▍ 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, yakazvimirira uye nechepakati chekuongorora chigadzirwa uye certification sisitimu 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 aedze uye aongorore.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 pechitupa zviyero nemabhatiri anoshandiswa munharembozha nemakomputa.Usashandise zvisirizvo IEE1725 yemabhatiri munharembozha kana IEEE1625 yemabhatiri mumakomputa.

▍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.

Musi waMbudzi 27, 2023, “UN Manual of Tests and Criteria” (Rev. 8) yakaburitswa zviri pamutemo pawebhusaiti yeUnited States."UN Manual of Tests and Criteria" (Rev. 8) inogamuchira kudzokororwa kwakaitwa nechikamu che11 cheUnited Nations TDG uye GHS Expert Committee pa "UN Manual of Tests and Criteria" (Rev. 7) uye Amendment yayo 1 Sechiyedzo chekutanga chekutakura kwekuchengetedza kwebheteri, "UN Manual of Tests and Criteria" (Rev. 8) yakawedzera chikamu chitsva che 38.3.3.2 "Kuedzwa kwemasero e-sodium ion nemabhatiri", uye panguva imwe chete yakawedzera zvinyorwa zvakasununguka zvine chokuita ne mabhatiri e-sodium-ion muUN "Kurudziro pamusoro pekutakura zvinhu zvine ngozi" (TDG) Rev. 23: UN 3551 uye UN 3522.
T.1: Altitude simulation (sero nebhatiri)
Masero ekuyedza uye mabhatiri anozochengetwa nekudzvanywa kwe11.6 kPa kana kushoma kweanenge maawa matanhatu pakupisa kwe ambient (20±5℃)
Masero ekuedzwa nemabhatiri anofanira kuchengetwa kweanenge maawa matanhatu patembiricha yekuyedza yakaenzana ne72 ℃ uye -40 ℃.Iyi nzira inofanirwa kudzokororwa kusvika gumi ese apera.
Masero nemabhatiri akachengetedzwa zvakasimba papuratifomu yemuchina wekuzunguza, nekudedera kuve sinusoidal waveform ine logarithmic sweep pakati pe7 Hz ne200 Hz, uye amplitude pa 0.8mm, sero uye bhatiri diki rinotakura kukwirisa kwepamusoro kwe. 8 gn, uye yebhatiri hombe paki iyo yakanyanya kukwirisa ye2 gn.
