U-Andrew uchaze ukuthi kungani kufanele kukhethwe ikhwalithi lapho kufakwa amabhethri e-lithium-ion, kanye namabhethri e-lithium iron phosphate angcono kakhulu emakethe esiwakhethile.
Amabhethri e-lithium alula kakhulu kune-asidi yomthofu futhi ngokomqondo anomthamo ophindwe kabili we-asidi yomthofu.
Isihluthulelo sokufakwa ngempumelelo kwamabhethri e-lithium-ion, kulabo abafuna ukusebenzisa ubuchwepheshe obusha bebhethri noma ngisho ukuzinikela ezikebheni zikagesi, ukusebenzisa isistimu yokuqapha ibhethri ye-lithium-ion yezinga eliphezulu (BMS) ngokufanayo. izinga lokuqala.
I-BMS ehamba phambili izofanelana nesimo sokufakwa, kuyilapho i-BMS embi kakhulu izoba isivikelo esinzima ukugwema ukuwohloka okuphelele.
Uma umgomo wakho kuwukuba nesistimu yokugcina amandla ephephile, ethembekile futhi ehlala isikhathi eside, ungazami ukonga imali ethile ku-BMS.
Kodwa ukwenza izinto zibe zimbi nakakhulu, esimweni semishini ye-lithium-ion, ngokuhamba kwesikhathi, ukusebenzisa izingxenye ezishibhile, ezikhiqizwa kabi ngeke nje kuchithe imali eningi, kodwa futhi kubangele ingozi enkulu yomlilo ebhodini.
Ibhethri ye-LiFePO4 ikhangiswa njengendawo ekahle yebhethri ye-lead-acid "plug-in" ngaphandle kwesidingo semishini yokushaja eyengeziwe.
Kuthiwa ihambisana nawo wonke amashaja e-lead-acid kanye neziguquli ze-DC-to-DC ezisemakethe njengamanje.Bane-BMS eyakhelwe ngaphakathi ekwazi ukuqapha nokulawula imisebenzi yabo yokushaja nokukhipha ukuze kuqinisekiswe ukuphepha okuphezulu, ukwethembeka nempilo ende.
I-LiFePO4 ilula ngo-35% kunamabhethri e-lead-asidi efanayo kanye namabhethri angama-40% amancane ngosayizi.Inamandla okukhipha aphezulu (<1kW/120A), izinga lokushaja elingu-1C kanye nekhono lokuhlinzeka ngemijikelezo efika ku-2,750 ngaphansi kuka-90% we-DoD, noma kufika ku-5,000-50%.% DoD
umjikelezo.
Inkampani yaseDashi iVictron yaziwa ngemikhiqizo yayo kagesi yekhwalithi ephezulu, ehlinzeka ngamabhethri e-LFP "plug-in" angu-60-300Ah, afanele ukufakwa okungu-12.8 noma okungu-25.6V, lapho ekhishwa ku-80% we-DoD noma kufika kuma-5,000 cycles, angakwazi. hlinzeka ngo-2,500 Kuphela ama-50% ngomjikelezo ngamunye.
Omaka abahlakaniphile basho ukuthi bangasebenzisa imojuli ehlanganisiwe ye-Bluetooth ukuze baqaphe ukude, kodwa badinga i-Victron VE.Bus BMS yangaphandle.
Umkhawulo wamanje wokukhipha ngu-100A nge-100Ah ngayinye, futhi inombolo enkulu yamabhethri ngokuhambisana ngu-5.
Lawa mabhethri e-LFP angena esikhundleni se-plug ane-BMS eyakhelwe ngaphakathi kanye nerediyetha ehlukile yokupholisa ibhethri ngenkathi ishaja.
Ibhethri le-IHT "plug-in" 100Ah LiFePo4 elivela kumkhiqizo owaziwayo we-LFP Battle Wazalelwa e-United States ingamukela ukushaja okungu-1C kanye nokukhipha okungu-100A (ukuphakama okungu-200A kumasekhondi angu-3 kuphela) ngaphandle kokulimala.
Futhi zifaka phakathi i-BMS eyakhelwe ngaphakathi ebanzi engaphatha ama-voltage thresholds, izinga lokushisa, ibhalansi yebhethri, futhi inikeze ukuvikelwa kwesekethe emfushane.
Ubuchwepheshe bobunikazi beFirefly buhlanganisa igwebu elisuselwe kukhabhoni elinezimbotshana ezinezinkulungwane zamaseli avulekile asabalalisa i-sulfuric acid electrolyte endaweni ebanzi ukuze kuthuthukiswe ukusebenza kahle kwekhemistri ye-asidi yomthofu.
"I-microbattery" esakhiweni se-carbon foam electrolyte ingafinyelela izinga eliphezulu lokukhishwa kwamanje, ikhulise ukuminyana kwamandla futhi inwebe impilo yomjikelezo (<3x).
Iphinde ivumele ukushaja okusheshayo uma kuqhathaniswa namabhethri e-lead-asidi evamile, alungile uma eshajwa kusukela kumthombo wokushaja wesikhathi esilinganiselwe njengelanga noma i-alternator.
Okhanyikhanyi bamelana kakhulu ne-sulfate futhi bangasetshenziswa namashaja ajwayelekile ezigaba eziningi ze-lead-acid kanye nezilawuli ezishintshashintshayo.
Kulawa mabhethri e-deep-cycle absorption glass fiber mat (AGM), i-carbon cathode kuthiwa inyusa ukwamukelwa kwenkokhelo, ngaleyo ndlela isheshise inqubo yokushaja iqoqo, ikhulise inani lemijikelezo etholakalayo futhi inciphise ukugcwala okulimazayo kwamapuleti.
Ibhethri yekristalu eholayo iyi-asidi eholayo evaliwe (i-SLA) esebenzisa i-electrolyte ye-SiO2 acid esungula izinto ezintsha, engagqwali ezocwebezela ngokuhamba kwesikhathi, iyenze ibe namandla futhi ithuthukise ukusebenza.
I-high-purity lead-calcium-selenium electrode plate kanye ne-electrolyte kugcinwa kuphedi ye-microporous, ngakho-ke isivinini sokushaja sebhethri siphindwe kabili kune-SLA evamile, ukukhishwa kujulile, umjikelezo uvame kakhulu, futhi usetshenziswa ngaphezulu. amazinga okushisa eqile kunamabhethri e-lithium-ion futhi inikeza ukusebenza okungcono Amanye ama-AGM amaningi anempilo ende yesevisi.

Ubuchwepheshe bakamuva belanga benza ukuhamba ngomkhumbi okuzimele kube lula ukukufeza.UDuncan Kent unikeza indaba yangaphakathi yakho konke okudingayo...
U-Duncan Kent wafunda ubuchwepheshe obusetshenziswa kumabhethri e-lithium futhi wachaza izici okufanele zicatshangelwe lapho eqhathaniswa nabaphathi...
Ngokusebenzisa lobu buchwepheshe obuhlanzekile obungenayo i-cadmium noma i-antimony, ibhethri lekristalu eliholayo lingaphinda lisetshenziswe kuze kufike ku-99%, futhi okubaluleke nakakhulu, lihlukaniswa njengento yokuhamba engeyona ingozi.
