Note to reader: the supercaps in the article aren't being used for long-term energy storage.
When a car brakes using magnets, a huge quantity of power is generated by the magnets. In a typical setup, this power value is much higher than the maximum rate at which the lithium batteries can absorb charge.
From what I gather, what this article actually means is that these supercaps will be used as energy couplers between the regenerative brakes and the lithium batteries. They aren't actually replacing the lithium battery.
- redthrowaway 13y agoPresumably it'd work the other way, too? Supercaps that let you recover more of the energy produced by regenerative braking should also give you short bursts of acceleration, no? I imagine a system similar to the KERS system used in F1: http://en.wikipedia.org/wiki/Kinetic_energy_recovery_system http://en.wikipedia.org/wiki/Kinetic_energy_recovery_system
- jsilence 13y agoYeah, like a 1st level cache for energy.
