Abstract: The battery monitoring techniques described herein use a self-characterizing wireless monitor coupled to a battery to monitor different properties of the battery. The wireless monitor may measure, among other things, an alternating current frequency response (ACFR) of the battery. To accomplish this, the wireless monitor may generate and inject a stimulus signal into the battery, and the monitor may then synchronously measure the corresponding impedance response of the battery.

Abstract: Systems and methods permit automatic joining of a network associated with a specified area within which wireless nodes reside. Network managers located in or near the specified area use wireless proximity detection to estimate distances to wireless nodes requesting to join the network. The network managers can use the estimated distances to determine whether or not a requesting wireless node is located within the specified area. If the requesting wireless node is located within the specified area, the network managers can permit the wireless node to join the wireless network associated with the respective specified area.

Abstract: A wireless battery management system may include a network controller and a plurality of monitors coupled to a battery. The wireless battery management system may coordinate taking and gathering of alternating current frequency responses (ACFR) of the battery. The wireless battery management system may collect and store information spanning the lifecycle of the battery across different host devices.
