Lithium batari phosphate bir ah, sifooyinka, codsiga

qalab casri ah maalin kasta ayaa noqonaya mid aad u adag oo awood leh. heerka technology Sare u sameeyaan dalabyada sare si ay u baytariyo in haatan u baahan tahay in la isu geeyo waxqabadka sare, tamarta, iyo waxay leeyihiin sahayda dheeraad ah oo koronto ah.

hordhaca ah ee noocyada cusub ee wax soo saarka qalabka korontada, xawaaraha ee geedi - waxan oo dhan ayaa waxay kordhisaa baahida korontada, iyo batariyo casriga ah mar dambe had iyo jeer la kulmaan iyagii karo. Si loo xalliyo dhibaatada this, saarayaasha doortay si ay kor ugu technology lithium-ra'iyi. Sayidka ayaa ku dhashay ee batari phosphate bir lithium (LiFePO4), taas oo ah farac ah fikirka ah baytariyada Li-ra'iyi.

macluumaadka taariikhiga ah

LiFePO4, ama LFP, - qoyska olivine macdanta dabiiciga ah, markii ugu horaysay la helay in 1996 by saynisyahano oo ka tirsan jaamacadda Texas, John Goodenough, kuwaas oo la doonayo si loo hagaajiyo ilaha awooda ee Li-ra'iyi. Caan ah waa xaqiiqada ah in macdanta leeyahay sumoobo hoose iyo xasiloonida sare kaamerada wax loo yaqaan waqtiga electrodes ah.

Ka sokow waxaa ku kulmay deegaanka dabiiciga ah, oo waxay lahaayeen qiimo jaban. khasaare ugu weyn ee electrodes ee ku saleysan LiFePO4 ahaa awoodda yar ee korontada, taas oo ah sababta lithium batari phosphate birta ayaa joojiyeen in allabaryo la horumariyo.

Research jihada this ayaa dib u bilaabay sanadkii 2003 machadka Massachusetts ee Technology. Koox Seynis yahanno ka shaqeeya abuurista batari aasaas cusub oo noqon lahaa bedel ah ugu horumarsan at in baytariyada mar, Li-ra'iyi. Mashruuca ayaa xiiseynaya in shirkadaha waawayn ee sida Motorola iyo Qualcomm ee, kaas oo keenay bixitaanka batari waxyaabaha cathode LiFePO4.

LiFePO4 batari ku saleysan

Noocan ah baytariyada isticmaalaa technology isla si loo soo saaro koronto, iyo unugyada lithium-ra'iyi caadiga ah inoo ah. Si kastaba ha ahaatee, waxaa jira tiro ka mid ah farqi weyn oo u dhaxeeya. First, waa in la isticmaalo ay tahay nooca gaarka ah ee BMS - nidaamka maamulka ilaaliya batteriga korontada ka overcharging iyo dheecaan qoto dheer, hagaajinaysaa cimri dherer iyo dhigaysa ilaha tamarta ka xasilloon.

Marka labaad, LiFePO4, ka duwan LiCoO2, waa wax ka yar sunta ah. Dhab ahaantii Tani waxay ogol yahay in ay ka fogaadaan qaar ka mid ah dhibaatooyinka la xiriira wasakhaynta deegaanka. Gaar ahaan si loo yareeyo qiiqa Cobalt sabab u ah qashin aan habboonayn ee bateriga.

Ugu dambayntii, ay sabab u la'aanta ah ee heerarka midaysan xubno LFP leeyihiin darey kiimiko kala duwan, kaas oo keena in lagu daydo Performance kala duwanaansho badan ballaaran oo kala duwan. Intaa waxaa dheer, kuwaas oo awood u dayactirka agabka dhib badan iyo waa in la sameeyaa hab waafaqsan xeerarka qaarkood.

astaamaha farsamo

Waxaa la sheegay in birta lithium batari phosphate 48 volts, 36 volts iyo 60 volts waxa soo saarey sequentially interconnecting unugyada hal, maxaa yeelay, danab ugu badan ee hal LFP-qaybta laga yaabaa in aan ka badnayn 3.65m V. Sidaa darteed, waxqabadka batari kasta si weyn waxaa laga yaabaa ku kala duwan yihiin midba midka kale - waxa ay ku xiran shirka iyo Halabuurka kiimikada gaar ah.

Waayo, Performance falanqaynta soo bandhigaan qiimaha magacaaban mid hal unug.

xaqiijinta ugu wanaagsan ee iman kara ee unug kasta oo gaar ah in batteriga ayaa gaaray Everexceed. Lithium batari phosphate bir ah ku kala duwan yihiin Everexceed cimri dheer. Dhammaan waxay u adkeysan karaan ilaa 4 kun oo wareegyada Charge-dheecaan. Khasaara ah oo awood ah ilaa 20%, iyo badalkooda ee kaydinta tamarta meel 12 daqiiqo. Marka la eego this, waxaannu ku tirinnaa karaa in baytariyada Everexceed waa mid ka mid ah wakiilada ugu fiican ee LFP xubno.

Faa'iidada iyo faa'iido darrada

Faa'iidada ugu weyn ee in iftiinka wanaagsan muujineysaa batari phosphate bir lithium ah, ka mid ah wakiilada kale ee CRA ah, waa socdeyba. element noocan oo kale ah waa in ay u adkeysan ka badan 3 kun oo wareegyada kharash-dheecaan heer awood awoodi dhaco 30%, iyo in ka badan 2 kun - .. Haddii hoos ilaa 20%. Taas darteed nolosha batteriga celcelis ahaan waa qiyaastii 7 sano.

hadda ku amraya deggan waa faa'iido labaad muhiimka ah ee LFP-xubno. danab saarka ayaa weli loo siman yahay 3.2 V ilaa ay amarka u gebi ahaanba daalay. Tani nayaa xarkaha, baabi'inta baahida loo qabo nidaamiyo danab.

Higher ugu sarreysa hadda - saddexaad ee ay ka faa'iidaystaan. Habkaani wuxuu kuu ogolaanayaa batteriga inaad iyaga siinaysid awood badnaan xataa marka heerkulku aad u yar yahay. hantida Tani waxa ay keentay in saarayaasha gaari si ay u isticmaalaan lithium batari phosphate bir ah isha ugu awood hoose marka laga bilaabo baatrool iyo naaftada matoorada.

Wada jir ah ula faa'iidooyinka oo dhan, bateriga LiFePO4 leeyihiin hal khasaare weyn - mass weyn oo dhinacyada. Tani waxay xad u isticmaalkooda in noocyo ka mid ah mashiinada iyo qalabka korontada.

Features ee hawlgalka

Haddii aad ka iibsan batariyada lithium-phosphate diyaar-dhigay, dhibaatooyinka la dayactirka iyo hawlgal ma waxaad yeelan doontaa. All mahad xaqiiqada ah in soo saarayaasha xubno sida la geliyo galay guddiga BMS in looga hortago overcharging iyo ka hortagga element dheecaan in heerka ugu hooseeya.

Laakiin haddii aad iibsato unugyada shaqsi (baytariyada penlight, tusaale ahaan), ka dibna aad leedahay si ay isha ku hay awood batari oo keliya. Marka lacag hoos uga dhaco heerka muhiim ah (2.00 V hoose) si degdeg ah dhici doonaan iyo capacitance, taas oo aan macquul ahayn ku nasto unugyada. Haddii aad, on lid ku ah, la cuslaan (kor ku xusan 3.75 V), gacanta si fudud kurtimaha sabab u ah gaasaska la sii daayay.

Haddii aad isticmaalayso batari noocan oo kale ah, waayo, gaariga korontada, ka dib markii 100% ku amraya waa in aad barkinta xeedho batteriga. Haddii kale, batteriga Biyana ay sabab u tahay supersaturation of koronto.

xeerarka hawlgalka

Haddii aad qorsheyneysid inaad isticmaasho a batari lithium-phosphate in hab xilliile ah iyo kayd ah, tusaale ahaan, sida il awoodeed-ups ama lala batari qoraxda, waxaad u baahan tahay in ay is ogow of hoos heerka la'aan in 3.40-3.45 V. qabsadaan hawshan ka caawisaa saxan 'smart' in si toos ah ugu horeysay si buuxda u buuxin karaan sahayda tamarta, ka dibna hoos u heer walwalka.

Inta lagu jiro hawlgalka, waxaad u baahan tahay si ay ula socdaan dheelitirka ee unugyada ama isticmaalka lacagta shey gaar ah (in batteriga, waxay u dhisay baabuur koronto). dheelitir la'aanta gacanta loo yaqaan gobolka noocan oo kale ah, marka danab guud ee qalabka waa heer magacaaban, laakiin danab cell wuxuu noqonayaa kala duwan.

Tani waxay ifafaale waxaa sabab u ah kala duwanaanshaha u ah resistances ee qaybaha shaqsi, therebetween xiriir saboolka ah. Haddii unugyada ay leeyihiin voltages kala duwan, iyo waa ay sinnayn kharash-dheecaan, taas oo si weyn u yaraynaysaa nolosha adeeg ee batteriga ah.

Habeynta batteriga galay hawlgalka

Ka hor inta la isticmaalayo phosphate lithium ka unugyada gaar ah soo ururay batariyo, daryeelka waa in loo qaato nidaamka miisaamid, sida qaybaha yeelan karaan heerka mas'uul oo kala duwan. Ujeedada this dhan ka kooban yihiin isku xidhan ee isku midka ah iyo ku xiran yihiin rectifier ah, xeedho. United sidaas waxaa lagama maarmaan ah in ay ka qaadaan gacanta in 3.6 V.

Isticmaalka batari phosphate bir lithium for baaskiil korontada, laga yaabaa inaad dareentay in daqiiqadii ugu horeysay ee batari ku siinayaa awood ay ugu badnaan, ka dibna amarka si degdeg ah ku dhacaan heerka of 3.3-3.0 V. Ha cabsan of this, maxaa yeelay, waa hawlgalka caadiga ah ee batteriga . Xaqiiqada ah in inta badan ay awood (qiyaastii 90%) been kala duwan this.

gunaanad

Karti batariyada lithium-phosphate waa 20-30% ka sarreeya in bateriga kale. Isla mar ahaantaana ay u adeegi 2-3 sano muddo ka badan ilo kale awood, iyo sidoo kale ku siin hadda deggan muddo dhan hawlgalka. All this ay muujineysaa xubno lagu soo bandhigay iftiin wanaagsan.

Si kastaba ha ahaatee, inta badan dadka iska indha doonaa iyo batari phosphate bir lithium. Faa'iidada iyo khasaaraha of batari caddaan ka hor inta ay qiimaha - waa 5-6 jeer ka badan intii caadiga ahayd ee noo horseedi-acid unugyada. batari gaari tani waxay celcelis ahaan ku saabsan 26 kun. rubles.
