Kuyang'ana m'tsogolo, kubwezeredwa kwa batri kumasintha kuchokera pakuwongolera zinyalala kukhala zomangamanga zaukadaulo. Kusintha kwa magalimoto amagetsi ndi kusungirako mphamvu zowonjezera kumapanga zofuna zakuthupi zomwe sizingatheke kupyolera mu migodi. Kubwezeretsanso kumakhala kofunikira pazachuma komanso kofunika kwambiri. Chuma chozungulira cha mabatire sichikuyenda bwino-chikugwira ntchito mochulukira.
Mafunso Ofunsidwa Kawirikawiri
Ndi mabatire amtundu wanji omwe angatumizidwenso?
Pafupifupi mitundu yonse ya batri imatha kubwezeretsedwanso mwaukadaulo, ngakhale kuthekera kwachuma kumasiyanasiyana. Mabatire a lead{{1}acid (agalimoto) amapeza 99% mitengo yobwezeretsanso zinthu chifukwa chakuchulukirachulukira kwa mabatire ndi zomangamanga. Mabatire a Lithium-ion, nickel-cadmium, ndi nickel-metal hydride akugwiritsidwanso ntchito kwambiri pamene ma voliyumu akukula komanso luso laukadaulo likupita patsogolo. Mabatire amchere (AA, AAA, ndi ena.) amatha kubwezerezedwanso koma nthawi zambiri amawononga ndalama zambiri pokonza kuposa mtengo wazinthu zomwe zabwezedwa, zomwe zimapangitsa kuti mapulogalamu otolera asakhale ofala. Chofunika kwambiri ndi kukula kwake ndi mtengo wake{10}mabatire akuluakulu okhala ndi zitsulo zamtengo wapatali zomwe zimagwirizana ndi mtengo wake.
Kodi ndi batire yochuluka bwanji yomwe ingabwezedwe ndi kugwiritsidwanso ntchito?
Mitengo yochira imasiyanasiyana malinga ndi momwe batire imapangidwira komanso njira yobwezeretsanso ntchito. Lifiyamu-yobwezeretsanso ma ion amakono apeza 95-97% kuchira kwa nickel ndi cobalt, 90-92% ya lithiamu, ndi 99%+ ya aluminiyamu ndi zigawo zamkuwa. Mabatire a lead-acid amafika 99% kuchira chifukwa cha chemistry yosavuta komanso njira zokhwima. Mabatire amchere amapezanso pafupifupi 70% ya zitsulo ndi zinki. Gawo lotsala lomwe silinapezeke limapangidwa makamaka ndi zinthu za electrolyte zomwe zimawola pokonza komanso zida zazing'ono zolekanitsa pulasitiki zomwe sizingabwezedwe mwachuma.
Kodi mabatire anga akale ndingawatenge kuti kuti akabwezerenso?
Zosankha zingapo zosonkhanitsira zilipo kutengera malo ndi mtundu wa batri. Ogulitsa akuluakulu kuphatikiza Best Buy, Home Depot, Lowe's, ndi Staples amasunga -ma bin a mabatire apanyumba kwaulere. Pulogalamu ya Call2Recycle imagwiritsa ntchito 34,000+ masamba osonkhanitsira ku North America{6}onani call2recycle.org kuti muone malo. Malo ogulitsa zida zamagalimoto (AutoZone, O'Reilly, Advance Auto) amavomereza mabatire agalimoto ndipo nthawi zambiri amapereka kuchotsera kochepa. Zochitika zosonkhanitsira zinyalala zoopsa za municipal zimavomereza mitundu yonse ya batri. Kwa mabizinesi omwe ali ndi kuchuluka kwakukulu, makonzedwe achindunji ndi makampani obwezeretsanso amakhala ochita bwino.
Kodi kubwezeretsanso mabatire ndi kopindulitsa?
Inde, pamlingo wamalonda. Lifiyamu-yobwezeretsanso batire ya ion pakali pano imapanga malire a 40-60% chifukwa cha zinthu zofunika kuzibweza. Batire yamtundu wa EV imabweretsa $1,200-$1,500 muzinthu zobwezeredwa potengera mtengo wa $600-$800. Phindu likuyenda bwino monga momwe mabizinesi amakulira komanso kupita patsogolo kwaukadaulo. Komabe,-kayendetsedwe ka batire laling'ono ndi mitundu ya batire yotsika mtengo (ya alkaline) sizingakhale zopindulitsa popanda malamulo kapena thandizo. Makampaniwa asintha kuchoka pakutsata malamulo kupita ku phindu pazaka zisanu zapitazi pomwe mitengo yazinthu idakwera komanso kukonza bwino ntchito.
Kodi chimachitika ndi chiyani ngati mabatire sanagwiritsidwenso ntchito?
Mabatire otayidwa molakwika amadzetsa zovuta zachilengedwe komanso zofunikira. Zipangizo zapoizoni kuphatikizapo lead, mercury, ndi cadmium zimalowa m’nthaka ndi madzi apansi panthaka kuchokera kudzala. EPA ikuyerekeza kuti mabatire amathandizira 88% yazitsulo zolemera zapoizoni m'zinyalala zamatauni ngakhale zikuyimira zosakwana 1% ya kuchuluka kwa zinyalala. Kuopsa kwa moto kumabuka pamene mabatire a lithiamu-awoni aphwanyidwa m'magalimoto otaya zinyalala kapena ang'ambika m'malo otayiramo zinyalala, zomwe zimapangitsa moto womwe umatulutsa utsi wapoizoni. Kupitilira kuwonongeka kwa chilengedwe, kutaya mabatire kumawononga zinthu zamtengo wapatali-batire iliyonse ya EV yosakonzedwanso imayimira $1,200+ muzinthu zomwe zatayika ndipo kumafuna migodi yowonjezereka yomwe imagwirizana ndi chilengedwe.
Zofunika Kwambiri
Kubwezeretsanso mabatire kumasintha zinyalala zowopsa kukhala zopangira zopangira zofunikira, ndikukwaniritsa 95%+ mitengo yobwezeretsanso zinthu zofunika kwambiri monga cobalt, faifi tambala, ndi lithiamu kudzera munjira zapamwamba zopangira.
Mizinda itatu yolumikizidwa-chitetezo cha chilengedwe, chitetezo cha zinthu, ndi kuthekera kwachuma-zimapanga chilengedwe chokhazikika pomwe kukonzanso kumasintha kuchoka ku kufunikira kotsatira mpaka pakufunika
Malo amakono obwezereranso amatulutsa malire a 40-60% pobweza zinthu zamtengo wapatali $1,200-$1,500 pa paketi ya batri ya EV, kutsimikizira kuthekera kwachuma pazamalonda.
Makampaniwa ali pachiwopsezo ndipo ma voliyumu omwe angathe kubwezeretsedwanso akuyembekezeka kukwera kuchoka pa 200,000 kufika matani 2.5 miliyoni pofika chaka cha 2035, motsogozedwa ndi-kusiya mabatire amtundu woyamba wa EV ndi mphamvu zowongolera zomwe zimafunikira 80%+ zosonkhanitsidwa.
