Nā Luʻi Paʻa Paʻa Forklift: Pehea e hoʻonui ai ʻo BMS i nā hana kiʻekiʻe? 46% Hoʻonui maikaʻi

ʻEkolu Kuleana Paʻa

1. ʻOi aku ka 300A i ka wā e hāpai ana i nā ukana he 3-ton. Hiki i nā papa pale maʻamau ke hoʻomaka i nā pani hoʻopunipuni ma muli o ka pane lohi.
2. ʻOi aku ka mahana o ka pākaukau ma mua o 65°C i ka wā e hana mau ana, e wikiwiki ana i ka ʻelemakule. ʻO ka hoʻokuʻu ʻana i ka wela kūpono ʻole he pilikia ma ka ʻoihana.
3. ʻO nā hewa State-of-Charge (SOC) ʻAʻole i pololei ka helu ʻana o Coulomb (> 5% hewa) ke kumu o ka nalo ʻana o ka mana, hoʻopau i nā kahe hana logistic.

ʻO nā ʻĀpana BMS no nā hiʻohiʻona kiʻekiʻe

ʻO ka pale ʻana o ka millisecond overcurrent

Hoʻohana ʻia nā papa hana MOSFET he nui i ka 500A+ kiʻekiʻe. ʻO ka ʻoki kaapuni i loko o 5ms kaohi i ka hoʻopau ʻana i ka hana (3x ʻoi aku ka wikiwiki ma mua o nā papa kumu).

• Hoʻokele Thermal Dynamic
• ʻO nā kahawai hoʻoluʻu i hoʻohui ʻia + nā puʻu wela e kaupalena i ka piʻi ʻana o ka mahana i ≤8°C ma nā hana waho. Ka mana paepae ʻelua:Hoemi i ka mana ma >45°CHo'ā i ka hoʻomehana mua ma lalo o 0°C
• Ka nānā ʻana i ka mana pololei
• ʻO ka hoʻololi ʻana o ka voltage e hōʻoia i ka pololei o ka pale ʻana i ka ± 0.05V. Loaʻa i ka hui pū ʻana o ka ʻikepili he ≤5% SOC i nā kūlana paʻakikī.
