I te wā e hoahoa ana, e whakawhānui ana rānei i ngā pūnaha pākahiko, ka ara ake tētahi pātai noa: Ka taea te hono raupapa i ngā kete pākahiko e rua me te ngaohiko kotahi? Ko te whakautu poto koāe, engari me whai i tētahi whakaritenga matua:te kaha o te ara iahiko tiaki ki te tu atu i te ngaohikome arotake marie. Kei raro nei, ka whakamāramahia e mātou ngā taipitopito hangarau me ngā whakatūpato hei whakarite i te mahi haumaru me te pono.
Te Mārama ki ngā Here: Te Manawanui Ngaohiko o te Ara Tiaki
Ko ngā pākahiko lithium he mea whakarite ki tētahi Poari Arataki Tiaki (PCB) hei ārai i te utu nui rawa, te tukunga nui rawa, me ngā ara iahiko poto. Ko tētahi tawhā matua o tēnei PCB ko tete whakatauranga ātete ngaohiko o ana MOSFET(ngā pana hiko e whakahaere ana i te rere o te iahiko).
Tauira Horopaki:
Hei tauira, tangohia kia rua ngā pākahiko LiFePO4 4-pūtau. Ko te ngaohiko utu katoa o ia pākahiko he 14.6V (3.65V mō ia pūtau). Ki te honoa raupapa, ka noho te ngaohiko whakakotahi hei29.2VKo te PCB tiaki pākahiko paerewa 12V he mea hanga noa me ngā MOSFET kua whakatauria mō35–40VI tēnei wā, ka taka te ngaohiko katoa (29.2V) ki roto i te awhe haumaru, e āhei ai ngā pākahiko ki te mahi tika i roto i te raupapa.
Te Mōrearea o te Whakaeke i ngā Here:
Heoi, ki te honoa e koe ētahi kete pēnei e whā i roto i te raupapa, ka nui ake te ngaohiko katoa i te 58.4V—he nui rawa atu i te manawanui 35–40V o ngā PCB paerewa. Ka puta he tūponotanga huna:
Te Pūtaiao kei Muri i te Mōrearea
Ina honoa ngā pākahiko i roto i te raupapa, ka tāpirihia ō rātou ngaohiko, engari ka mahi takitahi ngā ara iahiko tiaki. I raro i ngā āhuatanga noa, ka whakakahangia te kawenga e te ngaohiko whakakotahi (hei tauira, he taputapu 48V) me te kore he raruraru. Heoi, ki tekotahi te pākahiko e whakaoho ana i te tiaki(hei tauira, nā te nui rawa o te tukunga hiko, te nui rawa rānei o te iahiko), ka momotuhia taua kete e āna MOSFET mai i te ara iahiko.
I tēnei wā, ka whakamahia te ngaohiko katoa o ngā pākahiko e toe ana i roto i te raupapa puta noa i ngā MOSFET kua momotuhia. Hei tauira, i roto i te tatūnga e whā-pūkete, ka tata te anga atu o te PCB kua momotuhia58.4V—e neke atu ana i tōna whakatauranga 35–40V. Tērā pea ka rahua ngā MOSFET nā te meapakaru hiko, ka whakakorea tūturutia te ara iahiko tiaki, ka waiho te pākahiko kia ngoikore ki ngā mōrearea a meake nei.
Ngā Otinga mō ngā Hononga Raupapa Haumaru
Hei karo i ēnei tūponotanga, whai i ēnei aratohu:
1.Tirohia ngā Whakatakotoranga a te Kaihanga:
Me manatoko tonu mēnā kei te whakatauria te PCB tiaki o tō pākahiko mō ngā tono raupapa. Ko ētahi PCB he mea hanga motuhake hei whakahaere i ngā ngaohiko teitei ake i roto i ngā whirihoranga maha-pōkai.
2.Ngā PCB Ngaohiko-Tiketike Ritenga:
Mō ngā kaupapa e hiahia ana kia maha ngā pākahiko i roto i te raupapa (hei tauira, ngā pūnaha rokiroki hiko pūngao rā, ngā pūnaha hiko hiko rānei), whiriwhiria ngā ara iahiko tiaki me ngā MOSFET ngaohiko teitei kua whakaritea. Ka taea te whakarite i ēnei kia tu atu i te ngaohiko katoa o tō whakatakotoranga raupapa.
3.Hoahoa Taurite:
Me whakarite kia ōrite te kaha, te pakeke, me te hauora o ngā pākahiko katoa o te raupapa hei whakaiti i te mōrearea o te whakaoho kore taurite o ngā tikanga tiaki.
Ngā Whakaaro Whakamutunga
Ahakoa he mea taea te hono raupapa i ngā pākahiko ngaohiko-rite, ko te wero tūturu kei te whakarite kiaKa taea e ngā ara iahiko tiaki te whakahaere i te ahotea ngaohiko whakaemiMā te whakatairanga i ngā whakatakotoranga wāhanga me te hoahoa matatau, ka taea e koe te whakawhanui haumaru i ō pūnaha pākahiko mō ngā tono ngaohiko teitei ake.
I DALY, ka tukuna e mātoungā otinga PCB whakaritengame ngā MOSFET ngaohiko-tiketike hei whakatutuki i ngā hiahia hononga raupapa matatau. Whakapā mai ki tā mātou tīma ki te hoahoa i tētahi pūnaha hiko haumaru ake, pono ake hoki mō āu kaupapa!
