kW i go long kWh Kalkuleta: Save long Pawa na Eneji
Wanpela menesa bilong baim ol samting long wanpela kol stoa long Michigan i bin ringim mipela long las mun. Em i laik senisim olpela lid-asid forklift bateri bilong em wantaim ol litiam yunit, na em i pinisim homwok bilong em. Kain olsem. Em i skelim olsem ol 'forklift' bilong em i save yusim samting olsem 4kW long averes, ran 6-pela aua long wanwan wok, olsem na em i nidim 24kWh bateri. Simpol multiplikasen.
Tasol ol 'forklift' bilong em i no wok long ful sif moa. Bihain long mipela i lukluk long ol 'operational data' bilong em, 'real requirement' i kamap klostu long 38kWh. Dispela spes i no wanpela asua bilong matematiks. Em i kliagut long kW na kWh gut tru. Samting em i lusim em ol lus bilong 'efficiency', 'depth of discharge limits', na 'capacity degradation' bilong wok insait long -5 digri envairomen. Ol dispela samting i no save kamap long ol besik kalkuleta, na ol i no save kamap long planti ol saplaia kwotesen tu.
Pawa Dro vs. Eneji Stoa
Difrens namel long kilowatt na kilowatt-aua i save mekim ol saveman bilong baim ol samting i go antap, moa yet bikos ol dispela tok i save senis senis inap long taim yu stat long raitim ol oda bilong baim ol samting.
Kilowatts i save skelim pawa we i save kamap hariap. Taim 'forklift motor' bilong yu i ron long 8kW, dispela em i mak we em i save kisim pawa long en long wanem taim. Kilowatt-aua i skelim olgeta pawa we ol i yusim long taim. Wanpela 8kW mota we i wok long 2-pela aua i save yusim 16kWh bilong pawa.
Fomula bilong senisim em i isi tru:
Eneji (kWh)=Pawa (kW) × Taim (aua)
Tasol dispela fomula i kisim ol gutpela kondisen. Ol trupela bateri i no save wok olsem.
Ol Namba we Saplaia bilong yu i no soim yu
Ol datasit bilong bateri i listim liklik kapasiti. Wanpela "100kWh" bateri pek i gat 100kWh bilong 'theoretical energy storage'. Yusim kapasiti i narapela, planti taim em i stap klostu long 80% bilong ol litiam sistem. Ol bateri menesmen sistem i save holim 20% bilong olgeta kapasiti bilong stopim ol dip 'discharge cycles' we i save mekim bagarap hariap.
| Spesifikasen Taip | Mining bilong en | Tipikel veliu |
|---|---|---|
| Nominal Kapasiti | Total theoretical storage | 100 kWh |
| Yusim Kapasiti | Eneji i stap pastaim long BMS i pinis | 80 kWh |
| Gutpela Raun-trip | Eneji i go aut ÷ Eneji i kam insait | 87-94% |
| Dip bilong Discharge (DoD) | Rekomended discharge pesen | 80% bilong LFP |
Tempereja i mekim hevi i go bikpela moa. Folem tes data bilong DOE, litiam bateri kapasiti i go daun long samting olsem 80% long 0 digri na i pundaun aninit long 60% long -20 digri. Dispela Michigan fasiliti i save ranim ol 'forklift' insait long ol haus kago we i gat aisbokis? Ol "100kWh" bateri bilong em i save givim ating 65kWh bilong eneji we ol i ken yusim long taim bilong kol.
Stret fomula bilong sais i makim ol dispela samting:
Bateri Kapasiti=(Lod Pawa × Rantaim × 1.1 sefti fakta) ÷ DoD ÷ Efisiensi
Long wanpela 5kW lod we i ran 4-pela aua: (5 × 4 × 1.1) ÷ 0.8 ÷ 0.92 = 29.9 kWh
Nogat 20kWh. Difrens namel long dispela tupela namba em i difrens namel long ol bateri we i save pinisim wok gut na ol bateri we i save pasim ol opereta namel long -aisle long 2 klok apinun.
C-Reit na Bilong wanem Sais bilong Bateri i Afektim Moa Long Runtaim
Ol lain bilong baim ol samting i save askim mipela sapos ol i mas baim wanpela bikpela bateri o planti liklik bateri. Ansa i dipen long hau yu plen long yusim ol, na dispela i bringim yumi i go long C-reit.
C-reit i tok klia long spit bilong 'discharge' we i go long 'capacity'. Wanpela 1C discharge i save rausim wara long bateri insait long wanpela aua. Wanpela 0.5C discharge i save kisim tupela aua. Wanpela 2C discharge i save kisim tripela ten minit.
Ol bikpela C-reit i save kamapim moa hat insait long ol sel bilong bateri. Moa hat i min olsem wok i no wok gut, bagarap i kamap hariap, na long ol bikpela hevi, ol samting bilong lukautim hat we i save putim bikpela pe na hevi.
| C-Reit | Taim bilong lusim haus sik | Gutpela wok | Kamapim Hat |
|---|---|---|---|
| 0.5C | 2 aua | 96-98% | Daunbilo |
| 1C | 1 aua | 93-95% | I no bikpela |
| 2C | 30 minit | 88-92% | Hai |
| 3C+ | <20 minutes | <88% | I nidim 'active cooling' |
Dispela em i hap we kW-long-kWh rilesensip i kamap gutpela long ol disisen bilong baim ol samting.
Tingim tupela samting we inap kamap long wanpela 'forklift' we i gat 12kW:
Opsen A: 20kWh bateri pek
Bikpela diman i save kamapim 0.6C 'discharge rate'. Gutpela wok i stap klostu long 94%. Nogat moa kol i mas kamap. Tasol taim bilong wok i no inap long 3-pela aua bilong wok tru.
Opsen B: 40kWh bateri pek
Wankain 12kW mak i kamapim 0.3C discharge rate tasol. Wok bilong wok i go antap long 97%. Taim bilong ran i go inap long 6+ aua. Bateri i no save kisim planti hevi long olgeta taim, na dispela i save mekim laip bilong en i stap longpela taim moa.
Bikpela pek i gat bikpela pe pastaim. Tasol ol gutpela wok i kamap bikpela moa long planti tausen taim bilong sasim, na laipspan i go longpela i save daunim kos bilong senisim. Mipela i bin ranim ol namba long planti 'fleet' konvesen, na 'breakeven point' i save pundaun long 18-24 mun long ol operesen we i save ranim planti 'shift'.
Lithium vs. Lead-Acid: Skelim bilong inap bilong olgeta manmeri i save rong
Planti skelim bilong ol bateri i save lukluk long kemistri. Lithium i save stap longpela taim, i save sasim hariap, na i no nidim planti wok mentenens. Olgeta i tru. Tasol skelim bilong kapasiti em we ol tim bilong kisim ol samting i save mekim ol bikpela rong.
Wanpela 100Ah lid-asid bateri we i gat mak bilong C20 (20-aua 'discharge') i save givim liklik pawa tru aninit long ol gutpela wok kondisen. Dispela samting, ol i kolim Peukert effect, i save mekim ol 'lead-acid' bateri i lusim 30-50% bilong 'rated capacity' bilong ol taim ol i rausim hariap.
| Kain Bateri | Peukert Exponent | Kapasiti long 1-aua discharge | Gutpela Lus |
|---|---|---|---|
| Lithium (LFP) | 1.02-1.10 | 95-98 Ah | 2-5% |
| AGM Lead-Acid | 1.05-1.15 | 80-90 Ah | 10-20% |
| Flooded Lead-Acid | 1.20-1.60 | 50-70 Ah | 30-50% |
Wanpela "100Ah" 'lead-asid bateri we i pulap long en na em i 'discharge' insait long wanpela aua em inap long givim 56Ah tasol. Wanpela "100Ah" litiam bateri aninit long wankain kondisen i save givim 95-98Ah.
Dispela i eksplenim as na ol 'fleet operators' we i senisim 'lead-acid' i go long 'lithium' i save painim olsem ol liklik '-'kapasiti 'lithium' pek i winim ol bikpela 'lead-asid bipo. Ol namba bilong 'nameplate' i no wankain bikos ol 'underlying technologies' i save wok long narapela kain taim aninit long 'load'.
