The 210kW dual-gun modular AC-DC fast charger targets public parking hubs and retail destinations, where uptime and quick service access decide revenue. With CCS1 and GBT 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 Every cabinet is load tested before shipment and arrives with a wiring map covering contactors, fuses and surge arrestors for fast commissioning. 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. Input power factor stays above 0.99 and the wide input window keeps operation stable on weak rural feeders and long industrial spurs. 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 Wide range voltage tracking keeps efficiency above 95 percent even when a deeply depleted pack pulls close to the 250A current ceiling. Continuous insulation monitoring isolates the outlet whenever leakage approaches the configured threshold, protecting technicians and vehicles alike. Constant power operation holds the full 210kW from roughly 500V upward, so an 800V pack charges at rated rate instead of tapering early. Precision metering at the outlet delivers Class B accuracy, so billed energy matches what the vehicle actually receives. Output spans 200V to 1000V DC, covering 400V and 800V vehicle architectures from compact city cars to heavy-duty tractors.

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. Module-level diagnostics flag degrading fans and capacitors long before they cause a stoppage, enabling condition-based maintenance. Each module reports voltage, current, temperature and fan speed to the controller, which derates or isolates any unit drifting out of tolerance. Power is delivered by 30kW hot-swappable modules, so a failed unit is exchanged in minutes without isolating the whole cabinet. A shared DC bus lets any module feed any outlet, removing the fixed pairing that limits conventional charging piles. Commissioning takes under an hour with the guided setup wizard. Compatible EV charging connectors are listed separately.

4. Dynamic Power Allocation Across Dual Outlets Priority rules can reserve one outlet for emergency fleets while the other follows a normal queue, all configured remotely. Operators set allocation rules per site, per connector or per tariff window through the cloud portal, with no on-site reprogramming. Because capacity follows demand, the DC fast charging station avoids the idle-outlet penalty that drags down utilisation on paired connectors. 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. Load balancing also watches site demand, trimming total draw when the transformer or building load approaches its limit. Site rules are tuned from the operator portal.

5. Outdoor IP55 Enclosure Built for Public Sites The enclosure is rated IP55, with filtered intake louvres and a sealed electronics compartment that shrugs off rain, dust and washdown. A powder-coated steel body with anti-corrosion treatment suits coastal, industrial and roadside installations. Cable management hooks keep CCS1 and GBT leads off the ground, extending connector life in busy public car parks. Each unit is ingress tested at the factory and ships with CE documentation covering insulation and earth continuity checks. Front and side service access is available, and the base frame accepts either anchor bolts or a concrete plinth. 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 Every session produces a metered record covering start, stop and energy delivered, mapping directly to the operator’s billing engine. Multi-language interface, configurable tariff screens and branded start pages help operators monetise the charging session itself. The controller exposes smart charging profiles, so a central system can cap site load during peak tariff periods. Drivers authenticate by RFID card, mobile app, QR code or ISO 15118 plug and charge, with an optional POS terminal for bank card payment. Local storage keeps sessions running if connectivity drops, then synchronises records once the link returns. Remote diagnostics, firmware updates and tariff changes are pushed over the air, cutting truck rolls for routine maintenance. 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 210kW 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 210kW 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 210kW, 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 1.6J 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.
