China EV Chaja PCB Manufacturing le Kopano

Highleap Electronics e fana ka litharollo tse felletseng tsa tlhahiso le kopano ea PCB ho pholletsa le makala a makoloi, a indasteri, a likhokahano le matla. Li-PCB tsa ho tjhaja tsa EV li emela e 'ngoe ea litsebi tsa rona tse hlokang tekheniki, moo ts'ebetso e kholo ea motlakase e kopanang le maemo a ts'epahalo ea koloi. Ha likoloi tsa motlakase li ntse li fetola lipalangoang, re etsa liboto tsa litšebeletso tsa motlakase tse matlafatsang phetoho ena.

Li-PCB tse tjhajang tsa Koporo e boima ea Koporo bakeng sa Hona Joale e Phahameng

Li-PCB tse tjhajang tsa EV li tlameha ho mamella litlhoko tse fetelletseng tsa hajoale ho feta lisebelisoa tsa elektroniki tse tloaelehileng. Lichaja tse lebelo haholo tse fihlang ho 350kW li ka fana ka li-amps tse fetang 500, tseo mapolanka a koporo a tloaelehileng a 1–2oz a ke keng a li tšehetsa. Ho netefatsa ts'ebetso e bolokehileng le e tšepahalang, li-PCB tse tjhajang EV li sebelisa
theknoloji e boima ea koporo ea PCB ho fihlela ho 10-20oz, e nolofalletsang phepelo ea matla e tsitsitseng ntle le ho chesa haholo.

Ho Highleap Electronics, ts'ebetso ea rona ea tlhahiso ea li-PCB tsa ho tjhaja tsa EV - e hahiloeng holim'a boiphihlelo bo tsoetseng pele ba tlhahiso ea li-PCB - e netefatsa taolo e nepahetseng ea botenya ba koporo, kabo e ntlafalitsoeng ea hona joale, le li-vias tse matla tsa mocheso. Mekhoa ena e thibela libaka tse chesang haholo 'me e tiisa ho tšoarella nako e telele, e leng se etsang hore li-PCB tsa rona tsa ho tjhaja tsa EV e be motheo o tšepahalang bakeng sa litsamaiso tsa ho tjhaja tsa hona joale tse nang le hona joale e phahameng.

Tsamaiso ea Thermal ho EV Chaging PCBs

Ho tšepahala ha mocheso ke ntlha e hlalosang moralo oa PCB oa ho tjhaja EV. Leha e sebetsa hantle ka 95%, tjhaja e potlakileng ea 150kW DC e hlahisa li-kilowatt tse 'maloa tsa mocheso tse tlamehang ho qhaloa khafetsa. Ho fapana le lihlahisoa tsa bareki, li charger tsa EV li matha bosiu le motšehare libakeng tse ka ntle ho tloha -40°C ho ea +50°C.

Re tjhaja li-PCB tsa EV tse nang le litharollo tse tsoetseng pele tsa mocheso tse kenyelletsang li-vias tse tlatsitsoeng ka koporo, tse ntlafalitsoeng ka li-arrays, le likaroloana tsa mantlha tsa tšepe bakeng sa ho tsamaisa mocheso o phahameng. Bakeng sa lijaja tse matla a holimo ho 100kW, re kopanya likhokahano tse pholileng tsa metsi le ho beha leihlo mocheso ho netefatsa ts'ebetso e sa sitisoeng. Maano ana a meralo a etsa hore li-PCB tsa rona tse tjhajang EV li khone ho sebetsana le meroalo e matla e tsoelang pele ka ts'epahalo e kholo.

800V Litlhoko tsa Mehaho le Tšireletso

Li-EV tsa sejoale-joale li sebelisa libeteri tsa 800V tse nolofalletsang ho tjhaja kapele ka likhoele tse tšesaane. Boemo bona ba motlakase bo hloka tlhokomelo e ikhethang mabapi le polokeho le ho itšehla thajana ho moralo oa PCB.

IPC-2221 e bolela bonyane ba sebaka, empa re eketsa 50% moeli oa polokeho:

• Sebaka sa Creepage: 15mm e kentsoe (10mm bonyane)
• Ho hlaka ka moea: 12mm e kentsoe (8mm bonyane)
• Ho itšehla thajana ho matlafalitsoeng: 8mm ho 277VAC
• Li-slots tsa 'mele lipakeng tsa libaka tsa motlakase

Li-slots tsa ho itšehla thajana li netefatsa polokeho le ha ho na le tšilafalo kapa karolo e hlolehileng. Re tsamaisa li-slots tsa 3mm lipakeng tsa mantlha le tsa bobeli, re boloka matla ka li-tab tse arohaneng nakong ea kopano. Ka mor'a palo ea batho, li-tab lia tlosoa ho siea ho itšehla thajana ho feletseng.

Likarolo tsa polokeho li hloka tlhokomelo e khethehileng. Li-capacitor tsa Y li kopanya karohano bakeng sa ho thibela EMI empa e lokela ho ba mefuta e lekantsoeng ka polokeho. Li-optocouplers li hloka libaka tsa ho boloka tsa 6mm tse thibelang litsela tsa ho kheloha. Phihlelo ea rona ea PCB ea module ea motlakase e netefatsa ts'ebetso e felletseng ea polokeho.

Wide-Bandgap Semiconductors ho Likopo tsa ho tjhaja

Silicon carbide (SiC) le gallium nitride (GaN) semiconductors li thusa ho sebetsa ka mokhoa o sa lebelloang oa ho tjhaja ha EV, empa lebelo la bona la nanosecond switching le baka mathata a macha.

Ka lebelo la ho fetoha la 50V / ns, 2nH ea inductance ea parasitic e etsa hore 100V e fetele - e ka senyang lisebelisoa. Re fokotsa li-parasitics ka:

• Bonyane ba mekhahlelo e mene e nang le lifofane tse haufi tsa matla / fatše
• Matla a emeng a kena ka har'a lihlopha
• Kelvin mohloli oa likhokahano bakeng sa li-gate drives
• Ho beha likarolo ho fokotsa sebaka sa loop

Dipotoloho tsa heke di hloka ho nepahala ho ikgethang. Mehlala e ka tlase ho bolelele ba 10mm, impedance e tsamaellanang bakeng sa ho nepahala ha nako, le di-loop tse arohaneng tsa heke tse thibelang matla a fatshe. Mekhoa ena e ntlafaditsweng ka tlhahiso ya rona ya matla a GaN PCB e netefatsa ts'ebetso e tshepahalang ya sekgeo se seholo.

Tšehetso ea Protocol ea Puisano

Lichaja tsa sejoale-joale tsa EV ha se phepelo ea motlakase feela — ke litsamaiso tse bohlale tse hokahanang le makoloi, marang-rang a litefo, le li-grid operators.

Mekhoa ea CHAdeMO le CCS e hloka bese ea CAN e lebelo le phahameng e nang le impedance e laoloang, lithibelo tsa tšireletso tse arohaneng, le tšireletso e matla ea ESD. Puisano e tlameha ho tsoela pele ho sa tsotelehe li-kilowatts tsa motlakase tse haufi.

Khokahano ea OCPP backend e nolofalletsa ho beha leihlo hole ka Ethernet ka makenete a kopantsoeng, li-modem tsa selefounu tse hlokang ho itšehla thajana ha antenna, le likarolo tse sireletsehileng bakeng sa ts'ebetso ea litefo. Phihlelo ea rona ea PCB ea ho tjhaja ntle le mohala e tataisa kopanyo e tšepahalang ea puisano.

Likarolo tsa grid e bohlale ho kenyelletsa ho leka-lekanya mojaro, kopanyo e nchafalitsoeng, le bokhoni ba V2G li hloka moralo o rarahaneng oa lipontšo tse tsoakiloeng. Likarolo tsa dijithale li hloka ho itšehla thajana ho li-circuits tsa motlakase ha li ntse li boloka phapanyetsano ea data e tšepahalang.

Lipotso Asked hangata

Q: Ke liqholotso life tse ka sehloohong ho moralo oa PCB oa ho tjhaja oa EV?
A: Mathata a mantlha a kenyelletsa ho laola maqhubu a 500+ amp, ho tlosa li-kilowatt tsa mocheso, ho boloka ho itšehla thajana ho 800-1000V, le ho kopanya mekhoa ea puisano. Highleap Electronics e sebetsana le tsena ka ho sebetsa ka koporo e boima ho fihla ho 20oz, litharollo tse tsoetseng pele tsa mocheso, sebaka se tiileng sa polokeho, le boiphihlelo bo fapaneng ba lipontšo.

P: Ke litifikeiti life tse hlokahalang bakeng sa liteishene tsa ho tjhaja tsa EV?
A: Litifikeiti tsa bohlokoa li kenyelletsa UL 2202/IEC 61851 bakeng sa polokeho, FCC/CE bakeng sa mesi, le litlhoko tsa tikoloho. Meralo ea Highleap Electronics e netefatsa ho lateloa ka ho itšehla thajana, taolo ea EMI, le litokomane tse felletseng tse tšehetsang setifikeiti.

P: Na li-charger tsa EV li ka sebetsa ka matla a ka nchafatsoang?
A: E, lijaja tsa sejoale-joale li hokahana le matla a letsatsi, moea le polokelo ea betri. Highleap Electronics e etsa li-PCB tse tšehetsang phallo ea matla a mabeli, ts'ebetso ea grid-tie, le lits'ebetso tsa taolo ea matla ka rona. AI data center power PCB botsebi ba ho sebelisana le grid.

P: Nako e tloaelehileng ea ntlafatso ea li-PCB tsa tjhaja ea EV ke efe?
A: Ho Highleap Electronics: prototypes ka matsatsi a 5-7, hangata 2-3 moralo o pheta-phetoang, 'me o loketse tlhahiso ka libeke tse 6-8. Prototyping ea rona e potlakileng e sebelisa PCB ea ho tjhaja ka potlako haholo mekhoa e potlakisa nako-to-mmaraka haholo.
