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.
