Monga gwero lalikulu lamagetsi amagetsi atsopano, mabatire amphamvu ndi ofunikira kwambiri pamagalimoto amagetsi atsopano.Panthawi yogwiritsira ntchito galimotoyo, batire idzakumana ndi zovuta komanso zosinthika zogwirira ntchito.
Pa kutentha kochepa, kukana kwamkati kwa mabatire a lithiamu-ion kudzawonjezeka ndipo mphamvu idzachepa.Zikavuta kwambiri, electrolyte imaundana ndipo batire silingathe kutulutsidwa.Kutsika kwa kutentha kwa dongosolo la batri kudzakhudzidwa kwambiri, zomwe zimapangitsa kuti magetsi azigwira ntchito.Kutentha ndi kuchepetsa kutentha.Mukamalipira magalimoto amphamvu atsopano pansi pa kutentha kochepa, BMS yamba imatenthetsa batire pa kutentha koyenera isanalipire.Ngati sichikugwiridwa bwino, zimabweretsa kuchulukira kwamagetsi nthawi yomweyo, zomwe zimapangitsa kuti pakhale gawo lalifupi lamkati, komanso utsi wina, moto kapena kuphulika kumatha kuchitika.
Pakutentha kwambiri, ngati kuwongolera kwa charger kulephera, kungayambitse chiwawa chamankhwala mkati mwa batire ndikupanga kutentha kwambiri.Ngati kutentha kumachulukana mofulumira mkati mwa batri popanda nthawi yowonongeka, batire ikhoza kutuluka, kutuluka, kusuta, ndi zina zotero. Zikavuta kwambiri, batire imawotcha mwamphamvu ndikuphulika.
Makina owongolera matenthedwe a batri (Battery Thermal Management System, BTMS) ndiye ntchito yayikulu yoyendetsera batire.Kuwongolera kutentha kwa batri makamaka kumaphatikizapo ntchito zoziziritsa, kutentha ndi kutentha mofanana.Ntchito zoziziritsa ndi zotentha zimasinthidwa makamaka kuti zitheke kutentha kwakunja kwa batire.Kutentha kwa kutentha kumagwiritsidwa ntchito kuchepetsa kusiyana kwa kutentha mkati mwa paketi ya batri ndikuletsa kuwola kofulumira chifukwa cha kutenthedwa kwa gawo lina la batri.Dongosolo lotsekera lotsekeka limapangidwa ndi sing'anga yopangira kutentha, kuyeza ndi kuwongolera, ndi zida zowongolera kutentha, kuti batire lamagetsi lizitha kugwira ntchito mkati mwa kutentha koyenera kuti likhalebe ndi momwe mungagwiritsire ntchito bwino ndikuwonetsetsa magwiridwe antchito ndi moyo wa dongosolo la batri.
1. "V" chitsanzo cha chitukuko cha njira yoyendetsera kutentha
Monga chigawo cha mphamvu ya batri yamagetsi, makina oyendetsera kutentha amapangidwanso motsatira chitsanzo cha chitukuko cha V "chitsanzo cha makampani oyendetsa galimoto. Mothandizidwa ndi zida zofananira ndi chiwerengero chachikulu cha zitsimikiziro zoyesa, motere mungathe kutero Kudalirika, chitetezo ndi moyo wautali, mtengo wachitukuko ndi dongosolo la chitsimikizo zisungidwe.
Zotsatirazi ndi chitsanzo cha "V" cha chitukuko cha kayendedwe ka kutentha.Kawirikawiri, chitsanzocho chimakhala ndi nkhwangwa ziwiri, yopingasa ndi imodzi yopingasa: chopingasa chopingasa chimakhala ndi mizere inayi yachitukuko chamtsogolo ndi mzere umodzi wotsimikiziranso, ndipo mzere waukulu ndi chitukuko chamtsogolo., poganizira kutsimikizira kotsekera kotsekeka;chigawo choyima chili ndi magawo atatu: zigawo, ma subsystems ndi machitidwe.
Kutentha kwa batri kumakhudza mwachindunji chitetezo cha batri, kotero mapangidwe ndi kafukufuku wa kayendetsedwe ka kutentha kwa batri ndi imodzi mwa ntchito zofunika kwambiri pakupanga dongosolo la batri.Mapangidwe a kasamalidwe ka matenthedwe ndi kutsimikizira kachitidwe ka batri kuyenera kuchitidwa motsatira ndondomeko yoyendetsera kasamalidwe ka batire, kasamalidwe ka matenthedwe a batri ndi mitundu ya zigawo, kusankha kwa gawo la kasamalidwe ka matenthedwe, ndi kuwunika kwa magwiridwe antchito a kasamalidwe ka matenthedwe.Pofuna kuonetsetsa magwiridwe antchito ndi chitetezo cha batri.
1. Zofunikira za kayendetsedwe ka kayendetsedwe ka kutentha.Malingana ndi magawo opangira mapangidwe monga malo ogwiritsira ntchito galimotoyo, momwe galimotoyo imagwirira ntchito, ndi zenera la kutentha kwa selo ya batri, fufuzani zofunikira kuti mufotokoze zofunikira za dongosolo la batri la kayendetsedwe ka kutentha;Zofunikira za dongosolo, malinga ndi Zofunikira kusanthula kumatsimikizira ntchito za kasamalidwe ka matenthedwe ndi zolinga zamapangidwe a dongosolo.Zolinga zopangira izi makamaka zimaphatikizapo kuwongolera kutentha kwa ma cell a batri, kusiyana kwa kutentha pakati pa maselo a batri, kugwiritsa ntchito mphamvu zamagetsi ndi mtengo wake.
2. Dongosolo la kayendetsedwe ka kutentha.Malinga ndi zofunikira zamakina, makinawa amagawidwa m'magawo ozizirira, makina otenthetsera, kutentha kwapakati ndi thermal runaway obstructin (TRo) subsystem, ndipo zofunikira za kapangidwe ka gawo lililonse zimafotokozedwa.Panthawi imodzimodziyo kusanthula kayesedwe kachitidwe kachitidwe koyambira kutsimikizira kamangidwe ka dongosolo.MongaPTC cooler heater, PTC air heater, pampu yamagetsi yamagetsi, ndi zina.
3. Kapangidwe ka subsystem, choyamba dziwani cholinga cha kamangidwe ka gawo lililonse molingana ndi kapangidwe kake, ndiyeno tsatirani njira yosankha, kamangidwe kadongosolo, kamangidwe katsatanetsatane ndi kusanthula kayeseleledwe ndi kutsimikizira kwa gawo lililonse motsatizana.
4. Mapangidwe a magawo, choyamba dziwani zolinga zamapangidwe a zigawozo malinga ndi kamangidwe ka subsystem, ndiyeno fufuzani mwatsatanetsatane ndi kusanthula kayeseleledwe.
5. Kupanga ndi kuyesa magawo, kupanga magawo, ndi kuyesa ndi kutsimikizira.
6. Kuphatikizika kwa subsystem ndi kutsimikizira, kuphatikizira kagawo kakang'ono ndi kutsimikizira mayeso.
7. Kuphatikizana kwadongosolo ndi kuyesa, kugwirizanitsa dongosolo ndi kutsimikizira kuyesa.
