Kedu mgbanwe nke ikpo okwu 800V ga-eweta?

Ọ bụrụ na emelitere ihe owuwu ụgbọ ala eletrik na 800V, a ga-ebuli ụkpụrụ nke ngwaọrụ ya dị elu ya, a ga-edochikwa inverter site na ngwaọrụ IGBT ọdịnala gaa na ngwaọrụ SiC ihe MOSFET. Ọnụ ego nke inverter n'onwe ya bụ nke abụọ na mpaghara batrị. Ọ bụrụ na ị kwalite na SiC, ọnụ ahịa ahụ ga-arịgo n'ọkwa ọzọ.

Mana maka OEM, ngwa nke silicon carbide n'ozuzu ọ bụghị naanị na-atụle ọnụahịa nke ngwaọrụ ike, mana nke ka mkpa, mgbanwe ọnụahịa nke ụgbọ ala dum. Ya mere, ọ dị mkpa ịchọta nguzozi n'etiti ego nchekwa ego nke SiC wetara na ọnụ ahịa ya dị elu.
N'ihe gbasara SiC, onye mbụ nwara ya bụ Tesla.

Na 2018, Tesla dochie IGBT modul na silicon carbide modul maka oge mbụ na Model 3. N'otu ọkwa ike ahụ, ngwugwu ngwugwu nke silicon carbide modul dị ntakịrị karịa nke silicon modul, na mgbanwe mgbanwe na-ebelata site na 75%. Ọzọkwa, ọ bụrụ na agbanwere, iji SiC modul kama IGBT modul nwere ike ịbawanye arụmọrụ sistemụ site na ihe dịka 5%.

Site n'echiche ọnụ ahịa, ọnụ ahịa nnọchi rịrị ihe fọrọ nke nta ka ọ bụrụ yuan 1,500. Otú ọ dị, n'ihi nkwalite nke arụmọrụ ụgbọ ala, ike batrị arụnyere ebelatala, na-echekwa ego n'akụkụ batrị.
Enwere ike iwere nke a dị ka nnukwu ịgba chaa chaa maka Tesla. Nnukwu ọnụ ahịa ahịa ya na-akwụ ụgwọ. Tesla dabere na nnukwu nzọ a iji jide teknụzụ na ahịa nke sistemụ batrị 400V.
N'ihe banyere 800V, Porsche butere ụzọ n'ịkwado ụgbọ ala egwuregwu Taycan eletrik niile na sistemụ 800V na 2019, na-ewepụta asọmpi ogwe aka maka ihe owuwu voltaji dị elu nke 800V nke ụgbọ ala eletrik.
Enwere ihe "na-ekwesịghị ekwesị" gbasara nyocha ego site n'echiche Porsche. E kwuwerị, ọ na-elekwasị anya na mmetụta ụgbọ ala okomoko ma na-elekwasị anya na ọnụahịa nke ika.
Mana n'ihe gbasara mmepe teknụzụ na ngwa, nke a bụ nnukwu ọrụ na-emetụta ahụ dum. Dị ka ihe atụ, n'okpuru 800V elu-voltaji chaja, voltaji nke batrị batrị ga-adịtụ ka 800V, ma ọ ga-ọkụ n'ihi na nnukwu chaja ugbu a. Tụkwasị na nke ahụ, ọ bụghị nanị na-agụnye usoro nchaji, kamakwa usoro batrị, usoro eletriki eletrik, ngwa ngwa voltaji dị elu na usoro wiring, na-emetụta mmalite, ịkwọ ụgbọala, ikuku oyi na-eji ụgbọ ala, wdg.

Ọ bụrụ na ịchọrọ ịmatakwu gbasara nke a, biko nweere onwe gị ịkpọtụrụ anyị.
