Mai ka pale mua a i ka pale lua
ʻO ka palekana kumu loa, ʻo ia ka palekana overvoltage. Hāʻawi nā IC pale pākahiko lithium āpau i ka palekana overvoltage e like me nā pae palekana like ʻole. Ma kēia kumu, hāʻawi kekahi i ka overvoltage me ka pale overcurrent hoʻokuʻu, a hāʻawi kekahi i ka overvoltage me ka hoʻokuʻu overcurrent me ka pale overheating. No kekahi mau pā pākahiko lithium cell kiʻekiʻe, ʻaʻole lawa kēia palekana e hoʻokō i nā pono o ka pā pākahiko lithium. I kēia manawa, pono kahi IC pale pākahiko lithium me ka hana kaulike kūʻokoʻa pākahiko lithium.

No kēia IC pale kēia pale mua, ka mea e kāohi ana i nā FET hoʻopiʻi a hoʻokuʻu e pane i nā ʻano pale hewa like ʻole. Hiki i kēia kaulike ke hoʻoponopono i ka pilikia o ka holo ʻana o ka wela o kapūʻolo pākahiko lithiummaikaʻi loa. ʻO ka hōʻiliʻili nui ʻana o ka wela i loko o kahi pākahi lithium hoʻokahi e hōʻino i ke kuapo kaulike o ka pākahi pākahi lithium a me nā resistors. ʻO ke kaulike ʻana o ka pākahi lithium e ʻae i kēlā me kēia pākahi lithium kīnā ʻole i loko o ka pākahi pākahi lithium e kaulike ʻia i ka mana like me nā pākahi kīnā ʻē aʻe, e hōʻemi ana i ka pilikia o ka holo ʻana o ka thermal.

I kēia manawa, ʻelua mau ala e hoʻokō ai i ke kaulike ʻana o ka pākahiko lithium: ke kaulike hana a me ke kaulike passive. ʻO ke kaulike hana ka hoʻoili ʻana i ka ikehu a i ʻole ka hoʻopiʻi ʻana mai nā pākahiko voltage kiʻekiʻe/SOC kiʻekiʻe i nā pākahiko SOC haʻahaʻa. ʻO ke kaulike passive ka hoʻohana ʻana i nā resistors e hoʻopau i ka ikehu o nā pākahiko voltage kiʻekiʻe a i ʻole nā ​​​​​​pākaukau kiʻekiʻe e hoʻokō ai i ke kumu o ka hōʻemi ʻana i ka hakahaka ma waena o nā pākahiko like ʻole. Loaʻa i ke kaulike passive ka pohō ikehu kiʻekiʻe a me ka pilikia wela. I ka hoʻohālikelike ʻana, ʻoi aku ka maikaʻi o ke kaulike hana, akā he paʻakikī loa ka algorithm kaohi.
Mai ka pale mua a i ka pale lua, pono e hoʻolako ʻia ka ʻōnaehana pākahiko lithium me kahi mea nānā pākahiko lithium a i ʻole kahi ana wahie e hoʻokō ai i ka pale lua. ʻOiai hiki i ka pale mua ke hoʻokō i nā algorithms kaulike pākahiko akamai me ka ʻole o ka mana MCU, pono ka pale lua e hoʻouna i ka volta pākahiko lithium a me ke au i ka MCU no ka hoʻoholo ʻana i ka pae ʻōnaehana. Loaʻa i nā mea nānā pākahiko lithium a i ʻole nā ​​​​anakahi wahie nā hana kaulike pākahiko.
