车对车 (V2V) 双向极速互充与直流微电网直连能量路由系统
V2Charging 将软件定义电动汽车升维为高弹性移动微电网能量路由器。通过在车端深度集成基于碳化硅的双向高频电气隔离双主动桥 (DAB) DC-DC 变换器,电量耗尽抛锚的纯电车辆无需依赖传统交流电网,即可直接从救援车或移动充电宝获得高达 150kW 的直流极速救援能量注入。
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
