Abstract
Battery testing systems and methods are disclosed. One system includes one or more test platforms and a processing system. Each test platform performs ultrasonic scans of batteries. During the scans, each test platform can place pressure upon and measure temperature and open circuit voltages of each battery, transmit ultrasound signals into each battery and generate transmitted signal data in response, detect ultrasound signals reflected by or transmitted through each battery in response to the transmitted ultrasound signals and generate received signal data in response. The processing system can quantify aspects of the signal data and present the aspects to one or more battery models, which compute and assign a state of charge (SOC) and a state of health (SOH) to each battery in response. For example, the processing system can be in a service provider network that receives and analyzes signal data sent from test platforms at different customer facilities.
