Loluphi utshintsho oluya kuziswa liqonga le800V?

Ukuba i-architecture yemoto yombane iphuculwe kwi-800V, imigangatho yezixhobo zayo eziphezulu ze-voltage iya kuphakanyiswa ngokufanelekileyo, kwaye i-inverter iya kutshintshwa kwakhona ukusuka kwizixhobo ze-IGBT zendabuko ukuya kwizixhobo ze-SiC ze-MOSFET. Iindleko ze-inverter ngokwazo zesibini kuphela kumacandelo ebhetri. Ukuba uphucula kwi-SiC, iindleko ziya kunyuka ziye kwelinye inqanaba.

Kodwa kwii-OEMs, ukusetyenziswa kwe-silicon carbide ngokubanzi akuqwalaseli kuphela iindleko zezixhobo zamandla, kodwa kubaluleke kakhulu, utshintsho lweendleko zemoto yonke. Ngoko ke, kubalulekile ukufumana ibhalansi phakathi kokugcinwa kweendleko eziziswa yi-SiC kunye neendleko zayo eziphezulu.
Ngokubhekiselele kwiSiC, umntu wokuqala owayizamayo yayinguTesla.

Kwi-2018, i-Tesla ithathe indawo yeemodyuli ze-IGBT kunye neemodyuli ze-silicon carbide ngokokuqala ngqa kwiModeli 3. Kwinqanaba elifanayo lamandla, ubungakanani bephakheji yeemodyuli ze-silicon carbide zincinci kakhulu kuneemodyuli ze-silicon, kwaye ilahleko yokutshintsha iyancipha nge-75%. Ngaphezu koko, ukuba iguqulwe, ukusebenzisa iimodyuli zeSiC endaweni yeemodyuli ze-IGBT kunokunyusa ukusebenza kwenkqubo malunga ne-5%.

Ngokwembono yeendleko, ixabiso lokubuyisela linyuke phantse nge-yuan eyi-1,500. Nangona kunjalo, ngenxa yokuphuculwa kokusebenza kwesithuthi, umthamo webhetri ofakiweyo uncitshisiwe, ukonga iindleko kwicala lebhetri.
Oku kunokubonwa njengomdlalo omkhulu weTesla. Umthamo wayo omkhulu wemarike unciphisa iindleko. UTesla naye wayethembele kolu bhejo olukhulu ukubamba itekhnoloji kunye nentengiso yeenkqubo zebhetri ze400V.
Ngokumalunga ne-800V, i-Porsche ikhokele ekuxhobiseni imoto yezemidlalo ye-Taycan yombane yonke nge-800V inkqubo ngo-2019, ibeka ugqatso lweengalo kwi-800V ye-high-voltage architecture yezithuthi zombane.
Kukho into "engafanelekanga" malunga nokuhlalutya iindleko ngokwembono yePorsche. Emva kwayo yonke loo nto, igxile kwisiphumo semoto yodidi kwaye igxile kwiprimiyamu yophawu.
Kodwa malunga nophuhliso lweteknoloji kunye nokusetyenziswa, le yiprojekthi enkulu echaphazela umzimba wonke. Ngokomzekelo, phantsi kwe-800V yokutshaja okuphezulu kwe-voltage, i-voltage ye-pack yebhetri kufuneka inyuke ngokulinganayo ukuya kwi-800V, ngaphandle koko iya kutshiswa ngenxa yombane omkhulu wokutshaja. Ukongezelela, akubandakanyi kuphela inkqubo yokutshaja, kodwa kunye nenkqubo yebhetri, inkqubo yokuqhuba umbane, i-high-voltage accessories kunye ne-wiring harness system, echaphazela ukuqala, ukuqhuba, ukusetyenziswa kwe-air conditioning yesithuthi, njl.

Ukuba ufuna ukwazi ngakumbi malunga noku, nceda uzive ukhululekile ukuqhagamshelana nathi.
