Kasi Mpikisano Ni vichi?

Coolant ni vinthu ivyo vikuchimbira mu batire linu la packs kuti vileke kuphika. Fundo yipusu comene kweni ŵanthu ŵanandi ŵakuciwona kuti ŵabudiska.

Mu EV na ESS mapulogalamu tikuyowoya za glycol - maji kusakaniza kuzingilizgika kwizira mu mbale zakuzizima panji nthowa zakuzizimitsa izo zikupangika na makina mu kapangidwe ka paketi. Maji ghakutora kutentha kwa maselo, ghakuchinyamura ku chiller panji radiator, ghakuponya moto, ghakuwelera ku vinyake. Loop wakulutilira kuchimbira kwa nyengo yitali apo paketi yikugwira ntchito.

Kujiŵika pa Fluid.

Luŵani chilichose icho mukumanya pa kuzizima kwa autotive. Prestone iyo yakubiriŵira kufuma ku AutoZone yizamuparanya batire. Vinthu ivyo vikukanizga dzimbiri mu antifreeze yakumanyikwa ni vyakupangika vya ionic - vikupanga magesi. Mukuchimbira ichi kwizira mu 400V pack, mukupempha viheni vya pasi.

Battery coont yikwenera kufiska vinthu viŵiri ivyo vikukhumbikwira kuti antifreeze wa nyengo zose waŵikepo mtima yayi:

Electrical resistivity above 100 kΩ·cm minimum. Most OEMs spec 150 kΩ·cm or higher. Tesla's spec calls for >200 kĩm pa kuzura kwatsopano.

Ion ivyo vili pasi pa 25 ppm. Ma specs ghanyake ghakuti 10 ppm. Ichi ndicho chifukwa mungagwiliskira ntchito waka maji ghakupangika na kusakanizga yayi -}glycol iyo yikwenera kuŵa ultra-Ŵanthu.

BASF Glysantin G40 na Arteco Havoline XLC ni viŵiri ivyo muzamuwona kanandi mu munda. Chevron nayo wakupanga batire-specification. Ivi vikuchitika pafupifupi $ 40-60 pa galoni na $ 12-15 pa OAT yakuzizima nyengo zose. Chakwenelera.

Sayika pa Ratio

50/50 Ethylene glycol ku maji gha deionized nkhwakuzomerezgeka. Ŵanyamata ŵanyake ŵakuchimbira 60/40 mu nyengo zakuzizima. Kuluta pachanya pa 60% glycol kukupweteka nadi -viscosity kukukwera, kutumizga kutentha kukukhira, pampu yikugwira ntchito mwamwamphu.

masamu gha nyengo yakuzizima:

50/50 kuwongolera pafupifupi -37 degree

60/40 yikumupani panji -52 degree

Glycol yakutowa yikuzizima pa -12℃(enya, kusazgapo maji ghakukhizga malo ghakuzizima, chemistry njambura kumanyikwa)

Kwa ŵanandi ŵa ku North America 50/50 ŵali makora. Usange mukuŵika mapaketi ku Minnesota panji Alberta, yowoyani na injiniya winu wa kutentha kuti mulute ku malo ghasambazi.

Mtengo Wakukwera

Apa ndipo nkhuwona chisokonezgo chomene. Ŵanthu ŵali na nthowa zakujumphamo mapampu panji kuziŵika pasi.

Kuŵerengera nkhwakusuzga yayi. Mukwenera kumanya vinthu vitatu:: usange paketi yikupanga moto, nyengo wuli iyo mungakwaniska kuzizipizga pa dera ili, ndiposo kutentha kwakuzizima kwanu kwakuzizima.

Pa 50/50 EG / maji kusakanizga, kutentha kwapadera kuli pafupifupi 3.3 kJ / kg·K. Kusuntha pafupifupi 1.07 kg / L.

Tiyelezgere kuti muli na 75 kWh pack ya 2C yakufumiska. Ndiyo 150 kW output. Chithunzi 5{{6}6% kutentha kwa mtundu pa mlingo uwo {- it 8 kW thermal katundu. Usange mukukhumba kusunga interil…{10}} ku-kunja delta pasi pa 4 delta :

8000 W ÷ (1.07 kg/L × 3300 J/kg·KK × 4 K) × 60=34 L / min

Iyi ni nambara yeneco kufuma ku pulojekiti yeneco. Pampu yeneco iyo ti spec yikaŵikika 40 L / min kuti yitipe chipinda cha mutu.

Mapaketi ghanandi gha EV gha ŵakwendeska galimoto ghakuchimbira 8-15 L / min pa katundu wakwenelera wakuyendeska. Kubuka pa nyengo ya kuchapa mwaluŵiro panji nkhongono zakukhozga.

Ivyo Vi Goes Vikuchita

Kuwona mitundu yichoko waka yakutondeka kwa vyaka vinandi.

Mtundu wakuzizima wakuzizima.Sinthani pachanya na antifreeze yakumanyikwa pa nyengo ya uteŵeti. Kukonkheska kukukwera. BMS yikuwona kuti pali suzgo la kujipatura, paketi yikujara. Usange muli na mwaŵi waka kuponya waka makhodi. Usange mulije mwaŵi kuti muŵe na arcing ya mukati.

Kufipiskika.Uwemi wa maji ngwakuzirwa. Malo ghanyake nkhagwiranga ntchito na maji gha pa mpopi kuti ghazure pakwamba chifukwa "chikujumpha mu ionizer nanga vili nthena." Kupaturapo kuti ŵakajumphiska deizer. Chloride ivyo vikaŵapo vikaŵa 180 ppm. Ŵakeneranga kusintha ndondomeko yose na kuŵika malo ghakuzizima - $ 40k pa $ 200k kuŵika.

wakunangika pakujumpha kwa nyengo.Glycol oxidizes. Mafomu gha glycolic, uyo pa nyengo iyo wakaŵa oxalic acid. pH madontho. Vinthu vyakukanizga dzimbiri vikugwiriskirika nchito. OEMs ŵakuti 4{6}} 5 chaka cha uteŵeti kweni nawona kuti kuzizima kukuchitika mu vyaka 2 mu malo ghapachanya. Mayeso pa chaka.

Mpweya mu dongosolo.Kufumiska ndopa za EV nkhwakutowa. Mathumba gha mphepo ghakupangiska malo ghakotcha. Selo ilo lili pasi pa bubble likuchitika 8-10℃kutentha chomene kuluska ŵazengezgani ŵake. Kucedwa kucekura, kuzgeŵa kwa nkhongono, pamanyuma pake kukukhumba.

Kuyezgeka Kuyezga

Mukukhumbikwira vipimiro vitatu:

pH {- yakuzizima yikuchimbira 7.8 ku 8.5 mwakuyana na kupanga. Pansi pa 7.0 kukung’anamura kuti phukusi lakukanizga likuchepa. Sinthani.

Kukanizga {{{{llit}} mita yakukhozgeka kulipo kweni ŵakudura. Tumirani sampulo ku labotale usange mulije. Chilichose icho chili pasi pa 50 kΩ·cm chikupokera pafupi.

Glycol concentration {{llit}} recractometer yikugwira ntchito. $ 30 chida, chikutora masekondi 10. Mukuwoneseska kuti ŵadumurenge kufuma ku condensation panji munthu munyake uyo wakusazgapo maji ghakwenelera.

Mapulotini ghanyake ghakuchita mapulogiramu ghakuwonera mafuta, ghakutuma masampulo ku Polaris Labs panji Blackstone pa myezi 6 yiliyose. Overkill kwa mapulogalamu ghanandi kukupangiska kuti viŵe vyakupulikikwa kuti viŵikidwe mu malo ghakuru.

Kuŵikika kwakulongozgeka na Kuzizimitsa Kwambura Kurongosora

Chilichose icho chili pachanya apa chikughanaghana kuti chizizima mwachindunji- fluid chikuchimbira kwizira mu nthowa, chikukhwaska yayi maselo. Icho ndicho 95% ya ivyo vili kuwaro uko.

Kubizgika mwaluŵiro kukupambana. Maselo ŵakukhala mu kugeza maji gha dielectric. Palije mbale zakuzizima, palije chinthu chakutentha, maji ghakukhwaskana na chiŵiya cha maji mwaluŵiro. Kutentha kwakutenthemeska nkhwawemi. Kusuzga kuli pasi mu nthowa zinyake, nkhwapachanya mu vinyake.

Maji ghakupambanaso. 3M Novec na Solvay Galden ni mazina ghakuru. Ivi ni vyakupangika vya fluorinated, vyakupangiska kuti viŵe vyakucepa comene, vyakusazgapo vya kemiko. Kweniso nchakudura chomene {{3} $ 300-400 pa lita pa vinyake vyakupangika.

Kuŵikika mwaluŵiro kukuwoneka mu kusunga gridi na vinyake vyakukwera -} ntchito ya galimoto. Kufikapo yayi kweni nchito ya kutentha njakusuzga kugazgana nayo.

Kulongosora mwaluŵiro ivyo mungapenja para mukupenja batire lakuzizima:

Penjani MSDS na data ya data ya data kufuma ku wakupeleka. Usange ŵangakwaniska yayi kupereka data yakukanizga, sangani munthu munyake uyo wakupeleka vinthu.
