Vagadziri vese uye varidzi vemotokari vanorota nezve mhedzisiro ye "kuchaja kwemaminetsi mashanu uye kutyaira 200km".
Kuti uite izvi mhedzisiro, zviviri zvikuru zvinodikanwa uye mapoinzi emarwadzo anofanirwa kugadziriswa:
Imwe, ndeye kuvandudza zvakanyanya mashandiro ekuchaja uye nekukurumidza kuwedzera bhatiri yekuchaja kumhanya.
Chechipiri, ndeye kuvandudza kushanda zvakanaka kwemotokari yese uye kuwedzera huwandu hwekutyaira pasi pesimba rakafanana.
Pano, tinogona kushandisa junior chikoro chepamusoro fizikisi kuti tinzwisise muchidimbu: P = UI. Saka kana iwe uchida kuwedzera simba, pane nzira mbiri chete dzekuwedzera ikozvino kana kuwedzera voltage.
Nekudaro, mafungu mahombe anokonzeresa kurasikirwa kwekupisa kukuru mukuchaja pfuti, tambo uye zvakakosha zvikamu zvemabhatiri emagetsi, uye muganho wepamusoro wekuvandudza dzidziso hauna kukura. Nokudaro, nzira yekuwedzera ikozvino "haisvikiki", kwete, inofanira kunge "kwete kure".
Saka, zvakadini nekuwedzera voltage?
Kana iyo system yazvino ikaramba yakamira, simba rekuchaja rinowedzera kaviri semagetsi system, ndiko kuti, iyo peak yekuchaja kumhanya inopetwa kaviri, uye nguva yekuchaja ichapfupikiswa zvakanyanya. Mukuwedzera, pasi pesimba rimwechete rekuchaja, kana magetsi ari akakwirira, ikozvino inogona kuderedzwa, uye waya haifaniri kunge yakakora, uye kushorwa kwekushisa kwesimba rekushandisa kwewaya kunoderedzwawo.
Naizvozvo, kana iwe uchiri kushandisa yekutanga 400V yekuchaja tambo saizi, unogona kuwedzera simba rekuchaja. Izvi zvinoreva kuti pasi pepuratifomu ye800V, tambo dzakatetepa dzekuchaja dzinogona kushandiswa.
Tsvagiridzo yeHuawei inoratidza kuti kuchaja nekukurumidza uchishandisa 800V yakakwira-voltage modhi inotsigira yakanyanya kuchaja ye30% -80% SOC, nepo yakaderera-voltage yakakwira-yazvino modhi inogona kungoita yakakwira simba rekuchaja pa10% -20% SOC, uye simba rekuchaja. inodonha zvakanyanya mune mamwe mitsara. fast. Zvinogona kuoneka kuti 800V yakakwira-voltage modhi inogona kutsigira kureba nekukurumidza kuchaja.
Iyo yakakwirira yekushanda kwekushanda kwemotokari yose, izvo zvinoreva kuti pasi pemamiriro ekugara nguva dzose, kukwirira kwebhatiri voltage, simba guru remotokari, uye kuwedzera kushanda kwemotokari.
Naizvozvo, iyo 800V yakakwira-voltage papuratifomu inogona nyore kuwana yakakwirira simba uye torque, pamwe nekuita zvirinani kukurumidza kuita. Kunyangwe kuvandudzwa kwesimba rekuzadzazve simba kwakaunzwa ne800V kumotokari dzemagetsi kuri hunhu, chimwe chezvipingamupinyi zvikuru mukuitwa kwe800V inyaya yemutengo.
Kana uchida kuziva zvakawanda pamusoro peizvi, tapota inzwa wakasununguka kutibata nesu.
