Kua noho ngā pākahiko lithium hei wāhanga nui o te pūnaha hiko hou, e whakakaha ana i ngā mea katoa mai i ngā waka hiko me ngā whare rokiroki hiko ki ngā taputapu hiko kawe. Heoi, ko tētahi wero noa e pā ana ki ngā kaiwhakamahi puta noa i te ao ko te pānga nui o te pāmahana ki te mahi a te pākahiko—he maha ngā wā ka puta mai ngā raruraru pēnei i te pupuhi me te turuturu o te pākahiko i te raumati, ko te takurua ia ka arahi ki te whakaiti nui i te whānuitanga me te ngoikore o te whai huatanga o te utu. Ko te pūtake o tēnei ko te aro ki te pāmahana o ngā pākahiko lithium, me ngā pākahiko lithium rino phosphate, tētahi o ngā momo e whakamahia whānuitia ana, e mahi pai ana i waenga i te 0°C me te 40°C. I roto i tēnei whānuitanga, ka mahi ngā tauhohenga matū ā-roto me te hekenga katote i te tino whai huatanga, e whakarite ana i te putanga pūngao mōrahi.
He nui ngā tūponotanga mō ngā pākahiko lithium i ngā pāmahana i waho atu i tēnei matapihi haumaru. I ngā taiao pāmahana teitei, ka tere ake te mimiti me te pirau o ngā electrolyte, ka whakaiti i te kawe irahiko, ā, ka puta pea he hau e pupuhi ai, e pakaru ai rānei te pākahiko. Hei tāpiri, ka heke te pumau o te hanganga o ngā rauemi electrode, ka mutu ka ngaro te kaha e kore e taea te whakakore. He mea nui ake, ka taea e te wera nui te whakaoho i te rere wera, he tauhohenga mekameka ka hua ake he aituā haumaru, he tino take o ngā hapa i roto i ngā taputapu hiko hou. He rite tonu te raruraru o ngā pāmahana iti: ka whakaroa te pikinga o te matotoru o te electrolyte i te hekenga o te lithium ion, ka piki ake te ātete o roto, ka whakaiti i te pai o te tukunga utu. Ka taea e te utunga ā-kaha i roto i ngā āhuatanga makariri te meinga i ngā ion lithium kia tau ki runga i te mata o te electrode kino, ka hanga i ngā dendrite lithium e wero ana i te wehewehe me te whakaoho i ngā ara iahiko poto o roto, ka puta he tūponotanga nui ki te haumaru.
Hei whakaiti i ēnei mōrearea e pā mai ana i te pāmahana, he mea nui te Poari Tiaki Pūhiko Ritiumu, e mōhiotia whānuitia ana ko te BMS (Pūnaha Whakahaere Pūhiko). Ko ngā hua BMS kounga teitei he pūoko pāmahana NTC tino tika e aroturuki tonu ana i te pāmahana pākahiko. Ina neke atu te pāmahana i ngā rohe haumaru, ka whakaoho te pūnaha i te whakaoho; mēnā ka piki tere te pāmahana, ka whakahohe tonu i ngā mahi tiaki hei tapahi i te ara iahiko, hei ārai i ngā kino atu. Ka taea hoki e te BMS matatau me te arorau whakahaere whakamahana pāmahana iti te waihanga i ngā āhuatanga whakahaere pai rawa atu mō ngā pākahiko i roto i ngā taiao makariri, e aro pai ana ki ngā take pēnei i te whānuitanga iti me ngā uauatanga utu, e whakarite ana i te mahi pumau puta noa i ngā āhuatanga pāmahana rerekē.
Hei wāhanga matua o te pūnaha haumaru pākahiko lithium, ehara i te mea ka tiaki noa te BMS mahi-teitei i te haumaru mahi engari ka whakaroa ake hoki i te roa o te ora o te pākahiko, me te tautoko nui mō te mahi pono o ngā taputapu hiko hou.
