En una antigua central el\u00e9ctrica de carb\u00f3n de Elverlingsen, Alemania, se ha puesto en marcha un nuevo sistema estacionario de almacenamiento formado por bater\u00edas de coches el\u00e9ctricos. El proyecto ha sido desarrollado conjuntamente por Renault, la empresa tecnol\u00f3gica The Mobility House y el experto en sistemas de almacenamiento de electricidad Fenecon.<\/p>\n
El sistema estacionario de almacenamiento de bater\u00edas tiene una capacidad de almacenamiento de 3 MWh y utiliza 72 bater\u00edas que se instalaron previamente en Renault Zoes, proporcionadas por Renault, socio del proyecto. En la aplicaci\u00f3n de segunda vida, las bater\u00edas de los coches el\u00e9ctricos se utilizan como almacenamiento de energ\u00eda para la red el\u00e9ctrica. La nueva instalaci\u00f3n de almacenamiento forma parte del proyecto global de Almacenamiento Avanzado de Bater\u00edas de Renault.<\/p>\n
Para el almacenamiento estacionario, las bater\u00edas se instalaron en un contenedor de 40 pies. Cada bater\u00eda s\u00f3lo tiene asignado un inversor, ya que los 72 inversores est\u00e1n instalados en otro contenedor que se coloca encima del contenedor de bater\u00edas. Seg\u00fan Franz-Josef Feilmeier, del especialista en integraci\u00f3n Fenecon, esto tiene varias ventajas. \"Esto significa que los inversores se encuentran en una unidad t\u00e9rmica independiente de las bater\u00edas\", afirm\u00f3 Feilmeier en el acto digital de la puesta en servicio. \"Esto tambi\u00e9n significa que siempre tenemos la misma longitud de cable, ya que la distancia entre la bater\u00eda y su inversor asignado es siempre la misma\". Adem\u00e1s, esto significa que si falla uno de los emparejamientos, s\u00f3lo se ver\u00e1 afectado 1\/72 del sistema.<\/p>\n
El reto no era s\u00f3lo la disposici\u00f3n mec\u00e1nica de los componentes, sino tambi\u00e9n el software. Fenecon y The Mobility House desarrollaron un \"sistema maestro-esclavo rodante\". Para aumentar la eficacia, no todas las bater\u00edas del sistema deben utilizarse por igual, sino que debe reducirse al m\u00ednimo el n\u00famero de bater\u00edas necesarias para las necesidades del momento. Para garantizar que todas las bater\u00edas envejecen por igual, se sustituyen con regularidad.<\/p>\n
Aunque esto suena sencillo en teor\u00eda, en la pr\u00e1ctica hay algunos obst\u00e1culos que los socios tuvieron que superar en el camino. \"El reto era que la bater\u00eda era variable: como nueva o abultada con diferentes estados\", dice Feilmeier. Adem\u00e1s, si una bater\u00eda se encuentra todav\u00eda en la fase de \"piezas de recambio\", podr\u00eda retirarse del sistema y volver a instalarse en un coche si fuera necesario, ya que el sistema de control la trata con m\u00e1s delicadeza.<\/p>","protected":false},"excerpt":{"rendered":"

Robert Hienz, COO at The Mobility House, is very satisfied with the solution achieved. Because the solution is so flexible (both in terms of the software and the scalable container structure), it can serve as a blueprint, not only for further projects with stationary storage, but also for Vehicle-2-Grid solutions. “From a technological point of view, the model project is a large parking lot for our control system, with many cars that simply don’t want to leave,” says Hienz. “For the control system, it makes no difference whether the battery is permanently connected in a stationary storage facility or installed in a car and only connected temporarily.”<\/p>\n
Hienz describes the plant in Elverlingsen as a “first industrial project, but not a pilot project”. Within the framework of the Advanced Battery Storage project, the construction of a further 17 MWh has been agreed, i.e. 20 MWh in total. The turnkey solution is also to be made available to other interested parties. The partners said in a press release that “All that interested companies have to contribute is sufficient space for two 40-foot standard containers (a battery container and a transformer container) in which the 3.0 MWh system is installed on a turnkey basis, a suitable grid connection and the appropriate load profile. Optimal results are achieved by the battery storage system in industrial and commercial enterprises with a high power consumption of more than 10 GWh per year and\/or with load peaks above 500 kW.”<\/p>\n
With such a system, it should be possible to save more than 200,000 euros in electricity costs per year. On top of this, over 100,000 euros in revenue could be generated, as energy is provided on the primary control market. In addition, The Mobility House promises that the customer would not incur any costs. The financing concept is “already included, so that customers do not have to contribute anything other than sufficient space for the containers and a suitable grid connection without a building cost subsidy”.<\/p>\n
At the Digital event, the project partners did not specify when a corresponding project would be started with batteries still installed in the vehicles. The organizers clarified that they are working towards this. “It’s very important to pay attention to sustainability in electromobility. This applies not only while driving,” says Uwe Hochgeschurtz, Head of Groupe Renault in the DACH region. “We want to help ensure that the battery makes sense after life in the car and can be used for ten to twelve more years.”<\/p>\n
The Renault manager is relying primarily on research: “We have not yet explored everything that is possible with modern storage systems,” says Hochgeschurtz. “But one thing is certain: the electric car is the only car that can also lead to a reduction in CO2 emissions when it is stationary.”<\/p>\n
