Workplace charging usually starts small: one or two staff ask to plug in. A year later, six people want the same thing, and the two chargers installed without a plan are at their limit.
Successful workplace EV charging NZ businesses can rely on starts with planning for the demand you will have in a few years, not just today. That means checking electrical capacity, deciding who can use the chargers and choosing a system that expands without starting again.
Staff who rent, live in apartments or park on the street often rely on public chargers. Charging at work gives them a reliable option while their car is parked anyway.
For HR teams, employee EV charging is a practical benefit that helps attract and keep staff. For sustainability teams, it provides usage data to report against. For commercial property managers, charging is fast becoming something tenants expect, and office EV charging solutions can make a building more attractive to lease.
Most workplace charging stations use AC chargers, commonly 7 kW single-phase or up to 22 kW three-phase. Because cars are parked most of the day, high speeds are rarely needed. A 7 kW charger adds around 40 km of range per hour for many vehicles, which covers most daily commutes quickly.
Users start sessions with an app or RFID card, and software controls access and pricing.
DC fast chargers generally suit fleet EV charging with quick turnarounds or public sites better than staff who park all day.
Before you request quotes, work through these points:
Demand: Survey staff about current EVs and plans to buy one in the next few years.
Users: Decide whether chargers are for staff, fleet vehicles, visitors, tenants or a mix.
Cost to users: Decide whether charging is free, subsidised or paid. Free staff charging may have tax implications, so check with your accountant.
Etiquette: Set a clear rule on moving vehicles once charged.
Property: Tenants need landlord approval and should agree who owns the chargers when the lease ends. In multi-tenant buildings, property managers should plan how charging is shared and billed to each tenant.
Commercial EV charging at a workplace has one challenge that overnight fleet charging often avoids. Staff charge during business hours, when the building is already using the most power for lighting, heating, cooling and equipment.
A site assessment should look at:
Uncontrolled charging at the building’s busiest time can raise peak demand charges. An EV charging feasibility study from EVSE uses your site’s real load data to show how many chargers it can support and what each stage will cost.
All fixed chargers must be installed by a licensed electrician and certified as compliant with New Zealand electrical requirements.
Smart charging lets more chargers share a limited supply. Load management monitors the building’s total demand, reduces charging power when the site is busy and increases it again when capacity frees up.
A car parked for eight hours still leaves with plenty of range, and the business can often add chargers without a supply upgrade.
Charge management software also handles user access, pricing, session history and sustainability reporting. EVSE sets this up during commissioning and monitors connected chargers so faults are picked up early.
If your staff survey shows four EV drivers now and twelve expected later, design for twelve and install for four:
Run conduits or cable capacity to future bays during the first installation.
Choose OCPP-compliant chargers, so you are not tied to one software platform.
Set load management limits that can be adjusted as chargers are added.
Budget for maintenance, so a fault does not leave chargers out of use for weeks.
This avoids reopening car park surfaces later and lets your workplace EV infrastructure grow with EV adoption.
Buying EV chargers for businesses online and asking a general electrician to install them can look cheaper at first. The problems usually appear later: no load management, no way to control who charges, no usage data and no clear contact when a unit stops working.
EVSE manages the complete process:

The cost depends on the number of chargers, their power, cable runs, switchboard work, any supply upgrade and software fees. It is also worth checking EECA for current co-funding rounds.
Start with current EV drivers and expected growth from a staff survey. Because cars are parked for long periods, one charger can often serve more than one vehicle a day if staff move cars once charged.
Yes. Employee EV charging works best under a clear policy covering access, cost and etiquette. Software controls who uses each charger and whether a fee applies.
Not always. Many sites can add chargers using existing capacity with load management. Upgrades are more likely when you plan many chargers or the building already runs close to its supply limit.
