Kua whakaaro koe me pēhea teBMSka taea te kite i te iahiko o te pākahiko lithium? He mita maha kei roto?
Tuatahi, e rua ngā momo Pūnaha Whakahaere Pūhiko (BMS): te putanga atamai me te putanga pūmārō. Ko te BMS atamai anake ka taea te tuku mōhiohio o nāianei, engari kāore i te putanga pūmārō.
Ko te BMS he mea hanga i tētahi ara iahiko whakahaere whakauru (IC), he pana MOSFET, he ara iahiko aroturuki au, me ngā ara iahiko aroturuki pāmahana. Ko te wāhanga matua o te putanga atamai ko te IC whakahaere, e mahi ana hei roro o te pūnaha tiaki. Ko ia te kawenga mō te aroturuki wā-tūturu o te au o te pākahiko. Mā te hono atu ki te ara iahiko aroturuki au, ka taea e te IC whakahaere te tiki tika i ngā mōhiohio e pā ana ki te au o te pākahiko. Ina nui ake te au i ngā rohe haumaru kua whakaritea, ka tere te whakatau a te IC whakahaere, ā, ka whakahohe i ngā mahi tiaki e rite ana.
Nā, me pēhea te kimi i te au?
I te nuinga o te wā, ka whakamahia he pūoko pānga Hall hei aroturuki i te iahiko. Ka whakamahia e tēnei pūoko te whanaungatanga i waenga i ngā papa aukume me te iahiko. Ina rere te iahiko, ka puta he papa aukume huri noa i te pūoko. Ka tukuna e te pūoko he tohu ngaohiko e rite ana i runga i te kaha o te papa aukume. Kia whiwhi te IC whakahaere i tēnei tohu ngaohiko, ka tatauhia e ia te rahi o te iahiko tuturu mā te whakamahi i ngā rauropi ā-roto.
Mena ka nui ake te iahiko i te uara haumaru kua whakaritea, pērā i te iahiko nui rawa atu, te iahiko poto-poto rānei, ka tere te whakahaere a te IC whakahaere i ngā pana MOSFET hei tapahi i te ara iahiko, hei tiaki i te pākahiko me te pūnaha iahiko katoa.
Hei tāpiritanga, ka whakamahia pea e te BMS ētahi ātete me ētahi atu wāhanga hei āwhina i te aroturuki i te au. Mā te ine i te hekenga ngaohiko puta noa i te ātete, ka taea te tatau i te rahi o te au.
Ko tēnei raupapa o ngā hoahoa ara iahiko matatini, tika hoki, me ngā tikanga whakahaere e aro ana ki te aroturuki i te iahiko o te pākahiko me te tiaki hoki i ngā āhuatanga o te iahiko nui. He mahi nui tā rātou ki te whakarite i te whakamahinga haumaru o ngā pākahiko lithium, te whakaroa i te ora o te pākahiko, me te whakarei ake i te pono o te pūnaha pākahiko katoa, inā koa i roto i ngā tono LiFePO4 me ētahi atu pūnaha raupapa BMS.
