I nga tau tata nei, na te tipu haere tonu o te maha o nga waka hiko hou, kua piki ake ano te maha o nga aitua ahi waka hiko hou i ia tau, i ia tau, ka tino whakararu i te oranga o nga kaitaraiwa me nga rawa. Ko nga take o te ahi i roto i nga waka hiko hou he maha nga take. I roto i era, ko te nui o te utu, te tangohanga, te tukinga, te wai wai me etahi atu ahuatanga kino o te pākahiko hiko me nga raru o te mahi whakangao ka paheke te waiariki o te pākahiko, ka mau te waka hiko hou ki te ahi, ka pahū ranei.
Mena he aitua te ahi i roto i tetahi waka hiko hou, ahakoa he iti te mura o te ahi o te pākahiko lithium-ion i te wa e wera ana, ka mutu te ahi o te pākahiko, karekau te pāmahana o te pākahiko e heke tere ki te taumata haumaru, ka puta te nui o te hau paitini. Ahakoa ka rumakina ki roto i te wai, ka roa te wa ka heke iho te pāmahana ki te taumata haumaru, a ka kaha hoki te puhipuhi ki te mura ano, ka tere te horapa.
Ina ka mau te waka hiko hou, ka tere te piki o te ngaohiko me te mahana o te matua o te pākahiko he, ka poto rawa te wa whakawhiti wera, ka puta he waahi nui o te waiariki o te matua pākahiko i roto i te wa poto. Mena ka huri te tawhā ahuatanga o te pūtau pākahiko kotahi he he ka taea te hopu tika, ka taea te whakatupato i te taraiwa, ka iti haere nga aitua.
Ka pa mai tetahi waka hiko ki te tukinga miihini, ka kohia te pākahiko ka tukituki, ka mau ranei te waka hiko, he mea nui te anga o te pākahiko ki te whakamarumaru miihini o te kete pākahiko. Whakanuia te mahi mura-muri o te casing. I te wa e rere ana te waiariki o te pākahiko, ko te putunga mura-muri teitei te mahi hei aukati i te horapa o te ahi. Ko te whakapai ake i te mahi hiri o te pākahiko ka whai paanga nui ki te aukati i te rerenga hau me te whakamararatanga ngingiha ina rukuhia te kete pākahiko ki te wai, ki te waiariki ranei. Ka whakamahia te paninga mura-muri ki runga i te mata o te anga hei whakarei ake i te parenga mura o te anga kete pākahiko.
Te mura o te ahi pahuka melamine 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.
Ka whakarato a SINOYQX i nga rauemi ngaio me nga otinga mo te hanga motuka, ina koa mo nga whakaritenga paerewa teitei o nga pākahiko hiko hou mo te Wehenga Weariki, Te Mura Te Mura, me te Tiaki Wera, i runga i te hoahoa o naianei me nga kaha whakaputa, na roto i nga mahi hou me te rangahau me te whanaketanga me tana momo YQX-C6 mai i te maimoatanga pahuka melamine motuhake.
SINOYQX New Energy Pūhiko Pūhiko Āhuatanga Rawa
- Flame behaviour: confirm UL94 and other applicable results using the specific material grade and test report; these do not establish battery-pack fire safety
- pai wehenga waiariki (te kawe werawera, 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
- Te ngawari (ka tae ki te 0.3mm te mea angiangi)
- Kōmāmā(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
- Ko te ahua o te tukatuka tuarua (he ngawari ki te tapahi, ka taea te hoki ki te whakapiri, ki te raima ranei, me etahi atu)
