SMRGL: Automobilka nic takovýho udělat nemůže. Automobilka musí napsat dojezd dle metodiky WLTP, stejně jako automobilka píše spotřebu dle WLTP.

Žádnou jinou spotřebu/dojezd udávat nesmí.

toto by bolo vtipne, keby to nebolo smutne

"Tesla is delivering around 100kwh batteries, and getting close to 390 miles from that pack.

GM announced a battery architecture supporting 50–200kwh packs, and “up to 400 miles” range.

So their 200kwh pack is getting 10 more miles than Teslas 100kwh pack."

KEB: Mrkni na tohle: COMODOR_FALKON

SEJDA: To by se taky dalo udělat měření reálnýho dojezdu dle WLTP v zimě a dojít ke stejnýmu závěru.

KEB: oni ale nezmerili "o kolik je dojez mensi v zime" ale jenom "o kolik je mensi" .. ze bude dojezd mensi se da cekat. Na to abys urcil "v zime" potrebujes jeste jedno mereni, ktere neni "v zime"

KEB: to pisal nejaky expert na zlomky "Test zjistil, že elektromobily v průměru ujedou v zimním počasí o 18,5 procenta kratší vzdálenost, než jakou výrobci uvádí v parametrech, tedy skoro o čtvrtinu. "

mne to teda vychadza necela petina, ale vedel by som to zaokruhlit aj na polovicu :D

Samsung Presents Groundbreaking All-Solid-State Battery Technology to ‘Nature Energy’
2020.03.10

On March 9 in London, researchers from the Samsung Advanced Institute of Technology (SAIT) and the Samsung R&D Institute Japan (SRJ) presented a study on high-performance, long-lasting all-solid-state batteries to Nature Energy, one of the world’s leading scientific journals.

Compared to widely used lithium-ion batteries, which utilize liquid electrolytes, all-solid-state batteries support greater energy density, which opens the door for larger capacities, and utilize solid electrolytes, which are demonstrably safer. However, the lithium metal anodes that are frequently used in all-solid-state batteries, are prone to trigger the growth of dendrites1 which can produce undesirable side effects that reduce a battery’s lifespan and safety.

To overcome those effects, Samsung’s researchers proposed utilizing, for the first time, a silver-carbon (Ag-C) composite layer as the anode. The team found that incorporating an Ag-C layer into a prototype pouch cell enabled the battery to support a larger capacity, a longer cycle life, and enhanced its overall safety. Measuring just 5µm (micrometers) thick, the ultrathin Ag-C nanocomposite layer allowed the team to reduce anode thickness and increase energy density up to 900Wh/L. It also enabled them to make their prototype approximately 50 percent smaller by volume than a conventional lithium-ion battery.

This promising research is expected to help drive the expansion of electric vehicles (EVs). The prototype pouch cell that the team developed would enable an EV to travel up to 800km on a single charge, and features a cycle life of over 1,000 charges.

As Dongmin Im, Master at SAIT’s Next Generation Battery Lab and the leader of the project explained, “The product of this study could be a seed technology for safer, high-performance batteries of the future. Going forward, we will continue to develop and refine all-solid-state battery materials and manufacturing technologies to help take EV battery innovation to the next level.”
