The article says FDK's mass produced lithium ultracapacitors are 14 W*h/kg, which is 14*3.6kJ/kg or 50.4 kJ/kg=0.05MJ/kg. This sounds really pathetic, until you consider 10kg is 504kJ. 1/2*1200kg*(30m/s)^2=540kJ. For reference, 30m/s is 67mph. If you try to Ebay ultracapacitors or google some suppliers, the only ones I could find at least were like 5 times worse in terms of energy density. Anyways, enough energy to get from 0 to 60 in a BRZ in something 2/3 the weight of the stock lead acid battery is pretty good, not to mention the huge number of cycles they can survive and being able to be fully discharged and charged in seconds. And these are only the beginning, the newer ones have like 3 times more energy density. I like this kind of technology  |
mild hybrids?
good luck subaru...
imo they are SO far behind in hybrid tech its not funny. unless of course
everything is behind the scenes and they somehow come out with revolutionary stuff seemingly outta nowhere... but again, toyota owns like 15% of FHI or something like that. if FHI has such cool tech, toyota may use it for themselves....
