Kukweza ukadaulo wotsutsa wa ma gauge amafuta a magalimoto kuti akwaniritse zosowa zenizeni zowunikira magalimoto atsopano amagetsi

2025-03-15

Mu Januwale 2024, malinga ndi DIGITIMES, bungwe lapadziko lonse lapansi Zamagetsi Zamagalimoto Kampani yofufuza za msika, kutumiza kwa pachaka kwa ma resistors amafuta oyezera magalimoto kunafika pa mayunitsi 580 miliyoni, kuwonjezeka kwa chaka ndi chaka kwa 7.2%. Chifukwa cha kufunikira kolondola kwa machitidwe atsopano oyendetsera mabatire amagetsi (BMS), msika ukuyembekezeka kupitirira $930 miliyoni pofika chaka cha 2027, ndi kuchuluka kwa kukula kwa pachaka kwa 6.8%.

Zotsutsa za ceramic zosagwira dzimbiri zakhala zodziwika bwino

Posachedwapa, KOA Group ya ku Japan yatulutsa ma resistors a RN73H series high-precision fuel gauge resistors, omwe amagwiritsa ntchito aluminium nitride ceramic substrates ndi golide-plated electrode technology kuti akwaniritse ± 0.1% resistance drift mu malo okwana -55 ℃ ~ 155 ℃. Kukana kwa dzimbiri la nthunzi ya mafuta ndi kokwera kasanu kuposa zinthu zachikhalidwe. Chogulitsachi chadutsa satifiketi ya AEC-Q200 ndipo chili ndi makina a Nissan e-POWER hybrid. Tathetsa vuto la kulephera kwa masensa amagetsi a thanki yamafuta m'malo otentha kwambiri komanso chinyezi chambiri, "adatero Yusuke Tanaka, Mtsogoleri wa Zaukadaulo wa KOA.

Kuphatikizana mwanzeru kumatsegula njira yatsopano

Kuphatikizika kwa intaneti ya zinthu ndi ukadaulo wa AI kukuyendetsa patsogolo kukweza kwa zotsutsana ndi filimu yokhuthala ya ceramic kuchokera ku zinthu zodziwira chimodzi kupita ku ma module anzeru. Mu Marichi 2024, Bosch ku Germany adatulutsa yankho la "smart resistor" lomwe limaphatikiza ma chips a MCU. Limatha kuwerengera deta ya mulingo wamafuta nthawi yeniyeni ndikuitumiza ku dongosolo la magalimoto kudzera mu CAN bus, ndi chiwopsezo chochepera 0.5%. M'mafakitale, gawo la Honeywell lolimbana ndi dzimbiri la ceramic thick film resistor lagwiritsidwa ntchito ku dongosolo loyang'anira matanki osungira mafuta akunja, ndipo limatha kugwira ntchito mokhazikika kwa maola opitilira 100000 m'malo ovuta kuyambira -55 ℃ mpaka 200 ℃. Zogulitsazi zamtengo wapatali kwambiri zapangitsa kuti phindu lonse la makampaniwa lifike pa 35% -40%, zomwe ndi zokwera ndi 10 peresenti kuposa zinthu zachikhalidwe.

Opanga aku China amagwiritsa ntchito ukadaulo wanzeru wosintha kukana

Mzere watsopano wopangidwa ndi digito wa Dongguan Huake Electronics umayambitsa njira yosinthira kukana kwa laser ya AI, yomwe imawongolera kulondola kwa kukana kwa mita yamafuta kuchokera pa ± 1% mpaka ± 0.5% ndikuchepetsa ndalama zopangira ndi 30%. Zinthu za "Three Defenses" (zosanyowa, zosagwedezeka, zosagwira dzimbiri) zomwe zimapangidwa nazo zalowa mu unyolo woperekera wa Xiaopeng ndi Ideal, ndi chiwongola dzanja chabwino cha malonda cha 99.5% pakugwiritsa ntchito magalimoto. Njira yodziyimira payokha yodziyimira payokha yodziyimira payokha imagwirizana ndi nsanja yamagetsi ya magalimoto ya 12V-800V, "adavumbulutsa Chen Zhiqiang, manejala wamkulu wa kampaniyo.

Yankho lophatikizidwa limathandizira kulowa mwachangu

Makampaniwa akusintha kuchoka pa ma resistors osiyana kupita ku ma modular solutions. Mndandanda waposachedwa wa IHVR womwe watulutsidwa ndi Vishay umaphatikiza ma resistors a gauge yamafuta ndi ma Hall sensors, ndikutumiza deta ya kuchuluka kwamafuta nthawi yeniyeni kudzera mu CAN bus, ndikuwonjezera liwiro la mayankho a dongosolo kufika pa 10ms. Continental Group yatulutsa gawo lanzeru la resistor lomwe lili ndi ntchito yodziwunikira, lomwe limatha kuzindikira kukana kosayenera komwe kumachitika chifukwa cha kuipitsidwa kwamafuta ndikupeza kulondola kwa chenjezo la 95%.

Akatswiri amanena kuti potsatira kukhazikitsidwa kwa muyezo watsopano wa ISO 21498 wowunikira mafuta, zotsutsana ndi mafuta zomwe zimakhala ndi kutentha kwakukulu komanso kuthekera kosinthana deta zidzakhala zofunikira pamsika, ndipo kuchuluka kwa zinthu zanzeru zomwe zikugwiritsidwa ntchito kuyenera kupitirira 40% pofika chaka cha 2025.
