Te Parenga Ngaohiko Hē a te BMS: He aha i tīmata wawe ai, me pēhea te whakatika
Kua whakakorea te parenga o te ngaohiko nui e te BMS. Engari ina tirohia e koe te ngaohiko o te kete — tae noa ki te ngaohiko pūtau toharite — ka pānuihia3.45Vmō ia pūtau, kei raro noa iho i te3.65Vpaepae nui rawa mō te LiFePO4. Te āhua nei kei te hē te whakaoho a te BMS.
Kāore rawa. Kei te aro atu te BMS ki tētahi āhuatanga tūturu — engari ehara i te mea e tirohia ana e koe. Mā te mārama ki ngā mea e aroturukihia ana e te BMS ka mōhio tonu koe ki ngā mea hei tirotiro.
Ngā mea e Aroturukihia ana e te BMS: Ngā Ngaohiko Mō Ia Pūtau, Ehara i te Toharite
Ka whakautu te parenga-ngaohiko BMS kingaohiko pūtau takitahi, kaua ki te ngaohiko kete toharite, ki te ngaohiko kete katoa rānei i wehea ki te maha o ngā pūtau.
Mena he toharite o te kete 16S LiFePO43.45Vmō ia pūtau (katoa55.2V), engari kei te kotahi te pūtau3.66Vko ētahi atu ia he toharite3.44V, ka turakina e te BMS te parenga hiko nui rawa atu i runga i taua pūtau kotahi. Mai i waho, he pai te āhua o te hiko o te kete. Kei te mahi tika te BMS — i kitea he āhua hiko nui rawa atu i runga i te pūtau teitei rawa atu.
Ka tukuna e te BMS te OVP i runga i tēnei pūtau— ahakoa he pai te toharite o te kete
Koinei te tino take o te āhua o te hinganga o te ngaohiko "hē". Ehara i te mea hē. He ngaohiko tūturu kei runga i te pūtau tūturu e rere ana ki runga ake i ōna hoa tata.
Ngā Take e Whā — I Tāutuhia e te Tauira
| Take | Ina hinga | Ngā mea e whakaatuhia ana e te taupānga | Whakatika |
|---|---|---|---|
| Te kore taurite o te pūtau | Tata ki te mutunga o te utunga; kotahi te pūtau kei mua | Kotahi te pūtau teitei; ko ētahi he iti iho | Taurite hohe; huringa taurite katoa |
| He tino tiketike rawa te ngaohiko o te rihi | Ia wāhanga utu i te mutunga | He maha ngā pūtau teitei e whakatata ana ki te OVP | He iti ake te ngaohiko rihi ki ngā whakaritenga mōkihi |
| He iti rawa te paepae OVP i whakatakotoria | I mua ake te kawenga i te mea i tumanakohia | Kei raro rawa ngā pūtau i te 3.65V, engari ka mura te hiko | Tirohia me te whakatika i te paepae BMS |
| Kua hē te whirihoranga o te parenga pāmahana | I roto i ngā taiao wera kei raro i te kawenga | Ka piki te pāmahana o te kete; ka mura te OVP i mua i te parenga pāmahana | Manatokohia ngā paepae tiaki pāmahana |
Take 1: Te Tauritekore o ngā Pūtau (Te Mea Tino Noa)
I te pakeketanga me te huringa o ngā pūtau, ka wehea haeretia rātou e ngā rerekētanga iti o te ātete ā-roto i te wā e utu ana. Ko te pūtau he iti rawa te ātete ka tere te utu, ā, ka tae ki te paepae ngaohiko nui atu i mua i ētahi atu. Ina pā te pūtau kotahi ki te3.65V, ngā haerenga BMS — ahakoa ko te nuinga o te kete kei3.44Vā, ka taea te tango i tētahi utu nui ake.
Me pēhea te whakaū
Whakatuwheratia te taupānga DALY BMS i te wā e utua ana, ka aroturuki i ngā ngaohiko mō ia pūtau. Mena kei te tere ake te pikinga o tētahi pūtau i ētahi atu — me neke whakamua mā te 50–100mV i mua i te taenga atu o ētahi atu ki te taumata3.50V— ko te kore taurite te take.
Me pēhea te whakatika
Mō te kore taurite ngawari (kotahi pūtau 30–50mV i runga ake i ētahi atu): whakahaerehia he wā utu puhoi i te 0.1C, ā, waiho kia hono tonu te kete i muri i te motuhanga o te rihi. Mā tēnei ka whai wā te ara iahiko taurite kore mahi ki te tango i te pūtau teitei i te tihi o te utu.
Mō te kore taurite pumau e hoki wawe mai ana i muri i ia ngana taurite: ko te Smart BMS me te taurite hohe te otinga tika. Ka mahi te taurite hohe puta noa i te huringa utu katoa (ehara i te mea i te tihi o te utu anake), ka tohatoha tonu i te utu i waenga i ngā pūtau kia kore ai te pūtau teitei e tere whakamua i te tuatahi.
Take 2: Teitei Rawa o te Ngaohiko o te Rīhi
Mena ka nui ake te ngaohiko putanga rihi i te ngaohiko utu mōrahi o te kete (pūtau × paepae OVP), ka panaia ngā pūtau ki runga ake i te paepae OVP i ia wātū mā te utu.
Me pēhea te whakaū
Tirohia te ngaohiko putanga rihi mā te whakamahi i te mita ngaohiko. Mō te kete LiFePO4 16S, kaua te putanga rihi e neke atu i te16 × 3.65V = 58.4VKa taea e te rihi hiko 60V te whakaweto i te OVP i ia huringa utunga.
Me pēhea te whakatika
Whakatikatikahia te ngaohiko putanga rihi kia rite ki te whakatakotoranga o te kete, whakakapia rānei te rihi ki tētahi e tika ana te whakatauranga mō te kete. Mō LiFePO4, ko te ngaohiko utu mōrahi noa ko3.65Vmō ia pūtau — hei tauira58.4Vmō te 16S,29.2Vmō te 8S,14.6Vmō te 4S.
Take 3: He iti rawa te taumata OVP
Mena i whirihorahia te BMS i mua me te paepae ngaohiko-rahi - hei tauira,3.55Vhei utu mō3.65Vmō LiFePO4 — ka tūkino te utu noa i te ārai i mua i te kīnga o ngā pūtau.
Me pēhea te whakaū
Tirohia ngā tautuhinga BMS i roto i te taupānga DALY, i te pūmanawa rorohiko o runga rānei. Whakatere ki ngā tautuhinga paepae tiaki, ka manatoko i te paepae tiaki ngaohiko nui ki tō whakatakotoranga matū pūtau.
Me pēhea te whakatika
Whakatikatikahia te paepae OVP kia rite ki te whakaritenga a te kaihanga o tō pūtau mō te ngaohiko utu mōrahi. Mō ngā pūtau LiFePO4 paerewa,3.65Vmō ia pūtau te paerewa mōrahi o te ahumahi.Kaua e whakatakoto kia teitei ake i te whakatakotoranga pūtau— mā te neke atu i te ngaohiko utu mōrahi o te pūtau ka tere ake te hekenga, ā, i ngā wā tino kino, ka mōrearea te haumaru.
Take 4: Kua Whirihoratia Hē te Parenga Pāmahana
I ngā taiao wera — he wāhi kāore i te pai te hauhautanga, he taiao raumati, he huringa tukunga kaha rānei — me tiaki te putea e ngā BMS.pāmahanangā rohe tiaki i mua noa atu i te noho ko te OVP hei pareparenga tika. Mena kei te kite koe i te OVP e hinga ana i roto i ngā āhuatanga wera i te wā kāore anō kia whakamahia te pareparenga pāmahana, tera pea kua hē te whirihoranga, kua monokia rānei ngā paepae pāmahana.
Me pēhea te whakaū
Tirohia te pānui pāmahana i roto i te taupānga BMS i te wā e utu ana ina hinga te OVP. Mena kei te tata atu, kei te nui atu rānei te pāmahana o te kete i te awhe utu kua tūtohutia e te kaihanga pūtau (kei raro iho i te 45°C mō te LiFePO4), me tīmata te tiaki pāmahana - ehara i te OVP. Manatokohia kua whakahohea te paepae tiaki utu pāmahana-tiketike, ā, kua whakatakotoria ki roto i ngā whakaritenga a te kaihanga pūtau.
Me pēhea te whakatika
Whirihorahia te parenga utu pāmahana-tiketike kia mau i mua i te taenga o ngā pūtau ki tētahi pāmahana morearea. Whakapai ake i te hauhautanga o te whare herehere. Kaua e whakaheke i te paepae OVP hei utu mō ngā take wera — ka huna i te raruraru tūturu (wera) ka waiho te kete kia pāngia e te ahotea wera.
Me pēhea te tautuhi anō i muri i ngā haerenga OVP
Ka muku aunoa te parenga ngaohiko nui ina heke te ngaohiko o te pūtau whakaoho i raro i te paepae whakaora OVP (he uara kua whakatakotoria i raro i te pūwāhi haerenga OVP). Ka tupu tēnei i te nuinga o te wā ina:
Kua momotu te rihi— ka heke te ngaohiko pūtau i te memeha haere o te utu mata.
Ka honoa pototia he kawenga— ka heke te ngaohiko o te pūtau teitei.
Ka whakawhiti, ka whakaheke rānei te ara iahiko taurite BMS i te utu mai i te pūtau teitei— ka heke te ngaohiko.
Kaua e ngana ki te tautuhi anō i te BMS ā-ringa, kaua hoki e akiaki kia nui ake te utu. Kei te noho te OVP hei tiaki i te pūtau teitei mai i te nekehia ake i tōna ngaohiko mōrahi. Whakatauhia te pūtake o te take (te kore taurite, te ngaohiko rihi, te tautuhinga paepae, te pāmahana rānei) i mua i te wā utu e whai ake nei.
Me pēhea te āwhina a DALY Smart BMS ki te tautuhi i tēnei
Hei tātaritanga tika i te haerenga OVP me kite i te ngaohiko mō ia pūtau i te wā tonu o te haerenga — he āheinga tēnei e hangaia ana e te DALY Smart BMS.
TeDALY Smart BMSKa whakaatuhia ngā ngaohiko takitahi o ngā pūtau i te wā tūturu. Ina hinga te OVP, ka whakaatuhia e te taupānga ko tēhea pūtau i whakaoho i te reira — kia kitea tonutia ai te pūtake (kotahi pūtau teitei, ngā pūtau teitei katoa, he rerekētanga pāmahana rānei) kaua e whakatauhia i muri i te meka.
Ka tuhia e te rangitaki takahanga hītori te pūtau whakaoho me ngā āhuatanga o ia takahanga OVP, kia taea ai e koe te kī mēnā kei te whakaoho tonu te pūtau kotahi (e tohu ana i te kore taurite tonu) mēnā rānei kei te tae tahi ngā pūtau maha ki te OVP (e tohu ana i te take utu, i te take paepae rānei).
Mō ngā putea he rere tonu te nekehanga,Raupapa Taurite Hoheka neke atu i tētahi taahiraa: hei utu mō te tuku i te utu mai i ngā pūtau teitei mā roto i ngā ātete, ka whakawhiti i te utu i waenga i ngā pūtau puta noa i te huringa utu katoa, kia noho rite tonu te kete i mua i te reihi o tētahi pūtau ki te OVP.
Ngā Pātai Auau
E whakaatu ana te taupānga BMS i te ngaohiko o te kete 56V i runga i te kete 16S — arā, 3.5V te toharite mō ia pūtau. He aha te take e hinga ai te OVP?
Ka pā te paepae OVP kingaohiko pūtau takitahi, ehara i te toharite o te kete. Mena kei te kotahi te pūtau3.66Vko ētahi atu ia he toharite3.48V, ka hinga te OVP i taua pūtau ahakoa te āhua pai o te toharite o te kete. Whakatuwheratia te tirohanga ngaohiko mō ia pūtau i roto i te taupānga — ka kitea te pūtau teitei i runga ake i ētahi atu. Tukuna mai tō whirihoranga kete (ngaohiko pūnaha, tau pūtau, kaha) ki tā mātou tīma, ā, ka taea e mātou te āwhina ki te manatoko mēnā ka whakaratohia e tō BMS o nāianei te tirohanga mō ia pūtau i te hohonutanga e hiahiatia ana e koe.
I whakatikatikahia e au te paepae OVP kia teitei ake hei aukati i ngā haerenga. He haumaru tēnā?
He mea haumaru te whakarerekē i te paepae kia ōrite ki te ngaohiko utu mōrahi tuturu o tō pūtau (mō te LiFePO4 paerewa, koinei3.65Vmō ia pūtau). Te whakatikatika i a iai runga akeKo te whakatakotoranga pūtau hei whakamōkito i ngā haerenga e tohu ana i tētahi raruraru tūturu ehara i te mea koinei — ka taea e ngā pūtau te pana ki runga ake i tō rātou ngaohiko mōrahi, ka tere ake te hekenga, ā, i ngā wā tino kino, ka puta he mōrearea haumaru. Whakatikahia te take matua o ngā haerenga kaua e whakapiki i te paepae ki tua atu i te whakatakotoranga pūtau.
Ko te pūtau kotahi tonu te tuatahi ki te whakaoho i te OVP. Me whakakapi?
Kāore rawa. Ko te pūtau e tae tuatahi ana ki te OVP i te wā e utu ana ko te pūtau he iti rawa te ātete o roto, he iti rawa te kaha e toe ana, he rua rānei - ka kī tonu i te tuatahi.Ko te pūtau me whakakapi ko te mea ka eke ki raro i te ngaohiko i te tuatahii te wā e tukuna ana(te iti o te kaha, te teitei rānei o te ātete i raro i te kawenga), ehara i te mea e tere rawa ana te utu. Hei wehewehe i ēnei, tirohia ngā pito e rua o te huringa i roto i te taupānga BMS: te tihi o te utu mō ngā pūtau OVP-tuatahi, te raro o te tukunga mō ngā pūtau UVP-tuatahi. Mā te taurite hohe ka noho rite te kete ahakoa ko tēhea pūtau ka whakakī tuatahi, ka whakaroa i te hiahia mō te whakakapinga.
He taurite ngoikore, he taurite hohe hoki tā taku BMS — ko tēhea kei te mahi?
Ko te nuinga o ngā waeine Smart BMS paerewa e whakamahi ana i te taurite kore mahi — he iahiko toto iti (te nuinga o te tekau ki te rau mA) ka whakahohe ina whiti te pūtau i te paepae tīmatanga-taurite tata ki te tihi o te utu. Ka whakamahi te raupapa DALY Active Balancing i te whakawhiti utu (te nuinga o te akomanga maha-amp) ā, ka mahi puta noa i te huringa utu, ehara i te mea i te tihi anake. Mō ngā tono taurite ngawari me te utu puhoi, he rawaka te kore mahi. Mō ngā kete e whakaatu ana i te nekehanga tonu i waenga i ngā wā, ko te taurite kaha te ara whakapai ake. Tukuna mai tō kete me tō tauira whakamahinga mō tētahi taunakitanga.
Whakarāpopototanga: Tauira → Take → Whakatika
| Tauira | Take | Whakatika |
|---|---|---|
| Kotahi te pūtau e pā ana ki te OVP; ko ētahi i raro iho | Te kore taurite o te pūtau — ka tere ake te utu o te pūtau kotahi | Ngā wā taurite hohe, ngā wā taurite puhoi rānei |
| Ngā pūtau katoa e whakatata tahi ana ki te OVP | He tino tiketike rawa te ngaohiko o te rihi | He iti ake te putanga rihi kia rite ki ngā whakaritenga mōkihi |
| OVP i te ngaohiko e ahua iti rawa ana | I hē te whakatakoto paepae | Tirohia me te whakatika i te paepae OVP i roto i ngā tautuhinga BMS |
| OVP i ngā taiao wera i te wā e noho puku ana te parenga pāmahana | Kua hē te whirihoranga o te parenga pāmahana | Manatokohia te paepae tiaki utu pāmahana teitei |

Tukuna mai kia whā ngā tau, ā, ka tūtohu mātou i te whirihoranga DALY Smart BMS tika mō tō kete — me te tirohanga mō ia pūtau me te rautaki taurite tika mō tō tauira taurite kore.

Ngā Tuhipoka mō te Maimoatanga Pūtake
Ko te ngaohiko utu mōrahi o te pūtau LFP o te 3.65V/pūtau kua tuhia tonutia puta noa i ngā puna tukutuku motuhake tekau mā tahi kua whakahuatia i runga ake nei (tohutoro 1–11) ā, e ōrite ana ki ngā whakaritenga matua a te kaihanga CATL / EVE / CALB. I kiia tēnei uara he mea kua manatokohia katoatia.
Ko ngā whakaahuatanga o te kaha o roto o te hua (te whakaaturanga mō ia pūtau, te rangitaki hītori, te whanonga taurite) e whakaahuahia ana i runga i te kounga i roto i te tuhinga, kaua ki ngā uara tau motuhake (te tika o te mV, te tere whakahou, te kaha rokiroki-takahanga, ngā whakatauranga o te iahiko taurite), e tatari ana kia whakaūngia aua whakaritenga e te hangarau.
I hangaia te wāhanga Take 4 (Mahana) kia rite ki te whirihoranga hē o te paepae tiaki-mahana, kaua ki te whakawhirinaki tika ki te ngaohiko me te pāmahana, nā te mea kāore ngā tuhinga LFP tūmatanui e tautoko i tētahi whanaungatanga tauanga mārama o te āhua "te pikinga pāmahana X°C → te pikinga ngaohiko pūtau Y mV" i raro i ngā āhuatanga utu. Mā te anga i whiriwhiria i konei ka ārai i ngā kaiwhakamahi kei hē te tautuhi i tētahi take wera hei take ngaohiko.
