6 minute charge still on the agenda....

Extra Fast Charging ResultsThe FCprogram previously announced on 22 June 2021 recently ended in a huge success.The program used 2-3Ah cells which had a retention rate of over 60% at 2C-2C rates (30 min charge and 30 min discharge) after over 6000 cycles and at that point the decision was made to fast track the EFC program using larger commercial cells. There were minor delays in the installation of high voltage power into the building to run these tests as the charge current needed is as high as 70 Amp. The EFC program has cells currently running with a 15 min charge and variable discharge rate as part of initial test protocols. To date the results received have been very exciting with over 250 cycles achieved without any capacity loss. 31 DECEMBER 2021
The plan is to take this program to over 3000 cycles and then run new programs at a higher current to achieve a 10-minute charge and then onto a 6-minute charge. The optimised cell is still within 95% energy density of a regular energy cell, which means minimal energy density loss. Such high-power density without any Cobalt and Nickel for a Non-LFP cell makes C4V’s technology a leader in the marketplace.The tests were done at 90% DOD which equates to a maximum energy being infused and withdrawn during charge and discharge cycles. These cells were made with standard scalable processes as well as materials used from highly qualified suppliers which will allow the scale-up of the technology with limited variability leading to a speedy launch in the marketplace. Figure 1: Optimized EFC 7Ah cell cycling dataSignificance of ResultsIndustriesthat require EFC or FC include the transportation industry as they areconstantly on the road and the results announced today could be a game changer for them. The real significance comes from the number of cycles coupled with the charging times. Traditionally batteries used in the EV industry currently have up to 80% retention afterapproximately 1,0 00 cycles using lower charging rates. When constant fast charging rates are applied the battery life decreases dramatically. Today’s results show no capacity loss after 250 cycles using a 15-minute charge.

LOL some people will believe anything. Based on their figures the xfc battery has gone backwards.

It started out at 6 minutes, now its gone to 20 minutes. Hardly progress. oh noooooo

I guess the solid state battery due to go into production in 2019 is still on the agenda along with all the other things.
The Dubbo big battery etc etc etc.
