Uxinano lwamandla ebhetri yeLithium-ion luphezulu, ngenxa yezizathu zokhuseleko umthamo oqhelekileyo awuyi kuyilwa ukuba ube mkhulu kakhulu, kodwa inani leeseli ze-lithium zentsimbi ze-phosphate ngokusebenzisa izihlanganisi eziqhubekileyo kuluhlu kunye nokuhambelana nombane, ukwenza imodyuli yebhetri ye-lithium yelanga. , nangona kunjalo, oku kufuneka kujongane nengxaki yokuhambelana.
Ukungangqinelani kweibhetri lithium yelangaiiparamitha zihlala zibandakanya umthamo, ukuchasana kwangaphakathi, ukungahambelani kombane ovulekileyo, ukungahambelani kokusebenza kweseli yebhetri, eyenziwe kwinkqubo yokuvelisa, iya kuba mbi ngakumbi kwinkqubo yokusetyenziswa, ipakethe yebhetri efanayo ngaphakathi kweseli, ubuthathaka ihlala ibuthathaka kwaye ikhawulezisa ukuba buthathaka kunye nenqanaba lokusasazwa kweeparamitha phakathi kweseli ye-monomer, kunye nokunyuka kweqondo lokuguga kwaye libe likhulu.
Ufundo olunxulumeneyo: Yintoni iSolar Lithium yeBattery Consistency?
Eli nqaku liza kwazisa iiseli ezingahambelaniyo xa zisetyenziselwa uchungechunge kunye kunye, yintoni ingozi eya kuziswa kwi-lithium-ion battery PACK kunye nendlela esifanele sijongane ngayo nengxaki yeebhetri ze-lithium zelanga ezingahambelaniyo.
Zeziphi iingozi zeebhetri zeSolar Lithium ezingahambelaniyo?
Ukulahleka komthamo wokugcina we-solar lithium battery pack
Kuyilo lwe-solar lithium battery pack, umthamo wonke uhambelana "nomgaqo we-barrel", umthamo we-lithium yensimbi ye-phosphate eyingozi kakhulu imisela umthamo wepakethi yebhethri ye-solar ye-lithium. Ukuze kuthintelwe ukutshaja kakhulu kunye nokukhupha ngaphezulu, inkqubo yolawulo lwebhetri iya kuthatha le ngqiqo ilandelayo:
Xa ukhulula: xa i-voltage ephantsi yeseli enye ifikelela kumbane wokukhupha ukukhutshwa, yonke ipakethe yebhetri iyayeka ukukhupha;
Ngexesha lokutshaja: xa owona mbane uphezulu wombane uchukumisa umbane onqunyiweyo wokutshaja, ukutshaja kuyamiswa.
Ukongeza, xa umthamo omncinci weseli yebhetri usetyenziswa kuthotho kunye neseli enkulu yebhetri, umthamo omncinci weseli yebhetri uya kuhlala ukhutshwa ngokupheleleyo, ngelixa iseli enkulu yebhetri iya kuhlala isebenzisa inxalenye yomthamo wayo, okukhokelela kumthamo webhetri. yonke ipakethe yebhetri isoloko inenxalenye yomthamo wayo kwimeko yokungenzi nto.
Ukunciphisa ubomi bokugcinwa kweepakethi zebhetri ze-lithium zelanga
Ngokufanayo, ubomi be-aibhetri yelanga lithiumixhomekeke kwiseli ye-lithium iron phosphate enobomi obufutshane. Kusenokwenzeka ukuba iseli enexesha elifutshane lokuphila yiseli ye-lithium iron phosphate enomthamo ophantsi. Umthamo ophantsi we-LiFePO4 iseli kunokwenzeka ukuba ibe yeyokuqala ukufikelela ekupheleni kobomi bayo kuba ihlawuliswa ngokupheleleyo kwaye ikhutshwe rhoqo. Xa idityaniswe njengeqela leeseli ze-lithium iron phosphate ekupheleni kobomi, yonke i-solar lithium battery pack nayo iya kulandela isiphelo sobomi.
Ukonyuka kokuchasana kwangaphakathi kweepakethi zebhetri zelanga
Xa umbane ofanayo uhamba ngeeseli ezineendlela ezahlukeneyo zokuchasana kwangaphakathi, iseli ye-LiFePO4 enokumelana okuphezulu kwangaphakathi ivelisa ubushushu obuninzi. Oku kukhokelela kwiqondo lokushisa eliphezulu leeseli zelanga, elikhawulezisa izinga lokuwohloka kunye nokwandisa ukuchasana kwangaphakathi. Isibini seempendulo ezingalunganga zenziwa phakathi kokuchasana kwangaphakathi kunye nokunyuka kweqondo lokushisa, okukhawulezisa ukuwohloka kweeseli ezinokumelana okuphezulu kwangaphakathi.
Ezi parameters zintathu zingasentla azizimele ngokupheleleyo, kwaye iiseli ezikhulileyo zinokumelana okuphezulu kwangaphakathi kunye nokuthotywa kwamandla amaninzi. Nangona ezi parameters zichaphazela omnye komnye, kodwa ngokwahlukeneyo zichaza impembelelo yazo, zincede ukuqonda ngcono ubungozi bokungangqinelani kwebhetri ye-lithium yelanga.
Ukujongana njani nokungangqinelani kwebhetri yeSolar yeLithium?
Ulawulo lweThermal
Ekuphenduleni ingxaki yokuba iiseli ze-lithium iron phosphate kunye nokuchasana kwangaphakathi okungahambelaniyo zenza amanani ahlukeneyo okushisa, inkqubo yokulawula i-thermal ingabandakanywa ukulawula ukuhluka kweqondo lokushisa kuyo yonke ibhetri ye-packpake ukwenzela ukuba umehluko weqondo lokushisa ugcinwe ngaphakathi kwinqanaba elincinci. Ngale ndlela, nokuba iseli evelisa ubushushu obuninzi isenobushushu obuphezulu bokunyuka, ayizukusuka kwezinye iiseli, kwaye inqanaba lokuwohloka aliyi kwahluka kakhulu. Iinkqubo eziqhelekileyo zolawulo lwe-thermal ziquka i-air-cooled kunye ne-liquid-cooled systems.
Ukuhlela
Injongo yokuhlela kukwahlula iiparitha ezahlukeneyo kunye neebhetshi zelithium yesinyithi iphosphate iiseli zebhetri ngokukhetha, nokuba ibhetshi efanayo yelithium yesinyithi iphosphate iiseli zebhetri, kodwa kufuneka kwakhona ihlolwe, iparameters yoxinaniso lwelithium iron phosphate battery. iiseli kwibhetri pack, ibhetri Pack. Iindlela zokuhlela ziquka ukuhlela okumileyo kunye nokuhlelwa okuguquguqukayo.
Ukulingana
Ngenxa yokungahambelani kweeseli ze-lithium iron phosphate, i-terminal voltage yezinye iiseli iya kuba ngaphambi kwezinye iiseli kwaye ifike kumda wolawulo kuqala, okukhokelela ekubeni umthamo wenkqubo yonke ube mncinci. Umsebenzi wokulinganisa wenkqubo yokulawula ibhetri i-BMS inokusombulula le ngxaki kakuhle kakhulu.
Xa iseli yebhetri ye-lithium yentsimbi ye-phosphate yeyokuqala ukufikelela kwi-voltage yokutshaja enqunyulwe, ngelixa lonke i-lithium yentsimbi ye-phosphate ibhetri ye-voltage yebhetri isemva, i-BMS iya kuqalisa umsebenzi wokulinganisa ukutshaja, okanye ukufikelela kwi-resistor, ukukhupha. inxalenye yamandla aphezulu-voltage lithium yentsimbi phosphate ibhetri cell, okanye ukudlulisa amandla kude kwi-low-voltage lithium yentsimbi phosphate ibhetri cell up. Ngale ndlela, imeko yokucima ukutshaja iphakanyisiwe, inkqubo yokutshaja iqala kwakhona, kwaye ipakethe yebhetri inokuhlawuliswa ngamandla amaninzi.
