Most Tesla owners find that home charging covers the majority of their needs. It’s convenient, typically cheaper than public charging, and allows you to start each day with a full battery. Here’s a closer look at home charging costs and how to optimize them.
Home Electricity Rates
Your home electricity rate will play a major role in your charging costs. Rates vary depending on your region and can even change throughout the day. Understanding these rates is the first step to estimating your Tesla’s charging costs at home.
- How to Find Your Rate: Check your electricity bill to find out your rate per kilowatt-hour (kWh). For example, if you’re paying $0.12 per kWh and your Tesla’s battery holds 75 kWh, a full charge would cost about $9 (75 kWh * $0.12 = $9).
- Using Time-of-Use Rates: Some utility companies offer lower rates at night (off-peak hours) when demand is low. If your provider offers this, you can save money by charging overnight.
Installing a Home Charging Station
Using a standard outlet is possible, but many Tesla owners, including myself, install a Level 2 charger (such as the Tesla Wall Connector) at home. This option provides faster charging and is more efficient if you drive frequently.
- Installation Costs: A Level 2 charger installation generally costs between $500 and $1,500, depending on your home’s electrical setup. You’ll also need a certified electrician, which adds an extra $200 to $500.
- Long-Term Savings: Although there’s an upfront cost, charging at home long-term is often the cheapest and most convenient way to keep your car powered.
Charging Overnight to Save on Off-Peak Rates
Off-peak rates can save you a lot over time. I schedule my Tesla to charge overnight, which takes advantage of lower electricity rates and helps reduce my overall costs.
- Finding Off-Peak Hours: Check with your electricity provider or review your bill to see if off-peak rates are available.
- Savings Example: If off-peak rates reduce your cost from $0.12 to $0.08 per kWh, you could save $3 on each full charge, making a difference over time.
Tracking Home Charging Costs
Tesla’s mobile app provides an easy way to monitor each charging session’s cost and usage. I check my monthly totals in the app to keep track of how much I’m spending on charging and look for trends.
Charging on the Road: Tesla Superchargers
For road trips or emergencies, I rely on Tesla’s Supercharger network. Superchargers are fast and convenient but usually more expensive than charging at home. Here’s what I’ve learned about managing Supercharger costs.
How Superchargers Work and Cost Per kWh
Tesla Superchargers are designed for quick top-ups, allowing you to get a significant charge in under an hour. While convenient, the cost per kWh can be higher than home rates.
- Cost Per kWh: Supercharger costs vary by location but typically range from $0.25 to $0.50 per kWh.
- Idle Fees: Tesla also charges idle fees if you leave your car plugged in after it’s fully charged, encouraging people to free up charging spots.
Road Trip Costs and Calculating Total Charges
On road trips, I make use of Superchargers. Here’s an example calculation for a 300-mile drive, using a Tesla with a 75 kWh battery.
- Trip Example: If I need two full charges at $0.30 per kWh, each charge costs $22.50, for a total of $45 for the trip. It’s a simple way to plan for the cost of a road trip.
