Cov chaw tsim khoom siv them lub tsheb hais txog: 800V High Voltage Charging System

Cov chaw tsim khoom siv them lub tsheb: Lub tshuab hluav taws xob 800V high-voltage + super fast charging rau cov tsheb fais fab tuaj yeem ua tiav lub sijhawm them ntawm 10 feeb thiab ntau yam ntawm 300 kilometers, uas tuaj yeem daws qhov kev ntxhov siab ntawm kev rov ua dua tshiab, thiab xav tias yuav dhau los ua txoj hauv kev tseem ceeb ntawm kev them ceev. Cov tuam txhab tsheb hauv tsev thiab txawv teb chaws twb tau ua cov qauv tsim nyog, thiab ntau tus qauv 800V yuav raug tsim ntau hauv xyoo 2022. Tab sis nruab nrog 800V high-voltage platform tsheb them hauv kev them nqi ib txwm, kev them ceev tsis yog txog li qhov xav tau, tsis tuaj yeem ua tiav super fast charging, yog li qhov kawg ntawm cov saw hlau kev lag luam yuav tsum tau hloov kho dua tshiab nrog rau qhov kawg ntawm lub tsheb, ntau ntu ntawm txoj kev yuav tau txais txiaj ntsig.

Ua ntej, qhov them hluav taws xob siab yog dab tsi

Cov chaw tsim khoom ntawm chaw them lub tsheb: Kev them ceev yog kev them ceev, chav ntsuas tuaj yeem them lub sijhawm (C). Qhov loj dua ntawm tus nqi them, lub sijhawm them luv dua.

Tus nqi them sib npaug (C) = tam sim no them (mA) / lub peev xwm ntsuas roj teeb (mAh)

Piv txwv li, yog tias lub peev xwm ntawm lub roj teeb yog 4000mAh thiab qhov them tam sim no ncav cuag 8000mAh, qhov them multiplier yog 8000/4000 = 2C.

Cov chaw tsim khoom ntawm chaw them tsheb: Kev them nqi siab tsis yog 0% -100% ntawm tus nqi yog ua los ntawm kev them tam sim no siab. Hom kev them nqi tsim nyog tau muab faib ua peb theem, theem 1: lub xeev them ua ntej; theem 2: kev them tam sim no siab; theem 3: kev them hluav taws xob tas li.

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

1, Lub chaw them nqi tsheb: kev them ceev ceev yuav tsum txhim kho lub zog ntawm qhov kawg them thiab lub roj teeb them / tso tawm ntau

Muaj ob txoj kev them nqi tseem ceeb rau EVs: DC them ceev thiab AC them qeeb.

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

Cov chaw tsim khoom siv them lub tsheb: DC them ceev feem ntau sib xws rau cov xwm txheej them ntawm txoj kev loj / kev mus ncig ntev, qhov twg lub zog ncav cuag ntau pua kilowatts thiab tsuas yog siv sijhawm 1-2 teev los them tag nrho. Lub ntsiab lus ntawm DC them ceev yog hloov AC / DC muaj zog siab mus rau qhov chaw them ceev, qhov twg DC them chaw hloov AC lub zog los ntawm lub grid mus rau hauv lub zog DC muaj zog siab los ntawm lub rectifier los them lub roj teeb tsheb ncaj qha. Lub zog siab tshaj plaws ntawm kev them ceev tuaj yeem ncav cuag 350kW lossis txawm tias 480kW, thiab lub sijhawm them ceev ceev yuav tsum raug txo kom tsawg dua 30 feeb, thiab yav tom ntej nws yuav raug nias kom tsawg dua kaum feeb.
