Global Trends muMagetsi Vehicle Battery Safety: Ongororo Yakadzama yeMaitiro Ezvino-zvino eChina uye Kuti Melamine Foam Inovandudza Sei Battery Pack Performance uye Kuchengeteka.
- GB38031-2025: Dudziro Yakakwana yeChina yeMagetsi Vehicle Battery Safety Standard
Iyo ichangobva kuburitswa yemagetsi mota yemagetsi bhatiri chiyero chekuchengetedza, GB38031-2025, ine chinangwa chekusimbisa kuchengetedzwa kwemabhatiri mapaketi uye kuve nechokwadi kuvimbika uye kugadzikana kwemotokari dzemagetsi pasi pemamiriro akasiyana. Iyi chiyero inotarisa pane akati wandei akakosha nzvimbo:
- Thermal Management: GB38031-2025 inoda kuti bhatiri mapaketi anofanirwa kuve neanoshanda ekupisa manejimendi system kudzivirira kupisa uye kuchengetedza nyaya. Iyo dhizaini inofanirwa kuve yakagadzikana kushanda munzvimbo dzakanyanyisa tembiricha.
- Mechanical Safety: Chiyero chinozivisa zvakaomesesa zvimiro zvemabhatiri packs kudzivirira kuvuza kana moto kana paitika kudhumhana.
- Kudzivirira Moto: Iyo yakajairwa inoraira kuti mabhatiri mapaketi anofanirwa kuve nehumwe hunyanzvi hwekudzivirira moto kudzivirira kupararira kwemoto kana kupisa kutiza panguva yemoto.
- Kuchengetedzwa Kwenzvimbo uye Kudzokorodza: GB38031-2025 inosimbisa kudzokororwa uye kukanganiswa kwezvakatipoteredza kwezvinhu zvebhatiri, kuve nechokwadi chekukuvara kushoma kwezvakatipoteredza kana bhatiri rasvika kumagumo ehupenyu hwaro.

- Kuenzaniswa kweInternational Standards: EU, US, Japan, uye China's Battery Safety Requirements
Kuti uwedzere kusimbisa ruzivo rwepasirese rwekuchengetedza bhatiri remotokari yemagetsi, chinyorwa ichi chinofananidza GB38031-2025 neEU (UN38.3), US (UL 2580), uye Japan (JIS D 0001) zviyero.

III. Kushandiswa kwakakosha kweMelamine Foam muBattery Thermal Management
Sezvo zvinodikanwa zvekuchengetedza mabhatiri emotokari yemagetsi zvichiramba zvichikwira, melamine foam, inoshanda yekudziya yekudzora zvinhu, iri kuiswa zvakanyanya mukugadzira bhatiri pack. Melamine furo inopa zvinotevera zvakanakira:
- Yakanakisa Thermal Insulation Performance:
Melamine foam ine a low thermal conductivity, kazhinji pakati 0.033 W/m·K uye 0.035 W/m·K, kunyatsodzivirira kupisa kwemukati nekunze kwebhatiri pack, kudzivirira kupisa kunotiza nekuda kwekupisa kwakanyanya. Inochengetedza kushanda kwakadzikama munzvimbo dzepamusoro-tembiricha, kuve nechokwadi chekushisa kwakadzikama panguva yekushanda kwebhatiri, nokudaro kunowedzera kuchengeteka uye kuwedzera hupenyu hwebhatiri. - Yakanaka Shock Absorption Performance:
Kana bhatiri paki rasangana kana kudhumhana, melamine furo inobata maitiro, kudzivirira chimiro chemukati chebhatiri. Kubata kwayo kwakanakisa kwekuvhundutsa kunobva muhuro hwekunyungudika kwehuro uye kugona kusimudza. Yekuyedza data inoratidza kuti melamine foam yekumanikidza simba inogona kusvika 100-150 kPa, kuderedza kukuvadzwa kunokonzerwa nekudengenyeka panguva yekutakura bhatiri, kusangana, uye kushandiswa. - Kuramba Kwemoto:
Melamine foam yakakwirira kupisa moto inoderedza zvakanyanya njodzi yemoto mumabhatiri mapaketi. Zvayo oxygen index (OI) inowanzobva pa28-30, zvichiratidza zvinhu zvakanaka zvekudzima. Chiyero chayo chekupikisa moto chinosangana neUL 94 V-0 yakajairwa, zvichireva kuti furo harizobatidza kana kukonzera moto kunyangwe pasi pekupisa kwakanyanya, kuwedzera kuchengetedzwa kwebhatiri. - Lightweight uye Kushamwaridzana Nezvakatipoteredza:
Melamine foam ikareruka, ine density inowanzobva kubva 6-50 kg/m³. Kana ichienzaniswa neyechinyakare yekupisa manejimendi zvinhu, inoderedza zvakanyanya huremu hwebhatiri paki, ichibatsira mota dzemagetsi kuwana zvirinani simba rekushandisa. Pamusoro pezvo, melamine foam inosangana nezvakawanda zvakatipoteredza zviyero uye inogona kushandiswazve, zvichiita kuti ive chinhu chakanakira mabhatiri mapaketi.
Nemabhenefiti aya akakosha, melamine foam inoita basa rinowedzera kukosha mukudzora kupisa kwebhatiri, kunyanya mukuvandudza kuchengetedzwa kwebhatiri remotokari yemagetsi, kuwedzera hupenyu hwebhatiri, uye kuwedzera simba remagetsi.
mhedziso:
Sezvo musika wemotokari dzemagetsi uchikura nekukurumidza, kuchengetedzeka kwebhatiri kwave kutarisisa pasirese. GB38031-2025, seyeChina yazvino bhatiri chengetedzo chiyero, haingogadziri zvakaomarara zvinodiwa mudzimba asi zvakare inopa chirevo chekuwedzera kusimudzira kwemazinga epasi rose. Kuburikidza nekuenzanisa nezviyero zveEU, US, uye Japan, tinogona kuona zvinonetsa uye nekusimbisa kwakasiyana munyika dzese mumunda wekuchengetedza bhatiri. Melamine foam, sechinhu chitsva, inoita basa rakakosha mukusimudzira kuchengetedzwa kwebhatiri paki, manejimendi ekupisa, uye kuramba moto, uye ichave chikamu chakakosha chekugadzirwa kwebhatiri remotokari mune ramangwana.
Kuti uwane rumwe ruzivo nezve GB38031-2025 zviyero kana mashandisirwo emelamine foam mumabhatiri, ndapota shanyira anoenderana akajairwa zvinongedzo kana kutibata nesu.
