There are several things you should know about charging your Tesla at home
How to Charge
Charging is easy for anyone who has a garage or carport with electric service. I’ve been driving electrically for four years. My first electric car was a Chevy Volt. I got it in 2017. I could have bought the Bolt EV, but I was chicken so I went with the Volt plug-in hybrid. It was nice getting my first 50 miles on any given day by electricity. I used gas only after the battery ran down. Most days, I didn’t use any gasoline. My gas mileage, according to my app was around 200 miles per gallon. I never bothered to get a 220-volt level 2 charger for my garage. An ordinary 110-volt circuit worked fine with the charger that came with the Volt. Even when the battery was fully discharged at the end of the day, it would be full by morning.
When I bought the Tesla, since it was during the pandemic, I did the same thing. I just plug the Tesla into the 110-volt wall socket using the charger that came with the car. You gotta remember that if you don’t drive much, you don’t have to worry about not having enough time to fill the battery by morning. Once the pandemic ends, I’ll get an electrician to put in a 220-volt plug for the Tesla. The Volt can stay with its 110-volt circuit.
People who live in an apartment and who don’t have access to an outdoor electric socket probably shouldn’t get an electric car yet. Eventually, there will be infrastructure available for you, but not now. Once you start driving electric, you’ll never want to go back.
How Long Does it Take to Charge?
The time needed to charge depends on how much you drove during the day and how much you expect to drive the next day. If you didn’t drive at all, something that happens often during the pandemic, it doesn’t take any time at all to charge. Tesla recommends that you not charge to 100% unless you’re about to set out on a long trip. I set my car to charge to 80%. I have my charge cable plugged in to a 15 amp circuit, and the car is set to draw 12 amps. My screen tells me that the battery is gaining 6 miles of range for every hour of charging. So with the 110-volt circuit, the Tesla charges at about the same rate as the Volt. When the pandemic ends, I’ll get an electrician to wire up a 60 amp circuit to the circuit breaker box, and I’ll install a level 2 charger. That will allow me to gain around 30 miles of range for each hour of charging. The state of Maryland and the electric company will cooperate to give me a tax break that will save me about 30% of the cost of installing the level 2 charger.
What do you need?
What you need depends on what you already have. Remember, we’re talking about someone who lives in a house with either a garage or a carport. If you keep an electric dryer in or near the garage or carport, just use the charger that comes with your Tesla. It has the adapter for a 110 volt receptacle, If you have a dryer circuit close to or in your garage, just buy the proper adapter from the Tesla store and you’re in.
What does it cost?
Otherwise, you’ll need an electrician to install the proper circuit for a 220 volt receptacle near the place where you plan to park the car. Then you can still use the charger that comes with the car, or you can spend about six hundred dollars and buy a wall mounted charger. As far as what the electricity will cost, it’s less than gasoline. This website estimates the cost of electricity needed to charge a Tesla.
What it says is that it costs around $3.00 to get 100 miles of electricity for a Model 3 and around $4.24 to put 100 miles of electricity in a Model X. So if you’re not getting around a hundred miles to the gallon of gas, electricity is cheaper than gas, and you don’t need to go to a gas station. You don’t even need to bother with charging stations unless you’re on a road trip. You just plug in when you get home, and your car is charged to 80% in the morning.

The massive legislative effort titled the "Big Beautiful Bill" is taking direct aim at what has become one of Tesla’s most critical and profitable revenue streams: the sale of US regulatory credits. The bill could eliminate billions of dollars from Tesla’s bottom line each year and will slow down the transition to electric vehicles in the US.
The financial stakes for Tesla are absolutely immense. In 2024, Tesla generated $2.76 billion from selling these credits. This high-margin revenue was the sole reason Tesla posted a profit in Q1 2025; without the $595 million from regulatory credits, Tesla’s reported $409 million in profit would have been a $189 million loss.
How the ZEV Credit System Works
Zero-Emission Vehicle (ZEV) credits are part of state-level programs, led by California, designed to accelerate the adoption of electric vehicles. Each year, automakers are required to hold a certain number of ZEV credits, with the amount based on their total vehicle sales within that state. Under this system, automakers that fail to sell a certain percentage of zero-emission vehicles must either pay a significant fine or purchase credits from a company that exceeds the mandate.
Automakers who fail to sell enough EVs to meet their quota have a deficit and face two choices: pay a hefty fine to the state government for each missing credit (for example, $5,000 per credit in California) or buy credits from a company with a surplus.
As an all-EV company, Tesla generates a massive surplus of these credits. It can then turn around and sell them to legacy automakers at prices cheaper than the fine, creating a win-win scenario: the legacy automaker avoids a larger penalty, and Tesla gains a lucrative, near-pure-profit revenue stream.
This new bill will dismantle this by eliminating the financial penalties for non-compliance, which would effectively make Tesla’s credits worthless. While the ZEV program is a state law, the Big Beautiful Bill will fully eliminate the penalties at a federal level.
A Multi-Billion Dollar Impact
The removal of US ZEGV credits would be a severe blow to Tesla’s financials. One JPMorgan analyst estimated that the move could reduce Tesla’s earnings by over 50%, representing a potential annual loss of $2 billion. While Tesla also earns similar credits in Europe and China, analysts suggest that 80-90% of its credit revenue in Q1 2025 came from US programs.
Why the Program Exists
While the impact on Tesla would be direct and immediate, the credit system has a wider purpose. It creates a strong financial incentive for legacy automakers to develop and accelerate their zero-emission vehicle programs, whether it’s hydrogen, electric, or another alternative.
Eliminating the need for these credits would remove that financial pressure. This could allow traditional automakers to slow their EV transition in the US without the fear of a financial penalty, potentially leading to fewer EV choices for consumers and a slower path to vehicle electrification in the country.
Big, But Not Beautiful
On Sunday Morning TV, Elon Musk was asked his thoughts on the Big Beautiful Bill. They were pretty simple. A bill could be big, or it could be beautiful - I don’t know if it can be both, Musk stated.
Elon Musk in new interview: "I was disappointed to see the massive spending bill, frankly, which increases the budget deficit and undermines the work the DOGE team is doing. I think a bill could be big, or it could be beautiful—I don't know if it can be both." pic.twitter.com/DnyjHN7xCY
The bill poses a threat to Tesla’s bottom line and to the adoption of EVs in the US market, where automakers will no longer have a financial incentive to transition to cleaner vehicles, a market they’ve regularly struggled in when competing against Tesla.
Tesla will have to work carefully in the future to cut expenses to remain profitable after the elimination of these regulatory credits.
Tesla is rolling out a thoughtful and much-needed update to its in-vehicle Supercharger UI. The update is designed to provide drivers with details about Superchargers and their locations.
The update will add new icons and contextual messages to clarify Supercharger access requirements or restrictions, such as paid parking. There’s nothing worse than navigating to a Supercharger only to find out it's only for customers, requires paid parking, or some other service.
The new details will appear in various locations, including the Supercharger list, Supercharger module, and above the navigation directions when navigating to a Supercharger.
The new Supercharger icons will indicate the following requirements:
Valet-only Parking
Pay to Park
Access Codes
Parking Floor (the floor the Supercharge is on in a parking garage)
These icons are initially displayed when you’re searching for a Supercharger in the list of Superchargers. Additionally, when navigating to a site that includes any of the above, your vehicle will now display specific alerts for access requirements.
Access Codes and Parking Floor information will be provided above the navigation card when you reach the destination.
Solving Common Frustrations
Not a Tesla App
While these may seem like minor tweaks, they are a direct solution to some long-standing and common frustrations for many Tesla owners. Many drivers have likely experienced the scenario of following navigation to an unfamiliar urban Supercharger, only to arrive and discover it’s buried deep within a paid parking garage, with no advance warning of the fees or specific floor location.
This update provides all the critical information upfront so that drivers can make informed decisions on where they would like to charge. No more surprise parking fees, no circling a multi-level garage at 3% battery, desperately searching for the red and white Supercharger signs, and no more getting stuck searching for an access code to charge.
Little Details Matter
These Supercharger updates are the definition of quality-of-life improvements. Little details that make a big difference in usability.
As the Supercharger network continues its massive expansion into more complex and densely populated urban centers, providing this kind of granular, logistical data becomes increasingly important.
Release Date
While Tesla hasn’t announced when these features will be added, they’ll likely be included in the next major Tesla software update, presumably update 2025.24 or 2025.26.
The Tesla app was recently updated to v4.46.5 and added the ability to restrict location visibility for other drivers of the vehicle. Although the app update didn’t include these Supercharger updates, we expect these new Supercharger details to also be added to the Tesla app soon.
