▍Kodi CB Certification ndi chiyani?

IECEE CB ndiye njira yoyamba yapadziko lonse lapansi yovomerezera malipoti oyesa chitetezo cha zida zamagetsi.NCB (National Certification Body) ifika pa mgwirizano wamayiko osiyanasiyana, womwe umathandizira opanga kuti apeze ziphaso zadziko kuchokera kumayiko ena omwe ali mamembala pansi pa dongosolo la CB potengera kusamutsa chimodzi mwa ziphaso za NCB.

Satifiketi ya CB ndi chikalata chovomerezeka cha CB choperekedwa ndi NCB yovomerezeka, chomwe ndikudziwitsa NCB ina kuti zitsanzo zomwe zayesedwa zikugwirizana ndi zomwe zikufunika.

Monga mtundu wa lipoti lokhazikika, lipoti la CB limalemba zofunikira kuchokera ku IEC wamba ndi chinthu.Lipoti la CB silimangopereka zotsatira za mayeso onse ofunikira, kuyeza, kutsimikizira, kuyang'anira ndi kuwunika momveka bwino komanso mosadziwika bwino, komanso kuphatikiza zithunzi, chithunzi chozungulira, zithunzi ndi malongosoledwe azinthu.Malinga ndi lamulo la CB scheme, lipoti la CB siligwira ntchito mpaka litapereka satifiketi ya CB palimodzi.

▍Nchifukwa chiyani timafunikira CB Certification?

1. Chindunjilykuzindikirazedi or kuvomerezaedmwamembalamayiko

Ndi satifiketi ya CB ndi lipoti la mayeso a CB, malonda anu amatha kutumizidwa kumayiko ena mwachindunji.

1. Sinthani kumayiko ena ziphaso

Satifiketi ya CB imatha kusinthidwa mwachindunji kukhala satifiketi ya mayiko omwe ali mamembala ake, popereka satifiketi ya CB, lipoti la mayeso ndi lipoti loyesa kusiyana (ngati kuli koyenera) osabwereza mayeso, omwe angafupikitse nthawi yotsogolera yotsimikizira.

1. Onetsetsani Chitetezo cha Zamalonda

Mayeso a certification a CB amawona kugwiritsidwa ntchito moyenera kwa chinthucho komanso chitetezo chodziwikiratu chikagwiritsidwa ntchito molakwika.Chitsimikizo chotsimikizika chimatsimikizira zokhutiritsa zofunikira zachitetezo.

▍Chifukwa chiyani MCM?

● Ziyeneretso:MCM ndiye CBTL yoyamba yovomerezeka ya IEC 62133 yovomerezeka ndi TUV RH ku China.

● Chitsimikizo ndi kuthekera koyesa:MCM ili m'gulu loyamba loyesa ndi kutsimikizira chipani chachitatu pa muyezo wa IEC62133, ndipo yamaliza kuyesa kwa batri 7000 IEC62133 ndi malipoti a CB kwa makasitomala apadziko lonse lapansi.

● Thandizo laukadaulo:MCM ili ndi akatswiri opitilira 15 odziwika bwino pakuyesa malinga ndi muyezo wa IEC 62133.MCM imapatsa makasitomala chithandizo chokwanira, cholondola, chotsekeka chaukadaulo komanso zidziwitso zotsogola.

Mu 1800, katswiri wa sayansi ya zakuthambo wa ku Italy A. Volta anamanga mulu wa voltaic, womwe unatsegula chiyambi cha mabatire othandiza ndikufotokozera kwa nthawi yoyamba kufunika kwa electrolyte mu zipangizo zosungiramo mphamvu zamagetsi.Electrolyte imatha kuwonedwa ngati yosanjikiza pakompyuta ndi ion-conducting mu mawonekedwe amadzimadzi kapena olimba, oyikidwa pakati pa ma elekitirodi oyipa ndi abwino.Panopa, electrolyte kwambiri patsogolo amapangidwa Kusungunuka olimba lifiyamu mchere (mwachitsanzo LiPF6) mu sanali amadzimadzi organic carbonate zosungunulira (mwachitsanzo EC ndi DMC).Malinga ndi mawonekedwe a cell ndi kapangidwe kake, ma electrolyte nthawi zambiri amakhala 8% mpaka 15% ya kulemera kwa selo.Kuonjezera apo, kuyaka kwake ndi kutentha kwapakati pa -10 ° C mpaka 60 ° C kumalepheretsa kwambiri kusintha kwa mphamvu ya batri ndi chitetezo.Choncho, njira zatsopano za electrolyte zimaonedwa kuti ndizofunikira kwambiri pa chitukuko cha m'badwo wotsatira wa mabatire atsopano.Ofufuza akugwiranso ntchito kuti apange machitidwe osiyanasiyana a electrolyte.Mwachitsanzo, kugwiritsa ntchito zosungunulira fluorinated kuti angathe kukwaniritsa imayenera lifiyamu zitsulo njinga, organic kapena zosawerengeka olimba electrolytes kuti phindu makampani galimoto ndi "olimba boma mabatire" (SSB).Chifukwa chachikulu ndi chakuti ngati electrolyte olimba m'malo choyambirira madzi electrolyte ndi diaphragm, chitetezo, limodzi mphamvu kachulukidwe ndi moyo wa batire akhoza kwambiri bwino.Kenaka, timafotokozera mwachidule momwe kafukufuku wafukufuku wa electrolyte olimba ndi zipangizo zosiyanasiyana.
Ma electrolyte olimba a inorganic akhala akugwiritsidwa ntchito m'zida zosungiramo mphamvu zamagetsi zamagetsi, monga mabatire ena otenthetsera kwambiri a Na-S, Na-NiCl2 mabatire ndi mabatire oyambira a Li-I2.Kale mu 2019, Hitachi Zosen (Japan) adawonetsa batire la thumba lolimba kwambiri la 140 mAh kuti ligwiritsidwe ntchito mumlengalenga ndikuyesedwa pa International Space Station (ISS).Batire iyi imapangidwa ndi sulfide electrolyte ndi zigawo zina za batri zosadziwika, zomwe zimatha kugwira ntchito pakati pa -40°C ndi 100°C.Mu 2021 kampaniyo ikubweretsa batire yolimba kwambiri ya 1,000 mAh.Hitachi Zosen akuwona kufunikira kwa mabatire olimba m'malo ovuta monga malo ndi zida zamafakitale zomwe zimagwira ntchito m'malo wamba.Kampaniyo ikukonzekera kuwirikiza kawiri mphamvu ya batri pofika chaka cha 2025. Koma mpaka pano, palibe mankhwala a batri olimba omwe angagwiritsidwe ntchito pamagalimoto amagetsi.
