Before / after
Where fleet charging breaks down — and how OneCharge fixes it
The same friction shows up in every growing fleet. Here’s what changes once it runs on OneCharge.
Without a dedicated fleet platform
- Need to charge many vehicles at once in a limited window.
- Need tight control over electricity costs.
- Drivers wait to get reimbursed after every charging stop instead of just driving on.
- No single view of which vehicle charged where, when, and how much it cost.
With OneCharge
- Automated charge scheduling — Queue vehicles by priority automatically.
- Export energy usage data — Calculate cost per vehicle downstream.
- Centralized team wallet — Top up once and let the whole fleet charge across the network — no per-vehicle reimbursement chasing.
- Safer AutoCharge via MAC address — Pair each vehicle to its own MAC address, so a driver can't accidentally charge on the wrong vehicle's RFID.
Built for how fleets actually run
The Same Platform, Built for Scale
Fleet operators run on the same core platform every OneCharge site uses.
Any charger, any brand
OCPP-native and hardware-agnostic, so a mixed fleet of charger brands is never a problem.
RFID & AutoCharge
Drivers tap a card or just plug in and go — no app required at the charger itself.
Load-balanced by design
Charging many vehicles overnight without tripping the depot’s power limit — see the Fleet depot solution for how it works.
See Fleet depot →Two ways to authenticate
RFID Card or AutoCharge — Your Fleet's Choice
Every OneCharge charger supports both, so you can mix and match by vehicle or by driver.
Tap the card to see the back
RFID Charge Card
Drivers tap a physical card at the charger to start a session — no phone, no app.
Best for
- Shared vehicles with rotating drivers
- Drivers without a smartphone or data plan
- Reassigning access between vehicles instantly
Keep in mind
- Cards can be lost or forgotten
- Needs a process for issuing and revoking lost cards
- Watch for drivers using the card on a personal vehicle or lending it to someone else
AutoCharge (MAC Address)
The vehicle is recognized the moment it's plugged in — charging starts with no card or tap.
Best for
- Unattended overnight depot charging
- Fixed vehicle-to-driver assignments
- Nothing for drivers to carry or lose
Keep in mind
- Registered to OneCharge's backend, not paired to a specific charger
- If the vehicle is sold or swapped out, remove it from the system — otherwise its access stays active

How it works
One platform, two backends
A site owner and the fleet companies that charge there don't have to share one login. OneCharge gives each side its own view — and its own billing.
Real example: Laem Chabang
At Laem Chabang, ProCharge owns and operates the station on OneCharge. Fleet companies like FLS Transport and SCG JWD use OneCharge as their own backend to add their trucks, and get member pricing with prepaid credit — so drivers charge without stopping to pay, and the fleet gets one consolidated invoice instead of per-driver receipts.
Real stations, running today
Fleet charging, on the ground
A look at real OneCharge sites already serving fleets across Thailand.
Bangchak KMITL Lat Krabang
240kW × 4 chargers · 8 connectors · trucks, large vehicles, and passenger cars
A public station inside a Bangchak forecourt, sized for logistics traffic — four 240kW DC chargers with eight connectors serve everything from container trucks to daily passenger EVs, all running through OneCharge's Fleet system, which splits Public and Member pricing automatically.

Huawei 720kW · 8 connectors · electric trucks and regular cars
A high-power public site built around Huawei's 720kW platform — eight connectors mean multiple trucks and passenger cars can charge at the same time instead of queuing for a single bay.

Bangchak Laem Chabang (Super K Power)
360kW × 4 chargers · 8 connectors · 500A liquid-cooled cables
Run by site partner Super K Power, this station pairs 360kW chargers with liquid-cooled 500A cables — built for the heavy, repeat charging that traffic in and out of the container yard needs.
