Voltage: Kiyi Yakavanzika Yekuvhura Ruzivo Rwakanaka rwekuchaja EV

Kana vatyairi vemagetsi vachitaura nezvekuchaja, "kumhanya" ndiko kunonyanya kukosha. Asi chinhu chinonyanya kukosha pakuchaja nekukurumidza chinopfuura kungotarisa simba chete. Voltage ndiyo inonyanya kutsanangura muganho wepamusoro wekuchaja, inokanganisa hutano hwebhatiri kwenguva refu, uye inotoumba nzira dzetekinoroji dzemangwana.
Chinyorwa chino chinotsanangura fizikisi iri shure kwemagetsi—uye chinoratidza kuti inochinja sei nguva yega yega yekuchaja yaunosangana nayo.

1. Kukwira Kwesimba - Nei 800V Yakava Nzvimbo Yekuvandudza Tekinoroji

Zvichienderana nefizikisi yekutanga, simba (P) = voltage (V) × current (A).
Kuti uwedzere simba rekuchaja, unogona kukwidza voltage kana kusunda current yakawanda. Asi current yakakwira inounza matambudziko makuru: tambo dzakakora, kupisa kwakawanda, uye kurasikirwa nesimba kwakawanda. Izvi zvinoita kuti kukwidziridzwa kwevoltage kuve nzira inoshanda yekuvandudza.

Ndosaka mapuratifomu e800V ane voltage yepamusoro achionekwa seanonyanya kukosha kune tekinoroji yeEV.
Ngatitorei Porsche Taycan—imwe yemotokari dzekutanga dze800V EV dzakagadzirwa nehukuru. Sisitimu yayo inotsigira simba rekuchaja rinosvika 320 kW. Chinonyanya kukosha ndechekuti, panguva imwe chete yekufambisa simba, magetsi anogona kuderedzwa nehafu, zvichideredza zvakanyanya kurasikirwa nekupisa uye kuvandudza kushanda zvakanaka kwekuchaja.

Mugumisiro wacho unooneka sewakanaka zvikuru: Taycan inogona kuchaja kubva pa10% kusvika ku80% mumari shoma se Maminetsi gumi nemaserepachaja ine simba re800V rinomhanya zvakanyanya.

2. Kuchinjana Kwekuenderana — Uchenjeri uye Mutengo we "Kuenderana Kusina Kusimba"

Dambudziko riripo nhasi nderekuti maEV ane simba re800V haagone kuwana machaja ane simba remagetsi akaenzana.
Muenzaniso wakanaka iHyundai IONIQ 5. Kunyange zvazvo mota iyi ichitsigira kuchaja kwe800V, zviteshi zvakawanda zveTesla Supercharger V3 zvinopa simba rinenge 500V.
Kuti mota ikwanise kuchinja, inofanira kuvhura DC/DC converter yayo yemukati uye "kudzikisa" voltage kusvika ku400V—zvichideredza simba rekuchaja rinosvika pakakwirira. 135 kW, pasi pekukwanisa kwayo kwepamusoro-soro kwe257 kW.

Kuwirirana uku kwakaderera inyanzvi yekugadzira zvinhu—asi kunouya nekurasikirwa kwekushanda.
Uye muganho uyu uri kukurumidzisa shanduko yeindasitiri kuenda kuzvivakwa zvekuchaja zveveruzhinji zvine simba guru.

3. Miganhu Yekuchengetedza — Miganhu Yakazara Yekuyera Voltage

Sezvo mwero wemagetsi uchikwira, kuchengetedzeka kunova mutsetse mutsvuku usingakurukuriranwe.
Voltage yakakwira inoisa zvinodiwa zvakanyanya pakuputira, kutarisira kupisa, uye kutarisa panguva chaiyo.

IEC 61851 inotsanangura miganhu yakajeka:

• Kusvika ku1000V AC
• Kusvika ku1500V DC

Panguva imwe chete, hurongwa hwekupedzisira hweCCTA hwekusimbisa ikozvino hunofukidza 150V–1000V, uye iri kuisa hwaro hwemasisitimu ekuchaja emhando ye megawatt mune ramangwana.

Mitemo iyi pamwe chete inoumba "zvidziviriro" zvichiita kuti kubhadharisa nekukurumidza kusambokanganisa kuchengetedzeka.

4.Remangwana — Kupfuura Voltage Yakakwira, Kuenda kuVoltage Yakangwara

Danho rinotevera remakwikwi harisi rekungowedzera ma voltage platforms kubva pa400V kusvika pa800V zvichienda mberi.
Kukosha kwechokwadi kuri mu manejimendi yemagetsi akangwara:

• Kudzora BMS kwakaringana
  Kugadziriswa kwemagetsi kunokwira panguva yekupedzisira yekuchaja kuti kuenzane nekumhanya uye kugara kwenguva refu kwebhatiri.
• Kubatana pakati pemotokari nechaja
  Kutaurirana panguva chaiyo pakati pechaja neBMS yemotokari kuti igadzire curve yekuchaja yakakodzera.
• Kuchinjika kwemamiriro ekunze ese
  Masisitimu ekupisa epamusoro anoita kuti kuchaja nekukurumidza kurambe kwakachengeteka uye kuchishanda zvakanaka kana kuchitonhora zvakanyanya kana kupisa.

Mhedziso

Voltage inopfuura parameter yehunyanzvi inotonhora. Inobatanidza kushanda zvakanaka kwekuchaja, kuenderana kwechaja, kuchengetedzeka kwesystem, uye hutano hwebhatiri.
Kune varidzi vemotokari dzemagetsi, kunzwisisa voltage yepamusoro yekuchaja mota yako kunokubatsira kuronga rwendo rurefu uye kusarudza machaja anovhura mashandiro ayo akazara.
Kune indasitiri, kushanduka kwemagetsi kunomiririra rudzi rwakakwana mune zvesainzi yezvinhu, mainjiniya emagetsi, uye kutonga kwakangwara.

Sezvo tekinoroji yekuchaja ichifambira mberi, machaja pachawo anofanira kutsigira ma voltage akafara, huwandu hwesimba hwakakwira, uye ma algorithms ekudzora akangwara.
Izvi ndizvo chaizvo Simba Itsva reInjetari kuvaka—machaja anoratidza meseji imwe chete iri nyore:
Pasinei nekuti tekinoroji yemagetsi inoshanduka sei, tinopa simba nekukurumidza, rakachengeteka, uye rakavimbika kune mota yega yega.
