Abbreviated Dev Diary: Flux Seven B

"eBoost" and the Flux Seven B:

The Flux Seven B is an electric vehicle and as such traditional methods of performance tuning are no longer appropriate.  For an extra burst of speed for a set of "boost capacitors" are available to pour extra power into the electric motor.  Whereas a battery provides a constant, even flow of power at a set output, a capacitor can store energy from an incoming electric input and release it at a faster, more concentrated rate.  

A good metaphor for the eBoost concept may be a slow flowing garden hose.  The water coming from the hose would be equivalent to a battery's output.  If the hose slowly filled up a bucket, the bucket would be a capacitor.  If the bucket is filled and then dumped all at once the result is more dramatic.

The boost capacitors slowly charge from regenerative braking and a set allowance from the main battery.  They can be activated by the driver when full and can provide a roughly 30 HP boost for up to 10 seconds per charge.  Once expended, the capacitor can begin recharging again.
