Iwo 5 ane chiremera zvakanyanya zviyero zvekuchengetedza bhatiri (yepasi-yepasi zviyero)

Lithium-ion bhatirimasisitimu akaomarara emagetsi emagetsi uye emagetsi masisitimu, uye kuchengetedzwa kwebhatiri paki kwakakosha mumotokari dzemagetsi.China's "Electric Vehicle Safety Requirements", iyo inotaura zvakajeka kuti bhatiri system inodiwa kuti irege kubata moto kana kuputika mukati me5 maminetsi mushure mekupisa kwekupisa kwebhatiri monomer, zvichisiya nguva yekupukunyuka yakachengeteka kune vanogara.

(1) Kuchengetedzwa kwekupisa kwemabhatiri emagetsi

Tembiricha yakadzikira inogona kukonzeresa kusashanda zvakanaka kwebhatiri uye kukuvara kunogona kuitika, asi kazhinji hazvikonzere njodzi.Zvisinei, kuwandisa (yakanyanya kukwira voltage) kunogona kutungamirira mukuparara kwecathode uye electrolyte oxidation.Kuwedzera-kuburitsa (yakanyanya kuderera voltage) kunogona kutungamirira mukuora kweiyo yakasimba electrolyte interface (SEI) pane anode uye inogona kutungamira kune oxidation yefoiri yemhangura, zvichiwedzera kukanganisa bhatiri.

(2) IEC 62133 yakajairika

IEC 62133 (Safety test standard yelithium-ion mabhatiri nemaseru), chinhu chekuchengetedza chinodiwa pakuyedza mabhatiri echipiri uye maseru ane alkaline kana asiri acidic electrolytes.Inoshandiswa kuyedza mabhatiri anoshandiswa mumagetsi anotakurika uye mamwe maapplication, kugadzirisa kemikari nemagetsi njodzi uye nyaya dzemakanika dzakadai sekudengenyeka uye kuvhunduka zvinogona kutyisidzira vatengi uye nharaunda.

(3)UN/DOT 38.3

UN / DOT 38.3 (T1 - T8 miedzo uye UN ST / SG / AC.10/11 / Rev. 5), kuvhara mabheti ose ebheteri, lithium metal cell uye mabhatiri ekufambisa kuchengetedzwa kwekuchengetedza.Chiyero chekuyedza chine bvunzo sere (T1 - T8) yakatarisana nenjodzi dzekufambisa.

(4) IEC 62619

IEC 62619 (Safety Standard yeSekondari Lithium Mabhatiri uye Bhatiri Packs), chiyero chinotsanangura zvinodikanwa zvekuchengetedza mabhatiri mumagetsi uye mamwe maindasitiri maapplication.Zvinodiwa zvebvunzo zvinoshanda kune zvese zvakamira uye zvine simba application.Mamiriro ekushandisa anosanganisira nharembozha, magetsi asingapindiki (UPS), masisitimu emagetsi ekuchengetera simba, shanduko yekushandisa, simba rekukurumidzira uye mamwe maapplication akafanana.Zvishandiso zvine simba zvinosanganisira forklift, ngoro dzegorofu, otomatiki inotungamirwa mota (AGVs), njanji, uye ngarava (kunze kwemumugwagwa mota).

(5)UL 2580x

UL 2580x (UL Safety Standard yeMagetsi Vehicle Batteries), inosanganisira akati wandei bvunzo.

High Current Battery Short Circuit: Iyi bvunzo inoitiswa pasample yakachajwa zvizere.Sample ipfupi-yakatenderedzwa ichishandisa yakazara dunhu kuramba ye ≤ 20 mΩ.Spark ignition inoona kuvepo kwekupisa kwegasi mumuenzaniso uye hapana zviratidzo zvekuputika kana moto.

Battery Crush: Mhanya pamuenzaniso wakachajiswa zvizere uye tevedzera mhedzisiro yekuparara kwemotokari paEESA kusatendeseka.Sezvakaita bvunzo pfupi yedunhu, spark ignition inoona kuvepo kwekupisa kwegasi mumuenzaniso uye hapana chinoratidza kuputika kana moto.Hapana magasi ane chepfu anoburitswa.

Battery Cell Squeeze (Yakatwasuka): Mhanya pamuenzaniso wakachajwa.Simba rinoshandiswa mukudzvanya bvunzo rinofanira kuganhurwa kusvika ka1000 kurema kwesero.Spark ignition yekuona yakafanana neiyo inoshandiswa muyedzo yekusvina.

(6) Zvekuchengetedza Zvinodiwa zveMagetsi Mota (GB 18384-2020)

Zvekuchengetedza Zvinodikanwa zveMotokari dzeMagetsi" chiyero chenyika chePeople's Republic of China chakaitwa muna Ndira 1, 2021, icho chinonongedza zvinodiwa zvekuchengetedza uye nzira dzekuyedza dzemotokari dzemagetsi.
