Vim nws lub siab ntom ntom ntom thiab loj muaj peev xwm, lub zog teeb tsa cia kom nws muaj kev tiv thaiv kev nyab xeeb dua li tsev neeg lossis me me-teev lub zog cia khoom. Kev lag luam tam sim no tau tsim tsa peb-seem kev tiv thaiv kev tiv thaiv kev nyab xeeb, thiab kev saib xyuas cov ntaub ntawv kev saib xyuas loj heev rau cov ntawv thov hluav taws xob loj.
1 Intrinsic kev nyab xeeb kev tsim qauv ntawm cov roj teeb hlwb thiab cov qauv
Kev xaiv cell yog thawj qhov chaw kuaj xyuas kev tiv thaiv kev nyab xeeb. Lithium iron phosphate roj teeb tau dhau los ua cov thawv ntim hluav taws xob cia rau qhov kub thiab txias (li 500 degree) piv rau cov roj ntsha lithium (txog 200 degree). Tom qab tau txais Lithium Iron phosium phosphate roj teeb rau hauv 100MWH Project, qhov kev pheej hmoo ntawm Thermal khiav tawm tau raug txo los ntawm 70%. Hauv cov txheej txheem ntau lawm ntawm cov roj teeb hauv lub cev, tsis yog kev rhuav tshem cov kev phom sij me me ntawm cov duab micro me me thiab ultrasound, thiab tus nqi tsis zoo hauv qab 0.001%.
Tus qauv kev ruaj ntseg ntawm cov qib qib qis hauv cov kab sib kis. Txhua lub roj teeb mchule yog tsim los ua hluav taws kub. Lub cev Cabin yog ua los ntawm Ceramic Fiber Board (hluav taws kub ua haujlwm kub 1200 degree), thiab cov modures muaj cov airgel (thermal conductivity 0.018w / (maple. Txawm hais tias muaj kub ntawm ib qho module yog tawm ntawm kev tswj, qhov kub siab tuaj yeem tswj tau thaj chaw mus rau ntau dua 30 feeb. Lub "fuse hom" module tsim ntawm ib qho chaw tsim khoom txiav txiav qhov kev sib txuas hluav taws xob nrog 80 degree, tiv thaiv cov saw sib txawv.
2 ib puag ncig tswj thiab qhia ntxov ntxov
Ua kom meej cov kev tswj hwm qhov kub thiab txias kev tswj hwm kev ua rau ntawm thermal khiav khiav. Lub thawv ntim cov tshuab tsim hluav taws xob kub ntawm "cov kua txias rau lub chaw txias rau hauv lub tsev huab cua huab cua (kev txuag 40% lub zog piv rau ib qho cua txias. Thaum qhov ntsuas kub tsis zoo (tshaj 35 degree) tau kuaj pom nyob hauv thaj chaw ntawd, tswj qhov sib txawv txias hauv 5 degree, thiab zam kev kub ntxhov hauv ib cheeb tsam.
Zov ntau lub sensor network rau cov lus ceeb toom ntxov. Txhua pawg roj teeb yog nruab nrog kub (qhov tseeb ± 0.5 degree), voltage, thiab roj (hf) zaus, nrog cov ntaub ntawv ntsuas ntawm 10Hz. Ai cov algorithms yog siv los txheeb xyuas thermal runaway prefawors (xws li nce zuj zus hauv Co concentration thiab voltage dauv). Cov lus ceeb toom ntawm qee qhov chaw nres tsheb hluav taws xob ntes tau cov teeb meem ntawm cov roj teeb txawv, thiab ua ntej lub sijhawm ceeb toom ntawm kev saib xyuas kub.
3 Innovation hauv Kev Tshawb Fawb Thaum Muaj Xwm Txheej Ceev thiab Kev Nyab Xeeb Kev Nyab Xeeb
Kev teb hluav taws xob hluav taws kub sai khawm tua hluav taws tuaj yeem muaj kev kis hluav taws. Cov thawv ntim tau nruab nrog "roj-kua sib txuas" hluav taws xob tua hluav taws xob, uas tso tawm heptafluoropane (ntxuav cov pa taws rau hauv lub txee rau hauv qab 12% hauv 30 feeb; Yog tias cov hluav taws kub kis, ua kom cov dej-ua haujlwm tua hluav taws (txau cov kab tsuag 6L / Minin ²) kom txias lub roj teeb kub kom qis dua 100 degree. Ib cov ntaub ntawv xeem qhia tau tias lub system tuaj yeem tua hluav taws qhib cov nplaim hluav taws ntawm 3 feeb, nrog kev ua tiav ntawm 100%.
Cov pa taws sib xyaw thiab kev siv cais tawm los txo cov kev puas tsuaj thib ob. Tawg cov pa hluav taws tso pa hluav taws xob ua pa hluav taws xob (nrog rau kev qhib siab ntawm 0.1mpa) tau nruab rau sab saum toj ntawm lub thawv. Cov pa luam yeeb kub (kub tshaj 800 degree) tsim los ntawm thermal khiav tawm los ntawm kev tso tawm tsis pub dhau 10 feeb kom tsis txhob tawg; Kev siv hluav taws xob 3-metre-me me yog teeb tsa ntawm cov thawv uas nyob ib sab, nruab nrog hluav taws kub dov kaw. Thaum ib lub thawv ib lub thawv raug hluav taws, nws tuaj yeem raug cais sai sai los tiv thaiv kev kis hluav taws. Qhov hluav taws xob laum ntawm qee qhov chaw nres tsheb hluav taws xob tau ua pov thawj tias cov qauv hluav taws xob no tuaj yeem tswj cov hluav taws kub thiab txo qhov kev pheej hmoo ntawm cov saw hlau los ntawm 90%.
Kev tiv thaiv kev nyab xeeb ntawm cov thawv zog hluav taws xob cia yog kev sib xyaw ua ke ntawm kev tsim kho kev ua haujlwm thiab cov qauv tshwj xeeb. Nrog kev txhim kho cov qauv xws li ul9540A thiab GB / lub zog muaj hluav taws xob rau kev nyab xeeb thiab ruaj khov ua haujlwm ntawm cov tshuab hluav taws xob tshiab.
