Isingeniso
Amabhethri e-lithiumbaye benza izinguquko ezimotweni zikagesi, kuhlanganise nezinqola zegalofu. Amabhethri e-lithium abe yinketho yokuqala ezinqoleni zegalofu zikagesi ngenxa yokuminyana kwazo okuphezulu nempilo ende. Kodwa inqola yegalofu ye-lithium-ion ingahamba ibanga elingakanani ngokushajwa okukodwa? Ake simbe emininingwaneni futhi sihlole izici ezinquma ububanzi bekalishi yegalofu elisebenza ngebhethri ye-lithium.
Uhla lokuhamba lwekalishi yegalofu yebhethri ye-lithium luncike kakhulu kumthamo webhethri, ukusebenza kahle kwenjini, indawo kanye nemikhuba yokushayela yomsebenzisi. Ngokuvamile, iphakethe lebhethri le-lithium elijwayelekile elingu-48-volt elivame ukusetshenziswa ezinqoleni zegalofu lingahamba amamayela angu-25 ukuya kwangu-35 ngokushajwa okukodwa. Nokho, lobu bubanzi bungase buhluke kuye ngezici ezihlukahlukene.
Izici ezinomthelela
Umthamo webhethri ye-lithium iyisici esibalulekile ekunqumeni ububanzi bekalishi yegalofu. Amabhethri anamandla aphezulu, afana no-200Ah noma 300Ah, angagcina amandla engeziwe futhi anikeze ibanga elide lokushayela. Ukuze ulinganisele ibanga lenqola yegalofu enebhethri ye-lithium, ungasebenzisa le fomula elandelayo:
Umthamo webhethri (Ah) x ugesi webhethri (V) x ukusetshenziswa kwamandla (Wh/mile) = ububanzi (amamayela).
Ukwengeza, ukusebenza kahle kwenjini kanye nohlelo lokuphatha amandla lulonke nakho kudlala indima ebalulekile ekwandiseni ububanzi bekalishi lakho legalofu.
Esinye sezici izinga lokushisa, njengoba amabhethri e-lithium enza kahle kakhulu phakathi kwezinga lokushisa elithile elingu-20-25 °C. Ukushisa okudlulele noma ukubanda kunganciphisa kakhulu umthamo nempilo yokuphila kwalawa mabhethri, kuthinte ukusebenza kukonke kwekalishi lakho legalofu.
Indawo ehanjwa yinqola yegalofu nayo ithinta uhla lwayo. Inqola yegalofu ingafinyelela ububanzi bayo obukhulu ezindaweni eziyisicaba nezibushelelezi, kuyilapho indawo enamagquma noma emangelengele inganciphisa ngokuphawulekayo ibanga engalihamba ngokushajwa okukodwa. Ukushayela ukhuphuke umqansi kudinga amandla engeziwe, kunciphisa ububanzi bekalishi yegalofu.
Ngaphezu kwalokho, imikhuba yokushayela yomsebenzisi izophinde ithinte imayela lenqola yegalofu. Ukusheshisa kakhulu, ukubhuleka njalo, nokushayela ngesivinini esiphezulu kuqeda ibhethri ngokushesha, okuholela ekwehleni kwebanga lokushayela. Ukugibela okushelelayo, ngakolunye uhlangothi, kuthuthukisa ukusetshenziswa kwebhethri futhi kunwebe ibanga lekalishi lakho legalofu.
Ukuze ukwandise ibanga lokushayela lekalishi lakho le-lithium yebhethri yegalofu, kubalulekile ukuqinisekisa ukuthi ibhethri inakekelwa kahle. Ukushaja njalo, ukugwema ukuchithwa okujulile, nokugcina ibhethri lakho likuzinga lokushisa elilungile kungasiza ukunweba impilo yalo nokugcina ukusebenza kahle kwalo, okusiza ekugcineni ukunweba ibanga lakho lokushayela.
Intuthuko kubuchwepheshe bebhethri ye-lithium nayo iyasiza ekuthuthukiseni ububanzi bezinqola zegalofu zikagesi. Abakhiqizi bayaqhubeka nokusungula futhi bathuthukise amabhethri e-lithium anokuminyana kwamandla aphezulu nokusebenza kahle okwengeziwe, okusho ngokuqondile ukukhushulwa kwemayela ezinqoleni zegalofu.
Ukwengeza, ukuhlanganiswa kwesistimu yokuphatha ibhethri ehlakaniphile kanye nobuchwepheshe bokubhuleka okuvuselelayo kukhulisa ukusebenza kahle kukonke kwekalishi legalofu i-lithium-ion, okulivumela ukuthi lihambe amabanga amade ngeshaji eyodwa.
Isiphetho
Kafushane, ububanzi bekalishi yegalofu yebhethri ye-lithium buzohluka ngokuya kumthamo webhethri, ukusebenza kahle kwemoto, indawo kanye nemikhuba yokushayela yomsebenzisi. Ngokuthuthuka kobuchwepheshe bebhethri ye-lithium kanye nokwenza ngcono okuqhubekayo komklamo wemoto kagesi, uhla lwezinqola zegalofu zebhethri ye-lithium kulindeleke ukuthi luphinde lwande ngokuzayo, lunikeze abadlali begalofu indlela yokuhamba enokwethenjelwa nesebenza kahle kakhulu esifundweni.
Kubalulekile ukukhetha umphakeli nesifaki othembekile futhi ulandele imihlahlandlela yomkhiqizi yokunakekelwa nokunakekelwa ukuze uqinisekise ukusebenza okuphelele kanye nempilo ende yebhethri ye-lithium. I-Heltec Energy ingumphakeli wakho omethembayo, Sihlala sithuthukisa futhi sakha izinto ezintsha embonini yebhethri ye-lithium, kuphela ukukunikeza ngamabhethri e-lithium asezingeni eliphezulu nezinsizakalo ezenziwe ngokwezifiso ezihlangabezana nezidingo zakho.
Uma unemibuzo noma ungathanda ukufunda okwengeziwe, sicela ungangabazifinyelela kithi.
