Bitewe n’ubwiyongere bw’ibicuruzwa bishya bikoresha ingufu, impanuka z’inkongi z’umuriro ku binyabiziga bishya bikoresha ingufu nazo zibaho rimwe na rimwe. Imiterere ya sisitemu yo gucunga ubushyuhe ni ikibazo gikomeye kibangamira iterambere ry’ibinyabiziga bishya bikoresha ingufu. Gutegura sisitemu yo gucunga ubushyuhe ihamye kandi ikora neza ni ingenzi cyane mu kunoza umutekano w’ibinyabiziga bishya bikoresha ingufu.
Uburyo bwo gushyushya bwa bateri ya Li-ion ni bwo shingiro ry’imicungire y’ubushyuhe bwa bateri ya Li-ion. Muri byo, uburyo bwo gushyushya bwa bateri ya Li-ion butuma ubushyuhe bukwirakwira ndetse n’uburyo bwo gushyushya bwa bateri ya Li-ion butuma ubushyuhe bukwirakwira ni ibintu bibiri by’ingenzi mu buryo bwo gushyushya bwa bateri ya Li-ion. Mu bushakashatsi busanzwe ku bijyanye no gushyushya bwa bateri, bateri ya Li-ion ifatwa nk’ifite ubushobozi bwo gushyushya bwa anisotropic. Kubwibyo, ni ingenzi cyane kwiga ingaruka z’ahantu hatandukanye ho gushyushya n’ubuso bwo gushyushya ku gushonga k’ubushyuhe no gutwara ubushyuhe bwa bateri ya Li-ion kugira ngo hakorwe uburyo bwiza kandi bwizewe bwo gucunga ubushyuhe bwa bateri ya Li-ion.
Iselile ya bateri ya lithium fosfeti ifite ubushobozi bwa 50 A·ah niyo yakoreshejwe nk'ubushakashatsi, kandi imiterere yayo yo kohereza ubushyuhe yarasesenguwe mu buryo burambuye, maze igitekerezo gishya cyo gushushanya imicungire y'ubushyuhe cyatanzwe. Imiterere y'iselile igaragara ku Ishusho ya 1, kandi ibipimo by'ingano byihariye bigaragazwa ku Imbonerahamwe ya 1. Imiterere ya bateri ya Li-ion muri rusange ikubiyemo electrode nziza, electrode mbi, electrolyte, separator, electrode nziza, electrode mbi, terminal yo hagati, ibikoresho bikingira ubushyuhe, valve y'umutekano, coefficient nziza y'ubushyuhe (PTC)(Igishyushya gikonjesha cya PTC/Igishyushya cy'umwuka cya PTC) thermistor n'agasanduku ka bateri. Agace gatandukanya gashyirwa hagati y'ibice bya positive na negative pole, maze igice cy'imbere cya bateri kigakorwa hifashishijwe winding cyangwa itsinda rya pole rigakorwa hifashishijwe lamination. Oroshya imiterere y'uturemangingo twinshi mu bikoresho by'uturemangingo bifite ingano imwe, kandi ukore uburyo bungana ku bipimo bya thermophysical by'uturemangingo, nk'uko bigaragara ku Ishusho ya 2. Ibikoresho by'uturemangingo twa bateri bifatwa nk'igice cya cuboid gifite imiterere ya anisotropic thermal conductivity, kandi thermal conductivity (λz) igororotse ku cyerekezo cyo gukusanya ishyirwaho ko ari ntoya kuruta thermal conductivity (λ x, λy) ijyanye n'icyerekezo cyo gukusanya.
(1) Ubushobozi bwo gukwirakwiza ubushyuhe bwa gahunda yo gucunga ubushyuhe ya bateri ya lithiamu-ion buzagirwaho ingaruka n'ibipimo bine: uburyo ubushyuhe bufata bugororotse bugana ku buso bukwirakwiza ubushyuhe, intera iri hagati y'aho ubushyuhe buturuka n'aho butwikira ubushyuhe buturuka, ingano y'ubuso bukwirakwiza ubushyuhe bwa gahunda yo gucunga ubushyuhe, n'itandukaniro ry'ubushyuhe hagati y'ubuso bukwirakwiza ubushyuhe n'ibidukikije bibukikije.
(2) Mu guhitamo ubuso bwo gukwirakwiza ubushyuhe mu rwego rwo gucunga ubushyuhe bwa bateri za lithiamu-iyoni, gahunda yo kohereza ubushyuhe ku ruhande rw'ikintu cyatoranijwe mu bushakashatsi ni nziza kuruta gahunda yo kohereza ubushyuhe ku buso bwo hasi, ariko kuri bateri kare zitandukanye, ni ngombwa kubara ubushobozi bwo gukwirakwiza ubushyuhe ku buso butandukanye bwo gukwirakwiza ubushyuhe kugira ngo hamenyekane ahantu heza ho gukonjesha.
(3) Iyi formula ikoreshwa mu kubara no gusuzuma ubushobozi bwo gukwirakwiza ubushyuhe, kandi igereranya ry'imibare rikoreshwa mu kwemeza ko ibisubizo bihuye neza, bigaragaza ko uburyo bwo kubara bufite akamaro kandi bushobora gukoreshwa nk'icyitegererezo mu gushushanya uburyo bwo gucunga ubushyuhe bw'uturemangingo kare.BTMS)
