The 150kW 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 Power conversion is separated from control logic, so firmware updates and diagnostics never interrupt an active charging session. The 150kW dual-gun unit is built around a modular AC-DC topology that rectifies three-phase AC input onto a regulated DC bus before power reaches the vehicle inlet. Busbar layout, magnetic components and cooling channels are shared across the 150kW family, which shortens lead times and simplifies spare part stocking. 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. A 1000V ceiling future-proofs the investment, because the same DC fast charging station serves today’s 400V fleets and tomorrow’s 800V platforms. Cable assemblies rated 250A to 400A are matched to each outlet, and CCS2 leads are available in lengths from 4 to 8 metres. Constant power operation holds the full 150kW from roughly 500V upward, so an 800V pack charges at rated rate instead of tapering early. Pre-charge sequencing limits inrush current, shielding vehicle contactors and DC link capacitors from stress during every plug-in.

3. 30kW 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. Thermal design holds junction temperatures stable at 50 degrees ambient, so the DC fast charger sustains rated output in hot climates. 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. 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 Because capacity follows demand, the DC fast charging station avoids the idle-outlet penalty that drags down utilisation on paired connectors. 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 250A session or two lower-current sessions. When a second connector activates, the controller splits output according to state of charge rather than a fixed schedule. 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. Ambient range runs from minus 30 to plus 55 degrees Celsius, with internal heaters protecting the 7-inch display in freezing conditions. Optional heating, ventilation and lighting kits extend operation to cold storage yards and dusty mining roads. The enclosure is rated IP55, with filtered intake louvres and a sealed electronics compartment that shrugs off rain, dust and washdown. Surge protection, residual current detection and emergency stop are integrated, and the cabinet is engineered for a ten-year outdoor service life. 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. OCPP 1.6J adds certificate handling and stronger message security for public networks that must satisfy national roaming rules. The controller exposes smart charging profiles, so a central system can cap site load during peak tariff periods. 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. 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 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 150kW 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 150kW 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 150kW, 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.

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.
