Tesla vehicles are meant to run on electricity rather than energy sources. But what happens if the electricity goes off (and users live in the woods) and you need to charge the Tesla?
There are very positive advantages to using a generator to charge a Tesla.
Either you’re planning a vacation in a distant location, or maybe even a due to natural calamity wipes out electricity for many days.
Nevertheless, it is critical to know if it’s doable and how to achieve it. So, can you charge the tesla with a generator?
Using 110 Voltage at 30 Ampare, many generators could recharge a Tesla.
Hydroelectric generators can increase the range by roughly 4 kilometers per hour.
Greater 240 Volts generators can increase battery capacity by approximately 30 kilometers per hour.
The least feasible way to recharge a Tesla is using a portable type generator.
They’ll function in a rush if you have the appropriate equipment.
This post will cover all you need to know about using a generator to recharge the Tesla.
Can You Charge An Electric Car With A Generator Or Backup Battery?
A generator or a backup battery can be used to charge your Tesla or any other electric vehicle but it is not simple enough to use any generator or backup battery. Let’s see the requirements for a generator to charge your electric vehicles like Tesla efficiently.
Standard Ways Of Charging EV
There are three standard ways of charging an electric vehicle. You can choose any of these methods to keep your electric vehicle running on the roads.
1. Level 1 Charging
The standard 120 V charging outlet is the first way of charging your electric vehicle but it would take somewhere around 40 hours to fully charge your vehicle and is therefore not an ideal way of charging any EV.
2. Level 2 Fast Charging
The second way of charging an EV is to go with the public charging points that offer 240V power and can also be installed in houses for faster charging. You can fully charge electric vehicles using these 240 Voltage power stations within 5 hours.
3. Level 3 DC Fast Charging
The third method is the commercial method of charging electric vehicles that you would have seen along freeways. This method relies on Direct Current DC chargers to instantly charge your vehicle and you will be good to hit the road within 30 minutes of using DC fast charging. But the downside of this method is that it requires extremely expensive charging outlets that are impractical and not affordable for houses.
Can You Charge A Tesla With A generator?
Many generators are viable emergency chargers for power outages, camping, or off-the-grid life that can generate enough power to charge Tesla.
Standard alternators can’t charge Tesla with DC but can trust with 110V, 120V, or 240V AC (albeit slowly).
Let’s talk a little more about alternators and how to utilize them for charging a Tesla.
The Charging Scenario Of Tesla:
Tesla’s charging system is robust, adaptable, and works in a few steps.
Tesla’s vehicles have onboard equipment that regulates (and sometimes converts) power to charge thousands of lithium batteries under the floor.
When the car is connected, the system determines whether it is getting AC power (AC) or DC power (DC) from the power supply.
Upon receiving a direct current, the current flows through the control system to the battery.
AC power goes through an onboard inverter and is converted to DC power that the battery can use.
The battery cell itself does not have a system to prevent overcharging.
Overcharging is dangerous due to the heat and damage it causes.
However, Tesla’s onboard computer monitors the state of charge and turns it off when the battery is full.
Sophisticated type systems perform with many different voltages and currents.
The generator is a type of engine that burns fuel such as gasoline and diesel with a machine to generate electricity.
Not all alternators are the same. Before choosing an alternator to charge your Tesla, it is important to understand the common types of differences.
The most common types of generators are:
1. Gasoline Type Generator:
You’re picturing a gasoline generator whenever people imagine such a generator.
They are perhaps the most prevalent and may be found in home improvement stores and recreational retailers.
Unlike gas generators using pressurized gas or LPG, gasoline generators use gasoline.
Gasoline generators are reasonably priced and usually start at around $250 to $300.
Most of these cheap units have a small fuel tank and do not generate much current but can generate 110V at 15A and, in some cases, more.
2. Diesel Type Generator:
Generators driven by diesel are far more effective than ones running on gasoline.
A tiny transportable diesel generator, on the other hand, is unlikely to be found.
Larger ones, including standby power generators and industrial sites, use diesel.
Numerous generators are more than capable of charging a Tesla.
3. Generator Using Natural Gas:
Usually, natural gas engines are located in rural residences.
Most natural gas-fired power units are stationary, which means they cannot be moved.
Most of these units automatically start and serve as a backup.
These generators are built to power a complete house for a long length of time.
They’re also frequently used in conjunction with solar energy.
4. Portable Ones:
Portable generators are the type that may be purchased at a hardware-type shop.
These engines are dependable, but the less expensive types aren’t built to operate for consecutive days.
They normally with between first and sixth electrical outlets and don’t come with a starter.
What Type Of Generator Is Required To Recharge A Tesla?
A Tesla may be charged by almost any generator capable of providing 110 to 120 Volts (at fifteen to thirty Amperes).
240 Volts generators are far better for the role, although even a tiny portable generator may recharge a Tesla to a certain level.
How Fast Can A Generator Charge A Tesla?
The generator does not recharge Tesla very quickly.
The charging speed you get is the same as what you get from a regular 120V wall outlet.
Charging at 110V or 120VAC is trickle charging, usually with a range of about 4 miles per hour connected to the system.
This is a charging range of about 30 miles per night, which is quite slow. However, upgrading to a 240v alternator can significantly improve charging speed.
This is the voltage at which the Tesla Wall Charging operates and can be set at speeds of 30 mph.
The Better Tesla Recharge Generator:
Generators are limited, and some are suitable for charging Tesla vehicles.
The small generator we recommend is about 6500 watts, which is the midrange of a portable petrol model.
A 9000w or 10000w generator is a big improvement and probably more efficient.
An ideal one would include an integrated fixed natural gas or diesel generator connected to a household electrical system.
Combined with a Tesla power wall or wall charger, it seamlessly charges your Tesla at the same speed as your mains and with cleaner emissions than your portable device.
An ideal generator and Tesla charge come with a 240v socket.
A 110V alternator can be used, but charges at less than 1/5 speed.
The 240V alternator charges faster than Tesla, offering significantly better range and lower fuel consumption.
What Is Important To Us When Choosing A Tesla Gas Generator?
When choosing a Tesla gas generator it is important to look for the following specifications of the generator and compare the two models. Choose the one with better specs.
- Outlet Types
- Parallel Combination Support
- Fuel Consumption
- Running Time
1. How Big Of A Generator Do You Need To Charge A Tesla?
If there is no power left in your Tesla that is it is at 0% battery level then charging it up to 100% will require the services of a 1500 watts generator. If you utilize a generator with lower rated wattage the Tesla will not be fully charged as the runtime of your generator will soon be over and no more power could be drawn from the generator before refueling it.
2. How Long Would It Take To Charge A Tesla With A Generator?
The charging time of Tesla depends upon the voltage of your charger and the intensity of the power supplied to your vehicle. Using a standard 110V electric outlet for charging your Tesla will require you to wait for 7 hours approx. while the 220V outlet will reduce the charging time by half. On the contrary, if you use a supercharger site, it will make your Tesla ready to hit the road within 60 to 75 minutes.
3. How Many Watts Do You Need To Charge A Tesla?
Tesla like all other electric cars is designed to use a large amount of power and to refurbish that used power, large wattage is required to charge a Tesla. A standard 1500 watts portable generator will require 24 hours to fully charge your Tesla and not all portable generators can do so. Therefore, the standard generator wattage used for charging a Tesla is around 4000 watts.
4. Can I Use A Generator To Regularly Charge My Tesla?
Using a generator to regularly charge your Tesla is an impractical, uneconomical, and environmentally unfriendly option. This is because generators use gasoline or other fuels that are not very eco-friendly and also require a certain running cost that is not the best option to follow particularly when other economical and eco-friendly options of charging your electric car are available at hand.
5. Can I Parallel Two Generators To Charge My Electric Car?
Yes, you can parallel two generators to charge an electric car provided that your generator support parallel capability. To parallel two generators, you would have to follow the manufacturer’s instructions to safely make a connection between two units. Some generators support cross-brand parallel capabilities while some brands like Generac restrict the parallel combinations with the same manufacturing firm units.
6. Is It Possible To Charge An Electric Car With A Power Extension Cord?
It is definitely possible to charge your electric vehicle using the power extension cord but you can just use any multi-socket extension cord to do. You would have to go with an extension lead that follows US safety standards and comes from a credible manufacturer as well as a reliable and reputed seller. Before heading for the purchase, you need to go through the recommendations for EV drivers for purchasing an extension cord.
7. How Do I Prepare To Charge My Car With A Generator?
To prepare a generator for charging your electric car, you would first have to ensure that the generator is properly grounded. An ungrounded generator is not fit for charging your Tesla. Therefore, start with grounding your generator and keep the recommendations for grounding a generator in mind. You can follow the recommendations for grounding a generator provided in the user’s manual of each generator model.
