Extendable and deformable carrier for a primary coil of a charging system

摘要

A subsurface mounted inductive charging coil system for electric vehicles accommodates the gap distance between primary charging coil and secondary coil on the vehicle with an extendable primary coil carrier. The system protects the primary coil when exposed by mounting on a deformable and elastic structure. By keeping the primary coil normally hidden in a deformable and elastic structure several advantages are obtained. The extendable structure is preferably a low pressure inflatable bladder or membrane in the floor for carrying, protecting, and extending the primary coil.

主权项

1. A charging station for an electric vehicle comprising:
a primary coil; and an inflatable membrane having a primary coil carrying first structure surrounding the primary coil, the inflatable membrane further having an extendable, deformable, and elastic second structure, the first structure being carried by the second structure, the charging station having a first position wherein the first structure is held beneath or substantially level to a first surface, and a second position where the first structure is moved by the second structure to be held beyond the level of the first surface, wherein the primary coil is embedded in the first structure of the inflatable membrane.
