etaLINK3000: Blue Inductive has launched an inductive fast charging system for AGVs, mobile robots and forklift trucks

Contactless, highly flexible energy supply solutions for the automation of logistics processes

Freiburg, 18.02.2019-After successful field tests with well-known clients in the automotive and logistics industry, Blue Inductive started series production of its etaLINK3000 inductive fast charging system in 2018. The contactless, flexible energy solution enables the “in process charging” of driverless transport vehicles, mobile robots and forklift trucks. The Freiburg-based company’s patented technology not only supports the automation and flexibility of logistics processes, but also trailblazes a 100 percent autonomous AGV operation. The products can be seen at the Blue Inductive C40 booth in Hall 10 for LogiMAT 2019 (February 19-21, Stuttgart).

etaLINK3000 is a contactless, flexible fast charging system for a variety of applications in production and logistics. The system consists of a stationary transmitter and, on the side of the vehicle, a receiving device. For energy transmission, the etaLINK technology developed and patented by Blue Inductive uses the principle of magnetic induction. With innovations in circuit design, control technology and coil construction, etaLINK3000 is the first contactless, extremely compact charging system with an efficiency of over 90 percent on the market. After successful field tests, series production started in 2018.

The charging systems have a power of 3kW with a maximum charging current of 60A and can be easily integrated into different logistics and production facilities according to the plug & play principle. Thanks to the very short initialization time from < 1 second to reaching full power, etaLINK3000 enables the so-called "in process charging" of industrial vehicles, mobile robots and forklift trucks in a very efficient way. For example, the towing vehicle of a route train can be quickly and effectively loaded during a stopover at a supermarket. The process-integrated store minimizes store breaks and thus increases fleet efficiency and utilization. The charging stations can be used by a wide variety of vehicles, whether driverless transport systems, forklift vehicles or smaller electric vehicles. An important factor in the automation of entire fleets.

By eliminating plug and grinding contacts in combination with modern lithium-based batteries, etaLINK3000 offers increased safety compared to previous charging systems and is completely maintenance-free. Another advantage: The charging systems can be seamlessly integrated into predictive maintenance concepts. To do this, the charging system has real-time data collection. It monitors operating conditions and the ageing behaviour of batteries and transmits indicators of possible disturbances via the CAN bus to fleet management. Unexpected vehicle failures with possible gridlock of an entire production fleet and the associated devastating follow-up costs can be avoided. Increased vehicle availability can reduce fleet size by up to 30 percent.

EtaLink3000 meets the latest requirements for a fully automated, maintenance-free energy supply and helps to increase the reliability and process efficiency of logistics and production facilities. Following the start of the 3kW system, Blue Inductive engineers are already working on the development of a 12kW system, the launch of which is planned for the end of 2019.
