Exciting news about the Tesla Semi has been circulating, and as a curious individual, I was eager to learn more about its charging capabilities.
After conducting extensive research, I am impressed with the charging time of the Tesla Semi truck.
Tesla Semi Truck charge time is remarkably quick, typically taking no longer than 40 minutes to an hour. Of course, the exact duration can vary depending on certain factors, but overall, it’s quick and efficient.
If you’re interested to learn more about their charging lifespan, then you’re in luck! Keep reading this comprehensive guide to discover everything you need to know.

Estimating Tesla Semi Truck Charge Time!
With the new Megacharger innovation, the Tesla Semi will take no more than 40 minutes to 1 hour to charge completely.
The Megacharger is quite faster in comparison to 20x home charger usage to charge the truck. However, this can’t charge the Tesla cars even if it’s super rapid. For this purpose, you’ll need the home charger. Ensure to check whether is Tesla home charger worth it or not!
Back to the topic, you’ll need to know about the charge wattage and capacity of the battery pack in order to figure out the charge time of the Tesla Semi. These 2 elements play a vital role that causes the charging speed to increase or drop.
Well, the Megacharger network allows Tesla semi-truck battery packs that contain 400 – 500 miles of mileage with 900 kWh of capacity to get recharged using the 1,000 kWh or 1 MWh charge wattage.
To get the point clearly, here’s how you can calculate the charge time in the simplest way using the charge wattage and battery capacity:
Charge Time = (Battery Capacity x 70% – 80%) / Charge Wattage
= (900 x 70% – 80%) kWh / 1,000 kWh
= (630 – 720 kWh / 1,000 kWh) X 60
= 38 – 43 minutes
Note: In most cases, you might need to count 70% to 80% as the battery pack is suggested to never charge fully. Otherwise, the charge time would be 1 hour due to no limitation of charge.
How Long Does A Tesla Truck Take To Charge?
As Tesla contains 2 types of trucks which are Cybertruck and Semi, both require similar time to charge even if using different methods.
It’s clear that the Tesla Semi takes not more than 1 hour to charge completely using the Megacharger station. Then again, the Cybertruck requires more than 40 minutes to charge from 5% to 70% using the Supercharger V3.
However, if talking about the latest Supercharger V4 station, the Cybertruck will need around 20 – 25 minutes to charge.
Other than this, using it on a regular charger in a charging station will require more than 21 hours and 30 minutes to charge from 0% to 100%.
To understand it better, be sure to read how Tesla charging stations work!

How Much Does It Take To Charge A Tesla Semi!
Most of the time, the cost of charging the Tesla Semi will vary based on location. In some areas, it costs not more than $0.20 per mile to use the Megacharger station.
On the other hand, you’ll find $0.24 per mile in some areas using the same charging station. However, the cost won’t be higher than $0.50 per mile no matter what.
Previously, Tesla owner aka Elon Musk stated that the cost would be less than $0.07 which is far from the truth!
Be sure to check Tesla charging cost if you are wondering about the cars and compare it with the semi-trucks.
How Long Will Tesla Semi Truck Battery Last!
According to Tesla, the battery pack will last for around 500,000 miles or more based on the level of use and degradation.
It can last even longer than this if you regularly maintain and care for the battery by doing a healthier charging habit.
Once you are near or cross this limit that the Tesla offer in semi-truck models, it gets essential to replace the battery.
Wrapping Up
Knowing the estimated Tesla Semi truck charging time is crucial information for any owner or enthusiast. Waiting for a charge can feel like a drag, but with this knowledge, you can plan ahead and make the most of your time.
I’m glad to have provided you with valuable information, and I hope to do that more often in my new guides in future. So look forward to it!
