Hi Everyone, Lithium Ion, 18650, batteries are widely used in laptop computers and it is one of the most widely used lithium ion batteries. 18 is the diameter...
Hi Wayne, For sure there should be some "safety circuitry" used in conjunction with these cells as there have been some fires reported in laptops and model...
I suggest that further general discussions on this subject be addressed to other lists, e.g. gridable-hybrids or evworld. Of course, to the extent that...
This is very interesting info. I am chagrined to say I was completely unaware of it. Given that we are proposing to create a PRIUS+ formula and vehicle type...
You are aware, I take it, that Toyota has a version of the Yaris on sale in Japan that uses Lithium batteries? Presumably they are happy idiots that can cope...
... Bingo. ... The 2.2 or 2.4Ah 18650's they used cost more like $4 per cell, for a cost closer to $20,000 Plus labor and the BMS system... I have a few of the...
Look at the small capacity Kokam LiP cells on my metricmind site. If they work for Cliff Rassweiler to move his racing pure EV, they will be fine to give a...
1. I was not aware of any such vehicle, but it would suggest an area of research for us (to find out who makes the batteries and whether they could be...
Hi, everyone! It is time for a PRIUS+ project update. As you will see, we have a number of unknown factors. We hope to have more clarity and/or an operational...
Thanks for the update. deciphering the Toyota codes in the various modules is never a picnic!! Good luck. Maybe the problem is in the lead acid batteries...
My PRIUS+ is now running as a PHEV (though imperfectly)! First, the good news: last night I drove 9 miles electrically, including both lots of starts and...
Ron: It sounds like you are making progress!! good job! I wonder if some of your "noise" problems are due to the PbA battery anomalies that are different from...
Thanks again, Andy, for following our progress and for your idea (once again) re. PbA vs. NiMH battery voltage. Actually, the THS appears to be quite...
Wonderful! Congratulations! Regarding the noise: I would suspect that it has to do with improper termination or shielding or both. CAN interface, as you know,...
Ron: Have you seen the noise on an oscilloscope? You may be right about the battery being distributed and unshielded as the noise source but it is hard to see...
Thanks for your CAN bus suggestions Andy and Alexander. Toyota's Battery ECU appears to be at an end of the CAN bus. However, it does not appear to have a...
Several pieces of new data today (Tuesday, 11/23): Relative to the four problems in my last report: 1. The CAN bus noise appears to be gone as long as I...
Great news Ron! If the EV mode driving distance is large enough then the only reason(s) to run the ICE are lubrication and thermal considerations. This would...
Ron, I definitely meant 120 ohm. This is just a typo. Proper grounding and shielding can get very tricky. It sounds strange that you don't see a terminator in...
... Ron, from my own experience of working with a differential bus, there is definitely a need to terminate the bus at each end. Actually you can determine if...
We had already planned on per-cell active over- and under-voltage protection and equalization for an Li-ion pack, but I'm beginning to wonder if that is enough...
Howdy, I don't know which particular brand of Li-Ion batteries has the non-flamability additive that I mentioned in my previous post on Nov. 4th. ([priusplus]...
... These are silver zinc cells. A major limitation indicated at http://www.zmp.com/specialty.html is a deep cycle life of only 100 cycles. Tom Driscoll just...
