Laos Parking-Lot DC Fast Charging Case Study

Nancome one-stop delivery: 160 kW GB/T + CCS2 floor-standing chargers

Laos is in the early stage of EV adoption, with growth led by urban taxis and ride-hailing; public DC fast-charging corridors are emerging but must cope with mixed GB/T and CCS2 standards from imported vehicles. Government and utilities back cleaner transport and are testing tariffs and incentives, while operators prioritize rain-proof canopies, reliable QR/RFID payments and responsive O&M. A 160 kW floor-standing GB/T + CCS2 charger with an OCPP backend therefore offers a future-proof, audit-ready solution for the site.

1) Project Overview

· Location: Urban parking lot, Laos (on-site photos available).
· Objective: Fast top-ups for taxis, ride-hailing fleets, and public users; increase bay turnover and monetize dwell time.
· Configuration: Nancome charger station EV floor-standing units rated at 160 kW DC with GB/T + CCS2 dual standards, dual-gun power sharing; spare conduits reserved for additional bays and future scaling.
· Delivery Model: Nancome solutions + service + one-stop + customization + backend support—from load study and civil works to commissioning and O&M.

2) Site Context & Challenges

· Fluctuating traffic: Daytime short stays versus evening long parking.
· Grid headroom: Downtown feeder required staged capacity and peak-capping.
· Outdoor environment: Heat and rain—canopy, IP-rated enclosures, and managed cable reach were required.

3) Solution Design

Power Layout
· Deployed a lane of ev dc fast charging station for parking lot with clear ground markings and bollards.
· 160 kW GB/T + CCS2 cabinets positioned for forward-in, straight-out flow; maintenance aisle behind units.
· Lighting + drainage canopy improves visibility and night operations.

User Experience
· Dual-gun power sharing optimizes concurrency (e.g., 160 kW single car or dynamic split for two cars).
· Tap-and-go/QR/RFID; Plug-and-Charge can be enabled where supported.
· Large screens on the floor-standing units display pricing, status, and prompts.

Backend Operations
· OCPP EV charger backend with dynamic tariffs, kWh/min/session billing, memberships/coupons, and peak capping.
· Remote diagnostics, OTA updates, alarms, and auto reports guide pricing and staffing.

4) Implementation Highlights

· Curbside bays with canopy: safe approach and protected cable paths.
· Fleet use case: 20–35-minute top-ups at 160 kW get taxis back in service quickly.
· Multi-bay array: clear wayfinding and turning radii; maintenance aisle for rapid service.

5) Outcomes & ROI Snapshot*

Ranges from comparable Nancome deployments; actuals depend on local tariffs, traffic, and vehicle mix.
· Utilization ramp: ~10–15% in month 1, trending to 22–35% in 3–6 months as apps/POI listings grow.
· Driver experience: Peak-hour wait down ~30–45%; predictable fast sessions with 160 kW power.
· Monetization: Charging fees + parking/service fees + nearby retail uplift → clear path to commercial EV charging station profit.
· Payback window: With 160 kW anchors (plus a few 60/120 kW satellite bays), positive cash flow commonly within 18–30 months.

6) Scalable Roadmap

· Anchor power: Keep 160 kW GB/T + CCS2 as primary fast-turn bays.
· Coverage growth: Add cost-efficient dc fast charging station 60kW in long-stay rows to 'fill valleys'.
· Throughput upgrade: Convert hot spots to dc fast charging station 120kW or additional 160 kW as peaks emerge.
· Energy optimization (optional): PV canopies + storage for peak shaving and further OPEX control.

7) Why Nancome

· Solution-first: We deliver a complete charging business, not just hardware.
· One-stop delivery: Grid application, civil works, cabinets, software, and maintenance under one partner.
· Customization backend: OCPP integrations, tariff logic, marketing tools, and reporting aligned to P&L.
· Proven ROI: Modular design, dual-gun sharing, and data-driven operations shorten the road to profitability.

Result: The Laos project shows how a staged, floor-standing 160 kW GB/T + CCS2 deployment with an OCPP backend can transform a city parking lot into reliable infrastructure and recurring revenue—backed by Nancome’s solution, service, and long-term support.
