I-Voltage: Isitshixo Esifihlakeleyo Sokuvula Amava Okutshaja E-EV Angcono

Xa abaqhubi be-EV bethetha ngokutshaja, "isantya" sisoloko sisihloko. Kodwa ipharamitha yokwenyani yobuchwephesha emva kokutshaja ngokukhawuleza ingaphezulu kakhulu kunomlinganiselo wamandla nje. I-Voltage yiyo ekugqibeleni echaza umda ophezulu wokusebenza kakuhle kokutshaja, ichaphazela impilo yebhetri yexesha elide, kwaye ikwabumba neendlela zobuchwepheshe zexesha elizayo.
Eli nqaku lichaza ifiziksi engasemva kwe-voltage—kwaye libonisa indlela eyichaphazela ngayo yonke iseshoni yokutshaja oyifumanayo.

1. Ukutsiba Kokusebenza Kakuhle — Kutheni i-800V Yaba Yindawo Yokugcina Ubuchwepheshe

Ngokwefiziksi esisiseko, amandla (P) = i-voltage (V) × yangoku (A).
Ukuze wonyuse amandla okutshaja, unganyusa i-voltage okanye utyhale i-current engaphezulu. Kodwa i-current ephezulu izisa iingxaki ezinkulu: iintambo ezijiyileyo, ubushushu obuninzi, kunye nokulahlekelwa ngamandla aphezulu. Oku kwenza ukuphakama kwe-voltage kube yindlela yokuphucula esebenza ngakumbi.

Yingakho amaqonga e-800V aphezulu e-voltage ethathwa njengexesha elibalulekileyo kwitekhnoloji ye-EV.
Cinga ngePorsche Taycan—enye yee-800V EV zokuqala eziveliswe ngobuninzi. Inkqubo yayo ixhasa amandla okutshaja ukuya kuthi ga kwi-320 kW. Okubaluleke ngakumbi, ngexesha elifanayo lokudluliselwa kwamandla, umbane ungancitshiswa ngesiqingatha, nto leyo enciphisa kakhulu ilahleko yobushushu kwaye iphucule ukusebenza kakuhle kokutshaja.

Isiphumo sisiphumo sokuba amava omsebenzisi abonakale engcono ngakumbi: iTaycan inokutshaja ukusuka kwi-10% ukuya kwi-80% ngemali encinci njenge imizuzu eli-18kwitshaja ekhawulezayo kakhulu ye-800V.

2. Ukuhambelana — Ubulumko kunye nexabiso “lokuhambelana okuphantsi”

Umceli mngeni namhlanje kukuba ii-EV ezine-800V azikwazi ukufumana rhoqo iitshaja ze-high voltage ezifanayo.
Umzekelo omhle yiHyundai IONIQ 5. Nangona imoto ixhasa ukutshaja kwe-800V, uninzi lwezikhululo zeTesla Supercharger V3 zibonelela malunga ne-500V.
Ukuze ikwazi ukuziqhelanisa, isithuthi kufuneka sivule i-DC/DC converter yaso yangaphakathi size “sehlise” i-voltage iye kwi-400V—sinciphise amandla okutshaja aphezulu ukuya malunga 135 kW, ingaphantsi kakhulu kumandla ayo aphezulu angama-257 kW.

Olu lungelelwaniso olusezantsi luyinjineli ekrelekrele—kodwa luza nokulahleka kokusebenza.
Kwaye lo mda ukhawulezisa utshintsho lweli shishini oluya kwiziseko zophuhliso zokutshaja zikawonke-wonke ezine-voltage ephezulu.

3. Imida yoKhuseleko — Imida epheleleyo yoKukhula kweVolthi

Njengoko amanqanaba ombane enyuka, ukhuseleko luba ngumgca obomvu ongenakuphikiswana ngawo.
Umbane ophezulu ubeka iimfuno ezingqongqo zokuthintela ubushushu, ulawulo lobushushu, kunye nokubeka esweni ngexesha langempela.

I-IEC 61851 ichaza imida ecacileyo:

• Ukuya kuthi ga kwi-1000V AC
• Ukuya kuthi ga kwi-1500V DC

Ngaxeshanye, isakhelo samva nje sokuqinisekiswa kweCCTA ngoku sigubungela 150V–1000V, kwaye ibeka isiseko seenkqubo zokutshaja zeklasi yee-megawatt ezizayo.

Le migangatho idibeneyo yenza "iintsika zokukhusela" eziqinisekisa ukuba ukutshaja ngokukhawuleza akuze kubeke ukhuseleko esichengeni.

4.Ikamva — Ngaphaya kweVoltage ephezulu, ukuya kwiVoltage ekrelekrele ngakumbi

Inqanaba elilandelayo lokhuphiswano alikho nje malunga nokunyusa amaqonga ombane ukusuka kwi-400V ukuya kwi-800V nangaphezulu.
Ixabiso lokwenyani lilele ulawulo lwe-voltage olukrelekrele:

• Ulawulo lwe-BMS oluchanekileyo
  Amanqanaba okuma kwe-voltage alungiswa kakuhle ngexesha lesigaba sokugqibela sokutshaja ukuze kulinganiswe isantya kunye nobude bebhetri.
• Ulungelelwaniso lwetshaja nesithuthi
  Unxibelelwano lwexesha langempela phakathi kwetshaja kunye ne-BMS yesithuthi ukuze kulungiswe igophe lokutshaja elifanelekileyo.
• Ukuguquguquka kwemozulu yonke
  Iinkqubo zobushushu eziphucukileyo ziqinisekisa ukuba ukutshaja ngokukhawuleza kuhlala kukhuselekile kwaye kusebenza kakuhle xa kubanda kakhulu okanye kushushu kakhulu.

Isiphelo

I-voltage ingaphezulu kakhulu kunepharamitha yobugcisa ebandayo. Idibanisa ukusebenza kakuhle kokutshaja, ukuhambelana kwetshaja, ukhuseleko lwenkqubo, kunye nempilo yebhetri.
Kubanini be-EV, ukuqonda i-voltage ephezulu yokutshaja kwesithuthi sakho kukunceda ucwangcise uhambo olude kwaye ukhethe iitshaja ezivula ukusebenza kwayo ngokupheleleyo.
Kwishishini, uphuhliso lwe-voltage lubonisa uhlanga olubanzi kwisayensi yezinto, ubunjineli bombane, kunye nolawulo olukrelekrele.

Njengoko iteknoloji yokutshaja itshintsha, iitshaja ngokwazo kufuneka zixhase uluhlu olubanzi lwevolthi, uxinano lwamandla oluphezulu, kunye nee-algorithms zolawulo ezikrelekrele.
Yiyo kanye le nto Amandla amatsha e-Injetiyakha—iitshaja ezibonisa umyalezo omnye olula:
Nokuba iteknoloji ye-EV itshintsha njani na, sinikezela ngamandla akhawulezayo, akhuselekileyo, nanokuthenjwa kwisithuthi ngasinye.
