What Are the Different Types of EV Chargers?

2022/06/16

EV charging refers to filling up your vehicle’s battery for it to operate, just like how you refill your gasoline car’s gas tank.  However, the charging mechanism isn’t as simple as refilling a gas tank, as there are many complexities involved in it. There are multiple types of EV charging connectors, and each of them offers different charging speeds.  In this post, we classify EV chargers based on their charging speeds and tell you how many types of EV chargers there are. But first, let’s talk about what an EV charger is.


What is an EV Charger And How It Works

Every battery-powered electric appliance needs to be charged to work. For example, you can’t use your phones or laptops without charging them first. When you charge them up, you’re essentially storing electric charges in the battery, which are later used to power the internals. In the same way, you need to charge your electric car to use it. While the overall size and the amount of power are vastly different from a mobile phone charger, the core principles are the same. To charge up your electric car, you need an EV charger. Just like a mobile phone charger, the adapter of an EV charger is plugged into a power outlet and it’s connected to the EV through a cable and connector. The power is then stored in the battery of the EV. 


There are two types of current: AC and DC. AC is used when you use an appliance by plugging it into power directly. On the other hand, DC is used when you store the power in a battery and use it to run the appliance later on. Before storing the power into the battery, the AC power is converted into DC, which could happen in the charger, or the EV itself. 

How Fast Charging Works 

If your charger and EV both support DC-type charging, the conversion is performed within the charger itself. So, all the heavy-duty work is done in the charger, which allows you to fast-charge your vehicle. With fast charging, you can fill up the juice of your EVs much faster.

 Types of EV Chargers 

1. Slow Chargers 

The first classification includes standard, slow EV chargers. These can output power from 3 kW to 6 kW. It’s often only used for home charging as the rating isn’t good enough for quick charging at a public charging station. Most slow chargers are rated for 3 kW — but this number is rounded off. In reality, a 3 kW charger actually produces 2.3 kW power. The most common accurate charging output of slow charges is 3.6 kW.  While the exact charging time depends on which car you’re charging with, a slow charger usually takes around 6 to 12 hours to charge a vehicle. Hence, slow chargers are good for charging an EV overnight at home. However, that doesn’t mean they’re strictly made for home use; they’re often implemented in workplaces and offices so the employees could charge their EVs conveniently. 


2. Fast Chargers 

As the name suggests, a fast charger can charge up your EV much quicker than a typical slow charger would. 

A fast charger is rated from 7 kW to 22 kW, and the charging speed of your EV will be determined by your fast charger’s specific rating. For instance, a 7 kW charger will most likely charge your vehicle in around 4-6 hours, which is a massive upgrade from a slow charger. If you have a 22 kW charger, you can expect to get the same vehicle charged up in under 2 hours. Most fast chargers are found in places like parking lots and supermarkets, where you’re very likely to park your EV for a couple of hours. However, there’s nothing stopping you from getting your own fast charger from a top-tier EV charger manufacturer like Besen. The most common rating of a fast charger is 7 kW, but 22 kW is a popular rating among fast EV charging enthusiasts. 


3. Rapid Chargers 

Last but not least, the fastest way to charge up an EV is through a rapid charger. As the name might suggest, these chargers are rated higher than the previous two and can output power up to 100 kW. However, the most common rapid chargers are rated from 43 kW to 50 kW.  These chargers are most commonly found on motorways and main roads, where people need to quickly fill up their EVs during transit. Furthermore, an obvious hurdle stopping the general public from getting a rapid charger is the cost.  In most cases, a 100 kW charger is referred to as an “ultra-rapid” charger, while the <50kW chargers are known as simple rapid chargers. If you get a 43-50 kW charger, you can expect your car to be filled up in around 30-45 minutes. This kind of charger provides the highest level of convenience to people, especially the ones who’re not into charging overnight. 


The Bottom Line 

EV chargers are rated for different power outputs which classify them as different types. Each type takes a different amount of time to charge up your EV. No matter which type you’d like to get, it’s essential that you get your equipment from a top-tier EV charger manufacturer.
