Intshayelelo:
Iibhetri zeLithium zikho kuyo yonke indawo ebomini bethu. Iibhetri zethu zefowuni eziphathwayo kunye neebhetri zemoto yombane zonke zikhoiibhetri ze-lithium, kodwa ngaba uyazi amagama asisiseko ebhetri, iintlobo zebhetri, kunye nendima kunye nomahluko wochungechunge lwebhetri kunye noqhagamshelo oluhambelanayo? Makhe sihlolisise ulwazi lweebhetri ngeHeltec.
Isigama esisisiseko seebhetri ze-lithium
1) Ireyithi ye-C
Ibhekisa kumlinganiselo wamandla angoku kumthamo oqhelekileyo webhetri ye-lithium ngexesha lokutshaja nokukhupha ibhetri. Ichaza ukuba ibhetri inokutshaja nokukhupha ibhetri ngesantya esingakanani. Amanqanaba okutshaja nokukhupha ibhetri awafani ngokuyimfuneko. Umzekelo:
1C: khupha ibhetri ngokupheleleyo kwisithuba seyure e-1 (itshaja epheleleyo)
0.2C: khupha ibhetri ngokupheleleyo kwiiyure ezi-5 (itshaja epheleleyo)
5C: khupha ibhetri ngokupheleleyo zingadlulanga iiyure eziyi-0.2 (itshaja epheleleyo)
2) Umthamo
Ubungakanani bombane ogcinwe kwiibhetri ye-lithiumIyunithi yi-mAh okanye i-Ah.
Xa idibene nesantya, umzekelo, ukuba ibhetri yi-4800mAh kwaye isantya sokutshaja siyi-0.2C, oko kuthetha ukuba kuthatha iiyure ezi-5 ukuba ibhetri itshajwe ngokupheleleyo xa ingenanto (ukungahoyi inqanaba lokutshaja kwangaphambili xa ibhetri iphantsi kakhulu).
Umsinga wokutshaja ngu: 4800mA*0.2C=0.96A
3) Inkqubo yolawulo lwebhetri ye-BMS
Le nkqubo ilawula kwaye ilawula ukutshaja/ukukhupha ibhetri, ibona ubushushu kunye nevolthi yebhetri, iqhagamshelane nenkqubo yomninimzi, ilinganisele ivolthi yebhetri, kwaye ilawula ukusebenza kokhuseleko lwepakethi yebhetri ye-lithium.
4) Umjikelo
Inkqubo yokutshaja nokukhupha ibhetri ibizwa ngokuba yi-cycle. Ukuba ibhetri isebenzisa kuphela i-80% yamandla ayo ewonke ngalo lonke ixesha, ubomi bomjikelo weebhetri ze-lithium-ion bunokuba phezulu kangangezihlandlo ezingamawaka.
Uhlobo lwebhetri yeLithium
Okwangoku, iiseli ze-lithium-ion zorhwebo ikakhulu zisilinda, zisikwere kwaye zithambile.
Iiseli ze-cylindrical eziyi-18650 ziiseli ze-lithium-ion ezinemveliso ephezulu okwangoku. Iiseli zethu zebhetri ze-G series monitor zezo hlobo.
Uthotho lweeseli kunye noqhagamshelo oluhambelanayo
Iseli yinxalenye ephambili ye-ibhetri ye-lithiumInani leeseli liyahluka ngokuxhomekeke ekusetyenzisweni kwebhetri, kodwa zonke iibhetri kufuneka ziqhagamshelwe ngeendlela ezahlukeneyo ukuze kufezekiswe i-voltage kunye namandla afunekayo.
Qaphela: Iimeko zoqhagamshelo oluhambelanayo zinzima kakhulu. Ke ngoko, uqhagamshelo oluhambelanayo kuqala uze uqhagamshele ngochungechunge lunokunciphisa iimfuno zokuqina kwebhetri.
Q: Yintoni umahluko phakathi kweebhetri ezi-three-series kunye nezi-four-parallel kunye nezi-four-parallel kunye nezi-three-series?
A: I-voltage kunye nomthamo zahlukile.Uqhagamshelo lwechungechunge lonyusa i-voltage, kwaye uqhagamshelo oluhambelanayo lonyusa i-current (umthamo)
1) Uqhagamshelo oluhambelanayo
Masithi i-voltage yeseli yebhetri yi-3.7V kwaye umthamo wayo yi-2.4Ah. Emva koqhagamshelo oluhambelanayo, i-voltage yesiphelo senkqubo iseyi-3.7V, kodwa umthamo wayo uyanda uye kwi-7.2Ah.
2) Uqhagamshelo lothotho
Masithi i-voltage yeseli yebhetri yi-3.7V kwaye umthamo wayo yi-2.4Ah. Emva koqhagamshelo olulandelelanayo, i-voltage yesiphelo senkqubo yi-11.1V, kwaye umthamo awutshintshi.
Ukuba iseli yebhetri iluhlu lwesithathu kunye nezimbini ezilinganayo, zizonke ziiseli eziyi-6 18650, ngoko ke ibhetri yi-11.1V kunye ne-4.8Ah. I-sedan yeTesla Model-S isebenzisa iiseli zePanasonic 18650, kwaye ibhetri ye-85kWh ifuna malunga neeseli eziyi-7,000.
