▍ 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 mishumo yekuyedza uye zvabuda kubva kune vasiri-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 musangano webhatiri pack 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.

Panguva yekuchaja uye kuburitsa mabhatiri, kugona kuchave kwakakonzerwa nekuwedzeredza kunokonzerwa nekupikiswa kwemukati. Seyakakosha parameter yebhatiri, kuramba kwemukati kwakakodzera kutsvagisa yekuongorora kuparara kwebhatiri. Kupikiswa kwemukati kwebhatiri kune:
Ohm kupikisa kwemukati (RΩ) -Kupikisa kubva kumatebhu, electrolyte, separator uye zvimwe zvikamu.Charges transmission internal resistance (Rct) - The resistance of ions passing tabs uye electrolyte. Izvi zvinomiririra kuoma kwemaitiro ematabo. Kazhinji tinogona kuwedzera conductivity kuderedza kushorwa uku.Polarization Resistance (Rmt) ndiko kupikisa kwemukati kunokonzerwa nekuwanda kusaenzana kwe lithium ions pakati pe cathode uye anode. Polarization Resistance ichave yakakwirira mumamiriro ezvinhu akafanana nekuchaja mutembiricha yakaderera kana yakakwirira rated charge.Kazhinji tinoyera ACIR kana DCIR. ACIR ndiko kupikisa kwemukati kuyerwa mu1k Hz AC ikozvino. Uku kupikisa kwemukati kunozivikanwawo seOhm resistance. Iko kushomeka kweiyo data ndeyekuti haigone kuratidza zvakananga kuita kwebhatiri. DCIR inoyerwa nekumanikidzirwa nguva dzese munguva pfupi, umo voltage inoramba ichichinja. Kana iyo pakarepo ikozvino ndiri ini, uye shanduko yemagetsi munguva pfupi iri ΔＵ, maererano neOhm mutemo Ｒ＝ΔＵ／Ｉ Tinogona kuwana DCIR. DCIR haisi yeOm chete yemukati kuramba, asiwo kuchaja kutamisa kuramba uye polarization kuramba.Inogara ichinetsa patsvagurudzo yeDCIR yerithium-ion bhatiri. Imhaka yekuti kuramba kwemukati kwerithium-ion bhatiri idiki kwazvo, kazhinji ingori imwe mΩ. Zvichakadaro sechikamu chinoshanda, zvakaoma kuyera kupikisa kwemukati zvakananga. Kunze kwezvo, kupikisa kwemukati kunokonzerwa nemamiriro ekunze, senge tembiricha uye mamiriro ekuchaja. Pazasi pane zviyero zvataurwa nezve nzira yekuyedza DCIR.
