Isingeniso:
Ukutshala imali kuamabhethri e-lithiumngoba uhlelo lwakho lwamandla lungaba nzima ngoba kunezincazelo eziningi ongaziqhathanisa, njengamahora e-ampere, i-voltage, impilo yomjikelezo, ukusebenza kahle kwebhethri, kanye nomthamo wokugcina ibhethri. Ukwazi umthamo wokugcina ibhethri kubalulekile ngoba kuthinta kakhulu impilo yesevisi yebhethri futhi kudlala indima ebalulekile endleleni ibhethri elisebenza ngayo ngaphansi komthwalo oqhubekayo.
Ngokuvamile, umthamo wokugcina webhethri le-lithium ubhekisela ekutheni ibhethri eligcwele ngokugcwele lingasebenza isikhathi esingakanani ngaphandle kokuthi i-voltage yehle ngaphansi kwe-voltage ethile. Lokhu kubaluleke kakhulu ukuqonda uma udinga ibhethri isikhathi eside semithwalo eqhubekayo, kunokuba kube ukuqhuma okufushane.
Uyini umthamo wokugcinwa kwebhethri?
Umthamo wokugcina, ovame ukubizwa ngokuthi i-RC, ubhekisela esikhathini (ngemizuzu) ibhethri le-12V elingasebenza ngaso ngaphambi kokuba i-voltage yehle iye ku-10.5V. Ilinganiswa ngemizuzu yokugcina. Isibonelo, uma ibhethri linomthamo wokugcina ongu-150, kusho ukuthi linganikeza ama-amps angu-25 imizuzu engu-150 ngaphambi kokuba i-voltage yehle iye ku-10.5V.
Umthamo wokugcina uhlukile kuma-amp-hours (Ah), ngoba umthamo wokugcina umane nje uyisilinganiso sesikhathi, kuyilapho amahora e-amp elinganisa inani lama-amps noma amandla kagesi angakhiqizwa ngehora elilodwa. Ungabala umthamo wokugcina usebenzisa ama-amp-hours kanye nokuphikisana nalokho, njengoba ehlobene kodwa akufani. Uma uqhathanisa lokhu okubili, umthamo we-RC uyisilinganiso esinembile sokuthi ibhethri lingasetshenziswa isikhathi esingakanani ngaphansi komthwalo oqhubekayo kunamahora e-amp.
Kungani umthamo wokugcina ibhethri ubalulekile?
Umthamo wokugcina uhloselwe ukusho ukuthi isikhathi esingakananiibhethri le-lithiumingahlala ngaphansi kwezimo zomthwalo eziqhubekayo. Kubalulekile ukwazi ukuthi ukulungele yini ukukhipha isikhathi eside, okuyisibonakaliso esihle sokusebenza kwebhethri. Uma wazi umthamo wokubeka, unombono ongcono wokuthi ungalisebenzisa isikhathi esingakanani ibhethri nokuthi ungalisebenzisa amandla angakanani. Ukuthi unemizuzu eyi-150 noma imizuzu engama-240 yomthamo wokubeka kwenza umehluko omkhulu futhi kungashintsha ngokuphelele indlela osebenzisa ngayo amabhethri akho nokuthi mangaki amabhethri ongawadinga. Isibonelo, uma udoba emanzini usuku lonke, kufanele wazi izinga lokushaja kwebhethri nesikhathi sokulisebenzisa ukuze ukwazi ukuhlela uhambo lwakho ngempumelelo futhi ufike ekhaya ngaphandle kokuphelelwa yibhethri.
Umthamo wokugcina uthinta ngqo inani lamandla ongawakhiqiza usebenzisa ibhethri. Njengoba amandla elingana nama-amps aphindaphinda ama-volts, umaibhethri le-lithiumUma i-voltage yehla kusuka ku-12V kuya ku-10.5V, amandla azoncipha. Ngaphezu kwalokho, njengoba amandla elingana nesikhathi samandla ubude bokusetshenziswa, uma amandla ehla, amandla akhiqizwayo nawo azoncipha. Kuye ngokuthi uhlela ukusebenzisa kanjani ibhethri, njengohambo lwe-RV lwezinsuku eziningi noma inqola yegalofu yokusetshenziswa ngezikhathi ezithile, uzoba nezidingo ezahlukene zamandla okugcina.
Uyini umehluko phakathi kwamandla okugcina amabhethri e-lithium namabhethri e-lead-acid?
Okokuqala, yize amabhethri e-lithium enomthamo wokugcina, akuvamile ukukalwa noma ukukhulunywa ngawo ngale ndlela, njengoba amahora e-ampere noma amahora e-watt kuyizilinganiso ezivame kakhulu zamabhethri e-lithium. Noma kunjalo, umthamo ojwayelekile wokugcina wamabhethri e-lead-acid uphansi kunowamabhethri e-lithium. Lokhu kungenxa yokuthi umthamo wokugcina wamabhethri e-lead-acid uyancipha njengoba izinga lokukhishwa lincipha.
Ngokukhethekile, isilinganiso somthamo wokugcina webhethri le-lead-acid elingu-12V 100Ah singamaminithi angu-170 - 190, kuyilapho isilinganiso somthamo wokugcina webhethri elingu-12V 100Ah.ibhethri le-lithiumcishe imizuzu engama-240. Amabhethri e-lithium anikeza amandla aphezulu okugcina ngesilinganiso esifanayo se-Ah, ngakho-ke ungonga isikhala nesisindo ngokufaka amabhethri e-lithium esikhundleni samabhethri e-lead-acid.
Isiphetho
Uma kuqhathaniswa namabhethri e-lead-acid, amabhethri e-lithium anempilo ende yesevisi, ukuminyana kwamandla okuphezulu, izidingo zokugcinwa eziphansi kanye nokusebenza okungcono kokushaja nokukhipha ishaja. Nakuba izindleko zokuqala ziphakeme, izinzuzo zawo zomnotho zesikhathi eside, ukuvikelwa kwemvelo kanye nokusebenza kahle okuphezulu kuzenza zibe ukukhetha kokuqala kobuchwepheshe bebhethri besimanje.
Uma ucabanga ukufaka ibhethri lakho le-forklift esikhundleni sebhethri le-lithium, noma ufuna ibhethri le-lithium elihlala isikhathi eside futhi elingenalo ukulungiswa kwenqola yakho yegalofu, khona-ke ungafunda ngamabhethri e-lithium e-Heltec. Sihlala sicwaninga ngemboni yamabhethri futhi sinikeza amakhasimende amabhethri e-lithium ahlukahlukene angenziwa ngezifiso ukuze ahlangabezane nezidingo zemoto yakho.Vakashela iwebhusayithi yethu ukuze ubheke!
