Hiki ke hoʻokumu ʻia kahi ʻeke pākaukau ma ka hoʻopili ʻana i kekahi mau pākahi lithium i ka moʻo, ʻaʻole hiki ke hāʻawi wale i ka mana i nā ukana like ʻole, akā hiki ke hoʻopiʻi maʻamau me kahi charger pili.'A'ole koi 'ia nā pila Lithium i kekahi 'ōnaehana ho'okele pila (BMS) e ho'ouka a ho'oku'u.No laila no ke aha i hoʻohui ʻia ai nā pākahi lithium āpau ma ka mākeke me BMS?ʻO ka pane ka palekana a me ka lōʻihi.
Hoʻohana ʻia ka ʻōnaehana hoʻokele pākaukau ʻo BMS (Battery Management System) e nānā a hoʻokele i ka hoʻouka ʻana a me ka hoʻokuʻu ʻana i nā ʻenekini hiki ke hoʻouka hou ʻia.ʻO ka hana koʻikoʻi o ka ʻōnaehana hoʻokele pākaukau lithium BMS ʻo ia ka hōʻoia ʻana i ka noho ʻana o ka pākaukau i loko o kahi pae hana palekana a e hana koke i ka hana inā hoʻomaka kekahi pākahi ma mua o ka palena.Inā ʻike ka BMS he haʻahaʻa loa ka uila, e hoʻokaʻawale ia i ka ukana, a inā kiʻekiʻe loa ka uila, e kāpae i ka charger.E nānā pū ʻo ia i kēlā me kēia cell i loko o ka pūʻolo i ka volta like a hāʻule i kekahi i ʻoi aku ka kiʻekiʻe ma mua o nā cell ʻē aʻe.ʻO kēia ka mea e hōʻoia ai ʻaʻole hiki i ka pākaukau ke piʻi i nā voltage kiʻekiʻe a haʻahaʻa paha - ʻo ia ke kumu o ke ahi ʻana o ka pā lithium a mākou e ʻike nei ma ka nūhou.Hiki iā ia ke nānā i ka wela o ka pākaukau a hoʻokaʻawale i ka pūʻolo pila ma mua o ka wela a wela i ke ahi.No laila, ʻo ka ʻōnaehana hoʻokele pākaukau ʻo BMS ka mālama ʻana i ka pākaukau ma mua o ka hilinaʻi wale ʻana i kahi loina maikaʻi a i ʻole ka hana hoʻohana pololei.
No ke aha ʻaʻole pono nā pākiʻi lead-acid (AGM, gel batteries, deep cycle, etc.) i kahi ʻōnaehana hoʻokele pila?ʻAʻole hiki ke hoʻopau ʻia nā ʻāpana o nā pākī lead-acid a ʻoi aku ka liʻiliʻi o ke ahi inā pilikia ka hoʻouka ʻana a i ʻole ka hoʻokuʻu ʻana.Akā ʻo ke kumu nui e pili ana i ke ʻano ke hoʻopiha piha ʻia ka pākaukau.Ua hana pū ʻia nā ʻakika Lead-acid me nā pūnaewele i hoʻopili ʻia i ka moʻo;inā ʻoi aku ka nui o ka hoʻouka ʻana o kekahi kelepona ma mua o nā ʻāpana ʻē aʻe, e ʻae wale ia e hele i ke au a hiki i ka piha ʻana o nā kelepona ʻē aʻe, ʻoiai e mālama ana i ka uila kūpono iā ia iho, a pēlā aku.Ma kēia ala, ʻo ka pākaukau lead-acid "kaulike pono" e like me ka uku.
ʻOkoʻa nā ʻōhua lithium.ʻO ka electrode maikaʻi o ka pā lithium rechargeable ka hapa nui o nā mea lithium ion.ʻO kāna kumu hana e hoʻoholo ai i ka wā o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana, e holo hou nā electrons lithium i nā ʻaoʻao ʻelua o nā electrodes maikaʻi a maikaʻi ʻole.Inā ʻae ʻia ke kiʻekiʻe o ka volta o ke kelepona hoʻokahi ma mua o 4.25v (koe naʻe nā pākahi lithium voltage kiʻekiʻe), hiki ke hāʻule ka anode microporous structure, ulu ka mea crystalline paʻakikī a hana i kahi pōkole pōkole, a laila e piʻi koke ka mahana. , ka mea e hiki ai i ke ahi.Ke hoʻopiha piha ʻia ke kelepona lithium, piʻi koke ka uila a hiki koke i nā pae weliweli.Inā ʻoi aku ka kiʻekiʻe o ka volta o ke kelepona i loko o ka pā pākaukau ma mua o nā cell ʻē aʻe, e hiki mua kēia kelepona i ka volta pōʻino i ka wā o ka hoʻouka ʻana, a ʻaʻole i hiki i ka volta holoʻokoʻa o ka pūʻali pākahi i ka waiwai piha i kēia manawa, ʻaʻole hoʻōki i ka hoʻouka ʻana .No laila, ʻo ke kelepona mua e hiki ai i ka volta pōʻino ke kau nei i kahi pilikia palekana.No laila, ʻaʻole lawa ka hoʻomalu ʻana a me ka nānā ʻana i ka volta holoʻokoʻa o ka puʻupuʻu pākahi no nā kemika i hoʻokumu ʻia i ka lithium, pono e nānā ʻia ka volta o kēlā me kēia cell e hoʻokumu i ka pā pākaukau e ka BMS.
Ma kahi ʻano haiki, hoʻohana ʻia ka ʻōnaehana hoʻokele pākaukau BMS no ka pale ʻana i nā pūʻulu pākaukau nui.ʻO ka hoʻohana maʻamau ka lithium iron phosphate power batteries, nona nā hana pale e like me ka overcharge, overdischarge, overcurrent, short circuit, a me ke kaulike cell.Pono nā awa kamaʻilio, ka hoʻokomo ʻikepili a me nā koho puka a me nā hana hōʻike ʻē aʻe.No ka laʻana, ʻo ka pilina kamaʻilio o ka BMS i hoʻonohonoho pono ʻia ʻo Xinya penei.
Ma ka manaʻo ākea, he Protection Circuit Board (PCB), i kapa ʻia i kekahi manawa he PCM (Protection Circuit Module), he ʻōnaehana hoʻokele maʻalahi BMS.Hoʻohana maʻamau no nā pūʻolo pākahi liʻiliʻi.Hoʻohana maʻamau no nā ʻōhua kikohoʻe, e like me nā ʻona kelepona paʻa, nā ʻoni kamera, nā ʻona GPS, nā ʻeke lole hoʻomehana, a me nā mea ʻē aʻe. overdischarge, overcurrent, and short circuit.Pono paha kekahi mau pila i ka PTC a me NTC.
No laila, no ka hōʻoia ʻana i ka palekana a me ka lōʻihi o ka lawelawe ʻana o nā pā uila lithium, pono maoli kahi ʻōnaehana hoʻokele pākaukau BMS me ka maikaʻi hilinaʻi.
