Cov nqi sawv cev rau kev sib piv xwb; xyuas kom meej cov ntaub ntawv ntawm koj tus neeg muab khoom xov tooj ntawm tes rau cov kev txwv tiag tiag.
Yuav Xav Li Cas Txog Qhov Kev Xaiv
LiFePO4— qhov qub rau feem ntau ntawm cov chaw cia khoom hauv tsev thiab chaw ua lag luam.
Muaj kev sib npaug zoo ntawm kev nyab xeeb, lub neej ntev, thiab tus nqi. Yog tias koj tsis muaj laj thawj xaiv lwm yam, LiFePO4 feem ntau yog qhov pib.
NMC— thaum lub zog ceev thiab compactness tseem ceeb tshaj plaws.
Lub zog ceev dua hauv lub pob me dua, sib dua, ntawm tus nqi tsawg dua cov voj voog thiab kev tswj hwm thermal nruj dua.
LTO— rau lub neej voj voog ntev heev, them sai, thiab qhov kub thiab txias dav.
Ib qho kev xaiv tshwj xeeb tab sis ruaj khov uas lub neej ntev thiab qhov kub thiab txias ntau dua li qhov ceev ntawm lub zog. →Xaiv BMS rau LTO.
Sodium-ion— ib qho kev xaiv tshiab rau huab cua txias thiab kev sib txawv ntawm cov khoom siv.
Kev coj cwj pwm kub qis thiab kev xa khoom sib txawv, nrog rau lub ecosystem uas tab tom loj hlob. →Xaiv BMS rau sodium-ion.
Txhua Chemistry Txhais Li Cas rau BMS
Txawm koj xaiv hom tshuaj twg los xij, BMS yuav tsum tau teeb tsa rau nws:
Cov kev tiv thaiv.
Over-voltage, under-voltage, thiab kev sib npaug txwv txawv ntawm chemistry - BMS teeb tsa rau ib qho chemistry yuav tiv thaiv lwm qhov tsis raug.
Suav cov koob.
Vim tias qhov voltage ntawm lub cell nominal txawv, tus naj npawb ntawm cov cell hauv series rau lub hom phiaj pob voltage hloov pauv - LTO xav tau feem ntau cov cell, NMC tsawg tshaj plaws, rau tib lub voltage.
Kev kwv yees ntawm lub xeev them nqi.
SOC nyeem los ntawm cov tshuaj lom neeg tus kheej voltage curve; siv cov curve tsis raug qhia txog qib them tsis raug.
DALY: Ib Tus Khub BMS Thoob Plaws Plaub Lub Tuam Txhab Tshuaj
DALY tsim cov tshuab tswj roj teeb rauLiFePO4, NMC, LTO, thiab sodium-ionCov kev tiv thaiv thresholds, series suav, lub xeev-ntawm-charge kwv yees, thiab kev sib npaug yog teeb tsa rau koj lub cell tshwj xeeb - yog li koj tuaj yeem ua tus qauv rau ib tus khub BMS hla ntau yam tshuaj lom neeg. Xa koj daim ntawv qhia txog lub cell thiab pob tsim, thiab pab pawg engineering DALY yuav lees paub qhov kev teeb tsa raug rau koj cov tshuaj lom neeg xaiv.
Cov Lus Nug Feem Ntau
Q1Cov tshuaj twg zoo tshaj plaws rau kev khaws cia lub hnub ci hauv tsev?
LiFePO4 yog qhov kev xaiv tseem ceeb rau nws qhov kev sib npaug ntawm kev nyab xeeb, lub neej voj voog, thiab tus nqi. NMC, LTO, thiab sodium-ion haum rau qhov tseem ceeb tshwj xeeb - compactness, lub neej ntev / kub heev, lossis huab cua txias thiab kev muab khoom sib txawv.
Q2Ib lub BMS puas tuaj yeem tswj cov tshuaj sib txawv?
Yuav tsum teeb tsa BMS rau cov tshuaj tshwj xeeb - nws qhov txwv, suav cov koob, thiab SOC nkhaus. Tus neeg muab khoom tib yam tuaj yeem muab BMS rau cov tshuaj sib txawv, tab sis txhua pob BMS tau teeb tsa rau nws tus kheej lub cell.
Q3Vim li cas chemistry thiaj hloov tus naj npawb ntawm cov cell hauv series?
Txhua lub tshuaj muaj lub zog hluav taws xob sib txawv, yog li ntawd, kev ncav cuag lub hom phiaj pob hluav taws xob siv tus lej sib txawv ntawm cov hlwb - piv txwv li LTO (~ 2.3V) xav tau ntau lub hlwb dua li LiFePO4 (~ 3.2V) rau tib lub zog hluav taws xob.
