Zeziphi iinguqu eziza kuziswa liqonga le-800V?

Ukuba uyilo lwesithuthi sombane luphuculwe ukuya kwi-800V, imigangatho yezixhobo zaso eziphezulu zombane iya kuphakanyiswa ngokufanelekileyo, kwaye i-inverter nayo iya kuthatyathelwa indawo ukusuka kwizixhobo zemveli ze-IGBT ukuya kwizixhobo ze-SiC zeMOSFET. Ixabiso le-inverter ngokwayo lilandela kuphela izixhobo zebhetri. Ukuba uphucula ukuya kwi-SiC, ixabiso liya kunyuka liye kwelinye inqanaba.

Kodwa kwii-OEMs, ukusetyenziswa kwe-silicon carbide ngokubanzi akujongi nje kuphela iindleko zezixhobo zamandla, kodwa okubaluleke ngakumbi, utshintsho lweendleko zesithuthi siphela. Ke ngoko, kubalulekile ukufumana ibhalansi phakathi kokonga iindleko eziziswe yi-SiC kunye neendleko zayo eziphezulu.
Ngokuphathelele iSiC, umntu wokuqala ukuyizama yayinguTesla.

Ngowama-2018, iTesla yatshintsha iimodyuli ze-IGBT ngeemodyuli ze-silicon carbide okokuqala kwiModeli 3. Kwinqanaba elifanayo lamandla, ubungakanani bephakheji yeemodyuli ze-silicon carbide buncinci kakhulu kunobo beemodyuli ze-silicon, kwaye ilahleko zokutshintsha ziyancitshiswa ngama-75%. Ngaphezu koko, ukuba ziyaguqulwa, ukusebenzisa iimodyuli ze-SiC endaweni yeemodyuli ze-IGBT kunokunyusa ukusebenza kakuhle kwenkqubo malunga ne-5%.

Ngokwembono yeendleko, iindleko zokutshintsha zinyuke phantse nge-1,500 yuan. Nangona kunjalo, ngenxa yokuphuculwa kokusebenza kakuhle kwesithuthi, amandla ebhetri efakiweyo anciphile, nto leyo egcina iindleko kwicala lebhetri.
Oku kungathathwa njengomdlalo omkhulu kwiTesla. Ubungakanani bayo obukhulu bemarike buyayilungisa iindleko. ITesla ikwathembele kolu bhejo lukhulu ukuze ithathe itekhnoloji kunye nemarike yeenkqubo zebhetri ze-400V.
Ngokuphathelele i-800V, iPorsche yakhokela ekuxhobiseni imoto yezemidlalo iTaycan esebenzisa umbane kuphela ngenkqubo ye-800V ngo-2019, yaqala umdyarho weengalo kwisakhiwo se-800V esine-voltage ephezulu yezithuthi zombane.
Kukho into "engafanelekanga" malunga nokuhlalutya iindleko ngokwembono yePorsche. Kaloku, igxile kwimpembelelo yemoto yobunewunewu kwaye igxile kwixabiso lophawu.
Kodwa ngokubhekiselele kuphuhliso lwetekhnoloji kunye nokusetyenziswa kwayo, le yiprojekthi enkulu echaphazela umzimba wonke. Umzekelo, phantsi kokutshaja kwe-800V ephezulu, i-voltage yebhetri kufuneka inyuswe iye kwi-800V, kungenjalo iya kutsha ngenxa yamandla amakhulu okutshaja. Ukongeza, ayibandakanyi nje kuphela inkqubo yokutshaja, kodwa nenkqubo yebhetri, inkqubo yokuqhuba ngombane, izixhobo ze-high-voltage kunye nenkqubo ye-wiring harness, echaphazela ukuqala, ukuqhuba, ukusetyenziswa kwe-air conditioner yesithuthi, njl.

Ukuba ufuna ukwazi okungakumbi ngale nto, nceda ukhululeke ukuqhagamshelana nathi.
