▍ Chii chinonzi CTIA CERTIFICATION?

CTIA, chidimbu cheCellular Telecommunications uye Internet Association, isangano risingabatsiri purofiti rakavambwa muna 1984 nechinangwa chekuvimbisa kubatsirwa kwevashandisi, vagadziri uye vashandisi. CTIA ine vese vashandisi veUS nevagadziri kubva kunharembozha redhiyo masevhisi, pamwe neasina waya data masevhisi uye zvigadzirwa. Inotsigirwa neFCC (Federal Communications Commission) neCongress, CTIA inoita chikamu chikuru chemabasa nemabasa aishandiswa kuitwa nehurumende. Muna 1991, CTIA yakagadzira isina rusaruro, yakazvimiririra uye yepakati yekuongorora chigadzirwa uye certification system yeindasitiri isina waya. Pasi pehurongwa uhu, zvese zvigadzirwa zvisina waya mugiredhi revatengi zvinotora bvunzo dzekutevedzera uye izvo zvinoenderana nezvinodiwa zvichapihwa kushandisa CTIA yekumaka uye kurova masherufu ezvitoro zvemusika wekuNorth America wekutaurirana.

CATL (CTIA Authorized Testing Laboratory) inomiririra maLab akatenderwa neCTIA kuti iongororwe uye iongororwe. Mishumo yekuyedza yakapihwa kubva kuCATL inotenderwa ese neCTIA. Nepo mamwe marepoti ekuyedza nemhedzisiro kubva kune asiri-CATL zvisingazo zivikanwa kana kutadza kuwana CTIA. CATL yakatenderwa neCTIA inosiyana mumaindasitiri uye zvitupa. CATL chete iyo inokodzera kuyedza kutevedzera bhatiri uye kuongororwa inokwanisa kuwana chitupa chebhatiri chekutevedzera IEEE1725.

▍CTIA Battery Testing Standards

a) Certification Inodiwa yeBattery system Kutevedzera kuIEEE1725- Inoshanda kune Battery Systems nesero rimwe chete kana akawanda maseru akabatana akafanana;

b) Certification Inodiwa yeBattery system Kutevedzera kuIEEE1625- Inoshanda kuBattery Systems ine akawanda maseru akabatana mukufanana kana mune ese ari maviri akafanana uye akatevedzana;

Mazano anodziya: Sarudza pamusoro petifiketi zviyero nemabhatiri anoshandiswa munharembozha nemakomputa. Usashandise zvisirizvo IEE1725 kumabhatiri munharembozha kana IEEE1625 kumabhatiri ari mumakombuta.

▍Nei MCM?

●Hard Technology:Kubva 2014, MCM yanga ichipinda bhatiri pack musangano unoitwa neCTIA muUS gore rega, uye inokwanisa kuwana yazvino gadziriso uye kunzwisisa maitiro matsva emitemo nezveCTIA nenzira inokurumidza, yakarurama uye inoshanda.

●Qualification:MCM iCATL inotenderwa neCTIA uye inokwanisa kuita zvese zvine chekuita nechitupa kusanganisira kuyedza, kuongorora fekitori uye kurodha mushumo.

Parizvino, njodzi dzakawanda dzekuchengetedza mabhatiri e-lithium-ion dzinoitika nekuda kwekukundikana kwekuchengetedzwa kwedunhu, izvo zvinoita kuti bhatiri inopisa inopisa uye inokonzera moto uye kuputika. Naizvozvo, kuti uone kushandiswa kwakachengeteka kwelithium bhatiri, dhizaini yekudzivirira yedunhu inonyanya kukosha, uye marudzi ese ezvikonzero zvinokonzeresa kutadza kwe lithium bhatiri zvinofanirwa kuverengerwa. Pamusoro pemaitiro ekugadzira, kutadza kunonyanya kukonzerwa nekuchinja kwekunze kwemamiriro ekunze, sekuwedzeredza-chaji, kuburitsa zvakanyanya uye tembiricha. Kana aya maparamendi akatariswa munguva chaiyo uye anoenderana matanho ekudzivirira achatorwa kana achinja, kuitika kwekupisa kwekupisa kunogona kudziviswa. Kuchengetedza dhizaini ye lithium bhatiri kunosanganisira zvinhu zvakawanda: kusarudzwa kwesero, kugadzirwa kwemaitiro uye kushanda kwekuchengetedza dhizaini yeBMS.Kune zvinhu zvakawanda zvinokanganisa kuchengetedzwa kwesero umo kusarudzwa kwesero zvinhu ndiyo nheyo. Nekuda kweakasiyana emakemikari zvivakwa, kuchengetedza kunosiyana mune akasiyana cathode zvinhu zve lithium bhatiri. Semuenzaniso, lithium iron phosphate yakaita seolivine, iyo inenge yakagadzikana uye isiri nyore kudonha. Lithium cobaltate uye lithium ternary, zvisinei, akaturikidzana chimiro chiri nyore kudonha. Separator kusarudzwa kunokoshawo zvikuru, sezvo kushanda kwayo kwakabatana zvakananga nekuchengetedzwa kwesero. Naizvozvo pakusarudzwa kwesero, kwete mishumo yekuona chete asiwo maitiro ekugadzirwa kwemugadziri, zvinhu uye maparamendi azvo zvinotariswa. Insulation pakati pesero uye yakavharirwa; Insulation pakati pedanda tabs uye yakavharirwa; PCB yemagetsi spacing uye creepage kureba, yemukati wiring dhizaini, dhizaini yekugadzika, nezvimwe.
