When planning a charging network, operators face a basic choice: concentrate chargers in a few large hubs, or spread single chargers across many locations. Both can work. The right mix depends on where demand is, how much power is available and how you plan to run the network.
The case for hubs
- Reliability for drivers: if one charger is busy or faulty, others are available. Drivers learn they can always charge there.
- Shared infrastructure: one grid connection, transformer and set of civil works serves many chargers, lowering cost per charger.
- Power sharing: dynamic power sharing uses the site's power efficiently across many guns.
- Easier operations: maintenance teams visit one site instead of many.
- Amenities: larger sites justify canopies, seating, food and restrooms.
The case for single chargers
- Coverage: a presence in more places, which helps drivers trust the network.
- Lower risk per site: small investments in many places, testing demand before scaling.
- Fits limited power: many sites can host one charger without a grid upgrade.
- Destination charging: one or two chargers suit hotels, restaurants and offices.
The weaknesses
Hubs need high upfront investment, more grid capacity and longer approvals, and they depend on picking the right location. Single chargers are more exposed to faults and queues: if the only charger is busy or down, the driver has nowhere to go. They are also harder to maintain across many locations.
A practical approach
- Start with a hub at your strongest location: a highway corridor, city centre or fleet hub.
- Add single chargers at destinations to extend coverage.
- Upgrade single sites to small hubs where utilisation is consistently high.
- Plan cable routes and power so busy single sites can grow without rework.
Questions to decide the mix
- Where do drivers need to charge, and how long do they stay?
- Where is grid power already available?
- How fast can you get approvals and connections?
- Can your team maintain many scattered sites quickly?
