New techniques in battery charge equalization
"High-voltage energy storage systems,which employ large series strings of battery cells or ultracapacitors, can be found in many applications including the utility industry, power backup, and electric and hybrid vehicles. These vehicles need a power plant that is reliable and maintains integrity 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. While balancing the voltages of the batteries will prevent any problems stemming from capacity mismatch, there are many way to instantiate the solution. This thesis reviews, analyzes, and classifies various existing charge equalization techniques including capacitive, inductive, and transformer storage methods. In this thesis, a double-tiered capacitive shuttling technique is presented and applied to an idealized three-battery system simulation in order to balance the voltages"--Abstract, leaf iii.
