The 180kW dual-gun modular AC-DC fast charger targets public parking hubs and retail destinations, where uptime and quick service access decide revenue. With CCS2 outlets, a 200V-1000V DC window and OCPP 1.6J 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. Efficiency peaks at 96 percent and stays above 94 percent from light load to full output, cutting energy cost for high-utilisation sites. A single controller supervises rectification, isolation and metering, which keeps the power path short and trims conversion losses across the whole load range. Busbar layout, magnetic components and cooling channels are shared across the 180kW family, which shortens lead times and simplifies spare part stocking. Bidirectional-ready bus design lets the same platform accept solar or battery energy storage input without a second conversion stage. Matching power modules are documented in the datasheet.

2. 200V-1000V Wide Voltage Output With Constant Power Output spans 200V to 1000V DC, covering 400V and 800V vehicle architectures from compact city cars to heavy-duty tractors. Precision metering at the outlet delivers Class B accuracy, so billed energy matches what the vehicle actually receives. Voltage and current limits are negotiated over the control pilot, then confirmed by the battery management system before the DC contactors close. Wide range voltage tracking keeps efficiency above 95 percent even when a deeply depleted pack pulls close to the 250A current ceiling. Constant power operation holds the full 180kW from roughly 500V upward, so an 800V pack charges at rated rate instead of tapering early.

3. 30kW Hot-Swap Power Modules and N+1 Redundancy Replacement modules ship pre-calibrated, and the controller recognises a new unit automatically once it is fully seated. Power is delivered by 30kW hot-swappable modules, so a failed unit is exchanged in minutes without isolating the whole cabinet. Module-level diagnostics flag degrading fans and capacitors long before they cause a stoppage, enabling condition-based maintenance. Modules slide out from the front, so service engineers never need rear clearance in tight parking layouts or wall-adjacent installations. Speed-controlled fans and intelligent airflow keep acoustic noise near 65 dB, which suits residential, hospital and retail locations. A shared DC bus lets any module feed any outlet, removing the fixed pairing that limits conventional charging piles. Compatible EV charging connectors are listed separately.

4. Dynamic Power Allocation Across Dual Outlets Because capacity follows demand, the DC fast charging station avoids the idle-outlet penalty that drags down utilisation on paired connectors. When a second connector activates, the controller splits output according to state of charge rather than a fixed schedule. Dynamic power allocation distributes available capacity across outlets in real time, letting a single vehicle draw the full 180kW. Priority rules can reserve one outlet for emergency fleets while the other follows a normal queue, all configured remotely. Scheduling profiles prioritise buses in the morning and light vehicles in the evening without manual intervention. Session logs record delivered energy per outlet, which simplifies billing, reconciliation and fleet cost allocation. Site rules are tuned from the operator portal.

5. Outdoor IP55 Enclosure Built for Public Sites A powder-coated steel body with anti-corrosion treatment suits coastal, industrial and roadside installations. Each unit is ingress tested at the factory and ships with CE documentation covering insulation and earth continuity checks. Cable management hooks keep CCS2 leads off the ground, extending connector life in busy public car parks. Surge protection, residual current detection and emergency stop are integrated, and the cabinet is engineered for a ten-year outdoor service life. The enclosure is rated IP55, with filtered intake louvres and a sealed electronics compartment that shrugs off rain, dust and washdown. Optional heating, ventilation and lighting kits extend operation to cold storage yards and dusty mining roads. Installation drawings cover plinth and cable routing.

6. Smart Payment, OCPP Management and Energy Integration Multi-language interface, configurable tariff screens and branded start pages help operators monetise the charging session itself. Drivers authenticate by RFID card, mobile app, QR code or ISO 15118 plug and charge, with an optional POS terminal for bank card payment. OCPP 1.6J adds certificate handling and stronger message security for public networks that must satisfy national roaming rules. Remote diagnostics, firmware updates and tariff changes are pushed over the air, cutting truck rolls for routine maintenance. Communication runs over OCPP 1.6J, so the station integrates with almost any back office without custom middleware. Local storage keeps sessions running if connectivity drops, then synchronises records once the link returns. 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 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.

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 180kW unit support?

The charger delivers 200V to 1000V DC at up to 250A, so it serves 400V passenger cars and 800V heavy vehicles from the same outlet. Constant power holds 180kW 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 180kW, 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.
