How to prepare your workplace for installing EV charging stations

The Rise of EV Charging at the Workplace

Electric vehicles (EVs) are becoming increasingly popular around the world, with global sales exceeding 10 million for the first time last year. As more people switch to electric mobility, workplaces are beginning to see the value in offering EV charging as part of their employee benefits and sustainability efforts.

In fact, workplaces are now the second most common place for EV drivers to charge their cars. With this trend expected to grow, it’s important to plan carefully before installing any charging infrastructure.

Setting up EV charging isn’t just about buying a station and plugging it in. It involves understanding your location, electrical system, and future needs. Let’s explore the four key considerations for installing EV charging at your workplace.

1. Build a Strong Business Case for Workplace EV Charging

Before diving into the technical details, take a step back and think about the bigger picture. Installing EV charging is a significant investment, so you’ll need a solid business case to justify the cost and show the return on investment.

Consider the demand for EV charging at your workplace. Are your employees likely to use it? Will you offer it as a benefit or even monetize it by allowing public access? These decisions will shape the type and number of chargers you choose.

Also, understand the difference between AC and DC charging. AC is slower but more affordable, while DC offers faster charging at a higher cost. Choose based on your users’ needs and how often they’ll be using the stations.

Don’t forget about government incentives, which can help reduce costs. However, there may also be additional expenses, such as utility upgrades or permits, depending on your location and the type of charger you install.

It’s crucial to do your research early on, especially if you have multiple locations. Planning ahead will save you time and money down the line.

What Type of Charging Station Do You Need?

The type of charging station you choose depends on how it will be used. For example, if your employees stay all day, slow AC charging might be sufficient. But if your workforce comes and goes frequently, fast DC charging could be a better fit.

You might also find that a mix of AC and DC chargers works best, giving you flexibility for different users and scenarios. This way, you can accommodate both regular commuters and occasional visitors.

2. Prepare Your Workplace for Installation

Once you’ve built a solid business case, the next step is preparing your workplace for installation. Unlike standard electrical devices, EV charging stations require special wiring and a direct connection to your building’s power supply.

If your current meter isn’t powerful enough, it may need upgrading. The number of charging stations and their power output will also affect the complexity of the installation.

Remember, this is not a DIY project. You’ll need a qualified electrician to handle the work, which adds to the overall cost. Be sure to factor this into your budget from the start.

3. Conduct a Detailed Site Analysis and Evaluate the Grid Connection

Before finalizing your EV charging plan, conduct a thorough site analysis. Every location has its own set of constraints, and understanding these is key to a successful installation.

Location-Specific Needs and Limitations

Start by checking the availability of parking spaces. If your lot is already full, you’ll need to decide how many spots to convert into EV charging bays. Also, consider whether each station should have multiple ports for simultaneous charging.

Choose a location that provides easy access to your building’s electrical circuit to minimize costs and disruption during installation. Also, consider the size of the charging station—some models are wall-mounted, while others stand independently.

DC chargers are generally larger than AC ones because they require additional equipment to convert AC power from the grid into DC. This means you’ll need more space for DC units.

Electrical Capacity and Grid Connection

The number of chargers you install will impact your building’s electrical system. A single station may not cause issues, but multiple stations could require an upgrade to your electrical infrastructure.

Your location’s proximity to the grid can also affect costs. Sometimes moving a charging station just a few meters can make a big difference. To get a clear picture of what’s possible, consult with your utility company for an assessment of your current setup.

Getting More Grid Capacity Is Expensive

Upgrading your building’s electrical capacity can be costly. Hanno Klausmeier, Director of SAP Labs France, found this out when he installed EV charging stations and needed more grid capacity. Instead of paying for expensive upgrades, he explored alternative solutions like renewable energy integration and on-site storage batteries.

 

Hanno’s experience shows that creative solutions can often be more cost-effective and sustainable in the long run. Don’t rush into the first option presented—evaluate all possibilities before making a decision.

4. Have a Future-Proof Outlook

EVs are here to stay, and their popularity will only grow in the coming years. That’s why it’s important to design your charging infrastructure with the future in mind.

Consider trends in EV ownership among your employees and customers. Add a buffer to your plan to account for potential growth. You might choose to install more stations than currently needed or ensure your infrastructure can easily support future additions without major upgrades.

As Linda Grave, CEO of EV driver, said in a recent REVOLUTION Live podcast:

“Don't just build charging infrastructure that meets today’s requirements or needs, they should prepare for the next phase. And this starts with the groundwork, the construction, and everything you're laying, whether it be water, electricity, gas, or whatever it might be, this is the time to be thinking about future-proofing your site.” – Linda Grave

 

Other Tips to Get Started with Workplace EV Charging

While the initial cost of installing EV charging stations can be high, it’s often a smart investment that helps attract talent, improve employee satisfaction, support your sustainability goals, and even generate revenue if you open the stations to the public.

Maintenance is another important factor to consider. The cost of servicing EV charging stations varies depending on the number of chargers, ports, and type of charger. Many manufacturers offer maintenance plans to keep your stations running smoothly over time.

Preparing Your Business for the Future of Mobility

With stricter emissions regulations and bans on combustion engines on the horizon, investing in EV charging infrastructure is a smart move for businesses looking to stay ahead of the curve.

There’s no one-size-fits-all solution for EV charging. The best option for your workplace depends on your location, needs, and long-term goals.
