Masalah pereputan bateri suhu rendah: Perkongsian penyelesaian teknikal forklift penyimpanan sejuk elektrik BYD(Rajah1)

Dalam senario operasi pergudangan suhu rendah, salah satu titik kesakitan teras yang dihadapi oleh forklift elektrik ialah masalah pengecilan bateri dalam persekitaran suhu rendah. Ia bukan sahaja akan memendekkan hayat bateri sekali, tetapi juga mengurangkan hayat perkhidmatan keseluruhan bateri dan meningkatkan kos keseluruhan operasi pergudangan. Menjelaskan insentif pengecilan bateri suhu rendah dan memadankannya dengan penyelesaian penyesuaian teknikal yang disasarkan dapat menyelesaikan masalah kesakitan industri ini dengan berkesan.

Pencetus teras pengecilan bateri dalam persekitaran suhu rendah

Persekitaran suhu rendah akan menyebabkan penurunan ketara dalam aktiviti elektrolit di dalam bateri, meningkatkan rintangan penghijrahan ion, secara langsung mengurangkan kecekapan penukaran cas-nyahcas, dan keupayaan nyahcas hanya boleh mencapai 60% hingga 70% daripada keadaan suhu bilik. Selain itu, perbezaan suhu yang dijana oleh pergerakan kerap forklift masuk dan keluar dari gudang sejuk adalah mudah untuk membentuk pemeluwapan pada permukaan gudang bateri dan komponen yang dikawal secara elektronik. Pengumpulan jangka panjang akan menghakis komponen dan memburukkan lagi pengecilan prestasi bateri. Dalam kes yang melampau, ia juga boleh menyebabkan bahaya keselamatan.

Penyelesaian penyesuaian teknikal teras untuk forklift penyimpanan sejuk elektrik

Pengoptimuman bateri dan sistem kawalan suhu

Sesuai untuk pemandangan suhu rendah, bateri dengan julat suhu yang luas, lapisan penebat berketumpatan tinggi dipasang di sekeliling pek bateri pada masa yang sama, dan sistem pemanasan awal pintar dipasang. Apabila suhu ambien lebih rendah daripada ambang yang ditetapkan, sistem akan mengaktifkan fungsi pemanasan awal secara automatik untuk menstabilkan suhu operasi sel dalam julat yang munasabah, mengurangkan kesan suhu rendah pada aktiviti sel daripada punca, dan mengurangkan kehilangan prestasi yang tidak perlu.

Reka bentuk pengedap kenderaan dan anti pemeluwapan

Meningkatkan tahap perlindungan pengedap kartrij bateri dan komponen kawalan elektronik kenderaan, menyembur salutan khas anti-pemeluwapan pada permukaan komponen utama, mengelakkan wap air yang disebabkan oleh perbezaan suhu daripada menceroboh struktur dalaman, mengurangkan risiko hakisan komponen elektronik oleh pemeluwapan, dan memastikan operasi stabil sistem litar kenderaan di bawah senario turun naik perbezaan suhu.

Pelarasan strategi pengecasan dan nyahcas untuk pemandangan suhu rendah

Mengoptimumkan logik pengecasan dan nyahcas kenderaan untuk persekitaran suhu rendah, menurunkan ambang arus nyahcas dengan sewajarnya pada suhu rendah, dan mengelakkan kehilangan sel tambahan yang disebabkan oleh nyahcas semasa yang besar. Proses pra-suhu bateri ditambah pada peringkat pengecasan, dan pengecasan biasa dimulakan selepas suhu bateri meningkat kepada julat yang munasabah untuk mengelakkan masalah seperti bateri maya dan kerosakan sel yang disebabkan oleh pengecasan suhu rendah.

Titik penyelenggaraan harian bateri forklift dalam senario suhu rendah

Cuba elakkan forklift terbiar dalam persekitaran yang melampau di bawah sifar untuk jangka masa yang lama dalam operasi harian, dan letakkan kenderaan di kawasan peralihan dengan suhu sederhana semasa tempoh bukan operasi. Sentiasa periksa integriti lapisan penebat bateri dan struktur pengedap, kerosakan dan penyelenggaraan tepat pada masanya, dan ikuti prosedur pengecasan suhu rendah yang standard dengan ketat, dan jangan terus mengecas kenderaan dalam persekitaran suhu rendah yang melampau.

Penyelesaian teknikal ini telah disahkan secara praktikal oleh sejumlah besar senario pergudangan suhu rendah. Ia boleh mengurangkan kadar pengecilan bateri dengan berkesan dalam persekitaran suhu rendah, memanjangkan hayat perkhidmatan keseluruhan forklift elektrik, membantu pengendali pergudangan suhu rendah mengurangkan kos operasi dan penyelenggaraan yang komprehensif serta meningkatkan kecekapan operasi.
