Running a business today means thinking about the future, and for a lot of us, that future includes electric vehicles. Maybe your team is starting to drive EVs, maybe your customers keep asking whether you offer charging, or maybe you just bought your first electric car and want to plug in at the end of the day without hunting for a public station. Whatever brought you here, installing commercial EV charging solutions is one of those decisions that looks simple on the surface and gets more layered the closer you look.
At Karisma Electric, we’ve installed EV chargers at homes, offices, retail spaces, and multi-tenant properties throughout the Denver area. As a trusted Denver area electrician, we’ve learned that a smooth installation almost always comes down to what you figure out before the equipment ever shows up. Here’s what I’d want any business owner or homeowner to think through first.
Start With Your Electrical Panel
Your panel is the foundation of the whole project. Before you fall in love with a specific charger, you need to know what your electrical service panel capacity can actually handle.
A licensed electrician will run a load calculation to see how much spare capacity your panel has. In older homes and commercial buildings, there’s often less room to work with than owners expect. That doesn’t mean you can’t install a charger. It just means you might need breaker panel upgrades, a subpanel, or a load management system that balances your charger against everything else drawing power. Knowing this upfront saves you from the classic mistake of buying equipment your building can’t support.
Choose the Right Charging Level
The two options most people weigh are Level 1 and Level 2, as detailed in our guide to understanding electric vehicle chargers. Level 1 uses a standard 120-volt outlet and adds only a few miles of range per hour, which is fine if you drive short distances and have all night to charge. For most business owners and daily drivers, Level 2 is the practical choice. It runs on 240 volts, delivers 25 to 40 miles of range per hour, and turns overnight charging into a genuine convenience rather than a slow crawl.
Level 2 chargers range from 16 to 80 amps, and the right size depends on your vehicle, your driving habits, and your electrical capacity. A commercial property serving multiple vehicles will need a very different setup than a single-family home.
Hardwired or Plug-In
You’ll also decide whether to hardwire the charger or install it with a NEMA 14-50 or 6-50 outlet. Hardwired units tend to be more reliable for high-amperage use and cleaner-looking on the wall. Plug-in installations offer flexibility, especially if you might move or upgrade the charger later. Neither is wrong. It really comes down to your goals for the space.
Think Through the Location
Where the charger lives matters more than most people realize. Shorter wire runs between your electrical panel and the parking area cut down on labor and material costs, sometimes significantly. If the panel sits far from where the vehicles park, expect a higher install price.
Outdoor installations need weather-rated enclosures, typically NEMA 3 or higher, and mounting heights that keep the equipment safe from vehicles, weather, and everyday wear. Indoor installations in garages or parking structures are usually simpler but still need proper ventilation and clearances.
For commercial spaces, consider foot traffic, ADA accessibility, lighting for nighttime use, and whether you want cable management to keep the area tidy.
Permits, Codes, and Inspections
EV charger installations almost always require a permit and an inspection from your local building department. This isn’t just paperwork. Codes exist to protect your property and anyone using the charger. Working with a licensed electrical contractor who handles the permitting process for you removes a real headache and keeps everything above board.
Plan for What’s Next
If you’re a business owner, think a step or two ahead. Are you installing one charger now but expecting to add more later? Running conduit and sizing your electrical service for future expansion during the initial install is far cheaper than tearing things back up in two years. The best EV projects I’ve seen were designed with growth in mind from day one.
Frequently Asked Questions
How long does a typical EV charger installation take?
Most residential Level 2 installations are completed in a single day. Commercial installations vary widely based on scope, panel upgrades, trenching, and the number of chargers, but a straightforward single-charger install often wraps up in one to two days.
Do I need a permit to install an EV charger?
In nearly every Colorado municipality, yes. A permit and a follow-up inspection are standard requirements, and a licensed electrician will handle this process on your behalf.
Can I install an EV charger myself?
It’s not recommended. EV chargers involve high-amperage 240-volt circuits, and mistakes can lead to fire hazards, voided warranties, and failed inspections. There are many reasons why you shouldn’t DIY electrical work; a licensed electrician ensures the job is safe, compliant, and covered.
Will installing an EV charger affect my electric bill?
Yes, though usually less than most people expect. Home charging is typically far cheaper per mile than gasoline, and many utility providers in Colorado offer time-of-use rates that lower costs further when you charge overnight.
Do I need to upgrade my electrical panel before installing a Level 2 charger?
Sometimes, but not always. It depends on your panel’s current capacity and how much of it is already in use. A load calculation will tell you what’s needed. In some cases, a smart load management system can eliminate the need for an upgrade entirely.
What kind of charger is best for a commercial property?
That depends on how many vehicles you’re serving, whether the chargers are for employees, customers, or both, and your goals for future expansion. A commercial electrician can walk you through options, including networked chargers that offer usage tracking and payment features.
