Vehicle-to-Vehicle (V2V) & Microgrid DC Direct Charging

V2Charging transforms software-defined electric vehicles into mobile energy routers. By integrating bidirectional high-frequency isolated Dual-Active-Bridge (DAB) DC-DC converters, stranded EVs can receive emergency 150kW power directly from donor vehicles or mobile rescue battery packs without an AC grid connection.

Rescuing Stranded EVs Without Tow Trucks or Diesel Generators

Direct DC-DC coupling between high-voltage vehicle traction packs introduces circulating ground loops and fault propagation hazards. V2Charging enforces galvanic isolation through high-frequency planar transformers operating at 200kHz, allowing differing battery pack voltages (e.g., 400V to 800V) to exchange power with 97.5% efficiency.

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.
