A Plug-In Hybrid‚ Blue-Angel III‚ for vehicle to grid system with a wireless grid interface
Vehicle to grid (V2G) concept is becoming
increasingly popular, but it essentially requires some form of a
power interface between the electric vehicle (EV) and the grid.
In contrast to wired power interfaces, a user-friendly and
secure wireless interfaces with no physical contacts are
preferable. This paper presents a V2G system that comprises
of a plug-in hybrid vehicle, called Blue-Angel III, and a
wireless power interface for grid integration. Blue-Angel III
uses a Li-Ion-Supercapacitor energy storage and a wireless
power interface, which is based on inductive power transfer
(IPT) technology, facilitates the power exchange between the
grid and Blue-Angel III. This paper details the structure,
control, energy storage and management, and communication
protocols of the hybrid Blue-Angel III, and discusses design
aspects of the 2kW bi-directional IPT power interface of the
proposed V2G system. Simulation results under various
conditions are presented to show that the proposed wireless
and bi-directional IPT interface is ideal for the grid integration
of Blue-Angel III and EVs.
