Hauv tebchaws United Kingdom, Lub Chaw Them Nqi Hluav Taws Xob rau Pej Xeem (PECI) yog ib lub network uas nthuav dav sai, uas tsom mus rau kev txhawb nqa kev siv cov tsheb fais fab (EVs) thiab txo cov pa roj carbon ntawm lub tebchaws. Txhawm rau kom ntseeg tau tias muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov chargers EV, ntau yam kev tiv thaiv, suav nrog kev siv PEN fault protection, tau tsim muaj hauv UK. PEN fault protection yog hais txog cov txheej txheem kev nyab xeeb uas koom ua ke rau hauv cov kab ke hluav taws xob ntawm EV chargers kom tiv thaiv kev phom sij, tshwj xeeb tshaj yog thaum muaj kev poob ntawm lub ntiaj teb tiv thaiv thiab kev sib txuas nruab nrab (PEN).
Ib qho tseem ceeb ntawm kev tiv thaiv qhov txhaum ntawm PEN yog qhov tseem ceeb rau kev ua kom ntseeg tau tias cov kev sib txuas ntawm lub zog nruab nrab thiab lub ntiaj teb tseem zoo thiab tau sib txuas hauv av. Yog tias muaj qhov txhaum ntawm PEN, qhov twg cov kev sib txuas ntawm lub zog nruab nrab thiab lub ntiaj teb raug cuam tshuam, cov txheej txheem tiv thaiv hauv cov chargers EV tau tsim los nrhiav thiab teb rau qhov txhaum tam sim ntawd, txo qhov kev pheej hmoo ntawm kev raug hluav taws xob thiab lwm yam xwm txheej hluav taws xob. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov ntsiab lus ntawm kev them EV, vim tias txhua qhov kev cuam tshuam hauv kev ncaj ncees ntawm hluav taws xob tuaj yeem ua rau muaj kev pheej hmoo loj rau cov neeg siv thiab cov khoom siv ib puag ncig.
Yuav kom ua tiav kev tiv thaiv qhov txhaum PEN zoo, cov cai lij choj hauv UK feem ntau xav kom siv cov Khoom Siv Tam Sim No (RCDs) thiab lwm yam khoom siv tiv thaiv tshwj xeeb. RCDs yog cov khoom tseem ceeb uas saib xyuas qhov tam sim no ntws los ntawm cov neeg ua haujlwm nyob thiab tsis muaj hluav taws xob, kom ntseeg tau tias muaj kev tsis sib npaug lossis qhov txhaum sai sai. Thaum pom qhov txhaum, RCDs yuav cuam tshuam cov khoom siv hluav taws xob sai sai, yog li tiv thaiv kev poob hluav taws xob thiab kev phom sij hluav taws.
Ntxiv mus, kev koom ua ke ntawm cov txheej txheem saib xyuas thiab kuaj mob siab heev hauv cov EV chargers tso cai rau kev tshawb pom lub sijhawm tiag tiag ntawm txhua yam teeb meem uas yuav tshwm sim, suav nrog PEN qhov yuam kev. Cov txheej txheem no feem ntau suav nrog cov algorithms zoo heev uas tuaj yeem txheeb xyuas qhov tsis sib xws hauv cov hluav taws xob ntws, qhia txog qhov ua yuam kev PEN lossis lwm yam kev txhawj xeeb txog kev nyab xeeb. Cov peev xwm tshawb pom thaum ntxov no ua rau muaj kev teb sai, kom ntseeg tau tias txhua qhov yuam kev raug daws sai sai kom tswj tau kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom siv them nqi.
Kev siv cov qauv thiab kev cai lij choj nruj yog lwm qhov tseem ceeb ntawm kev ua kom muaj kev tiv thaiv qhov txhaum PEN zoo hauv cov EV chargers thoob plaws UK. Cov koom haum tswj hwm, xws li Lub Tsev Kawm Ntawv Engineering thiab Technology (IET) thiab International Electrotechnical Commission (IEC), ua lub luag haujlwm tseem ceeb hauv kev tsim cov lus qhia thiab cov kev cai rau kev teeb tsa, kev ua haujlwm, thiab kev saib xyuas cov chaw them EV. Cov qauv no suav nrog ntau yam, suav nrog kev tsim hluav taws xob, kev xaiv khoom siv, kev coj ua teeb tsa, thiab kev tshuaj xyuas kev nyab xeeb tas mus li, txhua yam tsom mus rau kev txo cov kev pheej hmoo cuam tshuam nrog PEN qhov txhaum thiab lwm yam teeb meem hluav taws xob.
Zuag qhia tag nrho, cov kev ntsuas tiv thaiv qhov txhaum PEN hauv UK qhia txog lub teb chaws txoj kev cog lus los tswj cov qauv kev nyab xeeb siab hauv nws cov chaw them hluav taws xob EV uas loj hlob tuaj. Los ntawm kev muab qhov tseem ceeb rau kev siv cov kev ntsuas tiv thaiv zoo, cov qauv nruj, thiab cov txheej txheem saib xyuas siab heev, UK siv zog los txhawb kom muaj ib puag ncig zoo thiab txhim khu kev qha rau kev siv tsheb fais fab dav dav, yog li pab txhawb rau kev hloov pauv mus rau qhov chaw thauj mus los uas ruaj khov dua thiab zoo rau ib puag ncig.
Yog tias tseem muaj lus nug, thov koj xav tiv tauj pebtiv tauj peb.
