Sisitemu yo gukonjesha ni iki?
Ikibazo cya James Wong, Fremont, California.
Nkora kuri GM ishaje - Toyota NUMMI hano kandi twumvise ko umunsi umwe tuzubaka imodoka yamashanyarazi. Abantu bakomeza kuvuga kubyerekeye gukonjesha bateri. Niyihe nkuru nyayo?
Yashubijwe na Richard Flagan, Porofeseri w’Ubwubatsi n’Ubwubatsi bw’ibidukikije, Caltech.
(Nkora akazi ka aerosol ahanini, ariko nakwezwe mumishinga ibiri ya batiri hamwe na JPL hamwe namasosiyete yimodoka vuba aha.)
Lithium - ipaki ikora ubushyuhe butangaje iyo uyisunitse. Ipaki ya 60 kWh kuri 3C yishyurwa irashobora guta ubushyuhe bwa 15-20. Nibikoresho bito bishyushya biruka imbere yimodoka. Mubireke wenyine kandi selile yo hagati ikubite dogere 60 mugihe ukomeje kugerageza kwishyurwa 80%. Ubuzima bugabanuka vuba hejuru ya dogere 45, ugomba rero gukuramo ubushyuhe.
Amapaki menshi ubu akoresha isahani ikonje ya aluminiyumu ikonje igera kuri mm 4-6 z'ubugari hamwe n'umuyoboro wa kashe imbere. Uranyerera isahani imwe hagati ya module ebyiri cyangwa munsi yumurongo wa pouches. Isahani yuzuyemo urwego ruto rwa paste yumuriro hejuru ya selile. Amashanyarazi ya Ultium ya GM ni nkayo. Tesla yakundaga guhinduranya umuyoboro uzengurutse munsi ya 18650 na 2170 muri zigzag - isa na spaghetti, ikora neza, ariko biraterana guterana. Ipaki nshya 4680 muri Texas yagiye kumurongo mugari aho kuba umuyoboro uzengurutse. Biroroshye gusudira.
Coolant hafi ya 50/50 amazi - glycol hamwe na inhibitor zisanzwe. Imodoka zimwe zo kwiruka prototype zikoresha glycol nziza cyangwa se amavuta ya silicone, ariko ntamuntu wohereza abakiriya. Ubusanzwe gutemba ni litiro 10-20 kumunota kumupaki munini. Pompe nikintu gito 400 W kitagira brush gikora kuri 12 V. Ituye munsi yumutwe cyangwa muri frunk.
Imirasire yicaye imbere ya A / C. Ku muvuduko nyabagendwa ubona umwuka mwinshi, ariko wicaye kuri Supercharger kumunsi wa dogere 110 F muri Barstow umuyaga wamashanyarazi ugomba gukurura cyane. Niyo mpamvu Tesla yongeyeho octopus ntoya mumyaka mike ishize - ireka chiller iguza firigo ikonje muri kabine A / C mugihe ishyushye rwose.
Ubushyuhe bukwirakwira ni umwicanyi. Niba selile nziza cyane ari dogere 25 naho ubushyuhe ni dogere 40 uratakaza wenda 15-20% byubuzima bwikizamini. Inlet manifold rero igomba gutandukana neza. Ibigo bimwe bikora imashini ntoya muri buri shami. Abandi bakora gusa imiyoboro miremire kandi yoroheje kuburyo igitutu kigabanuka imbaraga zingana. URUPAPURO RWA BYD rwifashisha ubukonje kuruhande rurerure rwakagari aho hepfo - rusaba uburinganire bwiza.
Ubukonje nigice umuntu atigeze avuga muri 1999. Munsi ya dogere 0 ntushobora kwishyuza vuba cyangwa ugashyiraho icyuma cya lithium ukica selile. Umuzingo umwe rero ukonje ubu ugomba gushyuha. Ubushyuhe bwa 3-5 kW PTC bwicaye mubigega cyangwa nyuma ya pompe. BMS ireba voltage ya selile nka hawk mugihe cyo gushyuha.
Ubusanzwe igitutu ni igipimo cya 1-1.5. Komeza ingingo ibira hejuru ya dogere 115-120 kugirango utazigera ubona umufuka wamazi niba selile ifashe icyemezo cyo kujya hanze.
Twakoresheje module 30 - selile ku ntebe umwaka ushize kuri JPL. Hamwe no gukonja yavuye kuri dogere 25 igera kuri dogere 65 muminota umunani kuri 200 A isohoka. Hindura pompe kuri 12 L / min hanyuma itura kuri dogere 38. Iminota umunani ntanarimwe-niyo mpamvu buri paki ikomeye ifite ubukonje bwamazi ubungubu.
Iyo niyo shusho y'ibanze. Ibisobanuro bihindura buri mwaka wicyitegererezo, ariko physics ntabwo.
