Intshayelelo:
Iibhetri ziyinxalenye ebalulekileyo yezixhobo ezininzi kunye neenkqubo, ukusuka kwiifowuni eziphathwayo kunye neelaptops ukuya kwiimoto kunye nendawo yokugcina amandla elanga. Ukwazi uhlobo lwebhetri oyisebenzisayo kubalulekile ngeenjongo zokhuseleko, ukugcinwa kunye nokulahla. Iintlobo ezimbini eziqhelekileyo zeebhetri zezii-lithium-ion (i-Li-ion)kunye neebhetri ze-lead-acid. Uhlobo ngalunye luneempawu zalo kwaye lufuna ukuphathwa ngendlela eyahlukileyo. Kweli nqaku, siza kuxoxa ngendlela yokwazi ukuba ibhetri yi-lithium okanye yi-lead, kunye nomahluko ophambili phakathi kwezi zimbini.
Inkangeleko
Enye yezona ndlela zilula zokwahlula phakathi kweebhetri ze-lithium kunye ne-lead-acid kukujonga inkangeleko yazo. Iibhetri ze-lead-acid ngokubanzi zinkulu kwaye zinzima kuneebhetri ze-lithium kunye ne-lead-acid.iibhetri ze-lithium-ion.Zihlala zimile okwesikwere okanye zibume obufanayo kwaye zinesiciko esikhethekileyo sokufaka umoya ngaphezulu ukuze kongezwe amanzi. Xa kuthelekiswa, iibhetri ze-lithium-ion zihlala zincinci, zikhaphukhaphu, kwaye ziza ngeemilo ezahlukeneyo, kuquka i-cylindrical kunye ne-prismatic. Azinazo izigqubuthelo zomoya kwaye zihlala zifakwe kwibhokisi yeplastiki.
Iithegi kunye neethegi
Enye indlela yokuchonga uhlobo lwebhetri kukujonga iilebhile kunye neempawu kwibhetri ngokwayo. Iibhetri ze-lead-acid zihlala zineelebhile ezinje, kwaye zinokuba neempawu ezibonisa i-voltage kunye nomthamo. Ukongeza, iibhetri ze-lead-acid zihlala zineelebhile zesilumkiso malunga neengozi ze-sulfuric acid kunye nesidingo somoya ofanelekileyo. Iibhetri ze-lithium-ion, kwelinye icala, zihlala ziphawulwa ngolwazi malunga nokwakheka kweekhemikhali, i-voltage, kunye nomthamo wamandla. Zisenokuba neempawu ezibonisa ukuthotyelwa kwemigangatho yokhuseleko, njenge-UL (Underwriters Laboratories) okanye i-CE (European Conformity Assessment).
I-Voltage kunye nomthamo
I-voltage kunye nomthamo webhetri nazo zinokunika izikhokelo malunga nohlobo lwayo. Iibhetri ze-lead-acid zihlala zifumaneka kwii-voltage ze-2, 6, okanye 12 volts kwaye zihlala zisetyenziswa kwizicelo ezifuna amandla aphezulu ombane, njengeebhetri zokuqalisa imoto. Iibhetri ze-lithium-ion, kwelinye icala, zinobunzima obuphezulu bamandla, kunye nee-voltage eziqala kwi-3.7 volts kwiseli enye ukuya kwi-48 volts nangaphezulu kwiipakethi ezinkulu zebhetri ezisetyenziswa kwizithuthi zombane okanye kwiinkqubo zokugcina amandla.
Iimfuno zolondolozo
Ukuqonda iimfuno zokugcinwa kwebhetri kunokunceda ekuchongeni uhlobo lwayo. Iibhetri ze-lead-acid zifuna ukulungiswa rhoqo, kubandakanya ukujonga nokugcwalisa amanqanaba e-electrolyte ngamanzi acocekileyo, ukucoca iiterminals, kunye nokuqinisekisa umoya ofanelekileyo ukuthintela ukuqokelelana kwegesi ye-hydrogen eqhumayo. Ngokwahlukileyo koko,iibhetri ze-lithium-ionazinazo izinto ezigcinwayo kwaye azifuni kunkcenkceshelwa rhoqo okanye ukucocwa kwesiphelo. Nangona kunjalo, kufuneka zikhuselwe ekutshajisweni kakhulu nasekukhutshweni kwamanzi anzulu ukuthintela umonakalo nokuqinisekisa ukuba zihlala ixesha elide.
Impembelelo kwindalo esingqongileyo
Impembelelo yebhetri kwindalo inokuba yinto ephambili ekufuneka iqwalaselwe xa kuchongwa uhlobo lwebhetri. Iibhetri ze-lead-acid ziqulathe i-lead kunye ne-sulfuric acid, zombini ezinokuba yingozi kwindalo ukuba azilawulwa kakuhle. I-lead yintsimbi enzima enetyhefu kwaye i-sulfuric acid iyatsha kwaye inokubangela ungcoliseko lomhlaba namanzi ukuba ayiphathwanga kwaye ilahlwe kakuhle. Iibhetri ze-lithium-ion zikwazisa imingeni kwindalo ngenxa yokutsalwa kwe-lithium kunye nezinye iintsimbi zomhlaba ezinqabileyo, ezinokukhokelela ekubalekeni kobushushu kunye nemililo ukuba aziphinda zisetyenziswe ngokufanelekileyo. Ukuqonda impembelelo yebhetri kwindalo kunokukunceda wenze izigqibo ezinolwazi malunga nokusetyenziswa kunye nokulahla ibhetri.
Ukulahlwa kunye nokurisayikilishwa
Ukulahlwa ngokufanelekileyo kunye nokurisayikilisha iibhetri kubalulekile ekunciphiseni impembelelo yokusingqongileyo kunye nokuqinisekisa ukuba izinto ezixabisekileyo ziyafunyanwa. Iibhetri ze-lead-acid zihlala zirisayikilishwa ukuze zifumane i-lead kunye neplastiki, ezinokusetyenziselwa ukwenza iibhetri ezintsha kunye nezinye iimveliso. Ukuphinda kurisayikilishe iibhetri ze-lead-acid kunceda ukuthintela ungcoliseko lwe-lead kunye nokugcina izixhobo zendalo.Iibhetri zeLithium-ionikwaqulathe izinto ezixabisekileyo ezifana ne-lithium, i-cobalt kunye ne-nickel, ezinokuphinda zisetyenziswe kwaye zisetyenziswe kwakhona kwiibhetri ezintsha.
