Mu 2025, kupitilira 68% yamagetsi amagetsi amagetsi awiri adachokera ku Battery Management Systems (BMS), malinga ndi data ya International Electrotechnical Commission. Madera ovutawa amawunika ma cell a lithiamu maulendo 200 pa sekondi iliyonse, ndikuchita ntchito zitatu zopulumutsa moyo:
1. Mphamvu ya Voltage Sentinel
• Kuthira Chachakudya Chowonjezera: Kumadula mphamvu pa> 4.25V/selo (monga 54.6V ya 48V mapaketi) kuteteza kuwonongeka kwa electrolyte
• Kupulumutsidwa kwa Undervoltage: Imakakamiza kugona pa <2.8V/selo (monga <33.6V ya makina a 48V) kuletsa kuwonongeka kosasinthika
2. Dynamic Current Control
| Zowopsa | Nthawi Yoyankha BMS | Zotsatira Zaletsedwa |
|---|---|---|
| Phiri-kukwera mochulukira | Malire apano mpaka 15A mu 50ms | Kutopa kwa Controller |
| Chochitika chachifupi | Kuthamanga kwa kuzungulira mu 0.02s | Kuthamanga kwa ma cell matenthedwe |
3. Intelligent Thermal Supervision
- 65 ° C: Kuchepetsa mphamvu kumalepheretsa kuwira kwa electrolyte
- <-20 ° C: Imatenthetsa ma cell musanalipire kuti mupewe plating ya lithiamu
Mfundo Yoyang'ana Katatu
① Kuwerengera kwa MOSFET: ≥6 MOSFETs yofananira imagwira 30A+ kutulutsa
② Kuyanjanitsa Pakalipano:> 80mA imachepetsa kusiyanasiyana kwa ma cell
③ BMS imalimbana ndi kulowa kwa madzi
Zopewa Zovuta
① Osalipira matabwa a BMS owonekera (chiwopsezo chamoto chikuwonjezeka 400%)
② Pewani kudutsa malire apano ("copper wire mod" imasokoneza chitetezo chonse)
"Kusiyanasiyana kwamagetsi kupitirira 0.2V pakati pa maselo kumasonyeza kulephera kwa BMS," akuchenjeza Dr. Emma Richardson, wofufuza za chitetezo cha EV ku UL Solutions. Kuwunika kwamagetsi pamwezi ndi ma multimeter kumatha kukulitsa moyo wapaketi ndi 3x.
