Long ol longwe ples long Maluku, Palawan na Sabah, disel we ol i salim i ken kost planti taim moa long prais bilong pam. Taim ol i inkludim trenspot, hanling, lus, stil na mentenens bilong jenereta, kos bilong wan wan kWh bilong lod ol i givim long wan wan yia i kamapim wanpela bekim we i no klia tumas — na i soim stret we 'lead-carbon' na 'lithium' i win.

Wanpela Diesel Genset i kost tru long wanpela ailan

Ol longwe ples long Maluku, Papua na Sulawesi ausait ailan bilong Indonesia, long Palawan na Mindanao hailans bilong Filipins, na insait long Sabah na Sarawak i gat wankain samting: grid i no stap o i save kamap inap sampela aua tasol long wanpela de. Bekap long ol dispela hap em i no bekap nating — em i namba wan saplai, na disel jenereta i save ron 8-pela i go inap 20 aua long wanpela de. Long dispela taim prais bilong wanpela bateri string i no bikpela samting; wanem samting i bikpela samting em kos bilong wan wan kWh bilong lod ol i save sevim long wan wan yia. Kost bilong disel we ol i salim i gat 5-pela samting: prais bilong pam, kago i go long jeti, namba tu lek trenspot long jeti i go long ples (bot, motobaik, man i save karim), ol lus bilong stoa na stil, na mentenens na ovahol bilong jenereta we ol i rausim long aua bilong ran. Long ol ples maunten we i nidim 'porterage', namba tu lek tasol inap long wanpela o tupela taim prais bilong bensin; putim sevis long olgeta 500 aua na stretim long olgeta 5,000 aua na rot bilong disel i save kost tupela o foapela taim moa long disel jeneresen bilong taun long wan wan kWh. Na dispela namba i save muv wantaim prais bilong bensin na 'logistics capacity' - ol samting we i no gat opereta i bosim.

Senisim prais bilong bateri i go long kos bilong wan wan kWh-Yia

Ol skelim bilong ol bateri i no gat mining sapos ol i no senisim i go long wanpela komon beis. Stretpela kalkulesen i bungim prais bilong baim, namba bilong ol senis long sevis laip, trenspot na wokman bilong wanwan senis, na eneji kos bilong ol lus bilong sasim/discharge, na bihain brukim long reit kapasiti × yusebol dip bilong discharge × yia bilong ron long baisikol, na givim kos long wan wan kWh-yia. Kisim wanpela 48V/100Ah string we i gat mak bilong 4.8 kWh: long 50% dip bilong 'discharge' 2.4 kWh tasol inap long yusim, na long wanpela deili saikel dispela 2.4 kWh i mas karim 365 de. Sapos ol i senisim string long olgeta tripela yia, olgeta tripela baim i ken kamap — i no namba wan tasol. Dispela wanpela step i soim tupela komon asua: tingim 'rated capacity' olsem 'usable capacity', na tingim 'design life' olsem 'cycle life'. Aninit long 'dely cycling', wanpela bateri we i gat mak bilong 12-pela yia bilong 'float service' inap long givim 300 i go inap 500 'cycles' tasol - pinis insait long wanpela yia.

Bilong wanem Lead-Carbon i gutpela long ron long baisikol long olgeta de

Aninit long wanpela 'charge-discharge cycle' long wanpela de wantaim longpela taim long 'partial state of charge', nomol AGM i save feil hariap: 'negative plate' i save 'sulphate' hariap insait long PSoC, na kamapim ol 'dense lead sulphate crystals' we nomol 'charge voltage' i no inap long daunim, olsem na kapasiti i save lus olgeta. Lead-carbon i save stretim dispela hevi stret long rot bilong putim 'activated carbon' long 'negative plate', na kamapim wanpela 'combined capacitive' na 'electrochemical storage mechanism' olsem na 'charge current' i save kisim 'capacitive path' na 'sulphate' i no save kamap antap long 'plate surface'. LLC series (300-1,000Ah, 6-pela model, 2V) i yusim 'lead-carbon capacitance' teknoloji wantaim 4-pela i go inap 5-pela taim 'cycle life' bilong ol konvensenel prodak insait long PSoC diuti, klostu 30% gutpela 'charge acceptance', na 20-yia disain laip. Long ol ailan sait, 30% hariap 'charging' i ken bikpela samting moa long 'cycle life': jenereta i save ron sampela aua tasol long wanpela de, 'charging window' i sotpela, na 'charge acceptance' i makim hamas eneji ol i kisim bek long olgeta de — na long dispela as sapos sait i stap inap long neks jenereting taim.

Taim Lithium Em i Stretpela Ansa

Lithium em i no wanpela 'lead-carbon' we ol i bin apgredim; em i narapela kain aplikebiliti baundri. Ol 48V LiFePO4 sistem (SDA10 series, 50-200Ah, foapela model) i save givim 1C 'discharge' na longpela 'cycle life' long wanpela hap bilong volium na hevi bilong wankain 'lead-acid capacity'. Tripela samting i save helpim 'lithium': ol hap we i no gat planti spes o plua, olsem ol liklik kebinet we ol i putim antap long wanpela taua we 'lead-acid' i no inap long go insait long en; ol aplikesen we i nidim bikpela 'instantaneous current', we 1C i min olsem wanpela 100Ah string inap long givim 100A oltaim, we 'lead-acid' i no inap long mekim long wankain volium; na ol sait we i gat sevis laip moa long 10-pela yia na bikpela kos bilong trenspot, we bikpela kos bilong namba wan i kamap long tupela samting we ol i no senisim. Long narapela sait, long ol hap we temperaja bilong ples i stap antap long 45°C na i no gat 'thermal management', laip bilong 'lithium' i save pinis hariap na 'lead-carbon's 'heat tolerance' i gutpela moa. Dispela tes i no long wanem teknoloji i moa advans, tasol wanem bilong tripela — tempereja profail, 'cycling frequency', kos bilong trenspot — em i dia tumas long dispela hap.

Tripela 'Hybrid Topologies'

Ol ailan sait klostu i no save ron long wanpela sos tasol, na 'topology' makim i save makim gutpela wok bilong en. Namba wan em disel-praimeri wantaim bateri bafa: jenereta i ran agensim lod na bateri i karamapim ol spes bilong senisim na pasim long nait. Kost bilong stretim ol samting i no antap tumas, em i gutpela long ol liklik kago we ol i ken yusim bensin saplai tasol grid i no stap olgeta. Namba tu em sola na bateri na disel 'standby': PV i save givim lod na sasim bateri long san, bateri i save lus long nait, na disel i save stat tasol bihain long klaut i stap longpela taim o bateri i pinis. Ol aua bilong disel i ken pundaun aninit long tupela aua long wanpela de wantaim bikpela seving bilong bensin, tasol em i nidim gutpela eria na das proteksen. Namba tri em i wanpela ful rinewabel sola na bateri na liklik win konfigurasen, we i ken wok tasol long hap we spit bilong win i stap gut na lod i liklik — we i no inap long mekim wok long Saut-is Esia monsun belt. Wanem samting olgeta tripela i wankain em olsem bateri i save muv long 'standby' i go long 'daily cycling prime mover', olsem na 'cycle life', 'charge acceptance' na 'high-tempereture behavior' i save makim sistem ekonomiks - i no jenereta efisiens.

Skelim sais bilong bateri insait long wanpela haibrid sistem

Bateri kapasiti insait long wanpela haibrid sistem i mas i go long longpela taim we i no gat 'recharge', na i no long 'backup hours' — na tupela bekim i ken i no wankain long tupela taim. Kalkulesen i gat foapela step. Namba wan, deili eneji konsumsen: lod long kW × 24 aua, luksave olsem de na nait lod i save senis na ol i mas skelim wanwan na bihain bungim. Namba tu, em i longpela taim tru we i gat klaut: tupela o tripela de insait long Saut-is Esia 'monsoon belt', we tripela de i no gat planti klaut; Ol hailans long Is Afrika i soim planti kain kain klaut, olsem na putim wanpela de. Namba tri, yusebol kapasiti rikwaemen = deili konsumsen × ol de we i gat klaut ÷ alawem dip bilong discharge, kisim DOD long 70%. Namba foa, yusim 'temperature' na 'aging correction', planti taim ×1.15 i go inap ×1.25. Long wanpela sait we i save yusim 24 kWh long wanpela de, tripela de bilong 'autonomy' long 70% DOD i nidim samting olsem 103 kWh yu ken yusim, o klostu 124 kWh bihain long 20% ​​stretim. Dispela namba i save bikpela moa long 'foa-aua bek-ap' kalkulesen i save kamapim, bikos tupela i bekim ol narapela narapela askim: wanpela em wanem samting long mekim taim san i no kamap inap long tripela de, narapela em wanem samting long mekim taim san i no wok inap long 4-pela aua. Long wanpela of-grid sait namba wan tasol i gat mining. Sapos yu no bikpela tumas na sistem bai pundaun long namba wan 'overcast spell' - planti taim long taim we ol toktok i bikpela samting; mekim i kamap bikpela tumas na pe bilong en i go inap long taim projek i no kamap gut long baset komiti. Kisim piksa bilong 'conservative ovakast'; noken katim kapasiti i go long tupela de long sevim mani. View Telecom Backup Power Selection
