Application Cases

In recent years, with the continuous development of the economy and society, new energy vehicles have become the focus of the global automotive industry. Batteries, as the "heart" of electric vehicles, are also a hot topic in the industry. The preferred battery at present is the lithium-ion battery. During the process of multiple charge-discharge cycles or long-term storage, the capacity of lithium-ion batteries will deteriorate. Improper use and operation in harsh environments can also increase the likelihood of battery failure, which can easily lead to safety accidents. Therefore, using ultrasonic technology to detect the condition of batteries can help identify internal faults in a timely manner, ensuring the safe operation of batteries and the safe use of vehicles.

Regarding experimental research on ultrasonic detection, the ATA-2000 series of power amplifiers from Antai Electronics has been widely applied in this field. The ATA-2000 series can output an alternating voltage of up to 1600 Vpp, which is capable of driving most piezoelectric ceramics available on the market.

Experiment Name: Ultrasonic Guided Wave Scanning Experiment of Batteries

Experiment Principle: A power amplifier is used to excite piezoelectric ceramics to generate ultrasonic waves, which are then emitted as guided waves at multiple positions on the battery surface. A displacement platform and a vibrometer are used to collect guided wave signals from different positions on the battery surface. The collected ultrasonic guided waves are analyzed to determine whether the battery has aged or sustained any damage.

Experiment Process: An ultrasonic signal generator outputs a signal, which is then amplified by the ATA-2021B power amplifier to excite the piezoelectric ceramic chip to produce ultrasonic guided waves inside the battery. A laser Doppler vibrometer is used to detect the ultrasonic signals inside the battery. The experimental battery is mounted on a displacement platform, which is moved to perform a guided wave signal scan of the battery. A data acquisition card is connected to the vibrometer to collect the guided wave signals detected by the vibrometer. Finally, computer software is used to analyze and process the guided wave signals.

Application Scenarios: Ultrasonic imaging, ultrasonic blood flow monitoring, ultrasonic beauty treatments, ultrasonic bone cutting, nanoimprinting, etc.
