En un sistema tradicional de enlace fijo, esto significa que todo el veh\u00edculo debe adaptar su rendimiento a la celda que se encuentre en peor estado. Los investigadores comparan esto con un grupo de excursionistas atados por una cuerda, donde todo el grupo debe avanzar a la velocidad del miembro m\u00e1s lento.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La nueva soluci\u00f3n de sistema, denominada \u00abbater\u00edas adaptativas\u00bb o \u00abreconfigurables\u00bb, permite modificar las conexiones entre celdas o grupos de celdas mediante interruptores y sistemas de control. Cuando una celda individual comienza a presentar problemas de rendimiento, el sistema simplemente la desconecta del circuito, permitiendo que el resto de la bater\u00eda siga funcionando. Los datos demuestran que un control \u00f3ptimo a nivel de celda individual puede prolongar la vida \u00fatil de la bater\u00eda en m\u00e1s de un 20 % en veh\u00edculos de alto voltaje. En la pr\u00e1ctica, es m\u00e1s com\u00fan utilizar el control a nivel de grupo de celdas, lo que simplifica el hardware, pero tiene un efecto ligeramente menor.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Los resultados de la simulaci\u00f3n para un coche el\u00e9ctrico con una bater\u00eda de 80 kWh y un recorrido anual de 12\u00a0000 kil\u00f3metros muestran que la necesidad de reemplazar la bater\u00eda podr\u00eda posponerse unos 14 meses. Mientras que una bater\u00eda convencional necesitar\u00eda ser reemplazada despu\u00e9s de diez a\u00f1os, la arquitectura flexible solo alcanzar\u00eda el mismo nivel de desgaste despu\u00e9s de unos once a\u00f1os. Dado que las ventajas son m\u00e1s notables con un mayor n\u00famero de celdas conectadas en serie, esta tecnolog\u00eda resulta especialmente interesante para veh\u00edculos de alto voltaje y largo alcance, as\u00ed como para camiones el\u00e9ctricos.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Un an\u00e1lisis tecnoecon\u00f3mico demuestra que la inversi\u00f3n adicional en interruptores y electr\u00f3nica de control puede recuperarse. El sistema se justifica econ\u00f3micamente si el coste adicional de producci\u00f3n no supera aproximadamente el 7 % y el veh\u00edculo recorre menos de 12\u00a0150 kil\u00f3metros al a\u00f1o.<\/p>","protected":false},"excerpt":{"rendered":"<p>Razlike v proizvodnji in neenakomerno staranje povzro\u010dajo, da nekatere celice v baterijskem sklopu hitreje izgubljajo zmogljivost.
