A cikin 2025, sama da kashi 68% na abubuwan da suka faru na baturi mai kafa biyu na lantarki sun samo asali ne daga Tsarin Gudanar da Batir (BMS), bisa ga bayanan Hukumar Lantarki ta Duniya. Wannan mahimmancin kewayawa yana lura da ƙwayoyin lithium sau 200 a cikin sakan daya, yana aiwatar da ayyuka uku na kiyaye rayuwa:
1. Voltage Sentinel
• Tsararru mai yawa: Yana yanke wuta a> 4.25V/cell (misali, 54.6V don fakitin 48V) yana hana bazuwar electrolyte
• Cikakken tserewa: tilasta yanayin bacci a <2.8V / Cell (misali, <33v don tsarin 48v)
2. Sarrafa Tsarukan Yanzu
| Halin haɗari | Lokacin Amsa BMS | An Hana Sakamakon |
|---|---|---|
| Yin hawan tudu | Iyaka na yanzu zuwa 15A a cikin 50ms | Ƙunƙarar mai sarrafawa |
| Taron gajeriyar hanya | Watsewar kewayawa a cikin 0.02s | Guduwar thermal cell |
3. Kula da thermal mai hankali
- 65°C: Ragewar wuta yana hana tafasar electrolyte
- <-20°C: Yana yin zafi da sel kafin yin caji don guje wa platin lithium
Ƙa'idar Duba Sau Uku
① MOSFET Count: ≥6 daidaitattun MOSFETs suna ɗaukar fitarwa 30A+
② Daidaita Halin Yanzu:> 80mA yana rage girman bambance-bambancen iyawar salula
③ BMS yana jure shigar ruwa
Kaucewa Mahimmanci
① Kar a taɓa cajin allon BMS da aka fallasa (haɗarin wuta yana ƙaruwa 400%)
② Guji ƙetare iyakokin na yanzu ("Copper waya mod" ya ɓata duk kariya)
"Bambancin wutar lantarki da ya wuce 0.2V tsakanin sel yana nuna gazawar BMS mai zuwa," in ji Dokta Emma Richardson, mai binciken aminci na EV a UL Solutions. Binciken wutar lantarki na wata-wata tare da multimeters na iya tsawaita tsawon fakitin da 3x.
