Intshayelelo:
Iibhetri zeLithiumziye zithandwa kakhulu kwizicelo ezahlukeneyo ngenxa yokuxinana kwamandla aphezulu, ubomi obude, ubunzima obulula kunye neempawu ezihambelana nokusingqongileyo. Lo mkhwa uye wanda ukuya kwiinqwelo zegalufa, kunye nabavelisi abaninzi ngakumbi nangakumbi bekhetha iibhetri ze-lithium ukuze zithathe indawo yeebhetri ze-asidi zemveli. Nangona kunjalo, inkxalabo eqhelekileyo phakathi kwabanikazi beenqwelo zegalufa yinto enokwenzeka yokuhlawula iibhetri ze-lithium kunye nefuthe layo ekusebenzeni kunye nokuphila ixesha elide.
Ukuqonda Ukutshaja ibhetri yeLithium
Ukuze kulungiswe le ngxaki, kubalulekile ukuqonda kuqala iziseko zokutshaja ibhetri ye-lithium. Ngokungafaniyo neebhetri ze-lead-asidi,iibhetri ze-lithiumzifuna iiprothokholi zokutshaja ezikhethekileyo zokuqinisekisa ukusebenza okugqwesileyo kunye nokhuseleko. Inkqubo yokutshaja ngokuqhelekileyo ibandakanya izigaba ezibini: i-current current (CC) kunye ne-voltage eqhubekayo (CV).
Ngexesha lesigaba sangoku esingaguqukiyo, ibhetri ihlawulisa ngesantya esizinzileyo de ifike kumbane oqingqwe kwangaphambili. Nje ukuba lo mbane ufikeleleke, itshaja itshintshela kwisigaba sombane esingaguqukiyo, apho i-voltage ihlala ingaguquguquki ngelixa ikhoyo iyancipha kancinci kancinci. Le nkqubo yokutshaja enamanqanaba amabini yenzelwe ukwandisa ubomi bebhetri kunye nokusebenza.
Impembelelo yokuTshaja ngokugqithisileyo
Ukutshaja okugqithisileyo kwenzeka xa amandla ombane wokutshaja ebhetri agqithise kwinqanaba elicetyiswayo. Oku kunokukhokelela kuluhlu lweengxaki, kubandakanywa ubomi obufutshane bebhetri, ukucutha umthamo kunye, kwiimeko ezinzima, ukubaleka kwe-thermal kunye nemililo. Xa kuziwa kwiibhetri zenqwelo yegalufa, ukutshaja kakhulu kunokuchaphazela kakhulu ukusebenza ngokubanzi kunye nobomi bebhetri ye-lithium-ion.
Enye yeengxaki eziphambili ngokugqithiswa kwemaliiibhetri zenqwelo yegalufa ye-lithiumkukuba ubomi bomjikelo bunokuncitshiswa. Ubomi bomjikelo bubhekiselele kwinani lemijikelo yokukhupha intlawulo ibhetri enokuthi igqithe phambi kokuba umthamo wayo uwele ngaphantsi komqobo othile. Ukutshaja ngokugqithiseleyo kukhawulezisa ukuthotywa kwezinto ezisebenzayo zebhetri, okukhokelela kubomi bomjikelo obucuthiweyo kunye nobomi bubonke.
Ukongeza kubomi bomjikelo obufutshane, ukutshaja kakhulu kunokubangela ukonyuka kokumelana nebhetri kwangaphakathi. Oku kunokubangela ubushushu bokusebenza obuphezulu, ukusebenza kakuhle kwamandla asezantsi, kunye nokusebenza okuphantsi kukonke. Kwimeko yeenqwelo zegalufa, ezi mpembelelo zinokukhokelela ekuncitshisweni koluhlu lokuqhuba, ukuhla kwamandla ombane, kwaye ekugqibeleni amava omsebenzisi athotyiwe.

Ukuthintela ukuTshaja kakhulu
Ukunciphisa umngcipheko wokutshaja okugqithisileyo, abanini beenqwelo zegalufa nabaqhubi kufuneka baziqhelanise neendlela ezifanelekileyo zokutshaja kwaye basebenzise iitshaja ezilungiselelwe ngokukodwa iibhetri ze-lithium-ion. Oku kuquka ukusebenzisa itshaja exhotyiswe ngamandla ombane kunye neendlela zolawulo lwangoku ukuthintela ukutshaja okugqithisileyo, kunye nokubambelela kwiprothokholi yokutshaja ekhuthazwa ngumenzi.
Kwangaxeshanye, ukuphumeza ainkqubo yolawulo lwebhetri (BMS)inokunika umaleko owongezelelweyo wokhuselo ngokuchasene nokutshaja kakhulu kunye neminye imiba enokubakho. Iisistim ze-BMS ziyilelwe ukujonga nokulinganisa amandla ombane eseli nganye, ukuqinisekisa ukuba iibhetri zisebenza ngaphakathi kwemida ekhuselekileyo kunye nokuthintela ukutshajiswa okanye ukutshajwa ngaphantsi kweeseli ezithile.
Ukuqukumbela
Ukuhlawula ngaphezulu aibhetri yenqwelo yegalufa ye-lithiuminokuba neziphumo ezibi ekusebenzeni kwayo, ixesha lokuphila, kunye nokhuseleko. Kubalulekile ukuqonda iimfuno zokutshaja iibhetri ze-lithium kwaye usebenzise iitshaja ezifanelekileyo kunye neeprothokholi zokutshaja ukuthintela ukutshaja kakhulu. Ukulandela izikhokelo zomenzi, ukusebenzisa iitshaja ezihambelanayo, kwaye, xa zikhoyo, ukuthembela kwiiNkqubo zoLawulo lweBattery eyakhelwe-ngaphakathi kunokunceda ukuqinisekisa ubomi obude kunye nokhuseleko lweebhetri zenqwelo yegalufa ye-lithium. Ngokuthatha la manyathelo okhuseleko, abanini benqwelo yegalufa banokonwabela izibonelelo zebhetri ye-lithium ngelixa besandisa ubomi babo kwaye benciphisa umngcipheko onokuthi ubekho.
