The 210kW dual-gun modular AC-DC fast charger targets highway service corridors, 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 Power conversion is separated from control logic, so firmware updates and diagnostics never interrupt an active charging session. Galvanic isolation between grid and vehicle protects both sides during fault events and meets the insulation requirements behind CE and IEC 61851 compliance. An active front end feeds isolated DC/DC stages inside each cabinet, so grid harmonics stay low while output voltage follows whatever the battery management system requests. 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 A 1000V ceiling future-proofs the investment, because the same DC fast charging station serves today’s 400V fleets and tomorrow’s 800V platforms. Voltage and current limits are negotiated over the control pilot, then confirmed by the battery management system before the DC contactors close. Cable assemblies rated 250A to 400A are matched to each outlet, and CCS2 leads are available in lengths from 4 to 8 metres. Precision metering at the outlet delivers Class B accuracy, so billed energy matches what the vehicle actually receives. Constant power operation holds the full 210kW 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 Thermal design holds junction temperatures stable at 50 degrees ambient, so the DC fast charger sustains rated output in hot climates. Modules slide out from the front, so service engineers never need rear clearance in tight parking layouts or wall-adjacent installations. N plus one redundancy keeps rated 210kW available even while one module is pulled for service, which matters on revenue-critical corridors. A shared DC bus lets any module feed any outlet, removing the fixed pairing that limits conventional charging piles. Module-level diagnostics flag degrading fans and capacitors long before they cause a stoppage, enabling condition-based maintenance. Compatible EV charging connectors are listed separately.

4. Dynamic Power Allocation Across Dual Outlets Load balancing also watches site demand, trimming total draw when the transformer or building load approaches its limit. Priority rules can reserve one outlet for emergency fleets while the other follows a normal queue, all configured remotely. Dynamic power allocation distributes available capacity across outlets in real time, letting a single vehicle draw the full 210kW. Because capacity follows demand, the DC fast charging station avoids the idle-outlet penalty that drags down utilisation on paired connectors. 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 Surge protection, residual current detection and emergency stop are integrated, and the cabinet is engineered for a ten-year outdoor service life. Ambient range runs from minus 30 to plus 55 degrees Celsius, with internal heaters protecting the 7-inch display in freezing conditions. A powder-coated steel body with anti-corrosion treatment suits coastal, industrial and roadside installations. The enclosure is rated IP55, with filtered intake louvres and a sealed electronics compartment that shrugs off rain, dust and washdown. The bonded anti-glare touchscreen stays readable in direct sunlight and remains responsive through gloved operation. Cable management hooks keep CCS2 leads off the ground, extending connector life in busy public car parks. Installation drawings cover plinth and cable routing.

6. Smart Payment, OCPP Management and Energy Integration An open API and Modbus TCP option let the DC fast charger link with solar, storage and building management systems. 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. Multi-language interface, configurable tariff screens and branded start pages help operators monetise the charging session itself. OCPP 1.6J adds certificate handling and stronger message security for public networks that must satisfy national roaming rules. Communication runs over OCPP 1.6J, 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

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.
