Abstract

See full text

A method for estimating the state of a battery having multiple cells is disclosed. In one embodiment, strain gauges are coupled to battery binding bands that hold cells of the battery together. The strain measured by the gauges may be related to the electrical charge stored by the battery. The method may improve estimates of battery state of charge during conditions when battery voltage changes little and the battery continues to accept charge.
