Perbandingan trak forklift penyimpanan sejuk asid plumbum dan bateri litium: penerangan laluan teknikal model BYD.

Perbandingan trak forklift penyimpanan sejuk asid plumbum dan bateri litium: penerangan laluan teknikal model BYD.(Rajah1)

Persekitaran storan sejuk berada dalam keadaan suhu rendah dan kelembapan tinggi sepanjang tahun, dan mempunyai keperluan yang lebih tinggi untuk kestabilan dinamik, rintangan kakisan dan prestasi hayat perkhidmatan forklift. Forklift penyimpanan sejuk di pasaran semasa terbahagi terutamanya kepada dua laluan kuasa bateri asid plumbum dan bateri litium. Terdapat senario penyesuaian untuk setiap jenis model, dan terdapat juga perbezaan yang ketara dalam laluan penyelidikan dan pembangunan teknologi.

Forklift penyimpanan sejuk berkuasa asid plumbum ialah jenis produk yang lebih awal dan popular, dengan kematangan teknikal yang tinggi, kos pembelian yang agak rendah, proses penyelenggaraan dan penggantian bateri yang mudah, sesuai untuk penyimpanan sejuk kecil dengan kekuatan operasi yang rendah dan masa operasi harian kurang daripada 4 jam. Walau bagaimanapun, bateri asid plumbum mempunyai kebolehsuaian suhu rendah, kecekapan nyahcas akan dilemahkan dengan ketara dalam persekitaran di bawah 0 ° C konvensional, dan penurunan dalam jangka hayat biasanya antara 30% dan 40%. Pada masa yang sama, masa pengecasan boleh mengambil masa 8 hingga 10 jam. Kawasan pengecasan pengudaraan dan pengecasan khas perlu dikhaskan. Fenomena esterilan gas yang dihasilkan semasa penggunaan juga boleh mencemarkan barang yang disimpan di dalam storan sejuk tertutup.

Forklift storan sejuk berkuasa litium ialah kategori arus perdana yang dipromosikan dalam beberapa tahun kebelakangan ini. Kesesuaian suhu kriogenik lebih kuat. Kecekapan nyahcas dalam persekitaran -20 ° C masih boleh dikekalkan melebihi 85%. Julat pereputan hayat adalah jauh lebih rendah daripada model asid plumbum. Pada masa yang sama, ia menyokong penggunaan dengan pengecasan, tidak perlu menunggu lama untuk dicas, dan boleh disesuaikan dengan keperluan operasi storan sejuk berintensiti tinggi iaitu dua syif dan tiga syif. Bateri litium mempunyai prestasi pengedap yang lebih baik, tiada gas pemusnah dan risiko kebocoran cecair semasa penggunaan. Ia tidak akan menyebabkan pencemaran kepada barangan sensitif seperti makanan dan ubat yang disimpan dalam storan sejuk. Hayat perkhidmatan biasanya 3 hingga 4 kali ganda daripada bateri asid plumbum, dan kos keseluruhan operasi jangka panjang adalah lebih rendah.

Penyelidikan dan pembangunan teknologi model arus perdana semasa tertumpu terutamanya pada pengoptimuman kesesuaian pemandangan bagi dua jenis kuasa. Untuk trak forklift penyimpanan sejuk asid plumbum, terutamanya dengan meningkatkan perumah penebat bateri dan mengoptimumkan formula elektrolit, mengurangkan amplitud pengecilan hayat dalam persekitaran suhu rendah dan meningkatkan kestabilan operasi suhu rendah. Untuk trak forklift penyimpanan sejuk litium-elektrik, ia terutamanya mengoptimumkan algoritma penyesuaian suhu rendah sistem pengurusan bateri, mengukuhkan perlindungan anti-lembapan dan anti-beku bagi litar badan, dan meningkatkan kebolehpercayaan operasi dalam persekitaran suhu rendah yang melampau. Entiti operasi yang berbeza boleh memilih model yang sesuai mengikut julat suhu, kekuatan operasi dan saiz bajet storan sejuk mereka. Model litium lebih diutamakan untuk storan sejuk dengan kekuatan operasi tinggi dan suhu di bawah -10 ° C. Model asid plumbum boleh dipilih untuk penyimpanan sejuk beku yang mempunyai bajet terhad dan tempoh operasi yang lebih pendek melebihi 0 ° C.
