Design decision
Treat 200 kW as a hypothetical station-wide charging budget shared by four bays. If all four sessions received equal allocations, the arithmetic ceiling would be 50 kW per bay before other constraints. Over a 30-minute window, a constant 200 kW aggregate output would transfer at most 100 kWh before losses; four equal sessions would average at most 25 kWh each. Real charging curves and arrival times can reduce this. This is not a promise of throughput.
When this approach fits · Limits and alternatives
The example may help fleets with known dwell times; it is unsuitable as a guarantee of four simultaneous 200 kW sessions. Model arrival patterns, minimum departure energy, vehicle charging limits and queueing. Separate the charging output budget from the grid-import limit and auxiliary demand. Request a single-line drawing, a feeder study, civil works scope and a simultaneous-session acceptance test before choosing equipment.
Procurement checks
- Confirm the actual number of charging dispensers and connectors
- Verify total cabinet kW, per-bay allocation and simultaneous demand
- Review connection application, civil works and site safety
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.
