Zviyero uye Chitupa Gwaro
Test mwero: GB31241-2014:Lithium ion maseru nemabhatiri anoshandiswa mumidziyo yemagetsi inotakurika - Chekuchengetedza zvinodiwa
Gwaro retifiketi: CQC11-464112-2015:Sekondari Bhatiri uye Bhatiri Pack Chengetedzo Yekuchengetedzeka Mitemo ye Inotakurika Electronic Devices
Background uye Zuva rekushandiswa
1. GB31241-2014 yakabudiswa musi wa5 Zvitath, 2014;
2. GB31241-2014 yakaitwa nemutemo musi wa1 Nyamavhuvhust, 2015.
3. Musi wa15 Gumiguru, 2015, Certification and Accreditation Administration yakapa chigadziriso chehunyanzvi pakuwedzera kuyedzwa mwero GB31241 yechikamu chakakosha che "bhatiri" redhiyo uye vhidhiyo michina, ruzivo rwemichina uye telecom terminal michina. Sarudzo iyi inoti mabhatiri e-lithium anoshandiswa muzvigadzirwa zviri pamusoro anofanirwa kuongororwa zvisina tsarukano maererano neGB31241-2014, kana kuwana chitupa chakasiyana.
Cherechedza: GB 31241-2014 chiyero chenyika chinomanikidzirwa. Zvese zvigadzirwa zve lithium bhatiri zvinotengeswa muChina zvinoenderana neGB31241 yakajairwa. Iyi chiyero ichashandiswa muzvirongwa zvitsva zvesampling yekuongorora kwenyika, purovhinzi uye yemunharaunda.

Zvinyorwa zvetifiketiinonyanya kugadzirirwa zvigadzirwa zvemagetsi zvefoni zvakarongerwa kuve zvisingasviki 18kg uye zvinogona kutakurwa nevashandisi. Mienzaniso mikuru ndeiyi inotevera. Zvigadzirwa zvemagetsi zvinotakurika zvakanyorwa pazasi hazvibatanidzi zvigadzirwa zvese, saka zvigadzirwa zvisina kunyorwa hazvisi hazvo zviri kunze kwechiyero chechiyero ichi.
Midziyo inopfekwa: Lithium-ion mabhatiri uye bhatiri mapaketi anoshandiswa mumidziyo inoda kusangana nezvinodiwa.

▍ Neiko MCM?
● Kuzivikanwa kwekodzero: MCM irabhoritari yeCQC yakagamuchirwa uye yeCESI yakagamuchirwa laboratori. Chirevo chebvunzo chakapihwa chinogona kushandiswa zvakananga kuCQC kana CESI chitupa;
● Rutsigiro rwehunyanzvi: MCM ine GB31241 yakakwana yemidziyo yekuongorora uye yakashongedzerwa nevanopfuura gumi vane hunyanzvi matekinoroji kuti vaite tsvakiridzo yakadzama pahunyanzvi hwekuyedza, chitupa, kuongorora fekitori uye mamwe maitiro, ayo anogona kupa akanyatso uye akagadziridzwa GB 31241 certification masevhisi epasi rose. vatengi.
Nekunyanya njodzi inokonzerwa ne-lithium-ion bhatiri inoitika, Vanhu vanonyanya kunetseka pamusoro pebheteri yekushisa inomhanya, sezvo kupisa kwemhepo kunoitika mune imwe sero kunogona kuparadzira kupisa kune mamwe masero, zvichiita kuti kuvharwa kwebheteri system yose.
Nechinyakare isu tinokonzeresa kutiza kwekupisa nekudziya, kupinza kana kuwandisa panguva yekuedzwa. Nekudaro, nzira idzi hadzigone kudzora kutiza kwekupisa musero yakatarwa, uye haigone kuitwa nyore panguva yekuyedzwa kwemabhatiri masisitimu. Munguva pfupi yapfuura vanhu vari kugadzira nzira nyowani yekukonzeresa kutiza kwekupisa. Iyo Propagation bvunzo mune itsva IEC 62619: 2022 muenzaniso, uye inofungidzirwa kuti nzira iyi ichave inoshandiswa zvakanyanya mune ramangwana. Chinyorwa ichi ndechekuzivisa dzimwe nzira itsva dziri kutsvagirwa.
Laser mwaranzi kupisa nzvimbo diki ine simba rakawanda laser pulse. Kupisa kuchaitwa mukati mezvinhu. Laser radiation inoshandiswa zvakanyanya munzvimbo dzekugadzirisa zvinhu, senge welding, kubatanidza uye kucheka. Kazhinji kune marudzi e laser sezvinotevera:
Kuve neCT scan pane isina kukonzeresa sero, zvinogona kuwanikwa kuti hapana chimiro chesimba kunze kwegomba riri pamusoro. Zvinoreva kuti laser inotungamira, uye yakakwirira-simba, uye nzvimbo yekudziya ndiyo chaiyo. Saka laser inzira yakanaka yekuyedza. Tinogona kudzora shanduko, uye kuverenga iyo yekupinza uye kubuda simba nemazvo. Zvichakadaro laser ine zvakanakira kudziyisa uye pinning, sekumhanyisa kupisa, uye zvakanyanya kudzoreka. Laser ine zvimwe zvakanakira se:
