Product overview
The SEC 480 kW split system moves power conversion into a service-oriented cabinet and distributes energy to remote CCS1 or NACS dispensers. Up to six charging cables and intelligent allocation let operators serve several parking positions while using installed modules more efficiently. Air- and liquid-cooled cable options support different current targets and vehicle duty cycles.
Key Product Advantages
● Up to six charging cables
One cabinet can support as many as three dual-cable dispensers for multi-vehicle operation.
● Flexible 360-480 kW platform
The power range can be matched to utility capacity and phased expansion.
● Intelligent power allocation
Available output is directed to active sessions according to vehicle demand and site rules.
● 500 A liquid-cooled option
Liquid-cooled CCS1 output supports high-current charging where the duty cycle requires it.
● Service-oriented architecture
Separating cabinet and dispensers can simplify bay layout and maintenance access.
● CCS1 and NACS
Interface choices support mixed fleets and evolving market adoption.

Cabinet-to-Dispenser Distance Matters
Long DC runs create voltage drop and heatCable length, route, conductor size and simultaneous current affect delivered voltage and losses between the cabinet and dispensers.
More dispensers do not add powerUp to three dispensers and six cables share the 480kW cabinet according to allocation rules.
Liquid cooling adds a service subsystemHigh-current liquid-cooled CCS1 requires coolant monitoring, leak checks and hose/connector inspection.
Engineering checkpoint: Freeze dispenser positions, route lengths, current duty and permissible voltage drop before releasing civil drawings.
Selection Guidance
01
Develop the system from simultaneous-vehicle demand and bay layout.
02
Select the number of dispensers, cable type and allocation logic together; adding connectors does not add cabinet power.
03
Coordinate 480 V switchgear, trench or overhead routing, voltage drop between cabinet and dispensers, service clearances, cooling airflow, impact protection, payment terminals, communications and future module capacity.
Recommended Applications
●Fleet and logistics charging depots
●Highway multi-bay charging hubs
●Rental-car and ride-hailing facilities
●Commercial vehicle staging areas
●Large retail or transport campuses
Commercial-Fleet Charging Deployment
Site-planning reference
A split 480 kW system is suited to fleet and logistics sites that need centralized power conversion with dispensers positioned around large vehicle movement zones.
Heavy-vehicle geometry: Confirm turning radii, parking depth, connector-side access and clearance for trailers before fixing dispenser positions.
Cable route: Coordinate trench or overhead routing, voltage-drop calculations, impact protection and access for future cable service.
Fleet operation: Align charging windows, depot dwell time and allocation logic so shared cabinet power supports the intended dispatch schedule.
Depot reference: Build traffic separation, charging positions, emergency-stop access and equipment service aisles into the earliest yard plan, rather than adding them after equipment delivery.
Quality-Control Focus for Fleet Infrastructure
Factory and project handover reference
A 480 kW split system depends on the complete infrastructure chain-power cabinet, dispensers, long DC routes, controls and fleet operating logic.
System traceability: Match cabinet serial identity, dispenser allocation, connector interfaces and approved configuration records.
Route and protection review: Inspect DC cable routes, mechanical protection, isolation points and emergency-stop access .
Operational verification: Record the project-required tests for power allocation, communications, charging sessions and alarm reporting.
Operation and Maintenance Reference
Use the practical field notes for routine inspection, cleaning, connector and cable checks, cooling-system care, fault recording and safe service planning. Inspect remote DC routes, dispenser impact protection, allocation logs and liquid-cooling condition where fitted.
Send the destination market, electrical supply, vehicle mix or charger architecture, communication requirements, environment and delivery plan for technical review.
Final selection and installation must follow the approved model datasheet, ordered configuration, local electrical requirements, site design and authority requirements.
