Eminyakeni yamuva nje, ngokukhula okuqhubekayo kwenani lezimoto ezintsha zamandla, imvamisa yezingozi zomlilo zezimoto ezintsha zamandla nayo ikhule unyaka nonyaka, okusongela kakhulu ukuphepha kwezimpilo zabashayeli kanye nempahla yabo. Izimbangela zomlilo ezimotweni ezintsha zamandla zibangelwa yizici eziningi. Phakathi kwazo, ukushaja ngokweqile, ukukhipha, ukushayisana, ukuhamba kwamanzi kanye nezinye izimo ezinzima zebhethri lamandla kanye nezinkinga zenqubo yokukhiqiza kungabangela ukuqhuma kwebhethri ngokushisa futhi kubangele ukuthi imoto entsha yamandla ibambe umlilo noma iqhume ngisho nokuqhuma.
Uma kwenzeka ingozi yomlilo emotweni entsha yamandla, yize izinga lokushisa lomlilo lebhethri le-lithium-ion liphansi uma lisha, lapho umlilo webhethri ucinywa ngokuphelele, izinga lokushisa lebhethri aliweli ezingeni eliphephile ngokushesha, futhi kukhiqizwa inani elikhulu legesi enobuthi. Ngisho noma licwiliswe emanzini, kuzothatha isikhathi eside ukuthi izinga lokushisa lalo lehle liye ezingeni eliphephile, futhi ibhethri nalo livame ukusha kabusha, okusabalala ngokushesha okukhulu.
Uma imoto entsha yamandla ibamba umlilo, i-voltage kanye nokushisa kwenhliziyo yebhethri enephutha kuzokhuphuka ngokushesha futhi isikhathi sokudlulisa ukushisa sizoba sifushane kakhulu, okubangela indawo enkulu yokushisa kwenhliziyo yebhethri esikhathini esifushane. Uma izinguquko zepharamitha yesici seseli yebhethri elilodwa elinephutha zingabanjwa ngokunembile futhi umshayeli angaxwayiswa, ukwenzeka kwezingozi kuzoncishiswa.
Uma imoto kagesi ihlangana nokushayisana komshini, ibhethri liyacindezelwa bese lishayisana, noma imoto kagesi isha, igobolondo lephakethe lebhethri libalulekile ekuvikelweni komshini kwephakethe lebhethri. Thuthukisa ukusebenza okuvimbela umlilo kwebhokisi. Uma kwenzeka ukushiswa kwebhethri, ibhokisi elivimbela umlilo kakhulu linomsebenzi wokuvimbela ukusabalala komlilo. Ukuthuthukisa ukusebenza kokuvala kwebhethri kunomthelela omkhulu ekuvimbeleni ukuvuza kwegesi kanye nokusabalala komlilo lapho iphakethe lebhethri licwiliswa emanzini noma ukushiswa kwebhethri. Isembozo esivimbela umlilo sisetshenziswa ebusweni begobolondo ukuthuthukisa ukumelana komlilo kwegobolondo lephakethe lebhethri.
I-flame-retardant i-melamine foam can be installed between the module, battery cell and battery pack shell. Melamine foam may be assessed as one thermal or acoustic layer in a battery pack, but its ability to delay heat propagation or influence thermal-runaway behaviour must be established in the specific installed assembly. Foam alone cannot be relied on to stop cell-to-cell thermal runaway or fire spread. The structure of the battery box can also use high-strength materials, use reinforcing ribs or set up buffer devices, etc., and set up buffer structures to buffer and absorb part of the force of collisions, protect the battery pack from damage, and reduce the risk of short circuits caused by mechanical collisions.
At present, the fireproof materials of new energy vehicle battery packs are mainly laid with fireproof felt materials, such as insulation blankets, mica boards, ultra-fine glass wool, high silica cotton felts, etc. Although fireproof felt can effectively isolate heat diffusion, control the direction of fire, and delay the heat diffusion time of the battery, adding fireproof felt also has problems such as increased mass, which is not conducive to the development of lightweight vehicles, poor heat dissipation performance, and limitations in the design and construction process. Therefore, according to the market demand for safety and lightweight of power battery packs, melamine foam is one candidate for selected nonstructural thermal and acoustic functions in battery assemblies, subject to cell-level and system-level safety qualification.
I-SINOYQX ihlinzeka ngezinto ezisebenzayo nezisombululo zokwenziwa kwezimoto, ikakhulukazi ngezidingo ezisezingeni eliphakeme zamabhethri amasha e-Thermal Insulation, I-Flame Retardant, kanye Nokugcinwa Kokushisa, ngokusekelwe emandleni akhona okuklama nokukhiqiza, ngokuqamba okusha okuqhubekayo nocwaningo kanye nentuthuko ngohlobo lwayo lwe-YQX-C6 olusuka ekwelashweni okukhethekile kwegwebu le-melamine.
Izakhiwo Zezinto Ezintsha Zephakethe Lebhethri Lamandla e-SINOYQX
- Flame behaviour: confirm UL94 and other applicable results using the specific material grade and test report; these do not establish battery-pack fire safety
- omuhle ukufakwa okushisayo (i-thermal conductivity, 0.035 W/ (m*K))
- Electrical insulation: a dielectric rating must be demonstrated through applicable dielectric-strength, withstand-voltage, creepage and assembly-level tests; no voltage rating is implied by foam resistivity alone
- Service temperature: evaluate the exact foam grade, exposure duration and complete assembly; published material temperature limits are not an automatic battery-system rating
- Ukuguquguquka (okuncane kakhulu kungafinyelela ku-0.3mm)
- Isisindo Esilula (8~51KG/M3)
- Substance, emissions and acoustic performance: verify with grade-specific documentation. Combustion products must not be described as non-toxic; chemical resistance, antimicrobial properties and NRC depend on testing, grade and installed thickness
- Ukwakheka kwesibili kokucubungula (kulula ukukusika, kunganamatheliswa noma kufakwe i-laminate, njll.)
