En este contexto, los ingenieros de automoci\u00f3n suelen debatir sobre&nbsp;<strong>Arquitecturas de alimentaci\u00f3n de 400 V y 800 V<\/strong>, los cuales definen la tensi\u00f3n de funcionamiento de los principales componentes de alta tensi\u00f3n, entre ellos el paquete de bater\u00edas, la electr\u00f3nica de potencia, <a href=\"https:\/\/www.brogenmotors.com\/es\/product\/electric-vehicle-motors\/\" target=\"_blank\" rel=\"noopener\">motor el\u00e9ctrico<\/a>, y <a href=\"https:\/\/www.brogenmotors.com\/es\/product-category\/auxiliary-system\/\" target=\"_blank\" rel=\"noopener\">sistema de carga<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Es importante destacar que un\u00a0<strong>La arquitectura de 800 V no hace referencia a un \u00fanico componente<\/strong>, sino m\u00e1s bien un sistema completo cuyo rango de funcionamiento nominal suele situarse entre\u00a0<strong>550 V\u2013930 V<\/strong>. La forma m\u00e1s directa de determinar si un veh\u00edculo cumple los requisitos para considerarse una plataforma de 800 V es a trav\u00e9s de su\u00a0<strong>tensi\u00f3n nominal de la bater\u00eda<\/strong>, que suele implementarse como un\u00a0<strong>bater\u00edas de alta tensi\u00f3n<\/strong>\u00a0dise\u00f1ado para una carga ultrarr\u00e1pida y una mayor eficiencia.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"project-background\"><strong>Niveles de tensi\u00f3n est\u00e1ndar en los veh\u00edculos el\u00e9ctricos<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Los veh\u00edculos de combustible tradicionales funcionan con sistemas de 12 V para alimentar los controles electr\u00f3nicos b\u00e1sicos. Lo mismo ocurre con los veh\u00edculos el\u00e9ctricos: las bater\u00edas auxiliares de plomo-\u00e1cido o de litio de 12 V siguen alimentando la iluminaci\u00f3n, el sistema de infoentretenimiento y los accesorios de baja tensi\u00f3n.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sin embargo, los sistemas de propulsi\u00f3n dependen de grandes&nbsp;<strong>bater\u00edas de iones de litio de alta tensi\u00f3n<\/strong>, compuesto por miles de c\u00e9lulas individuales, que suele funcionar a:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Veh\u00edculos h\u00edbridos:<\/strong>&nbsp;100

alta:<\/strong>&nbsp;~600 V\u2013800 V<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Por ejemplo:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Tesla Model 3 \/ Model X: ~350

suele agrupar todos los sistemas con tensiones de entre ~350 y 450 V en la&nbsp;<strong>Categor\u00eda de arquitectura de 400 V<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"
