Kufuneka kuqatshelwe ekusebenziseni ibhetri ye-lithium ukuba ibhetri ifakwe kwindawo yokulala, ngelo xesha umthamo ungaphantsi kwexabiso eliqhelekileyo, ixesha lokusetyenziswa lifutshane. Nangona kunjalo, ibhetri ye-lithium kulula ukuyisebenzisa, kwaye ibhetri inokuthi isebenze ngokude nje idlula kwi-3-5 intlawulo eqhelekileyo kunye nemijikelezo yokukhupha, kwaye umthamo oqhelekileyo ubuyiselwe. Ngenxa yeempawu zebhetri ye-lithium ngokwayo, inquma ukuba akukho phantse impembelelo yememori.

Ngoko ke, ibhetri entsha ye-lithium kwifowuni yomsebenzisi ikwinkqubo yokuvula, akukho ndlela ekhethekileyo kunye nesixhobo. Ayiyothiyori kuphela ithiyori, ukusuka kokwam ukuziqhelanisa, ukusuka ekuqaleni, indlela eqhelekileyo isetyenziselwa ukuhlawulisa le ndlela "yokusebenza kwendalo" yeyona ndlela ilungileyo. Kwingxaki ye "activation" yeebhetri ze-lithium, ezininzi iinkcazo zezi: ixesha lokutshaja kufuneka libe ngaphezu kweeyure ezili-12, liphindwe kathathu ukuze kusebenze ibhetri.

Le "eyokuqala ezintathu-ezintathu itshaja iiyure ezili-12 ngaphezulu" yathi kuyacaca ukuqhubeka kwiibhetri zenickel ezifana ne-nickel-cadmium kunye ne-nickel hydrogen. Ke olu hlobo lwentetho, kunokuthiwa alugqibekanga. Iimpawu zokutshaja kunye nokukhupha iibhetri ze-lithium kunye neebhetri ze-nickel zingahluka kakhulu, kwaye unokukuxelela ngokucacileyo.

Zonke izixhobo zobugcisa ezinzulu ezisesikweni ndiziphononongile zigxininisa ukuba ziya kuhlawulisa kakhulu kwaye zikhuphe ngaphezulu kweebhetri ze-lithium, ngakumbi i-lithium engamanzi. Ibhetri ye-ion ibangela umonakalo omkhulu. Ke ngoko, ukutshaja kukhethwa ngokufanelekileyo ngokwexesha eliqhelekileyo kunye nendlela eqhelekileyo, ngakumbi ngaphezulu kweeyure ezili-12 zokutshaja ixesha elide.

Ngokuqhelekileyo, indlela yokutshaja echazwe kwincwadana yefowuni yindlela yokutshaja eqhelekileyo efanelekileyo kwifowuni ephathekayo Ukongezelela, ifowuni ephathwayo okanye ishaja yebhetri ye-lithium iya kuyeka ngokuzenzekelayo emva kokuba ibhetri igcwele, kwaye akukho "i-trickle" yokutshaja ishaja yombane ye-nickel kwiiyure ze-10. Oko kukuthi, ukuba ibhetri yakho ye-lithium igcwele, iphinda itshaje emhlophe kwitshaja.

Kwaye ngubani na esingenakuqinisekisa ukuba iimpawu zokutshaja kunye nokukhutshwa kwesekethe yokukhusela ibhetri ayinakuze itshintshe kunye nomgangatho, ngoko ibhetri yakho iya kuba kwimida eyingozi. Esi sesinye isizathu sokuba sikuchase ukubizwa kwexesha elide Ukongezelela, emva kokuba intlawulo idlula ixesha elithile, ukuba ishaja ihlawuliswa, ukuba ishaja ayisuswanga, inkqubo ayigcini nje ukuyeka ukuhlawula, kodwa kunye nomjikelezo wokukhupha.

Mhlawumbi umenzi walo mkhuba unenjongo yakhe, kodwa kuyacaca ukuba ubomi bebhetri kunye neselula / ishaja ayilungile. Kwangaxeshanye, ukutshaja kwexesha elide kuthatha ixesha elide, kaninzi kufuneka kuqhutywe ebusuku, ngelixa kwigridi yamandla yelizwe lam, i-voltage kwiindawo ezininzi iphezulu kakhulu, kwaye kukho ukuguquguquka okukhulu. Njengoko kukhankanyiwe ngaphambili, ibhetri ye-lithium ithambile kakhulu, ingcono kakhulu kumandla ombane we-nickel ukuxhathisa kunye nokukhupha, ngoko oku kuzisa iingozi ezongezelelweyo.

 Ukongeza, enye inkalo yokungahoywa kukuba iibhetri ze-lithium nazo azifanelekanga ukukhutshwa ngokugqithiseleyo, kwaye ukukhutshwa ngokugqithiseleyo kuyingozi kakhulu kwiibhetri ze-lithium. Oku kuya kukhokelela kwezi ngxaki zilandelayo 2.

Ndiqale nini ukutshaja kusetyenziso oluqhelekileyo? Kwiforum yethu, unokubona rhoqo oku, kuba inani lentlawulo kunye nokukhutshwa lilinganiselwe, ngoko ibhetri yombane kufuneka ihlawulwe ngokusemandleni njengoko ilula. Kodwa ndifumene itafile yovavanyo yebhetri ye-lithium-ion kunye nomjikelo wokukhupha, kwaye idatha kubomi belophu zidweliswe ngezantsi.: Ubomi bomjikelo (10% DOD):> 1000 amaxesha Cycle ubomi (100% DOD):> 200 amaxesha I-DOD sisishunqulelo sobunzulu bokukhupha Njengoko kunokubonwa kwitheyibhile, inani lamaxesha inani lentlawulo kunye nobunzulu bokukhutshwa, ubomi bomjikelezo we-10% DOD bude kakhulu kune-100% DOD.

Ewe kunjalo, ukuba ilingana nomthamo opheleleyo wokutshaja: 10% * 1000 = 100% * 200 = 200, intlawulo yokugqibela epheleleyo kunye nokukhutshwa kusengcono, kodwa intetho ye-netizen yangaphambili kufuneka ihlonyelwe: Phantsi kweemeko eziqhelekileyo, kuya kufuneka ugcine amandla aseleyo ngokuhambelana nebhetri Ukutshaja umgaqo wokuyisebenzisa, kodwa ukuba ibhetri yakho kulindeleke ukuba ibe ngosuku lwesibini Xa unako ukunamathela kwikhosi, kufuneka uqalise ukutshaja ngexesha lonke. ukuthwala itshaja ukuya eofisini nako kuyinyani Kwaye xa kufuneka uhlawule ukujamelana nesiganeko esibalulekileyo ekulindeleke ukuba ikhokelele kunxibelelwano oluxakekileyo, nakwibhetri Xa kukho ibhalansi eninzi, ngoko uhlawula kuphela kwangaphambili, kuba awulahlekelwa ngokwenene "1" amaxesha okuhlawula umjikelo wobomi, Ngamaxesha "0.X", kwaye kaninzi kuncinci ukuba kuncinci.

 Umgaqo webhetri eseleyo yombane awuyi kudlula ngokugqithiseleyo. Ingxelo ethandwa kakhulu njengokutshaja okude, Oko kukuthi, zama ukusebenzisa ibhetri yebhetri, kungcono ukusebenzisa ukuvala ngokuzenzekelayo. “Olu qheliselo lukwenza nje ibhetri yenickel.

 Injongo kukuphepha imiphumo yememori, ngelishwa iphinda ijikeleze kwibhetri ye-lithium. Ndandidla ngokuba nebhetri yeselula Emva kokuba isilumkiso esisezantsi sibonakala, ayikahlawuliswa ukuqhubeka nokusebenzisa umzekelo wokuvala ngokuzenzekelayo. Iziphumo lo mzekelo kulo mzekelo Ukutshaja kamva kwaye akukho zimpendulo zazisebhuthini, kwaye kwafuneka bathumele uhlengahlengiso lwenkonzo yabathengi.

Oku kungenxa yebhetri ngenxa yokukhutshwa okugqithisileyo I-voltage iphantsi kakhulu, ukwenzela ukuba kungabikho iimeko eziqhelekileyo zokutshaja kunye nombane I-3, isenzo esichanekileyo se-lithium ibhetri yeefowuni eziphathwayo, iingcebiso zam ezibaluleke kakhulu zokuhlawula kunye nengxaki yokukhupha ekusebenziseni iibhetri ze-lithium.: 1.

Ukuhlawula ngokwexesha eliqhelekileyo kunye neprogram, namaxesha amathathu aphezulu; I-2, xa kukho i-tip ephantsi yefowuni, kufuneka uqale ukutshaja ngexesha; I-3, ukusebenza kweebhetri ze-lithium ayifuni indlela ekhethekileyo, kwaye ibhetri ye-lithium iya ngokwemvelo isebenze ekusebenziseni okuqhelekileyo kwefowuni. Ukuba unyanzelisa "ixesha lokuqala le-12-iyure ye-12 yokutshaja ixesha elide indlela yokutshaja", ayiyi kuba neziphumo. Ke ngoko, zonke iinkqubo ezilandela iiyure ezili-12 zokutshaja ixesha elide kunye nokusebenzisa iiselfowuni ze-lithium zebhetri ukuvala ngokuzenzekelayo ziphosakele.

Ukuba ubuqhele ukwenza ngokwengxelo engeyiyo, nceda uyilungise kwangethuba, mhlawumbi ayikashiywa lixesha Ewe kunjalo, kwimeko apho ifowuni ephathwayo kunye netshaja ngokwayo ikhusela kwaye ilawula umgangatho wesekethe, iqinisekisiwe. Ke ngoko, ukuqondwa kwemithetho yokutshaja kugxininiso, kwaye kwezinye iimeko kunokwenza eminye iminyinyiva.

Umzekelo, ukuba ufumanisa ukuba ifowuni kufuneka ihlawulwe ngaphambi kokuba ulale ebusuku, ungaqala ukutshaja ngaphambi kokuba ulale. Isitshixo sengxaki kukuba kufuneka uyazi ukuba yeyiphi indlela echanekileyo, kwaye ungayenzi ngabom ngokwengxelo engalunganga. .
