Abstract
A system for monitoring battery cells of a battery includes a capacitor, a processor, and a controller. The controller is configured to connect the capacitor with a first battery cell to charge the capacitor to a voltage of the first battery cell and then (i) connect the capacitor with a second battery cell to form a circuit having an output that is a voltage difference of the capacitor and the second battery cell and (ii) connect the output to the processor for the processor to measure the voltage difference. The voltage difference is the voltage difference between the first battery cell and the second battery cell.
