Patent ID: 8796990

Claim:
A system for charging a rechargeable battery, comprising: a power transformer including a first core, the first core including first, second, and third pole surface areas; and a second core, the second core including first, second, and third pole surface areas, and wherein the first core and the second core are separated by first, second, and third air gaps, the first air gap separating the first pole surface area of the first core and the first pole surface area of the second core, the second air gap separating the second pole surface area of the first core and the second pole surface area of the second core, and the third air gap separating the third pole surface area of the first core and the third pole surface area of the second core; and a semi-permeable magnetic membrane comprising an epoxy binder and a ferromagnetic material embedded within the epoxy binder, wherein the semi-permeable magnetic membrane coats each of the first, second, and third poles on the first core, and the semi-permeable magnetic membrane coats each of the first, second, and third poles on the second core, the first core is electrically connected to a primary voltage source, and the second core is located apart from the first core until recharging occurs and further is electrically connected to the rechargeable battery.
