Ni igiki co gukonjesha?
Ikibazo ca James Wong, Fremont, muri California.
Nkora ku ruganda rwa kera rwa GM{0}}Toyota NUMMI hano kandi twumvise gusa ko tuzokora imodoka y’umuyagankuba umusi umwe. Abantu baguma bavuga ivy’ugukonjesha bateri. Inkuru nyayo ni iyihe?
Ishura Richard Flagan, umwigisha w’ubuhinga bw’imiti n’ubuhinga bw’ibidukikije, muri Caltech.
(Ndakora ibikorwa vy’ubuhinga bwa aerosol cane cane, ariko narakwegerewe mu migambi ibiri y’amabateri n’amashirahamwe y’imodoka muri iyi misi iheze.)
Igipande ca litiyumu - ipaki ikora ubushuhe butangaje iyo uyisunikiye. Igikoresho ca 60 kWh ku 3C charge ishobora gutera ubushuhe bwa 15–20 kW. Ico ni ikibanza gitoyi co gushusha mu kirere kigendagenda hasi mu modoka. Uyirekere wenyene kandi utugingo ngengabuzima two hagati twateye 60℃mu gihe ukiriko uragerageza gushika ku 80 %. Ubuzima buragabanuka vuba cane hejuru ya degre 45 , rero utegerezwa gukuraho ubushuhe.
Ivyinshi mu bipapuro ubu bikoresha amasahani y’imbeho y’aluminium nk’iminota 4–6 n’umurongo w’imbere. Uca unyerera isahani imwe hagati y’ibice bibiri vyose canke munsi y’umurongo wose w’imifuko. Ico gipande cuzuye igice c’ubushuhe bukeyi ku mfuruka z’ingingo. Amasahani ya GM’s Ultium ni nk’ayo. Tesla yakoresheje umurongo w’uruzitiro ruri munsi ya 18650 na 2170s mu zigzag- isa n’iyitwa spaghetti, ikora neza, ariko ni ububabare bwo gukoranya. Ico gipfukisho gishasha ca 4680 muri Texas caragiye ku rubavu rwagutse rwapfutse aho gushika ku nzira y’uruzitiro. Biroroshe gushaka.
Coolant hafi y’igihe cose amazi 50/50 -glycol n’ibibuza bisanzwe. Imodoka zimwe zimwe z’amarushanwa zigenda zigenda zigenda zigenda neza canke mbere n’amavuta ya silikoni, ariko nta n’umwe yohereza abakiriya. Flow akenshi ni litiro 10–20 ku munota ku munota munini. Iryo pompa ni ikintu gitoyi ca 400 W chabrot kigenda ku 12 V. Iba munsi y’ibarabara canke mu gipfukisho.
Uwo munyamigezi yicara imbere y’ibarabara rya A/C. Ku muvuduko w’umuhanda uronka umuyaga mwinshi, ariko wicaye kuri Supercharger ku musi w’amadegre 110 F i Barstow umufana w’umuyagankuba utegerezwa gukwega cane. Ni co gituma Tesla yongeyeko akarongo gatoyi k’ivyuma mu myaka mikeyi iheze -kureka umucuzi aguriza ifumbire ikanye mu nzira ya A/C iyo ishushe vy’ukuri.
Ivyimburwa vy’ubushuhe ni vyo bica. Iyo ingingo ikonje cane ari 25 degre 25℃kandi ishushe ni 40℃utakaza kumbure 15–20 % y’ubuzima bw’inzinguzingu. Rero manifold manifold itegerezwa guca ibice nk’uko bimeze. Amashirahamwe amwe amwe y’amashini imashini aratomora mu ishami rimwe rimwe. Abandi baratuma gusa imigende miremire kandi y’urukoba rero inguvu z’ugutemba zingana n’ugutemba. Igipande c’uruzitiro rwa BYD gikoresha igikonjesha ku ruhande rurerure rw’ingingo aho gukoresha uruzitiro rw’imbere{9}} rusaba ko ruhuye neza.
Igihe c’ubukonje nta n’umwe yavuga mu 1999. Hasi nk’amadegre 0 ntushobora gucagura ningoga canke wica icuma c’ivyuma. Rero iyo nzira nyene ikonjesha ubu itegerezwa gushuha. Igikoresho co gushushanya 3–5 kW PTC kiri mu kigega canke inyuma y’ipompa nyene. BMS iraba amashanyarazi y’ingingo nk’isonga mu gihe c’ubushuhe.
Igiharuro ni 1–1,5 igipimo c’ibarabara. Gutuma umuntu agira uburebure bugera kuri 115–120℃rero ntuzokwigera uronka imifuko y’umwotsi iyo ingingo ifashe ingingo yo kuja hanze y’umubiri.
Twarakoresheje 30- module ku ntebe umwaka uheze kuri JPL. Igihe co gukonjesha cavuye kuri degre 25 gushika kuri 65 mu minota umunani ku 200 A isohoka. Hindukiza ipompo ku 12 L/min maze ishika ku 38℃. Iminota umunani n’itigera-ni co gituma pack yose ikomeye ifise amazi ubu.
Iyo ni yo shusho y’ishimikiro. Ivyo bimenyetso birahindura umwaka wose w’akarorero, ariko fizike ntiyigira.
