I see Mitsubishi and Honda are doing local market testing with LTO chemistry cells in the iMiEV and Honda in the Fit hybrid .... although it looks...
The cells arrived a while ago and today, the Prius finally went on the tilt tray truck to the repairers/assessors to see if I get an insurance...
The cylindrical cells are 55Ah Yinlong brand. The charge rate is 4CA and discharge rate up to 10CA. The energy density isn't as good as other...
The voltage maintained between 240vdc and 250vdc is interesting. On another thread, a member is trying to develop a traction battery using...
My Engineer system using 76 x 40Ah LFP cell extended range pack did 80km/h 50 km a few times, but the pain of driving at 80km/h was just too much...
Time will tell, the cell damage becomes apparent after 12 mths to 2 yrs, but can be even less time than that. The capacity drops so the problem is...
This is the principle I was talking about earlier on in this thread, around 18th of last mth. The E Fluids developed for the F1 electric vehicle...
4.0v per cell is fine as long as you have a balancing system that can move the high high regen current from the cells that have already hit 4.0v...
Takes a bit to get the head around the graph recording negative HV Bat current on regen, but interesting to see it changing the current in an...
I agree with Bisco, that sounds very much like a 12v circuit problem. When I was limping my '06 Prius to the workshop, I hit a bump and the whole...
Sorry, I didn't that you for posting that info, much appreciated. T1 Terry
That's interesting, even the same colour as mine :eek: I at least got the fire out before and actual vehicle damage occurred and well before it...
Are you just trying to make me feel better :lol: When the traction battery was on its last legs in the '06 Prius, I did see 280v as battery...
I thought I posted a reply to this, but it must have gone off to the ether or some where. I'll try again. That is handy info, thank you, roughly...
3.3v is somewhere between 90% SOC and 50% SOC ..... if the cells hold 3.4v or better over a number of days, then you have achieved full charging...
Been extra busy working doing lithium off grid installs, it's put these "projects" on the back burner. With the single cell, I tried a number of...
This is just one of the "E" fluid cooling ideas out there, a lot of player in this new market...
The "E" fluids were developed especially for battery and motor cooling in the F1, Formula E and other race type vehicles where the battery gets a...
I plan to build a 55Ah LTO battery for my Prius that had the traction battery go up in smoke (and flames and bangs and pops) It will take up the...
A very interesting experiment. I steered away from using LiFeP04 (LFP) chemistry because they don't handle anything much more than 1CA charging...
