Khoom Description
Qhov kev pabcuam no, raws li GB / T 40432-2021 tus qauv, ua 7 pawg thiab 20+ kev ntsuas huab cua ntawm On-Board Chargers (OBCs), suav nrog kev caij tsheb kauj vab kub (-40℃txog 85 degree), damp tshav kub laus (95% RH), thiab overvoltage surges (1.5 zaug). Nws raug simulates 8-10 xyoo ntawm kev siv cov laus los xyuas qhov kev ua neej thiab kev nyab xeeb ntawm cov khoom siv hluav taws xob.

Kev Pabcuam Tom Qab
Nrog rau kev nce qib thoob ntiaj teb ntawm "Dual Carbon" cov hom phiaj, lub ntiaj teb tshiab lub zog tsheb muag tau tshaj 20 lab units hauv 2024, nrog rau Suav lag luam suav txog ntau dua 60%. Raws li cov ntsiab lus tseem ceeb txuas rau kab hluav taws xob thiab lub roj teeb, OBC yuav tsum tiv taus 1-2 lub sijhawm them txhua hnub ntawm qhov nruab nrab. Rau qee lub tsheb ua lag luam (piv txwv li, tsheb tavxij, caij- tsheb thauj neeg), qhov kev them nyiaj txhua hnub tuaj yeem ncav cuag 3-5 zaug. Kev hloov hluav taws xob ntau zaus ua rau kev laus ntawm cov khoom siv hluav taws xob sab hauv (xws li IGBTs, capacitors), ua rau nws yuav tsum tau xyuas kom muaj kev ntseeg tau ntev los ntawm kev sim ua kom ntev.
Peb Qhov Zoo
● GRGTEST muaj kev paub dhau los hauv kev ua haujlwm ntev thiab kev ntseeg siab rau cov khoom siv hluav taws xob hauv tsheb, suav nrog OBCs, ua raws li cov qauv hauv tebchaws thiab thoob ntiaj teb.
● Peb lub chaw soj nstuam tau nruab nrog cov chav ua haujlwm siab tshaj plaws, kev ntsuas kev vibration, thiab cov cuab yeej ntsuas hluav taws xob precision kom ntseeg tau tias muaj tseeb thiab rov ua dua.
● Peb muab cov ntawv tshaj tawm kev xeem nrog cov ntaub ntawv ntxaws ntxaws, txhawb peb cov neeg siv khoom hauv kev txhim kho cov khoom thiab cov txheej txheem ntawv pov thawj.
