En AC-blok er et fuldt integreret batterienergiopbevaringsprodukt, der samler batterimoduler, BMS, termisk styring og PCS (effektkonverteringssystem) i én enhed. I modsætning til DC-blokke, der kræver en ekstern konverter, leverer en AC-blok netkompatibel vekselstrøm direkte. For indkøbsteams forenkler denne alt-i-én-arkitektur systemintegrationen, reducerer antallet af leverandørrelationer og mindsker BoP-kompleksiteten.
AC-blokke bruges oftest i C&I-applikationer og mindre utility-scale-projekter, hvor enkelhed og hurtig idriftsættelse prioriteres. For store projekter giver separat indkøb af DC-blokke og PCS mere arkitektonisk fleksibilitet og bedre forhandlingspositioner.
Nøglespecifikationer
Hvad man bør sammenligne ved evaluering af AC-blokke
Ved udvælgelse af til et BESS-projekt er disse de vigtigste tekniske specifikationer, som EPC-virksomheder, projektudviklere og systemintegratorer typisk evaluerer:
C-rate
0,25C – 1C
Bestemmer den maksimale lade-/afladeffekt i forhold til kapaciteten. De fleste AC-blokke er designet til 0,5C og balancerer ydeevne og levetid.
Energikapacitet
215 kWh – 10 MWh
AC-blokke dækker et bredt spænd — fra C&I-enheder (215 kWh) til utility-scale-containere (10 MWh). Den optimale størrelse afhænger af applikation og systemarkitektur.
Kemi
LFP dominerende
LFP er standardkemien til AC-blokke på grund af sikkerhedsprofil og cykluslevetid. Nogle C&I-produkter anvender NMC, når højere energitæthed kræves.
Tur-retur-virkningsgrad
85 – 92 %
Virkningsgrad målt på AC-siden, inklusive PCS-tab. Typisk en smule lavere end separate DC-blok + PCS-systemer, da den integrerede PCS ikke altid opererer i sit optimale driftspunkt.
Kølemetode
Væske eller luft
Større utility-scale AC-blokke anvender i stigende grad væskekøling. Mindre C&I-enheder bruger typisk luftkøling.
Certificeringer
UL 9540A, IEC 62619
Samme basiscertificeringer som DC-blokke. Da AC-blokken har integreret PCS, skal den desuden opfylde nettilslutningskrav (f.eks. Energinets tekniske forskrifter) på systemniveau.
Ofte stillede spørgsmål
Ofte stillede spørgsmål
Hvad er forskellen mellem en AC-blok og en DC-blok?
En AC-blok integrerer batteri og PCS i én enhed og leverer vekselstrøm direkte. En DC-blok indeholder kun batteriet, BMS og termisk styring — den kræver en separat ekstern PCS til nettilslutning. AC-blokke forenkler integrationen; DC-blokke giver mere arkitektonisk fleksibilitet.
Hvornår bør man vælge en AC-blok frem for en DC-blok?
AC-blokke er særligt velegnede til C&I-applikationer, mindre utility-scale-projekter og situationer, hvor hurtig idriftsættelse, færre leverandører og minimalt BoP er vigtigere end fuld arkitektonisk fleksibilitet. For store utility-scale-projekter (50+ MWh) foretrækker de fleste projektudviklere DC-blokke med separat PCS for at optimere indkøb og systemdesign uafhængigt.
Hvilke certificeringer skal en AC-blok have?
AC-blokke kræver de samme basiscertificeringer som DC-blokke (UL 9540A, IEC 62619) plus yderligere akkrediteringer for den integrerede PCS, herunder konformitet med netkoder (Energinets tekniske forskrifter) og sikkerhed for effektelektronik (IEC 62477). Da AC-blokken er en fuldt integreret enhed, skal systemtests dække samspillet mellem alle komponenter.
Hvad er det typiske kapacitetsområde for AC-blokke?
AC-blokke spænder fra ca. 215 kWh (kompakte C&I-enheder) til mere end 10 MWh (utility-scale containerprodukter). De fleste C&I AC-blokke ligger mellem 200 kWh og 1 MWh, mens utility-scale-varianter typisk tilbyder 3–10 MWh pr. enhed. Valget afhænger af projektstørrelse, anlægsrestriktioner og den ønskede systemarkitektur.
