A Beginners Guide to Commercial EV Chargers

As we stand on the cusp of a new era in transportation, the ubiquity of electric vehicles (EVs) is an undeniable reality. This transition isn’t solely propelled by the vehicles themselves but significantly hinges on the very backbone of EV technology: commercial EV chargers. They are the unsung heroes, ensuring our vehicles are powered and ready to traverse the miles ahead. But what exactly are these chargers, and how do they operate? That’s what we’re about to unravel in this comprehensive guide.

Understanding EV Chargers

Before we delve deeper into the subject, let’s establish a basic understanding of EV chargers. EV chargers function as the middleman in the process of powering your electric vehicle. They facilitate the transfer of electricity from a source, like the electrical grid or a dedicated battery bank, to the battery pack within your EV. Simply put, they serve as a conduit to funnel electricity into your vehicle, similar to how petrol stations work for conventional fuel-based cars.

The Basics of EV Charging

Charging an electric vehicle might seem like a simple process of plugging in a cable, but it involves a lot more than that. Charging an EV is akin to filling a glass with water. It’s not just about how fast the tap can pour the water (charging power) but also how much water the glass can hold (battery capacity) and how quickly it can take in the water (charging speed). Every EV is unique and has its own set of charging specifications and requirements, so understanding these basics is paramount.

Types of Commercial EV Chargers

While all EV chargers essentially perform the same function, they’re not all created equal. There are three primary types of commercial EV chargers – Level 1, Level 2, and DC Fast Chargers. These categories aren’t merely about one being better than the other; instead, they cater to varying charging needs and circumstances.

Level 1 EV Chargers

Starting with Level 1 chargers, these are essentially the starter pack of EV charging. They’re pretty much your standard household plug but tailored for EVs. While they don’t require any special installation and are quite affordable, they offer relatively slow charging speeds. They typically provide around 3 to 5 miles of range per hour of charging, meaning a full 8-hour overnight charge might only yield 24-40 miles of range. That’s perfectly fine if you’re only driving short distances each day, but for heavier usage or commercial purposes, you might need something with a bit more oomph.

Level 2 EV Chargers

This brings us to Level 2 chargers. If you’re looking for a speedier charging solution, these chargers might be your cup of tea. Offering 10 to 60 miles of range per hour of charging, they’re a substantial upgrade from Level 1 chargers. However, this faster charging speed comes with a catch: they require a dedicated circuit and professional installation. Level 2 chargers are commonly found in commercial settings such as offices, shopping centres, hotels, and public charging stations. They provide a balance between speed and cost, making them an excellent choice for many businesses.

DC Fast Chargers

Next up, we have the powerhouses of EV charging – DC Fast Chargers. These are the cream of the crop, offering rapid charging speeds that can provide up to 60 to 80 miles of range in just 20 minutes of charging. However, these high-octane chargers require a significant investment and specialised installation. Due to their high cost, they’re often deployed in high-turnover locations, like motorway service stations, where EVs need to be charged quickly.

The Importance of Commercial EV Chargers

Commercial EV chargers are more than just tools for charging vehicles. They’re strategic assets that can encourage the widespread adoption of electric vehicles, making them a crucial part of the future of transportation. By providing reliable and convenient charging options, commercial EV chargers can alleviate “range anxiety” and increase the appeal of EVs to potential buyers.

Advantages of Commercial EV Chargers

Commercial EV chargers offer a wealth of benefits, especially for businesses. By installing these chargers, businesses can attract eco-conscious customers, encourage their own staff to switch to EVs, and even turn a profit by charging for the service. In addition, having commercial EV chargers in place can bolster a company’s Corporate Social Responsibility (CSR) initiatives, demonstrating a commitment to environmental sustainability. For consumers, commercial EV chargers ensure they’re never too far from a charging point, adding convenience and peace of mind.

How to Choose a Commercial EV Charger

Choosing a commercial EV charger isn’t a decision to be made lightly. It requires careful consideration of various factors, including power level, installation requirements, cost, and compatibility. Let’s explore each of these in detail.

Power Level

Power level is a critical factor to consider when choosing a commercial EV charger. Level 1 chargers might be suitable for home use or businesses with long dwell times, but for most commercial applications, Level 2 chargers or DC Fast Chargers are likely more appropriate. While Level 2 chargers offer a balance between cost and speed, DC Fast Chargers can deliver a significant charge in a very short time, making them ideal for high-traffic locations.


While it might seem tempting to opt for the highest power level, remember that higher power chargers require more complex installations. Level 1 chargers can be plugged into a standard socket, while Level 2 chargers need a dedicated circuit and professional installation. DC Fast Chargers, being the most powerful of the lot, require a high-power electrical connection, often necessitating modifications to the existing electrical supply.


Cost is an inevitable consideration in any business decision. While Level 1 chargers are relatively inexpensive, they also provide the slowest charging speeds. Level 2 chargers are a step up in both cost and performance, while DC Fast Chargers are the priciest option but offer the fastest charging speeds. When considering cost, remember to account for both the charger’s price and the installation expenses.


Finally, consider the types of EVs you expect to charge. While most chargers are compatible with a wide range of vehicles, some are exclusive to specific makes or models. Checking compatibility ensures your chosen charger will meet your customers’ needs.

Best Practices for Using Commercial EV Chargers

Using commercial EV chargers requires a certain level of care and responsibility. Safety should always be paramount. Ensure that chargers are installed by certified professionals and regularly inspected for any signs of wear and tear. Keep the area around the charger clear of any potential obstructions, and adhere to all manufacturer instructions and guidelines.


Embracing the future of electric vehicles isn’t merely about welcoming these high-tech machines onto our roads. It involves developing a robust infrastructure that can reliably power these vehicles. Commercial EV chargers play a pivotal role in this landscape, enabling businesses to support the green revolution, attract eco-conscious customers, and contribute to a sustainable future. By understanding the different types of chargers and how to select the right one, businesses can make informed decisions that align with their goals.

Can all electric vehicles use any commercial EV charger?

While most commercial EV chargers are designed to be compatible with a wide range of vehicles, there are some that are exclusive to specific makes or models. Always check the charger’s specifications and the vehicle manufacturer’s recommendations before use.

How long does it take to fully charge an EV?

Charging times vary based on the type of charger and the specific EV model. With a Level 1 charger, you’re looking at up to 8-12 hours for a full charge. A Level 2 charger can do the same job in 3-8 hours, while a DC Fast Charger can deliver an 80% charge in as little as 20-30 minutes.

Are commercial EV chargers safe to use in any weather?

Most commercial EV chargers are built to be robust and weather-resistant, making them safe to use in a variety of weather conditions. However, as with any electrical equipment, it’s essential to adhere to the manufacturer’s guidelines and exercise due caution in extreme weather conditions.

Do commercial EV chargers require regular maintenance?

While EV chargers are relatively low-maintenance devices, it’s recommended to inspect them regularly for any signs of damage or wear and tear. Any identified issues should be promptly addressed by a professional to ensure the safety and functionality of the charger.
