ABSTRACT:
A system for measuring voltage of individual cells connected in series includes a single flying capacitor. The capacitor stores the charge of one of the cells such that an analog-to-digital converter (ADC) connected to the capacitor may process an accurate representation of the voltage of the cell being measured. A plurality of MOSFET-based switches electrically connects and disconnects the cells and the capacitor. A controller is in communication with the ADC and the switches for sequencing the switches and recording the voltage measurements of each cell.
