Az ipar\u00e1gban ezek a param\u00e9terek \u00e1ltal\u00e1ban nem f\u00e9rnek meg egym\u00e1s mellett, ez\u00e9rt a kombin\u00e1ci\u00f3 komoly k\u00e9telyeket v\u00e1ltott ki. A k\u00ednai Svolt Energy vezet\u0151je, Yang Hongxin p\u00e9ld\u00e1ul \u00fagy fogalmazott, hogy a felsorolt param\u00e9terek ellentmondanak egym\u00e1snak, \u00e9s aki ismeri a technol\u00f3gi\u00e1t, tudhatja, hogy ez egy \u00e1tver\u00e9s<\/a>.<\/p>\n

\u00c1tver\u00e9s \u2013 az Svolt vez\u00e9re nem hisz a Donut csoda-akkuj\u00e1ban<\/a><\/p>\n

A Donut Lab vez\u00e9rigazgat\u00f3ja, Marko Lehtim\u00e4ki elmondta, hogy sz\u00e1m\u00edtott az eff\u00e9le reakci\u00f3kra, \u00e9s \u00e1ll\u00edt\u00e1sa szerint a v\u00e1llalat tudatosan hagyta, hogy a k\u00e9tked\u0151k el\u0151sz\u00f6r hangot kapjanak, mert \u00edgy k\u00e9s\u0151bb l\u00e1tv\u00e1nyosabb lehet a bizony\u00edt\u00e9k. Fejleszt\u00e9s\u00fck val\u00f3dis\u00e1g\u00e1nak igazol\u00e1s\u00e1ra f\u00fcggetlen vizsg\u00e1latot rendeltek meg a finn \u00e1llami kutat\u00f3int\u00e9zett\u0151l, a VTT Technical Research Centre of Finland-t\u0151l, \u00e9s elind\u00edtott\u00e1k az \u201eI Donut Believe\u201d nev\u0171 kamp\u00e1nyt, amelyben fokozatosan publik\u00e1lj\u00e1k a m\u00e9r\u00e9sek eredm\u00e9nyeit.<\/p>\n

Az els\u0151 nyilv\u00e1noss\u00e1gra hozott jelent\u00e9s egyel\u0151re csak egyetlen \u00e1ll\u00edt\u00e1st vizsg\u00e1lt: a rendk\u00edv\u00fcl gyors t\u00f6lt\u00e9st. A VTT egy 26 Ah kapacit\u00e1s\u00fa cell\u00e1t tesztelt laborat\u00f3riumi k\u00f6r\u00fclm\u00e9nyek k\u00f6z\u00f6tt, k\u00fcl\u00f6nb\u00f6z\u0151 h\u0171t\u00e9si megold\u00e1sokkal. A cell\u00e1t k\u00e9tf\u00e9le t\u00f6lt\u00e9si sebess\u00e9ggel vizsg\u00e1lt\u00e1k: 5C (130 amper mellett) \u00e9s egy extr\u00e9m, 11C (286 amperes) \u00e9rt\u00e9kkel.<\/p>\n

Az eredm\u00e9nyek szerint az akkumul\u00e1tor val\u00f3ban k\u00e9pes nagyon gyors t\u00f6lt\u00e9sre. Az extr\u00e9m, 11C tesztn\u00e9l a cella 80 sz\u00e1zal\u00e9kos t\u00f6lt\u00f6tts\u00e9get 4,5-5 perc alatt \u00e9rte el, ami nagyj\u00e1b\u00f3l megfelel a c\u00e9g egyik f\u0151 \u00edg\u00e9ret\u00e9nek. A teljes felt\u00f6lt\u00e9s ebben az esetben valamivel t\u00f6bb mint h\u00e9t percig tartott. Az alacsonyabb, 5C t\u00f6lt\u00e9si sebess\u00e9gn\u00e9l a 80 sz\u00e1zal\u00e9k k\u00f6r\u00fclbel\u00fcl 9,5 perc alatt j\u00f6tt \u00f6ssze, a teljes t\u00f6lt\u00e9s pedig 12-13,5 percig tartott a h\u0171t\u00e9st\u0151l f\u00fcgg\u0151en.<\/p>\n

A tesztek ugyanakkor r\u00e1vil\u00e1g\u00edtottak n\u00e9h\u00e1ny korl\u00e1tra is. Az egyik m\u00e9r\u00e9s sor\u00e1n, amikor a cell\u00e1t csak egyetlen h\u0171t\u0151lemezzel pr\u00f3b\u00e1lt\u00e1k t\u00f6lteni 11C sebess\u00e9ggel, a fel\u00fcleti h\u0151m\u00e9rs\u00e9klet el\u00e9rte a 90\u00b0C-os biztons\u00e1gi hat\u00e1rt, ez\u00e9rt a vizsg\u00e1latot meg kellett szak\u00edtani. R\u00f6vid h\u0171t\u00e9s ut\u00e1n folytatt\u00e1k a m\u00e9r\u00e9st. Ez arra utal, hogy a gyakorlatban valamilyen h\u0151menedzsmentre val\u00f3sz\u00edn\u0171leg sz\u00fcks\u00e9g lesz, m\u00e9g ha a v\u00e1llalat kor\u00e1bban azt is hangs\u00falyozta, hogy az akkumul\u00e1tor k\u00fcl\u00f6nleges h\u0171t\u00e9s n\u00e9lk\u00fcl is m\u0171k\u00f6dhet.<\/p>\n

Fontos az is, hogy a most publik\u00e1lt jelent\u00e9s kiz\u00e1r\u00f3lag a t\u00f6lt\u00e9si teljes\u00edtm\u00e9nyt vizsg\u00e1lta.
