Abstract
A power reception device includes: a vehicle-side resonant portion mounted on a vehicle and resonating, through an electromagnetic field, with a facility-side resonant portion provided in an external facility; and a vehicle-side support including a first support member supporting the vehicle-side resonant portion, and a second support member spaced apart from the vehicle-side resonant portion and supporting the first support member, wherein a dielectric tangent of the first support member is smaller than a dielectric tangent of the second support member.
Claims19
A power reception device, comprising:
- a vehicle-side resonant portion mounted on a vehicle and resonating, through an electromagnetic field, with a facility-side resonant portion provided in an external facility;
- and
- a vehicle-side support including a first support member supporting said vehicle-side resonant portion, and a second support member spaced apart from said vehicle-side resonant portion and supporting said first support member, wherein
- a dielectric tangent of said first support member is smaller than a dielectric tangent of said second support member.
A power transmission device, comprising:
- a facility-side resonant portion resonating, through an electromagnetic field, with a vehicle-side resonant portion mounted on a vehicle;
- and
- a facility-side support including a fourth support member supporting said facility-side resonant portion, and a fifth support member spaced apart from said facility-side resonant portion and supporting said fourth support member, wherein
- a dielectric tangent of said fourth support member is smaller than a dielectric tangent of said fifth support member.
A power transfer system, comprising:
- a power transmission device including a facility-side resonant portion provided in a facility external to a vehicle, and a facility-side support supporting said facility-side resonant portion;
- and
- a power reception device including a vehicle-side resonant portion mounted on the vehicle and resonating with said facility-side resonant portion through an electromagnetic field, and a vehicle-side support supporting said vehicle-side resonant portion, wherein
- said vehicle-side support includes a first support member supporting said vehicle-side resonant portion, and a second support member spaced apart from said vehicle-side resonant portion and supporting said first support member,
- said facility-side support includes a fourth support member supporting said facility-side resonant portion, and a fifth support member spaced apart from said facility-side resonant portion and supporting said fourth support member,
- a dielectric tangent of said first support member is smaller than a dielectric tangent of said second support member, and
- a dielectric tangent of said fourth support member is smaller than a dielectric tangent of said fifth support member.
