Improvements to the Car Battery

[KimberlyRPeacock]

Am I wrong? It seems to me that putting the ultracaps in a microprocessor switching fabric inline with a batter which would form an LC circuit, would address the voltage drop issue, and allow quick recharge. The battery becomes the L in the LC circuit.

One thing he forgets to mention is that the voltage on the cap is essentially related to capacity. This means that charged to 10V if you discharge to 50% you only have 5V to run your motor, where as if you discharge a battery to 50% you still have about 80-90% of the voltage. This means that if you need a minimum of 10V to run your motor you need it charged to 100V to be able to discharge to 10%. Also you then need to waste a lot of energy to keep the operating voltage below ~12V when charged.

any further prototype ultracapacitor battery since last about two year .

if you know anything about the oil industry then you know this will never ever ever ever ever happen. Don't believe me, start reading up on people that have been shot, murdered etc because they came up with ways to generate free energy. All this guy is doing is trying to improve the battery, watch a video called "who killed the electric car" to see just why this will never happen.

yes, as far as I know the problem with discharge still exists and has not been complately fixed yet.

Where did you get the info?

Ultra Capacitors don't Have to discharge fast, they can discharge slow just fine.

I find it disturbing that a professor at MIT speaks so confidently about things he does not know. Any Prius owner that knows the minimum tech details about it knows that the SOC window is between 35% and 80%. This means 45% of total capacity, and not 10% like Prof. Joel states. Another thing is that ultra-capacitors charge and discharge fast. The trouble is to discharge slow, as cars need it to do. You're not feeding a rocket, you need to dose the rate of discharge. Basic stuff.
