Fahrzeug-zu-Fahrzeug (V2V) & Microgrid-DC-Direktladung
V2Charging verwandelt Elektrofahrzeuge in mobile Energierouter. Durch bidirektionale galvanisch isolierte DAB-Gleichspannungswandler können liegengebliebene Fahrzeuge 150 kW Notstrom direkt von Spenderfahrzeugen ohne Wechselstromnetz empfangen.
V2V Direct DC Core Zonal Architecture
Central Controller: V2V Direct DC Core — Bidirectional Galvanic Controller
Zonal Control Units & TSN Ring
- Galvanically Isolated Dual Active Bridge
- Master/Slave Role Negotiation State Machine
- Peer-to-Peer Encrypted Bluetooth/PLC Link
- Zonal High-Voltage Pyro-Fuse
- Differential Residual Current Monitor
Rettung liegengebliebener Elektrofahrzeuge ohne Abschleppwagen oder Dieselgeneratoren
Direkte DC-Kopplung von Hochvoltbatterien birgt Gefahren durch Erdschleifen und Fehlerfortpflanzung. V2Charging setzt auf galvanische Trennung durch 200-kHz-Planartransformatoren und ermöglicht den Energieaustausch zwischen 400V- und 800V-Systemen mit 97,5 % Effizienz.
Core Engineering Areas
- Galvanically Isolated V2V Converter — Controlling an on-board or cable-integrated isolated converter that manages differential voltages between donor (e.g., 800V) and recipient (e.g., 400V) packs.
- Master/Slave Role Negotiation — Establishing unambiguous master (donor voltage source) and slave (recipient current sink) roles over a secure direct wireless or pilot wire link.
- P2P Energy Settlement Tokens — Generating verifiable cryptographic receipts signed by vehicle HSMs that can be redeemed or settled once cloud telematics reconnects.
