Abstract
The auto industry is progressing towards hybrid and fully electric vehicles in their future car models. These vehicles need a power plant that is reliable during the lifetime of the car. Battery and ultra-capacitor capacity imbalances stemming from manufacturing and ensuing driving environment and operational usage affect voltage levels, which must adhere to strict limits to ensure the safety of the driver. A double-tiered capacitive shuttling technique is applied to an idealized three-battery system simulation in order to balance the voltages. Parameters in the system are varied and their effects on the system determined. Results are compared to a single-tiered approach. Simulation shows a substantial improvement in charge transport using the new topology. Experimental results verifying simulation are presented.
