M'dziko la ma charger agalimoto yamagetsi (EV), chitetezo ndi kudalirika ndizofunikira kwambiri. Chifukwa chake, miyezo yamakampani ndi ziphaso zimagwira ntchito yofunika kwambiri powonetsetsa kuti ma EV charger akukwaniritsa zofunikira zina zachitetezo. Zitsimikiziro ziwiri zomwe zimapezeka kwambiri ku North America ndi satifiketi ya UL ndi ETL. M'nkhaniyi, tiwona kufanana ndi kusiyana pakati pa ziphaso ziwirizi ndikufotokozera chifukwa chake zili zofunika kwa opanga ma charger a EV ngati Sichuan Weiyu Electric Co., Ltd.
Kodi UL ndi ETL Certification ndi chiyani?
Underwriters Laboratories (UL) ndi Electrical Testing Laboratories (ETL) onse ndi Nationally Recognized Testing Laboratories (NRTLs) omwe amayesa ndikutsimikizira zinthu zamagetsi kuti zitetezeke. Ma NRTL ndi mabungwe odziyimira pawokha ozindikiridwa ndi Occupational Safety and Health Administration (OSHA) omwe amayesa zinthu ndi ziphaso kuti atsimikizire kuti zinthuzo zikukwaniritsa mfundo zina zachitetezo.
UL ndi kampani yotsimikizira zachitetezo padziko lonse lapansi yomwe imayesa ndikutsimikizira zinthu zosiyanasiyana, kuphatikiza ma charger a EV. ETL, kumbali ina, ndi bungwe loyesa zinthu ndi certification lomwe lili m'gulu la EUROLAB, kampani yotsimikizira mayiko osiyanasiyana, kuyang'anira, kuyesa, ndi ziphaso. Ma certification a UL ndi ETL amadziwika kwambiri ndikuvomerezedwa ku North America komanso padziko lonse lapansi.
Kodi pali Kusiyana kotani pakati pa UL ndi ETL Certification?
Ngakhale ziphaso za UL ndi ETL zimadziwika ngati umboni wachitetezo chazinthu, pali kusiyana pakati pa ziphaso ziwirizi. Chimodzi mwa kusiyana kwakukulu ndi njira yoyesera. UL ili ndi malo ake oyesera ndipo imayesa zonse m'nyumba. ETL, kumbali ina, imapanga mayeso ake ku ma lab odziyimira pawokha. Izi zikutanthauza kuti zinthu zotsimikizika za ETL zitha kuyesedwa m'ma laboratories osiyanasiyana, pomwe zotsimikizika za UL zidayesedwa m'malo a UL.
Kusiyana kwina pakati pa certification za UL ndi ETL ndi mulingo woyeserera wofunikira. UL ili ndi zofunikira zolimba kuposa ETL pamagawo ena azogulitsa, koma osati zonse. Mwachitsanzo, UL imafuna kuyesedwa kwakukulu kwazinthu zomwe zimagwiritsidwa ntchito m'malo oopsa, monga m'malo okhala ndi mpweya woyaka kapena fumbi. Mosiyana ndi izi, ETL ingafunike kuyesa pang'ono pamagulu ena azinthu, monga zowunikira.
Ngakhale pali kusiyana kumeneku, ma certification a UL ndi ETL amadziwika ngati umboni wotsimikizika wachitetezo chazinthu ndi mabungwe olamulira ndi ogula chimodzimodzi. Chisankho cha satifiketi yomwe mungatsate nthawi zambiri chimatengera zinthu monga mtengo, zofunikira zoyezetsa, ndi zosowa zenizeni za chinthu chomwe chikutsimikiziridwa.
Chifukwa chiyani Zitsimikizo za UL ndi ETL zili Zofunikira kwa Opanga ma EV Charger?
Ma charger a EV ndi zida zamagetsi zovuta zomwe zimafunikira kuyesedwa kolimba ndi chiphaso kuti zitsimikizire chitetezo chawo komanso kudalirika. Zitsimikizo zonse za UL ndi ETL ndizofunikira kwa opanga ma charger a EV monga Sichuan Weiyu Electric Co., Ltd. chifukwa amapereka chitsimikizo kwa makasitomala kuti zinthu zathu zayesedwa paokha ndikutsimikiziridwa kuti zikwaniritse miyezo ina yachitetezo.
Kuphatikiza apo, kukhala ndi satifiketi ya UL kapena ETL kumathanso kukhala chofunikira pakugulitsa zinthu m'misika ina kapena kwa makasitomala ena. Mwachitsanzo, matauni ena kapena mabungwe aboma angafunike kuti ma charger a EV akhale ovomerezeka a UL kapena ETL asanayikidwe m'malo opezeka anthu onse. Momwemonso, makasitomala ena amalonda, monga makampani oyang'anira katundu, angafunike kuti zinthu zikhale zovomerezeka ndi UL kapena ETL asanaganize zogula.
Potsatira satifiketi ya UL kapena ETL pama charger athu a EV, Sichuan Weiyu Electric Co., Ltd. ikuwonetsa kudzipereka kwathu pachitetezo chazinthu ndi kudalirika. Timamvetsetsa kuti ma EV charger ndi gawo lofunikira lomwe liyenera kukhala lodalirika komanso lotetezeka kwa ogwiritsa ntchito komanso chilengedwe.
Mapeto
Ziphaso za UL ndi ETL ndizofunikira kwa kampani iliyonse yomwe imapanga zinthu zamagetsi, kuphatikiza ma charger a EV. Ngakhale pali kusiyana pakati pa certification ziwirizi, zonse zimadziwika ngati umboni wotsimikizika wachitetezo chazinthu komanso kudalirika. Kwa opanga ma charger a EV
