Abstract
A sensor arrangement and method that may be used with a variety of different energy storage devices, including battery packs found in hybrid vehicles, battery electric vehicles, and other types of vehicles. Some battery monitoring systems, such as those designed to monitor and/or control lithium-ion battery packs, may require individual voltage readings for each and every cell. If a battery monitoring system component—even one that provides just one of these sensor readings—malfunctions or otherwise experiences a fault condition, then it may be necessary to bring the entire vehicle in for service. The exemplary sensor arrangement and method may be used to control a series of balancing switches in the sensor arrangement in such a way that enables the vehicle to detect fault conditions and to continue operating successfully in the event that such fault conditions occur.
