Kwiminyaka yakutshanje, ngokukhula okuthe gqolo kwenani lezithuthi zamandla amatsha, ukubaleka kweengozi zomlilo zeenqwelo zamandla amatsha nako kuye kwanda unyaka nonyaka, kubeka emngciphekweni ukhuseleko lobomi babaqhubi kunye nempahla. Izizathu zomlilo kwizithuthi zamandla amatsha zibangelwa zizinto ezininzi. Phakathi kwazo, ukutshaja, ukukhutshwa, ukungqubana, ukuntywila kwamanzi kunye nezinye iimeko ezinzima zebhetri yamandla kunye neengxaki zenkqubo yokuvelisa kunokubangela ukubaleka kwebhetri kwaye kubangele ukuba isithuthi samandla esitsha sibambe umlilo okanye siqhume.
Kwimeko yengozi yomlilo kwimoto entsha yamandla, nangona ukushisa kwelangatye kwebhetri ye-lithium-ion kuncinci xa kutshisa, xa umlilo webhetri ucinywa ngokupheleleyo, ukushisa kwebhetri akuwehli kwinqanaba elikhuselekileyo ngokukhawuleza, kunye nenani elikhulu legesi enetyhefu iveliswa. Nokuba intywiliselwe emanzini, kuya kuthatha ixesha elide ukuba iqondo lobushushu lihle liye kumgangatho okhuselekileyo, kwaye ibhetri iyakwazi ukuvutha kwakhona, esasazeka ngokukhawuleza.
Xa isithuthi samandla esitsha sibamba umlilo, i-voltage kunye nobushushu be-core yebhetri ephosakeleyo iya kunyuka ngokukhawuleza kwaye ixesha lokudlulisa ubushushu liya kuba lifutshane kakhulu, kubangele indawo enkulu yokubaleka kwe-thermal ye-core core ngexesha elifutshane. Ukuba utshintsho lweparameter yeempawu zeseli yebhetri enye enempazamo inokubanjwa ngokuchanekileyo kwaye umqhubi angalumkiswa, ukwenzeka kweengozi kuya kuncitshiswa.
Xa isithuthi sombane sidibana nongquzulwano ngoomatshini, ibhetri iyacinezelwa kwaye ingqubane, okanye isithuthi sombane sibambe umlilo, iqokobhe lebettery pack ibalulekile kukhuseleko lomatshini lwepakethi yebhetri. Ukwandisa ukusebenza kwe-casing-retardant flame. Xa ibhetri ibaleka i-thermal, i-casing ephezulu ye-flame-retardant inomsebenzi wokuthintela ukusasazeka komlilo. Ukuphucula ukusebenza kokutywinwa kwebhetri kunempembelelo enkulu ekuthinteleni ukuvuza kwegesi kunye nokusasazwa kokutsha xa ipakethi yebhetri intywiliselwa emanzini okanye ekubalekeni kwe-thermal. Utyatyazo olubuthisa amadangatya lusetyenziswa kumphezulu weqokobhe ukomeleza ukuxhathisa kwedangatye kwiqokobhe lepakethi yebhetri.
I-flame-retardant melamine amagwebu 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 ibonelela ngezinto zobuchwephesha kunye nezisombululo zokwenziwa kweemoto, ngakumbi kwiimfuno ezikumgangatho ophezulu weebhetri zamandla amatsha kwi-Thermal Insulation, i-Flame Retardant, kunye nokuGcinwa koBushushu, ngokusekelwe kuyilo olukhoyo kunye namandla okuvelisa, ngokuqhubekayo ngokutsha kunye nophando kunye nophuhliso kunye nohlobo lwayo lwe-YQX-C6 oluvela kunyango olukhethekileyo lwe-melamine foam.
I-SINOYQX iiMpakethi zeMathiriyeli yeBetri yaMandla amatsha
- Flame behaviour: confirm UL94 and other applicable results using the specific material grade and test report; these do not establish battery-pack fire safety
- Zintle ukufakelwa kobushushu (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
- Ukuba bhetyebhetye (eyona i-thinnest inokufikelela kwi-0.3mm)
- Ikhaphukhaphu(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
- Ukubunjwa kokulungiswa kwesibini (kulula ukusika, kunokubuyisela iglu okanye i-laminated, njl.)
