Nhanganyaya
China's Ministry of Industry and Information Technology (MIIT) nguva pfupi yadarika yakabudisa GB38031-2025 standard, inonzi "strictest battery safety mandate," iyo inorayira kuti motokari itsva dzose dzemagetsi (NEVs) dzinofanirwa kuwana "hapana moto, hapana kuputika" pasi pemamiriro ezvinhu akanyanya kusvika July 1, 2026126. Uyu mutemo wakasiyana-siyana unoisa chiratidzo chekuchengeteka, kusingatarisirwi kunokosha. Pano, isu tinoongorora zvirikuitika zvehunyanzvi zvinoda mabhatiri uye kufambira mberi kunoenderana muBattery Management Systems (BMS) kusangana nematambudziko aya.
1. Yakakwirisa Mitemo Yekuchengetedza yeNEV Mabhatiri
Iyo GB38031-2025 yakajairwa inosuma mabhenji akaomesesa anotsanangurazve kuchengetedza kwebhatiri:
- Thermal Runaway Prevention: Mabhatiri anofanirwa kumirisana nemamiriro akanyanya, anosanganisira kupinzwa kwembambo, kuwandisa, uye kuratidzwa kwekushisa kwakanyanya, pasina kubata moto kana kuputika kweinenge 60 maminetsi16. Izvi zvinobvisa iyo yapfuura "nguva yekupukunyuka" pfungwa, ichida kuchengetedzwa kwemukati mukati mehupenyu hwebhatiri.
- Kuwedzeredzwa Kwechimiro Chekutendeseka: Miedzo mitsva, senge pasi pesimba kuramba (kutevedzera kudhumhana kwemarara emumugwagwa) uye mushure mekukurumidza-chaji kutenderera kutenderera kuongororwa, inova nechokwadi chekusimba mumamiriro epasirese26.
- Material and Energy Density Upgrades: Iyo chiyero inosimbisa hushoma simba density ye125 Wh/kg yemabhatiri e lithium iron phosphate (LFP), ichisunda vagadziri kuti vatore zvinhu zvepamberi senge nano-insulation layers uye ceramic coatings16.
Izvi zvinodikanwa zvino mhanyisa kubviswa kwevagadziri vakaderera-tier uku vachibatanidza hutongi hwevatungamiriri veindasitiri vakaita seCATL neBYD, vane matekinoroji (semuenzaniso, CATL's CTP 3.0 uye BYD's Blade Battery) yatoenderana nemaitiro matsva26.
2. BMS Evolution: Kubva Kutarisisa kuenda Kuchengetedzo Yekuita
Se "uropi" hwemabhatiri masisitimu, BMS inofanirwa kushanduka kuti isangane neGB38031-2025 zvinotarisirwa. Mafambiro akakosha anosanganisira:
a. Yepamusoro Functional Safety Certification
BMS inofanirwa kuwana yepamusoro-soro kuchengetedzwa kwemotokari nhanho (ASIL-D pasi pe ISO 26262) kuve nechokwadi chekutadza-kuchengetedza mashandiro. Semuenzaniso, BAIC New Energy yechizvarwa chechina BMS, yakasimbiswa ASIL-D muna 2024, inoderedza mitengo yekutadza kwehardware ne90% kuburikidza nekutarisa-chaiyo-nguva uye redundancy dhizaini3. Masisitimu akadaro akakosha pakuona kukanganisa kwekutanga uye kudzivirira kutiza kwekupisa.
b. Kubatanidzwa kweAdvanced Sensing Technologies
Nzira dzekutanga dzekunyevera dzakakosha. Masensa eHydrogen, akadai seaya akagadzirwa neXinmeixin, anoona kubuda kwegasi (semuenzaniso, H₂) panguva yekutanga-nhanho yekupisa yekupisa, ichipa kusvika ku400 maminetsi yekuyambira. Aya maMEMS-based sensors, akasimbiswa pasi peAEC-Q100, anopa kunzwisiswa kwakanyanya uye kusimba, achigonesa kudhura, kurongedza-level kuchengetedza mhinduro5.
c. Cloud-Enabled BMS uye AI-Inofambiswa Nekugadzirisa
Cloud kubatanidzwa kunobvumira chaiyo-nguva yekuongorora data uye kufungidzira kuchengetedza. Makambani akaita seNXP Semiconductors anowedzera makore-based digital twins kuti agadzirise algorithms, kuvandudza mamiriro-e-charge (SOC) uye mamiriro-ehutano (SOH) estimation accuracy ne12% 7. Iyi shanduko inokwidziridza manejimendi ezvikepe uye inogonesa adaptive yekuchaja nzira, kuwedzera hupenyu hwebhatiri.
d. Zvigadzirwa Zvinodhura Pakati Pekukwira Kwemitengo Yekuteerera
Kuzadzikisa zviyero zvitsva zvinogona kuwedzera mutengo webhatiri ne15-20% nekuda kwekuvandudzwa kwezvinhu (semuenzaniso, maelectrolyte anodzosa moto) uye zvimiro zvekare2. Nekudaro, hutsva hwakaita seCATL's modular CTP tekinoroji uye yakareruka yekudziya manejimendi masisitimu anobatsira kudzikisira mari uchiwedzera simba density68.
3. Yakakura Indasitiri Zvinoreva
l Supply Chain Reshaping: Pamusoro pe30% yemafemu madiki-kusvika-epakati-mabhatiri anogona kubuda pamusika nekuda kwehunyanzvi uye zvipingamupinyi zvemari, ukuwo kubatana pakati pevagadziri vemotokari nevatungamiriri vetekinoroji (semuenzaniso, CATL neBYD) kuchadzika12.
l Cross-Industry Synergies: Kufambira mberi kwekuchengetedza mumabhatiri eNEV kuri kududzira mumasisitimu ekuchengetedza simba (ESS), uko grid-scale application inoda zvakafanana "hapana moto, hapana kuputika" kuvimbika2.
l Hutungamiri Hwepasi rose: Zviyero zveChina zvakagadzirira kupesvedzera tsika dzepasirese, nemakambani akaita seXinmeixin achiendesa kunze hydrogen sensor tekinoroji kumisika yepasi rose5.
Mhedziso
Iyo GB38031-2025 chiyero inomiririra shanduko yechikamu cheChina NEV chikamu, uko kuchengetedzeka uye hunyanzvi zvinosangana. Kune vanogadzira mabhatiri, kupona kunotsamira pakuziva manejimendi ekupisa uye sainzi yezvinhu. Kune vanogadzira BMS, ramangwana riri muhungwaru, makore-akabatana masisitimu anodzivirira njodzi pane kuita kwadziri. Sezvo indasitiri inoshanduka kubva pa "kukura pane zvese" kuenda kune "chengetedzo-yekutanga" hunyanzvi, makambani anoisa aya masikirwo muDNA yavo achatungamira nguva inotevera yekufamba kwakasimba.
Ramba wakarongedzerwa kuti uwane mamwe magadzirirwo ezvekufambiswa kwemitemo uye yekucheka-kumucheto matekinoroji anoumba ramangwana remagetsi matsva emotokari.
Nguva yekutumira: Kubvumbi-22-2025
