Practical guide

Workplace EV charging: a practical planning guide

Plan employee, visitor and fleet charging around demand, dwell time, site power, access, billing, maintenance and EU building requirements.

Workplace charging succeeds when it serves a defined group of drivers. “Install some chargers” is not a service definition.

Separate employee, fleet and visitor needs. They have different arrival times, dwell times and consequences when charging fails.

Define who the chargers serve

Employees often park for many hours. Lower AC power can still replace their commute energy. Visitors may stay for one meeting and value a simple payment or free short session. Fleet vehicles may have a fixed dispatch time and a non-negotiable energy target.

Write one sentence for each group. For example: “Eight employee cars can each recover an average commute during a normal workday.” That can be tested. “Provide EV charging” cannot.

Decide whether the site is private, semi-public or publicly accessible. This affects access, payment, signage and potentially the rules that apply.

Measure demand in energy and time

Survey likely users, but do not equate stated interest with daily simultaneous use. Ask distance, arrival, departure and existing home-charging access.

Then estimate energy. A 50 km round trip at 18 kWh per 100 km uses about 9 kWh in the battery. Charging losses raise wall energy above that.

Ten such users need roughly 100 kWh from the wall, depending on efficiency. If cars remain for eight hours, the average site power needed is far lower than ten times 11 kW.

Test a normal day and a difficult day. Fleet routes, winter consumption and Monday demand after a weekend may change the peak.

Assess the site supply

Commission an electrical assessment. It should cover the connection, actual load profile, distribution, cable route, protection, earthing, environmental exposure and future building projects.

Set an EV power budget that does not compromise critical loads. Dynamic control can vary charging within that budget as other demand changes.

Do not promise every port its full rating simultaneously unless the electrical design supports that promise. Displayed charger ratings and available site power are different numbers.

Choose ports and power together

More lower-power ports can suit long employee dwell times. Fewer higher-power units may suit pool vehicles that return between shifts. A mixed design can separate fleet priorities from employee access.

Consider whether cables are tethered or supplied by drivers. A tethered cable is convenient but adds an exposed item to inspect and replace. An untethered socket keeps the unit tidier but expects users to carry a compatible cable.

Place accessible charging bays with the same care as other accessible parking. Protect chargers from vehicle impact without creating cable or wheelchair obstacles.

Decide access and fairness

A workplace needs rules before the first queue. Options include assigned fleet ports, employee booking, time limits, rotation after completion or open access until capacity is reached.

Avoid rules that require unsafe rushing or constant car movement. A notification when charging finishes can help, but not every employee can leave a production line or meeting immediately.

Publish what happens when demand exceeds capacity. A fair waiting list or priority rule is better than informal access captured by the earliest arrival.

Pilot the policy as well as the hardware

Start with a defined user group and collect session data. Review unmet requests, dwell time, energy and faults before expanding. The pilot should answer operational questions, not only prove that a charger turns on.

Set the price and tax treatment

Charging can be free, subsidized, sold at cost or priced by an operator. The choice may have tax, employment and consumer-law effects. Get local professional advice.

Metering must support the chosen policy. Decide how fixed service fees, idle fees, guest charging and failed sessions are handled. State prices before a user starts where required.

Protect personal data. A billing platform does not need unlimited access to employee movement. Define retention, administrators and the process when someone leaves the company.

Plan maintenance and support

Name the service owner. Drivers need one route for faults, access problems and billing questions. Facilities staff need isolation instructions and installer records.

Specify uptime monitoring, inspection, cleaning, cable replacement and software support. Keep emergency access and fire routes clear. Test what happens after an internet or backend outage.

A charger that is powered but cannot authorize employees is still unavailable.

Check EU and national building rules

Directive (EU) 2024/1275 includes charging infrastructure duties for defined non-residential buildings. Article 14 covers new buildings, major renovations and existing buildings above parking thresholds, with dates, conditions and possible derogations.

These are duties for Member States to implement. Check current national law for the property type, number of spaces, renovation scope and deadlines. Also check planning, grid, accessibility, fire and workplace requirements.

Do not copy a threshold from an article into a construction brief without local verification.

Leave a clean expansion path

Provide cable routes, board space, network capacity and a controller that can add ports. Record configuration and ownership of administrator accounts.

Review the service using energy delivered, successful sessions, unmet demand and support incidents. Add capacity where the data shows a real constraint.

The best workplace charging plan begins with people and schedules. Hardware comes after the service is clear.

Frequently asked questions

How many workplace chargers should a business install?

Start from users, daily energy and dwell time rather than one charger-per-EV. Test growth scenarios and leave an expansion path.

Do workplace chargers all need 22 kW?

No. Cars parked for a workday may meet their energy need at lower shared power. Fleet turnaround or short visitor stays can require another service level.

Should employees pay for charging?

That is a business, tax and local-law decision. Whatever the policy, state it clearly and use metering and access controls that can support it.

Are EU workplace charging requirements identical in every country?

No. EU directives set requirements for Member States, while implementation, exemptions, dates and permitting need checking under current national rules.
