Thermal Management Solutions Kwa Battery Systems

Palibe kukayikira kuti kutentha kwa kutentha kumakhudza kwambiri ntchito, moyo ndi chitetezo cha mabatire amphamvu.Nthawi zambiri, timayembekeza kuti batire lizigwira ntchito pamlingo wa 15 ~ 35 ℃, kuti tikwaniritse mphamvu yabwino kwambiri komanso kuyikapo, mphamvu zochulukirapo zomwe zilipo, komanso moyo wautali kwambiri (ngakhale kusungirako kutentha kochepa kumatha kukulitsa moyo wa kalendala. wa batire , koma sizikupanga nzeru kuchita otsika kutentha yosungirako ntchito, ndipo mabatire ndi ofanana kwambiri ndi anthu pankhaniyi).

Pakali pano, kasamalidwe ka matenthedwe a dongosolo la batire la mphamvu akhoza kugawidwa m'magulu anayi, kuzizira kwachilengedwe, kuzizira kwa mpweya, kuzizira kwamadzimadzi, ndi kuzizira kwachindunji.Zina mwa izo, kuziziritsa kwachilengedwe ndi njira yoyendetsera kutentha, pomwe kuziziritsa kwa mpweya, kuziziritsa kwamadzimadzi, komanso kuwongolera mwachindunji zimagwira ntchito.Kusiyana kwakukulu pakati pa atatuwa ndi kusiyana kwa sing'anga yosinthira kutentha.

· Kuzizira kwachilengedwe
Kuzizira kwaulere kulibe zida zowonjezera zosinthira kutentha.Mwachitsanzo, BYD yatengera kuzizira kwachilengedwe ku Qin, Tang, Song, E6, Tengshi ndi mitundu ina yomwe imagwiritsa ntchito ma cell a LFP.Zimamveka kuti kutsatira BYD kusinthira ku kuziziritsa kwamadzi kwamitundu yogwiritsa ntchito mabatire a ternary.

· Kuziziritsa mpweya (PTC Air Heater)
Kuziziritsa mpweya kumagwiritsa ntchito mpweya ngati njira yotumizira kutentha.Pali mitundu iwiri yofanana.Yoyamba imatchedwa passive air cooling, yomwe imagwiritsa ntchito mpweya wakunja posinthanitsa kutentha.Mtundu wachiwiri ndi kuzizira kwa mpweya, komwe kumatha kutentha kapena kuziziritsa mpweya wakunja musanalowe mu batri.M'masiku oyambirira, mitundu yambiri yamagetsi ya ku Japan ndi ku Korea inkagwiritsa ntchito njira zowonongeka ndi mpweya.

· Kuziziritsa kwamadzi
Kuziziritsa kwamadzi kumagwiritsa ntchito antifreeze (monga ethylene glycol) ngati sing'anga yotumizira kutentha.Nthawi zambiri pamakhala mitundu ingapo yosinthira kutentha mu yankho.Mwachitsanzo, VOLT ili ndi rediyeta wozungulira, wowongolera mpweya (PTC Air Conditioning), ndi dera la PTC (PTC Coolant Heater).Njira yoyendetsera batire imayankha ndikusintha ndikusintha molingana ndi njira yoyendetsera kutentha.The TESLA Model S ili ndi kuzungulira motsatizana ndi kuzirala kwa injini.Batire ikafunika kutenthedwa kutentha pang'ono, dera lozizira la mota limalumikizidwa motsatizana ndi dera loziziritsa batire, ndipo mota imatha kutentha batire.Batire yamphamvu ikakhala pa kutentha kwambiri, dera loziziritsa mota ndi dera loziziritsa batire lidzasinthidwa mofananira, ndipo makina awiri ozizirirawo amataya kutentha paokha.

· Kuzirala kwachindunji
Kuzirala kwachindunji kumagwiritsa ntchito refrigerant (gawo losintha zinthu) ngati sing'anga yosinthira kutentha.Firiji imatha kuyamwa kutentha kwakukulu panthawi yakusintha kwa gawo la gasi.Poyerekeza ndi refrigerant, kutentha kwa kutentha kumatha kuwonjezeka katatu, ndipo batire imatha kusinthidwa mwachangu.Kutentha mkati mwa dongosolo kumatengedwa.Chiwembu chozizira chachindunji chagwiritsidwa ntchito mu BMW i3.

 

Kuphatikiza pa kuzizira kozizira, ndondomeko yoyendetsera kutentha kwa batri iyenera kuganizira kusinthasintha kwa kutentha kwa mabatire onse.PACK ili ndi mazana a maselo, ndipo sensa ya kutentha sikungazindikire selo iliyonse.Mwachitsanzo, pali mabatire a 444 mu gawo la Tesla Model S, koma malo ozindikira kutentha a 2 okha amakonzedwa.Choncho, m'pofunika kuti batire ikhale yosasinthasintha momwe mungathere kudzera mu kapangidwe ka kayendetsedwe ka kutentha.Ndipo kusasinthasintha kwabwino kwa kutentha ndikofunikira kuti zizigwira ntchito mosasinthasintha monga mphamvu ya batri, moyo, ndi SOC.
