Isingeniso:
Ukutshala imali kuamabhethri e-lithiumngohlelo lwakho lwamandla kungase kube nzima ngoba kunemininingwane eminingi ongayiqhathanisa, njengamahora ama-ampere, i-voltage, impilo yomjikelezo, ukusebenza kahle kwebhethri, namandla okugodla ibhethri. Ukwazi umthamo webhethri kubalulekile ngoba kuthinta kakhulu impilo yesevisi yebhethri futhi kudlala indima ebalulekile endleleni ibhethri elisebenza ngayo ngaphansi komthwalo oqhubekayo.
Ngokuvamile, umthamo wokugodla webhethri ye-lithium ubhekisela ekutheni ibhethri elishajwe ngokugcwele lingasebenza isikhathi esingakanani ngaphandle kokuthi i-voltage yehle ngaphansi kwe-voltage ethile. Lokhu kubaluleke kakhulu ukukuqonda uma udinga ibhethri isikhathi eside sokulayisha okuqhubekayo, kunokuqhuma okufushane.
Yini umthamo wokugcinwa kwebhethri?
Umthamo wokulondoloza, ovame ukubizwa ngokuthi i-RC, ubhekisela esikhathini (ngemizuzu) ibhethri engu-12V engasebenza ngaphambi kokuba i-voltage yehle ibe ngu-10.5V. Kukalwa ngamaminithi abekiwe. Isibonelo, uma ibhethri linomthamo wokugodla ongu-150, kusho ukuthi linganikeza ama-amps angu-25 imizuzu engu-150 ngaphambi kokuba i-voltage yehle ibe ngu-10.5V.
Umthamo wokulondoloza uhlukile kuma-amp-amahora (Ah), kulowo mthamo wokugodla umane uyisilinganiso sesikhathi, kuyilapho ama-amp-amahora ekala inani lama-amps noma lamanje elingakhiqizwa ngehora elilodwa. Ungakwazi ukubala umthamo wokugodla usebenzisa ama-am-awa futhi ngokuphambene nalokho, njengoba ahlobene kodwa awafani. Uma uqhathanisa kokubili, umthamo we-RC uyisilinganiso esinembe kakhudlwana sokuthi ibhethri lingasetshenziswa isikhathi esingakanani ngaphansi komthwalo oqhubekayo kunamahora ama-amp.
Kungani umthamo webhethri ubalulekile?
Umthamo wokulondoloza uhloselwe ukutshela ukuthi isikhathi esingakanani aibhethri ye-lithiumingahlala ngaphansi kwezimo eziqhubekayo zokulayisha. Kubalulekile ukwazi ukuthi ukulungele yini ukukhipha isikhathi eside, okuyinkomba enhle yokusebenza kwebhethri. Uma uwazi umthamo wokugodla, unombono ongcono wokuthi ungasebenzisa isikhathi esingakanani ibhethri nokuthi mangakanani amandla ongawasebenzisa. Ukuthi unemizuzu engu-150 noma imizuzu engu-240 yomthamo wokugodla kwenza umehluko omkhulu futhi kungashintsha ngokuphelele indlela osebenzisa ngayo amabhethri akho nokuthi mangaki amabhethri ongawadinga. Isibonelo, uma uphumile uyodoba emanzini usuku lonke, kufanele wazi izinga lokushajwa kwebhethri nesikhathi sokusebenzisa ukuze ukwazi ukuhlela uhambo lwakho ngempumelelo futhi ubuyele ekhaya ngaphandle kokuphelelwa ibhethri.
Umthamo wokugcina uthinta ngqo inani lamandla ongawakhiqiza usebenzisa ibhethri. Njengoba amandla alingana nama-amps izikhathi volts, uma iibhethri ye-lithiumI-voltage yehla isuka ku-12V iye ku-10.5V, amandla azokwehla. Ngaphezu kwalokho, njengoba amandla alingana nezikhathi zamandla ubude bokusetshenziswa, uma amandla ehla, amandla akhiqizwayo nawo azokwehla. Kuya ngokuthi uhlela ukulisebenzisa kanjani ibhethri, njengohambo lwe-RV lwezinsuku eziningi noma inqola yegalofu ukuze uyisebenzise ngezikhathi ezithile, uzoba nezidingo zomthamo ohlukile wokugodla.
Uyini umehluko phakathi komthamo obekiwe wamabhethri e-lithium namabhethri e-lead-asidi?
Okokuqala, ngenkathi amabhethri e-lithium enawo amandla okugodla, awavamisile ukukalwa noma ukushiwo ngale ndlela, njengoba amahora ama-ampere noma amahora we-watt kuyizilinganiso ezivame kakhulu zamabhethri e-lithium. Noma kunjalo, umthamo wokugcinwa omaphakathi wamabhethri e-lead-asidi uphansi kunalowo wamabhethri e-lithium. Lokhu kungenxa yokuthi amandla okugodla amabhethri e-lead-acid ayehla njengoba izinga lokuphuma lincipha.
Ngokukhethekile, umthamo wokugodla omaphakathi webhethri le-lead-acid engu-12V 100Ah cishe imizuzu eyi-170 - 190, kuyilapho umthamo wokugodla omaphakathi we-12V 100Ah.ibhethri ye-lithiumcishe imizuzu engama-240. Amabhethri e-lithium anikezela ngomthamo wokugcina wokugcina esilinganisweni sika-Ah esifanayo, ukuze ukwazi ukonga 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 aphezulu, izimfuneko eziphansi zokunakekelwa kanye nokusebenza okungcono kokushaja nokukhipha. Nakuba izindleko zokuqala ziphezulu, izinzuzo zabo zezomnotho zesikhathi eside, ukuvikelwa kwemvelo nokusebenza kahle okuphezulu kubenza babe ukukhetha kokuqala kobuchwepheshe besimanje bebhethri.
Uma ucabanga ukushintsha ibhethri lakho le-forklift ngebhethri ye-lithium, noma ufuna ibhethri le-lithium elinempilo yebhethri ende futhi akukho ukunakekelwa kwekalishi lakho legalofu, ungafunda ngamabhethri e-lithium akwa-Heltec. Sihlala sicwaninga imboni yebhethri futhi sihlinzeka amakhasimende ngezinhlobonhlobo zamabhethri e-lithium angenziwa ngokwezifiso ukuze ahlangabezane nezidingo zemoto yakho.Vakashela iwebhusayithi yethu ukuze ubuke!
