Muna 2025, anopfuura makumi matanhatu nesere muzana emagetsi maviri-mavhiri ebhatiri zviitiko zvakateedzerwa kune yakakanganiswa Battery Management Systems (BMS), maererano neInternational Electrotechnical Commission data. Iyi dhizaini yakakosha inotarisisa lithium masero ka200 pasekondi, ichiita mabasa matatu ekuchengetedza hupenyu:
1. Voltage Sentinel
• Overcharge Interception: Inocheka simba pa>4.25V/cell (eg, 54.6V ye48V packs) kudzivirira kuora kwe electrolyte
• Undervoltage Rescue: Inomanikidza kurara pa <2.8V/cell (eg, <33.6V ye48V masisitimu) kudzivirira kukuvara kusingadzoreki.
2. Dynamic Current Control
| Risk Scenario | BMS Mhinduro Nguva | Mhedzisiro Inodzivirirwa |
|---|---|---|
| Chikomo-kukwira overload | Muganho wazvino kusvika ku15A mu50ms | Controller kuneta |
| Short-circuit chiitiko | Kupwanya kwedunhu mu0.02s | Cell thermal runaway |
3. Intelligent Thermal Supervision
- 65°C: Kuderedza simba kunodzivirira kufashaira kwe electrolyte
- <-20 ° C: Inopisa masero isati yachaja kudzivirira lithium plating
Triple-Check Principle
① MOSFET Count: ≥6 yakafanana MOSFETs inobata 30A+ kubuda
② Kuenzanisa Ikozvino:> 80mA inoderedza kupatsanurwa kwesero
③ BMS inomira mukati memvura
Nzvenga Dzakakosha
① Usambochaja mabhodhi akafumurwa eBMS (ngozi yemoto inowedzera 400%)
② Dzivisa kunzvenga miganho yazvino ("copper waya mod" inobvisa dziviriro yese)
"Voltage musiyano inopfuura 0.2V pakati pemasero inoratidza kukundikana kweBMS kwava pedyo," anonyevera Dr. Emma Richardson, EV kuchengetedza muongorori paUL Solutions. Monthly voltage cheki ine multimeter inogona kuwedzera hupenyu hwepaki ne3x.
