Intshayelelo: I-Paradox ye-Mass kwiXesha loMbane

Utshintsho oluvela kwiinjini zokutsha zangaphakathi (ICE) ukuya kwizithuthi zombane (EVs) lumele utshintsho olubalulekileyo kubunjineli beemoto ukusukela oko kwamkelwe umgca wokuhlanganisa. Nangona kunjalo, olu tshintsho okwangoku lusekelwe kwinyani enzima: uxinano lwamandla eebhetri ze-lithium-ion. Nangona ipetroli inoxinano lwamandla olumalunga ne-12,000 Wh/kg, iipakethe zebhetri zangoku zinzima ukudlula i-250-300 Wh/kg kwinqanaba leseli, kwaye zincinci kakhulu kwinqanaba lepakethe ngenxa yesakhiwo, ukupholisa, kunye nokhuseleko oluphezulu.

Oku kungafani kufuna iibhetri ezinkulu ukuze kufikelelwe kumanqanaba afana nezithuthi ze-ICE, ezidla ngokuba nobunzima obuphakathi kwe-500kg kunye ne-900kg. Lo "mthwalo unzima" uqala isiphumo se-ripple kuyo yonke into ye-dynamics yesithuthi, ukusuka kwi-coefficient of friction efunekayo ukuze kuqhotyoshwe ukuya kwimida ye-elastic deformation ye-chassis. Eli nqaku liphonononga i-physics entsonkothileyo, imida yeekhemikhali, kunye nobunzima bobunjineli obufunekayo kubunzima bebhetri ye-EV.

I-equation esisiseko yamandla e-kinetic, $E_k = \frac{1}{2}mv^2$, igxininisa ukuba kutheni ubunzima butshaba lokusebenza kakuhle. I-EV enobunzima obuyi-2,500kg (ubunzima obuqhelekileyo kwii-SUV zombane eziphambili) inamandla e-kinetic angaphezu kwama-66% kune-ICE counterpart eyi-1,500kg ngesantya esifanayo.

Ukuze inciphise le ngxaki, inkqubo yokuqhobosha kufuneka iguqule la mandla abe bubushushu okanye, kwimeko yee-EV, ibe ngamandla ombane ngokusebenzisa ukuqhobosha okuvuselelayo. Ingqiqo ye-algorithmic yeenkqubo zokuqhobosha ezixutyiweyo kufuneka iphathe oku kulandelayo:

• Imida Yokuncamathela Kwindlela Yamatayara:Ukwehla okuphezulu kwesantya $a_{max}$ kunqunyelwe yi $\mu g$, apho i $\mu$ yi-coefficient of friction. Izithuthi ezinzima zonyusa amandla aqhelekileyo $N$, nto leyo enyusa amandla okungqubana $F_f = \mu N$, kodwa uvakalelo lwamatayara kumthwalo (uvakalelo lomthwalo) luthetha ukuba i-coefficient of friction iyancipha njengoko umthwalo othe nkqo unyuka.
• Ukusasazwa kobushushu:Iibhuleki zokungqubana zemveli kwiimoto ze-EV ezinzima kufuneka zibe nkulu kakhulu ukuthintela ukufiphala kweebhuleki ngexesha longxamiseko apho ukuvuselelwa kwazo kunganeliyo.

1.2 Ixesha eliphakathi le-Inertia kunye ne-Yaw Rate

Ukubekwa kwebhetri—ngokuqhelekileyo kwisimo se-“skateboard” phakathi kwee-axles—kuyitshintsha kakhulu i-polar moment of inertia yesithuthi. Ngokugxininisa ubunzima obuphantsi naphakathi kwamavili, ii-EV zihlala zibonisa iziko eliphantsi lomxhuzulane (CoG), nto leyo ephucula uzinzo lokuqengqeleka. Nangona kunjalo, ubunzima obuphezulu bunyusa i-moment of inertia $I = \sum m_i r_i^2$.

Umzuzu ophezulu wokungakhathali umelana notshintsho kwi-yaw (ukujika). Uyilo lwempendulo yokuqondisa lufuna ii-algorithms ezintsonkothileyo ze-torque-vectoring ukuze woyise imvakalelo "yobuvila" ye-chassis enzima. Oku kubandakanya:

5. I-Algorithmic Logic yoLawulo lweMisa

IiYunithi zoLawulo lweZithuthi eziPhambili (ii-VCU) zisebenzisa ii-algorithms zoqikelelo lobunzima bexesha langempela. Ngokujonga igalelo le-torque kunye nokukhawuleziswa okubangelwa yiyo ($a = F/m$), i-VCU inokuqikelela umthwalo wangoku (abakhweli + imithwalo) kwaye ilungise:

• Imida yoLawulo loZinzo lwe-Electronic (ESC).
• Uxinzelelo lokumiswa komoya.
• Amandla okuqhobosha okuvuselelayo.

(Qaphela: La ngamagama okuqala ali-1200. Siyaqhubeka kwicandelo elilandelayo…)

6. Ubunjineli boLwakhiwo obuPhambili: Uguquko lweSeli-ukuya kwiChassis (CTC)

Njengoko ii-OEM zeemoto zizama ukunciphisa isohlwayo esikhulu seebhetri, eli shishini litshintsha ukusuka kuyilo lweemodyuli ukuya kwizisombululo zesakhiwo ezidibeneyo. Kwimizobo yemveli ye-EV, iphakheji yebhetri yayineeseli ezigcinwe kwiimodyuli, ezathi emva koko zavalwa kwitreyi yebhetri eqinisiweyo. Le ndlela "yeRussian Doll" yadala ukuphindaphinda okukhulu kwizixhobo zendlu, nganye yongeza iigram ezathi ekugqibeleni zalingana neekhilogram.

6.1 Intsebenziswano yoomatshini ye-CTC

Indlela yokusebenzisa iCell-to-Chassis (CTC) isusa imodyuli kunye nesigqubuthelo sepakethi, idibanisa iiseli zebhetri ngqo kwisakhiwo somgangatho wesithuthi. Ngokwembono yobuchule bokwakha, oku kuguqula ibhetri ibe "yiphaneli yesandwich" enokuqina okuphezulu kakhulu.

Ukumodela kweMathematika koBulukhuni beCTC:Ukuqina kwe-flexural $D$ kwesakhiwo sesandwich kunikwa ngu: $D = E_f \frac{bt_f d^2}{2} + E_c \frac{bt_c^3}{12}$ Apho:

• I-$E_f$ yimodulus kaYoung yeeshiti zobuso (umgangatho we-chassis kunye nepleyiti esezantsi).
• I-$t_f$ bubukhulu beeshiti zobuso.
• I-$d$ ngumgama ophakathi embindini weeshiti zobuso.
• I-$E_c$ kunye ne-$t_c$ zibhekisa kwisiseko (iiseli zebhetri kunye ne-potting compound).

Ngokusebenzisa amandla aphezulu okuxinzelela eeseli ezisilinda okanye eziziiprismatic, iinjineli zinokufumana itshasi eqinileyo ngama-20-40% kunesakhelo se-ICE sendabuko ngelixa zinciphisa ubunzima obupheleleyo nge-10-15%. Nangona kunjalo, olu manyano luzisa imingeni ebalulekileyo ekusebenzeni nasekusetyenzisweni kwakhona, njengoko iiseli "zakhelwe ngaphakathi" kwisithuthi.

6.2 Imingeni yoLawulo loBushushu kwiibhetri zeZakhiwo

Iphakheji eqinileyo neyolwakhiwo ishiya indawo encinci yokupholisa imijelo. Kufuneka ukulinganisa okuphucukileyo kwe-CFD (iComputational Fluid Dynamics) ukuqinisekisa ukusasazwa kobushushu obufanayo. I-equation yokudlulisa ubushushu yephakheji: $\rho C_p \frac{\partial T}{\partial t} = \nabla \cdot (k \nabla T) + \dot{q}_{gen}$ Apho $\dot{q}_{gen}$ imele ukuveliswa kobushushu bangaphakathi ukusuka ekufudumaleni kweJoule kunye neempendulo ze-electrochemical. Kuyilo lwe-CTC, itshasi ngokwayo idla ngokusebenza njengesinki sobushushu sesibini, ifuna ukwahlulwa kobushushu obuphucukileyo ukukhusela ikhabhini yabakhweli ngelixa igcina ubushushu beseli ngaphakathi kwefestile efanelekileyo ye-20°C ukuya kwi-40°C.
