The 100kW dual-gun modular AC-DC fast charger targets public parking hubs and retail destinations, where uptime and quick service access decide revenue. With CCS2 and CCS1 outlets, a 200V-1000V DC window and OCPP 2.0.1 connectivity, it delivers predictable high-power charging while keeping installation and commissioning simple. This DC fast charging station pairs high utilisation with low maintenance overhead.

1. Modular AC-DC Power Topology and Conversion Chain Galvanic isolation between grid and vehicle protects both sides during fault events and meets the insulation requirements behind CE and IEC 61851 compliance. Busbar layout, magnetic components and cooling channels are shared across the 100kW family, which shortens lead times and simplifies spare part stocking. Efficiency peaks at 96 percent and stays above 94 percent from light load to full output, cutting energy cost for high-utilisation sites. The 100kW dual-gun unit is built around a modular AC-DC topology that rectifies three-phase AC input onto a regulated DC bus before power reaches the vehicle inlet. Commissioning takes under an hour with the guided setup wizard. Matching power modules are documented in the datasheet.

2. 200V-1000V Wide Voltage Output With Constant Power A 1000V ceiling future-proofs the investment, because the same DC fast charging station serves today’s 400V fleets and tomorrow’s 800V platforms. Cable assemblies rated 250A to 400A are matched to each outlet, and CCS2 and CCS1 leads are available in lengths from 4 to 8 metres. Wide range voltage tracking keeps efficiency above 95 percent even when a deeply depleted pack pulls close to the 125A current ceiling. Pre-charge sequencing limits inrush current, shielding vehicle contactors and DC link capacitors from stress during every plug-in. Continuous insulation monitoring isolates the outlet whenever leakage approaches the configured threshold, protecting technicians and vehicles alike.

3. 20kW Hot-Swap Power Modules and N+1 Redundancy Module-level diagnostics flag degrading fans and capacitors long before they cause a stoppage, enabling condition-based maintenance. Power is delivered by 20kW hot-swappable modules, so a failed unit is exchanged in minutes without isolating the whole cabinet. Thermal design holds junction temperatures stable at 50 degrees ambient, so the DC fast charger sustains rated output in hot climates. N plus one redundancy keeps rated 100kW available even while one module is pulled for service, which matters on revenue-critical corridors. Speed-controlled fans and intelligent airflow keep acoustic noise near 65 dB, which suits residential, hospital and retail locations. Compatible EV charging connectors are listed separately.

4. Dynamic Power Allocation Across Dual Outlets When a second connector activates, the controller splits output according to state of charge rather than a fixed schedule. Matrix switching allows any module to serve any gun, so one cabinet can run a single 125A session or two lower-current sessions. Dynamic power allocation distributes available capacity across outlets in real time, letting a single vehicle draw the full 100kW. Session logs record delivered energy per outlet, which simplifies billing, reconciliation and fleet cost allocation. Operators set allocation rules per site, per connector or per tariff window through the cloud portal, with no on-site reprogramming. Site rules are tuned from the operator portal.

5. Outdoor IP55 Enclosure Built for Public Sites Optional heating, ventilation and lighting kits extend operation to cold storage yards and dusty mining roads. Front and side service access is available, and the base frame accepts either anchor bolts or a concrete plinth. A powder-coated steel body with anti-corrosion treatment suits coastal, industrial and roadside installations. Ambient range runs from minus 30 to plus 55 degrees Celsius, with internal heaters protecting the 7-inch display in freezing conditions. Cable management hooks keep CCS2 and CCS1 leads off the ground, extending connector life in busy public car parks. The bonded anti-glare touchscreen stays readable in direct sunlight and remains responsive through gloved operation. Installation drawings cover plinth and cable routing.

6. Smart Payment, OCPP Management and Energy Integration OCPP 2.0.1 adds certificate handling and stronger message security for public networks that must satisfy national roaming rules. Multi-language interface, configurable tariff screens and branded start pages help operators monetise the charging session itself. Remote diagnostics, firmware updates and tariff changes are pushed over the air, cutting truck rolls for routine maintenance. Every session produces a metered record covering start, stop and energy delivered, mapping directly to the operator’s billing engine. An open API and Modbus TCP option let the DC fast charger link with solar, storage and building management systems. Communication runs over OCPP 2.0.1, so the station integrates with almost any back office without custom middleware. Backend integration follows the OCPP specification.

Deployment Support and Accessories

Projects usually pair the cabinet with Type 2 to Type 2 cables and a OCPP protocol controllers, all supplied from one factory. Engineering teams can review the company profile before order, while commercial questions go through the contact our team page. Standard builds ship in four to six weeks, and documentation covers wiring, grounding and network setup.

Frequently Asked Questions

What payment options are available for public drivers?

RFID card, mobile app, QR code, ISO 15118 plug and charge and an optional POS terminal for contactless bank cards. All methods write to the same metered session record, so reconciliation stays simple. Connector options are listed on our EV charging connector page.

What output voltage range does the 100kW unit support?

The charger delivers 200V to 1000V DC at up to 125A, so it serves 400V passenger cars and 800V heavy vehicles from the same outlet. Constant power holds 100kW from about 500V upward, which shortens charging time on modern high-voltage packs.

How does DCDC architecture differ from a conventional AC-DC charger?

A DCDC stage accepts a DC bus from solar or battery storage and converts it directly, skipping one rectification step. That raises round-trip efficiency and lets the modular AC-DC platform operate during grid outages when paired with a BESS cabinet.

Can the two guns charge at the same time at full power?

Yes, with dynamic allocation. Total capacity is shared, so one vehicle can take the full 100kW, or two vehicles can split it according to state of charge. Matrix switching means any module can serve either outlet, and rules are configured remotely.

Which OCPP version should an operator choose?

OCPP 1.6J covers the widest installed base of back offices today. OCPP 2.0.1 is specified here for certificate handling, plug and charge support and stronger message security. Both profiles work with standard roaming hubs, and the protocol controller datasheet explains the mapping.

What protection level is needed for roadside installation?

IP55 is the baseline for outdoor public sites, combined with surge arrestors, residual current detection and an emergency stop. Coastal or dusty locations should add the anti-corrosion coating and filter service kit.

How is maintenance handled when a power module fails?

Modules are hot-swappable from the front. A technician isolates the affected unit, slides it out and seats a pre-calibrated replacement while the second outlet keeps serving traffic. N plus one redundancy keeps rated output available throughout.

Does the station support solar and battery storage integration?

The DC bus is storage-ready. Solar MPPT or a BESS cabinet can feed the link directly, and the controller can cap grid import during peak tariffs. This suits microgrid and carport projects where demand charges dominate operating cost.
