Ka 2025, ho feta 68% ea liketsahalo tsa betri tsa mabili a mabeli tsa motlakase li ile tsa lateloa ke Battery Management Systems (BMS), ho latela data ea International Electrotechnical Commission. Potoloho ena ea bohlokoa e hlokomela lisele tsa lithium makhetlo a 200 motsotsoana, e etsa mesebetsi e meraro e bolokang bophelo:
1. Sentinel ea Voltage
• Thibelo e Felletseng: E fokotsa matla ho >4.25V/cell (mohlala, 54.6V bakeng sa lipakete tsa 48V) ho thibela ho bola ha electrolyte.
• Pholoso ea Undervoltage: E qobella mokhoa oa ho robala ho <2.8V/cell (mohlala, <33.6V bakeng sa lisebelisoa tsa 48V) ho qoba tšenyo e ke keng ea etsolloa.
2. Dynamic Current Control
| Boemo ba Kotsi | Nako ea Karabelo ea BMS | Liphello Tse Thibeloa |
|---|---|---|
| Boima ba ho hloa leralla | Moeli oa hajoale ho 15A ho 50ms | Ho khathala hoa taolo |
| Ketsahalo ea nakoana | Ho phomola ha potoloho ka 0.02s | Ho baleha ha lisele tsa mocheso |
3. Intelligent Thermal Supervision
- 65 ° C: Phokotso ea matla e thibela ho bela ha electrolyte
- <-20 ° C: Preheats lisele pele li tjhaja ho qoba lithium plating
Molao-motheo oa ho hlahloba Hararo
① Palo ea MOSFET: ≥6 MOSFETs e tšoanang e sebetsana le 30A+ ho tsoa
② Ho leka-lekanya Hona Joale:> 80mA e fokotsa phapano ea matla a lisele
③ BMS e mamella ho kenella ha metsi
Litšitiso Tse Bohlokoa
① Le ka mohla u se ke ua lefisa liboto tsa BMS tse pepesitsoeng (kotsi ea mollo e eketseha ka 400%)
② Qoba ho feta meeli ea hajoale ("copper wire mod" e senya ts'ireletso eohle)
"Phapang ea motlakase e fetang 0.2V pakeng tsa lisele e bontša ho hlōleha ha BMS ho haufi," ho lemosa Dr. Emma Richardson, mofuputsi oa polokeho ea EV ho UL Solutions. Liteko tsa khoeli le khoeli tsa motlakase tse nang le li-multimeter li ka lelefatsa bophelo ba pakete ka 3x.
