Building Fleet EV Charging: Getting the Balance Right Between Plugs, Sites, and Location

As fleets move from pilot projects to scaled electric vehicle (EV) deployment, one of the most important infrastructure questions arises: how should you balance the number of plugs, the number of sites, and their geographic distribution?

It’s not a simple “more is better” equation. The choices you make will determine whether your charging strategy meets operational needs, keeps vehicles moving, and delivers return on investment.

Plugs: Capacity and Redundancy

When people talk about network size, the first metric that comes up is often the number of plugs. This makes sense: plugs equal capacity. More plugs mean more vehicles can charge simultaneously and reduce wait times.

As Evie Networks’ Paul Fox explained, “Overseas they’ve been measuring plugs for a long time because it gives you an idea of total market capacity. It’s also about redundancy – if you’ve only got one charger and it breaks, you’ve got nothing.”

For fleets, redundancy is critical. A single-point failure can disrupt deliveries, service schedules, or driver productivity. Having multiple plugs per site ensures continuity and reduces downtime risk.

Sites: Coverage and Access

While plugs measure capacity, sites measure coverage. A network with fewer, larger sites may have plenty of plugs, but if they’re not in the right places, they don’t help your fleet.

“Most people top-line talk about plugs,” Fox noted, “but it is good to look at sites as well, because that gives you an idea of coverage. For a fleet customer, they’re interested in both capacity and coverage. But at the moment, most are more interested in coverage – knowing you’ve got a site near them.”

For fleets with dispersed operations – local government, utilities, or regional service providers – spreading sites strategically may matter more than building mega-hubs. Coverage is also valuable where vehicles are garaged at the driver’s home.

Geographic Location: The Deciding Factor

Neither plugs nor sites deliver value if they aren’t in the right place. For consumer drivers, proximity to home is key. For fleets, location needs to align with vehicle movement patterns:

• Where do your vehicles park overnight?
• Where do they start and finish routes?
• Are there natural dwell points during the day (near depots, retail stops, or logistics hubs)?

Fox highlighted how even small details matter: “One fleet told me their drivers liked our charger at Hungry Jack’s. They could grab a coffee or walk back to the office to pick up dispatch while the van charged.”

Location is about more than geography – it’s about integrating charging into daily operations.

Finding the Balance

For Fleet Managers, the right balance between plugs, sites, and geography depends on fleet profile:

• Urban delivery fleets may prioritise multiple plugs at fewer sites near industrial hubs.
• Regional service fleets may prefer more sites with fewer plugs each, ensuring coverage across wide areas.
• Mixed fleets (cars, vans, utes) may need a hybrid approach – strong metro hubs plus strategic regional sites.

The key is to avoid over-investing in one dimension at the expense of the others. A dozen plugs in the wrong suburb won’t solve operational challenges. Likewise, a network of single-plug sites may look good on paper but fail under load.

Lessons from Public Networks

Public charging networks face the same challenge. Tesla has focused on larger sites with many plugs, while Evie Networks has built broader coverage with more sites. Both strategies have trade-offs, and both show why fleets need to model their specific use cases rather than copying one approach.

Practical Next Steps for Fleet Managers

1. Map vehicle movements – use telematics or driver logs to understand where charging is most needed.
2. Prioritise redundancy – ensure key sites have multiple plugs to avoid downtime.
3. Plan for growth – build sites that can be scaled as your EV fleet expands.
4. Think about dwell time – co-locate chargers where drivers can safely and productively spend 20–40 minutes.
5. Engage partners early – energy providers, landlords, and charging operators can help optimise location and scale.

The transition to EVs isn’t just about vehicles – it’s about building the right charging backbone. For Fleet Managers, success will come from balancing plugs, sites, and location in a way that fits operational patterns.

As Paul Fox’s insights highlight, capacity matters, coverage matters, but geography decides whether charging works for your fleet or leaves vehicles stranded.

  How an electric van is powering Big Group Hug’s mission
  For many fleet operators, electric vans are still being trialled, tested and debated. For Melbourne-based charity Big Group Hug, an electric van is already part of the daily workload — moving essential goods, supporting vulnerable families and quietly proving where EVs work best. Big Group Hug is a volunteer-driven, not-for-profit organisation supporting disadvantaged Victorian families by

  Medium SUVs Surge as FBT Exemption Reshapes EV Uptake
  The Fringe Benefits Tax (FBT) exemption for eligible electric vehicles has had a measurable impact on Australia’s EV market — but not evenly across all segments. According to Kristian Handberg, General Manager – Future Business and Origination at JET Charge, the strongest uplift has occurred in the medium SUV category, where salary packaging dynamics and

  Why waiting for “better batteries” may cost fleets more in the long run
  Across Australia’s fleet sector, one hesitation keeps resurfacing: we’ll wait until the batteries get better. On the surface, it sounds sensible. Battery costs are falling, technology is improving and vehicle choice is expanding. Why lock in now? That question was tackled head-on during a late-2025 webinar hosted by the Australasian Fleet Management Association and sponsored by JET Charge. The

  Smaller batteries, smarter decisions: why electric truck fleets are rethinking range
  As electric trucks move from trial phase to day-to-day operations, fleet buyers are starting to challenge one of the earliest assumptions of electrification: that more battery is always better. According to Michael Bridge, Director – National Fleet at Volvo Group Australia, the conversation with fleet customers has shifted noticeably over the past two years. “We’re seeing
