plants. As a turnkey partner the company, located in central Germany, provides bespoke production systems for customers in the automotive and aviation industries. As well as body shell production lines, FFT also implements automated maintenance concepts and manufacturing cells used in final product assembly. As part of its turnkey approach, FFT offers its customers a complete and coordinated solution, comprised of the production plant and all associated materials handling. To expand its range of services and meet

customer demands for complete flexible automation solutions for the logistical interlinking of production plants, the company developed their FFTigv automated guided vehicle (AGV) system. FFT’s customers expect a complete production environment from a single source that perfectly meets their requirements, which is why they decided to produce an AGV system of their own.
HIGH CHARGING POWER FOR LARGE LOADS
The FFTigv is fitted as standard with Wiferion by PULS charging technology. The tight cycle times in body shell construction and heavily staggered cycles, were key drivers for choosing wireless charging as the power supply. FFT already has several thousand Wiferion by PULS etaLINK charging systems being used successfully so it was natural to use it in the new AGV system. The particular challenge was that because of the heavy goods being transported, the robots needed to be charged with high currents in just a short time. Wiferion by PULS therefore developed an energy system comprising high-performance batteries and chargers to meet the new requirements perfectly. The FFTigv has two etaLINK 3000 fast charging systems that,

connected in parallel, produce a charging power of 6 kW and supply the batteries with energy at a charging rate of 2 C.
IN USE AROUND THE CLOCK FFT stands for Flexible Fertigungstechnik (Flexible Manufacturing Technology). The flexibility of the etaLINK fast charging system was crucial. The charging points can be positioned at almost any frequently used
location in a warehouse either horizontally or vertically. Once a robot has moved alongside or over a charging point, the power transfer starts automatically, and charging is at full power after just a second. in-process charging of the AGVs avoids having charging breaks and unproductive travel times to stationary charging stations, ensuring availability of the vehicles around the clock. This ensures the deployment of high- productivity manufacturing lines, as in the BMW Group factory in Leipzig. A further reason for FFT to select a Wiferion
etaLINK Wireless charging system is its robustness, ensuring their reputation for outstanding system reliability is essential. High- maintenance technologies are avoided and being encapsulated the etaLINK does not use any mechanical components making it 100 per cent maintenance-free. Worldwide, 130 etaLINK charging systems are in use in FFT’s AGVs and they are currently developing a new manufacturing plant with a double-digit number of robots for the BMW Group’s Leipzig plant. Wiferion by PULS inductive battery charging
systems enable the continuous operation of AGVs and AMRs. Their innovative “in-process charging” allows the vehicles to be supplied with energy efficiently and fully automatically, without contact and without the vehicles having to interrupt their transport for charging breaks.
