Le 25 novembre 2011, l’entreprise automobile Mazda annoncait \u00e0 Hiroshima avoir mis au point un syst\u00e8me de freinage permettant de r\u00e9g\u00e9n\u00e9rer de l’\u00e9nergie via un supercondensateur. Cette premi\u00e8re mondiale, a \u00e9t\u00e9 nomm\u00e9e \u00ab\u00a0i-ELOOP\u00a0\u00bb, acronyme de \u00ab\u00a0Intelligent Energy Loop\u00a0\u00bb. Ces syst\u00e8mes intelligents de r\u00e9g\u00e9n\u00e9ration d’\u00e9nergie b\u00e9n\u00e9ficient actuellement d’un vif inter\u00eat en raison des \u00e9conomies d’\u00e9nergie qu’ils permettent de r\u00e9aliser. i-ELOOP permet ainsi d’obtenir une r\u00e9duction substantielle de consommation de carburant de l’ordre de 10%.<\/p>\n

La nouveaut\u00e9 r\u00e9side dans la nature du composant qui au coeur du syst\u00e8me : un supercondensateur double couche \u00e0 faible r\u00e9sistance. Ce dernier permet de convertir efficacement l’\u00e9nergie cin\u00e9tique d\u00e9gag\u00e9e lors du ralentissement du v\u00e9hicule en \u00e9nergie \u00e9lectrique. L’\u00e9lectricit\u00e9 ainsi g\u00e9n\u00e9r\u00e9e est utilis\u00e9e pour alimenter le syst\u00e8me audio, la climatisation et d’autres composants \u00e9lectroniques.<\/p>\n

En sus du supercondensateur, i-ELOOP est constitu\u00e9 des composants suivants :
\n– Un alternateur \u00e0 tension variable 12-25V
\n– Un convertisseur AC\/DC<\/p>\n

i-ELOOP fonctionne sur le principe suivant \u00a0: Au moment o\u00f9 le conducteur commence \u00e0 ralentir, le syst\u00e8me r\u00e9cup\u00e8re l’\u00e9nergie cin\u00e9tique ainsi d\u00e9gag\u00e9e via l’alternateur. Cette \u00e9lectricit\u00e9 est envoy\u00e9e au supercondensateur, qui la stocke. Ce dernier, gr\u00e2ce \u00e0 sa capacit\u00e9 de charge rapide, permet de r\u00e9cup\u00e9rer l’\u00e9nergie de mani\u00e8re efficace. La tension est diminu\u00e9 par la suite \u00e0 12V par le convertisseur afin d’alimenter les diff\u00e9rents appareils \u00e9lectroniques pr\u00e9sents dans la voiture.<\/p>\n

Le supercondensateur, qui a \u00e9t\u00e9 d\u00e9velopp\u00e9 sp\u00e9cialement pour \u00eatre utilis\u00e9 dans un v\u00e9hicule, a pour particularit\u00e9 de se charger en quelques secondes.<\/p>\n

\"\"<\/p>\n

Ce syst\u00e8me de r\u00e9g\u00e9n\u00e9ration d’\u00e9nergie intelligent fonctionne conjointement au syst\u00e8me \u00ab\u00a0i-stop\u00a0\u00bb, mis au point lui aussi par Mazda. Ce syst\u00e8me d’arr\u00eat intelligent est mont\u00e9 sur les moteurs essence \u00e0 injection directe. Il \u00e9teint le moteur de la voiture lorsque celle-ci est \u00e0 l’arr\u00eat, \u00e0 un feu rouge par exemple. Le red\u00e9marrage est assur\u00e9 par combustion, c’est-\u00e0-dire que le carburant est directement inject\u00e9 dans un cylindre en compression. Le d\u00e9marreur exerce une l\u00e9g\u00e8re impulsion suppl\u00e9mentaire. Le red\u00e9marrage est alors rapide et \u00e9conome en \u00e9nergie. Ceci permet d’assurer une r\u00e9duction de consommation de carburant d’environ 10%<\/p>\n

Mazda annonce vouloir \u00e9quiper certains de ses mod\u00e8les du syst\u00e8me i-ELOOP \u00e0 partir de 2012, sans toutefois pr\u00e9ciser le(s) mod\u00e8le(s) qui en b\u00e9n\u00e9ficieront.<\/p>\n
