stations may be necessary.

Conclusion

The ideal charging solution for you will depend on your circumstances. In many cases, a combination of home and public charging is the most practical approach. When it comes to the question of which option is cheaper, charging at home is more cost-effective, but takes more time.
