Isingeniso：
Amabhethri e-lithium akhona yonke indawo ezimpilweni zethu. Amabhethri ethu efoni ephathekayo kanye namabhethri emoto kagesi konke kuyatholakalaamabhethri e-lithium, kodwa uyazi yini amagama ayisisekelo ebhethri, izinhlobo zebhethri, kanye nendima nomehluko wochungechunge lwebhethri kanye nokuxhumeka okuhambisanayo? Ake sihlole ulwazi lwamabhethri ngeHeltec.
Amagama ayisisekelo amabhethri e-lithium
1) Izinga le-C
Kubhekisele esilinganisweni samandla kagesi namandla ajwayelekile ebhethri le-lithium ngesikhathi sokushaja nokukhipha ibhethri. Kuchaza ukuthi ibhethri lingashajwa futhi likhishwe ngokushesha kangakanani. Amazinga okushaja nokukhipha ibhethri awafani ngempela. Isibonelo:
1C: khipha ibhethri ngokuphelele zingakapheli ihora eli-1 (ukushaja okugcwele)
0.2C: khipha ibhethri ngokuphelele zingakapheli amahora ama-5 (ukushaja okugcwele)
5C: khipha ibhethri ngokuphelele zingakapheli amahora angu-0.2 (ukushaja okugcwele)
2) Umthamo
Inani likagesi eligcinwe ku-ibhethri le-lithiumIyunithi iyi-mAh noma i-Ah.
Uma kuhlanganiswa nesilinganiso, isibonelo, uma ibhethri lingu-4800mAh futhi izinga lokushaja lingu-0.2C, kusho ukuthi kuthatha amahora ama-5 ukuthi ibhethri lishajwe ngokugcwele kusukela lingenalutho (ukunganaki isigaba sokushaja ngaphambi kwesikhathi lapho ibhethri liphansi kakhulu).
Amandla okushaja angu: 4800mA*0.2C=0.96A
3) Uhlelo lokuphatha ibhethri le-BMS
Uhlelo lulawula futhi luphatha ukushaja/ukukhipha ibhethri, luthola izinga lokushisa kanye ne-voltage yebhethri, luxhumane nohlelo lwe-host, lulinganisela i-voltage yebhethri, futhi luphatha ukusebenza kokuphepha kwephakethe lebhethri le-lithium.
4) Umjikelezo
Inqubo yokushaja nokukhipha ibhethri ibizwa ngokuthi umjikelezo. Uma ibhethri lisebenzisa kuphela u-80% wamandla alo aphelele isikhathi ngasinye, impilo yomjikelezo wamabhethri e-lithium-ion ingaba phezulu izikhathi eziyizinkulungwane.
Uhlobo lwebhethri le-Lithium
Njengamanje, amaseli e-lithium-ion ezentengiselwano ikakhulukazi ayindilinga, ayizikwele futhi athambile.
Amaseli ayi-cylindrical angu-18650 angamaseli e-lithium-ion anomthamo omkhulu wokukhiqiza okwamanje. Amaseli ethu ebhethri okuqapha uchungechunge lwe-G angalolu hlobo.
Uchungechunge lweseli kanye nokuxhumeka okuhambisanayo
Iseli liyingxenye eyinhloko ye-ibhethri le-lithiumInani lamaseli liyahlukahluka kuye ngokusetshenziswa kwebhethri, kodwa wonke amabhethri adinga ukuxhunywa ngezindlela ezahlukene ukuze kufezwe i-voltage namandla adingekayo.
Qaphela: Izimo zokuxhumeka okuhambisanayo zinzima kakhulu. Ngakho-ke, ukuxhumana okuhambisanayo kuqala bese kuba ukuxhumana okulandelanayo kunganciphisa izidingo zokuqina kwebhethri.
U: Uyini umehluko phakathi kwamabhethri anezinhla ezintathu kanye namane ahambisanayo kanye namane ahambisanayo kanye namane ahambisanayo kanye namane ahambisanayo?
A: I-voltage kanye nomthamo kuhlukile.Ukuxhumeka kochungechunge kwandisa i-voltage, kanti ukuxhumana okuhambisanayo kwandisa amandla kagesi (umthamo)
1) Ukuxhumana okuhambisanayo
Ake sithi i-voltage yeseli yebhethri ingu-3.7V kanti umthamo wayo ungu-2.4Ah. Ngemva kokuxhumeka okuhambisanayo, i-voltage yokugcina yesistimu isengu-3.7V, kodwa umthamo wayo uyanda uye ku-7.2Ah.
2) Uxhumano lochungechunge
Ake sithi i-voltage yeseli yebhethri ingu-3.7V kanti umthamo wayo ungu-2.4Ah. Ngemva kokuxhumeka ochungechungeni, i-voltage yokugcina yesistimu ingu-11.1V, futhi umthamo wayo awushintshi.
Uma iseli lebhethri liyichungechunge ezintathu kanye namabili ahambisanayo, inani lamaseli ayi-6 18650, khona-ke ibhethri lingu-11.1V kanye no-4.8Ah. I-Tesla Model-S sedan isebenzisa amaseli e-Panasonic 18650, kanti iphakethe lebhethri elingu-85kWh lidinga amaseli angaba ngu-7,000.
Isiphetho
I-Heltec izoqhubeka nokuvuselela ulwazi lwesayensi oludumile mayelanaamabhethri e-lithiumUma unesithakazelo, ungakunaka. Ngesikhathi esifanayo, sikunikeza amabhethri e-lithium asezingeni eliphezulu ukuze uwathenge futhi sinikeze izinsizakalo ezenziwe ngokwezifiso ukuze zihlangabezane nezidingo zakho.
I-Heltec Energy ingumlingani wakho othembekile ekukhiqizeni amaphakethe ebhethri. Ngokugxila kwethu ocwaningweni nasekuthuthukisweni okungapheli, kanye nohlu lwethu oluphelele lwezesekeli zebhethri, sinikeza izixazululo ezifika kanye ukuze kuhlangatshezwane nezidingo ezishintshayo zomkhakha. Ukuzibophezela kwethu ekwenzeni kahle, izixazululo ezenzelwe wena, kanye nokubambisana okuqinile kwamakhasimende kusenza sibe yisinqumo esikhethwa kakhulu ngabakhiqizi nabahlinzeki bamaphakethe ebhethri emhlabeni jikelele.
Uma unemibuzo noma ungathanda ukwazi okwengeziwe, sicela ungangabazi ukungithumelelaxhumana nathi.
