Recharged: How Data Builds Better Batteries
“Our technology is based on a process called electrochemical impedance spectroscopy (EIS). Essentially, we inject a sine wave and measure the battery’s response. It’s used in labs around the world to measure cells,” said Chung. “In terms of the data itself, batteries have collections of data like voltage, current, and temperature, but that isn’t that useful for understanding the overall health. AC impedance, which is what we gather through EIS, is what really lets us understand the health of the battery. That lets us build a degradation curve — to actually monitor the battery over time.”
