Yintoni Ukupholisa?

Ukupholisa zizinto ezihamba ngebhetri yakho egcina iiseli ekuziphekeni ngokwazo. Ingqikelelo elula kakhulu kodwa abantu abaninzi abayiqondi kakuhle.

Kwi-EV kunye ne-ESS applications sithetha nge-glycol-umxube wamanzi ajikeleza kwiipleyiti ezibandayo okanye amajelo okupholisa afakwe kwisakhiwo sepakethi. Ulwelo luthatha ubushushu kwiiseli, bubuthwale buyise kwi-chiller okanye kwiradiyetha, bukhuphe ubushushu, bubuye buphinde bubuye. I-Loop iqhubeka isebenza nje ukuba ipakethe isebenza.

Ulwelo ngokwalo

Ulibale nantoni na oyaziyo malunga nokupholisa iimoto. Loo Prestone eluhlaza evela kwi-AutoZone iya kutshabalalisa ipakethi yebhetri. I-corrosion inhibitors kwi-conventional antifreeze ziikhompawundi ze-ionic-ziqhuba umbane. Uqhuba oko ngepakethi ye-400V, ucela iimpazamo zomhlaba.

Ukupholisa ibhetri kufuneka kuhlangabezene neemfuno ezimbini apho isithinteli-mkhenkce esiqhelekileyo esingakhathaliyo:

Electrical resistivity above 100 kΩ·cm minimum. Most OEMs spec 150 kΩ·cm or higher. Tesla's spec calls for >200 kΩ·cm ekugcwaliseni okutsha.

Umxholo we-ion ngaphantsi kwe-25 ppm. Ezinye iinkcukacha zithi 10 ppm. Yiyo loo nto ungenako ukusebenzisa amanzi adibeneyo kwaye udibanise awakho{4}}iglycol ngokwayo kufuneka ibe nyulu kakhulu-.

I-BASF Glysantin G40 kunye ne-Arteco Havoline XLC zezona zimbini oza kuzibona rhoqo ebaleni. I-Chevron yenza kwakhona ibhetri{2}}ukwakheka okukodwa. Ezi zibaleka malunga ne-40-60 yeedola ngegaloni nganye ngokuchasene ne-12-15 yeedola zokupholisa rhoqo kwe-OAT. Ikufanele oko.

Mix Ratio

I-50/50 i-ethylene glycol kumanzi adibeneyo asemgangathweni. Abanye abafana baqhuba i-60/40 kwiindawo ezibandayo. Ukuya ngaphezulu kwe 60% glycol eneneni kuyakwenzakalisa{7}}i-viscosity iyenyuka, ukuhanjiswa kobushushu kuyehla, impompo isebenza nzima.

Indawo yokukhenkceza izibalo:

50/50 umxube umkhenkce malunga -37 degree

60/40 ikwenza ukuba mhlawumbi -52 degree

I-glycol ecocekileyo ikhenkceka kwi--12℃(ewe, ukongeza amanzi kunciphisa indawo yokukhenkceza, i-chemistry iyamangalisa)

Kuninzi loMntla Merika i-50/50 ilungile. Ukuba uthumela iipakethi eMinnesota okanye eAlberta, thetha nenjineli yakho yobushushu malunga nokutyeba.

Umgangatho wohambo

Kulapho ndibona khona ukubhideka kakhulu. Abantu nangayiphi na indlela bagqithise iimpompo okanye bangaphantsi kwazo.

Ubalo aluntsonkothanga. Kufuneka wazi izinto ezintathu: bungakanani ubushushu obuveliswa yipakethi, loluphi ubushushu obunyukayo onokubunyamezela kwisekethe yonke, kunye nobushushu obuthile besipholisi sakho.

Kumxube we-50/50 EG / wamanzi, ukushisa okuthe ngqo malunga ne-3.3 kJ / kg · K. Uxinaniso malunga ne-1.07 kg/L.

Yithi unepakethi engama-75 kWh ekhupha i-2C. Leyo yi-150 kW imveliso. Umfanekiso 5-6% wokuvelisa ubushushu ngolo hlobo{9}}yibize nge-8 kW yomthwalo oshushu. Ukuba ufuna ukugcina ukungena{10}}ukukhupha idelta ngaphantsi kwe 4℃:

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

Elo linani lokwenyani elisuka kwiprojekthi yokwenyani. Eyona mpompo sithe sayibalula inikwe i40 L/min ukusinika igumbi lentloko.

Uninzi lweepakethi ze-EV zabagibeli ziqhuba i-8-15 L / min kwimithwalo eqhelekileyo yokuqhuba. Amaqhuqhuva ngexesha lokutshaja ngokukhawuleza okanye ukugcinwa kwamandla aphezulu.

Yintoni Engahambi kakuhle

Ndibone iindlela ezimbalwa zokusilela kwiminyaka.

Uhlobo lokupholisa olungalunganga.Thenga izinto eziphezulu kunye ne-antifreeze eqhelekileyo ngexesha lenkonzo. I-conductivity spikes. I-BMS ibona impazamo yokuzahlula, ipakethe iyavala. Ukuba unethamsanqa iphosa nje iikhowudi. Ukuba awunathamsanqa ufumana i-arcing yangaphakathi.

Usulelo.Umgangatho wamanzi ubalulekile. Enye indawo endiyisebenzeleyo isebenzise amanzi okupompoza ukugcwaliswa kokuqala kuba "ihamba nge-deionizer kunjalo." Ngaphandle kokuba badlule kwi-deionizer. Umxholo weChloride wawuyi-180 ppm. Kwafuneka ugungxule yonke inkqubo kwaye endaweni iipleyiti ezibandayo -$40k umsebenzi kwi $200k ufakelo.

Ukuthotywa kwexesha.Glycol oxidizes. Yenza i-glycolic acid, emva koko i-oxalic acid. i-pH iyehla. Ii-Corrosion inhibitors ziyasetyenziswa. Ii-OEMs zithi 4-isithuba senkonzo seminyaka emi-5 kodwa ndibone ukupholisa kuhamba kakubi kwiminyaka emi-2 kwindawo yobushushu obuphezulu. Vavanya qho ngonyaka.

Umoya kwinkqubo.Ukupholisa iilophu ze-EV zokupholisa ziphelile. Iipokotho zomoya zibangela iindawo ezishushu. Iseli ngqo phantsi kweqamza ibaleka 8-10℃shushu kunabamelwane bayo. Ukuguga okukhawulezileyo, amandla aphela, ekugqibeleni ibango lewaranti.

Uvavanyo lweMeko yokupholisa

Udinga imilinganiselo emithathu:

pH{{0}isipholisi esitsha sibaleka 7.8 ukuya ku-8.5 ngokuxhomekeke kumxube. Ngaphantsi kwe-7.0 kuthetha ukuba iphakheji ye-inhibitor iphelile. Yitshintshe.

Ukuxhathisa{0}}iimitha eziphathwayo zikhona kodwa ziyabiza. Thumela isampuli elebhu ukuba awunayo. Nantoni na engaphantsi kwe 50 kΩ·cm ifumana i marginal.

IGlycol concentration{0}}isebenza irefractometer. $30 isixhobo, kuthatha 10 imizuzwana. Ujonge ukuhlanjululwa ukusuka kwi-condensation okanye umntu wongeza amanzi athe ngqo.

Ezinye iiflethi zenza iinkqubo zesitayile sokuhlalutya ioyile, zithumela iisampulu kwiPolaris Labs okanye kwiBlackstone rhoqo ngeenyanga ezi-6. I-Overkill kwizicelo ezininzi kodwa iyavakala kufakelo olukhulu.

Ukuntywiliselwa okuthe ngqo vs ukuPholisa okungathanga ngqo

Yonke into engentla ithatha ukupholisa okungathanga ngqo{0}}ulwelo oluhamba kwizitishi, alukhe luchukumise iiseli. Ngama-95% ezinto ezikhoyo.

Ukuntywiliselwa ngokuthe ngqo kwahlukile. Iiseli zihlala kwibhafu ye-dielectric fluid. Akukho pleyiti zibandayo, akukho sixhobo se-thermal interface, unxibelelwano lwe-fluid ngokuthe ngqo. Ukutshintshwa kobushushu kungcono. Ukuntsokotha kusezantsi ngeendlela ezithile, kuphezulu kwezinye.

Ulwelo lwahlukile kwakhona{0}}M Novec kunye neSolvay Galden ngamagama amakhulu. Ezi zikhompawundi ezine-fluorinated, conductivity ephantsi kakhulu, inert yekhemikhali. Kananjalo zibiza kakhulu-$300-400 ilitha nganye kwezinye imixube.

Untywiliselo oluthe ngqo lubonakala kugcino lwegridi kunye nolunye{0}}usetyenziso oluphezulu lwezithuthi. Ayikabikho ephambili okwangoku kodwa ukusebenza kwe-thermal kunzima ukuphikisana nayo.

Iphepha Elikhethekileyo

Ireferensi ekhawulezayo yokuba ungajonga ntoni xa ukhangela into yokupholisa ibhetri:

Fumana i-MSDS kunye nephepha ledatha yobugcisa kumthengisi wakho. Ukuba abanako ukubonelela ngedatha yokuxhathisa, fumana umboneleli owahlukileyo.
