Several decentralised stations have been installed to charge the trucks’ batteries, including an array of battery charging systems that use a variety of technologies. Since Ottakringer had previously had good experiences with Fronius – the company equipped its subsidiary, Trinkservice GmbH, with Fronius chargers in Summer 2015 – it was an easy decision to also use charging stations in the brewery, operated via a central station with new chargers. Fronius not only used its expertise with charging technology here, it also helped to select the site and install the equipment in line with the relevant standards.
The station was designed by Fronius who then supplied 12 Selectiva battery charging systems including charging module 2000 and charging racks in Autumn 2017. The chargers impress on a technological level thanks to the Ri charging process. This is a gentle charging process where the charging characteristics are individually calculated for different batteries; this prevents overcharging, and reduces energy consumption and CO2 emissions. An external start/stop option is also available for increased safety: this function reliably prevents sparks from forming if a worker interrupts the charging process and pulls the plug. Fronius also helped find the right site with a view to achieving maximum safety, while ensuring compliance with all standards and regulations. The new station consequently had no problems attaining TÜV certification.
