Sannadka 2025, in ka badan 68% shilalka baytariyada labada lugood leh ee korantada ah ayaa la raacay Nidaamyada Maareynta Battery-ga (BMS), marka loo eego xogta Guddiga Farsamada ee Caalamiga ah. Wareeggan muhiimka ah wuxuu kormeeraa unugyada lithium 200 jeer ilbiriqsikii, isagoo fulinaya saddex hawlood oo nolosha ah:
1. Voltage Sentinel
• Dhexdhexaadinta Kharashka Xad-dhaafka ah: Wuxuu gooyaa awoodda>4.25V/unugga (tusaale, 54.6V ee baakadaha 48V) isagoo ka hortagaya kala-soocida korantada
Badbaadinta korantada hooseysa: Waxay ku qasbeysaa qaabka hurdada ee <2.8V/cell (tusaale, <33.6V ee nidaamyada 48V) taasoo ka hortageysa burbur aan dib loo celin karin
2. Xakamaynta Dhaqdhaqaaqa ee Hadda
| Muuqaalka Khatarta | Waqtiga Jawaabta BMS | Natiijadii laga hortagay |
|---|---|---|
| Buur-fuulan culeys xad dhaaf ah | Xadka hadda jira ee 15A ee 50ms | Gubashada xakamaynta |
| dhacdo gaaban | Wareegga wareegga ee 0.02s | Kulaylka unugga oo carara |
3. Kormeerka kulaylka caqliga leh
- 65°C: Korontadu waxay ka hortagtaa karkarinta korantada
- <-20°C: Hore ayuu u kululeeyaa unugyada ka hor inta aan la dallacin si looga fogaado dahaadhka lithium
Mabaadi'da-Check Triple
① Tirada MOSFET: ≥6 MOSFETs isbarbar socda ayaa gacanta ku haya 30A+
② Isku dheellitirnaanta Hadda:> 80mA waxay yaraynaysaa kala duwanaanshaha awoodda unugyada
③ BMS waxay u adkeysaneysaa soo gelista biyaha
Ka fogaanshiyaha halista ah
① Waligaa ha dalacsiin looxyada BMS ee qaawan (khatarta dabku waxay korodhay 400%)
② Iska ilaali inaad dhaafto xadeeyayaasha hadda jira
"Farqiga Voltage ee ka sarreeya 0.2V ee u dhexeeya unugyada ayaa muujinaya fashilka BMS ee soo socda," ayaa ka digay Dr. Emma Richardson, cilmi-baadhaha badbaadada EV ee UL Solutions. Jeegaga korantada ee bilaha ah ee leh multimeters waxay kordhin karaan cimriga xirmada 3x.
