Design decision
A split system separates power conversion from dispensers. A 360–1000 kW cabinet class describes an illustrative aggregate system range; the actual budget for an outlet is constrained by installed modules, other sessions, cable rating, vehicle voltage and thermal controls. Liquid cooling removes cable heat but does not make power unlimited. The tender should identify which ratings are continuous and which depend on specified conditions.
When this approach fits · Limits and alternatives
High-power shared systems may fit busy depots with diverse departures. They can be unsuitable where the grid connection, low utilization or maintenance resources cannot support them. Request module redundancy logic, cooling-fluid maintenance and leak detection, ambient-temperature derating curves, safe isolation and a staged failure test. Do not extrapolate a brochure current rating to every outlet or to all ambient conditions.
Procurement checks
- Distinguish total cabinet power from power available per charging outlet
- Confirm liquid-cooled cable ratings and ambient limits
- Model grid import and dynamic allocation under simultaneous use
Evidence to request
Define the installation country, supply, arrival and departure times, energy per session and operating constraints. Ask for an electrical design, exact configuration, test evidence and acceptance plan. Include support responsibilities and data ownership in the written scope.
