Nekuwedzera kwekutengesa nekuva muridzi wemotokari itsva dzinoshandisa simba, njodzi dzemoto dzemotokari itsva dzinoshandisa simba dzinoitikawo nguva nenguva. Kugadzira sisitimu yekutonga kupisa idambudziko guru rinotadzisa kugadzirwa kwemotokari itsva dzinoshandisa simba. Kugadzira sisitimu yekutonga kupisa yakasimba uye inoshanda zvakakosha pakuvandudza kuchengetedzeka kwemotokari itsva dzinoshandisa simba.
Kutevedzera thermal modelling yebhatiri reLi-ion ndiyo hwaro hwekutonga kwekupisa kwebhatiri reLi-ion. Pakati pazvo, kutevedzera thermal transfer modelling uye kutevedzera thermal generation modelling zvinhu zviviri zvakakosha zve lithium-ion battery thermal modelling. Muzvidzidzo zviripo zvekuenzanisa thermal transfer modelling yemabhatiri, mabhatiri e lithium-ion anoonekwa seane anisotropic thermal conductivity. Saka, zvakakosha zvikuru kudzidza nezvesimba renzvimbo dzakasiyana dzekupisa uye nzvimbo dzekupisa pakupisa uye kupisa kwemabhatiri e lithium-ion pakugadzira masisitimu ekuchengetedza kupisa anoshanda uye akavimbika emabhatiri e lithium-ion.
Sero rebhatiri re50 A·ah lithium iron phosphate rakashandiswa sechinotsvakurudzo, uye hunhu hwaro hwekuchinjana kupisa hwakaongororwa zvakadzama, uye pfungwa itsva yekugadzira thermal management yakakurudzirwa. Chimiro chesero chinoratidzwa muMufananidzo 1, uye maparamita chaiwo ehukuru anoratidzwa muTafura 1. Maumbirwo ebhatiri reLi-ion anowanzo sanganisira positive electrode, negative electrode, electrolyte, separator, positive electrode lead, negative electrode lead, center terminal, insulating material, safety valve, positive temperature coefficient (PTC)(PTC Inotonhorera Heater/PTC Air Heater) thermistor nebhokisi rebhatiri. Chinopatsanura chinoiswa pakati pezvidimbu zve positive ne negative pole, uye bhatiri rinoumbwa nekumonera kana kuti boka re pole rinoumbwa nekumonera. Nyoresa chimiro chemasero akawanda kuita sero rine saizi imwe chete, uye ita kurapa kwakaenzana pamatanho e thermophysical esero, sezvakaratidzwa muMufananidzo 2. Chinhu chebheteri chinofungidzirwa kuti iyuniti ye cuboid ine hunhu hwe anisotropic thermal conductivity, uye thermal conductivity (λz) yakatarisana negwara re stacking yakagadzirirwa kuva diki pane thermal conductivity (λ x, λy) yakaenzana negwara re stacking.
(1) Kugona kwekupisa kwechirongwa chekuchengetedza kupisa che lithium-ion battery kuchakanganiswa nematanho mana: kufambisa kupisa kwakatarisana nepamusoro pekupisa, daro renzira pakati penzvimbo inopisa nenzvimbo inopisa, saizi yenzvimbo inopisa yechirongwa chekuchengetedza kupisa, uye musiyano wekupisa pakati penzvimbo inopisa nenzvimbo yakapoteredza.
(2) Pakusarudza nzvimbo yekudzima kupisa yekugadzirwa kwemabhatiri e lithium-ion, nzira yekufambisa kupisa yedivi yechinhu chakasarudzwa chekutsvaga iri nani pane nzira yekufambisa kupisa yepasi, asi kune mabhatiri ane saizi dzakasiyana, zvakakosha kuverenga kugona kwekubvisa kupisa kwenzvimbo dzakasiyana dzekudzima kupisa kuitira kuziva nzvimbo yakanakisa yekutonhodza.
(3) Fomura iyi inoshandiswa kuverenga nekuongorora kugona kupisa, uye kuenzanisa kwenhamba kunoshandiswa kuona kuti mhedzisiro yacho inowirirana zvakakwana, zvichiratidza kuti nzira yekuverenga inoshanda uye inogona kushandiswa senzira yekutarisa pakugadzira manejimendi yekupisa yemasero madiki.BTMS)
