5 Signs Your Workplace EV Charging Is About to Become a Problem

There's a window, usually about six months to a year, between 'we installed some chargers' and 'charging has become a recurring problem.' The window is useful because it gives you time to put a real system in place before the chaos fully arrives. The tricky part is recognizing you're in it.

Here are the five warning signs, in rough chronological order. If you're seeing even two of them, the inflection point is closer than you think.

Sign 1: Your EV Count Is Approaching Your Stall Count

This is the most reliable leading indicator. When you have 4 EVs and 6 stalls, it's fine. Nobody waits, nobody conflicts, the honor system holds. When you have 8 EVs and 6 stalls, the math changes: on any given day, 2 drivers won't be able to charge. That's when informal coordination starts to matter.

EV adoption at U.S. companies has been growing at roughly 30% year-over-year among early-adopter workplaces. If you installed 6 stalls for 4 drivers, you've probably already hit parity or will within a year. The time to prepare is before you hit parity, not after.

Sign 2: The First "Hey, Is That Stall Free?" Slack Message

You'll remember this one. It's usually innocuous, friendly even. Someone posts in general or #office-stuff: 'Hey, does anyone know if the charging spots are free right now?' It gets a few responses, someone checks on their way to a meeting, it resolves.

The reason this is a warning sign isn't the message itself. It's what it represents. Someone needed to charge, didn't know if a stall was available, and had no way to find out except to ask publicly. That's a visibility gap. Visibility gaps don't go away on their own; they grow as more people encounter them.

Sign 3: HR Hears About It

This one usually takes people by surprise. EV charging is a parking issue, right? Facilities territory? In practice, when charging access feels unfair, it becomes a people issue fast. The complaint isn't usually 'the charger was taken.' It's 'the same people always seem to get the chargers' or 'I asked Sarah if she was done and she didn't respond for two hours.'

Once HR is involved, the cost profile of the problem changes significantly. HR time is expensive, and the interpersonal dimension is hard to resolve without a systemic fix. If HR has heard about charging more than once, the informal system is failing structurally, not randomly.

Sign 4: Someone Makes a Spreadsheet

We've said it before and we'll say it again: the spreadsheet is not the solution; it's a symptom. When a spreadsheet appears, it means someone cared enough about the problem to invest real time in fixing it. That's good! But it also means the situation had already deteriorated enough that informal coordination was visibly failing.

The spreadsheet phase typically lasts 2–4 months before it starts breaking down. Data goes stale, nobody updates check-outs, and the same problems return. By the time the spreadsheet is failing, the problem has been festering for 6 months or more. Get ahead of it.

Sign 5: A Non-EV Parks in a Charging Spot

This is the canary in the coal mine. When a non-EV driver takes a charging stall, because they were late, because the lot was full, because the signage was unclear, and an EV driver can't charge that day, you've crossed into territory where the problem affects people who can't self-solve it by being quicker on Slack.

It's rarely malicious. But the resolution is always awkward: someone has to track down the non-EV driver, ask them to move, and navigate the social dynamics of the conversation. Do that once and it's an incident. Do it three times and it's a policy failure waiting for an HR complaint.

What to Do When You See These Signs

The good news is that all five signs are early enough that a proactive response prevents the worst outcomes. A written charging policy (even a half-page document), combined with a real-time coordination tool, is enough to reset the dynamic before it hardens into resentment.

The companies that handle this well are the ones that respond to Sign 1 or Sign 2, not the ones that wait for Sign 5. At that point, you're managing a conflict rather than preventing one. The infrastructure is already there. The coordination layer is what's missing.
