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. An exemplary sensor arrangement includes a number of sensor units, a controller, and several connections, wherein two or more sensor units are coupled to each node of the battery pack and are coupled to the controller over different connections. An exemplary method is divided into two aspects: an error detection aspect and an error resolution aspect. Because the sensor arrangement provides multiple sensor readings for each node being evaluated, the method can enable the sensor arrangement to continue operating accurately and with redundancy even if it experiences a loss of one or more sensor units.
