40kW SiC inoshanda zvakanyanya DC EV yekuchaja Module

SiC high efficiency charging module inogona kushandiswa zvakanyanya sezvo kudiwa kwe high voltage fast charging kuri kuwedzera Mushure mekunge Porsche yatanga kuburitsa mota dzemhando yepamusoro dze800V Taycan munaGunyana 2019, makambani makuru emagetsi akaburitsa mota dzemhando yepamusoro dze800V dzinochaja nekukurumidza, dzakadai seHyundai IONIQ, Lotus Eletre, BYD Dolphin, Audi RS e-tron GT, nezvimwewo. Dzese dziri kutengeswa kana kuti dziri kugadzirwa zvakanyanya mumakore maviri aya. Kuchaja nekukurumidza kwe800V kuri kuva chinhu chikuru pamusika; CITIC Securities inofanotaura kuti panosvika gore ra2025, huwandu hwemamodheru ekuchaja ane simba guru huchasvika mamiriyoni 5.18, uye huwandu hwevanochaja huchawedzera kubva pari zvino hunopfuura zvishoma 10% kusvika 34%. Izvi zvichave simba guru rekusimudzira kukura kwemusika wekuchaja une simba guru, uye makambani ari kumusoro anotarisirwa kubatsirwa nazvo zvakananga. Sekureva kweruzivo rweveruzhinji, module yekuchaja ndiyo chikamu chikuru chemurwi wekuchaja, ichitora inenge 50% yemari yese yemurwi wekuchaja; pakati pavo, mudziyo wesimba re semiconductor unotora 30% yemari yekuchaja module, kureva kuti, module yesimba re semiconductor inotora inenge 15% yemari yekuchaja murwi, uye ndiyo ichava cheni huru yekubatsira mukugadzirwa kwemusika wekuchaja murwi. Parizvino, zvishandiso zvemagetsi zvinoshandiswa mukuisa mapombi ekuchaja zvinonyanya kuve maIGBT nemaMOSFET, ese ari zvigadzirwa zveSi-based, uye kuvandudzwa kwemapombi ekuchaja kusvika kuDC fast charging kwakaisa zvinodiwa zvakanyanya zvezvishandiso zvemagetsi. Kuti kuchaja mota kukurumidze sekunge kuwedzera mafuta pachiteshi chepeturu, vagadziri vemotokari vari kutsvaga zvinhu zvinogona kuvandudza kushanda zvakanaka, uye silicon carbide parizvino ndiyo inotungamira. Silicon carbide ine zvakanakira zvekudzivirira kupisa kwakanyanya, kuramba kumanikidzwa kwakanyanya, simba rakawanda, nezvimwewo, izvo zvinogona kuvandudza kushanda zvakanaka kwesimba uye kuderedza huwandu hwechigadzirwa. Mota zhinji dzemagetsi dzinoshandisa nzira dzekuchaja dzeAC dziri mundege, izvo zvinotora maawa akati wandei kuti dzichajike zvizere. Kushandisa simba rakawanda (rakadai se30kW zvichikwira) kuti mota dzemagetsi dzichajike nekukurumidza kwave nzira inotevera yakakosha yekuchaja. Pasinei nezvakanakira mapombi ekuchaja ane simba guru, zvinounzawo matambudziko akawanda, akadai se: kudiwa kwekushanda kwekuchinja mapombi ane simba guru, uye kupisa kunokonzerwa nekurasikirwa kwekuchinja. Zvisinei, zvigadzirwa zveSiC MOSFET ne diode zvine hunhu hwekudzivirira voltage yakakwira, kudzivirira kupisa kwakakwira, uye kukurumidza kuchinja frequency, izvo zvinogona kushandiswa zvakanaka mukushandisa mapombi ekuchaja. Zvichienzaniswa nemidziyo yechinyakare yakavakirwa pasilicon, mapombi esilicon carbide anogona kuwedzera simba rekubuda kwemapombi ekuchaja neinenge 30%, uye kuderedza kurasikirwa neanosvika 50%. Panguva imwe chete, zvishandiso zvesilicon carbide zvinogonawo kuwedzera kugadzikana kwemapombi ekuchaja. Pakuchaja mapombi, mutengo uchiri chimwe chezvinhu zvakakosha zvinodzivisa kukura, saka kuwanda kwesimba remapombi ekuchaja kwakakosha zvikuru, uye zvishandiso zveSiC ndizvo zvakakosha kuti uwane kuwanda kwesimba. Semudziyo une voltage yakawanda, kumhanya kwakanyanya, uye simba rakawanda, zvishandiso zvesilicon carbide zvinorerutsa chimiro chedunhu reDC pile charging module, zvinowedzera simba reyuniti, uye zvinowedzera simba rakawanda, izvo zvinopa nzira yekuderedza mutengo wesystem wepombi yekuchaja. Kubva pamaonero ekushandisa kwenguva refu uye kushanda zvakanaka, mapombi ekuchaja ane simba guru achishandisa michina yeSiC achaunza mikana mikuru pamusika. Sekureva kwedata reCITIC Securities, pari zvino, huwandu hwezvinhu zvinoshandiswa mumotokari itsva zvinoshandisa silicon carbide hunosvika 10% chete, izvo zvinosiyawo nzvimbo yakakura yenzvimbo dzinoshandiswa mumotokari dzine simba guru. Semutengesi anotungamira muindasitiri yekuchaja yeDC, MIDA Power yakagadzira uye yakaburitsa chigadzirwa chemodule yekuchaja ine simba rakawanda, module yekutanga yekudzivirira yeIP65 ine tekinoroji yemhepo yakazvimirira. Nechikwata chakasimba cheR&D uye musimboti wakatarisana nemusika, MIDA Power yakashanda nesimba rakawanda uye yakabudirira kugadzira module yekuchaja ye40kW SiC ine efficiency efficiency. Nekushanda kwakanaka kwepamusoro kunopfuura 97% uye super wide input voltage inotangira pa150VDC kusvika ku1000VDC, module yekuchaja ye40kW SiC inosangana nezvinodiwa zvese zvekupinda pasi rose uku ichichengetedza simba zvakanyanya. Nekukura nekukurumidza kwehuwandu hwemapombi ekuchaja, zvinotendwa kuti SiC MOSFETs, uye MIDA Power 40kW SiC yekuchaja module zvichashandiswa kakawanda mupombi yekuchaja inoda simba rakawanda mune ramangwana.
