Centralized cabinet and remote dispensers
Power conversion modules may be grouped centrally while charging terminals are positioned to suit vehicle bays and site circulation. This can support future reconfiguration, but cable paths, losses, fault domains and electrical safety must be designed specifically.
- Plan vehicle types, bay geometry and dispenser locations first.
- Define total DC capacity, terminal count, simultaneous sessions and power allocation.
- Confirm cabinet-dispenser compatibility, cable run limits and emergency stop zoning.
Air-cooled and liquid-cooled interfaces
The supplier describes both air-cooled and liquid-cooled terminal concepts. High-current liquid-cooled cables introduce pump, coolant, leak detection and service requirements that must be covered in the operating plan.
- Do not infer MCS support from a CCS2 liquid-cooled outlet.
- Verify connector standard, permitted current and cooling design.
- Define spares, coolant service access and preventive maintenance.
Grid and civil works
A megawatt-scale project is constrained by transformer sizing, utility permissions, short-circuit assessment, harmonics, protection coordination, layout and fire-safety engineering. Storage can be evaluated but is not a substitute for site-specific calculations.
- Request a full single-line diagram and loss/efficiency assumptions.
- Define load management, commissioning and grid connection responsibilities.
- Assess meter/payment/CSMS integration and national regulations.
