Vagadziri VeMotokari Yemagetsi Yekubatanidza Vagadziri Vanowana Sei Tekinoroji Kubudirira muMiniaturization uye Yakakwira Yazvino Kugona?

Indasitiri yemotokari iri kuita shanduko huru, inotungamirwa nekukwira kwemotokari dzemagetsi (EVs), advanced driver-assistance system (ADAS), uye matekinoroji akabatana. Pamwoyo wekushanduka uku kune magetsi ekubatanidza, ayo anoshanda seakakosha malink ekugovera simba, kufambisa data, uye chiratidzo chechiratidzo mukati memotokari. Sezvo mota dzichiwedzera kuve nemagetsi uye nekuzvimiririra, kudiwa kwezvibatanidza izvo zvese zviri madiki-kuchengetedza nzvimbo uye kuderedza huremu-uye inokwanisa kubata mamhepo akakwira-kusvika ku700A kana kupfuura yekuchaja nekukurumidza uye masystem-akasimba-yakawedzera. Izvi zviviri zvinodikanwa zvinounza akakosha einjiniya matambudziko, sezvo hukuru hudiki hunowanzo kanganisa manejimendi ekupisa uye yazvino-yekutakura kugona, izvo zvinogona kutungamira mukupisa, kutadza, kana kudzikisira kugona.

Zvichiitika, zvinobatanidza mota dzaive dzakakura kuti dzikwanise kushanyirwa nemagetsi akakwira, asi shanduko yakanangana nemacompact architectures muEVs uye mahybrid emagetsi mota (HEVs) inoda hunyanzvi. Semuyenzaniso, EV yemazuvano ingada majoikirini anokodzera munzvimbo dzakasimba mukati memabhatiri mapaketi uku uchibata magetsi anosvika 1,000V uye mafungu anodarika 400A. Vagadziri vakaita seTE Kubatana, Aptiv, Molex, uye Amphenol vari pamberi pezvinobudirira izvi, kusimudzira zvinhu zvepamberi, dhizaini dhizaini, uye hunyanzvi hwekugadzira hunyanzvi hwekuyananisa izvi zvinopokana zvinoda. Zvinoenderana nekufanotaura kweindasitiri, musika wepasi rose wemotokari yekubatanidza unotarisirwa kukura paCAGR yeinopfuura 8% kusvika 2030, uchikurudzirwa nemaitiro emagetsi. Mitsva inonangana nekusimudzira kusimba kwazvino, kuvandudza kuparara kwemafuta, uye kuve nechokwadi chekuvimbika munzvimbo dzakaoma, senge vibrations kusvika kuSG4 mazinga uye tembiricha kubva -40°C kusvika 170°C.

Ichi chinyorwa chinoongorora budiriro yehunyanzvi inogonesa kufambira mberi uku. Nekuongorora mazano akakosha, mienzaniso chaiyo yechigadzirwa, uye zvinorehwa neramangwana, tinopa ruzivo kune mainjiniya, maOEM, uye vane chekuita nemabatiro aya. vagadziri vemotokari dzemagetsi ekubatanidza kuwana miniaturization pasina kupa hukuru hwekutakura ikozvino. Munguva iyo kudzikisa huremu hwemotokari kunogona kuwedzera EV chiyero ne5-10%, uye nekukurumidza kuchaja kunoda simba rekubata simba, izvi zvinobudirira hazvisi zvehunyanzvi zvehunyanzvi asi zvakakosha pakufamba kwakasimba.

The Dual Challenge: Miniaturization vs. High Current-Carrying Capacity

Kuwana miniaturization mumotokari dzemagetsi ekubatanidza uku uchichengetedza kana kusimudzira yakakwirira-yekutakura-inotakura huwandu kunosanganisira kukunda inherent trade-offs. Miniaturization inoderedza saizi yekubatanidza, pitch (chinhambwe pakati pepini), uye chitsiko chetsoka, izvo zvakakosha pakubatanidza mamwe magetsi munzvimbo shoma dzemotokari. Semuyenzaniso, kudzikisira pitch pitch kubva pa2.54mm kusvika 1.27mm kunogona kutapudza tsoka dzePCB kusvika pa78%, zvichibvumira denser component kurongedza mumamodule semabhatiri ekutonga masisitimu (BMS) kana infotainment units. Zvisineyi, hukuru hudiki hunowedzera nyaya sekuwedzera kuramba kwemagetsi, kupisa kwemoto, uye kushaya simba kwemuchina, kunyanya kana uchibata mamhepo akakwira anodiwa paEV propulsion kana 48V mild-hybrid system.

Yakakwira ikozvino-inotakura simba inoda kushomeka kwekubata kuramba (kazhinji <10 mΩ) kuderedza kurasikirwa kwemagetsi uye kugadzirwa kwekupisa, semutemo weOhm (P = I²R). Mumagadzirirwo echinyakare, nzvimbo dzakakura dzekusangana uye zvinhu zvakakora zvakashandiswa kubata izvi, asi miniaturization inodzika sarudzo idzi. Thermal management inova yakakosha; kupisa kwakanyanya kunogona kukanganisa kuvharisa, kukonzera arcing, kana kutungamira mukutadza pasi pemitemo yemotokari seLV214 kana USCAR. Pamusoro pezvo, high-voltage applications (kusvika ku1,000V) muEVs inounza njodzi dzekukanganiswa kwemagetsi (EMI) uye kuburitsa chikamu, zvichidikanwa dhizaini dzakavharidzirwa, dzakavharwa dzinowedzera kuwanda-kuverengera kuita miniaturization.

Zvinhu zvezvakatipoteredza zvinosanganisa matambudziko aya: zvinobatanidza zvinofanirwa kushingirira kuzunguzika (semuenzaniso, Kirasi 2 kana SG4), tembiricha yakanyanyisa (-40°C kusvika 150°C), uye ingress dziviriro (IP67/IP69K) yekuvimbika mu under-hood kana chassis application. Zvishandiso zvakaita semhangura alloys, nepo conductive, inogona kunge isingakwani mune miniaturized mafomu nekuda kwe creepage uye clearance zvinodiwa kune yakakwira voltage. Zvitsva mumaturusi ekuedzesera, senge finite element analysis (FEA) yemhando yekupisa, inobatsira kufanotaura kuita, asi mabudiro chaiwo epasirese anovimba nekufunga patsva nzvimbo dzekuonana, zvekushandisa, uye zvivakwa. Sezvo mota dzichibatanidza mamwe ma sensors uye actuators-anofungidzirwa kudarika 1,500 waya pamotokari panosvika 2025-kudiwa kwehuremu, masimba emagetsi epamusoro-soro anowedzera, kusundira vagadziri kune mhinduro dzakasanganiswa dzinobatanidza simba, chiratidzo, uye data mune compact mafomu.

Kubudirira mune Zvishandiso uye Dhizaini Magadzirirwo

Kuenzanisa miniaturization uye yakakwirira ikozvino kugona, vagadziri vakapayona zvepamberi zvinhu uye maitiro ekugadzira. Mapolymer akakwira-performance senge polybutylene terephthalate (PBT), liquid crystal polymer (LCP), uye polyphthalamide (PPA) inopa kugadzikana kwekupisa kusvika 170 ° C uku ichigonesa madziro matete uye madiki edzimba. Zvishandiso izvi zvinotsiva simbi dzinorema, zvichidzikisa huremu kusvika 78% zvichienzaniswa nemaitiro echinyakare, uye zvinosanganisira zvinhu zvakaita sekuvhara kwakanaka uye kusununguka kwekunetseka kwekudzivirira kuzunguzika.

Mukugadzirisa dhizaini, mabudiro akaita seRADSOK® tekinoroji inoshandisa hyperbolic grid mapatani kuti iwedzere nzvimbo, ichibvumira yakakwira currents (200-700A) mumakompakiti mafomati pasina kuenzana saizi inowedzera. Saizvozvo, tekinoroji yekuonana yakananga inobvisa zvitubu zvepakati, kuderedza kuramba uye kugonesa scalability ku400A pa1,000V. Multi-functional terminals (MFTs) inobatanidza simba uye mapini echiratidzo mumatanda akakomba (eg, 1.8mm), kuderedza crosstalk kuburikidza nekunatsiridza nhovo uye nano-coatings iyo inosimudzira conductivity uye corrosion kuramba.

Thermal manejimendi magadzirirwo anosanganisira akakwenenzverwa geometries ekufambisa kwemhepo, kupisa-kubvisa zvimbi, uye zvinhu zvine high thermal conductivity (> 200 W/mK). Semuenzaniso, kushandisa zviteshi zvemhangura yakachena pachinzvimbo chealloys zvinodzikisira kuramba, kuwedzera hupenyu neka100 uye kutsigira ultrasonic welding yekumisa kwakavimbika. Modular dhizaini inobvumira kuchinjika mapango (2-3 maconta) uye maratidziro (yakatwasuka/kurudyi-kona), inokodzera akasiyana eEV zvivakwa uku uchichengetedza IP67 chisimbiso.

Simulation uye kufambira mberi kwekuyedza, senge AI-inotyairwa FEA, inomhanyisa kusimudzira, kuve nechokwadi chekuti majoini anosangana nemayero akaita seISO 16750 yevibration uye ECE R100 yeEVs. Izvi zvinobudirira hazvigadzirise kusawirirana chete asi zvinowedzera kushanda zvakanaka; semuenzaniso, kureba kwakaderedzwa crimp (55% ipfupi) kurerutsa kusangana, kutema mitengo uye kugonesa kugadzirwa kweotomatiki mukugadzira-vhoriyamu.
