Design decision
Distributed architecture or all-in-one charger.
How to compare space, serviceability, expansion and power distribution.
A two-bay urban site may favor integrated DC because each charger serves a contained location. A large depot with many outlets may benefit from central conversion and remote dispensers. But distributed systems introduce cabinet placement, cable distance, shared-failure and allocation questions that a product photograph cannot answer.

A two-bay urban site may favor integrated DC because each charger serves a contained location. A large depot with many outlets may benefit from central conversion and remote dispensers. But distributed systems introduce cabinet placement, cable distance, shared-failure and allocation questions that a product photograph cannot answer.
Decision method
Compare three dimensions, not just rated kW: civil and electrical footprint, power available per outlet under realistic concurrency, and maintenance impact when one component is unavailable. Include cable reach, ventilation, access for service and future phases. A hybrid site may use AC for long-stay bays and DC for short turnaround.
Required output
The decision record should contain a site layout, one-line electrical concept, connector map, concurrency scenario and service access plan. It should also state why the rejected architectures were less suitable for this particular operation.

Practical answers about Charging architecture. No guesswork.
Ask about your project4 questions
01When is an integrated DC architecture useful?
It can suit relatively independent charging bays where equipment and installation boundaries are straightforward. Check service space, electrical supply and expansion needs.
02When should a distributed architecture be evaluated?
Evaluate it for multiple terminals sharing centralized power. Cabinet location, cable distances, allocation limits and maintenance strategy become central design inputs.
03Does distributed charging guarantee higher availability?
No. It may introduce shared dependencies as well as flexibility. Review failure domains, isolation and service procedures for the exact architecture.
04How should AC and DC coexist on one site?
Assign them to different dwell-time and energy needs, then coordinate shared electrical limits and clear user guidance. Avoid making drivers guess which bay is appropriate.
