Los investigadores de bater\u00edas de Tesla en torno a Jeff Dahn han presentado los resultados actualizados de las pruebas de sus celdas de bater\u00eda. En lugar de un mill\u00f3n de millas, ahora se espera que las bater\u00edas duren 10.000 ciclos y proporcionen potencia de tracci\u00f3n durante m\u00e1s de dos millones de millas, es decir, unos 3,2 millones de kil\u00f3metros.<\/p>\n
Electrek<\/em> se refiere a una conferencia de Jeff Dahn, publicada en YouTube<\/em>, en la que el director del Instituto Canadiense de Investigaci\u00f3n sobre Bater\u00edas present\u00f3 nuevos resultados de su trabajo sobre celdas de bater\u00eda especialmente duraderas<\/a>. Con \"aditivos especiales\", las bater\u00edas deber\u00edan poder soportar 10.000 ciclos. Suponiendo una autonom\u00eda relativamente conservadora de 350 kil\u00f3metros por ciclo (es decir, una carga completa de 0 a 100%), ser\u00edan 3,5 millones de kil\u00f3metros. Ya sean 3,2 o 3,5 millones de kil\u00f3metros: el mill\u00f3n de millas o 1,6 millones de kil\u00f3metros anunciado en septiembre de 2019 parece claramente superado.<\/p>\n Si las c\u00e9lulas se trataran con m\u00e1s cuidado, es decir, si no se utilizara la carrera de carga completa de 0 a 100%, las c\u00e9lulas deber\u00edan durar incluso 15.000 ciclos, seg\u00fan Dahn. De hecho, los gr\u00e1ficos publicados por Electrek<\/em> de la conferencia muestran una capacidad de la c\u00e9lula mucho m\u00e1s constante a lo largo de 10.000 ciclos con una carrera de carga de 0 a 80% que con una carrera de carga de 0 a 90% o de 0 a 100%.<\/p>\n Si las bater\u00edas s\u00f3lo se descargaran entre un 25% y un 50% de su capacidad, apenas mostrar\u00edan degradaci\u00f3n. Este es un rango de nivel de carga que muchos conductores de coches el\u00e9ctricos utilizan en la pr\u00e1ctica - la bater\u00eda rara vez se descarga a menos del 20%, por otro lado, rara vez se carga por encima del 80%.<\/p>","protected":false},"excerpt":{"rendered":" Los investigadores de bater\u00edas de Tesla en torno a Jeff Dahn han presentado los resultados actualizados de las pruebas de sus celdas de bater\u00eda.

He quickly answers this question himself with “yes”, and he does not only justify with the permanent use of possible robotics. For one thing, such durable batteries would not have to be recycled after use. He claims since they are as good as new, they could simply be installed in a new car after use in the first car after it has been scrapped. On the other hand, they could be used in vehicles with higher requirements, such as commercial vehicles and electric ferries.<\/p>\n In addition, batteries that do not suffer from frequent charge-discharge cycles could also be better integrated into the power grid and stabilize the grid – not only as stationary storage devices, but also in the vehicle. Tesla was rather reserved on the subject of bi-directional charging with reference to battery life. However, in May there were rumors that Tesla was preparing a bidirectional charging<\/a> function. It remains to be seen whether Dahn’s research has contributed to the possible rethink.<\/p>\n Meanwhile, there is a report from China that Tesla is planning an innovation center in Hainan province. There, research and development on technologies for batteries for electric cars and stationary energy storage systems is to be promoted.<\/p>\n electrek.co<\/a>, gasgoo.com<\/a> (innovation centre)<\/p>\n"},"_links":{"self":[{"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/posts\/141970","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/users\/22"}],"replies":[{"embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/comments?post=141970"}],"version-history":[{"count":0,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/posts\/141970\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/media\/127767"}],"wp:attachment":[{"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/media?parent=141970"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/categories?post=141970"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/tags?post=141970"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
