Blok DC ialah unit kendiri yang menggabungkan modul bateri, rak, BMS dan pengurusan terma bersepadu dalam satu set sedia beroperasi dalam arus terus. Dalam BESS skala utiliti, berbilang blok DC disambungkan kepada PCS (sistem penukaran kuasa) berpusat atau bertali yang menukarkan arus terus kepada arus ulang-alik serasi grid. Blok DC ialah tahap di mana pasukan perolehan menilai kapasiti tenaga, kerumitan penyepaduan sistem dan tingkah laku degradasi jangka panjang — dan merupakan item CAPEX terbesar dalam BESS.
Kebanyakan blok DC skala utiliti menggunakan kimia LFP dalam format kontena atau kabinet dengan kapasiti 4–9+ MWh. Penyejukan cecair kini menjadi standard untuk projek berbilang megawatt-jam — membolehkan suhu sel lebih seragam dan ketumpatan kuasa lebih tinggi berbanding penyejukan udara.
Spesifikasi utama
Apa yang perlu dibandingkan semasa menilai blok DC
Semasa menyenarai pendek untuk projek BESS, berikut ialah spesifikasi teknikal utama yang biasanya dinilai oleh syarikat EPC, pemaju dan pengintegrasi sistem:
Kadar C
0.25C – 1C
Kadar C menentukan kuasa maksimum cas/nyahcas berbanding kapasiti. Kadar C lebih tinggi (≥ 0.5C) membolehkan penimbunan hasil; kadar lebih rendah (0.25C) mengoptimumkan kitaran lebih perlahan dan degradasi lebih rendah.
Kapasiti tenaga
4 – 9+ MWh
Kapasiti tenaga setiap blok DC mempengaruhi secara langsung keluasan tapak, kerumitan pendawaian dan kos. Blok lebih besar mengurangkan bilangan unit dan sambungan BoP yang diperlukan.
Kimia
LFP dominan
LFP ialah kimia standard untuk blok DC skala utiliti kerana keselamatan dan jangka hayat kitarannya. Sesetengah pengeluar menawarkan varian NMC untuk aplikasi di mana ketumpatan tenaga menentukan.
Kecekapan kitaran penuh
85 – 95%
Diukur pada peringkat blok DC (kecekapan kitaran penuh AC termasuk juga kerugian PCS dan pengubah). Kecekapan lebih tinggi meningkatkan LCOS dan keuntungan arbitraj.
Kaedah penyejukan
Cecair atau udara
Penyejukan cecair membolehkan ketumpatan kuasa lebih tinggi dan suhu sel lebih seragam. Penyejukan udara lebih mudah tetapi sedang digantikan oleh penyejukan cecair dalam skala utiliti.
Pensijilan
UL 9540A, IEC 62619
UL 9540A menilai tingkah laku penyebaran kebakaran di peringkat sistem. IEC 62619 meliputi keselamatan sel bateri. Keperluan serantau mungkin menuntut standard tambahan.

Apakah perbezaan antara blok DC dan blok AC?
Blok DC membekalkan arus terus dan perlu disambungkan kepada PCS luaran yang menukarkan arus kepada arus ulang-alik serasi grid. Blok AC menyepadukan PCS dan bateri dalam satu unit dan membekalkan arus ulang-alik secara terus. Blok DC menawarkan lebih fleksibiliti seni bina dan diutamakan untuk kebanyakan projek skala utiliti, manakala blok AC memudahkan penyepaduan dan lebih biasa dalam aplikasi C&I bersaiz kecil.
Mengapa kebanyakan projek BESS skala utiliti menggunakan blok DC?
Blok DC membolehkan pemaju dan syarikat EPC memilih pembekal PCS dan pengeluar bateri secara bebas, serta mengoptimumkan seni bina sistem (berpusat vs bertali) mengikut keperluan setiap projek. Modulariti ini meningkatkan kedudukan perundingan dalam perolehan, memudahkan penggantian di bawah waranti dan membolehkan peluasan kapasiti yang lebih ekonomi sepanjang hayat projek.
Apakah pensijilan yang diperlukan untuk blok DC?
Dua pensijilan yang paling kerap diminta ialah UL 9540A (kaedah ujian penyebaran kebakaran di peringkat sistem) dan IEC 62619 (keperluan keselamatan untuk bateri litium-ion industri). Bergantung pada rantau dan pemaju, standard tambahan mungkin diperlukan, seperti UN 38.3 (pengangkutan), IEC 62477 (keselamatan peralatan elektronik kuasa), penarafan IP dan keperluan perlindungan kebakaran khusus projek.
Bagaimana kapasiti blok DC mempengaruhi kos projek?
Blok DC lebih besar (cth. 5+ MWh setiap unit) mengurangkan jumlah unit yang diperlukan untuk projek, sekali gus mengurangkan pendawaian, BoP dan usaha pemasangan. Walau bagaimanapun, unit lebih besar memerlukan peralatan angkat lebih berat untuk pengangkutan dan penempatan. Pasukan perolehan perlu mengimbangi saiz blok DC dengan logistik tapak, keperluan asas dan strategi peluasan kapasiti.
