DC Charging Infrastructure
DC BusWay, PCS, SST, Protection — the DC backbone for CCS, MCS, and V2X charging (ISO 15118-2/20).
On the bus
Why dc charging infrastructure belongs on the DC BUS
High-power DC charging belongs on a DC spine when depots and fleets must scale without multi-year grid upgrades.
Integration points
- DC chargers on 800V distribution intent
- BESS buffer for peak charge windows
- OCPP 2.0.1/2.1 metering and ISO 15118-20 V2X control (design target)
- Export and import limits enforced at PCS / EMS layer
