Infinity driving distance in Electric Vehicle by high power Wireless Power Transfer
Wireless Power Transfer technique is very attractive technique to realize non-contact energy charging to Electric Vehicle. However, sending higher electric power with long distance is very difficult because high frequency operation is required. Our research goal is to send 10kW with 1m distance. The operating frequency is 13.56MHz. If this power transfer is realized, the running vehicle charging from not only the road but also the side wall will be possible. The cheaper energy charging system will be realized, the electric vehicle can continue to run with electric charging, the one charge driving distance will be infinity. We have already succeed to make 1kW inverter operated by 13.56MHz with over 90% efficiency, we could transfer about 1kW electric power by own made antenna, also we designed receiving rectifier to control both the impedance and the power factor.
We will transfer 3kW until 2017 and we will drive 1kW electric machine by wireless power transfer. 10kW electric power transfer will be success in 2020.
Multi-Copter Robot for infrastructure inspection
We develop the semi-auto multi-copter for infrastructure inspection, which is supported by Council for Science, Technology and Innovation (CSTI), Cross-ministerial Strategic Innovation Promotion Program (SIP), (Funding agency : JST). There are other research groups that carried out experiments using a multi-copter with camera for building inspection for years. It is hard to inspect infrastructure as the multi-copter did not stay at a fix position, which leads to distortion of images or videos taken by multi-copter. On the contrary, our semi-auto multi-copter can be control manually and autonomously equips with novel flexible electrostatic absorption devices. With flexible electrostatic absorption devices attached to this semi-auto multi-copter, proposed algorithm would be the best for close-range inspection using multi-copter as it ensure a fix position during infrastructure inspection thus improve close-range inspection results.
