What Is A Level 4 EV Charger?

Level 4 EV charging systems may seem to be a daunting piece of equipment. There are a few different options when it comes to selecting an EV charger so it can seem to be a difficult choice.  If you happen to own an electric vehicle it is important to know the difference between these different options, and if you are looking to buy an electric vehicle it is just as crucial to know these differences!

This leads to the question, what exactly is a level 4 EV charger? A level 4 EV charger is the highest level of the electric vehicle chargers and is able to produce the most charging power out of all four of the current EV charging levels on the market. These chargers are very expensive but they give the fastest charge.

In order to fully understand how this works, it is important to understand the difference between AC and DC current. In this article, we will cover this topic as well as what it takes to install a level 4 EV charger.

So, What Is A Level EV 4 Charger?

A level 4 EV charger is a “supercharging” station that is able to quickly recharge an electric vehicle. At the moment, it looks to be that only Tesla has produced a “level 3 supercharging station”, which is considered to be a level 4 charger. There are not a lot of these chargers on the market, but in the near future, there will be more as the demand for faster- charging increases.

Tesla’s supercharger can recharge a vehicle up to 80% in just 20-30 minutes. With the up-and-coming level 4 chargers, there are more opportunities for different applications of charging, as they can produce over 150 kilowatts. That amounts to over a million volts of electricity. Needless to say, the level 4 EV chargers will allow for very fast charging times.

The proposed level 4 EV chargers will decrease charging time and still be able to provide just as much range as a level 3 charger. Fewer wait times and a faster charge are a great way to go when looking at buying a charger. There are some questions that may arise when looking into this level of electric vehicle charger, so let’s get into it.

How Does A Level 4 EV Charger Work?

As stated before, a level 4 EV charger is easily understood when AC and DC current is also understood. Alternating current (AC Current) is an electrical term that refers to the current of electricity that constantly moves back and forth. Direct Current (DC current) refers to the current of electricity that travels in one direction.

Alternating current is what we find in a typical household outlet. These sockets will always have 120 volts running through them. The current is flowing back and forth, allowing the plugs to work correctly no matter how they are plugged in. On the other end, we have a direct current that flows in only one direction. Why is this important when it comes to electric vehicle chargers?

Because level 4 EV chargers are the highest level of chargers, they put out the most amount of voltage for all four of the chargers. In order to accomplish this task, they must tap directly into the power grid so that they can pull direct current to charge an electric vehicle.

EV chargers that are level 3 and 4 should only be installed by a professional technician because they must tap into the power grid directly. Many of these sorts of chargers are what will be found at gas stations, hotels, or other public areas that are able to access the power grid and supply the correct type of power for charging.

Can I Install A Level 4 EV Charger In My Home?

Installing this level of charger will be more difficult and much more expensive than a level 1, 2, or 3 EV charger. This is because they do require a direct connection to the power grid and most houses are not set up for this sort of installation.

A level 2 charger (which will be covered a bit more in-depth in a later section) will typically cost anywhere from 2,000-5,000 dollars depending on what is bought. This is a cost-effective route to take when owning an all-electric vehicle. These chargers can be installed in a home and used without too much issue.

A level 4 EV charger will cost closer to 15,000 dollars alone without installation. They also have a large unit that comes with the installation and so finding the space to put everything will be quite a task. Many of these chargers can be found at gas stations, hotels, or other local areas because they have space to put the larger units as well as the ability to tap directly into a city power grid.

Where Can I Buy A Level 4 EV Charger?

Unlike a level 1 and level 2 charger, level 3 and 4 chargers are a bit more difficult to come by as they are considered to be the highest level of charging available on the market, right now. There are online dealers that do sell level 4 EV chargers; however, you typically must call to get a quote from them on how much it will cost to buy and install.

It is not quite clear if level 3 and 4 EV chargers will become extremely accessible to buy for personal use. Since they are becoming more prevalent in most communities, they can easily be used at gas stations, hotels, and other public areas. But most cannot be found in homes.

The biggest part to consider about a level 4 EV charger is that it would take a professional technician to install it. While you could just plug in a level 1 or 2 chargers a level 4 would take quite a bit more time to install. Another

What Is The Difference Between A Level 1, 2, 3, And 4 EV Charger?

After all this, you may be wondering what all the fuss is about when it comes to the different levels of EV chargers. It is helpful to know the difference between these chargers and the capabilities and drawbacks that each one has in order to decide what will be best for you.

A level 1 charger comes standard with any electric vehicle that you buy. This will be a normal charger that can plug into a regular 120-volt outlet in your house. The best part about this charger is the convenience of it. Since it comes with the vehicle, you can be assured that you will be able to charge the vehicle. The largest drawback of this charger is that the total charge time takes quite a bit of time.

On average, you are able to get about 50 miles worth of range after having charged the vehicle for 10 hours. This is owing to the fact that the outlet is only a 120-volt outlet, and it takes considerable time to charge a vehicle with a level 1 EV charger. These chargers are only made for personal use and for smaller machines, like a toaster or phone charger.

A level 2 EV charger is quite similar to a level 1 charger as you can plug it into an outlet just the same, however, instead of a 120-volt outlet, level 2 chargers require a 240-volt outlet. These outlets produce more voltage to give more power when charging. They can be hardwired into a home just as a 120-volt outlet can be and so they can be used for both personal uses as well as commercial use.

With a level 2 EV charger, you can fully charge an electric vehicle in about 10 hours. This is a great way to go when looking at purchasing a charging system for your house, as it can be installed easily in a home. You will need to find a company or technician that will install a 240-volt outlet in your home, and you will be able to charge your electric vehicle at a more efficient rate and get back on the road quickly!

A level 3 EV charger utilizes the same direct current that a level 4 EV charger does, allowing the electric vehicle to be charged in close to an hour! Much like a level 4 charger, these are mainly found in commercial areas where they can receive direct current to provide that much power.


The ability to charge your vehicle with a level 4 EV charger is an amazing feature, however, the cost and labor that it would take to install a level 3 or 4 charger in your house may be too extensive to make it worth the purchase, but with the possibility of these chargers becoming available for personal use, it is an exciting prospect.

With the price of these chargers, it should be considered whether it is something to pursue for your own personal use. There are enough level 3 chargers for the public to use that there shouldn’t be a huge demand at the moment. If the world is truly considering going fully electric, then there will be a great demand for level 4 EV chargers!
