While owning a Tesla is easier now than it was before, Tesla owners can still have a lot of questions regarding the electrical needs of Tesla cars and Tesla chargers.
If you are still in the planning stages of getting a Tesla car or having a charger installed in your home, you will want to know all about Tesla charger amps. Here is what I found!
Tesla Charger Amps
Tesla charger amps vary per Tesla model, with the Model 3 Rear-Wheel drive having 32-amp and the Model S, X, Y, and Models 3 Performance and Long Range having 48 amps. While the model 3 Rear-Wheel drive requires a 40-amp circuit breaker for charging, the rest of the Tesla car models need a 60-amp circuit breaker.
In case you are interested to learn more about the charger amps of different Tesla models and whether certain amps can work with lower or higher circuit breaker amps, keep on reading!
How Many Amps Is A Tesla Charger?
Tesla creates chargers with various amperages depending on the needs of specific models. If you have a Tesla Model 3, the onboard charger will have 32-amp.
Meanwhile, a Tesla Model 3 with a long range battery pack will have a 40-amp onboard charger.
Meanwhile, the recommended circuit breaker for Tesla Wall Connectors can range from 40 to 100-amp.
Can You Charge A Tesla With A 30 Amp Breaker?
It is possible to charge a Tesla with a 30-amp breaker. However, using a 30-amp breaker is not recommended because the charging speed of your Tesla will be slow.
A Model X will normally have a maximum miles of range per charging hour of 14, and a Model S does only a little better by having a maximum miles of range of 17.
Nevertheless, if a 30-amp breaker is all you have to work with, charging your Tesla overnight should suffice to give you enough mileage to last a typical commute daily.
How Many Amps To Set Up 220 In The Garage?
Unlike other electronics which use 220V, the correct voltage for Tesla cars is 240V.
That said, If you plan to install a 240V outlet for the Mobile Connector (previously known as the Universal Mobile Connector), a 50-amp NEMA 14-50 outlet is your best choice.
What Size Breaker Do I Need For A Tesla Charger?
Determining the breaker size your Tesla car needs depends on the Tesla’s onboard charger. Currently, the Tesla models have either 48-amp or 32-amp.
Tesla Model 3 Performance, 3 Long Range, and Model S, X, and Y have 11.5 kW or 48-amp, which means they need to be connected to a 60-amp circuit breaker.
Meanwhile, the Model 3 Read-Wheel Drive only has 7.7 kW or 32-amp. As such, a 40-amp circuit breaker should suffice for charging.
How Fast Does Tesla Charge On 220V?
On a 220V system, a Tesla will take roughly an hour to power up from 40% to 80%. However, it will take around 2 hours to go from 80% to 100%.
At this rate, you will get around 10 to 60 miles per hour, but that output still depends on the Tesla model you have. Even at a lower rate, you can fully charge your Tesla overnight.
How Long Does It Take To Charge A Tesla On 110V?
On a 110V system, you can expect every hour of charging time to add roughly 3 miles to your Tesla car’s range.
Consequently, charging a partially depleted Tesla car battery would take around 13 to 14 hours. However, that is just to replace the 40 miles you may cover in a day.
Charging your Tesla car to 100% on a 110V system would require charging the car overnight from 6 in the evening until 7 in the morning.
How Fast Does A Tesla Charge On 240V?
How fast a Tesla can charge on a 240V system depends on the amperage of the circuit breaker and the model of the car.
If you have a 60 amp circuit breaker, the maximum range per hour of charge would be 34mph for a Model S, 30mph for a Model X, and 42mph for a Model Y.
Additionally, the charging speed per model goes down in accordance to the amperage of the circuit breaker.
How Many Amps Does A Tesla 3 Draw?
A Tesla Model 3 Standard Range typically draws up to 44 miles or range per hour of charging on a 60-amp circuit breaker.
On a 50-amp circuit breaker, the miles of range per hour of a Model 3 goes down to 37, and ona 40-amp circuit breaker, the miles of range per hour is reduced to 30.
How Long Does It Take To Charge A Tesla With A 50 Amp?
How long it would take to charge a Tesla with a 50-amp breaker depends on the Tesla Model. For a Model S, the miles of range per hour on a 50-amp is 29.
Meanwhile, a Model 3 Standard Range would have 37mph, a Model X would have 25mph, and a Model Y would have 36mph.
How Long Does It Take To Charge A Tesla With A 30 Amp?
On a 30-amp circuit breaker, a Model S would have a maximum charging speed of 17 miles per hour. Meanwhile, a Model 3 would have 22 mph, and a Model X would have 14mph.
Finally, a Model Y will have a maximum charging speed of 14 miles per hour.
Can I Use A 60 Amp Breaker For Tesla?
You can use a 60-amp circuit breaker for a Tesla. In fact, using a 60-amp breaker is highly recommended because that gives each Tesla model a faster charging speed.
With a 60-amp circuit breaker, you can cover upwards of 30 miles per charging hour for Tesla Models 3, S, X and Y.
Conclusion
Tesla charging speed depends on the amperage of the Tesla model’s onboard charger and the amperage of the circuit breaker.
Technically, a 60-amp circuit breaker is the best choice for all Tesla models because it gives you the highest miles of ranger per charging hour.
Nevertheless, circuit breakers with lower amperage should be enough if you have enough time to charge your Tesla car overnight.
