Lithium-ion bhatiri kupisa kupisa maitiro uye kupisa manejimendi dhizaini

Nekuwedzera kwekutengesa uye varidzi vemotokari dzesimba idzva, tsaona dzemoto dzemotokari dzemagetsi matsva dzinoitikawo nguva nenguva.Dhizaini yeiyo thermal management system idambudziko remabhodhoro rinomisa kugadzirwa kwemotokari nyowani dzesimba.Kugadzira yakagadzikana uye inoshanda yekupisa manejimendi system yakakosha zvikuru pakuvandudza kuchengetedzeka kwemotokari nyowani dzesimba.

Li-ion bhatiri thermal modelling ndiyo hwaro hweLi-ion bhatiri thermal management.Pakati pavo, kupisa kwekushisa hunhu hwekuenzanisira uye kupisa chizvarwa chechimiro chekuenzanisa zvinhu zviviri zvakakosha zve lithium-ion bhatiri thermal modeling.Muzvidzidzo zviripo pakuenzanisa maitiro ekupisa kupisa kwemabhatiri, lithium-ion mabhatiri anoonekwa seane anisotropic thermal conductivity.Nokudaro, zvakakosha zvikuru kudzidza kushandiswa kwezvinzvimbo zvakasiyana-siyana zvekupisa kupisa uye kupisa kwekushisa pamusoro pekupisa kupisa uye kupisa kwekushisa kwemabhatiri e-lithium-ion nokuda kwekugadzirwa kwemaitiro anoshanda uye anovimbika ekugadzirisa kupisa kwemabhatiri e-lithium-ion.

Iyo 50 A·h lithium iron phosphate bhatiri sero yakashandiswa sechinhu chekutsvagisa, uye maitiro ayo ekupisa kupisa akaongororwa zvakadzama, uye nyowani yekupisa manejimendi dhizaini zano.Chimiro chesero chinoratidzwa muMufananidzo 1, uye zviyero zvakakura zvakaratidzwa muTebhu 1. Li-ion bhatiri chimiro chinowanzobatanidza electrode yakanaka, electrode yakaipa, electrolyte, separator, positive electrode lead, negative electrode lead, center terminal, insulating zvinhu, vharafu yekuchengetedza, yakanaka tembiricha coefficient (PTC) (PTC Inotonhorera Heater/PTC Air Heater) thermistor uye bhatiri kesi.A separator akaiswa sandwich pakati pezvakanaka uye zvisina kunaka zvidimbu zvepango, uye bhatiri musimboti unoumbwa nemhepo kana boka remapole rinoumbwa nelamination.Rerutsa iyo yakawanda-layer sero chimiro kuita sero zvinhu zvine saizi yakafanana, uye ita kurapa kwakaenzana pane thermophysical parameters yesero, sezvakaratidzwa mumufananidzo 2. Iyo bhatiri cell zvinhu inofungidzirwa kuve cuboid unit ine anisotropic thermal conductivity maitiro. , uye thermal conductivity ( λz ) perpendicular kune stacking direction inogadzirirwa kuva diki pane thermal conductivity ( λ x , λy ) inopindirana kune stacking direction.

(1) Kupisa kwekupisa simba kweiyo lithium-ion bhatiri yekudziya manejimendi system ichakanganiswa nezvikamu zvina: thermal conductivity perpendicular to the heat dissipation surface, nzira yekufamba pakati pepakati penzvimbo yekupisa uye kupisa kwekushisa, ukuru hwenzvimbo yekupisa yekupisa kweiyo thermal management scheme, uye musiyano wekushisa pakati penzvimbo yekupisa yekupisa uye nharaunda yakapoteredza.

(2) Paunenge uchisarudza nzvimbo yekupisa yekupisa yekupisa dhizaini yemabhatiri e-lithium-ion, iyo yekupisa kupisa hurongwa hwechinhu chakasarudzwa chekutsvagisa chiri nani pane yepasi pasi pekushisa kupisa hurongwa, asi kumabhatiri emativi akasiyana saizi, zvinodikanwa. kuverengera kupisa kwekupisa simba kwenzvimbo dzakasiyana dzekupisa kupisa kuitira Kuona nzvimbo yakanaka yekutonhora.

(3) Chimiro chinoshandiswa kuverenga uye kuongorora simba rekupisa kupisa, uye kuenzanisa kwenhamba kunoshandiswa kuona kuti mhedzisiro yacho inopindirana zvachose, zvichiratidza kuti nzira yekuverenga inoshanda uye inogona kushandiswa sereferensi pakugadzira iyo thermal management. dzema square cells.
