Yintoni isilawuli ibhetri. Intlawulo isilawuli Li-Ion-ibhetri

Nabaqondisi ngokwabo izixhobo luncedo. Kwaye ukuze siqonde ngcono le topic, kufuneka asebenze kunye umzekelo ethile. Ngoko ke, siqwalasela umlawuli ophetheyo bebhetri. Yintoni na? wenza njani? Yintoni umsebenzi apho?

Yintoni na umlawuli ophetheyo

Usebenzela esweni ekunciphiseni Ilahleko ye-eneji kunye nenkcitho. Okokuqala, oko ophetheyo wokubeka iliso ukuguquka amandla ombane abe ngamandla imichiza, ukuya khona kwakho imfuneko olathi iisekethe ubonelelo okanye izixhobo ezifunekayo. Yenza umlawuli ophetheyo ngezandla zakho ayikho nzima. Kodwa kwakhona kuthathwa umbane, izinto ezo ezingafanelekileyo umyalelo.

wenza indlela esisebenza

Kakade ke, eli cebo jikelele ayikho. Kodwa abaninzi kumsebenzi wabo usebenzisa ezimbini resistor posdtroechnyh elawula umda ombane eliphezulu nengasezantsi. Xa iya ngaphaya kwemida ubalula, unxibelelwano iqala jiko relay kwaye luvuliwe. Nangona isebenza, le ombane lihla ngaphantsi, kwinqanaba elithile pre-uzimisele enyanisweni. Apha kuyimfuneko ukuthetha malunga nento yokuba kukho iindlela ezininzi ezahlukeneyo. Ngoko ke, lo ibhetri ingafakwa abathathu, zantlanu elinababini, kunye volts elinesihlanu. Enyanisweni, yonke into ixhomekeke ukuphunyezwa zekhompyutha le. Makhe sijonge indlela umlawuli ophetheyo kwiimeko ezahlukeneyo.

Zeziphi ezi ntlobo

Kufuneka kuqatshelwe Iyantlukwano enkulu, nto leyo ndiqhayise umlawuli ophetheyo. Xa sincokola ngayo iimbono zabo, masenze kucalulo ngokuxhomekeke umda lwesicelo:

1. Kuba eneji ehlaziyekayo.
2. Kuba zasendlini.
3. For mobile.

Kakade ke, iintlobo ngokwabo kakhulu ngakumbi. Kodwa ke, njengoko sicinga umlawuli ophetheyo ukusuka kwindawo jikelele lwembono, oko kwanele kuthi nabo. Ukuba sithethe ngabo zisetyenziselwa iiphaneli zesola kunye turbines umoya, apho umda ombane eliphezulu kudla ulingana volts-15, lo gama i ephantsi - 12 B. Ibhetri esiyidalayo unikezelo eqhelekileyo 12 V amandla elidityaniswe kuyo entle edluliselwe contact ezivaliweyo. Kwenzeka ntoni xa ombane ibhetri idlula 15 V? Kwiimeko ezinjalo, eli ikhutshwa phandle irileyi wesekethe. Ngenxa yoko, umthombo wamandla ibhetri watshintshela nomthwalo zokulinganisa. Kufuneka kuqatshelwe ukuba ayikho ngokukodwa ukuba kwazeke iiphaneli zesola, ngenxa yeziphumo ebezingalindelekanga ethile. Kodwa umbane umoya , ukuba kunyanzelekile. izixhobo zombane zasekhaya izixhobo ngeselula neempawu zabo. Enanikade cwecwe isilawuli ibhetri, uchukumise into iqhosha cell phones twatse.

Khangela kulo lwe Lithium-ion cell phone

Ukuba ukhetha ukuvula nayiphi na ibhetri, uyaqaphela ukuba encinane soldered ukuya iterminal iseli kwibhodi wesekethe. Libizwa ngokuba isekethe yokhuseleko. Isibakala sokuba neebhetri lwe Lithium-ion zifuna esweni rhoqo. isilawuli ithi ibhodi yesekethe elincinane apho yesekethe olusekelwe eyenziwe SMD-amacandelo. Yena, ke, yahlulwe iitshiphusi ezimbini - enye yazo ibe kolawulo, enye - yesigqeba. Masithethe ngakumbi malunga yesibini.

scheme executive

Oku kusekelwe transistors MOSFET. Ngokuqhelekileyo, kukho izinto ezimbini. Nj efanayo kakhulu babe 6 okanye 8 izikhonkwane. Ukulawula intlawulo eyahlukileyo nokuchithela iseli ibhetri usebenzisa transistors ezimbini intsimi-isiphumo ukuba izindlu efanayo. Ngoko ke, umntu ukuqhagamshela okanye uyeke umthwalo. A transistor yesibini benze into enye, kodwa umbane (apho isebenza kwitshaja). Ngenxa yokuphunyezwa kwe icebo olunjalo kuchaphazela ubomi bebhetri ngaphandle iingxaki. Ukuba oyifunayo, inokusetyenziswa kwenye indawo. Kodwa ke kufuneka kukhunjulwe ukuba eli yesekethe isigxina ibhetri kwaye ke zinokusetyenziswa kuphela kwezixhobo nezinto ezithe uluhlu elilinganiselweyo msebenzi. Ukuze ufumane iinkcukacha ezingaphezulu ngezi mpawu, siya ngoku ukuxoxa.

Ukhuseleko ngokuchasene ukutshaja ixesha elide kungabenza

Inyaniso yeyokuba xa ombane kwebhetri Lithium kune 4.2, inokuba shushu ngokugqithisileyo kwaye zisenokuqhushumba. Kuba oku afana elements chips ezinjalo, nto leyo eza kuyeka xa isigxina isalathisi. Kwaye ngokuqhelekileyo, de ombane ufikelela ithagethi ka 4-4,1 V ukusuka ukusetyenziswa okanye inkqubo self-ukubhobhoza, Ukuvuya womserbia ngakumbi akwenzeki. Lo msebenzi obalulekileyo yabelwa intlawulo isilawuli ibhetri Lithium.

Ukhuseleko ngokuchasene kwentengo

Xa ombane lifikelela amaxabiso ebalulekileyo ephantsi ezenza ukusebenza yingxaki efanayo yecebo elizibonakalisa ngokwalo (ngokwesiqhelo kwi 2,3-2,5V kuluhlu), ngoko sivala ehambelana MOSFET-transistor, nenoxanduva unikezelo lwangoku lwe iselula. Okulandelayo kukho inguqulelo ukulala imo ngesifo ngamandla encinci. Kwaye ke kukho ngumba umdla kakhulu lo msebenzi. Ngoko ke, lo gama i-ombane iseli ibhetri mkhulu 2.9-3.1 V, isixhobo mobile baza kuba nako ukusebenza eqhelekileyo. Mhlawumbi Ungase uphawule kukuba xa wokufaka ifowuni, libonisa ukuba kukho intlawulo, kodwa ke ethubeni yaye asebenza ziqhele akafuni.

iindlela zokukhusela

Kufuneka kuqatshelwe ukuba umlawuli ophetheyo eziliqela izinto ekufuneka ukukhusela ngokuchasene neziphumo ezibi. Ngoko ke, lo ode olwaye lwamfimfitha zicwangciswe kwi transistors endle-isiphumo, wesiphaluka isigxina ucupho kunye ezongeziweyo ezimbalwa. Ewe, kwaye ukuba ungakwazi ukukhangela ibhetri isigxina isilawuli kwaye bafunde umsebenzi wamandla umthombo, umsebenzi yayo kubuyiselwa nokuba i "ukufa". Kakade ke, oku kuthetha ukuba kumiwe yomsebenzi, hayi uqhushumbo okanye isikhungo. Kulo mzekelo, inokunceda izixhobo ezikhethekileyo ukuba enze ekhethekileyo "wobuyiselo" isigxina. Kakade ke, baya kusebenza ixesha elide - inkqubo Ungatsala kwi for inqwaba iiyure, kodwa ibhetri emva kokugqitywa ngempumelelo umsebenzi uya kuba phantse zintsha.

isiphelo

Njengoko ubona, intlawulo isilawuli Li-Ion-ibhetri ludlala indima ebalulekileyo ekuqinisekiseni ukuba ixesha komsebenzi iifowuni kunye nempembelelo entle ebomini babo. Ngenxa elula wokwenziwa kwawo inokufunyanwa phantse ucingo okanye tablet. Ukuba kukho umnqweno ukubona ngamehlo nezandla zakhe ukuba bachukumise intlawulo isilawuli Li-Ion-ibhetri kunye nemixholo yawo, ngoko uluhlu lomshiceleliQXml kufuneka kukhunjulwe ukuba umsebenzi wenziwe kunye elementomv imichiza, ngoko yiba nononophelo ethile.
