Nk’uko amakuru ya komisiyo mpuzamahanga y’amashanyarazi abitangaza, mu 2025, hejuru ya 68% by’amashanyarazi y’ibiziga bibiri by’amashanyarazi byatewe na sisitemu yo gucunga bateri (BMS). Uru rugendo rukomeye rukurikirana selile ya lithium inshuro 200 kumasegonda, ikora imirimo itatu irinda ubuzima:
1. Umuyoboro wa Sentinel
• Kwishyuza birenze urugero: Kugabanya ingufu kuri> 4.25V / selile (urugero, 54,6V kumapaki 48V) birinda kwangirika kwa electrolyte
• Gutabara Undervoltage: Guhatira uburyo bwo gusinzira kuri <2.8V / selile (urugero, <33.6V kuri sisitemu ya 48V) birinda ibyangiritse bidasubirwaho
2. Igenzura rya none
| Ibyago | Igihe cyo gusubiza BMS | Ingaruka Zirinze |
|---|---|---|
| Kurenza imisozi | Imipaka igezweho kuri 15A muri 50ms | Kugenzura umuriro |
| Ibirori bigufi | Ikiruhuko cyumuzingi muri 0.02s | Akagari ka selile |
3. Kugenzura Ubushyuhe Bwubwenge
- 65 ° C: Kugabanya ingufu birinda electrolyte guteka
- <-20 ° C: Shyushya selile mbere yo kwishyuza kugirango wirinde lithium
Ihame rya gatatu
Kubara MOSFET Kubara: ≥6 parallel MOSFETs ikora 30A + isohoka
Kuringaniza Ibiriho:> 80mA bigabanya ubushobozi bwimikorere ya selile
MS BMS irwanya kwinjira mu mazi
Kwirinda Byingenzi
① Ntuzigere wishyuza imbaho za BMS zerekanwe (inkongi y'umuriro yiyongera 400%)
Irinde kurenga imipaka igezweho ("wire wire mod" ikuraho uburinzi bwose)
Dr. Emma Richardson, umushakashatsi w’umutekano muri EV muri UL Solutions, aragabisha ati: "Impinduka z’umuriro zirenga 0.2V hagati y’utugari zerekana ko BMS iri hafi gutsindwa." Ukwezi kwa voltage kugenzura hamwe na multimetero birashobora kwongerera igihe cyo kubaho kuri 3x.
