Kodwa zineengenelo ezininzi ezingenakukhutshwa ngesandla, kwaye zikwabeka ixabiso kwindawo efanelekileyo. Kodwa ngakumbi ngaloo nto kumacandelo ambalwa alandelayo.

Sasifumene iveni yethu entsha ngo-2018 ineebhetri ezimbini ze-AGM ngaphakathi. Sasingafuni ukuzilahla kwangoko kwaye sasicebe ukutshintshela kwi-lithium kuphela ekupheleni kobomi beebhetri ze-AGM. Nangona kunjalo, izicwangciso ziyaziwa ukuba ziyatshintsha, kwaye ukuze senze indawo kwiveni yokufakelwa kwesifudumezi sethu sedizili esizayo, ngoku sikhethe ukufaka ibhetri ye-lithium kwikhaya elihambayo. Siza kuxela ngale nto ngokweenkcukacha, kodwa ewe senze uphando oluninzi kwangaphambili, kwaye singathanda ukubonisa iziphumo kweli nqaku.

Iziseko zebhetri yeLithium

Okokuqala, iinkcazo ezimbalwa zokucacisa isigama.

Yintoni iLiFePo4?

Ngokuphathelele iibhetri ze-lithium zamakhaya aphathwayo, umntu udibana negama elithi LiFePo4 elinzima.

I-LiFePo4 yibhetri ye-lithium-ion apho i-electrode elungileyo iqulathe i-lithium iron phosphate endaweni ye-lithium cobalt oxide. Oku kwenza le bhetri ikhuseleke kakhulu njengoko ithintela ukufudumeza.

Ithetha ukuthini i-Y kwi-LiFePoY4?

Ukuze ufumane ukhuseleko, kwangethubaIibhetri zeLiFePo4yayine-wattage ephantsi.

Ekuhambeni kwexesha, oku kwachaswa ngeendlela ezahlukeneyo, umzekelo ngokusebenzisa i-yttrium. Ezi bhetri zibizwa ngokuba yiLiFePoY4, kwaye zikwafumaneka (ngokungaqhelekanga) kwiindlu eziphathwayo.

Ikhuselekile kangakanani ibhetri ye-lithium kwi-RV?

Njengabanye abaninzi, besizibuza ukuba iibhetri ze-lithium zikhuselekile kangakanani xa zisetyenziswa kwiimotorhomes. Kwenzeka ntoni kwingozi? Kwenzeka ntoni ukuba ngempazamo utshaja imali engaphezulu?

Enyanisweni, kukho iingxaki zokhuseleko kwiibhetri ezininzi ze-lithium-ion. Yiyo loo nto kuphela uhlobo lweLiFePo4, oluthathwa njengolukhuselekileyo, olusetyenziswa kwicandelo lekhaya eliphathwayo.

Uzinzo lomjikelo weebhetri ze-lithium

Kwixesha lophando lwebhetri, umntu udibana namagama athi “uzinzo lomjikelo” kunye “neDoD”, anxulumeneyo. Kuba uzinzo lomjikelo yenye yeenzuzo ezinkulu zebhetri ye-lithium kwikhaya eliphathwayo.

Igama elithi “DoD” (Ubunzulu bokukhupha) ngoku libonisa ukuba ibhetri ikhutshwa kangakanani. Ngoko ke izinga lokukhupha. Kuba ke ngoko kwenza umahluko nokuba ndikhupha ibhetri ngokupheleleyo (100%) okanye yi-10% kuphela.

Uzinzo lomjikelo ngoko ke lunengqiqo kuphela ngokunxulumene nenkcazo yeDoD. Kuba ukuba ndikhupha ibhetri ukuya kwi-10% kuphela, kulula ukufikelela kumawaka amaninzi emijikelo - kodwa oko akufanele kube yinto enokwenzeka.

Oko kungaphezulu kakhulu kunokuba iibhetri ze-lead-acid eziqhelekileyo zinokukwenza.

Ngokutshintsha kwethu okuzayo ukusuka kwi-AGM ukuya kwiibhetri ze-lithium, siza kuphinda kathathu amandla ethu asebenzisekayo ngelixa sithatha indawo encinci.

Ubomi bebhetri yeLithium

Ubomi bebhetri ye-lithium kwikhaya eliphathwayo bunokuba bukhulu kakhulu.

Oku kuqala ngento yokuba ukutshaja ngokuchanekileyo kulula kwaye akukho nzima, kwaye akulula kangako ukuchaphazela ubomi benkonzo ngokutshaja gwenxa kunye nokukhupha umbane nzulu.

Kodwa iibhetri ze-lithium nazo zinozinzo olukhulu lomjikelo.

Umzekelo:

Masithi ufuna amandla apheleleyo ebhetri ye-lithium eyi-100Ah yonke imihla. Oko kuthetha ukuba ubuya kufuna ibhayisekile enye ngemini. Ukuba ubusendleleni unyaka wonke (oko kukuthi iintsuku ezingama-365), ubuya kuqhubeka nebhetri yakho ye-lithium iminyaka engama-3000/365 = iminyaka eyi-8.22.

Nangona kunjalo, uninzi lwabahambi akunakwenzeka ukuba babe seluhambeni unyaka wonke. Endaweni yoko, ukuba sicinga ukuba iiveki ezi-6 zeholide = iintsuku ezingama-42 size songeze iimpelaveki ezimbalwa kwi-100 yeentsuku zokuhamba ngonyaka, ngoko siya kuba sikwi-3000/100 = iminyaka engama-30 yobomi. Kukhulu, akunjalo?

Akufuneki ilibaleke: Inkcazo ibhekisa kwi-90% ye-DoD. Ukuba ufuna amandla amancinci, ubomi benkonzo buyandiswa. Ungakulawula oku ngokukhutheleyo. Uyazi ukuba udinga i-100Ah imihla ngemihla, ngoko ungakhetha ibhetri enkulu kabini. Kwaye nge-swoop enye ubuya kuba ne-DoD eqhelekileyo ye-50% kuphela eya kwandisa ubomi. Ngalo ndlela: Ibhetri ehlala ixesha elide ngaphezu kweminyaka engama-30 mhlawumbi ingatshintshwa ngenxa yenkqubela phambili yetekhnoloji elindelekileyo.

Ubomi obude benkonzo kunye nomthamo ophezulu nosebenzisekayo nako kubeka ixabiso lebhetri ye-lithium kwikhaya eliphathwayo kwindawo efanelekileyo.

Umzekelo:

Ibhetri yeBosch AGM ene-95Ah okwangoku ixabisa malunga ne-$200.

Kufuneka kusetyenziswe malunga ne-50% kuphela ye-95Ah yebhetri ye-AGM, oko kukuthi i-42.5Ah.

Ibhetri ye-lithium yeLiontron RV enomthamo ofanayo we-100Ah ixabisa i-$1000.

Ekuqaleni oko kuvakala ngathi ixabiso lebhetri ye-lithium liphindwe kahlanu. Kodwa ngeLiontron, kungasetyenziswa amandla angaphezu kwama-90%. Kumzekelo, ihambelana neebhetri ezimbini ze-AGM.

Ngoku ixabiso lebhetri ye-lithium, elungiselelwe amandla asetyenziswayo, lisengaphezulu kwesibini.

Kodwa ngoku uzinzo lomjikelo luqala ukusebenza. Apha ulwazi lomenzi luyahluka kakhulu - ukuba ungafumana naluphi na (ngeebhetri eziqhelekileyo).

• Ngeebhetri ze-AGM umntu uthetha ngeebhayisekile ezifikelela kwi-1000.
• Nangona kunjalo, iibhetri zeLiFePo4 zibhengezwa njengezineebhayisekile ezingaphezu kwama-5000.

Ukuba ibhetri ye-lithium ekwikhaya eliphathwayo ihlala imijikelo ephindwe kahlanu, ngoko keibhetri ye-lithiumiza kudlula ibhetri ye-AGM ngokwexabiso nokusebenza.
