The station layer is where a sharing or rental programme spends money before it earns any. A vehicle purchase scales linearly with fleet size, but the station network does not: a dock deployment carries power, networking and weatherproofing to every single parking position, and that bill lands before the first ride. Operators who treat the station as an accessory to the vehicle order routinely discover the infrastructure cost after the fleet is already committed.
This guide sets out the architectural choice that decides that cost, the capacity arithmetic that sizes it, and the procurement items that most often go wrong. It is written for the buyer defining the station layer, not for the rider using it.
The Station Is a Separate Purchase From the Vehicle
The most common planning error is assuming the vehicle order defines the station. It does not. A vehicle spec answers what the rider experiences; a station spec answers how many vehicles can be serviced per hour, how much power the site needs, and who owns the asset when the programme ends. Those are procurement questions with their own vendors, own certification path and own failure modes.
Three station architectures cover almost every programme. Each one moves the cost to a different place, and the right choice follows from the deployment pattern rather than from a preference for newer hardware.
Architecture 1: Individual Docks
A dock is a physical parking position with a captive cable or power rail, and often a locking mechanism and a comms link. Its advantage is that charging and parking are the same action, so the vehicle cannot be parked without being charged. Its cost structure is the problem: power, networking and weatherproofing have to be carried to every position.
That makes the per-position civil and electrical cost the dominant line item on a large network, and it does not fall with volume the way vehicle cost does. Docks suit dense urban grids where positions are fixed, visible and powered from existing street furniture, and where the operator needs the enforcement value of a fixed corral.
Architecture 2: Central Charging Cabinets
A cabinet decouples charging from parking. Vehicles park wherever the permit allows, and packs are charged in a secure indoor bank. One cabinet serves many vehicles, so the electrical work is done once instead of once per position.
The trade-off is labour. Someone has to carry packs between the cabinet and the vehicles, so cabinets only pay off where swap is fast enough to fit a shift change. Depot-level energy planning, including how much a full fleet pulls from the site each night, is worked through in our fleet charging and depot capacity guide. This is why the pack-level design matters more than the cabinet itself: a tool-free latch mechanism that lets depot staff swap batteries without tools is what makes the whole architecture work. At that speed a two-person depot team can move a substantial number of packs per hour with no vehicle downtime at all.
Architecture 3: Battery Swap Pool
Rather than charging a pack per vehicle, the fleet runs more packs than vehicles and rotates them. The spare packs are not dead capital, they are shift capacity: a fleet with a spare pack per vehicle carries substantially more usable energy than the same fleet with one pack each, at a fraction of the cost of buying extra vehicles.
Swap pools pair naturally with fast chargers, because a pack that is not in use can charge slowly and gently at low amperage without anyone waiting on it. Cells degrade with charge rate, so a swap pool that charges at 2–5A overnight gets materially more cycles from the same cells than a fleet fast-charging at 8–10A under time pressure. Charger amperage, connector types and certification are covered in detail in our smart charger specification guide. Cell count is the fleet's replacement schedule, and buying cycles back through slower charging is one of the few genuinely free wins in fleet planning.
Capacity Math: Size the Station From the Duty Cycle
Station capacity is arithmetic once the fleet's daily energy need is known. If pack sizing is still open, start with our battery pack selection guide., and the daily energy need comes from the pack. On this platform a 36V 10Ah pack stores 0.36 kWh, a 48V 15Ah pack stores 0.72 kWh and a 48V 20Ah pack stores 0.96 kWh. Multiply by the number of vehicles and by the number of charge cycles per day and the site's daily energy demand falls out immediately.
The number that usually gets missed is not energy, it is power. A standard 5A charger draws roughly 300W from the wall. Twenty of them running at the same time pull about 6 kW from one phase, which is a different electrical conversation from a 20-vehicle order of small traction batteries. Staggered into two waves overnight, the same fleet needs only about 3 kW of dedicated capacity. Wave scheduling is not an optimisation to add later; it is a design decision that changes whether the site needs an electrical upgrade at all.
| Fleet Size | Pack | Daily Energy | Chargers at 5A | Peak Load (single wave) |
|---|---|---|---|---|
| 20 vehicles | 48V 15Ah (0.72 kWh) | 14.4 kWh | 20 | ~6.0 kW |
| 20 vehicles | 48V 20Ah (0.96 kWh) | 19.2 kWh | 20 | ~6.0 kW |
| 50 vehicles | 48V 15Ah (0.72 kWh) | 36.0 kWh | 50 | ~15.0 kW |
| 50 vehicles | 48V 20Ah (0.96 kWh) | 48.0 kWh | 50 | ~15.0 kW |
Read the table as a two-sided constraint. Energy determines the electricity bill and the number of packs the site turns over each night. Power determines the size of the supply, the sub-panel count and whether the operator is booking an electrician or a civil contractor. Both scale linearly with fleet size, which is precisely why the architecture choice has to be made before the fleet size is finalised, not after.
The Connector Standard Is the Decision That Ages Worst
Station hardware outlives vehicle generations. A dock installed for one scooter model will still be standing when that model is retired, so the connector and rail interface is effectively a multi-year commitment made on the basis of a single batch of vehicles.
Two rules prevent the worst outcome. First, standardise the interface across the programme rather than per model, so a mixed fleet of scooters, e-bikes and trikes can share the same station layer. Second, buy station hardware from a supplier who will still be supplying the mating half of the connector in three years. Vehicle platforms change faster than connectors, and an orphaned connector standard strands every dock on the site.
Where the fleet mixes platform types, the vehicle side of this decision is the docking-rail compatibility of each tier. On the shared-mobility build tiers, docking-rail compatibility, per-cell battery telemetry and tamper alarm are configured at the top tier, while entry tier vehicles carry basic GPS and mechanical brakes. Planning a station network means planning which vehicles are allowed to occupy which positions, and that mapping should be fixed in the order documents rather than discovered in the field.
What the Station Costs, Line by Line
Station cost is not one number. Split it into four groups before comparing suppliers, because quotes that look competitive on the hardware line can lose on the others.
- Vehicles and station hardware. The vehicle FOB band on the city scooter platform runs $290–350 per unit, and station hardware is quoted separately as a project line. Fixed stations, rails, cables and locking hardware price per position, not per vehicle.
- Civil and electrical. Power distribution, sub-panels, weatherproofing, ground works and data connectivity. This is the group that surprises operators, because it scales with positions rather than with fleet value and is invisible in a vehicle quotation.
- Installation and commissioning. Physical install, commissioning of the comms link and firmware pairing between station and vehicle. Budget it per site, and expect the first site to cost more than the second.
- Service and spares. Station hardware takes weather and abuse continuously. A service contract covering station and vehicle maintenance is part of the procurement scope on campus and compound programmes, and it is better defined at order time than negotiated after a failure.
The architecture decision moves cost between these groups. Docks shift cost into civil and electrical work. Cabinets and swap pools shift cost into packs and labour, and reduce the powered-position count. Neither is cheaper in the abstract; one or the other is cheaper for a particular deployment pattern, permit regime and labour cost.
Which Architecture Fits Which Programme
Deployment pattern, not hardware preference, decides the answer. Three patterns cover most programmes.
Dockless City Fleets
Permit-driven before it is fleet-driven. The city sets governed speed, lighting, geofencing and telemetry requirements, and the operator bids on volume and service area. Station infrastructure is often deliberately minimal: the vehicles charge from swappable packs carried back to a central cabinet, and charging infrastructure cost per dock is avoided almost entirely because there are no docks. The whole station strategy becomes depot capacity plus a pack pool, which is why swappable architecture dominates this pattern. The wider economics of this model are set out in our shared scooter fleet guide, and where the same vehicles are used for commercial work rather than rides, see the delivery scooter fleet guide.
Docked Campus and Compound Programmes
Universities, campuses and gated communities trade vandalism exposure for control. Here the station is the product: docking rails, a fixed station network and per-vehicle telemetry define the programme, and riders use a shared battery pool with a service contract covering both station and vehicle maintenance. Spec is defined by the station and geofence layout first, and the vehicle follows. Resort and hospitality programmes with the same fixed-station shape are covered in our rental e-bike fleet guide. This is the pattern that most needs a disciplined station procurement process, because the station layout constrains where vehicles can be used at all.
Pilot to City-Wide Scale
Operators planning to scale use the pilot batch to measure decommission and theft rates, battery swap cadence and downtime per vehicle, and those figures then justify the scale order, the spares ratio and the field-operation training plan. Field-swap and depot processes are designed jointly before the larger order ships. The station layer is the part that must be re-specified at scale, because a pilot's ad-hoc charging arrangement is rarely the shape a city-wide network needs. Lease and staged-payment structures that spread a station build across budget years are covered in our fleet financing guide.
Certification and Site Compliance
Station hardware sits at the intersection of electrical safety and vehicle regulation, so it carries obligations the vehicles do not. Confirm the following before the order, not at installation:
- Vehicle-side certification. EN 17128 for personal light electric vehicles, UL 2272 for the electrical system, and UN 38.3 for the battery as shipped. Station hardware does not excuse these, it depends on them being present.
- Charger certification. Chargers on this platform cover 36V–84V output at 84–840W with universal AC 100–240V input and above 90% conversion efficiency, and the safety case is the charger's own certification rather than the vehicle's.
- Ingress protection. Outdoor station hardware needs a defined IP rating for the climate it is installed in. The vehicles on this platform carry an IP67 electronics seal, which is a different rating from the station enclosure and should never be assumed to transfer.
- Permit conditions. Cities mandate technical requirements per permit, and the station layout is frequently named in them. Read the permit before drawing the layout.
The Site Survey That Prevents the Cost Overrun
Do these five checks before the station order is placed. Each one has caused a re-quote on a real programme.
- Count available power, not positions. An existing supply may support the fleet but not the peak simultaneous load. Establish the kW ceiling first and design wave scheduling to fit inside it.
- Confirm who owns the electrical work. If the operator is a tenant, the site owner may control the supply. Establish permission and cost responsibility in writing before design.
- Map the vehicle-to-position ratio. A station network sized for peak occupancy wastes capital; one sized for average occupancy fails on peak days. Note which vehicles are permitted at which positions and by what interface.
- Decide the pack handling flow. If packs move between vehicle and cabinet, that path defines the labour cost and the security requirement. If they do not, the architecture is docks and the civil cost returns.
- Fix the spares ratio. Station hardware, chargers and packs all need spares, and the ratio follows from measured downtime in the pilot rather than from a supplier's default.
Spec a Station That Outlives the Vehicle Order
The station layer is the part of a programme that is hardest to change later and easiest to under-specify at the start. Choose the architecture from the deployment pattern, size it from real pack arithmetic, standardise the interface across the whole programme and confirm the electrical ceiling before drawing the layout. Get those four right and the station stops being the line item that ruins the model.

Where to Start
If the station architecture is still open, decide it from the deployment pattern first and let the electrical survey follow. If it is already fixed, the fastest saving is usually in wave scheduling, which shifts peak load without changing any hardware. Either way, fix the connector interface across the whole programme before the first order ships, because that is the one part of the station layer that is expensive to change later.
