China EV Kuchaja PCB Kugadzira uye Gungano

Highleap Electronics inopa yakazara PCB yekugadzira uye magungano ekugadzirisa mukati memotokari, maindasitiri, nharembozha, uye simba zvikamu. EV yekuchaja maPCB anomiririra imwe yehunyanzvi hwedu hunoda hunyanzvi, uko hombe kubata kwemagetsi kunosangana nemotokari kuvimbika zviyero. Sezvo mota dzemagetsi dzichichinja zvekufambisa, tinogadzira mabhodhi ekuchaja ezvivakwa zvinosimbisa shanduko iyi.

Heavy Copper EV Kuchaja maPCB ePamusoro Yazvino

EV kuchaja maPCB anofanirwa kumirisana nezvinodiwa zvazvino uno kupfuura zvemagetsi zvakajairika. Ultra-nekukurumidza machaja anosvika 350kW anogona kuendesa anopfuura mazana mashanu amps, ayo akajairwa 1-2oz mabhodhi emhangura haagone kutsigira. Kuve nechokwadi chekushanda kwakachengeteka uye kwakavimbika, EV kuchaja PCBs shandisa
inorema mhangura PCB tekinoroji kusvika ku10-20oz, ichigonesa kugadzikana kwemagetsi pasina kupisa.

KuHighleap Electronics, maitiro edu ekugadzira maPCB ekuchaja eEV—akavakirwa pahunyanzvi hwepamusoro hwekugadzira maPCB —anovimbisa kudzora ukobvu hwemhangura, kugoverwa kwemagetsi kwakagadziridzwa, uye ma thermal vias akasimba. Matekiniki aya anodzivirira nzvimbo dzinopisa uye anovimbisa kugara kwenguva refu, zvichiita kuti maPCB edu ekuchaja eEV ave hwaro hwakavimbika hwemasisitimu ekuchaja ane simba guru.

Thermal Management muEV Kuchaja maPCB

Kuvimbika kwemafuta chinhu chinotsanangura muEV kuchaja PCB dhizaini. Kunyangwe pa95% kunyatsoshanda, 150kW DC inokurumidza charger inogadzira akati wandei kilowatts ekupisa iyo inofanirwa kuramba ichiraswa. Kusiyana nezvinogadzirwa nevatengi, maEV majaja anomhanya siku nesikati munzvimbo dzekunze kubva -40°C kusvika +50°C.

Isu mainjiniya maEV ekuchaja maPCB ane zvigadziriso zvemhando yepamusoro zvinosanganisira mavias akazadzwa nemhangura, akagadziridzwa kuburikidza nearrays, uye sarudzo yesimbi-core substrates yemhando yepamusoro yekupisa. Kune ekupedzisira-yepamusoro-simba majaja ari pamusoro pe100kW, isu tinobatanidza mvura inotonhorera nzvimbo uye tembiricha yekutarisa kuti ive nechokwadi chekushanda kusingapindiki. Aya maitiro ekugadzira anoita kuti maEV edu ekuchaja maPCB akwanise kubata anoenderera epamusoro-simba mitoro nekuvimbika kwakanyanya.

800V Architecture uye Chengetedzo Zvinodiwa

MaEV emazuva ano anoshandisa 800V mabhatiri anogonesa kukurumidza kuchaja netambo dzakatetepa. Iyi voltage level inoda kutarisisa kwakasarudzika kuchengetedzeka uye kuzviparadzanisa nevamwe muPCB dhizaini.

IPC-2221 inotsanangura nzvimbo shoma, asi isu tinowedzera 50% yekuchengetedza margin:

• Creepage kureba: 15mm inoshandiswa (10mm zvishoma)
• Kuchenesa kuburikidza nemhepo: 12mm inoshandiswa (8mm zvishoma)
• Yakasimbiswa yekuzviparadzanisa nevamwe: 8mm pa277VAC
• Zvenyama slots pakati voltage domains

Isolation slots inovimbisa kuchengetedzeka kunyangwe nekusvibiswa kana kutadza kwechikamu. Isu tinofambisa 3mm slots pakati pepuraimari nesekondari, kuchengetedza simba nematabo akaputsika panguva yegungano. Mushure mehuwandu, ma tabo anobviswa achisiya yakazara galvanic isolation.

Zvikamu zvekuchengetedza zvinoda kutarisirwa zvakanyanya. Y-capacitors inovhara kupatsanurwa kweEMI asi inofanira kunge iri mhando dzekuchengetedza. Optocouplers dzinoda nzvimbo dzekuchengetedza dze6mm kudzivirira nzira dzekupinda. Ruzivo rwedu rwePCB yepower module runovimbisa kushandiswa kwakazara kwekuchengetedza.

Wide-Bandgap Semiconductors muKuchaja Zvishandiso

Silicon carbide (SiC) uye gallium nitride (GaN) semiconductors inogonesa kushanda kusati kwamboitika muEV kuchaja, asi nanosecond yavo yekuchinja inomhanyisa inogadzira matambudziko matsva.

Pa50V/ns switching kumhanya, 2nH yeparasitic inductance inogadzira 100V overshoot-zvichigona kuparadza zvishandiso. Isu tinoderedza parasitics kuburikidza ne:

• Zvina-mutsetse zvishoma zvine simba riri pedyo / pasi ndege
• Vertical power loops through via arrays
• Kelvin source yekubatanidza yegedhi madhiraivha
• Kuiswa kwechikamu kunoderedza loop nzvimbo

Maseketi ekufambisa egedhi anoda kunyatsorongeka. Matinji ari pasi pe10mm kureba, kupindirana kweimpedance kuti nguva ikwane, uye simba regedhi rakaparadzana rinodzivirira pasi. Matekiniki aya akagadziriswa kuburikidza nekugadzira kwedu kweGaN power PCB anovimbisa kushanda kwakavimbika kwe-wide-bandgap.

Kukurukurirana Protocol Support

Machaja eEV emazuva ano haasi ekungounza magetsi chete — iwo masisitimu akangwara anotaurirana nemotokari, marineti ekubhadhara, uye magidhi anoshanda.

Maitiro eCHAdeMO neCCS anoda bhazi reCAN rinomhanya zvakanyanya rine impedance inodzorwa, kupatsanura zvipingamupinyi zvekuchengetedza, uye dziviriro yakasimba yeESD. Kutaurirana kunofanira kuramba kuchienderera mberi pasinei nekuchinja kwemagetsi kuri pedyo.

Kubatana kweOCPP backend kunoita kuti utarise uri kure kuburikidza neEthernet nemagetsi akabatanidzwa, mamodemu efoni anoda antenna isolation, uye zvinhu zvakachengeteka zvekugadzirisa kubhadhara. Ruzivo rwedu rwePCB rwekuchaja pasina waya runotungamira kubatanidzwa kwekutaurirana kwakavimbika.

Smart grid maficha anosanganisira kuyera kuyera, kubatanidzwazve, uye V2G kugona kunoda yakasanganiswa-signal dhizaini. Digital zvikamu zvinoda kuparadzaniswa kubva kumagetsi maseketi uku uchichengetedza yakavimbika data exchange.

Mibvunzo Inonyanya Kubvunzwa
