Frequently Asked Questions - Home Charging Installation

What's the best way to charge a Tesla?
We recommend plugging in every evening to top off the battery. This ensures you always wake up to a fully charged Tesla.

What percentage should I charge the battery to?
Adjust how full the battery charges from the charge settings menu. For regular use, we recommend keeping your car set within the 'Daily' range bracket, up to approximately 90%. Charging up to 100% is best saved for when you are preparing for a longer trip.

Should I wait for the battery to fully deplete before charging?
Tesla uses lithium ion batteries so there is no memory effect, this means there is no need to deplete the battery before charging. We recommend plugging in as often as possible.

Do I have to install a Tesla Wall Connector?
The Wall Connector is our recommended home charging solution, as it provides the most convenience and the fastest charging speeds. However, a Tesla can also be charged with the Mobile Connector or at universal charging stations with the included J1772 adapter.

How do I connect my Wall Connector to Wi-Fi?
By following the steps for connecting a Wall Connector to local Wi-Fi, you can ensure that your Wall Connector stays up-to-date with over-the-air firmware updates and remote diagnostics.

Can I use a normal 110 volt outlet to charge?
Yes. An adapter for a 110 volt outlet (NEMA 5-15) is included as standard equipment with all new Tesla cars. This provides approximately two to four miles of range per hour of charge depending on the car. For the best home charging experience, we recommend installing a Wall Connector.

How long does it take to charge a Tesla?
Charging time depends on the car and the connected power supply. Learn more about charging speeds of Wall Connectors at various power levels.

I have an existing 240 volt outlet in my garage. Can I use it?
There are many different types of 240 volt outlets. Tesla supports adapters for the most common outlets. Learn more about supported adapters.

I live in an apartment or condo. Can I still get Tesla home charging installed?
For customers who live in multi-family buildings, there may be additional levels of management approval before you can get started.

We've created a template to communicate the value of home charging for you and your building, to ensure all stakeholders are aware of your planned purchase, and desire to have electric car home charging options.

How much does installing a Tesla home charging equipment cost?
Cost varies depending on the home. You may want to get multiple installation quotes when working with independent electricians. Tesla provides a list of recommended electricians in your area who can provide you a quote.

How long does it take to install home charging equipment?
Home charging equipment installation can take several hours. More complicated jobs may take up to two days.

I have two Tesla cars. What’s the best option for charging both at the same time?
Installing two Wall Connectors configured for power sharing would be the best option. Power sharing capability for the Gen 3 Wall Connector is coming soon.

Why is Supercharging so much faster than charging at home?
Superchargers skip the onboard charger of the vehicle, providing up to 120kW of direct current (DC) power to the battery. This level of power requires dedicated transformers and utility connections which are not available in residential situations.

Can I just use a local Supercharger and skip charging at home?
The best charging experience will always be to charge at home. Plug in when you get home and wake up to a full charge. Many utilities offer low cost electricity at night to incentivize charging at home.

Where can I learn more about long distance traveling utilizing the Tesla Supercharger network?
Plan your route with the trip planner or see an overview of our current and future Superchargers.

What is Destination Charging?
We work with hotels, resorts, restaurants and other hospitality based locations to install Wall Connectors to enable charging when away from home. Learn more about Destination Charging.

I own a property with parking available to the public. How can I join the Destination Charging program?
Submit an application to become a Tesla charging partner.

Where can I find out more about incentives specific to home charging?
Home charging related incentives can be found on the U.S. Department of Energy Alternative Fuels Data Center.

Incentives specific to home charging installation are typically administered on a local basis, often as time-of-use electricity rates or rebates from utility providers. Contact your electric utility provider to find out if they have special rates for electric car charging.
