Ngo-2025, ngaphezu kwe-68% yeziganeko zebhetri zombane ezinamavili amabini zilandelelwe kwiiNkqubo zoLawulo lweBattery (BMS), ngokwedatha yeKhomishini yoMbane yeHlabathi. Lo msebenzi wokujikeleza ubaluleke kakhulu ujonga iiseli ze-lithium amaxesha angama-200 ngomzuzwana, zenza imisebenzi emithathu yokugcina ubomi:
1. I-Voltage Sentinel
• I-Overcharge Interception: Ukusika amandla kwi>4.25V/cell (umzekelo, i-54.6V yeepakethi ze-48V) ukuthintela ukubola kwe-electrolyte
• Ukuhlangulwa kwe-Undervoltage: Ukunyanzela imo yokulala kwi-<2.8V/cell (umzekelo, <33.6V yeenkqubo ze-48V) ukuthintela umonakalo ongenakuguqulwa
2. Ulawulo lweDynamic yangoku
| Imeko yomngcipheko | Ixesha lokuPhendula nge-BMS | Iziphumo Zithintelwe |
|---|---|---|
| Ukunyuka kwe-Hill-climbing overload | Umda wangoku ukuya kwi-15A kwi-50ms | Ukudinwa komlawuli |
| Isiganeko esifutshane | Ikhefu lesekethe kwi-0.02s | Ukubaleka kweseli thermal |
3. Ukongamela iThermal ekrelekrele
- 65°C: Ukunciphisa amandla kuthintela ukubila kwe-electrolyte
- <-20 ° C: Utshisa iiseli ngaphambi kokutshaja ukuphepha i-lithium plating
Umgaqo-nkqubo wokuJonga kathathu
① Ubalo lwe-MOSFET: ≥6 ii-MOSFET ezinxuseneyo zibamba i-30A+ yokukhutshwa
② Ulungelelaniso lwangoku: > 80mA inciphisa ukwahlukana kwamandla eseli
③ I-BMS imelana nokungenwa kwamanzi
Uthintelo olubalulekileyo
① Ungaze uhlawule iibhodi ze-BMS eziveziweyo (ukwanda kweengozi zomlilo ngama-400%)
② Kuphephe ukugqitha imida yangoku ("imod yocingo lobhedu" ivala lonke ukhuseleko)
"Ukwahluka kwe-Voltage okudlula i-0.2V phakathi kweeseli kubonisa ukungaphumeleli kwe-BMS ekufutshane," ulumkisa uDkt Emma Richardson, umphandi wokhuseleko we-EV kwi-UL Solutions. Ukuhlolwa kwe-voltage yenyanga ngee-multimeters kunokwandisa ubomi bepakethi nge-3x.
