Iibhetri zeLithium-ion: isikhokelo sokuthenga umatiloshe

U-Andrew wachaza ukuba kutheni umgangatho kufuneka ukhethwe xa ufaka iibhetri ze-lithium-ion, kunye neebhetri ze-lithium zentsimbi ze-phosphate kwimarike esiyikhethileyo.
Iibhetri zeLithium zikhaphukhaphu kakhulu kunelead-asidi kwaye ngokwethiyori ziphantse zibe kabini umthamo weasidi yelothe.
Isitshixo sofakelo oluyimpumelelo lokwenene lweebhetri ze-lithium-ion, kwabo bafuna ukwamkela iteknoloji entsha yebhetri okanye bazinikele kwizikhephe zombane, kukusebenzisa inkqubo yokubeka iliso yebhetri ye-lithium-ion ephezulu (BMS) ngokufanayo. umgangatho wodidi lokuqala.
I-BMS engcono kakhulu iya kulungelelaniswa kwimeko yofakelo, ngelixa i-BMS embi kakhulu iya kuba lukhuseleko olubi kuphela ukuphepha ukuchithwa okupheleleyo.
Ukuba injongo yakho kukuba nenkqubo yokugcina amandla ekhuselekileyo, ethembekileyo neyomeleleyo ebhodini, ungazami ukonga imali kwi-BMS.
Kodwa ukwenza izinto zibe zibi nakakhulu, kwimeko yezixhobo ze-lithium-ion, ekuhambeni kwexesha, ukusebenzisa amacandelo aphantsi, awenziwe kakubi akayi kuchitha imali eninzi kuphela, kodwa kubangele ingozi enkulu yomlilo ebhodini.
Ibhetri ye-LiFePO4 ibhengezwa njengeyona "plug-in" efanelekileyo yokutshintshwa kwebhetri yeasidi ngaphandle kwesidingo sezixhobo zokutshaja ezongezelelweyo.
Kuthiwa iyahambelana nazo zonke iitshaja ze-lead-acid kunye neziguquli ze-DC-to-DC ezikhoyo ngoku kwimarike.Bane-BMS eyakhelwe ngaphakathi ekwazi ukubeka iliso kunye nokulawula imisebenzi yabo yokutshaja kunye nokukhupha ukuze kuqinisekiswe ukhuseleko oluphezulu, ukuthembeka kunye nobomi obude.
I-LiFePO4 i-35% ilula kuneebhetri ze-lead-asidi ezilinganayo kunye ne-40% encinci ngobukhulu.Inokukhutshwa okuphezulu kwamandla (<1kW/120A), izinga lentlawulo ye-1C kunye nokukwazi ukubonelela ukuya kuma-2,750 imijikelezo phantsi kwe-90% ye-DoD, okanye ukuya kwi-5,000-50%.% DoDukukhazekaumjikelo.
Inkampani yaseDatshi iVictron iyaziwa ngeemveliso zayo zombane ezikumgangatho ophezulu, ibonelela nge-60-300Ah amandla "plug-in" iibhetri ze-LFP, ezifanelekileyo kwi-12.8 okanye i-25.6V yofakelo, xa ikhutshwe kwi-80% ye-DoD okanye ukuya kwi-5,000 imijikelezo, iyakwazi. ukubonelela nge-2,500 Kuphela ngama-50% kumjikelo ngamnye.
Iithegi ze-Smart zithetha ukuba banokusebenzisa imodyuli edibeneyo yeBluetooth ukubeka iliso kude, kodwa bafuna i-Victron yangaphandle ye-VE.Bus BMS.
Umda wokukhutshwa kwangoku ngu-100A nge-100Ah, kwaye inani eliphezulu leebhetri ngokuhambelanayo yi-5.
Ezi bhetri ze-LFP zokufakelwa kweplagi zine-BMS eyakhelweyo kunye neradiyetha eyodwa yokupholisa ibhetri ngelixa itshaja.
I-IHT "plug-in" 100Ah LiFePo4 ibhetri evela kwi-brand eyaziwayo ye-LFP Battle Wazalelwa e-United States inokwamkela ukutshaja kwe-1C kunye ne-100A yokukhupha ngoku (i-200A iphezulu kwimizuzwana ye-3 kuphela) ngaphandle komonakalo.
Zikwabandakanya i-BMS eyakhelwe-ngaphakathi ebanzi ekwazi ukulawula i-voltage thresholds, ubushushu, ibhalansi yebhetri, kunye nokubonelela ngokhuseleko lwesekhethi emfutshane.
Itekhnoloji yobunini beFirefly ibandakanya igwebu lecarbon-based porous enamawaka eeseli ezivulekileyo ezisasaza i-sulfuric acid electrolyte kwindawo ebanzi ukuphucula ukusebenza kakuhle kwekhemistry ye-lead-acid.
"I-microbattery" kwisakhiwo se-carbon foam electrolyte sinokufikelela kwizinga eliphezulu lokukhupha ngoku, ukwandisa ubuninzi bamandla kunye nokwandisa ubomi bomjikelezo (<3x).
Ikwavumela ukutshaja okukhawulezayo xa kuthelekiswa neebhetri ze-asidi ekhokelayo, efanelekile xa itshaja ukusuka kwindawo emiselweyo yokutshaja efana nelanga okanye ialternator.
Iifireflies zixhathisa ngokugqithisileyo kwi-sulfate kwaye zinokusetyenziswa kunye neetshaja ezisemgangathweni ze-lead-acid kunye ne-alternator regulators.
Kwezi bhetri ze-glass fibre mat (AGM) ezinzulu, kuthiwa i-carbon cathode yonyusa ukwamkelwa kwentlawulo, ngaloo ndlela ikhawulezisa inkqubo yokutshaja ibhetshi, ukwandisa inani lemijikelo ekhoyo kunye nokunciphisa i-sulfate eyonakalisayo yamacwecwe.
Ibhetri yekristale ekhokelayo i-asidi ehamba phambili etywiniweyo (i-SLA) esebenzisa i-electrolyte ye-SiO2 engagqwaliyo, engagqwalisiyo eya kuthi icwebezele ngokuhamba kwexesha, iyenze ibe yomelele kwaye iphucule ukusebenza.
I-high-purity lead-calcium-selenium electrode plate kunye ne-electrolyte zigcinwe kwi-pad microporous, ngoko isantya sokutshaja kwebhetri siphindwe kabini kune-SLA eqhelekileyo, ukukhutshwa kunzulu, umjikelo udla ngokuphindaphindiweyo, kwaye usetyenziswa ngakumbi. amaqondo obushushu agqithisileyo kuneebhetri ze-lithium-ion kwaye ibonelela ngokusebenza ngcono Ezinye ii-AGM ezininzi zinobomi obude benkonzo.
