The 90kW 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 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 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. 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 90kW family, which shortens lead times and simplifies spare part stocking. Galvanic isolation between grid and vehicle protects both sides during fault events and meets the insulation requirements behind CE and IEC 61851 compliance. 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 Voltage and current limits are negotiated over the control pilot, then confirmed by the battery management system before the DC contactors close. Continuous insulation monitoring isolates the outlet whenever leakage approaches the configured threshold, protecting technicians and vehicles alike. A 1000V ceiling future-proofs the investment, because the same DC fast charging station serves today’s 400V fleets and tomorrow’s 800V platforms. 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 90kW from roughly 500V upward, so an 800V pack charges at rated rate instead of tapering early.

3. 20kW Hot-Swap Power Modules and N+1 Redundancy Speed-controlled fans and intelligent airflow keep acoustic noise near 65 dB, which suits residential, hospital and retail locations. 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 90kW 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. 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 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. Dynamic power allocation distributes available capacity across outlets in real time, letting a single vehicle draw the full 90kW. 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. 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 Front and side service access is available, and the base frame accepts either anchor bolts or a concrete plinth. Surge protection, residual current detection and emergency stop are integrated, and the cabinet is engineered for a ten-year outdoor service life. Cable management hooks keep CCS2 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. Ambient range runs from minus 30 to plus 55 degrees Celsius, with internal heaters protecting the 7-inch display in freezing conditions. Installation drawings cover plinth and cable routing.

6. Smart Payment, OCPP Management and Energy Integration Communication runs over OCPP 1.6J, so the station integrates with almost any back office without custom middleware. 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. An open API and Modbus TCP option let the DC fast charger link with solar, storage and building management systems. 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 90kW 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 90kW 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 90kW, 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.
