M'zaka zaposachedwapa, ndi kukula kosalekeza kwa magalimoto atsopano amphamvu, mafupipafupi a ngozi zamoto zamoto zamphamvu zatsopano zawonjezeka chaka ndi chaka, zomwe zikuika pangozi moyo wa oyendetsa galimoto ndi katundu wawo. Zomwe zimayambitsa moto m'magalimoto atsopano amphamvu zimayambitsidwa ndi zinthu zambiri. Pakati pawo, kuchulukirachulukira, kutulutsa, kugundana, kusefukira kwamadzi ndi zovuta zina za batri yamagetsi ndi zovuta zopangira kupanga zingayambitse kutha kwa batri ndikupangitsa kuti galimoto yamagetsi yatsopano igwire moto kapena kuphulika.
Pankhani ya ngozi yamoto mu galimoto yatsopano yamagetsi, ngakhale kutentha kwa moto wa batri ya lithiamu-ion kumakhala kochepa kwambiri pamene ikuyaka, pamene moto wa batri uzimitsidwa, kutentha kwa batri sikutsika mofulumira, ndipo mpweya wochuluka wa poizoni umapangidwa. Ngakhale atamizidwa m’madzi, zimatenga nthawi yaitali kuti kutentha kwake kugwere pamalo otetezeka, ndipo batireyo imakondanso kuyatsanso, yomwe imafalikira mofulumira kwambiri.
Galimoto yatsopano ikagwira moto, mphamvu yamagetsi ndi kutentha kwa batri yolakwika idzakwera mofulumira ndipo nthawi yotumizira kutentha idzakhala yaifupi kwambiri, zomwe zimapangitsa kuti pakhale kutentha kwakukulu kwapakati pa batri mu nthawi yochepa. Ngati mawonekedwe akusintha kwa batire imodzi yolakwika akhoza kugwidwa molondola ndipo woyendetsa akhoza kuchenjezedwa, zochitika za ngozi zidzachepetsedwa.
Galimoto yamagetsi ikakumana ndi kugunda kwamakina, batire imafinyidwa ndikuwombana, kapena galimoto yamagetsi ikayaka moto, chipolopolo cha batri ndichofunikira pakutetezedwa kwamakina a paketi ya batri. Limbikitsani ntchito yoletsa moto ya choyikapo. Pamene kutentha kwa batri kuthawa, choyikapo chotchinga moto chimakhala ndi ntchito yoletsa kufalikira kwa moto. Kupititsa patsogolo kusindikiza kwa batire kumakhudza kwambiri kupewa kutayikira kwa gasi ndi kuyaka kuyaka pamene batire paketi yamizidwa m'madzi kapena kuthawa kwamafuta. Chophimba choletsa moto chimagwiritsidwa ntchito pamwamba pa chipolopolo kuti chiwongolere kukana kwa lawi la chipolopolo cha batri.
Zoletsa moto melamine thovu 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.
SINOYQX imapereka zida zaukadaulo ndi mayankho opangira magalimoto, makamaka pazofunikira zapamwamba zamabatire amagetsi atsopano a Thermal Insulation, Flame Retardant, ndi Heat Preservation, kutengera luso lomwe lilipo komanso kupanga, kudzera muukadaulo wopitilira komanso kafukufuku ndi chitukuko ndi mtundu wake wa YQX-C6 kuchokera kumankhwala apadera a thovu a melamine.
SINOYQX New Energy Battery Pack Material Properties
- Flame behaviour: confirm UL94 and other applicable results using the specific material grade and test report; these do not establish battery-pack fire safety
- chabwino mafuta kutchingira (madulidwe amafuta, 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
- kusinthasintha (thinnest akhoza kufika 0.3mm)
- Opepuka (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
- Secondary processing formability (osavuta kudula, akhoza kubwerera glued kapena laminated, etc.)
