Scania, filial de Volkswagen, fabric\u00f3 un remolque revestido de c\u00e9lulas solares para alimentar un cami\u00f3n h\u00edbrido enchufable y est\u00e1 preparando pruebas en Suecia. En Alemania, Fraunhofer LBF tambi\u00e9n se ocup\u00f3 de los semirremolques y desarroll\u00f3 un sistema de bater\u00edas ligeras de alto voltaje para veh\u00edculos el\u00e9ctricos pesados. <\/p>\n
La nueva trainera con apoyo solar es un proyecto de investigaci\u00f3n de Scania. La empresa trabaja con el transportista sueco Ernst Express, que tambi\u00e9n colabor\u00f3 con Scania en las pruebas de la primera carretera el\u00e9ctrica del mundo con catenarias a\u00e9reas.<\/p>\n
Para la nueva prueba, Ernst Express utilizar\u00e1 un remolque de 18 metros con c\u00e9lulas solares que cubren toda la superficie a lo largo de los laterales y el techo de 140 metros cuadrados. Los socios esperan que los paneles solares generen anualmente 14.000 kWh en el pa\u00eds de origen de Scania, y las pruebas iniciales indican \"un posible ahorro de combustible del 5% al 10% en Suecia y el doble en el sur de Espa\u00f1a, rico en sol\".<\/p>\n
La agencia de innovaci\u00f3n Vinnova del gobierno sueco financia el proyecto. La empresa local Midsummer fabrica los paneles solares y la Universidad de Uppsala, que realiza investigaciones avanzadas sobre c\u00e9lulas solares m\u00e1s eficientes, y la empresa energ\u00e9tica Dalakraft tambi\u00e9n est\u00e1n a bordo. Dalakraft ayudar\u00e1 a examinar si el remolque puede inyectar electricidad a la red cuando las bater\u00edas est\u00e9n completamente cargadas y el cami\u00f3n no est\u00e9 en movimiento.<\/p>","protected":false},"excerpt":{"rendered":"

The Fraunhofer LBF project has yet to find such a real-life application. So far, research focussed on developing an energy storage unit to integrate into a semi-trailer. The unit designed by Fraunhofer LBF together with another Fraunhofer institute and the TU Darmstadt weighs just 600 kilos, including BMS and housing. 475 kilos comprise of battery material as the team integrated 10,000 cells in form factor 18650 with lithium metal oxide cathodes. The resulting energy storage has a total capacity of 100-kilowatt hours and a voltage range from 590 to 670 volts.<\/p>\n
To combine that many cells, they developed unique current connectors using electrolytically nickel-plated cold rolled strip and then welded them to the cells that then formed modules of 240 cells each.<\/p>\n
Adding other lightweight technologies such as sandwich structures for the casing, Fraunhofer LBF says they achieved a ratio of 0.8 between cell mass and total weight. “With such an ultra-lightweight construction solution for a high-voltage energy storage system, concepts such as the evTrailer are possible and develop perspectives for achieving the CO2 reduction targets in freight transport,” explains R\u00fcdiger Heim, who supervised the joint research project at Fraunhofer LBF.<\/p>\n
The researchers defined long-term use as 700,000 kilometres and determined that the discharge had to be limited to 50 per cent of the maximum possible capacity given the studied degradation. In-use applications have yet to surface.<\/p>\n
