Bolehkah forklift litium benar-benar dicas semasa digunakan? Beberapa salah faham biasa tentang bateri.

Dengan penggunaan meluas forklift elektrik dalam senario seperti logistik pergudangan, forklift litium secara beransur-ansur menjadi pilihan arus perdana berdasarkan kelebihan perlindungan alam sekitar dan kecekapannya. Semasa penggunaan, keupayaan "caj semasa penggunaan" dan ralat penggunaan berkaitan bateri forklift litium telah menjadi tumpuan perhatian pengguna. Artikel ini akan menggabungkan ciri kerja bateri litium-elektrik, menghuraikan salah guna biasa, membantu pengguna memahami dan mengekalkan bateri dengan betul, memanjangkan hayat perkhidmatan dan meningkatkan kecekapan penggunaan peralatan.

Mitos 1: Trak forklift litium mesti dicas sepenuhnya dan digunakan semula.

Ramai pengguna percaya bahawa untuk memastikan kuasa forklift mencukupi, bateri mesti dicas sepenuhnya dan digunakan. Malah, bateri litium-ion, tidak seperti bateri asid plumbum tradisional, tidak mempunyai "kesan ingatan" yang jelas dan tidak perlu diaktifkan oleh kitaran "nyahcas sepenuhnya-cas penuh". Sebaliknya, nyahcas berlebihan, seperti cas kurang daripada 10%, akan menyebabkan sukar untuk membenamkan ion litium di dalam bateri dan menjejaskan kestabilan bahan elektrod. Dalam jangka panjang, ia akan mengurangkan kapasiti bateri dan hayat kitaran. Cara yang betul ialah: mengecas apabila kuasa bateri jatuh kepada 20% -30%, mengelakkan penggunaan semula selepas habis sepenuhnya, ia boleh menjamin kesinambungan kerja dan mengurangkan kerosakan pada bateri akibat nyahcas dalam.

Mitos 2: Pengecasan yang kerap boleh memendekkan hayat bateri.

Sesetengah pengguna bimbang bahawa mengecas forklift litium dengan kerap akan mempercepatkan penuaan bateri. Tetapi berdasarkan prinsip pengecasan dan nyahcas bateri litium-ion, hayat bateri bergantung terutamanya pada "masa nyahcas dalam" dan "persekitaran suhu tinggi". Jika setiap pengecasan menggunakan "cas cetek dan nyahcas cetek" (seperti 80% hingga 20% cas penuh bagi setiap penggunaan), ia bersamaan dengan mengurangkan bilangan nyahcas dalam, tetapi sebaliknya membantu memanjangkan hayat kitaran bateri. Sebagai contoh, jika forklift beroperasi 3 kali sehari, penggunaan elektrik berjulat dari 80% hingga 20% bagi setiap penggunaan, dan jumlah nyahcas ialah 60%, ia jauh lebih rendah daripada kitaran dalam yang mengecas semula selepas nyahcas sepenuhnya. Oleh itu, dalam julat yang munasabah (seperti pengisian semula jurang kerja setiap hari), pengecasan yang kerap akan memberi kesan kecil terhadap hayat bateri, dan tidak perlu risau.

Mitos 3: Semakin lama masa pengecasan, semakin banyak bateri dicas.

Sesetengah pengguna sudah terbiasa mengecas bateri pada waktu malam atau semasa tempoh bukan operasi untuk jangka masa yang lama, memikirkan bahawa "semakin lama masa pengecasan, semakin banyak bateri yang ada". Tetapi sebenarnya, bateri forklift litium biasanya dilengkapi dengan litar perlindungan pintar, dan secara automatik akan memasuki keadaan pengecasan terapung atau trickle apabila bateri sudah penuh, kecekapan pengecasan adalah sangat rendah pada masa ini, dan bateri yang berterusan dalam keadaan voltan tinggi boleh menyebabkan bahan elektrod menjana haba dan mengurai elektrolit, seterusnya menjejaskan prestasi dan jangka hayat bateri. Secara umumnya, mengikut masa pengecasan standard yang ditetapkan oleh manual pengecas, adalah disyorkan agar bekalan elektrik diputuskan dalam masa selepas bateri penuh untuk mengelakkan pengecasan jangka panjang.

Mitos 4: Ia tidak boleh digunakan jika kecekapan pengecasan rendah dalam persekitaran suhu rendah.

Dalam persekitaran suhu rendah pada musim sejuk, aktiviti bateri forklift litium akan berkurangan dan kelajuan pengecasan mungkin menjadi lebih perlahan, oleh itu sesetengah pengguna berpendapat bahawa "ia tidak boleh digunakan pada suhu rendah". Sebenarnya, kesan suhu rendah pada bateri boleh diterbalikkan: jika forklift beroperasi dalam persekitaran suhu rendah, bateri boleh dipindahkan ke persekitaran dalaman (suhu melebihi 5 ° C) untuk mengecas, atau pengecas dengan fungsi pampasan suhu dipilih untuk menyesuaikan diri dengan suhu rendah dengan melaraskan arus pengecasan dan voltan. Sebelum mengecas, suhu permukaan bateri boleh ditingkatkan kepada kira-kira 15 ° C, yang boleh meningkatkan kecekapan pengecasan dengan berkesan. Di samping itu, elakkan menyimpan bateri yang dinyahcas sepenuhnya untuk jangka masa yang lama dalam persekitaran suhu rendah, yang boleh mengekalkan cas dengan sewajarnya sebanyak 20% -30%, dan mengurangkan kerosakan suhu rendah pada bateri.

Mitos 5: Tidak mengapa jika bateri sudah habis dicas dan dicas semula.

Sesetengah pengguna percaya bahawa "bateri boleh dicas semula dan dicas semula", tetapi nyahcas berlebihan (seperti bateri di bawah 5%) akan menyukarkan ion logam litium untuk membenamkan sepenuhnya bahan elektrod negatif untuk membentuk "kristal cawangan litium", boleh menembusi diafragma untuk menimbulkan risiko keselamatan dan mengurangkan kapasiti bateri secara tidak dapat dipulihkan. Oleh itu, apabila tahap bateri ditunjukkan kurang daripada 20%, cas harus dimulakan tepat pada masanya untuk mengelakkan pelepasan bateri yang berlebihan. Dalam penggunaan harian, adalah disyorkan untuk membentuk tabiat "cas kecil tepat pada masanya dan cas besar tidak habis", supaya bateri sentiasa berada dalam julat cas dan nyahcas yang munasabah, yang boleh menjamin keselamatan dan memanjangkan hayat perkhidmatan.

Ringkasan: Keupayaan "cas semasa penggunaan" bateri forklift litium bergantung pada tabiat penggunaan yang betul. Dengan mengelakkan nyahcas berlebihan, mengawal masa pengecasan secara munasabah, dan mengoptimumkan strategi penggunaan dalam persekitaran suhu rendah, pengguna boleh memanjangkan hayat bateri dengan berkesan dan meningkatkan kecekapan operasi forklift. Dalam operasi sebenar, kelebihan forklift litium perlu digabungkan dengan manual peranti dan ciri bateri untuk penyelenggaraan saintifik.
