Tras su sistema de bater\u00edas modulares Ultium, General Motors ha presentado ahora una familia de cinco unidades motrices y tres motores bajo el nombre de Ultium Drive, que propulsar\u00e1n la pr\u00f3xima generaci\u00f3n de veh\u00edculos el\u00e9ctricos del Grupo.<\/p>\n
General Motors afirma que el Ultium Drive ofrecer\u00e1 ventajas significativas sobre los anteriores veh\u00edculos el\u00e9ctricos de GM en t\u00e9rminos de rendimiento, escalabilidad, velocidad de comercializaci\u00f3n y eficiencia de producci\u00f3n. Al igual que el sistema de bater\u00edas<\/a>, se espera que Ultium Drive sea especialmente flexible, permitiendo que los componentes se instalen en una gran variedad de veh\u00edculos de distintos segmentos, desde los turismos m\u00e1s compactos hasta los grandes SUV, como el Cadillac Lyriq, o camionetas como el GMC Hummer EV.<\/p>\n Las unidades motrices deber\u00edan ser capaces de propulsar veh\u00edculos con tracci\u00f3n delantera, tracci\u00f3n trasera y tracci\u00f3n a las cuatro ruedas, esta \u00faltima a veces con un enfoque de rendimiento y otras con caracter\u00edsticas todoterreno optimizadas en funci\u00f3n de la combinaci\u00f3n. Aunque GM ha publicado algunas im\u00e1genes de las unidades motrices, a\u00fan no ha revelado detalles como la potencia, el par y la eficiencia.<\/p>\n Sin embargo, est\u00e1 claro que GM prescinde de una transmisi\u00f3n de varias velocidades, ya que las unidades combinan el motor el\u00e9ctrico con una \"transmisi\u00f3n de una sola velocidad\". Como The Verge<\/em> escribe sin ning\u00fan tipo de informaci\u00f3n de las fuentes, se supone que el cableado de Ultium Drive es significativamente reducido y m\u00e1s barato, similar al del sistema de bater\u00edas. De este modo, el sistema tambi\u00e9n deber\u00eda poder integrarse en otros modelos con mayor rapidez, y las actualizaciones de software deber\u00edan ser posibles con la arquitectura m\u00e1s sencilla. En comparaci\u00f3n con un Chevrolet Bolt, deber\u00eda ser posible reducir el cableado en un 80%.<\/p>","protected":false},"excerpt":{"rendered":" Tras su sistema de bater\u00edas modulares Ultium, General Motors ha presentado ahora una familia de cinco unidades motrices y tres motores bajo el nombre de Ultium Drive, que<\/p>","protected":false},"author":24,"featured_media":139732,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[9930],"tags":[3701,81,15713,13147,224,18870,264,19973],"class_list":["post-139731","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-automobile","tag-bev","tag-cadillac","tag-drives","tag-electric-suv","tag-general-motors","tag-gmc","tag-hummer","tag-lyriq"],"acf":{"inhalt_teil2":" General Motors has not only developed the drives but will also build them itself, including the castings and gears. This will enable GM to ramp up EV production more quickly, achieve economies of scale and flexibly adapt the production mix to demand. “As with other propulsion systems that are complex, capital intensive and contain a great deal of intellectual property, we’re always better off making them ourselves,” says Adam Kwiatkowski, GM chief engineer at Global Electrical Propulsion. “GM’s full lineup of EVs should benefit from the simultaneous engineering of Ultium Drive. Our commitment to increased vertical integration is expected to bring additional cost efficiency to the performance equation”.<\/p>\n According to Ken Morris, Vice President of Autonomous and Electric Vehicle Programs, General Motors has also benefited from its manufacturing expertise in internal combustion engines. “Making motors, transmissions, driveline components and systems are among GM’s best-known competencies, and our manufacturing expertise is proving not only transferable but advantageous as we make the transition to EVs,” Morris said.<\/p>\n As mentioned, GM is still holding back on detailed information about the Ultium Drive, but more was revealed when they introduced the battery system in March. Even at the presentation of the Cadillac Lyriq Concept in August, there were no statements about the different motor and battery variants. Marty Hogan, Lyriq’s Chief Engineer, stated at the time that the published data was inaccurate because it was still in the development phase.<\/p>\n However, with a maximum charge power of 150 kW DC, it seems clear that the Lyriq will use the 400-volt version of the Ultium battery kit. That being said, the GMC Hummer EV is likely to rely on the 800-volt system.<\/p>\n gm.com<\/a>, electrek.co<\/a>, theverge.com<\/a><\/p>\n"},"_links":{"self":[{"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/posts\/139731","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\/24"}],"replies":[{"embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/comments?post=139731"}],"version-history":[{"count":0,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/posts\/139731\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/media\/139732"}],"wp:attachment":[{"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/media?parent=139731"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/categories?post=139731"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.electrive.com\/es\/wp-json\/wp\/v2\/tags?post=139731"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
