A Probe into the Key Parameter Monitor of V2G System on Electric Vehicle Based on Wireless Power Transmission Technology

摘要

As it is both significant and practical to study how the bidirectional wireless power transmission system can be applied to the monitor control of electric vehicle under V2G environment, this paper analyzes how the bidirectional wireless power transmission system works, based on which, probes into the phase difference θ, which will influence the energy transmission direction, and ratio-voltage σ, which will influence transmission efficiency. It also promotes that coaxial installation of detection coil on secondary side and main power coil can monitor the 2 parameters in real time, and it also provides how to access the parameter. By simulation and experiments, it proved the feasibility of this method, providing a reference research approach on related studies.
