OneCharge Exclusive Talk
How SMS Group Became a Fleet Charging Pioneer in Thailand
Our conversation with Khem Wanglee of SMS Group on building one of the first EV fleet charging operations in Thailand.
Real fleets, real backends
Already Running on OneCharge
From logistics to container shipping, these fleet operators already manage charging through OneCharge.
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.

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 example: Bangchak Lat Krabang
At the Bangchak Lat Krabang site, three 240kW DC chargers run on the same OneCharge backend as Laem Chabang. The site owner manages all three units from one dashboard, and any fleet company charging there gets its own member account with prepaid credit.
