Ngo-2025, ngaphezu kuka-68% wezigameko zamabhethri kagesi anamasondo amabili alandelelwe ku-Battery Management Systems (BMS) esengozini, ngokusho kwedatha ye-International Electrotechnical Commission. Lo mjikelezo obalulekile uqapha amaseli e-lithium izikhathi ezingama-200 ngomzuzwana, enze imisebenzi emithathu egcina impilo:
1. I-Voltage Sentinel
• I-Intercharge Overcharge: Inqamula amandla kokuthi >4.25V/cell (isb, 54.6V yamaphekhi angu-48V) ivimbela ukubola kwe-electrolyte
• I-Undervoltage Rescue: Iphoqelela imodi yokulala kokuthi <2.8V/cell (isb, <33.6V yamasistimu angu-48V) igwema umonakalo ongalungiseki
2. I-Dynamic Current Control
| I-Risk Scenario | Isikhathi sokuphendula se-BMS | Umphumela Uvinjelwe |
|---|---|---|
| Ukugcwala kwe-Hill-climbing | Umkhawulo wamanje ku-15A ku-50ms | Ukutubeka kwesilawuli |
| Umcimbi wesifunda esifushane | Ukuhlukana kwesekethe ku-0.02s | Ukugijima kweseli okushisayo |
3. I-Intelligent Thermal Supervision
- 65°C: Ukunciphisa amandla kuvimbela ukubila kwe-electrolyte
- <-20°C: Ishisa kuqala amaseli ngaphambi kokushaja ukuze igweme i-lithium plating
Isimiso Sokuhlola Kathathu
① Ukubala kwe-MOSFET: ≥6 ama-MOSFET afanayo aphatha ukukhishwa okungu-30A+
② Ukulinganisa Kwamanje: >80mA kunciphisa ukuhlukana kwamandla eseli
③ I-BMS imelana nokungena kwamanzi
Ukugwema Okubalulekile
① Ungalokothi ushaje amabhodi e-BMS aveziwe (ingozi yomlilo ikhuphuka ngo-400%)
② Gwema ukweqa imikhawulo yamanje ("imodi yocingo lwethusi" ivala konke ukuvikela)
"Ukuhluka kwamandla kagesi angaphezu kuka-0.2V phakathi kwamaseli kubonisa ukwehluleka kwe-BMS okuseduze," kuxwayisa uDkt. Emma Richardson, umcwaningi wezokuphepha we-EV e-UL Solutions. Ukuhlolwa kwe-voltage yanyanga zonke ngama-multimeters kunganweba isikhathi sokuphila kwephekhi ngo-3x.
