Waa maxay xaaladda dacwadda (SOC) maxayse muhiim u tahay?

Xaaladda lacag-qaadista (SOC) waxa ay tilmaamaysaa cadadka tamarta hadda ku kaydsan baytariga, oo lagu muujiyay boqolkiiba wadarta awoodda batteriga. Ogaanshaha SOC waa muhiim sababtoo ah waxay kaa caawinaysaa inaad fahanto inta tamar ee la heli karo iyo ilaa inta qalabkaaga ama nidaamkaagu sii shaqayn karo ka hor inta aanad u baahnayn in dib lagu dalacsiiyo. Tusaale ahaan, haddii talefankaaga casriga ahi uu leeyahay batari leh 50% SOC, waxay la macno tahay in uu isticmaalay kala badh tamartiisa oo laga yaabo in uu u baahdo in degdeg lagu dallaco.

Sidoo kale, haddii aad isticmaalayso habka cadceedda si aad u koronto gurigaaga, la socodka SOC ee baytariyadaadu waxay kaa caawin kartaa inaad hubiso inaad haysato tamar kugu filan si aad u daboosho baahiyahaaga xilliyada iftiinka qorraxdu hooseeyo ama baahida sare. Markaad isha ku hayso SOC oo aad qaado tillaabooyin ku habboon si aad dib ugu buuxiso ama u kaydsato tamarta hadba sida loogu baahdo, waxaad sare u qaadi kartaa waxqabadka iyo cimriga baytariyadaada iyo qalabkaaga.

Xaaladda Kharashka Bateriga - Sideed u go'aaminaysaa heerka kharashka? Maxaa loola jeedaa xaaladda dacwadda?

Marka lagu jiro baytariga aashitada rasaasta, waa maxay macnaha Xaaladda Kharashka?

Xaaladda Kharashka (SoC) waa erey loo isticmaalo in lagu qeexo heerka dallacaadda hadda ee batteriga marka loo eego wadarta awoodda. Waxaa lagu muujiyey boqolkiiba, iyadoo 0% ay ka dhigan tahay batari si buuxda u baxay iyo 100% oo ka dhigan baytari si buuxda u dallacay. SoC waxa ay bixisa tilmaanta inta tamarta laga heli karo batteriga waqti go’an waxayna ka caawisaa isticmaalayaasha inay maareeyaan isticmaalkooda tamarta iyo dhaqamada dallacaadda.

Maxaad u baahan tahay inaad ka ogaato caafimaadka batteriga si aad u ilaaliso SOC sare?

Si aad u ilaaliso kharash sare (SOC) batterigaaga, waa muhiim inaad fahanto fikradda caafimaadka batteriga. Caafimaadka baytarigu waxa uu tilmaamayaa xaaladda guud iyo waxqabadka batterigaaga, waxaana saamayn kara arrimo ay ka mid yihiin heerkulka, qaababka isticmaalka, iyo caadooyinka dallacaadda.

Si aad u ilaaliso batteri caafimaad qaba oo aad sare ugu qaaddo SOC, waa inaad:

  • Iska ilaali inaad u soo bandhigto qalabkaaga heerkul aad u daran, sababtoo ah tani waxay dhaawici kartaa batteriga waxayna yaraynaysaa awoodiisa guud.
  • Iska ilaali inaad si joogto ah u daadiso batterigaaga, sababtoo ah tani waxay sidoo kale hoos u dhigi kartaa awoodiisa waqti ka dib.
  • Isticmaal xajiyeyaasha tayada sare leh ee loogu talagalay qalabkaaga, iskana ilaali isticmaalka dabaysha jaban ama been abuurka ah ee waxyeelayn kara baytarigaaga.
  • Si joogto ah u dallaci batterigaaga si uu kor ugu sii qaado, intii aad sugi lahayd ilaa uu ku dhow yahay faaruq ka hor intaadan dallacin.
  • Tixgeli isticmaalka sifooyinka tamarta-badbaadinta ee qalabkaaga si aad u kordhiso nolosha batteriga oo aad u yareyso qulqulka aan loo baahnayn.

Markaad raacdo talooyinkan oo aad si fiican u daryeesho batterigaaga, waxaad kaa caawin kartaa inaad hubiso inuu caafimaad qabo oo uu sii hayo SOC sare waqti ka dib.

Sidee loo cabbiraa heerka dallaca batteriga aashitada rasaasta?

Isticmaale ahaan, waxaad go’aamin kartaa Xaaladda Kharashka (SoC) ee baytariga-ashitada rasaasta adoo isticmaalaya dhowr cabbir:

  • Habka Voltage Battery: Mid ka mid ah siyaabaha ugu fudud ee lagu qiyaasi karo SoC waa iyada oo la cabbirayo tamarta wareegga furan ee batteriga (OCV) iyadoo la adeegsanayo multimeter marka uu batteriga ku jiro nasasho (sida, aan la dallacin ama laga saarin). Cabbirka tamarta batteriga ayaa markaa la barbar dhigi kara jaantuska tixraaca danab-ilaa-SoC ee ay bixiso soo-saaraha ama laga helo khadka. Maskaxda ku hay in habkani yahay qiyaas kaliya oo laga yaabo in aanu si buuxda u sax ahayn arrimo ay ka mid yihiin heerkulka batteriga iyo da’da.
  • Cabbirka cuf-jiidadka gaarka ah: Batariyada acid-ashitada rasaasta daadku , waxaad ku cabbiri kartaa cuf-jiidadka gaarka ah ee korantada adiga oo isticmaalaya hydrometer. Cuf-jiidadka gaarka ah wuxuu la xiriiraa SoC , marka la barbardhigo qiimaha la cabbiray iyo jaantus tixraaceedka cuf-jiidad-SoC-ga gaarka ah waxay bixin doontaa qiyaasta SoC. Habkani wuu ka saxsan yahay cabbiraadda korantada laakiin wuxuu u baahan yahay maarayn habboon iyo taxaddarrada badbaadada marka la shaqaynayo batteriga elektrolytka.

Shaxda tixraaca ee Voltage-to-SoC ee baytariga aashitada rasaasta

Maskaxda ku hay in jaantusyada tixraaca danab-ilaa-SoC ay kala duwanaan karaan iyadoo ku xiran nooca batteriga, saaraha, iyo heerkulka gaarka ah. Kuwa soo socdaa waa jaantuska tixraaca guud ee 12V baytari-ashitada rasaasta ah ee heerkulka qolka (25°C ama 77°F):

Xaaladda batteriga lithium-ion? qiyaasta iyadoo la isticmaalayo habka tirinta coulomb

Tirinta Coulomb: Habkani waxa uu ku lug leeyahay la socodka hadda socda ama ka baxaya batteriga si loo xisaabiyo kharashka hadhay. Qalabka la socodka baytariyada gaarka ah ama nidaamka maaraynta baytariga (BMS) ayaa loo isticmaali karaa ujeedadan. Iyadoo uu ka saxsan yahay danab iyo cabbirada cufisjiidka gaarka ah, habkani wuxuu u baahan yahay qalab dheeraad ah wuxuuna u nuglaan karaa khaladaadka sababo ay ka mid yihiin hufnaanta batteriga iyo is-bixidda.

Jaantuska heerka batteriga lithium (SoC).

Shaxda heerka dallaca ee baytariga lithium (SoC) waa matalaad guud ee xidhiidhka ka dhexeeya heerka dallaca ee baytariga lithium-ion iyo danabtiisa. Shaxdan waxa loo isticmaali karaa in lagu qiyaaso inta hadhay ee batteriga iyadoo lagu salaynayo danabkiisa hadda. Fadlan xasuusnoow in tani ay tahay qiyaas kaliya, maadaama qalooca korantada dhabta ah uu kala duwanaan karo iyadoo ku xiran tahay kimisteriga batteriga gaarka ah, heerkulka, iyo heerka dheecaanka.

Halkan waxaa ah jaantuska heerka batteriga lithium ee la fududeeyay:

Maskaxda ku hay in heerarka danabka iyo qiyamka SoC ee u dhigma ay wax yar ku kala duwanaan karaan kimistarada lithium-ion ee kala duwan, sida LiCoO2 (LCO), LiMn2O4 (LMO), LiFePO4 (LFP), ama LiNiMnCoO2 (NMC). Sidoo kale, xasuusnoow in qiyaasta SoC-ku-saleysan korontadu leedahay xaddidaadyo iyo nidaamyada maareynta batteriga (BMS) inta badan waxay isticmaalaan algorithms-ka adag ee tixgeliya arrimo dheeri ah si ay u bixiyaan qiyaas SoC oo sax ah.

Xaaladda Kharashka - SoC ee nidaamka maaraynta baytariga

Kormeerayaasha baytariyada casriga ah: Qaar ka mid ah nidaamyada maaraynta baytariyada horumarsan ama BMS waxay ku siin karaan macluumaadka cabbiraadaha batteriga waqtiga dhabta ah iyadoo la adeegsanayo isku-darka algorithm ee korantada, hadda, heerkulka, iyo cabbirada kale. Aaladahani waxay bixiyaan habka ugu saxsan uguna haboon ee lagula soconayo xaalada batteriga SoC laakiin waxaa laga yaabaa inay ku yimaadaan qiimo sare.

Faa'iidooyinka cabbiraadda xaaladda kharashka

Markaad la socoto SoC, waxaad si fiican u maareyn kartaa isticmaalka batterigaaga iyo dhaqamada dallacaadda, iyadoo la hubinayo in batterigu aanu si xad dhaaf ah u dayn ama u dalacin, taasoo ka caawin karta inuu cimrigiisa dheereeyo oo uu joogteeyo waxqabadka ugu fican.
