480kW 360kW Dual Gun DC EV Charger CCS1 CCS2 CHAdeMO GB/T Highway Service Area Fast Charging Station

One cabinet platform covers eight power steps, so a network can start with a single 120kW bay and grow to a 480kW corridor site using the same operating interface, the same spare parts and the same driver experience.

Because the output voltage window reaches DC1000V, the same station serves 400V architecture cars and 800V architecture vehicles without a hardware change.

A dual gun cabinet is a power allocation decision as much as a hardware decision. When one vehicle is connected, the full module capacity is available to that gun, up to the 250A per gun limit. When two vehicles are connected, the cabinet splits the available power between the two sessions so both drivers leave with a usable charge instead of one bay waiting idle.

Queue management. On a busy corridor the constraint is usually bay turnover, not peak power. Two guns on one cabinet double the number of vehicles served per square metre of site, which matters where the lease area or the grid connection is fixed.

Connector flexibility. The two guns can carry different connector standards, for example CCS2 on one side and CHAdeMO or GB/T on the other, so a site does not turn away a vehicle because the wrong nozzle is fitted. Each gun is rated for 250A and the DC200V-1000V window.

Site design. Pull through bays suit vehicles with trailers and light commercial vans, while nose in bays save space in parking structures. Cable reach is 5m as standard, which covers most bay layouts when the cabinet is mounted between the two parking positions.

The cabinet is rated IP55 and runs from -40°C to +60°C with air cooling. On a corridor site the enclosure faces sun, rain, road salt and dust in the same week, so sealing and thermal design are specified as one system rather than as separate parts.

Cold start is handled by the sealed cabinet limiting frost and condensation on control boards and terminals, while continuous internal air circulation keeps the power module stack above the condensation threshold during long sub-zero idle periods. At the hot end, temperature controlled air cooling manages module heat so output is held inside the specified window instead of being throttled at the hottest part of the day.

Six independent protection functions run continuously during a charging session. Each one trips locally, so a fault is contained at the station instead of propagating to the vehicle or to the upstream distribution board.

Short circuit. Output is cut immediately when a fault current path is detected. Over temperature. Power is reduced or stopped before module and connector temperatures reach a damaging level. Over current. Output current is capped so cable, connector and vehicle inlet stay inside their rating.

Leakage. Residual current is monitored and the session is interrupted on detection. Over voltage. Output is limited when the requested voltage or grid side voltage exceeds the safe range. Under voltage. The session is held or stopped when supply voltage drops below the operating threshold.

All protection events are reported over OCPP 1.6J, so the operator sees the fault code in the CMS rather than learning about it from the driver.

Five start modes are supported on the same unit, and the operator can enable or disable each one from the backend. That matters on a corridor site where visiting drivers come from different networks and different countries.

RF card. Subscription fleets and closed depots: the driver taps the card on the reader, connects the gun and the session starts. Mobile APP. Public networks with account based billing: the driver selects the station in the APP, confirms and connects the gun.

CMS. Remote assistance: the operator starts the session from the backend console when a driver calls in. QR code. Walk up charging without a card: the driver scans the on-screen code, pays in the web page and connects the gun. VIN code. Plug and charge style fleet operation: the vehicle identity is read and authorization is automatic.

The station speaks OCPP 1.6J and offers 4G, Ethernet and WiFi, so integration does not depend on one carrier or one site layout. OCPP 1.6J provides the CMS connection path for roaming, remote start and stop, tariff profiles and firmware upgrade. Cellular covers corridor sites without fixed line access, Ethernet suits depots and logistics yards with existing cabling, and WiFi covers indoor parking and temporary installations.

Because both guns report through the same controller, the operator sees per gun status, session energy and fault codes in one place, and a firmware update applies to both sides of the cabinet at once.

• 60kW / 120kW / 160kW / 240kW single or dual gun configuration
• 180kW / 320kW / 360kW / 480kW high power configuration
• CCS1 + CCS2 / CCS1 + CHAdeMO / GB/T + CCS2 connector combinations
• 4G, Ethernet or WiFi communication module
• OEM enclosure color, logo and cabinet height

• Highway service areas and expressway corridors
• Public parking lots and charging hubs
• Commercial plazas and retail sites
• Fleet depots and logistics yards

Most installation delays come from site preparation rather than from the charger. Confirming six items before the cabinet ships keeps the commissioning schedule predictable: a three-phase 5-wire AC380V supply with capacity margin for the selected power rating; a level concrete base or plinth sized for the dual gun cabinet footprint and cable entry position; the cable distance from the distribution board together with the trench or tray path; an earthing arrangement that satisfies the local electrical code; surge protection coordinated with the building or yard system; and either usable 4G signal at the bays, an Ethernet drop, or WiFi coverage from the site access point.

Every unit is tested before shipment and covered by TUV, CE and FCC certification. OEM and ODM programs are available: enclosure branding, connector configuration, power module rating, language packs and CMS/OCPP integration can all be tailored to your project specification.

TUV provides independent safety and performance verification accepted by European project owners, CE is the conformity marking required for placement on the EU market, and FCC covers electromagnetic compliance for the North American market. For private label programs, branding, connector mix, power rating and language package are defined at order stage, while the electrical architecture and protection set stay fixed because they carry the certification.

How does the cabinet share power between two guns?

With one vehicle connected the full module capacity is available to that gun up to 250A. With two connected, the available power is split between the sessions so both bays stay productive.

Can the two guns use different connector standards?

Yes. CCS1, CCS2, CHAdeMO and GB/T DC can be combined across the two guns, and the pairing is fixed at the time of order.

Is 480kW available on the same cabinet as 120kW?

Yes. 60kW through 480kW come from the same platform family, which keeps spares and operator training common across a network.

Will it charge 800V vehicles?

The output window reaches DC1000V, so 400V and 800V architecture vehicles are both supported without a hardware change.

What network connection is needed at the site?

Any one of 4G, Ethernet or WiFi is sufficient. Many corridor sites use 4G with Ethernet as a fallback where a fixed line already exists.
