Abstract
Systems and methods for analyzing physical characteristics of a battery include arrangements of two or more transducers coupled to the battery. A control module controls one or more of the two or more transducers to transmit acoustic signals through at least a portion of the battery, and one or more of the two or more transducers to receive response acoustic signals. Distribution of physical properties of the battery is determined based at least on the transmitted acoustic signals and the response acoustic signals.
Claims20
An apparatus comprising:
- a plurality of transducers;
- a controller configured to control,
- one or more of the plurality of transducers to (1) generate an acoustic signal having one of a plurality of different shapes of wavefronts and (2) transmit the acoustic signal through at least a portion of a battery, and
- two or more of the plurality of transducers located at corresponding two or more positions across a cross section of the battery to receive acoustic response acoustic signals in response to transmission of the acoustic signal through at least the portion of the battery;
- and
- an analyzer configured to determine one or more physical properties of the battery based on the acoustic response signals at the two or more transducers located at the corresponding two or more positions.
A method of battery analysis, the method comprising:
- controlling one or more of a plurality of transducers coupled to a battery to (1) generate an acoustic signal having one of a plurality of different shapes of wavefronts and (2) transmit the acoustic signal through at least a portion of the battery;
- controlling two or more of the plurality of transducers located at corresponding two or more positions across a cross section of the battery to receive acoustic response signals in response to transmission of the acoustic signal through at least the portion of the battery;
- and
- determining one or more physical properties of the battery based on the acoustic response signals received at the two or more transducers located at the corresponding two or more positions.
A non-transitory computer-readable media comprising computer-readable instructions stored therein which, when executed by one or more processors, cause the one or more processors to:
- control one or more of a plurality of transducers coupled to a battery to (1) generate an acoustic signal having one of a plurality of different shapes of wavefronts and (2) transmit the acoustic signal through at least a portion of the battery;
- control two or more of the plurality of transducers located at corresponding two or more positions across a cross section of the battery to receive acoustic response signals in response to transmission of the acoustic signal through at least the portion of the battery;
- and
- determine one or more physical properties of the battery based on the acoustic response signals received at the two or more transducers located at the corresponding two or more positions.
