Pakadali pano, kuipitsa dziko lonse lapansi kukuchulukirachulukira tsiku ndi tsiku. Utsi wochokera m'magalimoto akale otulutsa mafuta wawonjezera kuipitsa mpweya komanso kuchuluka kwa mpweya woipa wochokera m'dziko lonse. Kusunga mphamvu ndi kuchepetsa utsi kwakhala nkhani yofunika kwambiri kwa anthu apadziko lonse lapansi (HVCHMagalimoto atsopano amphamvu ali ndi gawo lalikulu pamsika wamagalimoto chifukwa cha mphamvu zawo zamagetsi zogwira ntchito bwino, zoyera komanso zosadetsa. Monga gwero lalikulu la mphamvu zamagalimoto amagetsi oyera, mabatire a lithiamu-ion amagwiritsidwa ntchito kwambiri chifukwa cha mphamvu zawo zapadera komanso moyo wautali.
Lithium-ion imapanga kutentha kwambiri ikagwira ntchito komanso ikatulutsa, ndipo kutentha kumeneku kudzakhudza kwambiri magwiridwe antchito ndi moyo wa batri ya lithiamu-ion. Kutentha kwa batri ya lithiamu ndi 0 ~ 50 ℃, ndipo kutentha kwabwino kwambiri kogwira ntchito ndi 20 ~ 40 ℃. Kuchuluka kwa kutentha kwa batri yopitilira 50 ℃ kudzakhudza mwachindunji moyo wa batri, ndipo kutentha kwa batri kukapitirira 80 ℃, batriyo ikhoza kuphulika.
Poganizira kwambiri za kasamalidwe ka kutentha kwa mabatire, pepalali likufotokoza mwachidule za ukadaulo woziziritsa ndi kutenthetsa wa mabatire a lithiamu-ion omwe akugwira ntchito pophatikiza njira ndi ukadaulo wosiyanasiyana woziziritsa kutentha kunyumba ndi kunja. Poganizira kwambiri za kuziziritsa mpweya, kuziziritsa madzi, ndi kuziziritsa kusintha kwa gawo, kupita patsogolo kwa ukadaulo woziziritsa batire komanso mavuto omwe alipo pakali pano pakukula kwaukadaulo akukonzedwa, ndipo mitu yofufuza yamtsogolo yokhudza kasamalidwe ka kutentha kwa batire ikuperekedwa.
Kuziziritsa mpweya
Kuziziritsa mpweya ndiko kusunga batri pamalo ogwirira ntchito ndikusinthitsa kutentha kudzera mumlengalenga, makamaka kuphatikiza kuziziritsa mpweya mokakamizidwa (Chotenthetsera mpweya cha PTC) ndi mphepo yachilengedwe. Ubwino wa kuziziritsa mpweya ndi mtengo wotsika, kusinthasintha kwakukulu, komanso chitetezo champhamvu. Komabe, pa mabatire a lithiamu-ion, kuziziritsa mpweya kumakhala ndi mphamvu yochepa yosamutsa kutentha ndipo kumakhala ndi kufalikira kosagwirizana kwa kutentha kwa paketi ya batire, kutanthauza kuti kutentha kofanana. Kuziziritsa mpweya kumakhala ndi zoletsa zina chifukwa cha mphamvu yake yochepa yotenthetsera, kotero kumafunika kukhala ndi njira zina zoziziritsira nthawi imodzi. Mphamvu yozizira ya kuziziritsa mpweya imagwirizana kwambiri ndi kapangidwe ka batire ndi malo olumikizirana pakati pa njira yoyendera mpweya ndi batire. Kapangidwe ka dongosolo lowongolera kutentha kwa batire yoziziritsidwa mpweya wofanana kumawongolera magwiridwe antchito ozizira a dongosololi posintha kufalikira kwa malo a batire a paketi ya batire mu dongosolo loziziritsidwa mpweya wofanana.
kuziziritsa kwamadzimadzi
Mphamvu ya chiwerengero cha othamanga ndi liwiro la kuyenda kwa madzi pa zotsatira zoziziritsira
Kuziziritsa kwamadzimadzi (Chotenthetsera choziziritsira cha PTC() imagwiritsidwa ntchito kwambiri pochotsa kutentha kwa mabatire agalimoto chifukwa cha mphamvu yake yabwino yochotsa kutentha komanso kuthekera kosunga kutentha kofanana kwa batire. Poyerekeza ndi kuziziritsa mpweya, kuziziritsa madzi kumakhala ndi mphamvu yabwino yosamutsa kutentha. Kuziziritsa madzi kumakwaniritsa kutayitsa kutentha mwa kutsitsa choziziritsira m'njira zozungulira batire kapena kuviika batire m'choziziritsira kuti chichotse kutentha. Kuziziritsa madzi kuli ndi ubwino wambiri pankhani ya kuziziritsa bwino komanso kugwiritsa ntchito mphamvu, ndipo kwakhala njira yayikulu yoyendetsera kutentha kwa batire. Pakadali pano, ukadaulo woziziritsira madzi umagwiritsidwa ntchito pamsika monga Audi A3 ndi Tesla Model S. Pali zinthu zambiri zomwe zimakhudza zotsatira za kuziziritsa madzi, kuphatikizapo momwe chubu choziziritsira madzi chimakhudzira mawonekedwe, zinthu, choziziritsira madzi, kuchuluka kwa madzi ndi kutsika kwa kuthamanga kwa mpweya pamalo otulukira. Potengera chiwerengero cha othamanga ndi chiŵerengero cha kutalika ndi m'mimba mwake cha othamanga ngati zosinthika, mphamvu ya magawo awa pa mphamvu yozizira ya dongosolo pamlingo wotulutsa wa 2 C idaphunziridwa posintha kapangidwe ka malo olowera othamanga. Pamene chiŵerengero cha kutalika chikukwera, kutentha kwakukulu kwa paketi ya batire ya lithiamu-ion kumachepa, koma chiwerengero cha othamanga chimawonjezeka kufika pamlingo winawake, ndipo kutsika kwa kutentha kwa batire kumachepanso.
