Why NMC/LMO/LCO over LFP on OEM EVs? Due the cell cost. LFP base patents are still valid for few years while others are free game. Sometimes I feel they also wanted to make shitty solutions to prove EVs are no-go. You just got to love how Tesla is wiping floor with those arrogant a*#%¥£es. :)
When comparing Chinese LFP providers it's good to remember the original developer of this tech. Nearly all prismatic cell manufacturers are originally TS license factories. TS provided tech to all of them. Then many of the factories (couple dozen) have taken their own path. Many of them have not continued to buy raw materials from TS and have started their own development. Many buy LFP from other vendors who build very different LFP. Cells may perform better and give more power but we are after calendar life. We've proven 10 years on the road on customer cars (with super good BMS made by yours truly and MetricMind Victor). Also TS has mastered the water based slurrying over a decade and only now others have started to adopt it. The GigaFactory solvent recuperation process is another way to find cost efficiency but it takes space and requires more investment. TS water slurry coaters fit 8x more production capacity in the same space and no VOC! There is also now a major change coming to the production process which may (if successful) 30-fold the producion speed. TS aims to have the best cost efficiency so there is no excuse for anyone not to go for EVs. The inventor of TS is an EV geek just like us. Also very nice and warm hearted person. He always tries to do the best to serve us but due the good will too many exploit it and there is just so much one man can do. It's not his or his products fault if cells go smokey with no BMS. We have been looking vast amount of solutions how to integrate BMS to the cell and there are now few very good options we will test extensively out. It would also be benefical to have formation data on the chip so it's easier to see how the rest of the formation is completed after installation. Yes. It takes several hundred cycles to 'build' so it matters quite alot how you use cells when you pull them out from the box. Other manufacturers cycle more and age the cell longer. TS let's you decide how you do it. Your BMS will in most cases do it for you. Never go without BMS. Also never use s€&@t for BMS either. Use good and well tested ones. If you have still working TS cells in the pack replace the broken ones with new similar cells and add good BMS. Then drive with smile :) -Jukka sunnuntai 14. elokuuta 2016 EVDL Administrator via EV <ev@lists.evdl.org> kirjoitti: > On 13 Aug 2016 at 17:35, paul dove via EV wrote: > > > I have seen very little evidence of such.
