iseli Single: 3.20V igama / 3.65V isilingi intlawulo / 2.50V umgangatho absolute.
Kukho umgibe we-48V ofanele ukwazi ngaphambi kokuba ukuthengwa kuvalwe. Ezinye iitshaja zeasidi kunye nezilawuli ze-asidi ziyifektri{3}}zilungelelaniswe iipakethi ze-15S, ezihlawulisa ukuya kwi-54.75V epheleleyo kunesilingi eqhelekileyo ye-16S ye-58.4V. Faka ipakethe ye-16S kule nkqubo kwaye ayize ifikelele kwintlawulo epheleleyo. Uphawu lukhangeleka njengesiphene somthamo. Siye sabona izibonelelo zichitha iiveki zileqa ingxaki yeseli eneneni ibiyimpazamo yokulinganisa. Uluhlu logunyaziso lwePolinovel luqhuba isilawuli{13}}itshaja{14}}ipakethe uqinisekiso lokuhambelana kwamandla ombane kufakelo ngalunye ngesi sizathu kanye - luhlobo lwento oluvela emva kwePO, hayi ngaphambili.
Kutheni ukufundwa kweVoltage ngexesha leShift ephilayo ngokuyinyani kuyintsomi
Igophe lokukhupha le-LFP liphantse lacaba phakathi kwe-20% kunye ne-80% ye-SOC. Kwinkqubo ye-48V, lonke uluhlu olusebenzayo lwemveliso yeshifti - inxalenye ebaluleke kakhulu ekusebenzeni - idlula malunga ne-52V ukuya ku-54V. Iivolthi ezimbini kwi-60% yomthamo okhoyo. Amandla ombane{11}esekwe kwi-SOC algorithm esebenza kwela bhanti ayimeta nto; idibanisa ngengxolo, kwaye ikhemistri ayiniki nto inokubambelela kuyo. (diysolarforum.com)
Ukufumana i-voltage yokuphumla ecocekileyo enemephu ngokuchanekileyo kwi-SOC kufuna ukuba ipakethe ihlale ingasebenzi imizuzu engama-30 ukuya kwiiyure ezi-4 ngaphandle komthwalo kwaye akukho ntlawulo yangoku. Kwinkqubo embaxa -yeshift ngeithuba lokubizayakhelwe kwiishedyuli zekhefu, loo festile ayikho. I-BMS ifunda umdibaniso wayo nayiphi na i-voltage sag isiganeko somthwalo wokugqibela esishiywe ngasemva, intsalela yentlawulo yomphezulu ukusuka kowona phezulu{1}}phezulu, kunye neziphumo zokuchasana zangaphakathi ezikhukuliseka zibheka phezulu njengoko iiseli zikhula. Beka ezo zinto kunye kunye nesiboniso se-SOC sithwala ±15–20% yempazamo ecwangcisiweyo xa amandla ombane ebala. Siye sabona imiboniso ifundeka i-45% kwiipakethi ebezihleli kwi-28%. Ibonwe 60% ekunene phambi kokuba-kucuthwe amandla ombane asezantsi.
I-BMS yoshishino yePolinovel iqhuba ukuchaneka shunt{{0} kusekweukubala coulombnjengendlela yokuqala yeSOC. I-shunt ilinganisa i-ampere{1}}yesibini sogqitho kunye ne-algorithm igcina amandla asebenzayo alungiselelwa ubushushu kunye nokuguga. Ukuchaneka kommandla kuhlala ku-±3–5%, okuhambelana noko kuboniswa idatha yethu yokugunyazisa kuzo zonke iinkqubo ezisasaziweyo. I-voltage isalogiwe - isetyenziselwa iseli{7}}inqanaba lokuchongwa kobuphene kunye nokuchongwa kokungalingani. Ayithenjwa nje kuqikelelo lukarhulumente, kuba i-physics ye-LFP chemistry ayixhasi ngexesha lokusebenza okusebenzayo.
Ityala le-80V lenza ukuba i-arithmetic icace. Amashumi amabini -eselintlanu kuthotho. I-0.1V ye-conservative 0.1V nganye{5}}ngomlinganiselo wokungaqiniseki weseli iqokelelana ukuya kwi-2.5V kwinqanaba lepakethi. Kwanele ukuyichaza kakubi iSOC nge15–20 yepesenti yamanqaku ngokuxhomekeke kwindawo yegophe. Ukusebenza: ilori ebonisa i-40% kwisiboniso esivala phakathi{12}}nelifti kuba intlawulo yokwenyani iku-22%.
Ukugcinwa Okubandayo: Iingxaki ezimbini, kwaye abathengisi bakuxelela kuphela malunga nenye
Uninzi lweengxoxo zentengiso malungaebandayo-chain LFPYazisa ingxaki ebonakalayo: ngaphantsi kwe-0 degree, ukuxhathisa kweseli yangaphakathi spikes ngokwaneleyo ukuba amandla ombane ehle phantsi kweziganeko zokuphakamisa okunzima zibangela ukhuseleko olusezantsi{1}}loxa intlawulo enentsingiselo ihleli kwipakethi.
Abasebenzisi bacinga ukuba ibhetri ayisebenzi. Lifuthe lobushushu, liya lisiba mbi ngoFebruwari, kwaye liyacaphukisa. Iyalawuleka, kwaye ibhalwe kwizinto ezininzi zomthengisi ukuba uyabuza.
Ingxaki yesibini yeyokuba yintoni engayi kuvolontiya, kwaye imbi ngakumbi.
Tshaja iseli ye-LFP ngezantsi komkhenkce kunye nee-ion ze-lithium ekufuneka zidibanise kwi-graphite anode endaweni yepleyiti kumphezulu njenge-metallic lithium. Le lithium icwecwe ayiphinda idityaniswe ekukhutshweni. Iqokelela, ijikeleze emva komjikelezo, inciphisa ngokusisigxina umthamo osebenzayo. Inxalenye eyenza ukuba ibe yityhefu kurhwebo: kwigophe elicimekileyo, ayicaciswanga kwikhalenda yesiqhelo. I-Hit cycle 1,800 kunye ne-70% umthamo kwipakethi eqinisekisiweyo yokugcinwa kwe-80% ngokusebenzisa umjikelo we-3,500, kwaye akukho qela linedatha eyahlula ngokucacileyo "ihlawuliswe kwi-5℃amaxesha angamashumi amane ngoJanuwari" ukusuka "ukuthotywa kwesiqhelo." Ezo ngxoxo zewaranti azisombululi ngokucocekileyo, kwaye umsebenzisi uthatha impembelelo yokusebenza ngelixa ingxabano iqhuba.
Ukubanda kwePolinovel-itsheyini le-BMS livala ukuqaliswa kwentlawulo kwi-hardware sesekethe de iiseli zicace 5℃. Uqwalaselo olungalunganga lwe-firmware okanye uhlaziyo alunako ukulubhala ngaphezulu - utshixo luhlala ngaphantsi kwesoftware. Isiphaluka sokufudumeza sisebenza kumandla okufaka itshaja, akukho nxaxheba yabaqhubi efunekayo. Kwizibonelelo ezisebenza ngaphantsi kwe-10℃ambient, silinganisa ulawulo lwe-thermal ukuya kweyona ndawo ibandayo kwisakhiwo.
