A BMS lithium— pūnaha whakahaere pākahiko — ko te ara iahiko e tū ana i waenganui i te pākahiko lithium me ngā āhua o te pakaru o ngā pūtau lithium. Ko tētahi hanganga pākahiko nui, ahakoa he lithium-ion (NCM), he LiFePO4, he LTO rānei (lithium titanate), he kotahi tōna, ā, ko te tohu i tēnei ka heke ki ngā whakataunga e whā: te matū me te tatau raupapa me tautoko, te iahiko tonu me kawe e ia, ngā atanga whakawhitiwhiti e hiahiatia ana e te tono, me te tikanga taurite e pupuri ana i ngā pūtau kia tū rite i te roanga o te oranga o te pākahiko.
E whakamārama ana tēnei whārangi i ngā mahi a te pūnaha whakahaere pākahiko mō ngā kete lithium-ion me LiFePO4, kātahi ka whakamāramahia ia whakatau e whā, me ngā awhe whakatakotoranga e kapi ana a DALY i ia taahiraa.
Ngā Mahi a te Lithium BMS
He huinga parenga taketake kei roto i ia BMS lithium: te utu nui, te tukunga nui, te iahiko nui, te pāmahana, me te parenga ara iahiko poto. Ehara ēnei i te āhuatanga utu nui — engari ko te whakamāramatanga o te kāwai hua. Ka aroturukihia e te BMS te ngaohiko o ia rōpū pūtau me te iahiko me te pāmahana o te kete, ā, ka momotu i te ara iahiko matua ina whiti tetahi pānui i tōna paepae parenga; ka whai mai te whakaora ina hoki ngā āhuatanga ki te matapihi haumaru, me te whanonga whakaora tuturu i runga i te momo hapa.
Hei tāpiri atu ki taua tūāpapa, ka tāpirihia e te BMS atamai he ine ka taea e koe te kite me ngā tautuhinga ka taea e koe te whakarerekē: te pānui ngaohiko pūtau-ki-pūtau, te whakatau tataitanga o te āhua o te utu, te takiuru hītori, me te hononga Nihokikorangi ki tētahi taupānga waea mō te aroturuki me te whirihoranga tawhā. Mā ngā whakataunga e whā i raro nei ka whakatau ko tēhea papa e mau ana i aua mahi mō tō kete motuhake.
Whakataunga 1 — Matū me te Tatau Raupapa
Ko te whakatakotoranga tuatahi ko te mea i hangaia ai te kete. Ka whakamahia e te Smart BMS a DALY (A Series) he hoahoa whānui 4–24S (4 ki te 24 pūtau i roto i te raupapa) e kapi ana i ngā matū lithium matua e toru:
| Matū | Awhe Raupapa Tautokona |
|---|---|
| LiFePO4 (LFP) | 4–8H / 7–17H / 7–24H |
| Ritiumu-ion (NCM) | 4–7H / 7–17H / 7–20H |
| LTO | 6–8H / 11–17H / 11–24H |
E rua ngā mahi e whai hua ai te hoahoa whānui i roto i te hanga. Ka taea te whakawhiti matū i roto i te taupānga DALY mā te pāwhiri kotahi, nō reira ka mahi te papa kotahi i tētahi ota LFP i tēnei marama me tētahi ota NCM i te marama e tū mai nei. Ā, ka kitea aunoa te tatau raupapa i roto i te 45 hēkona o te whakakā tuatahi — kāore he pana DIP, kāore he whirihoranga mō ia wae — ko te tikanga ka taea te tuku i tētahi kete pahikara hiko 13S me tētahi kete 16S 48V mai i te taonga BMS kotahi.
Whakataunga 2 — Taumata Tonu o Nāianei
Ko te whakatauranga o nāianei te whakatau me te hua utu tino tika: ki te nui rawa te tohu, ka utua e koe te parahi kāore koe e whakamahi; ki te iti rawa te tohu, ka momotu te BMS i raro i te kawenga tika. E whā ngā taumata o te Raupapa A:
| Taumata o Nāianei | Tonu | Te tihi |
|---|---|---|
| 40A / 60A | 40A / 60A | 60A / 90A |
| 80A / 100A | 80A / 100A | 120A / 150A |
| 150A / 200A | 150A / 200A | 225A / 300A |
| 250A–400A | 250A / 300A / 400A | 375A–600A |
E rua ngā tirotiro e tohu ana i te taumata. Tuatahi, tauritehia te whakatauranga tonu ki te kukume pumau o te kawenga, kaua ki tōna mōrahi papa ingoa. Tuarua, tirohia te pou tihi ki ngā huihuinga ngaru o te tono — ngā tīmatanga motuka, ngā ngaru inverter — nā te mea ko te whakatauranga tihi, ehara i te mea tonu, e whakatau ana mēnā ka eke te BMS mā roto i a rātou. Ina neke atu te whakaritenga o te kete i te 400A tonu, ko teraina BMS au teiteika riro i a ia te mana whakahaere.
Whakataunga 3 — Whakawhitiwhiti Kōrero
He pai te mahi a te kete e tiaki ana anake; he pai ake te hoko atu i te kete e tuku pūrongo ana. Ka tukuna mai te A Series me ngā atanga UART takirua, RS485, me te CAN hei atanga paerewa, me te Nihokikorangi kua hangaia mō te taupānga DALY. Ko te mea e whakamahia ana e tō taupānga ka whakawhirinaki ki te mea kei tera pito o te waea: ko ngā kaitahuri me ngā rihi i roto i ngā pūnaha rokiroki me te nekenekehanga ka whakamahi i te RS485, i te CAN rānei, ko te UART ia ka whakamahi i ngā wae whakaatu me ngā kaiwhakahaere manaaki.
Ko te pātai whakatakotoranga mahi ehara i te mea "ko tēhea pahi te mea pai" engari "he aha te kōrero a te taputapu whiwhi" — ā, nā te mea kei runga i te papa kotahi ngā atanga e toru, ka taea e te tauira BMS kotahi te hipoki i ngā kiritaki i runga i ngā pahi rerekē me te kore e whakarerekē i ngā taputapu.
Whakatau 4 — Te Whakataurite
Ka wehea ngā pūtau i ngā huringa utu, ā, mā te tikanga taurite e whakatau te nui o te rerekētanga ka taea e te BMS te whakatika. Kei te Raupapa A te taurite kore mahi 100mA hei paerewa — he nui hei pupuri i ngā pūtau hou kua taurite pai i roto i te ratonga noa.
Ina ko te ōritetanga o te pūtau te herenga — ngā pūtau kaha nui me te horapa whānui, ngā pūtau ora tuarua, ngā putea rānei e huri hohonu ana i ia rā — teBMS taurite hohe raupapa TKa nekehia te pūngao i waenga i ngā pūtau tae atu ki te 1A mā te whakamahi i te taurite whakawhiti-ahunga rua, puta noa i te awhe 4–24S kotahi, i roto i ngā taumata iahiko mai i te 40A ki te 400A. Kei te wātea hoki he taumata 30A me te taurite hohe ā-whakauru 0.5A mō ngā hanganga LiFePO4 12V iti. He māmā noa te arorau whakatakotoranga: taurite kore mahi taunoa, taurite hohe ina ko ngā pūtau, ehara i te whakatauranga iahiko, te mea whakawhāiti.
Te Whakakotahi i ngā Whakataunga e Whā
Ko te whakatakotoranga katoa o te lithium BMS e penei ana: te matū me te tatau raupapa (hei tauira, 16S LiFePO4), te iahiko tonu me te tirotiro tihi (hei tauira, 100A tonu / 150A tihi), ngā atanga e hiahiatia ana (hei tauira, CAN ki te inverter), me te tikanga taurite (kore mahi mō ngā pūtau hou e ōrite ana). I te mea kua whakaritea aua tawhā e whā, ka tīpakohia e te poari ia ia anō - teAwhe BMS Atamai (Raupapa A)e kapi ana i te awhe katoa 4–24S / 40A–400A, ā, e kapi ana te Raupapa T i te awhe kotahi me te taurite hohe.
Ngā Pātai Auau
Q1Ka taea e te tauira BMS kotahi te kapi i ngā ratonga 4 ki te 24?
Ka hipokina e te Raupapa A te 4–24S mā roto i ngā whirihoranga whānuitanga raupapa e toru (mō LiFePO4: 4–8S, 7–17S, me te 7–24S). I roto i tētahi whirihoranga, ka kitea aunoa te tatau raupapa i roto i te 45 hēkona o te whakakā tuatahi — ka whakamahia e te kete 13S me te kete 16S te papa kotahi me te kore he tatūnga ā-ringa. Ko te painga o te rarangi taonga: e toru ngā whirihoranga e hipokina ana ngā ngaohiko kete mai i te akomanga 12V ki te akomanga 60V me runga ake, hei utu mō tētahi tauira motuhake mō ia ngaohiko.
Q2He aha te rerekētanga i waenga i te taurite kore mahi me te taurite hohe?
Ka tukuna e te taurite kore mahi te utu nui mai i ngā pūtau teitei rawa hei wera, i te 100mA i runga i te Raupapa A — he nui mō ngā pūtau hou kua taurite pai. Ka nekehia e te taurite hohe te pūngao mai i ngā pūtau teitei ki ngā pūtau o raro, tae atu ki te 1A i runga i te Raupapa T — mō ngā kete e tere ake ana te neke o te ōritetanga o ngā pūtau i te mea ka taea e te whakatikatika kore mahi te pupuri, pērā i ngā pūtau kaha-nui, ngā pūtau ora-tuarua rānei.
Q3Me pēhea taku whiriwhiri i waenga i ngā whakatauranga o te au tonu me ngā whakatauranga o te au piki?
Tauwhāitihia te whakatauranga tonu mai i te kukume tonu o te kawenga, ā, manatokohia te whakatauranga tihi ki ngā huihuinga ngaru pēnei i te tīmatanga o te motuka. Me tutuki ngā tirotiro e rua: ka momotu te BMS rahi anake i runga i te ia tonu i te wā o ngā ngaru; ko te rahi anake i runga i ngā tihi ka nui te utu koretake.
