What Fleet Operators Should Know Before Adding On-Site EV Charging
When fleets go electric, most of the planning process focuses on the electric vehicle range, cost, and availability. The charging infrastructure is an afterthought, but it shouldn’t be. In practice, it’s usually the harder part of the project, and getting it wrong is what actually causes headaches down the road. Here's what's worth thinking through before you commit.
How to Assess Your Fleet's EV Charging Needs
Start by analyzing how your fleet actually operates:
How many vehicles need charging?
What are their daily routes and mileage?
How much downtime do they realistically have?
A fleet that returns to the shop every night and sits for eight hours has different charging needs from one that needs a quick midday top-up between routes. By considering your fleet's real duty cycles, you can strategize EV infrastructure to match that demand. This prevents fleet operators from investing in more EV chargers than needed, or worse, not enough EV chargers to meet capacity.
Electrical Capacity and Utility Connection for Fleet EV Charging
One thing many don’t consider when installing on-site EV infrastructure is grid connection and capacity. Charging a fleet of vehicles, especially if several charge at once, adds a real amount of load to your site's electrical service. Depending on your current capacity, that might mean a utility service upgrade. A utility service upgrade can take a lot longer to arrange than the charging equipment itself takes to install.
To avoid this: talk to your utility early, well before you're picking out chargers. Finding out partway through a project that your site needs a service upgrade can set the whole timeline back.
Level 2 vs. DC Fast Charging: Choosing the Right Equipment for Your Fleet
Not every fleet needs fast charging everywhere. Level 2 charging is slower but far less expensive to install, and it works well for vehicles that have several hours to charge, like a depot fleet charging overnight. DC fast charging gets vehicles back on the road much quicker, but it costs more to install and puts more strain on your electrical system.
The right approach is usually a mix based on how your vehicles actually operate:
Level 2 for vehicles with long dwell times
DC fast charging reserved for vehicles that need a quick turnaround
Matching equipment to real duty cycles, rather than defaulting to the fastest option everywhere, keeps costs as reasonable as possible, without sacrificing capacity or performance.
How Fleet EV Charging Affects Demand Charges and Peak Load
Commercial electricity bills in Ontario aren't just based on how much power you use, they're also based on how much power you draw at your highest moment. If your interval meter shows a spike from several vehicles charging at the same time, that peak can set your demand charge for the entire billing period, even if it only happened once in that billing period.
This means the way you schedule charging matters just as much as the charging equipment you install. Staggering charging times, or using load management software to spread out when vehicles draw power, can reduce your exposure to demand charges. Letting the whole fleet plug in at once may seem efficient, but if you can stagger charging to avoid creating a large spike in electricity demand, that’s the better approach.
Planning EV Charging Infrastructure for Future Fleet Growth
If you’re planning to grow your fleet over time, it's worth building in more capacity than your current fleet needs. It’s actually more affordable to future-proof your investment than focus only on your current capacity, then adding conduit runs and electrical panel capacity later. A charging setup that's sized exactly to today's fleet can turn into a bottleneck the moment you add a few more vehicles, and expanding it after the fact usually costs more and causes more disruption than building in some headroom from the start.
VCT Group Helps Fleets Protect Their Investment
We conduct site assessments to understand your electrical capacity, your fleet's actual charging needs, and whether renewable energy solutions like solar makes sense alongside it. We specialize in creating future-proof EV infrastructure designs that meet your current capacity needs, accommodate future charging demands, and maximize your investment.
As a fleet operator, your priority is keeping your fleet moving. Understanding the demands of a new EV charging station and its impact on the grid isn’t always straightforward. That’s where we come in. We help you navigate grid demand, strategic electricity use, and the infrastructure needed to keep your fleet charging reliably.
