Patent Images
1. An apparatus for measuring battery voltage comprising:
- a first capacitor configured to receive a charge from a battery;
a first switch configured to selectively couple the first capacitor to the battery;
a second capacitor having a terminal coupled to a reference potential; and
a second switch configured to selectively couple the second capacitor to the first capacitor to transfer at least a portion of the charge on the first capacitor to the second capacitor.

Abstract
An apparatus and method for measuring battery voltage includes a first capacitor configured to receive a charge from a battery. A first switch may be configured to selectively couple the first capacitor to the battery. A second capacitor may be coupled to a reference potential. A second switch may be configured to selectively couple the second capacitor to the first capacitor to transfer at least a portion of the charge on the first capacitor to the second capacitor.

12. A method for measuring battery voltage comprising the steps of:
-
selectively coupling a first, floating capacitor to a battery to allow charge to flow from the battery to the first capacitor; and selectively coupling a second, fixed-reference capacitor to the first capacitor to transfer at least a portion of the charge from the first capacitor to the second capacitor. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
