Xyoo 2025, ntau dua 68% ntawm cov teeb meem hluav taws xob ob lub log hluav taws xob tau taug qab los cuam tshuam rau Kev Tswj Xyuas Roj Teeb (BMS), raws li International Electrotechnical Commission cov ntaub ntawv. Qhov teeb meem tseem ceeb no saib xyuas cov lithium hlwb 200 zaug hauv ib ob, ua tiav peb txoj haujlwm txuag lub neej:
1. Qhov Voltage Sentinel
• Overcharge Interception: Txiav fais fab ntawm> 4.25V / cell (piv txwv li, 54.6V rau 48V pob) tiv thaiv electrolyte decomposition
• Undervoltage Rescue: Forces pw tsaug zog hom ntawm <2.8V/cell (piv txwv li, <33.6V rau 48V systems) averting irreversible puas
2. Dynamic Current Control
| Risk Scenario | BMS Lub Sijhawm Teb | Qhov Cuam Tshuam Tiv Thaiv |
|---|---|---|
| Toj-nce toj overload | Tam sim no txwv rau 15A hauv 50ms | Controller burnout |
| Kev tshwm sim luv luv | Circuit Court tawg hauv 0.02s | Cell thermal khiav |
3. Intelligent Thermal Saib Xyuas
- 65 ° C: txo hwj chim tiv thaiv electrolyte boiling
- <-20 ° C: Preheats hlwb ua ntej them kom tsis txhob muaj lithium plating
Triple-Check Principple
① MOSFET suav: ≥6 thaum uas tig mus MOSFETs tuav 30A + tawm
② Ntsuas qhov tam sim no:> 80mA txo qis kev muaj peev xwm ntawm tes sib txawv
③ BMS tiv taus dej nkag
Critical Avoidances
① Tsis txhob tsub nqi BMS boards (tshuaj tua hluav taws nce 400%)
② Tsis txhob hla kev txwv tam sim no ("tooj liab hlau mod" voids tag nrho cov kev tiv thaiv)
"Voltage variance tshaj 0.2V ntawm cov hlwb qhia tias yuav ua rau BMS tsis ua hauj lwm," ceeb toom Dr. Emma Richardson, EV kev soj ntsuam kev nyab xeeb ntawm UL Solutions. Kev kuaj xyuas hluav taws xob txhua hli nrog cov ntsuas ntsuas tuaj yeem txuas ntxiv lub neej ntawm 3x.
