Kev tawm tsam ntawm rab phom tawm feem ntau yog 2kΩ, uas yog siv rau kev nyab xeeb tawm tom qab them nyiaj tiav. Tus nqi tiv thaiv no yog tus qauv tus nqi, uas yog siv los txheeb xyuas lub xeev tawm thiab ua kom muaj kev nyab xeeb.
Cov lus piav qhia ntxaws:
Lub luag hauj lwm ntawm qhov tso tawm resistor:
Lub luag haujlwm tseem ceeb ntawm kev tawm qhov hluav taws xob yog kom muaj kev nyab xeeb tso tawm cov nqi hauv lub capacitor lossis lwm yam khoom siv hluav taws xob cia hauv rab phom tom qab them nyiaj tiav, kom tsis txhob muaj cov nqi seem los ntawm kev ua rau muaj kev phom sij rau tus neeg siv lossis khoom siv.
Txheem tus nqi:
Kev tawm tsam ntawm lubtso phomfeem ntau yog 2kΩ, uas yog tus qauv tus nqi hauv kev lag luam.
Discharge ID:
Qhov kev tiv thaiv tus nqi no yog siv nrog rau lwm cov circuits hauv cov phom them nyiaj los txheeb xyuas lub xeev tawm. Thaum cov hluav taws xob tawm hluav taws xob txuas nrog lub voj voog, cov pawg them nyiaj yuav raug txiav txim raws li lub xeev tawm thiab pib cov txheej txheem tawm.
Kev ruaj ntseg lav:
Qhov muaj nyob ntawm qhov tawm ntawm qhov hluav taws xob tiv thaiv kom ntseeg tau tias tom qab kev them nyiaj tiav, cov nqi hauv rab phom tau raug tso tawm kom nyab xeeb ua ntej tus neeg siv rub tawm rab phom them, zam kev raug mob xws li hluav taws xob poob siab.
Kev siv sib txawv:
Ntxiv nrog rau tus qauv tso tawm rab phom, muaj qee qhov tshwj xeeb daim ntawv thov, xws li BYD Qin PLUS EV's on-board charger, uas nws cov hluav taws xob tawm hluav taws xob tuaj yeem muaj lwm yam txiaj ntsig, xws li 1500Ω, nyob ntawm qhov tshwj xeeb tsim hluav taws xob thiab kev ua haujlwm.
Discharge identification resistor:
Qee cov phom tso tawm kuj muaj qhov tso tawm cov cim tiv thaiv sab hauv, uas, ua ke nrog lub micro hloov, tuaj yeem siv los xyuas kom meej tias lub xeev tawm tau nkag mus tom qab cov phom them raug txuas.
Cov lus sib piv ntawm cov nqi tsis kam ntawmtso phomhauv GB / T qauv
Tus qauv GB / T muaj cov kev cai nruj ntawm cov nqi tiv thaiv ntawm cov phom tua. Tus nqi tiv thaiv ntawm CC thiab PE yog siv los tswj qhov sib txuam ntawm kev tawm hluav taws xob thiab lub tsheb kom muaj kev nyab xeeb ntawm kev siv hluav taws xob.
Lus Cim: Cov phom tso tawm tsuas yog siv tau yog tias lub tsheb nws tus kheej txhawb nqa txoj haujlwm tawm.
Raws li Daim Ntawv Ntxiv A.1 ntawm nplooj ntawv 22 ntawm GB/T 18487.4, V2L tswj kev tsav Circuit Court thiab tswj txoj cai ntu ntawm A.1 tso rau pem hauv ntej cov kev cai tshwj xeeb rau qhov voltage thiab tam sim no ntawm paug.
Kev tawm sab nraud tau muab faib ua DC tawm thiab AC tawm. Peb feem ntau siv qhov yooj yim ib-theem 220V AC tso tawm, thiab cov lus pom zoo tam sim no yog 10A, 16A, thiab 32A.
63A qauv nrog peb-theem 24KW tso zis: tawm phom tsis kam nqi 470Ω
32A qauv nrog ib-theem 7KW tso zis: tawm phom tsis kam nqi 1KΩ
16A qauv nrog ib-theem 3.5KW tso zis: tawm phom tsis kam nqi 2KΩ
10A qauv nrog ib-theem 2.5KW tso zis: tawm phom tsis kam nqi 2.7KΩ
