High-Capacity DC Fast Charging Hardware for Sri Lanka
Standardized OEM modules pre-calibrated to IEC and CE compliance, built to support long charging cycles under continuous operations.
Sri Lanka EV Transition: Overcoming Energy Realities
Decarbonizing logistics, passenger transport, and commercial fleets along the Colombo-Katunayake expressway and port economic corridors.
Mitigating Peak Fuel Volatility
Sri Lanka’s macroeconomic reliance on imported fossil fuels has triggered urgent governmental policy shifts targeting 100% electrified public transport and commercial fleets by 2040. Adopting large-scale split-type charging topologies enables private CPOs and government transport boards (SLTB) to scale megawatt charging while retaining strict operational efficiency.
Ceylon Electricity Board (CEB) Grid Adaptation
The island's medium-voltage distribution network often faces voltage fluctuations and regional load bottlenecks. Traditional integrated dual-gun DC chargers draw sudden high-peak kVA loads, tripping local substations. A split-type system distributes power dynamically, managing surge ramps and protecting regional substation assets.
Equatorial Maritime Durability
With humidity reaching 90% and intense airborne salt spray along maritime zones like Galle, Hambantota, and Colombo Port City, standard charging piles suffer PCB corrosion within 18 months. Our OEM split-type designs isolate the power electronics inside an IP55-rated, heat-exchanger-cooled central cabinet, leaving compact IP54 dispensers outdoors.
Distributed Split Matrix Architecture vs. Integrated DC Charging
Understanding why utility-scale charging sites in South Asia migrate from monobloc chargers to dynamic power pooling power cabinets.
The Dynamic Matrix Power Stacking Topology
In standard monolithic DC chargers, power modules are locked directly behind two dispensers. If an electric vehicle requires only 60kW at a 180kW station, the remaining 120kW is held hostage. Split-type configurations aggregate 20kW or 30kW high-efficiency AC/DC rectifiers into a single central control core (e.g., 360kW up to 720kW).
Using high-speed programmable logic controllers (PLCs) and a contactor matrix, the cabinet shifts discrete 20kW/30kW blocks on-demand to individual satellite terminals. A logistics van drawing 60kW, an intercity bus requesting 240kW, and a passenger vehicle taking 90kW are all served simultaneously without wasting energy capacity.
Minimized Footprint in Congested Prime Zones
Colombo commercial centers, expressway rest hubs, and bus terminals often lack the physical clearance for bulky individual all-in-one charging cabinets at each bay. The split-type layout shifts the heavy, noisy power generation core up to 100 meters away into a secure utility room or peripheral substation perimeter.
At the parking bay, only ultra-compact, user-friendly dispenser terminals are installed. These terminals contain no heavy magnetic parts, operate silently, provide liquid-cooled or air-cooled CCS2 charging cables, and deliver an elevated user experience via integrated touchscreens and POS integration.
Targeted Deployment Scenarios Across Sri Lanka
Tailored high-power EVSE implementations designed to fit specific geographic, commercial, and operational constraints.
E01 / E02 Expressway Corridors
The Southern Expressway connects Colombo to Matara and Hambantota, representing Sri Lanka’s most critical commercial transit artery. Deploying 480kW split systems at rest plazas allows fast top-ups for cross-island travelers. 8 bays can be powered concurrently, keeping turnaround under 20 minutes.
Port City & Logistics Hubs
The Port of Colombo and industrial export zones in Katunayake and Biyagama utilize light commercial trucks and inland drayage vans. Split charging units provide overnight and turnaround depot charging, matching current requirements without over-stressing transformer infrastructure.
Luxury Tourism & Hotel Chains
High-end eco-resorts in Kandy, Bentota, and Galle require discreet, noiseless EV charging systems. The central power core sits hundreds of meters away, allowing hotel guests to charge without humming noise while the hotel gains high-end brand equity.
Stringent International Standards with Localized Protection
Built under strict ISO 9001 quality management, fully compatible with Sri Lankan CEB/LECO utility interconnection regulations.
Certified Electrical Isolation & Safety Stack
Our split-type chargers feature Class B surge protection (SPD), residual direct-current detecting devices (RDC-DD), insulation resistance monitoring (≥500V DC / ≥1000V DC), over-temperature monitoring at terminal connector contact pins, and automated phase imbalance mitigation. Systems maintain strict compliance with IEC 61851-1, IEC 61851-23, and IEC 62196-3 standards.
Open Charge Point Protocol (OCPP) 1.6J & 2.0.1
Seamless backend integration with existing CPO platforms in South Asia. Stations include 4G LTE modems with dual-SIM auto-failover, ethernet interfaces, and complete compatibility with regional payment systems, RFID reader validation, dynamic pricing APIs, and remote telemetry fault isolation.

The Future: Solar-Storage-Charging Microgrids
How Sri Lankan commercial hubs can leverage renewable resources to bypass distribution transformer limits.
Direct DC Microgrid Coupling
Sri Lanka receives abundant year-round solar irradiance (5.5–6.0 kWh/m²/day). Our forward-looking split matrices incorporate direct DC bus integration ports. Instead of converting PV energy DC to AC and back to DC inside the vehicle, power flows directly from rooftop solar arrays to the charging battery via DC-DC converters, eliminating multi-stage conversion losses.
LFP Energy Storage Integration
To eliminate demand-charge penalties from local distribution utilities, our central power cabinets integrate seamlessly with 100kWh–500kWh stationary lithium iron phosphate (LiFePO4) storage units. The batteries recharge during low-cost overnight periods and discharge into high-demand fleets during afternoon peak tariff windows.
Megawatt Charging System (MCS) Ready
Heavy commercial logistics, shipping container terminal movers, and port tractors will require high-speed megawatt charging interfaces. The modular architecture of our 720kW split cabinet allows parallel interconnectivity, enabling future upgrades to deliver >1000A charging sessions without tearing out installed power delivery conduits.
