Imodzi mwaukadaulo wofunikira wamagalimoto amagetsi atsopano ndi mabatire amagetsi.Ubwino wa mabatire umatsimikizira mtengo wa magalimoto amagetsi kumbali imodzi, ndi magalimoto oyendetsa magetsi kumbali inayo.Chofunika kwambiri pakuvomera komanso kukhazikitsidwa mwachangu.
Malinga ndi mawonekedwe ogwiritsira ntchito, zofunikira ndi magawo ogwiritsira ntchito mabatire amphamvu, mitundu yofufuza ndi chitukuko cha mabatire amagetsi kunyumba ndi kunja ndi pafupifupi: mabatire a lead-acid, mabatire a nickel-cadmium, mabatire a nickel-metal hydride, mabatire a lithiamu-ion, maselo amafuta, ndi zina zambiri, zomwe zimakhudzidwa kwambiri ndikukula kwa mabatire a lithiamu-ion.
Mphamvu yopangira kutentha kwa batri
Gwero la kutentha, kutentha kwa kutentha, mphamvu ya kutentha kwa batri ndi zina zofananira za module ya batri yamagetsi zimagwirizana kwambiri ndi chikhalidwe cha batri.Kutentha kotulutsidwa ndi batri kumadalira chikhalidwe cha mankhwala, makina ndi magetsi ndi makhalidwe a batri, makamaka chikhalidwe cha electrochemical reaction.Mphamvu ya kutentha yomwe imapangidwa mumayendedwe a batri imatha kuwonetsedwa ndi kutentha kwa batri Qr;electrochemical polarization imapangitsa kuti voliyumu yeniyeni ya batire ipatukane ndi mphamvu yake yamagetsi, ndipo kutayika kwamphamvu komwe kumachitika chifukwa cha batire kumawonetsedwa ndi Qp.Kuphatikiza pa machitidwe a batri omwe akuchitika molingana ndi momwe amachitira, palinso zochitika zina.Zomwe zimachitika m'mbali zimaphatikizira kuwonongeka kwa electrolyte ndi kudzitulutsa kwa batri.The mbali anachita kutentha kwaiye mu ndondomekoyi ndi Qs.Kuonjezera apo, chifukwa batri iliyonse idzakhala ndi kukana, Joule kutentha kwa Qj kudzapangidwa pamene panopa ikudutsa.Choncho, kutentha kwathunthu kwa batri ndi chiwerengero cha kutentha kwa zinthu zotsatirazi: Qt=Qr+Qp+Qs+Qj.
Kutengera ndi kuyitanitsa kwapadera (kutulutsa), zinthu zazikulu zomwe zimapangitsa kuti batire lipange kutentha ndizosiyana.Mwachitsanzo, batire ikakhala nthawi zambiri, Qr ndiye chinthu chachikulu;ndipo m'kupita kwanthawi ya kulipiritsa kwa batire, chifukwa cha kuwonongeka kwa electrolyte, zochitika zam'mbali zimayamba kuchitika (kutentha kwapambali ndi Qs), betri ikangotsala pang'ono kunyamulidwa ndikuchulukidwa, Chomwe chimachitika ndi kuwonongeka kwa electrolyte, pomwe Qs imalamulira. .Kutentha kwa Joule Qj kumadalira pakalipano ndi kukana.Njira yolipirira yomwe imagwiritsidwa ntchito nthawi zambiri imachitika nthawi zonse, ndipo Qj ndi mtengo wake panthawiyi.Komabe, panthawi yoyambira ndi kufulumizitsa, panopa ndipamwamba kwambiri.Kwa HEV, izi ndi zofanana ndi ma amperes makumi ambiri mpaka mazana a ma amperes.Panthawiyi, Joule heat Qj ndi yaikulu kwambiri ndipo imakhala gwero lalikulu la kutentha kwa batri.
Kuchokera pamalingaliro a kuwongolera kasamalidwe ka matenthedwe, kasamalidwe ka matenthedwe (HVH) atha kugawidwa m'mitundu iwiri: yogwira ntchito komanso yopanda pake.Kuchokera pamalingaliro a sing'anga yotengera kutentha, machitidwe owongolera matenthedwe amatha kugawidwa kukhala: mpweya utakhazikika (PTC Air Heater), madzi-utakhazikika (PTC Coolant heater), ndi gawo-kusintha matenthedwe yosungirako.
Kutengera kutentha ndi chozizira (PTC Coolant Heater) ngati sing'anga, ndikofunikira kukhazikitsa kulumikizana kwa kutentha pakati pa gawo ndi sing'anga yamadzimadzi, monga jekete lamadzi, kuchititsa kutentha kosalunjika ndi kuziziritsa mwanjira ya convection ndi kutentha. conduction.Sing'anga yotengera kutentha imatha kukhala madzi, ethylene glycol kapena Refrigerant.Palinso kutengera kutentha kwachindunji pomiza chidutswacho mumadzimadzi a dielectric, koma njira zotchinjiriza ziyenera kuchitidwa kuti zisawonongeke.
Kuziziritsa kozizira kosadukiza nthawi zambiri kumagwiritsa ntchito kusinthana kwa kutentha kwa mpweya wozungulira wamadzimadzi kenako ndikulowetsa zikwa mu batire kuti musinthenso kutentha, pomwe kuziziritsa kogwira kumagwiritsa ntchito makina oziziritsa amadzimadzi apakati pa injini, kapena PTC yamagetsi yotenthetsera/kutenthetsa mafuta kuti akwaniritse kuzizirira koyamba.Kutenthetsa, kuziziritsa koyambirira kokhala ndi kanyumba ka okwera mpweya / air conditioning refrigerant-liquid medium.
Kwa machitidwe opangira matenthedwe omwe amagwiritsa ntchito mpweya ndi madzi monga sing'anga, mawonekedwe ake ndi aakulu kwambiri komanso ovuta chifukwa cha kufunikira kwa mafani, mapampu amadzi, osinthanitsa kutentha, ma heaters, mapaipi ndi zipangizo zina, komanso amagwiritsa ntchito mphamvu za batri ndikuchepetsa mphamvu ya batri. .kachulukidwe ndi kachulukidwe mphamvu.
Dongosolo lozizira la batri lamadzi limagwiritsa ntchito zoziziritsa kukhosi (50% madzi / 50% ethylene glycol) kusamutsa kutentha kwa batri kupita ku refrigerant system kudzera pa batire yozizira, kenako kupita ku chilengedwe kudzera mu condenser.Kutentha kwa madzi olowetsa batire kumatsitsidwa ndi batri N'zosavuta kufika kutentha pang'ono pambuyo pa kusinthana kwa kutentha, ndipo batri ikhoza kusinthidwa kuti igwire ntchito yabwino kwambiri yotentha kutentha;ndondomeko ya dongosolo ikuwonetsedwa mu chithunzi.Zigawo zazikulu za refrigerant system zikuphatikizapo: condenser, compressor magetsi, evaporator, valavu yowonjezera yokhala ndi valve yotseka, yoziziritsira batri (valavu yowonjezera yokhala ndi valve yotseka) ndi mapaipi oyendetsa mpweya, ndi zina zotero;Kuzungulira kwamadzi ozizira kumaphatikizapo: pampu yamadzi yamagetsi, batire (kuphatikiza mbale zoziziritsa), zoziziritsa kukhosi za batri, mapaipi amadzi, akasinja okulitsa ndi zina.
