Kuwunika Kwa Dongosolo Lamatenthedwe Amagetsi a Mphamvu ya Battery Heat Transfer Medium

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 pakuwona kuwongolera kasamalidwe ka matenthedwe, machitidwe owongolera matenthedwe amatha kugawidwa m'mitundu iwiri: yogwira ntchito komanso yopanda pake.Kuchokera pamalingaliro a sing'anga yotumizira kutentha, machitidwe oyendetsera kutentha amatha kugawidwa kukhala: mpweya woziziritsidwa, woziziritsidwa ndi madzi, ndi kusungirako kutentha kwa gawo.

Kuwongolera kutentha ndi mpweya ngati sing'anga yotumizira kutentha

Sing'anga yotumizira kutentha imakhudza kwambiri ntchito ndi mtengo wa kayendetsedwe ka kutentha.Kugwiritsiridwa ntchito kwa mpweya monga sing'anga yotumizira kutentha ndiko kuyambitsa mwachindunji mpweya kotero kuti umayenda kudzera mu module ya batri kuti ukwaniritse cholinga cha kutentha kwa kutentha.Nthawi zambiri, mafani, mpweya wolowera ndi kutulutsa ndi zinthu zina zimafunikira.
Malinga ndi magwero osiyanasiyana otengera mpweya, nthawi zambiri pamakhala mitundu iyi:
1 Kuzizira kwapang'onopang'ono ndi mpweya wabwino wakunja
2. Kuzizira kwapang'onopang'ono / kutentha kwa chipinda chokwera mpweya mpweya wabwino
3. Kuziziritsa/kutenthetsa mpweya wakunja kapena m'chipinda cha anthu okwera
Kapangidwe kachitidwe kachitidwe kamakhala kosavuta ndipo kamagwiritsa ntchito malo omwe alipo.Mwachitsanzo, ngati batire ikufunika kutenthedwa m'nyengo yozizira, malo otentha m'chipinda chokwera angagwiritsidwe ntchito pokoka mpweya.Ngati kutentha kwa batire kuli kokwera kwambiri poyendetsa galimoto ndipo kuziziritsa kwa mpweya m’chipinda cha anthu okwera sikuli bwino, mpweya wozizira wochokera kunja ukhoza kuukoka kuti uzizizire.

Kwa dongosolo logwira ntchito, dongosolo lapadera liyenera kukhazikitsidwa kuti lipereke ntchito zowotcha kapena zoziziritsa kukhosi ndikudziwongolera paokha malinga ndi momwe batire ilili, zomwe zimawonjezeranso kugwiritsa ntchito mphamvu ndi mtengo wagalimoto.Kusankhidwa kwa machitidwe osiyanasiyana makamaka kumadalira zofunikira pakugwiritsa ntchito batri.

Kuwongolera kotentha ndi madzi monga sing'anga yotumizira kutentha

Pakutengera kutentha ndi madzi ngati sing'anga, ndikofunikira kukhazikitsa kulumikizana kwa kutentha pakati pa gawo ndi sing'anga yamadzi, monga jekete lamadzi, kuchititsa kutentha kosalunjika ndi kuziziritsa mu mawonekedwe a convection ndi kutentha ma 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 kwamadzi pang'onopang'ono 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, kapena kutentha kwamagetsi/kutenthetsa mafuta kuti akwaniritse kuzizirira koyamba.Kutenthetsa, kuziziritsa koyambirira kokhala ndi kanyumba ka okwera mpweya / air conditioning refrigerant-liquid medium.
The matenthedwe kasamalidwe dongosolo mpweya ndi madzi monga sing'anga amafuna mafani, mapampu madzi, exchanger kutentha, heaters (PTC air heater), mapaipi ndi zina zowonjezera kuti mapangidwewo akhale aakulu kwambiri komanso ovuta, komanso amadya mphamvu ya batri, gulu Kuchuluka kwa mphamvu ndi mphamvu za batri zimatsitsidwa.
(PTC coolantchotenthetsera) Makina oziziritsa amadzi ozizira amadzi amagwiritsa ntchito zoziziritsa kukhosi (50% madzi / 50% ethylene glycol) kutumiza kutentha kuchokera ku batri kupita ku air-conditioning refrigerant system kudzera mu batire yozizira, kenako kupita ku chilengedwe kudzera mu condenser.Kutentha kwa madzi otumizidwa kunja kumakhala kosavuta kufika kutentha kochepa pambuyo pa kusinthanitsa kwa kutentha ndi batire yozizira, ndipo batri ikhoza kusinthidwa kuti igwire ntchito pa kutentha kwabwino kwambiri;ndondomeko ya dongosolo ikuwonetsedwa mu chithunzi.Zigawo zazikulu za refrigerant system zikuphatikizapo: condenser, compressor magetsi, evaporator, valavu yowonjezera ndi valve yoyimitsa, batire yozizira (valavu yowonjezera ndi valve yoyimitsa) ndi mapaipi oyendetsa mpweya, ndi zina zotero;Kuzungulira kwa madzi ozizira kumaphatikizapo:pompa madzi amagetsi, batire (kuphatikiza mbale zoziziritsira), zoziziritsira batire, mapaipi amadzi, matanki okulitsa ndi zina.
