Dans un syst\u00e8me \u00e0 liaison fixe traditionnel, cela signifie que le v\u00e9hicule entier doit adapter ses performances \u00e0 la cellule la plus d\u00e9faillante. Les chercheurs comparent ce ph\u00e9nom\u00e8ne \u00e0 un groupe de randonneurs reli\u00e9s par une corde, o\u00f9 chacun doit progresser \u00e0 la vitesse du membre le plus lent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La nouvelle solution syst\u00e8me, appel\u00e9e \u00ab\u00a0batteries adaptatives\u00a0\u00bb ou \u00ab\u00a0batteries reconfigurables\u00a0\u00bb, permet de modifier les connexions entre les cellules ou groupes de cellules gr\u00e2ce \u00e0 des commutateurs et des syst\u00e8mes de contr\u00f4le. Lorsqu&#039;une cellule voit ses performances se d\u00e9grader, le syst\u00e8me la d\u00e9connecte simplement du circuit, permettant ainsi au reste de la batterie de continuer \u00e0 fonctionner. Les donn\u00e9es montrent qu&#039;un contr\u00f4le id\u00e9al au niveau de chaque cellule peut prolonger la dur\u00e9e de vie de la batterie de plus de 20\u00a0% dans les v\u00e9hicules haute tension. En pratique, le contr\u00f4le au niveau du groupe de cellules est plus souvent utilis\u00e9, ce qui simplifie le mat\u00e9riel mais a un effet l\u00e9g\u00e8rement moindre.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Les r\u00e9sultats de la mod\u00e9lisation pour une voiture \u00e9lectrique \u00e9quip\u00e9e d&#039;une batterie de 80 kWh et parcourant 12\u00a0000 kilom\u00e8tres par an montrent que le remplacement de la batterie pourrait \u00eatre repouss\u00e9 d&#039;environ 14 mois. Alors qu&#039;une batterie conventionnelle devrait \u00eatre remplac\u00e9e apr\u00e8s dix ans, cette architecture flexible n&#039;atteindrait le m\u00eame niveau d&#039;usure qu&#039;apr\u00e8s environ onze ans.
