Analisis mendalam: Hukum masa pakai dan redaman baterai lithium

Analisis mendalam: Hukum masa pakai dan redaman baterai lithium(tokoh1)

Dengan popularitas forklift lithium-ion di pergudangan, logistik, dan skenario lainnya, masa pakai dan redaman siklus baterai telah menjadi indikator biaya inti yang diperhatikan pengguna. Memahami undang-undang yang relevan dapat secara efektif membantu pengguna menggunakan baterai secara rasional dan mengurangi biaya operasi jangka panjang.

Umur siklus baterai forklift litium memiliki standar penilaian industri yang jelas. Biasanya, ketika kapasitas aktual yang dapat digunakan baterai turun menjadi 80% dari kapasitas pengenal, jumlah total siklus pengisian dan pelepasan yang diselesaikan sebelumnya adalah masa pakai siklus nominal baterai. Siklus pengisian dan pelepasan lengkap di sini mengacu pada proses lengkap pemakaian baterai dari keadaan terisi penuh ke tegangan cut-off yang ditetapkan dan kemudian mengisinya hingga tegangan pengenal. Muatan dangkal dan pelepasan dangkal dalam penggunaan sehari-hari tidak akan dihitung sebagai satu siklus, sehingga jumlah total siklus dalam penggunaan sebenarnya seringkali lebih tinggi dari nilai dasar nominal produk.

Di bawah skenario penggunaan yang berbeda, tingkat redaman baterai forklift lithium-ion bervariasi secara signifikan. Dalam skenario operasi konvensional, suhu lingkungan dipertahankan antara 10 derajat Celcius dan 30 derajat Celcius, beban operasi tunggal tidak melebihi 70% dari beban pengenal, dan ke dalaman pelepasan tunggal dikendalikan sekitar 60%. Tingkat redaman baterai akan tetap pada tingkat rendah. Untuk setiap 100 siklus lengkap, penurunan kapasitas biasanya antara 0,3% dan 0,5%. Jika berada di lingkungan operasi yang ekstrim untuk waktu yang lama, seperti suhu lingkungan lebih rendah dari minus 10 derajat Celcius atau lebih tinggi dari 45 derajat Celcius, atau sering dibuang dengan beban penuh dan arus besar, dan baterai dikosongkan ke tegangan cut-off setiap kali sebelum mengisi daya, tingkat redaman baterai akan meningkat 2 hingga 3 kali. Dalam lingkungan suhu tinggi, konsumsi elektrolit internal juga dapat meningkat, yang selanjutnya memperpendek masa pakai baterai yang sebenarnya.

Kuasai metode penggunaan dan pemeliharaan yang wajar, yang secara efektif dapat menunda redaman baterai dan memperpanjang masa pakai siklus. Dalam manajemen pengisian dan pelepasan harian, cobalah untuk menghindari pengosongan muatan pendorong baterai sepenuhnya, dan isi ulang baterai tepat waktu setelah operasi. Ketika baterai menganggur untuk waktu yang lama, pertahankan daya antara 40% dan 60%. Selesaikan pengisian dan pelepasan penuh setiap 1 hingga 2 bulan, dan kalibrasi parameter kapasitas baterai. Cobalah untuk menghindari lingkungan suhu ekstrem selama operasi. Dalam cuaca suhu tinggi atau suhu rendah, waktu operasi tunggal dapat dipersingkat dengan tepat untuk menghindari baterai terlalu panas atau terlalu dingin untuk waktu yang lama. Periksa kontak antarmuka baterai setiap kuartal selama perawatan harian untuk menghindari keputihan abnormal yang disebabkan oleh kontak yang buruk, bersihkan debu dan minyak di permukaan baterai tepat waktu, dan jaga agar saluran pembuangan panas tidak terhalang, yang juga dapat mengurangi kemungkinan abnormal. redaman.
