Thermal Management Solutions yeBattery Systems

Hapana mubvunzo kuti tembiricha chinhu chine chekuita kwakakosha pakuita, hupenyu uye kuchengetedzeka kwemabhatiri emagetsi.Kazhinji, isu tinotarisira kuti bhatiri system ishande mukati me15 ~ 35 ℃, kuitira kuti tiwane yakanakisa simba rekubuda nekuisa, iyo yakanyanya kuwanikwa simba, uye hupenyu hurefu hwekutenderera (kunyangwe tembiricha yakaderera inogona kuwedzera hupenyu hwekarenda. yebhatiri , asi hazvina musoro kuti udzidzire pasi-tembiricha kuchengetedza mumaapplication, uye mabhatiri akafanana chaizvo nevanhu mune iyi nyaya).

Parizvino, iyo yekupisa manejimendi yesimba bhatiri system inogona kunyanya kukamurwa kuita zvikamu zvina, kutonhora kwechisikigo, kutonhora kwemhepo, kutonhora kwemvura, uye kutonhora kwakananga.Pakati pazvo, kutonhora kwechisikigo inzira yekupisa yekupisa, nepo kutonhora kwemhepo, kutonhora kwemvura, uye yakananga ikozvino inoshanda.Musiyano mukuru pakati pezvitatu izvi mutsauko wepakati wekutsinhanisa kupisa.

· Kutonhora kwepanyama
Kutonhodza mahara hakuna mamwe madivayiri ekuchinjana kupisa.Semuenzaniso, BYD yakagamuchira kutonhora kwechisikigo muQin, Tang, Song, E6, Tengshi uye mamwe mamodheru anoshandisa LFP masero.Zvinonzwisiswa kuti iyo yekutevera BYD ichachinja kune kutonhora kwemvura kune modhi uchishandisa ternary mabhatiri.

· Mhepo Kutonhodza (PTC Air Heater)
Kutonhodza mhepo kunoshandisa mweya senzira yekutamisa kupisa.Kune marudzi maviri akajairika.Yekutanga inonzi passive air cooling, iyo inoshandisa zvakananga mweya wekunze wekuchinja kupisa.Rudzi rwechipiri runoshanda kutonhora kwemhepo, iyo inogona kufanopisa kana kutonhorera kunze kwemhepo isati yapinda mubhatiri system.Mumazuva ekutanga, akawanda maJapan neKorea emagetsi emagetsi akashandisa mhepo-yakatonhorera mhinduro.

· Kutonhora kwemvura
Kutonhodza kwemvura kunoshandisa antifreeze (senge ethylene glycol) semhepo yekutamisa kupisa.Kune anowanzo akawanda akasiyana kupisa kupisa maseketi mune mhinduro.Semuyenzaniso, VOLT ine reyedhiya wedunhu, air conditioning circuit (PTC Air Conditioning), uye PTC dunhu (PTC Inotonhorera Heater)Iyo bhatiri manejimendi system inopindura uye inogadzirisa uye inochinja zvinoenderana neiyo thermal management strategy.Iyo TESLA Model S ine dunhu munhevedzano ine mota kutonhora.Kana bhatiri richida kudziirwa pakadzika tembiricha, iyo mota inotonhorera yedunhu yakabatana munhevedzano nebhatiri kutonhora redunhu, uye mota inogona kupisa bhatiri.Kana bhatiri remagetsi riri patembiricha yakakwira, dunhu rekutonhodza mota uye bhatiri rekutonhodza redunhu rinogadziriswa rakafanana, uye maviri ekutonhodza masisitimu anobvisa kupisa akazvimirira.

· Kutonhora kwakananga
Kutonhora kwakananga kunoshandisa refrigerant (phase-changing material) senzvimbo yekutsinhanisa kupisa.Iyo firiji inogona kutora huwandu hukuru hwekupisa panguva yegasi-mvura yechikamu chekuchinja maitiro.Kuenzaniswa nefiriji, kupisa kwekushisa kunogona kuwedzerwa nekanopfuura katatu, uye bhatiri rinogona kuchinjwa nokukurumidza.Kupisa mukati megadziriro kunotakurwa.Iyo yakananga kutonhora chirongwa yakashandiswa muBMW i3.

 

Pamusoro pekushanda kwekutonhora, iyo thermal management scheme yebhatiri system inoda kufunga nezve kuenderana kwekushisa kwemabhatiri ese.PACK ine mazana emasero, uye tembiricha sensor haigone kuona yesero.Semuenzaniso, kune 444 mabhatiri mune module yeTesla Model S, asi 2 chete tembiricha yekuona nzvimbo dzakarongwa.Naizvozvo, zvinodikanwa kuita kuti bhatiri rive rinoenderana sezvinobvira kuburikidza nekupisa manejimendi dhizaini.Uye yakanaka tembiricha kusarongeka ndiyo inodiwa yekuenderana kuita ma paramita senge simba rebhatiri, hupenyu, uye SOC.
