The 80kW multi-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 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 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. Every cabinet is load tested before shipment and arrives with a wiring map covering contactors, fuses and surge arrestors for fast commissioning. Input power factor stays above 0.99 and the wide input window keeps operation stable on weak rural feeders and long industrial spurs. A single controller supervises rectification, isolation and metering, which keeps the power path short and trims conversion losses across the whole load range. 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 Continuous insulation monitoring isolates the outlet whenever leakage approaches the configured threshold, protecting technicians and vehicles alike. 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 125A current ceiling. Constant power operation holds the full 80kW from roughly 500V upward, so an 800V pack charges at rated rate instead of tapering early. Output spans 200V to 1000V DC, covering 400V and 800V vehicle architectures from compact city cars to heavy-duty tractors.

3. 20kW 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 20kW hot-swappable modules, so a failed unit is exchanged in minutes without isolating the whole cabinet. N plus one redundancy keeps rated 80kW available even while one module is pulled for service, which matters on revenue-critical corridors. Each module reports voltage, current, temperature and fan speed to the controller, which derates or isolates any unit drifting out of tolerance. Modules slide out from the front, so service engineers never need rear clearance in tight parking layouts or wall-adjacent installations. Compatible EV charging connectors are listed separately.

4. Dynamic Power Allocation Across Dual Outlets 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. Operators set allocation rules per site, per connector or per tariff window through the cloud portal, with no on-site reprogramming. Matrix switching allows any module to serve any gun, so one cabinet can run a single 125A session or two lower-current sessions. Priority rules can reserve one outlet for emergency fleets while the other follows a normal queue, all configured remotely. Site rules are tuned from the operator portal.

5. Outdoor IP55 Enclosure Built for Public Sites Ambient range runs from minus 30 to plus 55 degrees Celsius, with internal heaters protecting the 7-inch display in freezing conditions. 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. Surge protection, residual current detection and emergency stop are integrated, and the cabinet is engineered for a ten-year outdoor service life. Front and side service access is available, and the base frame accepts either anchor bolts or a concrete plinth. 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 Drivers authenticate by RFID card, mobile app, QR code or ISO 15118 plug and charge, with an optional POS terminal for bank card payment. Communication runs over OCPP 1.6J, so the station integrates with almost any back office without custom middleware. OCPP 1.6J 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. The controller exposes smart charging profiles, so a central system can cap site load during peak tariff periods. 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

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.

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 80kW 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 80kW 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 80kW, 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.
