Abstract
Official abstract text for this publication.
A system that balances voltages between battery banks. The system includes battery banks, including a first bank and a second bank, and a first capacitor. The system also includes a first set of switching devices which selectively couple first and second terminals of the first capacitor to first and second terminals of the first bank, and to first and second terminals of the second bank. The system includes a clocking circuit which generates clock signals with substantially non-overlapping first and second clock phases. This clocking circuit is configured so that during the first phase the first and second terminals of the first capacitor are coupled to the first and second terminals of the first bank, respectively, and during the second phase the first and second terminals of the first capacitor are coupled to the first and second terminals of the second bank, respectively.
First claim
Opening claim text (preview).
What is claimed is: 1. A system that balances voltages between battery banks, comprising: a plurality of battery banks, including a first bank and a second bank; a first capacitor with a first terminal and a second terminal; a second capacitor with a first terminal and a second terminal; a first set of switching devices which selectively couple the first and second terminals of the first capacitor to first and second terminals of the first bank, and first and second terminal…
