Installing EV chargers at the workplace is the easy part. Call the electrician, mount the wallboxes, done. What comes next is the real challenge — and it's exactly where most companies fail.
Not dramatically. Not with a big bang. But gradually. Through daily friction that builds up over months, until "EV charging" has become synonymous with chaos in the office.
It doesn't have to be that way. Most mistakes in charger management are predictable — and preventable. Here are the seven most common ones.
Mistake 1: Installing chargers without a management plan
The most common mistake is also the most fundamental: buying hardware and assuming the rest will sort itself out.
In the early phase, that's actually true. When three EVs share four chargers, you don't need a system. But EV adoption grows exponentially, not linearly. A company that had three EVs in 2024 will have ten by 2026. That's not a worst case — that's the normal trajectory.
By the time you have more cars than chargers and still no management concept, you're dealing with a problem that's hard to solve retroactively. Because by then, informal habits have formed. Certain people consider "their" station a permanent spot. Any change feels like a loss.
Better: Introduce a simple system from day one — even if it feels like overkill at first. Five minutes of setup time today saves months of conflict management later.
Mistake 2: Trusting goodwill instead of structure
"Our people are adults, they'll figure it out." You hear this at almost every company. And at almost every company, it turns out not to be true.
Not because employees are unreasonable. But because different people have different ideas about fairness — and without clear rules, every one of those ideas is equally valid.
The early bird who grabs the station at 7 AM thinks first-come-first-served is fair. The colleague who arrives at 9 and never finds a free charger thinks otherwise. Both are right — from their perspective. Without a binding framework, there's no common standard.
The typical escalation path: silent frustration → passive-aggressive messages in the team chat → open conflict → HR gets involved → the issue lands on the CEO's desk, who really has other things to worry about.
Better: Clear, simple rules enforced by a system. Maximum charging time, booking limits, automatic reminders. Not because you don't trust your employees — but because you're removing the burden of negotiating fairness on their own.
Mistake 3: Treating WhatsApp groups and spreadsheets as a permanent solution
Nearly every company goes through the same phase: someone creates a WhatsApp group or a shared spreadsheet to coordinate the chargers. It works for about two weeks.
Then the inevitable happens. Not everyone is in the group. The spreadsheet doesn't get updated. Two people book the same slot because they had the file open at the same time. Someone writes "Done charging!" in the chat — but nobody reacts because they're all in meetings.
The problem isn't the idea. The idea — transparency and communication — is exactly right. The problem is the medium. WhatsApp and Excel aren't built for real-time resource management. They don't have waitlists, automatic notifications, live status updates, or rule enforcement.
Using them as a stopgap is fine. Running them as a permanent solution is a mistake.
Better: A purpose-built tool that combines the right idea with the right medium. Live status, bookings, reminders, waitlists — all in one place, automated and in real time.
Mistake 4: Collecting zero data on actual usage
Question for every facility manager: What's the actual utilization rate of your EV chargers?
Nine times out of ten, the answer is: "Feels pretty high." But feelings aren't data. And without data, every decision about your charging infrastructure is a guessing game.
This affects several questions at once: Do you need more chargers — or are the existing ones just being used inefficiently? Which days have the highest demand? Are there times when stations sit idle? What's the average wait time? How many employees use the chargers regularly versus occasionally?
Without this information, companies either invest too much (three new chargers when better management would have been enough) or too little (employees wait 45 minutes every day, but nobody notices because no one complains).
This becomes especially relevant as regulations tighten. In the EU, the revised Energy Performance of Buildings Directive (EPBD) will require significantly more chargers in commercial buildings by 2027. Knowing how your current infrastructure is actually performing is invaluable for planning ahead.
Better: Use a system that captures usage data automatically. Utilization rates, peak hours, average session length, waitlist depth. Data you don't have to collect manually — it's a natural byproduct of a good booking system.
Mistake 5: Hiding the chargers in the back corner of the parking garage
Sounds like a minor detail, but it has a surprisingly large impact on perception.
When EV chargers are tucked away in the farthest corner of the garage — poorly lit, hard to find, no signage — you're sending a message: this isn't a priority for us.
That's especially counterproductive if the company uses EV charging in its employer branding. "We offer on-site charging" sounds great — until the new hire spends ten minutes wandering around the basement on their first day trying to find it.
Location also has a direct effect on rotation willingness. If moving your car after charging means a five-minute walk back to the office, motivation to free up the spot quickly drops. That worsens the utilization problem.
Better: Position chargers visibly and accessibly. Clear signage in the garage. Ideally near the entrance — it signals that you value the benefit and reduces the friction for quick turnovers.
Mistake 6: Thinking about scaling too late
Most companies install EV chargers reactively: when the first employees ask, one or two wallboxes go up. When complaints increase, two more are added. Always one step behind demand.
The problem: charging infrastructure doesn't scale overnight. The building's electrical capacity needs to be assessed. A new sub-panel might be necessary. Permits, quotes, installation appointments — this takes months, not days.
Companies that only react once capacity is already exceeded face a problem they can't solve quickly. The result: months of insufficient charging infrastructure, rising frustration, and the reputation of a company that can't manage its own benefits.
On top of that, regulatory requirements are tightening. The EU's building directive will demand significantly more chargers in existing commercial buildings from 2027 onward. Companies that plan proactively now will save time and money later.
Better: Plan ahead. Have the building's electrical capacity assessed early. When the next renovation comes around, install conduit and cabling for more chargers than you currently need. And use usage data to forecast demand based on facts, not hunches.
Mistake 7: Making it someone else's problem
EV charging is a cross-functional topic. The hardware falls under facility management. Tax treatment goes to finance. Employee communications belong to HR. Whether it's a compliance exercise or a real benefit is a strategic decision.
When the topic sits solely with facility management, it gets treated as a technical issue: hardware works, box checked, done. The opportunity to create a genuine employee benefit gets lost.
When it sits solely with HR, the technical expertise is missing. When it goes to IT, it becomes a project that takes months and produces a custom system nobody wants to maintain.
Better: Assign a single owner who oversees the topic holistically — and choose a tool that's simple enough to set up without IT involvement or external consultants. Configuration in minutes, not months. Administration in the browser, not in server infrastructure.
The common thread
All seven mistakes share the same root cause: treating workplace charging as a pure infrastructure topic. Install hardware and move on.
But EV chargers at the workplace aren't an infrastructure topic. They're an organizational one. The hardware is the prerequisite. The organization is what makes the difference between a benefit and a problem.
That organization doesn't have to be complex. It doesn't have to be expensive. And it definitely doesn't have to be an IT project. What it does have to be: thoughtful, transparent, and automated.
A good charging system does three things: it gives employees a fair, transparent way to use the chargers. It gives facility management the data it needs for good decisions. And it runs in the background without anyone having to actively manage it.
That's all it takes. But anything less isn't enough.
Checklist: Does this apply to you?
If you answer yes to at least three of the following, it's worth taking a closer look at your charger management:
You have more EVs than charging stations at your location. Chargers are managed through informal arrangements, chat groups, or spreadsheets. You don't know the actual utilization rate of your stations. There have been complaints or conflicts around charging. Employees block chargers longer than necessary. You plan to increase the number of chargers in the next 12 months. Your company has multiple locations with EV chargers.
If that sounds familiar, it's not a reason to panic — but it is a good time to act. The sooner you introduce a system, the fewer legacy issues you'll have to clean up later.
