Sensor arrangement and method of using the same
First Claim
1. A method of using a sensor arrangement that evaluates an energy storage device, comprising the steps of:
- (a) receiving a first sensor reading from a first sensor unit at a controller, wherein the first sensor reading pertains to a parameter for a node of the energy storage device;
(b) receiving a second sensor reading from a second sensor unit at the controller, wherein the second sensor reading also pertains to the same parameter for the same node of the energy storage device; and
(c) using the first and second sensor readings pertaining to the same node parameter to detect an error with the sensor arrangement and/or the energy storage device.

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.
