Intshayelelo:
Iibhetri zeLithium zikho naphi na ebomini bethu. Iibhetri zethu zefowuni kunye neebhetri zemoto yemoto zonkeIibhetri ze-lithium, kodwa ngaba uyayazi imigaqo ethile yebhetri, iintlobo zebhetri, kunye nendima yomahluko webhetri kunye noqhagamshelo olufanayo? Masihlole ulwazi lweebhetri nge-Heltec.
Isigama esisisiseko seebhetri zeLithium
1) I-C-Area
Ibhekisa kumyinge we-OKUKHO BOKUGQIBELA WOKUGQIBELA WOKUGQIBELA WAMABHUNGA LE-LINIIM ngexesha lokubiza kunye nokuyeka. Ichaza ukuba ibhetri ingahlawuliswa njani kwaye ikhutshiwe. Ukutshaja kunye nokugcuma kwamaxabiso ayifani. Umzekelo:
I-1c: Ukukhupha ngokupheleleyo ibhetri kwiyure enye (intlawulo epheleleyo)
I-0.2C: Ukukhupha ngokupheleleyo ibhetri ngaphakathi kweeyure ezi-5 (intlawulo epheleleyo)
I-5c: Ukukhupha ngokupheleleyo ibhetri ngaphakathi kwe-0.2 iiyure (intlawulo epheleleyo)
2) Umthamo
Ubungakanani bombane obugcinwe kwiIbhetri yeLithium. Iyunithi yi-mah okanye i-ah.
Idityaniswa ngexabiso, umzekelo, ukuba ibhetri ingama-4800ma kunye nenqanaba lokutshaja ngu-0.2c, kuthetha ukuba kuthatha i-5 yeeyure zebhetri xa ibhetri iphantsi kakhulu).
Ukutshaja okwangoku: 4800MA * 0.2c = 0.96A
I-3) Inkqubo ye-BMS yebhetri
Inkqubo ilawula kwaye ilawule i-shartage / ikhutshiwe ibhetri, ifumanisa ubushushu bebhetri, iqhagamshela kwinkqubo yebhetri, idibanisa ukusebenza kwebhetri, kwaye ilawula i-voltage yebhegi yebhetri.
4) Umjikelo
Inkqubo yokutshaja kwebhetri kunye nokukhupha ibizwa ngokuba ngumjikelo. Ukuba ibhetri isebenzisa kuphela i-80% yamandla ayo apheleleyo rhoqo, umjikelo wobomi beLithium-ion unokuba phezulu kumawaka amaxesha.
Uhlobo lwebhetri yeLithium
Okwangoku, iiseli ze-lithium-ze-ion-ion ikakhulu ziyi-cylindrical, isikwere kunye nepakethe ethambileyo.
Iiseli ezili-18650 zeCylindrical Cylindrical ziiseli ze-lithium-i-ion kunye neyona mveliso iphakamileyo yemveliso okwangoku. Ungcelele lwe-G lethu lokubeka iliso kwi-CEBTE ze-CEBT zolu hlobo.
Uthotho lweseli kunye nonxibelelwano olufanayo
Iseli yeyona nto iphambili kwiIbhetri yeLithium. Inani leeseli liyahluka ngokuxhomekeka ekusetyenzisweni kwebhetri, kodwa zonke iibhetri kufuneka zidityaniswe ngeendlela ezahlukeneyo zokufezekisa i-voltage efunekayo kunye namandla.
QAPHELA: Iimeko zonxibelelwano olufanayo zithwele kakhulu. Ke ngoko, uqhagamshelo olufanayo kuqala kwaye uqhagamshelo olunokuphucula iimfuno zokungqinelana kwebhetri.
Q: Nguwuphi umahluko phakathi kweendlela ezintathu kunye ne-ezine-ezifanayo kunye neebhetri ezifanayo kunye neebhetri zendlela ezintathu?
A: I-voltage kunye nomthamo wahlukile.Uqhagamshelo lochurichunge lokonyusa i-voltage, kunye noqhagamshelo oluhambelanayo lunyuka ngoku (umthamo)
1) Unxibelelwano olufanayo
Cinga ukuba i-voltage yeseli yebhetri yi-3.7v kunye nesikhundla yi-2.4ah. Emva konxibelelwano olufanayo, i-terminal voltage yenkqubo ise-3.7v, kodwa amandla anyuka kwi-7.2ah.
2) uqhagamshelo
Cinga ukuba i-voltage yeseli yebhetri yi-3.7v kunye nesikhundla yi-2.4ah. Emva koqhagamshelo loqhagamshelo, i-terminal voltage yenkqubo yi-11.1v, kwaye umthamo uhlala engaguqukanga.
Ukuba iseli yebhetri nguchungechunge amathathu kunye nobabini ngokufanayo, zizonke iiseli ezingama-6 18650, emva koko ibhetri ngu-11.11v no-4.8h. I-Tessala imodeli yeTessa isebenzisa iPanasonic 18650 iiseli, kunye nepakethi ye-85kww yebhetri ifuna malunga neeseli ezingama-7000.
Ukuqukumbela
I-Heltec iya kuqhubeka nokuhlaziya ulwazi lwesayensi oludumileyo malungaIibhetri ze-lithium. Ukuba unomdla, unganikela ingqalelo kuyo. Kwangelo xesha, sikunika iipakethi ze-lithium ezikumgangatho ophezulu kuwe ukuba uthenge kwaye ubonelele ngeenkonzo ezenziwe ngokwezifiso ukuze uhlangabezane neemfuno zakho.
Amandla eHestec liqabane lakho eliluthelekisayo kwimveliso yebhetri. Ngokugxila kwethu okungapheliyo kuphando nophuhliso, kunye noluhlu lwethu olubanzi lweempahla zebhetri, sinikezela ngezisombululo ezimiselweyo zokumisa ukuhlangabezana neemfuno zeshishini. Ukuzibophelela kwethu ekugqwesiseni, ukulungelelaniswa kwezisombululo, kwaye ubudlelwane bobuqili bobuqili kusenza ukuba sikhe sikhetha abavelisi bepakethi yebhetri.
