Pendahuluan<\/strong><\/p>\n\n\n\n

Karena kendaraan listrik (EV) dan sistem penyimpanan energi (ESS) terus mempercepat transisi energi global, manajemen termal baterai telah menjadi faktor penting yang menentukan kinerja, umur panjang, dan keamanan sistem. Artikel ini memberikan analisis teknis yang komprehensif tentang sistem manajemen termal baterai berpendingin cairan (BTMS) kelas 8kW, berdasarkan implementasi teknik praktis dan praktik terbaik industri.<\/p>\n\n\n\n

Gambaran Umum Arsitektur Sistem<\/strong><\/p>\n\n\n\n

Komponen Inti<\/strong><\/p>\n\n\n\n

BTMS berpendingin cairan 8kW biasanya terdiri dari empat subsistem utama:<\/p>\n\n\n\n

1.<\/strong>Pendinginan Cairan - Termasuk pelat pendingin paduan aluminium yang tahan korosi, pompa sentrifugal levitasi magnetik, dan tangki ekspansi. Rentang penyesuaian laju aliran berkisar antara 0,5-8 L\/menit dengan toleransi tekanan pipa sebesar 1,6MPa.<\/p>\n\n\n\n

2.<\/strong>Subsistem Pertukaran Panas - Menggunakan penukar panas sirip pelat yang dikombinasikan dengan kompresi elektronik untuk mencapai arsitektur pertukaran panas dua tahap. Akurasi pengisian refrigeran mencapai \u00b15g, dengan efisiensi pertukaran panas melebihi 92%.<\/p>\n\n\n\n

3.<\/strong>Unit Kontrol Cerdas - Dilengkapi dengan pengontrol MCU 32-bit yang mengintegrasikan bus CAN dan antarmuka komunikasi RS485. Sistem memonitor 16 saluran sensor suhu dan 4 saluran sensor tekanan dengan latensi respons di bawah 50ms.<\/p>\n\n\n\n

4.<\/strong>Mekanisme Perlindungan Keselamatan - Menerapkan perlindungan kesalahan tiga tingkat (peringatan\/penundaan\/pematian daya) dengan kemampuan intervensi dini untuk pelarian termal melalui deteksi gas dan katup pelepas tekanan, sesuai dengan standar keselamatan UL1973.<\/p>\n\n\n\n

Prinsip Kerja<\/strong><\/p>\n\n\n\n

Sistem ini menggunakan penukar panas tipe sayap pelat yang dikombinasikan dengan kompresor elektronik untuk membentuk arsitektur pertukaran panas sekunder. Campuran pendingin air + glikol 50% bersirkulasi melalui kemasan baterai, menyerap energi panas dan memindahkannya ke sirkuit pendingin untuk dibuang.<\/p>\n\n\n\n

Spesifikasi Kinerja Teknis<\/strong><\/p>\n\n\n\n

Presisi Kontrol Suhu<\/strong><\/p>\n\n\n\n

Kompatibilitas Baterai<\/strong><\/p>\n\n\n\n

Baterai Lithium Terner (NCM\/NCA)<\/strong><\/p>\n\n\n\n

Beradaptasi dengan baterai dengan kepadatan energi tinggi melalui teknologi pendinginan gradien, mempertahankan perbedaan suhu sel \u22642\u00b0C dan menekan risiko pelapisan litium suhu tinggi.<\/p>\n\n\n\n
