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.
| Electronic chigadzirwa chikamu | Mienzaniso yakadzama yemhando dzakasiyana dzezvigadzirwa zvemagetsi |
| Portable office products | notebook, pda, nezvimwewo. |
| Mobile communications products | nharembozha, nhare isina tambo, Bluetooth headset, walkie-talkie, nezvimwe. |
| Inotakurika odhiyo uye vhidhiyo zvigadzirwa | inotakurika terevhizheni, inotakurika mutambi, kamera, vhidhiyo kamera, nezvimwe. |
| Zvimwe zvinotakurika zvigadzirwa | electronic navigator, digital photo frame, game consoles, e-books, etc. |
▍ 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.
Kumanikidza kuburitsa kuyedzwa chinhu chekuyedza kuchengetedzwa kwekubuda. Kazhinji sero yakaedzwa inoburitswa mu1 IA ye90 min. Mufananidzo 1 ichati yekumanikidza kuburitsa kuyedzwa kubva kurudzi rwe lithium-ion bhatiri cell. Kusiyana neyakajairika yakanakira modhi (sezvinoratidzwa mumufananidzo 2), iyo voltage uye yazvino inochinja. Saka isu tinoedza kuongorora mukuru kuseri kwechati.
Zvinoenderana nemaitiro emagetsi, tinogona kupatsanura nzira yekuburitsa mumatanho matatu. Muchikamu chekutanga, voltage inodonha kubva pa3V kusvika ku0.65V. Muchikamu chechipiri, magetsi ari kutenderera 0.65V kusvika 0.5V. Iyo voltage inomira kudonha, uye pane kuchinja. Muchikamu chechitatu, voltage inodonha kusvika ku0V, uye hapana kuchinja. Apa voltage inoreva musiyano unogona kuitika pakati pe anode ne cathode.
Voltage inodzikira nekuramba ichibuda. Izvi zvinodaro nekuti mukana weiyo negative pole unoenda kumusoro uye iyo yepositive pole inodzika, uye li-ion inobuda kubva kune negative pole kuenda kune yakanaka pole. Sezvo bvunzo inoshandisa 1C ikozvino, voltage inodonha pasi nekukurumidza. Iyo SEI firimu inogona kuputswa mukuita uku, ichigadzira gasi uye kupisa.
Negative pole inogoneka inowedzera kusvika yakawandisa inokonzeresa kuti foil yemhangura inyunguduke. Sezvo paine kabhoni jasi, yakakwira pamusoro pekugona inodiwa kukonzeresa foil yemhangura kunyungudika, nekuda kwe-cu-ion kuendesa chaji yemagetsi. Mune danda rakashata, foil yemhangura inonyungudutswa uye oxidized kuCu + uye ipapo Cu2 + uye idzi cu-ion inopinda kuburikidza nefirimu yakasiyana kusvika kune yakanaka pole, neCu2 + redox kuCu +, uyezve redox kumhangura, ichiisa padanda rakanaka.
