Ku pulojekiti-level deployment, LFP ye kemiko esinga okubuna yaffeenkola z'okutereka LiFePO4 eza vvulovumenti enkulu-nekabineti ey’ebweru BESSlayini z’ebintu, kubanga obulamu bw’enzirukanya n’emiwendo gy’obukuumi bituukana n’obukwakkulizo bwa ggaranti abaguzi b’ebyobusuubuzi bwe baagala.

Battery ya Lithium-Ion eya bulijjo kye ki?

"Lithium-ion eya bulijjo" mu nkozesa y'amakolero etera okutegeeza:

• LCO - lithium cobalt oxide, etera okubeera mu byuma ebikozesebwa mu byuma bikalimagezi
• NMC - lithium nickel manganese cobalt oxide, ekozesebwa nnyo mu paaka za EV n’enkola ezimu eziyimiridde
• NCA - lithium nickel cobalt aluminium oxide, ekozesebwa mu nkola za EV ezirondeddwa
• LMO - lithium manganese oxide, etera okutabulwa ne NMC

Kemiko zino zikola ku vvulovumenti ey’erinnya esingako (mu ngeri entuufu V 3.6 ku 3.7) era ziweereza amaanyi ag’enjawulo aga waggulu, y’ensonga lwaki zisigala nga ze zisookerwako ku masimu, laptop, drones, ebikozesebwa mu masannyalaze n’emmotoka nnyingi ez’amasannyalaze. Ku kutereka okutambula, NMC oluusi n’oluusi elondebwa ng’ekifo kikugirwa, naye eby’ebbugumu-enkula y’okudduka n’okusuubulagana kw’obulamu bw’enzirukanya{4}}byetaaga okukolebwako ku ddaala ly’enkola.

LiFePO4 vs Lithium-Ion: Oludda-ku-Okugeraageranya Oludda

Emiwendo gino gya ranges eziraga. Enkola y'ensi entuufu-esinziira ku ddaala ly'obutoffaali, ensengeka ya pack, enzikiriziganya ya BMS n'embeera y'emirimu; datasheets z’abakola zisigala nga ze zijuliziddwa obuyinza ku kintu kyonna ekigere.

Obukuumi n’okutebenkera mu bbugumu

Obutoffaali bwa LFP bulina ebbugumu ery’okutandika ery’ebbugumu-erya waggulu okusinga obutoffaali bwa NMC oba NCA, era amasoboza agafulumizibwa mu kiseera ky’okudduka okutwalira awamu gaba wansi. Okunoonyereza okwafulumizibwa Oak Ridge National Laboratory nga kugeraageranya obutoffaali obunene-format lithium-ion wansi w’okukozesa obubi okusasula okusukkiridde kwazuula nti obutoffaali bwa LFP bwalaga okuddamu okw’ebbugumu okutono okusinga obutoffaali bwa NCM, obuwerako ku bwo bwakuma omuliro oba ne bufulumya empewo ey’amaanyi nga bugezesebwa. Kino tekifuula LFP "safe by default": kemiko yonna eya lithium esobola okulemererwa singa eyonoonese ebyuma, obuzibu mu kukola, okusasulwa okusukkiridde oba ensengeka za BMS ezitali ntuufu.

Ku nkola eziyimiridde, omulimu gw’obukuumi gusalibwawo nnyo okusinziira ku kugatta nga bwe gusalibwawo kemiko. Pack{1}}level fire performance, cell-to-cell okusaasaana, okuzuula ggaasi, okuziyiza omuliro n'okugereka enclosure byonna bitwala obuzito obw'amaanyi.Satifikeeti ya UL eri BESS(okugeza UL 9540 ne UL 9540A) ne IEC 62619 okugezesa kuwa enkola ey’omugaso ennyo ey’okugeraageranya okusinga ebiwandiiko bya kemiko byokka.

Obulamu bw’enzirukanya: Engeri y’okusomamu ennamba

"Obulamu bw'enzirukanya" ye nsonga emu esinga okusomebwa obubi mu datasheets za bbaatule. Ekipimo kya "6,000 cycle" kiba kya makulu nga kisomeddwa wamu ne:

• Obuziba bw’okufulumya (okugeza. 80% DoD, 90% DoD, 100% DoD)
• Ebbugumu ly’ekifo oba ery’obutoffaali mu kiseera ky’okuvuga obugaali
• Okusasula n'okufulumya C-omuwendo
• Enkomerero-ya-omusingi gw'okukuuma obusobozi bw'obulamu (ebiseera ebisinga 80% oba 70%)
• Emyaka gya kalenda mu kiseera ky’okugezesebwa

Ku nkola ya home backup evuganyizibwa buli lunaku, saba obulamu bwa cycle ku 80% DoD ne 25℃nga capacity retention eri 80%, so si nnamba y’omutwe. Ku pulojekiti y’okusenya ey’oku ntikko-edduka enzirukanya eziwera buli lunaku, metric ekwatagana efulumizibwa mu MWh eweebwa mu kiseera kya ggaranti.

Densite y’amasoboza n’obuzito

Kino kye kitundu lithium-ion eya bulijjo mw’ekyawangula mu ngeri esalawo. Obutoffaali bwa NMC ne NCA butereka amaanyi mangi buli kkiro ne buli liita, y’ensonga lwaki bufuga ebyuma ebikozesebwa mu byuma bikalimagezi, ennyonyi ezitali za bulijjo (Drones) ne EVs ng’obuzito bukosa butereevu omulimu. LFP packs zizitowa era nnene ku busobozi bwe bumu obukozesebwa, ekitatera kuba kikulu mu kabineti essiddwa ku rack- naye nga kikulu nnyo mu quadcopter.

Okulabula kumu: ku ddaala lya pack, ekituli kikendeera. Enneeyisa ya LFP ennungi ey’ebbugumu esobozesa ebanga erinywevu mu butoffaali n’okukendeeza ku byuma ebiddukanya ebbugumu-mu nkola nnyingi ezitakyukakyuka, ekiziyiza ekitundu ekizibu ky’obuziba bw’omutendera gw’obutoffaali-.

Enneeyisa y’okusasula n’okukwatagana kw’enkola

LFP ne lithium-ion eya bulijjo teziyinza kugabana profile y’okucaajinga y’emu. Amadirisa ga vvulovumenti, taper logic n’obukodyo bw’okutebenkeza byawukana, era okukozesa profile enkyamu kikendeeza ku bulamu era kireeta akabi k’obukuumi. Nga tonnaba kukyusa kemiko emu n’ossaamu endala, kakasa nti:

• Paka vvulovumenti ya chajingi emanyiddwa n'ejjuvu- (okugeza. 51.2 V LFP vs 48 V "lithium" labelling)
• Voltage y’okucaajinga esinga obunene n’enneeyisa y’okulengejja
• Solar charge controller oba PCS firmware okukwatagana
• Inverter low-voltage esala-era era eddamu-okuyunga thresholds
• Enkola y’empuliziganya ya BMS (CAN, RS485, Modbus) n’obuyambi bwa inverter obukwatagana
• Omukozi-olukalala lw'okukwatagana olukkiriziddwa

Battery bbiri eziwandiikiddwako "lithium" tezikyusibwakyusibwa. Kino kye kimu ku bisinga okulemererwa mu nnimiro mu pulojekiti z’okuddaabiriza.

Enkola y'ebbugumu n'okucaajinga ebbugumu erya wansi-

Okucaajinga bbaatule yonna eya lithium wansi wa diguli 0 kiteeka mu bulabe bw’okussaako lithium ku anode, ekikendeeza ku busobozi enkalakkalira era kiyinza okukosa obukuumi. LFP tesonyiyibwa mu kino. Ebigonjoola ebikola oba okubuguma okukola okuzimbibwa mu pack oba BMS-enforced charge cut-off wansi w’ebbugumu ery’omusingi. Okufuluma ku bbugumu eri wansi okutwalira awamu kugumiikiriza mu bugazi, wadde ng’obusobozi obuliwo bukendeera.

Ku kabineti ez’ebweru eziteekebwa mu mbeera ennyogovu, ebiragiro ebisaanira okukeberebwa mulimu wattage ya hhuta, ebbugumu erikkirizibwa okucaajinga, n’okumanya oba ebbugumu liweebwa amaanyi okuva mu pack yennyini oba okuva mu auxiliary supply ey’enjawulo. Okuwandiika kwaffe mu bujjuvu-kuebbugumu lya bbaatule ya lithiumebikka ku madirisa agakola agakozesebwa mu bifo eby’obusuubuzi.

Okugeraageranya Ebisale

Lithium-ion eya bulijjo etera okulabika nga ya buseere ku bbaluwa y’ebintu, naye okugeraageranya kuno tekutera kukwata ku ddaala ly’ensengekera. Ebivuga omuwendo gwonna mulimu emiwendo gy’obutoffaali, obuzibu bwa BMS, ebikozesebwa mu kuddukanya ebbugumu-, okuzibikira, okukakasa, embeera za ggaranti, obulamu bw’enzirukanya obusuubirwa n’enteekateeka y’okukyusa. Ku pulojekiti etambula buli lunaku mu myaka kkumi, pack ya LFP eya waggulu-upfront etera okutuusa omuwendo omutono ku buli kWh ewereddwa okusinga pack ya NMC eya layisi eyeetaaga okukyusibwa nga bukyali.

Ttiimu z’okugula zirina okusaba omuwendo ku buli cycle ekozesebwa n’omuwendo ku buli kWh ewereddwa ey’okuyita, so si $/kWh zokka ez’obusobozi bw’ekipande ky’erinnya.

Okukozesa-Obulagirizi obwenjawulo

Jenereta z’amasannyalaze g’enjuba n’amabibiro g’amasannyalaze agayitibwa Portable Power Station

LFP efuga ekika kino olw’ensonga ze zimu z’efuga okutereka okutakyuka: obulamu obuwanvu obw’enzirukanya n’enneeyisa y’ebbugumu ennywevu. Enkyusa za NMC zikyaliwo ng’obuzito obutono bwe butunda, naye akatale okusinga kakyuse ne kadda ku LFP.

Okutereka amaka g'okusulamu n'okuggyako-Grid Solar

LFP ye nkola esookerwako. Ku nkola ya 48 V oba 51.2 V home backup system eyategekebwa okuvuga obugaali buli lunaku, okugeraageranya okukwatagana kuli wakati wa LFP packs ez’ebika by’obutoffaali eby’enjawulo, omutindo gwa BMS n’okukwatagana kwa inverter - si wakati wa LFP ne NMC.

Okutereka amaanyi mu by’obusuubuzi n’amakolero

LFP ye kemiko eya mutindo mu mulembeokutereka amaanyi mu by’obusuubuzi n’amakolerookuteekebwa mu nkola. Ku minzaani eno, kemiko yokka tesalawo bivaamu; enzimba ya pack, okuddukanya ebbugumu, omuliro-safety design n'okuweebwa satifikeeti bitwala obuzito obusingako. Ekiwandiiko kyaffe ekijuliziddwa kuebitundu bya BESS ebikuluekwata ku nkola entonotono ezivuga ddala okwesigamizibwa okw'ekiseera ekiwanvu-.
