Production Concepts for Inductive Power Transfer Systems for Vehicles

Abstract

The option of wireless energy transmission in electric vehicles can become the main market driver for electric vehicles due to its distinct advantages, such as range, weight, or costs, over conventional conductive charging solutions. In addition to the great potential, which different research work and realized systems have already shown, there are new requirements for the associated production networks in the automotive industry which must be addressed at an early stage. Furthermore, no solutions currently exist for the industrial production of these components. This paper presents the main components for the feasibility of wireless power transmission in electric vehicles. In addition, the required value chains and processes for the new components of the inductive power transfer systems, and the final assembly for induction coils, which has been developed at the FAU, will be presented. These include the developing of a winding process on a 15-axis special machine, ultrasonic crimping of the litz wire ends, and vacuum potting.

“…[1][2][3] Later, more research automatically and intelligently integrated the WPT technology into the EV, and even more industry has started to test and commercialize some prototypes. [4][5][6] Wireless transmission methods are divided mainly into two types: near-field and far-field. In near-field or nonradiative technologies, energy is conveyed over relatively short distances by magnetic fields using inductive coupling [7][8][9][10] among coils, or by electric fields utilizing capacitive coupling [11,12] between metallic electrodes.…”
