Iibhetri zeLithium zifuna ukukhuselwa.Ukuba i18650 lithium ibhetriayinayo ibhodi yokukhusela, okokuqala, awuyazi ukuba ibhetri ye-lithium ihlawuliswa kangakanani, kwaye okwesibini, ayinakuhlawuliswa ngaphandle kwebhodi yokukhusela, kuba ibhodi yokukhusela kufuneka idibaniswe nebhetri ye-lithium kunye neengcingo ezimbini.Musa ukucinga ukuba umgangatho webhetri ye-lithium oyithengileyo ulungile ngaphandle kwebhodi yokukhusela, kodwa ukuba kuthatha ixesha elide, iingxaki ezahlukeneyo ziya kwenzeka.
Xa ihlawulwe ngokupheleleyo, ibhodi yokukhusela ibhetri ye-lithium kukutshaja kunye nokukhupha ukhuseleko lwe-series ye-lithium ibhetri yepakethe, enokuqinisekisa ukuba umehluko we-voltage phakathi kweebhetri ungaphantsi kwexabiso elimiselweyo, kwaye unokufezekisa ibhalansi yebhetri nganye kwibhetri. ipakethe, ngaloo ndlela iphucula ngempumelelo udibaniso lonxibelelwano Isiphumo sokutshaja kwindlela yokutshaja.Kwangaxeshanye, inokubona i-overvoltage, i-overcharge, i-overdischarge, isiphaluka esifutshane kunye nokufudumeza kwebhetri eveliswa yi-welder nganye ye-lithium yebhetri kwi-pack yebhetri ukukhusela kunye nokwandisa ubomi bebhetri.Ukukhuselwa ngaphantsi kwe-voltage kunokuthintela iseli nganye ukuba yonakaliswe ngokukhupha ngokugqithisileyo ngexesha lokukhutshwa.
1. Ukukhetha ibhodi yoKhuseleko kunye nokubiza kunye nokukhupha imicimbi yokusetyenziswa
(Idatha yeyelithium iron phosphate ibhetri, umgaqo webhetri ye-3.7v eqhelekileyo iyafana, kodwa idatha yahlukile)
Injongo yebhodi yokukhusela kukukhusela ibhetri ekugqithiseni kunye nokukhupha ngokugqithiseleyo, ukuthintela umbane ophezulu ekonakalisweni kwebhetri, kunye nokulinganisela umbane webhetri xa uhlawulwe ngokupheleleyo (ubuchule bokulinganisa ngokuqhelekileyo buncinci, ngoko ke ukuba kukho ibhodi yokukhusela ibhetri yokuzikhupha, kakhulu Kunzima ukulungelelanisa, kwaye kukho neebhodi zokukhusela ezilungelelanisayo nakweyiphi na imeko, oko kukuthi, ibhalansi yenziwa ukususela ekuqaleni kokutshaja, okubonakala kunqabile).
Kubomi bepakethi yebhetri, kucetyiswa ukuba i-voltage yokutshaja ibhetri ingadluli kwi-3.6v nangaliphi na ixesha, oku kuthetha ukuba i-voltage yesenzo sokukhusela ibhodi yokukhusela ayikho ngaphezu kwe-3.6v, kwaye i-voltage elinganisiweyo iyacetyiswa ukuba ibe I-3.4v-3.5v (iseli nganye i-3.4v ihlawuliswe ngaphezu kwe-99% Ibhetri, ibhekisela kwi-static state, i-voltage iya kwanda xa ihlawulisa ngokuphezulu kwangoku).I-voltage yokukhusela ukukhutshwa kwebhetri ngokuqhelekileyo ingaphezulu kwe-2.5v (ngaphezulu kwe-2v akuyona ingxaki enkulu, ngokuqhelekileyo kukho ithuba lokusebenzisa ngokupheleleyo ngaphandle kwamandla, ngoko ke le mfuneko ayikho phezulu).
2. I-voltage ephezulu ephakanyisiweyo yeshaja (isinyathelo sokugqibela sokutshaja sinokuba yimowudi ephezulu yokutshaja i-voltage rhoqo) ngu-3.5 * inani leentambo, ezifana malunga ne-56v kwiintambo ze-16.Ngokuqhelekileyo ukutshaja kunokunqunyulwa kwi-avareji ye-3.4v kwiseli nganye (ngokusisiseko ngokupheleleyo), ukwenzela ukuba ubomi bebhetri buqinisekisiwe, kodwa ngenxa yokuba ibhodi yokukhusela ingakaqalisi ukulinganisela, ukuba i-core yebhetri ine-self-discharge enkulu. , iya kuziphatha njengeqela lonke ngexesha Umthamo uyancipha ngokuthe ngcembe.Ngoko ke, kuyimfuneko ukubiza ibhetri nganye kwi-3.5v-3.6v rhoqo (umzekelo ngeveki nganye) kwaye uyigcine iiyure ezininzi (logama nje umyinge umkhulu kunokulinganisa umbane wokuqalisa ukulinganisa), okukhulu ukuzikhupha, ixesha elide ukulinganisa kuya kuthatha, kwaye i-self-discharge Oversized cells inzima ukulinganisa kwaye ifuna ukupheliswa.Ngoko xa ukhetha ibhodi yokukhusela, zama ukukhetha ukhuseleko lwe-3.6v overvoltage, kwaye uqale ukulinganisa malunga ne-3.5v.(Uninzi lwe-overvoltage yokukhusela kwimarike ingaphezulu kwe-3.8v, kwaye i-equilibrium iqalwe ngaphezu kwe-3.6v).Ngapha koko, ukukhetha umbane olungeleleneyo wokuqala olungelelanisiweyo kubaluleke ngakumbi kunombane okhuselayo, kuba amandla ombane aphezulu anokulungelelaniswa ngokuhlengahlengisa umda wombane omkhulu wetshaja (oko kukuthi, ibhodi yokhuselo ayinalo ithuba lokwenza ukhuseleko lwamandla ombane aphezulu. ), kodwa ukuba i-voltage elinganisiweyo iphezulu, ipakethe yebhetri ayinalo ithuba lokulinganisela (ngaphandle kokuba i-voltage yokutshaja inkulu kunombane wokulinganisa, kodwa oku kuchaphazela ubomi bebhetri), iseli yebhetri iya kuncipha ngokuthe ngcembe ngenxa yokuzikhupha. umthamo (iseli efanelekileyo ene-self-discharge ye-0 ayikho).
3. Ukukhutshwa ngokuqhubekayo kwikhono langoku lebhodi yokukhusela.Le yeyona nto imbi kakhulu yokuphawula.Ngenxa yokuba amandla akhoyo okunciphisa ibhodi yokukhusela ayinantsingiselo.Umzekelo, ukuba uvumela ityhubhu ye-75nf75 iqhubeke idlula i-50a yangoku (ngeli xesha, amandla okufudumeza malunga ne-30w, ubuncinane ama-60w amabini kwi-series kwibhodi enye ye-port), nje ukuba kukho ubushushu bokufudumala ngokwaneleyo ukuba buchithe. ubushushu, akukho ngxaki.Inokugcinwa kwi-50a okanye ngaphezulu ngaphandle kokutshisa ityhubhu.Kodwa awukwazi ukuthetha ukuba le bhodi yokukhusela ingahlala i-50a yangoku.Kuba uninzi lweepleyiti ezikhuselayo zomntu wonke zibekwe kwibhokisi yebhetri kufutshane kakhulu nebhetri, okanye zivale.Ngoko ukushisa okuphezulu okunjalo kuya kutshisa ibhetri kwaye kushushu.Ingxaki kukuba ubushushu obuphezulu lutshaba olubulalayo lwebhetri.
Ngoko ke, indawo yokusetyenziswa kwebhodi yokukhusela inquma indlela yokukhetha umda wangoku (kungekhona umthamo wangoku webhodi yokukhusela ngokwayo).Ukuba ibhodi yokukhusela ikhutshwe kwibhokisi yebhetri, ngoko ke phantse nayiphi na ibhodi yokukhusela ene-heat sink inokusingatha i-50a ngoku eqhubekayo okanye nangaphezulu (ngeli xesha, kuphela umthamo webhodi yokukhusela uqwalaselwa, kwaye akukho mfuneko yokukhathazeka malunga nayo. ukunyuka kweqondo lobushushu kubangela umonakalo kwiiseli).Masithethe ngemekobume esetyenziswa ngumntu wonke, ekwindawo evalelweyo efanayo nebhetri.Ngeli xesha, amandla aphezulu okufudumeza kwebhodi yokukhusela alawulwa kakuhle ngaphantsi kwe-10w (ukuba ibhodi yokukhusela encinci, idinga i-5w okanye ngaphantsi, kwaye ibhodi yokukhusela ivolumu enkulu ingaba ngaphezu kwe-10w, kuba inokushisa okulungileyo. ukutshatyalaliswa kunye nobushushu abuyi kuba phezulu kakhulu).Ngokumalunga nokuba kungakanani okufanelekileyo, ngoku okuqhubekayo kunconywa Xa ubushushu obukhulu bebhodi yonke bungadluli ama-degrees angama-60 (eyona nto ingaphantsi kwama-50 degrees).Ngokwethiyori, iqondo lokushisa eliphantsi lebhodi yokukhusela, lingcono, kwaye lingaphantsi liya kuchaphazela iiseli.
4. Umahluko phakathi kwebhodi yebhodi enye kunye nebhodi yebhodi ehlukeneyo: ibhodi ye-port efanayo ngumgca ofanayo wokuhlawula kunye nokukhupha, kwaye zombini ukuhlawula kunye nokukhupha kukhuselwe.
Ibhodi ye-port eyahlukileyo izimeleyo kumgca wokutshaja kunye nomgca wokukhupha.Isango lokutshaja likhusela kuphela ekutshajisweni xa utshaja, kwaye alikhuseli ukuba likhutshiwe kwizibuko lokutshaja (kodwa lingakhupha ngokupheleleyo, kodwa umthamo wangoku wezibuko lokutshaja ngokuqhelekileyo lincinci).I-port yokukhupha ikhusela ukukhutshwa ngokugqithisileyo ngexesha lokukhutshwa.Ukuba ukutshaja kwizibuko lokukhupha, ukutshaja okungaphezulu akukhuselwanga (ngoko ke ukutshajiswa ngasemva kwe ecpu kusetyenziswa ngokupheleleyo kwibhodi yezibuko eyahlukileyo. Kwaye intlawulo ebuyayo ingaphantsi ngokupheleleyo kumandla asetyenzisiweyo, ngoko Sukuba nexhala malunga nokutshajisa kakhulu ibhetri ngenxa yokutshaja umva.
Bala ubuninzi obuqhubekayo bangoku bemoto yakho, khetha ibhetri enesakhono esifanelekileyo okanye amandla anokuthi ahlangabezane nalo mjelo uqhubekayo kunye nokunyuka kobushushu kulawulwa.Ubuncinci ukuchasana kwangaphakathi kwebhodi yokukhusela, kungcono.Ibhodi yokukhusela i-overcurrent protection eneneni ifuna kuphela ukhuseleko lwesiphaluka esifutshane kunye nolunye ukhuseleko lokusetyenziswa okungaqhelekanga.
Isishwankathelo: Ukusetyenziswa kweebhetri ze-lithium kufuneka kulawule ubushushu obuphezulu (ukunyuka kweqondo lokushisa okubangelwa ukukhutshwa okuphezulu kwangoku okanye okubangelwa yimeko engqongileyo), kunye nokulawula umbane ophezulu wokutshaja kunye nomthamo omncinci wokukhupha (ukuba ugqitywe ngebhodi yokukhusela kunye neshaja ).Kungcono ukugcina ibhetri kwi-voltage yeqonga (malunga ne-3.25-3.3v ye-lithium iron phosphate) xa ingasetyenziswa.
Ukunciphisa ukuchasana kwangaphakathi kwebhodi yokukhusela, kungcono, kwaye kuphantsi ukuchasana kwangaphakathi, ukufudumala kuncinci.Umda wangoku webhodi yokukhusela unqunywe ngokuxhatshazwa kwesampula yocingo lobhedu, kodwa ikhono eliqhubekayo langoku lichongwa yi-mos (kuba ukuchasana kwangaphakathi kwe-mos kugqiba ukunyuka kweqondo lokushisa).
