Kakaretso

Axle ea motlakase ea likoloi (eAxle) ke "unit ea mantlha ea motlakase" ea likoloi tsa motlakase (li-EV), ka tsoelo-pele ea eona ea theknoloji e susumetsang ka ho toba mefuta, ts'ebetso le bohlale. Pampiri ena e sekaseka ka mokhoa o hlophisehileng likarolo tsa mantlha (motor, inverter, reducer, jj.) le mekhoa ea nakong e tlang (kopanyo, bokhoni, ho ikamahanya le maemo a phahameng a motlakase, bohlale) ba li-eAxles, e senola karolo ea tsona ea bohlokoa ntlafatsong ea indasteri ea EV.

2. Likarolo tsa Bohlokoa tsa Li-Axle tsa Motlakase

eAxle ke sistimi e kopaneng ea "motor + inverter + reducer," e nang le likarolo tsa bohlokoa le mesebetsi e latelang:

2.1 Enjene: "Pelo" ea Tlhahiso ea Matla

Mechini e sa feleng e tsamaisanang le makenete (PMSM) e busa, e fihlella bongata ba matla a 5000W/kg (mohlala, Tesla Model 3) le bokgoni ba >97%. Mekhoa: Dirothara tse hatisitsweng ka 3D (tse fokotsang maqhubu a torque ho 0.3%) le makenete a hahiloeng ka sebopeho sa V (ho ntlafatsa phallo ya makenete ya sekgeo sa moya).

2.2 Inverter: "Boko" ba Phetoho ea Matla

Ho tloha ho di-IGBT tse thehilweng ho silicon ho ya ho disebediswa tse nang le lekhalo le leholo (SiC/GaN), tahlehelo ya ho tsamaisa motlakase e fokotswa ka 50%, mme maqhubu a ho chencha a eketsehile ka 10x (mohlala, inverter ya Porsche Taycan SiC), ka bokgoni ba sistimi bo fetang 96%.

2.3 Mofokotsi: "Hub" ea Torque Amplification

E fetoha ho tloha meralong ea lebelo le le leng ho ea ho ea lebelo le lengata (mabelo a mabeli/mabelo a mane), e tšehetsang "mokhoa o tlaase oa torque e phahameng + bokhoni ba lebelo le phahameng" (mohlala, Porsche Taycan Turbo S), e fokotsa lebelo la 0-100km/h ka metsotsoana e 0.5.

2.4 Dimojule tse Thusang: Kutlo e Bohlale le Tshebedisano mmoho

Di-sensor tse kopaneng tsa hajwale/mocheso/boemo (±0.5%/±1℃/±0.1° ho nepahala) di buisana le BMS (taolo ya betri) le ADS (ho kganna ka boikemelo) ka CAN/Ethernet, ho nolofalletsa tlhahiso ya torque e lokisitsweng esale pele (mohlala, tshebedisano mmoho ya Tesla FSD).

3. Mekhoa ea Nts'etsopele ea Li-Axle tsa Motlakase

3.1 Kopanyo: Ho Fokotsa Boholo le Litšenyehelo

Ka "di-casting e kopaneng + moralo oa modular" (mohlala, Huawei DriveONE, XPeng G6 eAxle), bophahamo ba modumo bo fokotseha ka 40% mme litšenyehelo li fokotseha ka 25%, e leng se susumetsang "kopanyo ea li-domain tse ngata."

3.2 Bokgoni: Taolo ea Lisebelisoa tse Sephara tsa Bandgap

SiC/GaN e tla nkela di-IGBT tse thehilweng ho silicon sebaka (karolo ya mmaraka ya 70%+ ka 2027), e fihlelle bokgoni ba sistimi ba 97% mme e atolose sebaka ka 10% (mohlala, NIO ET7 eAxle).

3.3 Ho Ikamahanya le Motlakase o Phahameng: Ho Ikamahanya le Sethala sa 800V

E tšehetsa ho tjhaja ha 250kW ka potlako e phahameng (ho eketsa sebaka sa 300km ka metsotso e 10) ka maqhubu a hona joale a

3.4 Bohlale: Tšebelisano e tebileng le ho khanna ka boikemelo

Li-NPU tse kopaneng li ntlafatsa kabo ea torque ka li-algorithms tsa AI (mohlala, taolo ea matla a boletsoeng esale pele), ka latency ea karabelo
