ABSTRACT:
Inductive charging systems comprising improved charging wands that are coupled between a source of power and a charging port that is coupled to a battery of an electric vehicle. The improvement provided by the present invention is that the charging wand has its magnetic core molded into its body. In one embodiment, a magnetic core is directly molded into the body of the charging wand. In another embodiment, the magnetic core is molded into a plastic ring that surrounds the core which in turn is secured into the body of the charging wand. The present invention improves the assembly process for charging wands by eliminating the wide tolerance range associated with core fabrication. Molding magnetic cores into the inductive charge wand eliminates the requirement for machining the side walls of the cores. By molding the cores directly into the wand or by molding the ring around the core and securing the molded assembly into the wand results in substantial cost savings by eliminating the need to machine the cores to exact tolerances.
