Mawu Oyamba
Unduna wa Zamakampani ndi Zaukadaulo ku China (MIIT) posachedwapa udatulutsa muyezo wa GB38031-2025, womwe umatchedwa "chitetezo cholimba kwambiri cha batri," chomwe chimalamula kuti magalimoto onse amphamvu (NEVs) ayenera kukwaniritsa "palibe moto, palibe kuphulika" pansi pamikhalidwe yoipitsitsa pofika pa Julayi 1, 2026126. Apa, tikuwunika zomwe zikufunika zaukadaulo zamabatire komanso kupita patsogolo kofananira ndi Battery Management Systems (BMS) kuti tithane ndi zovutazi.
1. Miyezo Yokwera Yachitetezo cha Mabatire a NEV
Muyezo wa GB38031-2025 umayambitsa ma benchmark okhwima omwe amatanthauziranso chitetezo cha batri:
- Kupewa Kuthawa Kwamatenthedwe: Mabatire amayenera kupirira zochitika zowopsa, kuphatikiza kulowa msomali, kuchulukira, komanso kutentha kwambiri, osapsa ndi moto kapena kuphulika kwa mphindi zosachepera 6016. Izi zimachotsa lingaliro lakale la "nthawi yopulumukira", lomwe limafunikira chitetezo chamkati pa moyo wa batri.
- Kulimbitsa Umphumphu Wamapangidwe: Mayesero atsopano, monga kukana kukhudzidwa kwapansi (kuyerekezera kugunda kwa zinyalala mumsewu) ndi kuwunika kwachitetezo chapambuyo pamalipiro othamanga, kumatsimikizira kulimba muzochitika zenizeni padziko lapansi26.
- Kukwezera Kachulukidwe Kazinthu ndi Mphamvu: Muyezowu umalimbikitsa mphamvu yocheperako ya 125 Wh/kg pamabatire a lithiamu iron phosphate (LFP), kukankhira opanga kuti atenge zida zapamwamba monga zigawo za nano-insulation ndi zokutira za ceramic16.
Zofunikira izi zidzafulumizitsa kuthetseratu opanga otsika kwinaku akuphatikiza kutsogola kwa atsogoleri amakampani monga CATL ndi BYD, omwe matekinoloje awo (mwachitsanzo, CTP 3.0 ya CATL ndi BYD's Blade Battery) ikugwirizana kale ndi machitidwe atsopano26.
2. BMS Evolution: Kuchokera ku Monitoring to Proactive Safety
Monga "ubongo" wamakina a batri, BMS iyenera kusinthika kuti ikwaniritse zomwe GB38031-2025 ziyenera. Makhalidwe akuluakulu ndi awa:
a. Satifiketi Yogwira Ntchito Yapamwamba
BMS iyenera kukwaniritsa mulingo wapamwamba kwambiri wachitetezo chamagalimoto (ASIL-D pansi pa ISO 26262) kuti iwonetsetse kuti ntchito sizikuyenda bwino. Mwachitsanzo, BMS ya m'badwo wachinayi ya BAIC New Energy, yotsimikiziridwa ndi ASIL-D mu 2024, imachepetsa kulephera kwa hardware ndi 90% kupyolera mu kuyang'anira nthawi yeniyeni ndi redundancy design3. Machitidwe oterowo ndi ofunikira kuti azindikire zolakwika msanga komanso kupewa kuthawa kwa kutentha.
b. Kuphatikiza kwa Advanced Sensing Technologies
Njira zochenjezeratu ndi zofunika kwambiri. Masensa a haidrojeni, monga omwe adapangidwa ndi Xinmeixin, amazindikira kutuluka kwa mpweya (mwachitsanzo, H₂) panthawi yotentha kwambiri, kumapereka chenjezo la mphindi 400 pasadakhale. Masensa opangidwa ndi MEMS awa, ovomerezeka pansi pa AEC-Q100, amapereka chidwi chachikulu komanso kukhazikika, zomwe zimapangitsa kuti pakhale njira zotetezera zotsika mtengo, zonyamula katundu5.
c. Cloud-Enabled BMS ndi AI-Driven Optimization
Kuphatikizana kwamtambo kumalola kusanthula kwa data zenizeni zenizeni komanso kukonza zolosera. Makampani monga NXP Semiconductors amathandizira mapasa a digito opangidwa ndi mitambo kuti akonze ma aligorivimu, kuwongolera kuwongolera kwanthawi yayitali (SOC) ndi kulondola kwamalingaliro aumoyo (SOH) ndi 12% 7. Kusinthaku kumathandizira kasamalidwe ka zombo komanso kumathandizira njira zolipirira zosinthika, kukulitsa moyo wa batri.
d. Zopangira Zopanda Mtengo Pakati pa Kukwera kwa Mtengo Wotsatira
Kukwaniritsa miyezo yatsopanoyi kukhoza kuonjezera mtengo wa batri ndi 15-20% chifukwa cha kukweza kwa zinthu (mwachitsanzo, ma electrolyte oletsa moto) ndi kukonzanso kamangidwe2. Komabe, zotsogola monga ukadaulo wa CATL wokhazikika wa CTP komanso makina osavuta owongolera matenthedwe amathandizira kuchepetsa ndalama zomwe zikuwonongeka ndikuwonjezera mphamvu yamagetsi68.
3. Zambiri Zamakampani
l Kukonzanso kwa Chain Chain: Kupitilira 30% yamakampani ang'onoang'ono mpaka apakatikati a mabatire atha kutuluka pamsika chifukwa cha zopinga zaukadaulo ndi zachuma, pomwe mgwirizano pakati pa opanga ma automaker ndi atsogoleri aukadaulo (mwachitsanzo, CATL ndi BYD) adzazama12.
l Cross-Industry Synergies: Kupititsa patsogolo chitetezo m'mabatire a NEV akudutsa muzitsulo zosungiramo mphamvu (ESS), kumene kugwiritsa ntchito grid-scale amafuna zofanana "palibe moto, palibe kuphulika" kudalirika2.
l Utsogoleri Wapadziko Lonse: Miyezo yaku China yatsala pang'ono kukhudza zomwe zikuchitika padziko lonse lapansi, makampani ngati Xinmeixin akutumiza matekinoloje a hydrogen sensor kumisika yapadziko lonse5.
Mapeto
Muyezo wa GB38031-2025 umayimira gawo losintha gawo la NEV la China, pomwe chitetezo ndi zatsopano zimakumana. Kwa opanga mabatire, kupulumuka kumatengera luso la kasamalidwe ka kutentha ndi sayansi yazinthu. Kwa opanga BMS, tsogolo lagona mwanzeru, zolumikizidwa ndi mitambo zomwe zimateteza zoopsa m'malo mochitapo kanthu. Pamene makampani akusintha kuchoka ku "kukula kulikonse" kupita ku "chitetezo choyamba", makampani omwe amaphatikiza mfundozi mu DNA yawo adzatsogolera nthawi yotsatira ya kuyenda kosatha.
Khalani tcheru kuti mudziwe zambiri zokhudza kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.
