Abstract
One or more aspects of the present disclosure are directed to a synchronized actuation system for holding samples (e.g., battery cells) in place such that ultrasonic sensors can make physical contacts with the samples to transmit and receive acoustic signals across the samples for purposes of making ultrasound measurements of the battery sample. The movement of sensors on both sides of a sample can be synchronized (as opposed to being handled via independent actuators) to improve signal repeatability.
Claims20
A system for performing acoustic measurements on battery cells, the system comprising:
- a plurality of transmitting sensors configured to transmit acoustic signals across a sample;
- a plurality of receiving sensors configured to receive response signals through the sample in response to the acoustic signals transmitted therethrough;
- and
- an actuator configured to synchronously actuate the plurality of transmitting sensors and the plurality of receiving sensors to provide same spacing and speed of motion between the plurality of transmitting sensors and the plurality of receiving sensors relative to the sample.
A system comprising:
- a controller including one or more memories having computer-readable instructions stored therein, and one or more processors configured to execute the computer-readable instructions to:
- determine a location of a sample relative to a holder mechanism, wherein the holder mechanism is configured to hold the sample to be acoustically measured using a plurality of transmitting sensors and a plurality of receiving sensors;
- and
- generate one or more commands for actuating synchronous movement of the plurality of transmitting sensors and the plurality of receiving sensors such that the plurality of transmitting sensors and the plurality of receiving sensors come into contact with the sample at a same time for acoustic measurement of the sample.
