Electric car owners are still concerned about how to choose an ev dc charger? This is because there are a variety of chargers available, each with different features. You need in-depth information to avoid the wrong charger selection.

This guide will help you avoid this and make the right choice. It caters to you with details on definitions, concepts, benefits, drawbacks, and much more. Sounds exciting? Let’s dive right in to uncover facts!

Home charging

Home charging refers to the charging operation that you carry out at home. Home chargers also refer to the level 1 charger. The output power of these chargers lies around 3.0 kW up to 7.0 kW. 

The reason why this charger refers to the home charger is that you can plug this charger into any home electric outlet. It only requires 120 V of electricity to facilitate the charging operation. 

Home charging

Get familiar with the main pros and cons of the EV charger right in the following section:

1. Pros

High accessibility

You can easily access the home charger and use them on the go. This is mainly because they support standard wall outlets for electricity needs. You can easily set up these chargers in your garage and at home.

Low cost

The price of ev charger will be relatively low compared with other chargers. You can quickly get this charger for $500 to $1000. Apart from this, the installation cost of this charger is also negligible. It does not require any extensive infrastructure or setup. 

Super convenient usage

Anyone can use this charger without any special training or knowledge. You just need to plug it into your vehicle, and the charging starts. When you have a home charger, you dont need to deal with the complex configuration and setup.  

Safe and secure

The lower output power ensures the safety of your vehicle and your electrical system. It does not put stress or overload on your battery system. Thus, you can enjoy the longer working life of your car or battery.

2. Cons

Slower charging

Charging on home chargers takes much time, so it refers to the overnight charger. It takes 5 to 12 hours to charge up your vehicle up to 80%. So if you are looking for the fast charging option, this is unsuitable.

Limited range of travel

The home charger does not allow you to enjoy a more extended range of travel. Instead you only get 5 to 10 miles within 2 to 3 hours. You can only travel short distances or cover long tours on the home charger.  

3. How long can it be used

The life of the level 1 charger under frequent usage can be anywhere from 5 years up to 15 years. This is because multiple factors affect the life of the home charger, such as:

Brand and quality

Choosing a home charger from a reputational and well-experienced brand lasts longer. Such brands use qualitative materials that contribute to the practical charger life. 


If you use your home charger daily, it won’t last longer. The expected life expectancy is around 5 to 8 years in this case. This is because frequent usage puts stress on the charger.

Environmental conditions

The environment where you use your charger significantly affects its working life. For instance high humidity, moisture, temperature, and sunlight affect the performance and efficiency with time. It also leads to wear and tear on the charger.

Charging at work

Charging at work refers to the charger you utilize in the workplace or during labor. You can put your vehicle on charging during your work hours (usually around 9 am up to 5 pm). This also refers to the level 2 charger.

The power output of this charger lies in the range of 7 kW up to 19 kW. You can plug this charger into a home outlet or 240 V outlet. The charging speed with this charger is faster than what the level 1 charger offers. 

Charging at work

1. Pros

Speedy charging

With one hour of charging, the level 2 charger offers you a travel range of 10 up to 25 miles. This is why you can charge your vehicle while working or performing daily duties at work. It is perfect for daily commuting. 

Wide compatibility

Almost every vehicle out in the market supports the usage of the work charger. This acts as the standard charging solution. You don’t need to worry about acquiring the specific connectors/adapters when using the working charger.  

Zero stress on battery

Charging with the level 2 or work charger will not put stress on your battery. The charging speed with a working charger is optimum (not very high or not very low). This increases the battery efficiency and effectivity. 

Cost effectivity

The work charger offers you higher cost-effectiveness. You can save up bucks in the long run. This is because it takes little time to charge. You can add this time to doing other valuable tasks or earning side money. You can get this charger for $500 up to $3000. Apart from this, the electricity bill cost remains stable. 

2. Cons

Installation barrier

You need a professional to set up your work or level 2 charger. You also need to put a shade over the charger to protect it. Both of these factors add up to the installation cost. 

Electrical requirement

You cannot put this charger in a 120 V outlet. But you need to put this charger in the 240 V outlet. If you don’t have this outlet, you need to upgrade the existing outlet. This further adds up to the cost of installation. 

No portability

The work chargers are hard-wired, meaning you cannot move this charge from place to place. There are some chargers that you can move. But you are not going to get a 240 V outlet quickly. Therefore, there are portability issues with this charger type. 

3. How long can it be used

The life of the work charger or level 2 charger ranges from 5 years up to 25 years. It depends if how you heavily use your charger; it will last 5 to 8 years. If you use it occasionally, it lasts up to 25 years. On the other hand, if you use it sparingly, it will last around 15 years.

Multiple factors affect the life of the work charger. For instance, charger material, build quality, brand, etc. Consider these factors while choosing the charger to make it last longer.

Public charging

The public charger refers to the level 3 charger or DC fast charger. These chargers are referred to as public chargers only because they are available for public use. Anyone can access and use these chargers.

These chargers are super fast, and you can charge up to 80% of your vehicle battery in only 15 to 60 minutes. The output power of public chargers is around 50 kW to 350 kW. You can easily find these chargers on travel corridors and highways.

Public charging

1. Pros

Super quick charging

You can charge almost full battery using the public charger within 15 to 45 minutes. This way, you can enjoy super convenience while traveling on long tours or trips. Public chargers are faster than level 1 chargers, as well as level 2 chargers. 

No range anxiety

With the level 3 or DC fast charger, you will not experience any range anxiety. With over 200 to 250 milers charging, you can easily cover longer distances easier. 

Best for fleets

You can charge up buses, taxis, or fleets on the go. This is because with only 15 to 30 minutes of charging per vehicle, you can charge up many cars instantly. 

2. Cons

High purchase cost

The cost of the DC fast charger is very high. In general, the price lies in the range of $ 15,000 up to $50,000 or more. Apart from this, the installation cost is also very high. This is because you need a well-established infrastructure for adequate weather protection. 

Limit in accessibility

There needs to be more DC fast chargers around the globe. This is because of the higher cost association and the fact that EV technology is still evolving. 

Stress on battery

The high-speed charging by the public chargers puts much stress on the battery. This ultimately contributes to the decrease in the capacity of each cell. This, in turn, collectively reduces the performance and efficiency of the storm. If you continue charging on DC fast chargers, this will affect your battery health and life. 

Negative environmental impact if rely on grid

To cater to the high-speed charging, you need a connection to the grid. If the grid runs on fossil fuel, you will contribute to the environment negatively. This will ultimately result in acid rain and a change in the climatic impact. 

3.Which connectors are available for public charging?

There are different types of connectors that you can use with the public charging. Some of the key connectors that you can use are:
