System Architecture Block Diagram

TOPOLOGY: 3P+N+PE GRID TO DUAL CCS2 DISPENSING

POWER ROUTING: ISOLATED MODULAR MATRIX

The architecture illustrates end-to-end electrical topology across three continuous operational stages:

STAGE 1: GRID INPUT 320–520 VAC tolerance stage featuring dual contactor galvanic isolation, EMI suppression filtering, and transient surge suppression protecting internal sub-assemblies against volatile mains instability.

STAGE 2: POWER CONVERSION MATRIX CFD direct-air cooled modular conversion matrix utilizing high-efficiency hot-swappable DC rectifiers coordinated by an intelligent HMI controller managing dynamic power allocation.

STAGE 3: DUAL CCS2 DISCHARGING Dual independent CCS2 output harnessing with certified MID-compliant DC energy metering and active cable suspension handling 250A continuous and 300A peak operation across 200–1000V bus systems.
