Ibhetri yokugcina amandla elanga ibamba umbane ogqithisileyo kwiipaneli zelanga emini kwaye iwugcine njengamandla ekhemikhali ngokusebenzisa inkqubo ye-electrochemical. Xa umbane ufuneka ebusuku okanye ngexesha lokucima, ibhetri iwaguqula loo mandla ekhemikhali abuyele kumbane ukuze asebenze kwikhaya lakho.
Indlela engundoqo yebhetri yokugcina amandla elanga ibandakanya ii-ion ze-lithium ezihamba phakathi kwee-electrode ezimbini-i-anode kunye ne-cathode{1}}ngesisombululo se-electrolyte. Ngexesha lokutshaja, amandla elanga aqhuba i-ion ukusuka kwi-cathode ukuya kwi-anode. Ngexesha lokukhutshwa, ii-ion zibuyela umva, zikhupha ii-electron ezenza umbane osetyenziswa ekhayeni lakho.
Inkqubo ye-Electrochemical emva koGcino lwaMandla
I-chemistry ngaphakathi kwebhetri yokugcina amandla elanga inquma indlela esebenzayo ngayo ukugcina nokukhulula amandla. Uninzi lweebhetri zelanga zokuhlala zisebenzisa i-lithium-iteknoloji ye-ion, ngokukodwa i-lithium iron phosphate (LiFePO4) okanye imiqulu ye-nickel manganese cobalt (NMC).
Ngaphakathi kwiseli nganye yebhetri, amacandelo amahlanu angundoqo asebenza kunye. I-anode, eqhele ukwenziwa kwigraphite, isebenza njengetheminali engalunganga apho ii-ion ze-lithium ziqokelelana ngexesha lokutshaja. I-cathode-itheminali evumayo{3}}iqulethe iioksidi zesinyithi ezikhupha ii-ion zelithium xa ibhetri itshaja. Phakathi kwabo kuhleli isahluli, inwebu encinci enemingxuma ethintela ukudibana ngokuthe ngqo ngelixa ivumela ukunyakaza kwe-ion.
Isisombululo se-electrolyte sisebenza njengendlela yokuthutha. Olu lwelo okanye ijeli iqulethe iityuwa ze-lithium ezenza ukuba i-ion ihambe phakathi kwee-electrodes. Abaqokeleli bangoku abenziwe ngobhedu kunye ne-aluminium badibanisa i-chemistry yangaphakathi kwi-wiring yangaphandle.
Xa iiphaneli zelanga zivelisa umbane, loo msinga ngqo ingena ebhetrini. Amandla ombane anyanzela ii-ion ze-lithium ukuba ziphume kwisakhiwo se-cathode kwaye zifuduke nge-electrolyte ukuya kwi-anode. Ngaxeshanye, ii-electron zihamba ngesekethe yangaphandle ukuze zilungelelanise intlawulo. Le nkqubo igcina amandla kwiibhondi zekhemikhali ngaphakathi kwezixhobo zebhetri.
Umva kwenzeka xa ufuna amandla. Iiion zeLithium zibuyela umva ukusuka kwi-anode ukuya kwi-cathode nge-electrolyte yangaphakathi, ngelixa ii-electron zihamba kwinkqubo yombane yekhaya lakho, zinika amandla izixhobo zombane endleleni. I-Battery Management System (BMS) ibeka iliso le nkqubo ngokuqhubekayo, i-voltage yokulandelela, i-current, kunye neqondo lokushisa ukuthintela ukutshaja ngokugqithiseleyo okanye ukukhutshwa okugqithisileyo okunokonakalisa iiseli.
Ukujikeleza-ubuchule bohambo bulinganisa ukuba angakanani amandla owafumanayo emva koko ufake kuyo. Ngokuka US Energy Information Administration, usetyenziso{4}}isikali se-lithium{5}}iisistim ze-ion zifikelela kuqikelelo lwama-82%. Iibhetri ze-LiFePO4 ezikumgangatho ophezulu zingafikelela kuma-90{11}}95% ukusebenza kakuhle, oku kuthetha ukulahleka kwamandla okuncinci ngexesha lomjikelo wokukhupha intlawulo.
Indlela Udibaniso lweSolar lusebenza ngayo kunye neNkqubo yebhetri yakho
Iibhetri zesola azisebenzi zodwa{0}ziyinxalenye yesixokelelwano esihlanganisiweyo esilawula ukuhamba kwamandla phakathi kweepaneli zakho, ikhaya, ibhetri, kunye negridi yombane. Ubumbeko olukhethayo luchaphazela kakhulu impumelelo kunye nokusebenza.
Zimbini iindlela zokudityaniswa ezingundoqo ezikhoyo: AC-ezidityanisiweyo kunye ne-DC{1}}iinkqubo ezidityanisiweyo. Ngamnye uphatha umbane ngokwahlukileyo kwaye ulungele iimeko ezahlukeneyo.
Kulungiselelo lwe-AC{0} oludityanisiweyo, iiphaneli zesola zivelisa umbane we-DC othi kuqala udlule kwi-inverter yelanga, uwuguqulele kwi-AC ukuze isetyenziswe ekhaya. Ukuba ibhetri idinga ukutshajiswa, loo mandla e-AC emva koko aqukuqela ukuya kwi-inverter eyahlukileyo yebhetri eyiguqulela kwi-DC ukuze igcinwe. Xa ufuna amandla agciniweyo, i-inverter yebhetri iguqula i-DC ibuyele kwi-AC kwakhona. Le nguqulelo iphindiweyo inciphisa ukusebenza kakuhle kancinane-ngokwesiqhelo ngo-5-8%-kodwa inika ububhetyebhetye. Unokongeza iibhetri kwiinkqubo ezikhoyo zelanga ngaphandle kokutshintsha izixhobo, kwaye ibhetri inokuhlawula ukusuka kwiipaneli zelanga okanye amandla egridi.
DC-iinkqubo ezidityanisiweyo zithatha indlela ethe ngqo. Iphaneli yelanga ye-DC iphuma ngokuthe ngqo kwi-inverter edibeneyo elawula zombini uguqulo lwelanga kunye nokutshaja ibhetri. Umbane uguquka kube kanye kuphela-ukusuka kwi-DC ukuya kwi-AC xa kufuneka kusetyenziswe ekhaya. Le nguqulelo inye iphucula ukusebenza kakuhle nge-4-6% xa kuthelekiswa nodibaniso lwe-AC. Nangona kunjalo, iinkqubo ezidityanisiweyo ze-DC zifuna ii-inverters ezihambelanayo ze-hybrid kwaye zisebenza kakuhle xa ziyilwe kunye kwasekuqaleni.
Ukukhetha phakathi kwe-AC kunye ne-DC yokudibanisa kuxhomekeke kwimeko yakho. Ukuba wongeza ugcino kuluhlu olukhoyo lwelanga, ukudityaniswa kwe-AC kuyavakala. Kufakelo olutsha, udibaniso lweDC lubonelela ngobuchule obungcono. Abanye abaninimzi basebenzisa zombini-ukugcina i-solar esele ikhona kwi-AC ngelixa besongeza iiphaneli ezintsha ze-DC{4}}ezidityaniswe ukwandisa izibonelelo.
Ulawulo lokuhamba kwamandla luphathwa ngokuzenzekelayo. Ngeeyure zasemini ezinelanga xa iiphaneli zivelisa umbane omninzi kunowokusetyenziswa kwekhaya lakho, okugqithisileyo kuhlawulisa ibhetri yakho. Nje ukuba ibhetri ifikelele kumthamo opheleleyo, amandla angaphezulu athunyelwa ngaphandle kwigridi (ukuba i-net metering ikhona) okanye inkqubo inokunciphisa imveliso. Njengoko kusondela ukuhlwa kunye nokwehla kokuveliswa kwamandla elanga, ibhetri ithatha indawo ngaphandle komthungo, ikhupha amandla agciniweyo ukugcina umbane. Olu tshintsho lwenzeka ngokuzenzekelayo kwimizuzu emilise
Iisistim zala maxesha ziquka abalawuli abakrelekrele abalungiselela ixesha lokubiza, ukukhutshwa, okanye igridi{0}}ukuthumela ngaphandle ngokusekelwe kumaxabiso ombane, uqikelelo lwemozulu, kunye neepateni zakho zosetyenziso. Ukuba ukwixesha-lo{3}}lokusebenzisa amaxabiso, isilawuli sinokubeka phambili ukusetyenziswa kwebhetri ngeeyure eziduru kakhulu ngelixa sitsala ngexabiso eliphantsi{4}}lokusebenzisa amandla egridi encopho yokuzalisa naziphi na izikhewu.
Ikhemistri yebhetri kunye neempawu zokuSebenza
Ayizizo zonke iibhetri zokugcina amandla elanga asebenza ngokulinganayo. I-chemistry ethile ngaphakathi imisela umthamo, ubomi, ukhuseleko, kunye neendleko-ezisebenzayo.
I-Lithium iron phosphate (LiFePO4 okanye i-LFP) iibhetri zilawula indawo yokuhlala yelanga ngenxa yezizathu ezifanelekileyo. Zinika uzinzo olukhethekileyo lwe-thermal{2}}oluncinci kakhulu ukuba lube nobushushu obugqithisileyo xa kuthelekiswa nezinye iikhemistri ze-lithium. Ibhetri ye-LFP inokusebenza ngokukhuselekileyo kumaqondo obushushu ukusuka kwi--4℃F ukuya kwi-140℃F ngaphandle kokuthotywa kokusebenza okanye iingozi zokhuseleko. Ikhemistri ikwanika amandla imijikelo enzulu yokukhupha ngaphandle kokonakalisa iiseli.
Ubunzulu bokukhutshwa (i-DoD) bubhekiselele kubungakanani bomthamo webhetri uwonke onokuwusebenzisa ngokukhuselekileyo. Iibhetri ze-LFP zikholisa ukuxhasa i-80-100% DoD, okuthetha ukuba ibhetri ye-10 kWh ibonelela nge-8-10 kWh yamandla asebenzisekayo. Thelekisa oku kwiibhetri ezidala ze-lead-asidi ezikhawulelwe kwi-50% ye-DoD-kwaloo mthamo we-10 kWh unokubonelela kuphela nge-5 kWh yamandla asebenzisekayo.
I-DoD ichaphazela ngqo ubomi bomjikelo{0}}inani lentlawulo{1}}lokukhupha imijikelo phambi kokuba umthamo wehle kakhulu. Iibhetri ze-LFP ezithelekelwe kumjikelo we-6,000 kwi-80% ye-DoD zinokuzisa kuphela imijikelo engama-4,000 ukuba zikhutshwa rhoqo ukuya kwi-100%. Uninzi lwabavelisi bayila iinkqubo zabo ukukhusela ubomi obude ngokunciphisa i-DoD ukuya kwi-90-95% nangona ngokobuchwepheshe bekwazi ukwenza okungakumbi.
I-2025 Enphase IQ Battery 5P, umzekelo, isebenzisa iiseli ze-LFP ezilinganiswe kwimijikelezo ye-10,000 kwi-90% ye-DoD. Phantsi kwesiqhelo sebhayisekile yemihla ngemihla, oko kuguqulela kwiminyaka engama-25-30 yobomi benkonzo. Isixokelelwano solawulo lwebhetri sinyanzelisa umda wokukhupha ngokuzenzekelayo, ukuthintela abasebenzisi ukuba banciphise ubomi babo ngengozi.
Iibhetri ze-nickel manganese cobalt (NMC) zinika uxinano oluphezulu lwamandla{0}zipakisha ugcino oluninzi kwindawo encinci kunye nobunzima. Oku kubenza bathandeke apho indawo ixinzelelwe. Nangona kunjalo, ikhemistri ye-NMC ayizinzi kangako ngokwe-thermal, ifuna iinkqubo zokupholisa eziphucukileyo. Iibhetri ze-NMC nazo zinexesha elifutshane lokuphila, ngokuqhelekileyo i-3,000-5,000 imijikelezo kwi-80% ye-DoD.
I-Powerwall 2 kaTesla, esebenzisa ikhemistri ye-NMC, ibonelela nge-13.5 kWh eludongeni oludityanisiweyo{2}}iyunithi exhonyiweyo. I-Powerwall 3, ekhutshwe ngo-2024, yatshintshelwa kwikhemikhali ye-LFP yokhuseleko oluphuculweyo kunye nobomi obude, nangona inxinano yamandla encitshiswe kancinane.
Ubushushu buchaphazela kakhulu ukusebenza kwazo zonke iibhetri ze-lithium{0}}ze-ion. Amaqondo obushushu abandayo acothisa ukusabela kweekhemikhali, ukunciphisa umthamo okhoyo kunye nesantya sokutshaja. Ibhetri eku-32℃F inokubonelela kuphela ngama-70-80% omthamo wayo okalwayo. Amaqondo obushushu aphezulu akhawulezisa ukuthotywa{10}}ukusebenza ngokuqhubekayo ngaphezu kwe-95℃F kunokunciphisa ubomi bubonke ngama-20-30%. Yiyo loo nto uninzi lofakelo lwangaphandle lubandakanya iindawo ezivaliweyo ezilawulwa ngamaqondo obushushu.
-amazinga okuzikhupha abonisa ukuba amandla agciniweyo aphela ngokukhawuleza kangakanani xa engasetyenziswa. Iibhetri ze-LFP zilahlekelwa malunga ne-1-3% yentlawulo ngenyanga xa ingasebenzi, ingcono kakhulu kune-20-30% yelahleko yenyanga kwiibhetri ze-asidi. Oku kwenza i-lithium-ion ilungele amandla ogcino anokuhlala engasetyenziswa iinyanga.
IiNkqubo zoLawulo lwebhetri kunye neMiba yoKhuseleko
Yonke ibhetri yogcino lwamandla elanga inekhompyutha ephucukileyo ebizwa ngokuba yiBattery Management System (BMS) esebenza njengomgcini kunye nesilungisi. Ngaphandle kwayo, iibhetri ze-lithium -zinokuthembeka kwaye zibe nobungozi.
I-BMS isoloko ibeka iliso kwiiparamitha ezininzi kwiseli nganye ekwipakethi yebhetri. Ilandelela amandla ombane weseli nganye, iqinisekisa ukuba ahlala phakathi koluhlu olukhuselekileyo{1}}kakhulu kwi-2.5 ukuya kwi-3.65 yevolthi ngeseli nganye ye-LFP chemistry. Ukuba nayiphi na iseli ikhukuliseka ngaphandle kwale mida, i-BMS inciphisa ngokukhawuleza ukutshaja okanye ukukhupha umsinga, okanye iyivale ibhetri xa kuyimfuneko.
Ukujongwa kweqondo lobushushu kwenzeka kwiindawo ezininzi kwibhetri yonke. Abenzi boluvo be-Thermal babona iindawo ezishushu ezinokubonisa iibhulukhwe ezimfutshane zangaphakathi okanye iiseli ezingaphumeleliyo. Ukuba amaqondo obushushu angaphezulu kwemithamo ekhuselekileyo{2}idla ngokumalunga ne-140℃F kwibhetri ye-LFP{4}}i-BMS ivula iinkqubo zokupholisa okanye ikhuphe ibhetri kwisekethi.
Unyino lwangoku lukhusela kumazinga okutsalwa ngokugqithisileyo anokonakalisa iiseli okanye adale umngcipheko womlilo. Ikhemistri yebhetri nganye inokhuseleko oluphezulu lwentlawulo kunye namazinga okukhupha, alinganiswa nge-C{1}}yereyithi. Ibhetri ye-10 kWh enezinga lokukhupha i-1C inokubonelela ngokukhuselekileyo i-10 kW yamandla aqhubekayo. I-BMS inyanzelisa le mida kungakhathaliseki ukuba yimfuneko kangakanani na, yiyo loo nto iibhetri zinereyithingi "eqhubekayo yamandla" kunye "nepeak power".
Ulungelelwaniso lweseli ngomnye wemisebenzi ebalulekileyo yexesha elide ye-BMS-. Njengoko iibhetri zikhula, iiseli zomntu ngamnye ziphuhlisa amandla ahlukeneyo kunye nokuchasana kwangaphakathi. Ngaphandle kokulungiswa, ezinye iiseli ziya kutshaja kakhulu ngelixa ezinye zintywila ngaphantsi kumjikelo ngamnye, oko kukhawulezisa ukuwohloka. I-BMS isebenza ngokulungelelanisa iiseli ngokusabalalisa kwakhona intlawulo{4}}nokusebenzisa amandla angaphezulu ukusuka kwiiseli ezigcweleyo njengobushushu (i-passive balancing) okanye ukudlulisela intlawulo ukusuka kokugcweleyo ukuya kwiiseli ezingenanto (i-bancing esebenzayo). Oku kugcina zonke iiseli zisebenza ngokuvumelanisa, ukwandisa ubomi bepakethi ngokubanzi.
I-State of charge (SoC) uqikelelo lunzima kakhulu kunokuba lubonakala. I-BMS ayikwazi ukulinganisa ngokuthe ngqo ukuba angakanani amandla aseleyo{1}}endaweni yoko, ibala i-SoC ngokudibanisa ukuhamba kwangoku ngokuhamba kwexesha ngelixa ibala iziphumo zobushushu, iijiko zombane, kunye nedatha yokusebenza kwembali. Uqikelelo oluchanekileyo lwe-SoC lubalulekile ekuthinteleni ngaphezulu-ukukhutshwa, okunokonakalisa umphelo iiseli ze-lithium{4}}ze-ion.
Iiyunithi zale mihla ze-BMS ziquka iileya ezininzi zokuqhawula ukhuseleko. Ukuba isixokelelwano sibhaqa iimeko ezinobungozi-iimfutshane zangaphakathi, amaqondo obushushu agqithisileyo, amandla ombane angasebenziyo{2}}inokwenza iicontacts ezingoomatshini okanye{3}}iindawo ezikhuselweyo eziqinileyo ukuhlukanisa ngokwasemzimbeni ibhetri kuzo zonke iindibano. Ezinye iisistim zibandakanya iisekethe zokhuseleko ezingafunekiyo, ezifuna ukungaphumeleli okuzimeleyo okuphindaphindiweyo ngaphambi kokuba imeko eyingozi iphuhlise.
Iiprothokholi zonxibelelwano zivumela i-BMS ukuba yabelane ngedatha nee-inverters, izilawuli zentlawulo, kunye ne-apps yokubeka iliso. Unokubona{1}}ixesha lokwenyani lokuhamba kwamandla, i-SoC, ubushushu, kunye neemetrics zokusebenza ngeapps ze-smartphone. Okona kubaluleke kakhulu, isiguquli sisebenzisa idatha ye-BMS ukukhulisa iiparamitha zokutshaja{3}}ukulungisa amandla ombane kunye nangoku ukukhulisa impilo yebhetri ngelixa uhlangabezana neemfuno zamandla.
Ukuqwalaselwa kobungakanani kunye nomthamo
Ukukhetha ubungakanani bebhetri bokugcina amandla elanga kufuna ukuqonda iimfuno zakho zamandla kunye nendlela iibhetri eziphuma ngayo ekuhambeni kwexesha. Umthamo wodwa awuthethi ibali elipheleleyo.
Umthamo webhetri uthelekelelwa kwiikilowatt-iiyure (kWh), emele ugcino lwamandla ewonke. Ibhetri ye-10 kWh ngokwethiyori inokuhambisa i-10 kW ngeyure enye, i-5 kW iiyure ezimbini, okanye i-1 kW iiyure ezilishumi. Eyona nto iyinyani yahluke kakhulu. Umlinganiselo wamandla, olinganiswa ngeekilowatts (kW), ubonisa ukuba ibhetri inokuhambisa ngokukhawuleza kangakanani amandla. Ibhetri inokuba nomthamo we-10 kWh kodwa kuphela i-5 kW eqhubekayo yokuphuma kwamandla{11}}okuthetha ukuba kuthatha ubuncinane iiyure ezimbini ukukhupha ngokupheleleyo, nokuba ifuna ntoni na.
Oku kubalulekile xa ulinganisa amandla okugcina. I-backup-yonke yekhaya ngexesha lokucima ifuna ukugquma imithwalo ephezulu{2}}xa izixhobo zombane ezininzi eziphezulu{3}zisebenza ngaxeshanye. Ikhaya eliqhelekileyo elingama-2,000 onyawo lwesikwere ekhaya linokuba ne-30-40 amp amp main panel draw ngexesha lokusetyenziswa okuphezulu, ukuguqulela ku-7-10 kW. Ukuba ibhetri yakho ibonelela ngemveliso eqhubekayo eyi-5 kW kuphela, uya kufuna ulawulo lomthwalo okanye ipaneli yomthwalo obalulekileyo ukubeka phambili iisekethe ezibalulekileyo.
Iintsuku zokuzimela zigqiba ukuba ibhetri yakho idinga ixesha elingakanani ukugcina ikhaya lakho ngaphandle kokufakwa kwelanga. Olunye usuku lokuzimela luthetha ukulinganisa umndilili wosetyenziso lwakho lwemihla ngemihla. Uninzi lwabanikazi bezindlu bajonge 1-intsuku ezi-2 zegridi-ebotshiweyo kwiinkqubo, besazi ukuba ilanga lizakutshajwa kwakhona emini. Iinkqubo ezingaphandle kwegridi zidla ngobungakanani beentsuku ezi-3 ukuya kwezi-5 ukujongana namaxesha amafu awandisiweyo.
Bala iimfuno zakho ngokuphonononga ukusetyenziswa kombane wembali. Ikhaya elisebenzisa i-30 kWh yonke imihla liya kufuna amandla angama-30 kWh usuku olunye lokuzimela. Into ekwisakhono esisebenzisekayo{4}}khumbula ukuba 80-90% umda weDoD. Ibhetri ye-10 kWh ene-90% ye-DoD ibonelela nge-9 kWh esebenzisekayo. Kusetyenziso lwemihla ngemihla lwe-30 kWh, uya kudinga malunga ne-34 kWh yomthamo webhetri iyonke, kubalelwa kuma-90% alinganiselweyo anokusebenziseka.
Ukwahluka kwamaxesha kubalulekile. Ukusetyenziswa kwamandla ebusika kaninzi kudlula ihlobo kwiindawo ezibandayo ngenxa yemithwalo yokufudumeza kunye nokunciphisa imveliso yelanga. Ubungakanani beyona{2}}eyona meko imbi ngaphandle kokuba ukhululekile ngogcino lwegridi ngelo xesha.
Ukumodareyitha kuvumela ukwandiswa ngezigaba. Iinkqubo ezininzi zebhetri zikuvumela ukuba uqale ngeyunithi enye kwaye wongeze ezinye kamva. I-Enphase IQ Battery 5P, umzekelo, ibonelela nge-5 kWh ngeyunithi nganye kunye nezikali ukuya kuma-40 kWh (iiyunithi ezisibhozo) njengoko iimfuno zikhula. Le ndlela isasaza iindleko ngelixa uphepha ukugqithisa ekuqaleni.
Ukutshintshwa komthwalo ngexesha-lo-lokusebenzisa (TOU) usetyenziso lwezinga lokuphucula lufuna ingqiqo yobungakanani obahlukileyo. Endaweni yeentsuku zokuzimela, bala ukuba ingakanani na incopho- yosetyenziso lweyure ofuna ukuyigubungela ngesolar egciniweyo. Ukuba ikhaya lakho lisebenzisa i-5 kWh phakathi kuka-4-9 PM nge-$0.35/kWh, kodwa amandla angekho phezulu axabisa i-$0.12/kWh, ibhetri eyi-5 kWh inokonga malunga ne-$35 ngenyanga ngokusebenzisa isola egciniweyo endaweni yamandla abiza kakhulu. Iindleko zebhetri zokonga ngokuhamba kwexesha, nangona amaxesha okubuyisela ahluka kakhulu ngendawo kunye nokwakhiwa kwereyithi.
