▍ 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.

Kupararira kwekupisa kwemodule kunosangana nematanho anotevera: Kuwedzera kupisa mushure mekushandiswa kwesero kupisa, cell thermal runaway uyezve module thermal runaway. Thermal kutiza kubva musero rimwe chete hakuna simba; zvisinei, apo kupisa kunopararira kune mamwe masero, kupararira kuchaita kuti domino iite, zvichiita kuti kupisa kwemhepo kunopera kwemodule yose, kusunungura simba guru. Mufananidzo 1 unoratidza mhedzisiro yekupisa kwekumhanya bvunzo. The module iri pamoto nekuda kusingadzivisiki propagation.The kupisa conductivity mukati sero achava akasiyana maererano siyana nzira. Iyo coefficient yekupisa conductivity ichave yakakwirira munzira inofananidzwa neiyo roll core yesero; ukuwo gwara rakati kwara kune roll core rine yakaderera conductivity. Naizvozvo kupisa kupararira kubva kudivi kuenda kune rimwe divi pakati pemasero kunokurumidza kupfuura zvazvinoita kuburikidza nematabhu kuenda kumaseru. Nokudaro kuparadzira kunogona kuonekwa sekuparadzira kwe-mwe-dimension. Sezvo mabhatiri mamodule akagadzirirwa epamusoro simba density, nzvimbo iri pakati pemasero iri kuita diki, izvo zvinozowedzera kupisa kupararira. Naizvozvo, kudzvanya kana kuvhara kupararira kwekupisa mumodule kuchaonekwa senzira inoshanda yekudzikisa njodzi.
Tinokwanisa kudzora kupisa kunotiza tichishingaira kana kungoita zvishoma.Active thermal spread suppression is most based on thermal management system, se:1)Seta pombi dzinotonhorera pasi kana mukati memodule, uye uzadze nemvura inotonhorera. Kuyerera kwemvura inotonhodza kunogona kuderedza kupararira.2)Gadzirisa mapaipi ekudzima moto pamusoro pemodule. Kana paine kupisa kunotiza, tembiricha yakakwira gasi inoburitswa kubva mubhatiri ichaita kuti mapaipi apfapfaize kunze kwekudzima kuti adzvanyire kupararira.Zvisinei, manejimendi ekupisa anoda zvimwe zvikamu, zvinotungamira kumutengo wakakwira uye kuderera kwesimba remagetsi. Pane zvakare mukana wekuti manejimendi system inogona kusashanda.
