Tsheb them chaw nres tsheb manufacturers hais txog: 800V High Voltage Charging System

Lub tsheb them chaw nres tsheb chaw tsim khoom: Lub 800V high-voltage system + super ceev them rau lub tsheb hluav taws xob tuaj yeem ua tiav lub sijhawm them ntawm 10 feeb thiab ntau yam ntawm 300 km, uas tuaj yeem daws qhov kev ntxhov siab ntawm kev rov ntxiv, thiab xav tias yuav dhau los ua txoj hauv kev loj. ntawm kev them nyiaj ceev. Cov tuam txhab tsheb loj hauv tsev thiab txawv teb chaws twb tau tsim cov qauv tsim nyog, thiab ntau lub 800V qauv yuav tsim ntau xyoo 2022. Tab sis nruab nrog 800V high-voltage platform tsheb them nyiaj hauv qhov kev them nqi hluav taws xob zoo tib yam, them ceev tsis yog raws li qhov kev cia siab, tuaj yeem. tsis ua tiav super ceev them, yog li cov pawg kawg ntawm cov khoom lag luam yuav tsum tau hloov kho dua tshiab hauv tandem nrog lub tsheb kawg, ib qho ntawm cov ntu ntawm txoj kev yuav tau txais txiaj ntsig.

Ua ntej, dab tsi yog high voltage them

Tsheb them chaw nres tsheb tuam txhab: Fast charging yog ceev them, chav ntsuas yuav raug them lub sij hawm (C). Qhov loj dua qhov kev them nyiaj ntau dua, lub sijhawm them luv luv.

Charging multiplier (C) = them tam sim no (mA) / roj teeb muaj peev xwm (mAh)

Piv txwv li, yog hais tias lub peev xwm ntawm lub roj teeb yog 4000mAh thiab lub charger tam sim no mus txog 8000mAh, lub charging multiplier yog 8000/4000 = 2C.

Tsheb them chaw nres tsheb chaw tsim khoom: Tus nqi siab them tsis yog 0% -100% ntawm tus nqi yog ua los ntawm kev them nyiaj tam sim no. Txoj kev them nqi tsim nyog tau muab faib ua peb theem, theem 1: lub xeev them ua ntej; theem 2: siab tam sim no them tam sim no; theem 3: tsis tu ncua voltage them.

Tsheb them chaw nres tsheb chaw tsim khoom: Theem 1 pre-them them ua lub luag haujlwm tiv thaiv lub roj teeb ntawm tes, theem 2 yog qhov peb hu rau theem siab them nqi, lub zog ntau ntawm cov txheej txheem no feem ntau yog 20% ​​-80%; theem 3 qhov kev them nyiaj tas li yog tsom rau kev txwv qhov hluav taws xob, tiv thaiv lub roj teeb ntawm tes los ntawm qhov hluav taws xob ntau dhau, uas tuaj yeem ua rau cov qauv roj teeb puas.

1, Tsheb them chaw nres tsheb chaw tsim khoom: kev them ceev ceev yuav tsum tau txhim kho lub zog ntawm qhov kawg them thiab lub roj teeb them / tso tawm ntau

Muaj ob txoj hauv kev them nyiaj tseem ceeb rau EVs: DC them sai sai thiab AC qeeb them.

Lub tsheb them chaw nres tsheb cov chaw tsim khoom: AC qeeb them nqi sib raug rau qhov chaw them nyiaj hauv tsev lossis cov chaw nres tsheb hauv zej zog, them lub zog me me los ntawm ob peb kilowatts mus rau kaum ob kilowatts, feem ntau yuav siv sijhawm 8-10 teev kom them tag nrho. AC qeeb them nyiaj siv 220V AC fais fab ncaj qha los ntawm daim phiaj, thiab hloov mus rau DC lub zog los ntawm AC / DC converter hauv lub on-board charger OBC los muab EV roj teeb. Lub tsheb them chaw nres tsheb chaw tsim khoom: Vim tias lub zog them qis dua, lub zog ntawm AC / DC converter ua rau hauv lub nkoj OBC feem ntau qis dua, thiab tus nqi qis dua.

Lub tsheb them chaw nres tsheb cov chaw tsim khoom: DC them sai sai feem ntau sib haum rau cov xwm txheej them nyiaj ntawm txoj kev tsheb / mus ntev, qhov twg lub zog ncav cuag ntau pua kilowatts thiab siv sijhawm li 1-2 teev xwb kom them tag nrho. Lub ntsiab lus ntawm DC them ceev ceev yog hloov lub zog siab AC / DC mus rau qhov chaw them nqi ceev, qhov twg DC charging ncej hloov AC lub zog los ntawm daim phiaj mus rau lub zog siab DC lub zog los ntawm lub rectifier kom them lub tsheb roj teeb ncaj qha. Lub zog siab tshaj plaws ntawm kev them nyiaj ceev tuaj yeem ncav cuag 350kW lossis txawm tias 480kW, thiab lub sijhawm them nyiaj ceev ceev yuav tsum raug txo kom tsawg dua 30 feeb, thiab yav tom ntej nws yuav raug compressed tsawg dua kaum feeb.
