Comments on: GM Says EEStor-Powered Chevy Volt Would be Possible, if EESU Was

I’ve heard the (allegedly) leaked interview with Dick Weir in which he claims they (Eestor) has begun assembling modular production lines. It has also been independently confirmed that Eestor has requested UL certification of its technology. Then there is the fact that they’ve purchased the rights to what I believe us the largest barium titanate mines in the U.S. Obviously, at the time of this writing (Jan 01, 2010) 2009 has come and gone and still no Eestor ESU’s. Still, I think there’s a good chance that they will deliver working ESUs soon — otherwise, what’s the point of having bought the mines?

Herm: ...Level 2 = 240VAC at 70A (the new J1772 connector will handle this)... Level 2 can do 60 miles.

The solution sounds pretty simple to me if the problem is the individual connector electrical transfer capacity. Do like I do when I'm filling up my dual tank diesel truck. Use 2 pumps! I pull up perpendicular to the end of a set of pumps and grab one handle from each side of the pump and pump both tanks at the same time. Doubles my refueling rate. No problem. If you are charging at 60 miles every 60 minutes using just a single lowly level 2 connector that every sane person would agree is perfectly safe, 10 connections will give you 100 miles of range in 10 minutes. Jump up to a 480 volt 3-phase connector (which in reality is just as safe) and you cut the number of connections and increase the number of miles you can charge in 10 minutes to a completely reasonable amount of time and connections. All you have do to is design whatever you are charging to be charged in parallel instead of in series, and provide connections for multiple off-board charging units that connect to multiple banks of whatever it is you are charging. There is no need to have huge single connectors when a couple of smaller connectors can work perfectly fine. Leave all the heavy electrical connections somewhere in the back of the charging station. It is no more a hazard than the electricity distribution that feeds hundreds of houses in a subdivision all at the same time today. Yawn....

Exciting times in battery news…….many claims of breakthroughs
sooner or later there is bound to be some due to all the increased research in battery technology……….
I hoping EEStor is successful soon or
Microbubble Technologies (ECOLOCAP) carbon nanotube lead acid battery or ERRA’s YESS battery (nickel Hydrogen)
all claiming breakthroughs……….10x capacity of lead acid, quick 10 minute recharges and long life
