Hello, I am working on a regenerative wheel hub design for an EV. This is not a regenerative braking system, nor is it a violation of the conservation of energy idea. The idea encompasses using the rotating mass of a wheel to provide a trickle return charge to the battery pack as a wheel is rotating while driving. Problems: Placing the magnets too close to the stator produces a magnetic pulse resistance (drag). Placing them too far away, leads to no magnetic impulse to the pick up coil(s) (no benefit) The idea is to modify a hub, and mount the molybdenum permanent magnets in it. Then mount the stator to the part of the hub that doesn't move. With a little trial and error adjust the gaps of the stator to rotor interface to cause the least amount of magnetic resistance. Yet close enough to still cause an electric pulse in the coils, while not adding significant drag to the driven wheel should cause a charging circuit. Having this mounted in the center of the wheel will reduce mechanical drag due to mechanical advantage. In theory, this should provide a minimal source of drag on the wheel, and provide a source of trickle charging energy to the electrical system. The idea is to capitalize on the moving parts, and potentially wasted potential energy sources. Over the entire charge duration of the battery pack this should add an extended range, even if it is a small increase. The stator, produces 12volts and unknown amperage. When attached to an engine it will supply all the energy for all needed lighting plus battery charging, in its OEM application. So it should be sufficient to use for a charging circuit. In an overdrive scenario the wheels actually spin faster than the crankshaft of a ICE. So freeway speed (60-70MPH) should generate some pretty good charging rates. Nothing compared to the expenditure. But Im after extending range, not running the car on it. Regenerative braking claims horrible returns of 15% or so. The idea of charging whenever moving is potentially useful. So please correct me if Im wrong, but if this system were attached to each wheel should it not help to extend range? I do understand that if improperly set up it would hinder range. Even a 10%(thinking big here) increase over the range of the battery charge could be significant. What would be the minimum needed charge rate to cause any effect. Use generals. Thoughts?
