Madera ambiri onyamula mphamvu zambiri okhala ndi kabati yonyamula katundu, wokulirapo, wolemetsa, wokwera mtengo, woyika movutikira ndi zina zotero.EAK super madzi utakhazikika resistor kuti ikuthandizeni kuthetsa mphamvu zazikulu, zazing'ono, zotsika mtengo ndi zabwino zina zambiri.
Kuonjezera apo, m'magalimoto amagetsi ndi osakanizidwa, kubwezeretsanso mphamvu ndi njira yabwino kwambiri yopezera mphamvu mwa kulipiritsa batri, koma nthawi zina imapeza mphamvu zambiri kuposa momwe batire ingagwiritsire ntchito.Izi ndizowona makamaka pamagalimoto akuluakulu monga magalimoto, mabasi ndi makina otuluka m'misewu, Magalimotowa amayamba kutsika nthawi yayitali mabatire akamangika.M'malo motumiza zowonjezera zamakono ku batri, njira yothetsera vutoli ndikuitumiza ku brake resistor kapena seti ya ma brake resistors omwe amagwiritsa ntchito kukana kuti asinthe mphamvu ya magetsi kukhala kutentha, ndi kutulutsa kutentha mu mpweya wozungulira.Cholinga chachikulu cha dongosololi ndi kusunga mphamvu ya braking pamene kuteteza batri kuti zisawonongeke panthawi yobwezeretsanso, ndipo kubwezeretsa mphamvu ndikulimbikitsanso kothandiza. "Dongosolo likangotsegulidwa, pali njira ziwiri zogwiritsira ntchito kutentha," EAK ikutero.“Chimodzi ndicho kutenthetsa batire.M'nyengo yozizira, batire ikhoza kuzizira kwambiri kuti iwononge, koma dongosolo likhoza kulepheretsa kuti izi zisachitike.Mutha kugwiritsanso ntchito kutenthetsa nyumbayo. ”
Mu zaka 15-20, ngati n'kotheka, braking adzakhala regenerative, osati makina: izi zimapanga mwayi kusunga ndi regenerative braking mphamvu, osati kungotaya ngati kutentha zinyalala.Mphamvu zimatha kusungidwa mu batire yagalimoto kapena panjira yothandizira, monga flywheel kapena supercapacitor.
M'magalimoto amagetsi, kuthekera kwa DBR kuyamwa ndikuwongolera mphamvu kumathandizira pakubweza mabuleki.Regenerative braking imagwiritsa ntchito mphamvu zochulukirapo za kinetic kuti azilipiritsa batire lagalimoto yamagetsi.
Zimachita izi chifukwa ma motors omwe ali m'galimoto yamagetsi amatha kuyenda mbali ziwiri: imodzi imagwiritsa ntchito magetsi kuyendetsa mawilo ndi kuyendetsa galimotoyo, ndipo ina imagwiritsa ntchito mphamvu zambiri za kinetic kuti azilipiritsa batire.Pamene dalaivala akukweza phazi lake kuchoka pa pedal pedal ndi kukanikizira brake, galimotoyo imakana kuyenda kwa galimotoyo, "Imasintha njira," ndipo imayamba kulowetsanso mphamvu mu batri. kutaya mphamvu ya kinetic mu mphamvu yosungidwa mu batri.
Pafupifupi, mabuleki osinthika amakhala pakati pa 60% ndi 70% moyenera, kutanthauza kuti pafupifupi magawo awiri mwa atatu a mphamvu ya kinetic yomwe idatayika panthawi ya braking imatha kusungidwa ndikusungidwa mu mabatire a EV kuti ipititse patsogolo, izi zimathandizira kwambiri kuyendetsa bwino kwagalimoto ndikuwonjezera moyo wa batri. .
Komabe, regenerative braking sangathe ntchito yekha.DBR ndiyofunikira kuti njirayi ikhale yotetezeka komanso yothandiza.Ngati batire ya galimotoyo ili kale yodzaza kapena dongosolo likulephera, mphamvu yowonjezera ilibe malo othawirako, zomwe zingayambitse dongosolo lonse la braking.Chifukwa chake, DBR imayikidwa kuti iwononge mphamvu zochulukirapo izi, zomwe sizoyenera kuwongolera mabuleki, ndikuzichotsa motetezeka ngati kutentha.
Muzitsulo zowonongeka ndi madzi, kutentha kumeneku kumatenthetsa madzi, omwe amatha kugwiritsidwa ntchito kwinakwake m'galimoto kuti atenthetse kabati ya galimotoyo kapena kutenthetsa batri palokha, chifukwa mphamvu ya batri imagwirizana mwachindunji ndi kutentha kwake.
Katundu Wolemera
DBR siyofunika kokha mu dongosolo lonse la EV braking.Pankhani yama braking systems yamagetsi olemera kwambiri (HGV) , kugwiritsa ntchito kwawo kumawonjezera wosanjikiza wina.
Magalimoto onyamula katundu amaphwanya mosiyana ndi magalimoto chifukwa sadalira mabuleki kuti achepetse liwiro.M'malo mwake, amagwiritsa ntchito mabuleki othandizira kapena endurance omwe amachedwetsa galimoto limodzi ndi mabuleki amsewu.
Satenthedwa msanga pakatsika kwa nthawi yayitali ndipo amachepetsa chiopsezo cha kuwola kwa mabuleki kapena kulephera kwa mabuleki mumsewu.
M'magalimoto olemera amagetsi, mabuleki amatsitsimutsanso, kuchepetsa kuvala kwa mabuleki amsewu ndikuwonjezera moyo wa batri ndi mitundu.
Komabe, izi zitha kukhala zowopsa ngati makinawo akulephera kapena phukusi la batri silinaperekedwe mokwanira.Gwiritsani ntchito DBR kuti muwononge mphamvu zambiri ngati kutentha kuti muteteze chitetezo cha braking system.
Tsogolo la haidrojeni
Komabe, DBR sikuti imangogwira ntchito pakuwotcha.Tiyeneranso kuganizira momwe angakhalire ndi zotsatira zabwino pa msika womwe ukukula wa magalimoto amagetsi a hydrogen fuel cell (FCEV) .Ngakhale kuti FCEV sichikhoza kufalikira kufalikira, teknoloji ilipo, ndipo ndithudi ili ndi chiyembekezo cha nthawi yaitali.
FCEV imayendetsedwa ndi Proton exchange membrane fuel cell.FCEV imaphatikiza mafuta a haidrojeni ndi mpweya ndikuipopera mu selo lamafuta kuti isinthe haidrojeni kukhala magetsi.Ikalowa mkati mwa cell cell, imayambitsa kutulutsa kwa ma electron ku hydrogen.Kenako ma elekitironi amatulutsa magetsi, amene amasungidwa m’mabatire ang’onoang’ono opangira magetsi m’galimoto.
Ngati haidrojeni yomwe imagwiritsidwa ntchito kuwapatsa mphamvu imapangidwa kuchokera kumagetsi kuchokera kuzinthu zongowonjezwdwa, zotsatira zake zimakhala njira yoyendera yopanda mpweya.
Mapeto okhawo opangidwa ndi maselo amafuta ndi magetsi, madzi ndi kutentha, ndipo mpweya wokhawo ndi mpweya wamadzi ndi mpweya, zomwe zimapangitsa kuti zigwirizane ndi kukhazikitsidwa kwa magalimoto amagetsi.Komabe, ali ndi zovuta zina zogwirira ntchito.
Ma cell amafuta sangathe kugwira ntchito molemera kwambiri kwa nthawi yayitali, zomwe zingayambitse mavuto pakuthamanga kapena kutsika mwachangu.
Kafukufuku wokhudza ntchito ya selo yamafuta akuwonetsa kuti mafuta akayamba kufulumira, mphamvu yotulutsa mphamvu ya cell cell imawonjezeka pang'onopang'ono mpaka pamlingo wina, koma kenako imayamba kugwedezeka ndikuchepa, ngakhale liwiro limakhala lofanana.Kutulutsa mphamvu kosadalirika kumeneku kumabweretsa zovuta kwa opanga magalimoto.
Njira yothetsera vutoli ndikuyika ma cell amafuta kuti akwaniritse zofunikira zamphamvu kuposa momwe zimafunikira.Mwachitsanzo, ngati FCEV ikufuna mphamvu ya 100 kilowatts (kW), kukhazikitsa mafuta a 120 kW kudzaonetsetsa kuti mphamvu yamagetsi yofunikira imakhalapo nthawi zonse, ngakhale mphamvu ya selo ya mafuta itachepa.
Kusankha yankho kumafuna kuti DBR ichotse mphamvu zochulukirapo pochita ntchito za "Load gulu" pomwe sizikufunika.
Mwa kuyamwa mphamvu zochulukirapo, DBR imatha kuteteza makina amagetsi a FCEV ndikuwathandiza kuti athe kuyankha bwino pakufuna kwamphamvu kwambiri ndikufulumizitsa ndikutsika mwachangu popanda kusunga mphamvu zochulukirapo mu batri.
Opanga ma automaker ayenera kuganizira zinthu zingapo zofunika posankha DBR pamagalimoto amagetsi.Kwa magalimoto onse oyendetsa magetsi (kaya batire kapena mafuta amafuta) , kupanga zigawozo kukhala zopepuka komanso zophatikizika momwe ndingathere ndikofunikira kwambiri pamapangidwe.
Ndi njira yosinthira, kutanthauza kuti mpaka mayunitsi asanu atha kuphatikizidwa muchigawo chimodzi kuti akwaniritse zofunikira zamphamvu za 125kW.
Pogwiritsa ntchito njira zowonongeka ndi madzi, kutentha kumatha kutayidwa bwino popanda kufunikira kwa zigawo zina, monga mafani, monga oletsa mpweya wozizira.
