I was wondering if anyone had experimented with combining different battery chemistries into a single hybrid pack?

Not I, but it sure sounds like it could get very interesting.

Heck I am looking at an old 24 volt fork lift battery to use for my turbine when I get it up. That sir is very high tech for me.

CSIRO developed the capacitor lead acid battery, but I think you're talking lead acid/ LIfePo4 combo right?

I can see the same problems that are having you scratch you head and thus post the idea.

Different rates of discharge are going to be a problem.

Perhaps this for an idea. Most DC motors used in electric car type applications run a separate field winding and coil winding, perhaps -you could use a lead acid battery for one (the exitation) and the LiPo for the main juice.

I have no idea how much juice the field uses and hence if it uses very little then so be it not worth doing.

Also all the "other" bits, A/C power steering radio etc etc etc all need power which could be derived from the less expensive storage lead acid offers -again at the penalty of weight.

As far as different chemistries inside the one pack/cell
i'm thinking would be really tough, seems to me they have enough trouble with simple changes like the Calcium batteries, do some things better and others worse - highly application based.

What I do know is I have read Trev's spiel on your battery balancing solution and with some luck that has the potential to make you millions.

Patent it and build it or patent it and watch the $$ come in on royalties.

Best of luck, i'm following your interest in electric cars with great interest.

Hi Karl,

I am not having any problems, but it was a general question to others.

I had not really considered EV applications, as lead cells are a bit heavy for a mobile application, and LiPo alone would be a better solution. The batteries would not be hybrid in the same cells, but more along the lines of parallel groups of cells in a pack to exploit a particular aspect.

However Patent ideas is very expenives and not easy to get $$$ from royalties as l have my items patent 2004 got pinch by someone else and still on fighting on

I agree with Dwyer on patents, and have been around the patent merry-go-round.

With a patent in most cases a general 10% change will negeiate the rights, and then there is the area of "common knowledge".

Basically the paper it is written on is worth as much as a expencive dunny roll.

It is up to the patent holder to challenge any conflict of interest and prove their case....and that costs a fortune.

So if you dont want it stolen, then dont tell anyone and stay poor or it will make you poor trying to keep it.

I am going round and round with my wife right now over the jigs I make for reloading ammo. She and many others have told me that I am crazy for not patenting my jigs. I had a friend who went through that process years ago and the head aches he had trying to get it done to only in the end cost him more then he ever made from it. To me it's just not worth the hassle.

Mac Gyver's View On Patents

I've always thought everything should be free. I know it's an unpopular position, but it's something I learned in kindergarten and I think if we all practiced the idea, the world would be a better place.

The premiss is this: Life is best when we take a nap mid day, there's no argument that can't be settled over a glass of milk and a cookie and share the big wooden blocks.

It's that "share the blocks" part I'm referring to here. Patents serve only to keep stuff out of others' hands. It's the opposite of "sharing the big wooden blocks" in my way of looking at it. In its extreme application, it borders on out and out greed.

I'd rather see all information made public property and if someone likes an idea and wants someone else to use the information to build whatever it is for them, then they could pay for the labor and talent, but I believe the basic information should be free.

This probably belongs in "Rants and Raves" but it fits in here and I'll just step down off my soap box and leave it alone now.

I think Mac meant the basic information should be free not "Everything free"

My point being, that if a person had an idea to either improve something or better yet, invent something new.
But he had to put the information out there for all to use with no return to him, then why even try to invent anything. This is what leads to mediocrity, and in the end everyone looses.
