NF high voltage PTC coolant heater imathandizira kuthetsa ululu wa kutentha kwa batri

Kwa batri yamagetsi yamagalimoto amagetsi, kutentha kochepa, ntchito ya lithiamu ion imachepetsedwa kwambiri, ndipo nthawi yomweyo, kukhuthala kwa electrolyte kumawonjezeka kwambiri.Zotsatira zake, ntchito ya batri idzachepa kwambiri, ndipo idzakhudzanso moyo wa batri.Choncho, kutentha batire paketi n'kofunika kwambiri.Pakalipano, magalimoto ambiri amagetsi atsopano amangokhala ndi makina oziziritsa batire, pamene akunyalanyaza makina otenthetsera.

Pakalipano, njira yotentha ya batire yodziwika bwino imakhala makamaka kutentha mpope ndiPtc Coolant Heater.Malinga ndi ma OEM, zosankha zosiyanasiyana ndizosiyana: Mwachitsanzo, paketi ya batri ya Tesla Model S imatenthedwa ndi waya wokana ndikugwiritsa ntchito mphamvu zambiri.Pofuna kupulumutsa mphamvu zamagetsi zamtengo wapatali, Tesla analetsa kukana pa Model 3. Mawaya amatenthedwa, omwe amawotcha batri ndi kutentha kwa zinyalala kuchokera kumagetsi amagetsi ndi magetsi.Kutentha kwa batri pogwiritsa ntchito 50% madzi + 50% ethylene glycol monga sing'anga ikulandiridwa ndi opanga magalimoto akuluakulu, ndipo mapulojekiti ambiri atsopano ali pakukonzekera asanapangidwe.

Palinso zitsanzo zomwe zimagwiritsa ntchito kutentha kwa pampu yotentha.Komabe, kutentha kozungulira kukakhala kochepa, pampu yotentha imakhala ndi mphamvu yochepetsera kutentha ndipo sichikhoza kutentha mofulumira.Chifukwa chake, pakalipano, kwa OEMs, njira yotenthetsera yamadzimadzi yamagetsi yayikulu ndiye njira yothetsera kupweteka kwa kutentha kwa batri m'nyengo yozizira kusankha koyamba.

NF high pressure PTC cooler heater (HVCH)

Chatsopanochotenthetsera chozizira kwambiri cha PTCimakhala ndi ma ultra-compact modular design yokhala ndi mphamvu zotentha kwambiri.Kutsika kwamafuta otsika komanso kuchita bwino kwambiri ndi nthawi yoyankha mwachangu kumapereka kutentha kwa kabati kwa magalimoto osakanizidwa ndi magetsi.Kukula kwake kwa phukusi ndi kulemera kwake kumachepetsedwa, ndipo moyo wake wautumiki ndi wautali: filimu yakumbuyo yotentha yotentha imakhala ndi moyo wautumiki wa maola 15,000 kapena kuposerapo;magetsi amasinthasintha kwambiri ndipo amapangidwa ndi chosinthira choziziritsa kuzizira;Kuthamanga kwa 800 V kumapezekanso ngati njira.

Mu Seputembara 2018, kudalira luso lake lolemera pantchito yamagetsi owongolera matenthedwe agalimoto yamagetsi, NF idalandira dongosolo lalikulu la zotenthetsera zamadzimadzi kuchokera kwa wopanga magalimoto otsogola ku Europe komanso wopanga magalimoto akuluakulu aku Asia.Dongosololi lidayamba kale kupanga mu 2020.
