  • Publication number: 20240109447
    Abstract: An integrated portable extremely fast charger (XFC) may be installed for heavy-duty off-road vehicles, such as tractors and combine harvesters. The XFC shortens the charging period of plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs) by providing >500 kW in a single charger. The proposed XFC integrates a solar farm and local energy storage system (ESS) such that the local grid only needs to provide the power gap between the vehicle battery and the local ESS during charging events, yielding a low-cost XFC installation and higher renewable energy penetration. Two design approaches for the XFC, conductive and wireless, are based on multiphase interleaved dc-dc converter circuit, permitting flexible access to electricity. Smart fault protection mechanism is also proposed to achieve high safety during charging events. The hexagonal prism charger may be integrated into the power electronic devices with a transformer, yielding a high compactness and power density.
