He mahi hē te kore e tiakina te pākahiko LiFePO4 kāore he BMS.
Ka taea e te utu nui kotahi te whakangaro i ngā pūtau mō ake tonu atu. Ko te BMS hē
ka puta he maha ngā marama o ngā tapahi wairua me te maumauria o te kaha. Ko tēnei aratohu
e hipoki ana i ngā mea katoa e hiahiatia ana e koe hei whakatau tika.
E toru ngā mahi a te BMS i te wā kotahi:
Te TiakitangaKa tapahia te ara iahiko i te wā tonu ka hipa te pūtau i tōna matapihi haumaru — te utu kei runga ake i te 3.65 V/pūtau, te tukunga kei raro iho i te 2.8 V/pūtau (te paepae whakahaere e taunakitia ana), ina rānei ka mōrearea ngā āhuatanga o te iahiko, te pāmahana, te ara iahiko poto rānei.
Te tauriteka whakatika i te nekehanga maori i waenga i ngā pūtau takitahi i roto i ngā rau huringa. Ki te kore, ko tō pūtau ngoikore rawa te mea e whakatau ana i te kaha whakamahi katoa o tō kete — ā, ka tere rawa te pirau.
AroturukiKa aroturuki i te āhua o te utu (SOC), te āhua o te hauora (SOH), te ngaohiko mō ia pūtau, te pāmahana, me te tatau huringa i te wā tūturu. Mā tēnei raraunga ka taea e koe te hopu i tētahi pūtau e hinga ana i mua i te tango i te kete.
Ko te pihi tukunga papatahi ahurei o LiFePO4 e hiahia ana ki tētahi BMS motuhake ki te matū. Ka hē te pānui a te BMS whānui i te SOC puta noa i te papatahi katoa, ā, ka puta he tapahi ngaohiko iti teka me te kaha nui e toe ana.
Me pēhea te rahi o tō BMS
Me tino ōrite ngā āhuatanga e rua ki tō kete.
Hipanga 1 — Ngaohiko (tau pūtau raupapa).Me whai BMS 4S te kete 4S. Me whai BMS 16S te kete 16S. Ka puta he hē o te pānui ngaohiko nā te motu kotahi o te pūtau, ā, ka kore e pono te tiakitanga.
| Whirihoranga | Ngaohiko Ingoa | Ngaohiko Utu Mōrahi | Te Whakamahinga Noa |
|---|---|---|---|
| 4S | 12.8 V | 14.6 V | RV, moana, kore-whatunga |
| 8S | 25.6 V | 29.2 V | Ngā motuka whakatere, te hiko pūngao rā 24V |
| 16S | 51.2 V | 58.4 V | Putunga taonga kāinga, kāreti korowha |
| 24S | 76.8 V | 87.6 V | 72V EV, ahumahi |
Hipanga 2 — Onāianei.Wehea te kawenga tonu mōrahi ki ngā watts mā te ngaohiko o te kete, kātahi ka tāpirihia te tawhē haumaru 25–30%.
5,000 W ÷ 48 V = 104 A → Tīpakohia he BMS 150 AKaua rawa e whakahaere i tētahi BMS i te 100% o tōna iahiko whakatauranga. Ka pana tonu te hiahia o te ao tūturu ki runga ake i te whika kua tatauhia e te whakahekenga wera me ngā kawenga ngaru.
Taurite Kaha, Taurite Korekore rānei
Taurite kore mahika moumou i te utu nui hei wera mā roto i tētahi ātete (50–200 mA). Ka pupuri i ngā putea e ōrite ana kia rite engari kāore e taea te whakahoki mai i te nekenekehanga nui o te pūtau — ko te whakatika i te kore taurite 500 mAh e 5 hāora pea i te 100 mA.
Taurite hoheKa whakawhiti i te pūngao i waenga i ngā pūtau mā roto i tētahi ara iahiko inductor-capacitor (1–5 A, te pai o te 80–95%). Ka whakatikahia te taurite kore 10–50× tere ake, ā, ka mahi puta noa i te huringa utu me te tukunga katoa, ehara i te mea i te tihi anake.
| Horopaki | Ātaahua | Hohe |
|---|---|---|
| Ngā pūtau kotahi-rōpū, ≤ 0.3C te huringa | Rawaka | Whakapainga iti |
| Kete ≥ 200 Ah, te huringa hohonu o ia rā | Ngā Pakanga | I tūtohutia |
| Te tere tukunga > 0.5C tonu | Kāore e taea te whai | E hiahiatia ana |
| Ngā pūtau whakauru, ngā pūtau kua pakeke rānei | Kāore e taea te whakaora | Ka taea te whakaora i te kete |
Kōwhiria te kore mahimō ngā pūtau kotahi-rōpū e hurihia ana i te ≤ 0.3C.
Kōwhiria te hohemō ngā kete ≥ 200 Ah, ngā reiti tukunga neke atu i te 0.5C, ngā pūtau rānei mai i ngā puranga whakauru.
Rārangi Arowhai Kōwhiringa Taurangi-Whā
I mua i te tono, manatokohia ngā taurangi e whā i te wā kotahi:
| Taurangi | Whakaritenga |
|---|---|
| Te maha o ngā raupapa | He tino ōrite ki tō whirihoranga pūtau |
| Auaha tonu | Kawenga mōrahi (W) ÷ ngaohiko (V) + tawhē 25–30% |
| Ngā Āhuatanga | Nihokikorangi (katoa) · RS485/CAN (rā) · Taurite hohe (≥ 200 Ah) |
| Matū | Whakaūtia te whirihoranga paepae LFP/LiFePO4 |
Ka hipokina e ngā waeine BMS DALY Energy te 4S ki te 24S me te 10 A ki te 500 A, i roto i ngā whirihoranga paerewa, atamai (Nihokikorangi + RS485/CAN), me te taurite hohe — ka tukuna katoatia me ngā paepae matū LFP hei taunoa.
