Kev txhim kho thiab kev tsis sib haum xeeb ntawm kev them nqi

Thaum Lub Kaum Hli 2011, xya lub tuam txhab tsheb loj hauv Tebchaws Meskas thiab Lub Tebchaws Yelemees tshaj tawm tias lawv lub tsheb hluav taws xob yuav raug sim nrog cov qauv kev them nqi sib koom ua ke. Xya lub tuam txhab no yog Audi, BMW, Daimler, Ford, General Motors, Porsche, thiab Volkswagen. Tom qab ntawd, Lub Koom Haum ntawm Automotive Engineers (SAE) tau tshaj tawm tias nws tau tsim lub ntsaws uas tuaj yeem tsim nyog rau ob qho tib si thawj thiab theem nrab them cov qauv. Peb-theem DC them ceev ceev tuaj yeem them koj lub tsheb fais fab roj teeb hauv 15 feeb. Hauv qhov kev them nyiaj thib ob (110 volts hauv Tebchaws Meskas), lub sijhawm them nyiaj yog kwv yees li 4-6 teev nyob ntawm tus qauv tsheb. Cov xya lub tuam txhab no tau mus txog tus qauv pom zoo rau cov khoom siv them nyiaj, uas kuj tau sib xws nrog SAE's J1722 charging standard thiab European IEC 62196 Class II sockets.
Xya lub tuam txhab tsheb European thiab Asmeskas no tau pom zoo los siv HomePlug GP interface thev naus laus zis ntawm Lub Tsev Hluav Taws Xob Hluav Taws Xob Network Alliance ua cov txheej txheem sib kis, uas tso cai rau kev them nyiaj sib koom ua ke rau hauv daim phiaj ntse yav tom ntej. Lub HomePlug Power Line Alliance yog tsim los ntawm cov tuam txhab semiconductor, cov tuam txhab siv hluav taws xob, cov tuam txhab lag luam, thiab lwm hom tuam txhab. Cov tswv cuab suav nrog ntau lub tuam txhab thoob ntiaj teb, xws li Cisco, Fabkis Telecom, Tuam Tshoj Huawei, thiab lwm yam. Cov tuam txhab no koom tes tsim, tsim, thiab txhawb cov thev naus laus zis tshiab thiab cov ntawv thov uas tuaj yeem txhim kho lub zog thiab kev sib txuas.
Chademo tus qauv DC lub chaw them ceev ceev tuaj yeem them txog 80 feem pua ​​​​hauv 30 feeb. Hom kev them nyiaj ceev no yog pom tseeb ntau dua li cov khoom siv hluav taws xob sib txuas, tab sis nws txoj haujlwm yuav tsum muaj lub zog tam sim ntawm 50 kilowatts los ntawm daim phiaj hluav taws xob, uas tau ua rau muaj kev txhawj xeeb txog daim phiaj siab. Yog li ntawd, Chademo tus qauv DC them ceev tsis yog ib qho kev daws teeb meem rau kev them nyiaj hauv tsev. Tus qauv SAE them tus qauv siv HomePlug GP thev naus laus zis los faib hluav taws xob hauv tsev kom tsim nyog, kom ntseeg tau tias cov khoom siv hauv tsev tsis cuam tshuam [4]. Wireless kis tau tus mob technology yog ib tug technology uas siv wireless technology los xa hluav taws xob lub zog, thiab ntau lub teb chaws tab tom tsim xws li wireless charging li.
Thaum lub Cuaj Hlis 2022, cov kws tshawb fawb los ntawm Harvard University tau tsim ib hom tshiab ntawm cov roj teeb lithium-hlau rau lub tsheb fais fab (EVs). Lub roj teeb tau ua tiav kev them nyiaj tsis pub dhau 3 feeb hauv kev sim, tuaj yeem ua haujlwm ntau dua 10000 zaug ntawm nws lub neej, thiab tuaj yeem kav ntev txog 20 xyoo. Thaum Lub Kaum Hli, cov kws tshawb fawb ntawm Pennsylvania State University hauv Tebchaws Meskas tau tsim cov qauv roj teeb tshiab uas ua kom tiav lub tsheb fais fab hauv kaum feeb.
