Ipakethi yebhetri ye-lithium iron phosphateithandwa ngabalandeli abaninzi ngenxa yobunzima bayo obukhaphukhaphu phantsi komthamo ofanayo, umthamo webhetri ye-lithium yenye yezalathisi ezibalulekileyo zokusebenza ukulinganisa ukusebenza kwebhetri, xa ikhutshwa, i-voltage yebhetri ye-lithium iya kuncipha ngokuthe ngcembe ngokuhamba kwebhetri. amandla, kwaye kukho ithambeka elikhulu.Eli phepha liza kusombulula imfihlakalo yombane kunye nomthamo webhetri ye-lithium iron phosphate.
1) Umthamo webhetri ye-lithium iron phosphate:
Umthamo wokupakisha ibhetri yeLithium yenye yezalathisi ezibalulekileyo zokusebenza ukulinganisa ukusebenza kwebhetri, ibonisa amandla akhutshwe yibhetri phantsi kweemeko ezithile (izinga lokukhutshwa, ubushushu, i-voltage yokuphela, njl.) (inokusebenzisa i-JS-150D yokukhupha uvavanyo), oko kukuthi, umthamo webhetri, ngokuqhelekileyo kwiiyure.Umthamo webhetri ye-lithium uhlukaniswe ube ngumthamo wangempela, umthamo wethiyori kunye nomthamo olinganisiweyo ngokweemeko ezahlukeneyo.Ifomyula yokubala umthamo webhetri C yi-C= t0It1dt, kwaye ibhetri yahlulwe ibe yi-electrode ekhayo kunye ne-negative.

2) Ibhetri ye-lithium iron phosphate:

Ibhetri ye-lithium ye-iron phosphate ibhekisela kwibhetri ye-lithium-ion usebenzisa i-lithium iron phosphate njenge-cathode material.Izixhobo ze-cathode ze-lithium ion ibhetri ziquka i-lithium cobalt oxide, i-lithium manganese oxide, i-lithium nickel acid, izinto ze-ternary, i-lithium iron phosphate njalo njalo. .
Umbane wokutshaja wepakethi yebhetri ye-lithium ye-iron phosphate kufuneka ibekwe ku-3.65v, amandla ombane angama-3.2v, owona mbane uphezulu wokutshaja unokuba ngama-20% aphezulu kunombane oqhelekileyo, kodwa umbane uphezulu kakhulu ukonakalisa ibhetri, umbane oyi-3.6v ngaphantsi kwesi salathiso, akukho ntlawulo egqithisileyo.Ipakethi yebhetri yeLithium ukuba ibeka ubuncinane be-3.0v kufuneka ihlawule, ngoko i-3.4v kunobuncinane be-0.4v, i-0.6v kune-0.6 v inokukhulula isiqingatha samandla, oko kukuthi, yonke intlawulo, ngaphezu kwexesha lokusebenzisa i-3.4v, ngenxa yokuba amaxesha okusebenzisa ibhetri, ngoko ubomi banda ngesiqingatha, ngoko ke kwimeko yokungonakalisi ibhetri, ukwandisa umbane wokutshaja, kuya kwandisa ubomi bebhetri ye-lithium.

3) Yintoni ubudlelwane phakathi kombane wokupakisha kunye nomthamo webhetri ye-lithium iron phosphate pack?
Ngokuqhelekileyo, okukhona intlawulo ephezulu kunye nokukhupha amandla ombane we-lithium iron phosphate battery pack, kokukhona umthamo wayo mkhulu.Umthamo wokutshaja kunye nokukhutshwa kwamandla ebhetri ye-lithium yezinto ezahlukeneyo yahlukile, kwaye eyona iphantsi yibhetri ye-lithium ye-iron phosphate. Njengoko umthamo iyancipha, i-voltage iyancipha, kwaye umthamo uncinci xa i-voltage ingaphantsi kokulinganisa.
1. Kwibhetri efanayo, kunye nomthamo ofanayo wokushiyeka, ixabiso le-voltage liyahluka ngenxa yobukhulu be-discharge current.Iphezulu i-discharge current, i-voltage ephantsi.Ngokungabikho kombane wangoku, i-voltage ephezulu ikhona. .
2. Impembelelo yobushushu be-ambient kwi-lithium battery pack voltage.Okukhona usezantsi ubushushu, kokukhona usezantsi amandla ombane ebhetri umthamo ofanayo.
3. Impembelelo yomjikelezo kwiqonga lokukhupha ibhetri.Njengoko umjikelo uqhubeka, iqonga lokukhutshwa kwebhetri ye-lithium-ion livame ukuhla.
4. Abavelisi abahlukeneyo, umthamo ohlukeneyo weebhetri ze-lithium ion, iiplatifti zabo zokukhupha ezihlukeneyo.
5. Iqonga lokukhutshwa kweentlobo ezahlukeneyo zezinto ze-electrode zihluke kakhulu.I-lithium cobalt kunye ne-manganese i-lithium discharge platforms zihluke ngokupheleleyo.
Konke oku kuya kubangela ukuguquguquka kwamandla ombane kunye nomahluko wombane, ukwenza umthamo webhetri ye-lithium ye-phosphate ibonakaliswe.

Umthamo webhetri ye-lithium ubhekisela kubungakanani bebhetri yokugcina amandla.I-voltage ye-lithium iron phosphate battery pack iye yancipha ngexesha lenkqubo yokukhupha, njengebhetri 3.6v, 19ah, 19ah umthamo awufakwanga kwi-0v, kodwa 2. eziliqela. okanye 3. Xa, umthamo wokukhutshwa ngu-19ah, ukuba ubeka kwi-0v, umthamo uya kuba ngaphezu kwe-19, ubeka kakhulu, uya kuwonakalisa ubomi bebhetri.

Oku kungasentla lubudlelwane phakathi kwe-lithium yentsimbi ye-phosphate yebhetri ye-voltage yombane kunye nomthamo, xa kungekho yangoku, i-voltage iphezulu, iqondo lokushisa eliphantsi, liphantsi lombane womthamo ofanayo webhethri ye-lithium.Ngokuthetha ngokubanzi, phezulu I-voltage ye-lithium ye-iron phosphate ye-lithium ye-iron phosphate, okukhona umthamo wayo mkhulu.
